TECHNICAL FIELD OF THE INVENTION
The present invention relates to an inclined stopper device for positioning an inclined cutting position of a cutting machine body having a saw blade in a portable cutting machine such as a circular saw.
[0002]
[Prior art]
Conventionally, as a technique relating to this type of stopper device, for example, a technique disclosed in JP-A-2001-232515 has been provided. 9 to 11 show a cutting machine 50 provided with the conventional stopper device. 9 to FIG. 1, FIG. 10 to FIG. 3, and FIG. 11 to FIG. Further, as shown in FIG. 9, the cutting material W is cut by moving the cutting machine 50 to the right side in the drawing. Hereinafter, the direction in which the cutting operation proceeds with respect to the moving direction of the cutting machine 50 is referred to as the cutting progress direction.
The cutting machine 50 is a so-called portable saw, and includes a base 51 mounted on the upper surface of the cutting material W, and a cutting machine main body 52 supported by the base 51 so as to be tiltable. The cutting machine main body 52 includes a saw blade 53 that is rotated by an electric motor (not shown). The lower half of the saw blade 53 is covered by a safety cover 54 that can be opened and closed. The saw blade 53 and the safety cover 54 protrude from the lower surface of the base 51 via a rectangular window 51 a provided in the base 51.
[0003]
Further, the cutting machine main body 52 is supported by the base 51 in a state where the cutting machine main body 52 can be tilted in the left and right directions within a certain range with respect to the cutting progress direction via tilt support brackets 55 and 56 provided on the front and rear portions of the base 51. Have been. The cutting machine main body 52 has a position where the saw blade 53 is orthogonal to the base 51 as shown in FIG. 10 (right angle cutting position), and a counterclockwise direction as shown in FIG. It is supported so as to be tiltable between a position (inclination cut position) in which the upper portion of the cutting machine main body 52 is displaced rightward in the traveling direction (in a direction in which the upper portion is displaced to the right) within a certain range. By positioning the cutting machine main body 52 at the right-angled cutting position, so-called right-angled cutting (a cutting mode in which the cut surface of the cutting material W is at right angles to the upper surface) can be performed, and by positioning the cutting machine body at the inclined cutting position, the so-called tilted position Cutting (a cutting mode in which the cut surface of the cut material W is inclined with respect to the upper surface) can be performed.
A stopper member 57 is provided in the vicinity of the front tilting support portion of the cutting machine main body 52 thus provided (near the tilting support bracket 55). As shown in FIG. 11, by contacting the stopper member 57 with the upper surface of the base 51, the inclined cutting position of the cutting machine body 52 can be positioned. Usually, a bolt is used for this type of stopper member, and in this case, the inclination angle of the cutting machine body can be accurately positioned by adjusting the screwing amount of the bolt.

[Problems to be solved by the invention]
However, the conventional stopper member 57 has the following problems. That is, in this type of cutting machine, a so-called edge-cut saw or plunge saw is used, and a range indicated by reference symbol A in FIGS. 10 and 11 of the base 51 (the cutter main body 52 is positioned with respect to the saw blade 53). There is provided a base having a base (hereinafter, referred to as a narrow base) having no portion corresponding to the side opposite to the side. According to the cutting machine having the narrow base, since the base does not exist on the right side in the cutting direction with respect to the saw blade, the saw blade can be brought closer to the wall, for example, in a floor material cutting operation, Thus, a portion closer to the wall can be cut.
However, in the case of this narrow base, since there is no portion where the stopper member 57 comes into contact, the stopper member 57 (inclined stopper device) cannot be applied to this type of cutting machine. For this reason, a cutting machine having a narrow base has not been provided with a tilt stopper device of this type.
Therefore, the present invention provides an inclined stopper device that can be applied to a cutting machine having a narrow base, and that accurately positions an inclined cutting position of a cutting machine body. The purpose is to:
[0006]
[Means for solving the problem]
Therefore, the present invention provides an inclination stopper device having the configuration described in the above claim.
According to the tilt stopper device of the first aspect, the stopper member provided on the left side in the cutting progress direction of the cutting machine body with respect to the saw blade is provided on the stopper receiving portion provided on the left side in the cutting progress direction of the base with respect to the saw blade. Since the cutting machine main body is positioned at the inclined cutting position in contact with the cutting machine body, even if the cutting machine has a narrow base having no portion corresponding to the range on the right side in the cutting progress direction with respect to the saw blade, the cutting machine main body Can be accurately positioned.
