Description

本発明は、例えば工作機械等の据え付けに用いられるレベリング装置に関し、特にその高さを調整する機構の構造に係る。   The present invention relates to a leveling device used for installation of a machine tool or the like, for example, and particularly relates to a structure of a mechanism for adjusting the height thereof.

従来より、工作機械や半導体関連の製造装置等、重量の大きな装置類を水平状態に据え付けるために、高さ調整機構を備えたレベリング装置が使用されている。レべリング装置は通常3〜4個が使用されて、工作機械等の各脚部を支持するように配置される。例えば特許文献1、2には、各々楔状の上型、中型、下型の3つを互い違いに3段重ねにしてなり、調整ボルトにより中型を前後方向に移動させることで、その高さを調整するようにしたものが記載されている。   2. Description of the Related Art Conventionally, a leveling device having a height adjusting mechanism has been used to install heavy equipment such as machine tools and semiconductor-related manufacturing devices in a horizontal state. Three to four leveling devices are usually used and arranged to support each leg of a machine tool or the like. For example, in Patent Documents 1 and 2, each of the upper, middle, and lower molds in a wedge shape is alternately stacked in three stages, and the height is adjusted by moving the middle mold in the front-rear direction using adjustment bolts. What you did is described.

特許文献1のものは、上型を下型側に付勢しながら連結するためのピンを設けて3つの型を一体化し、その持ち運びをしやすくしており、その付勢ピンが収容される上型のボス部との干渉を避けるために、中型には凹陥部(同文献には飲み込み溝Gと記載)を設けている。 The thing of patent document 1 provides the pin for urging | biasing and connecting an upper mold | type to a lower mold | type, and united three type | molds and made it easy to carry, The energizing pin is accommodated to avoid interference with the upper mold of the boss portion is provided with a recess (described as swallow groove G 2 is in this document) is the medium-sized.

一方、特許文献2のものでは、上型及び下型のそれぞれに上下に対向するように貫通孔を設けて、上型を貫通させた固定用ボルトを下型の貫通孔(ボルト穴)にねじ込むようにしたり、或いはその下型も貫通させて、アンカーボルトとして床に固定できるようにしている。
特開2006−224230号公報 特許第3192861号公報
On the other hand, in the thing of patent document 2, a through-hole is provided so that each of an upper mold | type and a lower mold | type may oppose up and down, and the fixing bolt which penetrated the upper mold | type is screwed in the through-hole (bolt hole) of a lower mold | type. Or the lower mold is penetrated so that it can be fixed to the floor as an anchor bolt.
JP 2006-224230 A Japanese Patent No. 3192861

ところで、前者の従来例(特許文献1)のものでは、工作機械の脚部等に締結するためのボルトは、上型の上面に開口するねじ孔にねじ込むようにしているが、このボルトを後者の従来例(特許文献2)のように下型まで貫通させたり、或いはその下型も貫通させて床に固定するようにすれば、これにより3つの型を共締めして全体の剛性を高めることができる。   By the way, in the former conventional example (Patent Document 1), a bolt for fastening to a leg portion or the like of a machine tool is screwed into a screw hole opened on the upper surface of the upper die. If it is made to penetrate to the lower mold as in the conventional example (Patent Document 2), or the lower mold is also penetrated and fixed to the floor, the three molds are fastened together to increase the overall rigidity. be able to.

しかしながら、そうして上下に貫通するアンカーボルト等を設けようとすると、同様に上下に延びる付勢ピンとのスペースの取り合いが問題になり、それら両方との干渉を避け得るような大きな空間を内部に設けるとすれば、中型の剛性、強度が不足するか、或いは装置全体を大型化せざるを得ないという実状がある。   However, if an anchor bolt or the like that penetrates up and down is provided in such a way, the space between the urging pin extending in the same manner becomes a problem, and a large space that can avoid interference with both of them is inside. If it is provided, there is a fact that the rigidity and strength of the medium size are insufficient, or the entire apparatus must be enlarged.

本発明は、斯かる点に鑑みてなされたものであり、その目的は、各々楔状の上型、中型及び下型を互い違いに重ね合わせてなる高さ調整機構において、徒な大型化を招くことなく、固定用のボルトが上下に貫通可能な構造としながら、それを容易に持ち運べるようにもすることにある。   The present invention has been made in view of such a point, and an object of the present invention is to cause an increase in size in a height adjustment mechanism in which a wedge-shaped upper mold, a middle mold, and a lower mold are alternately stacked. There is also a structure in which a fixing bolt can be penetrated up and down while being easily carried.

前記の目的を達成するために本発明では、従来例(特許文献1)の付勢ピンに代えて、上型及び下型をその側面において連結する連結部材を設け、この連結部材を上型及び下型の側面に開口させた溝に沿ってスライドさせる構成とした。   In order to achieve the above object, in the present invention, instead of the urging pin of the conventional example (Patent Document 1), a connecting member for connecting the upper mold and the lower mold on the side surface is provided, and this connecting member is connected to the upper mold and It was set as the structure slid along the groove | channel opened on the side surface of the lower mold | type.

すなわち、請求項1の発明は、各々側面視で楔状をなす上型、中型及び下型を上下に重ね合わせてなり、その中型に螺合されて前後方向に延びる調整ボルトと、この調整ボルトを軸支しながらその前後方向への移動を規制する支柱と、を備えて、該調整ボルトの回転によって中型を前後方向に移動させることにより上型の高さを調整する高さ調整機構を対象とする。   In other words, the invention of claim 1 is characterized in that an upper die, a middle die and a lower die each forming a wedge shape in a side view are superposed vertically, an adjustment bolt screwed into the middle die and extending in the front-rear direction, and this adjustment bolt. A height adjustment mechanism that adjusts the height of the upper die by moving the middle die in the front-rear direction by rotation of the adjustment bolt. To do.