According to the inclined stopper device of the second aspect, in a state where one or both of the stopper member and the stopper receiving portion is located at the non-stopper position, the cutting machine main body does not move in any of the right and left directions in the cutting progress direction. It can be tilted without any restrictions. On the other hand, in a state where one or both of the stopper member and the stopper receiving portion is located at the stopper position, the stopper member comes into contact with the stopper receiving portion, so that the cutting machine body moves leftward in the cutting progress direction (right angle cutting position side). Is restricted, whereby the cutting machine body is positioned at the inclined cutting position. For this reason, according to the inclination stopper device of the second aspect, the cutting machine main body can be accurately positioned at the inclined cutting position in the cutting machine having the narrow base.
According to the inclination stopper device of the third aspect, even if the cutting machine has a narrow base having no portion corresponding to the range on the right side in the cutting progress direction with respect to the saw blade, the cutting machine body can be used. Positioning can be accurately performed at a plurality of inclined cutting positions (for example, 30 ° or 45 ° or 60 °), and the inclination angle can be arbitrarily selected according to work.
According to the inclined stopper device of the fourth aspect, the stopper member provided on the cutting machine body on the right side in the cutting progress direction with respect to the saw blade is provided on the stopper receiving portion provided on the base on the right side in the cutting progress direction with respect to the saw blade. Since the cutting machine body is positioned at the inclined cutting position by abutting, even if the cutting machine has a narrow base having no portion corresponding to the range on the left side in the cutting progress direction with respect to the saw blade, the cutting machine The inclined cutting position of the main body can be accurately positioned.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a cutting machine 1 provided with a tilt stopper device 10 of the present embodiment described below. The cutting machine 1 is a so-called portable circular saw, and includes a base 2 placed on a cutting material W and a cutting machine main body 30 having a circular saw blade 31. The cutting machine advances the cutting by moving it to the right in FIG. Therefore, in the following description, the direction moving to the right in FIG. Further, with respect to the tilting direction of the cutting machine body 30 and the saw blade 31, the direction in which the upper side of the saw blade 31 is displaced rightward in the cutting direction is simply referred to as the cutting direction right, and the upper side of the saw blade 31 is left in the cutting direction. The direction displaced toward the cutting direction is also simply referred to as the cutting progress direction left side.
The base 2 is the aforementioned narrow base, and does not have a portion corresponding to a range on the right side of the saw blade 31 in the cutting progress direction (range A in FIGS. 10 and 11).
The cutting machine main body 30 includes a blade case 32 that covers the saw blade 31. The front end and the rear end of the blade case 32 in the cutting progress direction are supported on the upper surface of the base 2 via tilt support shafts 33 and 34 provided coaxially with each other. As a result, the cutting machine body 30 moves the saw blade 31 perpendicular to the base 2 at a right angle cutting position (the position indicated by a solid line in the figure) as shown in FIG. It can be tilted between an inclined cutting position (position indicated by a two-dot chain line in the figure, for example, 45 °) inclined in the direction of moving to the right.
On the front side (the right end side in FIG. 1) in the cutting progress direction of the base 2, a tilt support plate 21 is provided so as to project upward. On the other hand, a tilting plate 39 is provided on the front side of the blade base 32 in the cutting direction in the cutting direction and at the front end of the sub base 38 in the cutting direction. The tilting plate 39 is superimposed on the tilting support plate 21 so as to be movable in the plane direction. The relative position between the tilting plate 39 and the tilting support plate 21 is fixed by tightening the fixing screw 40, whereby the saw blade 31 is fixed so as not to tilt at the right angle cutting position or the inclined cutting position or any position between both positions. Is done. When the fixing screw 40 is loosened, the tilting plate 39 and, consequently, the blade case 32 can tilt between the right-angle cut position and the tilt cut position.
[0008]
On the back side of the blade case 32, a motor case 35a is attached so as to be vertically movable within a certain range. The drive motor 35 is built in the motor case 35a. The output shaft 37 rotated by the drive motor 35 projects into the blade case 32, and the saw blade 31 is mounted on the projecting portion.