そして、前記上型の左右少なくとも一方の側面には、その下面と平行に延びる係合溝を開口形成する一方、下型の少なくとも前記一方の側面には、その上面と平行に延びる係合溝を開口形成し、その上で、上下両端に各々設けられた係合部が、それぞれ前記上型及び下型の各係合溝にスライド自在に係合されて、当該上型及び下型を連結するスライド連結部材を備える構成とした。   An engagement groove extending in parallel with the lower surface is formed on at least one of the left and right side surfaces of the upper mold, while an engagement groove extending in parallel with the upper surface is formed on at least the one side surface of the lower mold. An opening is formed, and the engaging portions provided on both upper and lower ends are slidably engaged with the engaging grooves of the upper mold and the lower mold, respectively, to connect the upper mold and the lower mold. It was set as the structure provided with a slide connection member.

前記構成の高さ調整機構では、調整ボルトの回転により中型を前後方向に移動させると、この中型が下型の上面に沿って前後に摺動しながら上下にも変位するようになり、同時に、その中型の上面に沿って相対的に前後に移動する上型も上下に変位するようになる。よって、仮に工作機械等の大荷重を受けている状態でも、上型上面の高さ、即ち全体の高さ位置をスムーズに変更することができる。   In the height adjustment mechanism of the above configuration, when the middle mold is moved in the front-rear direction by rotating the adjustment bolt, the middle mold is displaced up and down while sliding back and forth along the upper surface of the lower mold. The upper mold that moves relatively back and forth along the upper surface of the middle mold is also displaced up and down. Therefore, the height of the upper surface of the upper mold, that is, the overall height position can be changed smoothly even in a state where a heavy load is applied to a machine tool or the like.

そうして上型の高さが変化すると、この上型の側面に開口する係合溝の高さ位置も変化し、その分、下型の係合溝との間隔(全体的な間隔)も変化することになるが、これら上下の係合溝は各々、側面視楔状をなす中型の上面及び下面に平行に延びていて、それ自体楔状をなすように配置されているから、両溝同士の全体的な間隔が変化しても、そこには所定の間隔となる部位が常に存在する。すなわち、上下の係合溝同士が離れれば、両者間における所定間隔の部位は楔の小端側に移動し、一方、係合溝同士が近づけば大端側に移動するのである。   When the height of the upper mold changes, the height position of the engagement groove opening on the side surface of the upper mold also changes, and the distance (overall distance) from the engagement groove of the lower mold accordingly. The upper and lower engaging grooves extend in parallel to the upper and lower surfaces of the middle mold that is wedge-shaped when viewed from the side, and are arranged so as to form a wedge shape. Even if the overall interval changes, there is always a portion having a predetermined interval. That is, if the upper and lower engaging grooves are separated from each other, a portion having a predetermined interval between them moves to the small end side of the wedge, while if the engaging grooves are brought closer to each other, the portion moves to the large end side.

そこで、前記上型及び下型を連結する連結部材を設け、その上端及び下端の各係合部をそれぞれ上下の各係合溝にスライド自在に係合させれば、この連結部材(スライド連結部材)が前後にスライド移動することによって、前記のように上型の高さ、即ち調整機構の高さが変化しても、それらの連結状態が維持されるようになる。そうしてスライド連結部材によって3つの型を一体的に連結すれば、その持ち運びが容易になる。   Therefore, if a connecting member for connecting the upper die and the lower die is provided and the engaging portions at the upper and lower ends thereof are slidably engaged with the upper and lower engaging grooves, the connecting member (slide connecting member). ) Slides back and forth, so that the connected state is maintained even when the height of the upper die, that is, the height of the adjusting mechanism changes as described above. If the three molds are integrally connected by the slide connecting member, the carrying becomes easy.

前記スライド連結部材は、上型の高さが高くなり、上下の係合溝同士が離れるに連れてその係合溝の構成する楔の小端側に移動する。それが楔の小端に位置してそれ以上、スライド移動できなくなるときが、上型の最高位置であり、反対にスライド連結部材が楔の大端に位置するときが上型の最低位置である。つまり、スライド連結部材は、高さ調整機構の最高位置、最低位置をそれぞれ規定するストッパとしても機能する。   The slide connecting member moves to the small end side of the wedge formed by the engaging grooves as the height of the upper die increases and the upper and lower engaging grooves are separated from each other. When it is located at the small end of the wedge and cannot slide any further, it is the highest position of the upper mold, and conversely, when the slide connecting member is located at the large end of the wedge, it is the lowest position of the upper mold. . That is, the slide connecting member also functions as a stopper that defines the highest position and the lowest position of the height adjusting mechanism.

また、前記スライド連結部材を設ければ、従来例(特許文献1)のような付勢ピンは不用になるので、これとのスペースの取り合いを気にすることなく、上型及び下型の平面視で中央部寄りの部位には、互いに上下に対向する位置にそれぞれ固定用ボルトの貫通孔を形成することができる(請求項2)。中型には、それが前後に移動する際に前記ボルトとの干渉を避けるように溝部や凹陥部等を設ける必要があるが、これはあまり大きくしなくてもよいので、剛性や強度不足の心配は少なく、機構が徒に大型化することもない。   Further, if the slide connecting member is provided, the urging pin as in the conventional example (Patent Document 1) becomes unnecessary, and the upper and lower mold planes do not have to worry about the space between them. The through-holes of the fixing bolts can be formed at positions facing the upper and lower sides in the portion closer to the center as viewed (Claim 2). The middle mold needs to be provided with grooves and recesses so as to avoid interference with the bolt when it moves back and forth, but this does not have to be too large, so there is a concern about lack of rigidity and strength There are few, and the mechanism does not increase in size.

好ましいのはスライド連結部材を中型の側面に固定することであり(請求項3)、こうすれば、中型の前後への移動に同期してスライド連結部材の上下の各係合部が、上型及び下型の各係合溝内を前後に移動することになり、それが引っ掛かったりすることなくスムーズで安定した動作が可能になる。また、スライド連結部材を左右両側に備えれば、これにより3つの型をしっかりと一体化でき、より好ましい(請求項4)。   Preferably, the slide connecting member is fixed to the side surface of the middle mold (Claim 3), and in this way, the upper and lower engaging portions of the slide connecting member are synchronized with the front-rear movement of the middle mold. And it will move back and forth in each engaging groove of the lower mold, and smooth and stable operation is possible without being caught. Further, if the slide connecting members are provided on both the left and right sides, it is more preferable that the three molds can be firmly integrated with each other (claim 4).

前記のような高さ調整機構は、例えば工作機械等の据え付けに用いるレベリング装置に好適であり(請求項5)、その場合に好ましいのは、凹球面からなる円環状の座面を上型の上面にボルト貫通孔を囲むように形成し、その座面上に、据え付ける装置の荷重を受ける円環状の荷重受け部材を摺動自在に載置することである(請求項6)。こうすれば、装置を据え付ける床に傾斜があっても荷重受け部材の揺動によって吸収できる。   The height adjusting mechanism as described above is suitable for a leveling device used for installation of a machine tool or the like, for example (Claim 5). In this case, it is preferable that an annular seating surface formed of a concave spherical surface is used as an upper mold. An annular load receiving member that is formed on the upper surface so as to surround the bolt through hole and receives the load of the installation device is slidably mounted on the seat surface. In this way, even if the floor on which the apparatus is installed is inclined, it can be absorbed by the swing of the load receiving member.

以上のように、本発明に係る高さ調整機構及びレベリング装置によると、楔状の上型、中型及び下型を互い違いに重ね合わせ、その上型及び下型を側面にて連結するスライド連結部材を設けたことで、持ち運びが容易になるとともに、従来までの付勢ピンが不用になるので、これとのスペースの取り合いを気にすることなく、固定用のボルトが上下に貫通可能な構造として、全体の剛性を高めることができる。また、そのボルトとの干渉を避けるために内部に設ける空間はあまり大きくしなくてもよいので、中型の剛性、強度不足を生じる心配はなく、装置全体が徒に大型化することもない。
As described above, according to the height adjusting mechanism and the leveling device of the present invention, the slide-type connecting member that alternately overlaps the wedge-shaped upper mold, the middle mold, and the lower mold and connects the upper mold and the lower mold at the side surfaces is provided. By providing it, it is easy to carry and the conventional urging pin becomes unnecessary, so as a structure that allows the fixing bolt to penetrate vertically without worrying about the space with it, The overall rigidity can be increased. Further, since the space provided in the interior does not have to be so large in order to avoid interference with the bolts, there is no fear that the rigidity and strength of the middle mold will be insufficient, and the entire apparatus will not be increased in size.

以下、本発明の実施の形態を図面に基づいて説明する。尚、以下の好ましい実施形態の説明は、本質的に例示に過ぎず、本発明、その適用物或いはその用途を制限することを意図するものではない。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature, and is not intended to limit the present invention, its application, or its use.

図1〜3は、本発明に係る高さ調整機構を備えたレベリング装置1を示す。図1は装置外観を示す斜視図であり、図2はそのII−II線における断面図、図3は分解斜視図である。このレベリング装置1は、各々側面視で楔状をなす上型2、中型3及び下型4を互い違いに3段重ねしたもので、中型3に螺合されて後方(図1、3では右奥方)に延びる調整ボルト5と、この調整ボルト5を軸支しながらその前後方向への移動を規制する支柱6と、を備えている。   1-3 show the leveling apparatus 1 provided with the height adjustment mechanism based on this invention. 1 is a perspective view showing the appearance of the apparatus, FIG. 2 is a sectional view taken along the line II-II, and FIG. 3 is an exploded perspective view. The leveling device 1 is formed by alternately stacking an upper mold 2, a middle mold 3 and a lower mold 4 each having a wedge shape in a side view, and is screwed into the middle mold 3 to be rearward (in the right rear in FIGS. 1 and 3). And a support column 6 that regulates movement in the front-rear direction while pivotally supporting the adjustment bolt 5.

詳細は以下に述べるが、支柱6は、その上下両端部をそれぞれ上型2及び下型4の案内孔2b、4bに摺動自在に嵌挿されており、この支柱6によって前後への移動を規制されている調整ボルト5が回転すると、中型3が上型2及び下型4に対して相対的に前後方向に移動し、これによって上型2の上面の高さ、即ちレベリング装置1の高さ位置が変更されるようになる。   Although details will be described below, the upper and lower ends of the column 6 are slidably inserted into the guide holes 2b and 4b of the upper mold 2 and the lower mold 4, respectively. When the regulated adjusting bolt 5 is rotated, the middle mold 3 moves in the front-rear direction relative to the upper mold 2 and the lower mold 4, thereby the height of the upper surface of the upper mold 2, that is, the height of the leveling device 1. The position will be changed.

また、本発明の特徴として、レベリング装置1の左右両側にはそれぞれスライド連結金具7,7が配設されており、前記のような中型3の上型2及び下型4に対する前後移動を許容し、且つそれに伴い高さが変化しても、それら3つの型2〜4を一体的に連結するようになっている。こうして3つの型2〜4を一体化すれば、レベリング装置1の持ち運びが比較的容易に行える。以下、下型4から順に詳しく説明する。   Further, as a feature of the present invention, slide coupling fittings 7 and 7 are provided on the left and right sides of the leveling device 1, respectively, to allow the back and forth movement with respect to the upper mold 2 and the lower mold 4 of the middle mold 3 as described above. And even if height changes in connection with it, these 3 type | molds 2-4 are connected integrally. If the three molds 2 to 4 are integrated in this way, the leveling device 1 can be carried relatively easily. Hereinafter, the lower mold 4 will be described in detail in order.

−下型−
下型4は、上面に一対の傾斜面4a,4aを有するブロックであり、図の例では傾斜面4a,4aは、下型4の上面における左右両側寄りにそれぞれ帯状に設けられて、前端部(図1、3では左手前側の端部)から後端側にかけて上り傾斜となっている。下型4の後部は、傾斜面4aの後端から段状に低くなっており、その中間部位には支柱6の下端部が嵌挿される断面円形の案内孔4bが開口している。
-Lower mold-
The lower mold 4 is a block having a pair of inclined surfaces 4a and 4a on the upper surface. In the example shown in the figure, the inclined surfaces 4a and 4a are provided in strips on the left and right sides of the upper surface of the lower mold 4, respectively. It is an upward slope from the rear end side (in FIG. 1 and FIG. 3, the left front end). The rear portion of the lower mold 4 is stepped lower from the rear end of the inclined surface 4a, and a circular guide hole 4b into which the lower end portion of the column 6 is fitted is opened at an intermediate portion thereof.

この案内孔4bの左右両側から上方に立ち上がる立壁部4c,4cが形成される一方、案内孔4bの前側には調整ボルト5のカラー51との干渉を避けるように凹部4dが形成されている。また、その凹部4dの前側に隣接して断面円形の孔部4e,4eが開口している。この孔部4eの一方は、内周面にねじが螺刻されたねじ孔であって、図示しない固定用ボルトの下端がねじ込まれる。他方の孔部4eは貫通孔であり、図示しないアンカーボルトが挿入される。   Standing wall portions 4c, 4c that rise upward from the left and right sides of the guide hole 4b are formed, while a recess 4d is formed on the front side of the guide hole 4b so as to avoid interference with the collar 51 of the adjusting bolt 5. Further, holes 4e and 4e having a circular cross section are opened adjacent to the front side of the recess 4d. One of the holes 4e is a screw hole in which a screw is threaded on the inner peripheral surface, and a lower end of a fixing bolt (not shown) is screwed in. The other hole 4e is a through hole into which an anchor bolt (not shown) is inserted.

さらに、下型4の左右両側面には、それぞれ、上面の傾斜面4aに平行な係合溝4fが概ねその傾斜面4aの前端部から後端部に亘って形成されていて、そこにはスライド連結金具7(スライド連結部材)の下端の折曲部7a(係合部)がスライド自在に係合されるようになっている。   Further, on both the left and right side surfaces of the lower mold 4, engagement grooves 4f parallel to the inclined surface 4a on the upper surface are formed from the front end portion to the rear end portion of the inclined surface 4a. A bent portion 7a (engagement portion) at the lower end of the slide connection fitting 7 (slide connection member) is slidably engaged.

−中型−
中型3は、その上下両面にそれぞれ傾斜面3a,3bを有し、それらは、前記した下型4上面の傾斜面4aや後述する上型2下面の傾斜面2aに対応して、上下各面における左右両側寄りに設けられている。中型3の上面の傾斜面3a,3aは、図示の如く前端部から後端部にかけて下り傾斜となっており、一方、下面の傾斜面3b(図5も参照)は、前端部から後端部にかけて上り傾斜となっている。
-Medium-
The middle die 3 has inclined surfaces 3a and 3b on both upper and lower surfaces, respectively, which correspond to the inclined surface 4a on the upper surface of the lower die 4 and the inclined surface 2a on the lower surface of the upper die 2 described later. It is provided near both left and right sides. The inclined surfaces 3a, 3a on the upper surface of the middle mold 3 are inclined downward from the front end portion to the rear end portion as shown in the figure, while the inclined surface 3b (see also FIG. 5) on the lower surface is from the front end portion to the rear end portion. It has an upward slope.

また、中型3は、そうして傾斜面3a,3bの形成されている左右両側寄りの部位を除いた中央部の後半部分が欠落しており(換言すれば凹陥部が形成されており)、それら左右両側の部分が前部において連結された平面視コ字状になっている。その連結部の左右方向の中央部位には、調整ボルト5の軸部が螺合されるねじ孔3cが前後方向に貫通形成されている。また、ねじ孔3cの左右両側には、それぞれ、図示しないアンカーボルト等との干渉を回避するように、連結部の後面から前方に向かって凹陥するU字断面の凹部3d,3dが形成されている。   In addition, the middle mold 3 is missing the latter half of the central portion except for the portions near the left and right sides where the inclined surfaces 3a and 3b are formed (in other words, a recessed portion is formed). These left and right side portions are U-shaped in a plan view connected at the front. A screw hole 3c into which the shaft portion of the adjustment bolt 5 is screwed is formed in the front-rear direction at a central portion in the left-right direction of the connecting portion. Further, U-shaped concave portions 3d and 3d that are recessed forward from the rear surface of the connecting portion are formed on the left and right sides of the screw hole 3c so as to avoid interference with an anchor bolt (not shown). Yes.

前記中型3の下面の傾斜面3b,3bは、下型4上面の傾斜面4a,4aに摺動自在に重ね合わされており、前記のように調整ボルト5の回転によって前後に移動するときに、中型3は下型4の傾斜面4aに沿って上下方向にも変位するようになる。すなわち、中型3は、前進するのに連れて下型4の傾斜面4aを登ることになり、後退するのに連れて傾斜面4aを下ることになる。   The inclined surfaces 3b, 3b on the lower surface of the middle die 3 are slidably superimposed on the inclined surfaces 4a, 4a on the upper surface of the lower die 4, and when moving back and forth by the rotation of the adjusting bolt 5 as described above, The middle mold 3 is also displaced in the vertical direction along the inclined surface 4 a of the lower mold 4. That is, the middle mold 3 climbs the inclined surface 4a of the lower mold 4 as it moves forward, and descends the inclined surface 4a as it moves backward.

さらに、中型3の左右両側面には、それぞれ、前後方向の中央付近(図の例ではやや前より)にスライド連結金具7を締結するための2つのねじ孔3e,3eが前後に並んで開口しており、該スライド連結金具7の上下の略中央に形成された取付部7bが重ね合わされてねじ止めされるようになっている。   Further, two screw holes 3e, 3e for fastening the slide coupling metal 7 near the center in the front-rear direction (slightly forward in the example in the figure) are opened on the left and right side surfaces of the middle mold 3 side by side. A mounting portion 7b formed at the approximate center of the upper and lower sides of the slide coupling metal 7 is overlapped and screwed.

−上型−
上型2は概ね前記下型4を上下に反転させた構造であり、その下面に一対の傾斜面2aを有する(図5も参照)。この傾斜面2a,2aは、中型3上面の傾斜面3a,3aに対応して上型2の下面における左右両側寄りの部位にそれぞれ前端部から後端部にかけて下り傾斜となるように設けられている。これらの傾斜面2a,2aが中型3上面の傾斜面3a,3aに沿って前後に相対移動すると、上型2は、中型3に対して上下方向にも変位するようになる。
-Upper mold-
The upper die 2 has a structure in which the lower die 4 is generally inverted up and down, and has a pair of inclined surfaces 2a on its lower surface (see also FIG. 5). The inclined surfaces 2a, 2a are provided at portions located on the left and right sides of the lower surface of the upper die 2 so as to be inclined downward from the front end portion to the rear end portion, corresponding to the inclined surfaces 3a, 3a on the upper surface of the middle die 3. Yes. When these inclined surfaces 2 a, 2 a are relatively moved back and forth along the inclined surfaces 3 a, 3 a on the upper surface of the middle mold 3, the upper mold 2 is also displaced in the vertical direction with respect to the middle mold 3.

また、上型2の後部は前記傾斜面2aの後端から段状に高くなっていて、その中央部位に支柱6上端の嵌挿される案内孔2bが開口している。この案内孔2bの左右両側には立壁部2c,2cが、また前側には凹陥部2dがそれぞれ形成され、さらにその凹陥部2dの前側には下型4の孔部4e,4eの上方に対向するように、ボルトの貫通孔2e,2eが形成されている。この貫通孔2e,2eは、いずれも内周面にねじの螺刻されていないものである。   Further, the rear portion of the upper mold 2 is stepped from the rear end of the inclined surface 2a, and a guide hole 2b into which the upper end of the support 6 is fitted is opened at the center portion. Standing wall portions 2c and 2c are formed on the left and right sides of the guide hole 2b, and a recessed portion 2d is formed on the front side, and the front side of the recessed portion 2d is opposed to the upper side of the holes 4e and 4e of the lower mold 4. As shown, bolt through holes 2e and 2e are formed. The through holes 2e and 2e are not screwed on the inner peripheral surface.

それらの貫通孔2e,2eが開口する上型3の上面には、円環状の受け座21(荷重受け部材)の載置される座面2fがやや上方に突出して形成されている。この座面2fは、前記貫通孔2e,2eの開口部を囲んで円環状に形成されるとともに、凹球面からなるもので、これに対応して受け座21の下部に形成されている凸球面と摺動自在に接している。この受け座21の揺動によって、レベリング装置1を据え付ける床面の傾斜を吸収することができる。   On the upper surface of the upper mold 3 where the through holes 2e and 2e are opened, a seat surface 2f on which an annular receiving seat 21 (load receiving member) is placed is formed to protrude slightly upward. The seat surface 2f is formed in an annular shape so as to surround the openings of the through holes 2e and 2e, and is formed of a concave spherical surface, and a convex spherical surface formed on the lower portion of the receiving seat 21 corresponding to this. And slidably touching. By the swinging of the receiving seat 21, the inclination of the floor surface on which the leveling device 1 is installed can be absorbed.

さらに、上型2の左右両側面には、それぞれ、下面の傾斜面2aに平行な係合溝2gが概ねその傾斜面2aの前端部から後端部に亘って形成されていて、そこにはスライド連結金具7(スライド連結部材)の上端の折曲部7a(係合部)がスライド自在に係合されるようになっている。   Further, on both the left and right side surfaces of the upper mold 2, engagement grooves 2g parallel to the inclined surface 2a of the lower surface are formed from the front end portion to the rear end portion of the inclined surface 2a. A bent portion 7a (engagement portion) at the upper end of the slide connection fitting 7 (slide connection member) is slidably engaged.

−調整ボルト及び支柱−
調整ボルト5は、その基端に設けられた頭部5aから先端側へ向かう所定範囲に亘って軸部5bにねじが螺刻されておらず、この範囲が支柱6の軸受孔6aによって軸支されることで、スムーズに回転するようになっている。そうしてねじが螺刻されていない範囲とその先のねじが螺刻された範囲との境界には環状溝5cが形成されていて、この環状溝5cにはカラー51を貫通する留めねじ(図示せず)の先端が係止されている。
-Adjustment bolts and struts-
The adjustment bolt 5 is not screwed into the shaft portion 5b over a predetermined range from the head portion 5a provided at the base end toward the distal end side, and this range is supported by the bearing hole 6a of the column 6. By doing so, it is designed to rotate smoothly. An annular groove 5c is formed at the boundary between the area where the screw is not screwed and the area where the screw is screwed, and a retaining screw (through the collar 51) is formed in the annular groove 5c. The tip of (not shown) is locked.

これによりカラー51は、ボルト5の軸部5bに対しその軸方向に移動不能に取り付けられ、ワッシャ52を介して支柱6の前部に接している。一方、支柱6の後部にはワッシャ53を介してボルト5の頭部5aが接しており、支柱6はカラー51と調整ボルト5の頭部5aとの間に挟まれてボルト軸方向には移動不能になっている。このことで、調整ボルト5がその前後方向への移動を支柱6によって規制されることになる。   Accordingly, the collar 51 is attached to the shaft portion 5 b of the bolt 5 so as not to move in the axial direction, and is in contact with the front portion of the support column 6 through the washer 52. On the other hand, the head 5a of the bolt 5 is in contact with the rear part of the support 6 through a washer 53, and the support 6 is sandwiched between the collar 51 and the head 5a of the adjusting bolt 5 and moves in the bolt axis direction. It is impossible. As a result, the movement of the adjustment bolt 5 in the front-rear direction is restricted by the support 6.

−スライド連結金具−
スライド連結金具7は例えば薄板のプレス成形品であり、図4に拡大して断面で示すように、上端及び下端にそれぞれ裏側へ折り曲げられた折曲部7a,7aが形成されて、上型2及び下型4の各係合溝2g,4fに係合されるとともに、スライド連結金具7の中央部には裏側へ突出するように折り曲げられて土手状の取付部7bが形成され、そこには2つの丸穴7c,7cが並んで設けられている。この2つの丸穴7c,7cは、中型3の側面に開口する2つのねじ孔3e,3eに重ね合わされ、それぞれにねじ71、71が挿入されて締結される。
-Slide coupling bracket-
The slide coupling metal 7 is, for example, a thin plate press-molded product. As shown in an enlarged cross-sectional view in FIG. 4, the upper die 2 is formed with bent portions 7a and 7a bent at the upper and lower ends, respectively. And the engaging groove 2g, 4f of the lower mold 4 and a bank-like mounting portion 7b is formed at the center portion of the slide coupling fitting 7 so as to be protruded to the back side. Two round holes 7c, 7c are provided side by side. The two round holes 7c and 7c are overlapped with the two screw holes 3e and 3e opened on the side surface of the middle mold 3, and screws 71 and 71 are inserted and fastened to the two screw holes 3e and 3e, respectively.

そうして中央の取付部7bが中型3の側面に重ね合わされて締結されると、スライド連結金具7の上下両端の折曲部7a,7aが、それぞれ、上型2及び下型4の各係合溝2g、4fにスライド自在に係合される。ここで、図5のように側方から視ると、上型2及び下型4の各係合溝2g、4fは、レベリング装置1の後側から前側に向かって徐々に間隔が拡大する楔状に配置されているから、スライド連結金具7の上下の折曲部7a,7aも前記と同じ楔状をなすように傾斜状態で設けられている。   When the central mounting portion 7b is overlapped with the side surface of the middle die 3 and fastened, the bent portions 7a and 7a at the upper and lower ends of the slide coupling metal 7 are respectively connected to the upper die 2 and the lower die 4, respectively. The mating grooves 2g and 4f are slidably engaged. Here, when viewed from the side as shown in FIG. 5, the engagement grooves 2 g and 4 f of the upper mold 2 and the lower mold 4 are wedge-shaped whose intervals gradually increase from the rear side to the front side of the leveling device 1. Therefore, the upper and lower bent portions 7a, 7a of the slide coupling metal 7 are also provided in an inclined state so as to form the same wedge shape as described above.

−レベリング装置の動作−
次に、この実施形態のレベリング装置1(高さ調整機構)の動作について図5を参照して説明する。同図(a)に示すのは中型3が上型2及び下型4に対して前後にずれていない状態であり、このときの中型3の位置を以下、基準位置と呼ぶ。この基準位置では、スライド連結金具7が上型2及び下型4の各係合溝2g、4fの中央に位置付けられる。また、中型3下面の傾斜面3b全体が下型4の傾斜面4aに重なるとともに、中型3上面の傾斜面3a全体に上型2の傾斜面2aが重なっていて、安定性が非常に高い。
-Operation of leveling device-
Next, the operation of the leveling device 1 (height adjustment mechanism) of this embodiment will be described with reference to FIG. FIG. 4A shows a state in which the middle mold 3 is not displaced back and forth with respect to the upper mold 2 and the lower mold 4, and the position of the middle mold 3 at this time is hereinafter referred to as a reference position. In this reference position, the slide coupling fitting 7 is positioned at the center of the engagement grooves 2g and 4f of the upper mold 2 and the lower mold 4. In addition, the entire inclined surface 3b on the lower surface of the middle mold 3 overlaps with the inclined surface 4a of the lower mold 4, and the inclined surface 2a of the upper mold 2 overlaps with the entire inclined surface 3a on the upper surface of the middle mold 3. Therefore, the stability is very high.

前記の状態から調整ボルト5を左回りに回転させると、これによる推力を受けて中型3が前方に移動する。このとき調整ボルト5は、支柱6によって前後方向への移動を規制されている。中型3は、下型4の傾斜面4aに沿って前方に移動しながら徐々に下降してゆき、これとともに調整ボルト5も下降して、支柱6が上型2及び下型4の案内孔2b,4b内を下降するようになる。   When the adjustment bolt 5 is rotated counterclockwise from the above state, the middle mold 3 moves forward by receiving the thrust force. At this time, the adjustment bolt 5 is restricted from moving in the front-rear direction by the support 6. The middle mold 3 gradually descends while moving forward along the inclined surface 4 a of the lower mold 4, and the adjustment bolt 5 is also lowered with this, so that the support 6 is guided by the guide holes 2 b of the upper mold 2 and the lower mold 4. , 4b.

また、そうして中型3が前方に移動すると、この中型3に対し相対的には後退する上型2は、中型3の上面の傾斜面3aに沿って徐々に下降することになり、前記した中型3の下降と合わせて、上型2の上面の高さ、即ちレベリング装置1全体の高さが徐々に低くなってゆく。こうして上型2が下降してゆくとその係合溝2gの高さも低くなって、下型4の係合溝4fとの間隔(全体的な間隔)が狭くなってゆく。   In addition, when the middle mold 3 moves forward, the upper mold 2 that retreats relative to the middle mold 3 gradually descends along the inclined surface 3a on the upper surface of the middle mold 3. Along with the lowering of the middle mold 3, the height of the upper surface of the upper mold 2, that is, the height of the entire leveling device 1 gradually decreases. When the upper die 2 is lowered in this manner, the height of the engaging groove 2g is lowered, and the interval (overall interval) between the lower die 4 and the engaging groove 4f is reduced.

そのように係合溝2g,4fの間隔が全体としては狭くなっていっても、中型3と共に前方へ移動するスライド連結金具7は、楔状に配置された2つの係合溝2g,4fに跨ってその大端側に移動することになるから、当該スライド連結金具7による連結部位においては両係合溝2g,4fの間隔は変化しない。よって、前記のように上型2の高さが変化しても、それと中型3及び下型4との連結状態は維持される。   Thus, even if the interval between the engagement grooves 2g and 4f is narrow as a whole, the slide coupling fitting 7 that moves forward together with the middle mold 3 straddles the two engagement grooves 2g and 4f arranged in a wedge shape. Therefore, the distance between the engagement grooves 2g and 4f does not change at the connection portion by the slide connection fitting 7. Therefore, even if the height of the upper mold 2 changes as described above, the connected state between the middle mold 3 and the lower mold 4 is maintained.

そして、同図(b)に示すように中型3が最大限、前方に移動すると、スライド連結金具7が上型2及び下型4の各係合溝2g、4fの前端に、即ち、それらの溝の間隔が最も大きな楔の大端に位置して、それ以上、前方には移動できなくなる。このとき、レベリング装置1の高さが最も低くなる(以下、最低位置と呼ぶ)。つまり、スライド連結金具7はレベリング装置1の最低位置を規定するストッパとして機能する。   Then, as shown in FIG. 5 (b), when the middle die 3 moves forward as much as possible, the slide coupling bracket 7 is placed at the front ends of the engaging grooves 2g, 4f of the upper die 2 and the lower die 4, that is, The groove is located at the large end of the wedge with the largest gap and cannot move forward any further. At this time, the leveling device 1 has the lowest height (hereinafter referred to as the lowest position). That is, the slide coupling metal 7 functions as a stopper that defines the lowest position of the leveling device 1.

一方、前記図(a)の基準位置から調整ボルト5を右回りに回転させると、今度は、中型3が下型4の傾斜面4aに沿って後方移動しながら徐々に上昇し、これに伴い調整ボルト5や支柱6も上昇するようになる。また、その中型3に対し相対的には前進する上型2は、中型3上面の傾斜面3aに沿って上昇することになり、前記中型3の上昇と合わせて、上型2の上面、即ちレベリング装置1の高さが徐々に高くなってゆく。   On the other hand, when the adjustment bolt 5 is rotated clockwise from the reference position in FIG. 1 (a), the middle die 3 gradually rises while moving backward along the inclined surface 4a of the lower die 4, and accompanying this, The adjustment bolt 5 and the column 6 are also raised. Further, the upper die 2 that moves forward relative to the middle die 3 rises along the inclined surface 3a on the upper surface of the middle die 3, and together with the rise of the middle die 3, the upper surface of the upper die 2, that is, The height of the leveling device 1 gradually increases.

そうして上型2が上昇してゆくときには、その係合溝2gと下型4の係合溝4fとの間隔は全体としては拡がることになるが、これと同期するようにスライド連結金具7が中型3と共に後方に、即ち楔状をなす係合溝2g,4fの小端側に移動することになるから、当該スライド連結金具7による連結部位においては両係合溝2g,4fの間隔は変化せず、上型2、中型3及び下型4の連結状態が維持される。   Thus, when the upper die 2 is raised, the interval between the engaging groove 2g and the engaging groove 4f of the lower die 4 is expanded as a whole, but the slide coupling metal 7 is synchronized with this. Is moved rearward together with the middle mold 3, that is, to the small end side of the engaging grooves 2g and 4f having a wedge shape, the distance between the engaging grooves 2g and 4f is changed at the connecting portion by the slide connecting bracket 7. Without being connected, the connected state of the upper mold 2, the middle mold 3 and the lower mold 4 is maintained.

尚、図示しない固定用ボルトやアンカーボルトが上型2から下型4にかけて上下に貫通している場合、それらは、中型3が後方に移動するに連れて、その連結部の後部に形成された凹部3dに飲み込まれてゆくことになり、中型3と干渉することはない。   When fixing bolts and anchor bolts (not shown) penetrate vertically from the upper die 2 to the lower die 4, they are formed at the rear part of the connecting portion as the middle die 3 moves rearward. It will be swallowed by the recess 3d and will not interfere with the middle mold 3.

そして、同図(c)に示すように中型3が最大限、後方に移動すれば、スライド連結金具7が上型2及び下型4の各係合溝2g、4fの後端に、即ち、それらの溝の間隔が最も小さな楔の小端に位置して、それ以上、後方には移動できなくなる。このとき、レベリング装置1の高さが最も高くなる(以下、最高位置と呼ぶ)。こうしてスライド連結金具7はレベリング装置1の最高位置をも規定する。   Then, as shown in FIG. 5C, when the middle die 3 moves to the maximum extent, the slide coupling metal 7 is placed at the rear ends of the engaging grooves 2g, 4f of the upper die 2 and the lower die 4, that is, The gap between these grooves is located at the small end of the smallest wedge and cannot move backward any further. At this time, the leveling device 1 has the highest height (hereinafter referred to as the highest position). Thus, the slide coupling 7 also defines the highest position of the leveling device 1.

したがって、この実施形態1に係るレベリング装置1によると、まず、各々楔状をなす上型2、中型3及び下型4を互い違いに重ね合わせ、中型3を上型2、下型4に対し前後に相対移動させることによって、その高さを変更する構造としたので、工作機械等の大きな荷重を受ける状態でもスムーズな高さ調整が行える。   Therefore, according to the leveling device 1 according to the first embodiment, first, the upper mold 2, the middle mold 3 and the lower mold 4 each having a wedge shape are alternately stacked, and the middle mold 3 is moved back and forth with respect to the upper mold 2 and the lower mold 4. Since the height is changed by relative movement, the height can be smoothly adjusted even under a large load such as a machine tool.

また、前記3つの型2〜4を左右両側のスライド連結金具7によってしっかりと連結できるので、その持ち運びが容易になる。従来までの付勢ピンが不用になることから、これとのスペースの取り合いを気にすることなく、アンカーボルト等を上下に貫通させて、全体剛性を向上することも可能になる。   Further, since the three molds 2 to 4 can be firmly connected by the slide connecting metal fittings 7 on both the left and right sides, it is easy to carry. Since the conventional urging pin is not required, it is possible to improve the overall rigidity by passing the anchor bolt or the like vertically without worrying about the space with the urging pin.

その場合、中型3には、それが前後に移動する際にアンカーボルト等との干渉を避けるように凹陥部を設けなくてはならないが、前記の如く付勢ピン等とのスペースの取り合いがないので、凹陥部はあまり大きくしなくてもよく、中型3の剛性や強度が不足する心配は少ない。また、装置全体が徒に大型化することもない。   In that case, the middle mold 3 must be provided with a recessed portion so as to avoid interference with the anchor bolt or the like when it moves back and forth, but there is no space for the biasing pin or the like as described above. Therefore, the recessed portion does not have to be so large, and there is little fear that the rigidity and strength of the middle mold 3 are insufficient. Moreover, the entire apparatus does not increase in size.

さらに、スライド連結金具7は中型3の側面に固定されて、これと一体に前後に移動するようになっていて、その中型3の前後の移動に伴い上型2及び下型4の係合溝2g,4f同士の全体的な間隔が変化しても、それらの間で同じ間隔となる部位に常に位置するようになるから、このスライド連結金具7の上下の折曲部7a,7aが係合溝2g,4fに引っ掛かったりすることもなく、スムーズで安定した動作が可能になる。   Further, the slide coupling metal 7 is fixed to the side surface of the middle mold 3 so as to move back and forth integrally therewith, and the engagement grooves of the upper mold 2 and the lower mold 4 as the middle mold 3 moves back and forth. Even if the overall interval between 2g and 4f changes, the upper and lower bent portions 7a and 7a of the slide coupling metal 7 are engaged because they are always located at the same interval between them. A smooth and stable operation is possible without being caught in the grooves 2g and 4f.

尚、本発明に係るレベリング装置1の構成は前記実施形態のものに限定されず、その他の種々の構成をも包含する。例えばスライド連結金具7は、レベリング装置1の左右両側ではなく、いずれか一方のみに配設するだけでもよいし、必ずしも中型3の側面に固定しなくてもよい。   In addition, the structure of the leveling apparatus 1 which concerns on this invention is not limited to the thing of the said embodiment, It includes other various structures. For example, the slide coupling 7 may be disposed only on either one of the leveling device 1, not on both the left and right sides, and may not necessarily be fixed to the side surface of the middle mold 3.

また、前記実施形態では上型2及び下型4にそれぞれボルト貫通孔2eや孔部4eを設けているが、これも必須の構成ではないし、上型2上面の座面2fや、これに載置される受け座21も省略可能である。さらに、本発明に係る高さ調整機構は、レベリング装置1に限らず、高さ調整が必要な各種用途に適用可能である。   In the above-described embodiment, the upper die 2 and the lower die 4 are each provided with the bolt through holes 2e and the hole portions 4e. However, this is not an indispensable configuration, and the seat surface 2f on the upper surface of the upper die 2 or mounted thereon. The seat 21 to be placed can also be omitted. Furthermore, the height adjustment mechanism according to the present invention is not limited to the leveling device 1 and can be applied to various applications that require height adjustment.

以上の如く本発明に係る高さ調整機構を備えたレべリング装置は、固定用のボルトが上下に貫通可能な構造としても徒に大型化を招くことがなく、持ち運びも比較的容易であるから、工作機械等の据え付けに用いて好適である。   As described above, the leveling device provided with the height adjusting mechanism according to the present invention does not cause an increase in size even if the fixing bolt can be vertically penetrated and is relatively easy to carry. Therefore, it is suitable for installation of machine tools and the like.