The vertical movement supporting structure of the saw blade 31 and the driving motor 35 with respect to the blade case 32 is a known technique in this type of cutting machine, and does not require any particular change in the present embodiment. When the saw blade 31 and the driving motor 35 are moved to the rising end with respect to the blade case 32 as shown in FIG. 4, the entire saw blade 31 is housed inside the blade case 32, and the lower surface side of the base 2 It does not stick out. On the other hand, when the saw blade 31 and the drive motor 35 are moved to the lower end with respect to the blade case 32, the lower half of the saw blade 31 is projected to the lower surface side of the base 2. The cutting operation can be performed by the cutting machine 1 only in a state where the saw blade 31 is protruded to the lower surface side of the base 2.
The vertical position of the saw blade 31 and the drive motor 35 with respect to the blade case 32 can be fixed at an arbitrary position by tightening a fixing screw 35b, thereby protruding the saw blade 31 toward the lower surface of the base 2. The depth of cut can be adjusted by adjusting the amount.
A handle 36 for an operator to grip is integrally provided on the upper surface side of the motor case 35a. Although not shown, a compression spring is interposed between the cutting machine main body 30 and the blade case 32. The compression spring biases the cutting machine main body 30 in a direction to move upward with respect to the blade case 32. When the operator grips the handle 36 and pushes down the drive motor 35, the saw blade 31 can be displaced downward. When the operator stops the downward pressing operation, the saw blade 31 is returned upward by the compression spring and is housed in the blade case 32.
[0009]
Next, a sub-base 38 is integrally provided at the lower end of the blade case 32 in a state that the sub-base 38 protrudes rearward (to the left in the cutting progress direction). The sub base 38 is provided along the lower end of the blade case 32. The sub base 38 is tilted integrally with the blade case 32. That is, when the saw blade 31 is located at the right-angled cutting position, the sub-base 38 is located substantially in an overlapping state (parallel) with the base 2, and when the saw blade 31 is located at the inclined cutting position, The blade 31 is tilted with respect to the base 2 at the same tilt angle as the blade 31.
The tilting plate 39 is provided at the front end of the sub base 38 in the cutting progress direction so as to rise upward. In FIG. 5, the tilt plate 39 and the tilt support plate 21 are not shown. The tilt stopper device 10 of the present embodiment is provided on the rear side (left side in FIG. 1) of the tilting plate 39 and on the left side in the cutting progress direction with respect to the saw blade 31. The details of the tilt stopper device 10 are shown in FIG. In the present embodiment, the case where the inclination stopper device 10 positions the saw blade 31 at the inclined cutting position inclined by 45 ° in the direction of displacing the upper side of the saw blade 31 rightward in the cutting progress direction from the right-angled cutting position. For example.
[0010]
The inclined stopper device 10 includes a stopper member 11 on the cutting machine main body 30 side and a stopper protrusion 12 on the base 2 side. The stopper member 11 is attached to a tip of the operation lever 13. In the present embodiment, a bolt (screw) is used as the stopper member 11. The operation lever 13 is rotatably mounted on the upper surface of the sub base 38 via the support shaft 14. The operation lever 13 is rotatable in the surface direction of the sub base 38. The rear end of the operating lever 13 is provided with a knob 13a extending upward. The operator can turn the operating lever 13 by manually operating the knob portion 13a. The distal end side of the stopper member 11 protrudes to the lower surface side of the sub base 38 via an insertion groove 38 b provided in the sub base 38. As described above, in the present embodiment, since the bolt is used as the stopper member 11, by adjusting the screwing amount, the angle can be adjusted to make the inclination angle of the cutting machine body 30 accurate.
The insertion groove 38b is formed along an arc centered on the support shaft 14. The insertion groove 38b communicates with a window 38a described later. By rotating the operation lever 13, the stopper member 11 moves between the deep portion (end portion) of the insertion groove portion 38b and the position that has entered the window portion 38a as shown in FIG. Hereinafter, with respect to the position of the stopper member 11, the position at the back of the insertion groove portion 38b is referred to as a non-stopper position, and the position of entering the window portion 38a is referred to as a stopper position.
[0011]
On the other hand, the stopper projection 12 is provided on the upper surface of the base 2 so as to project upward. In the state shown in FIG. 5, the stopper projection 12 protrudes toward the upper surface of the sub base 38 via the window 38a of the sub base 38. A flat stopper receiving portion 12a is provided on the upper end of the stopper projection 12.
The stopper receiving portion 12a is protruded and retracted from the window portion 38a with the tilting operation of the blade case 32 and thus the saw blade 31. That is, the size of the protrusion of the stopper projection 12 toward the upper surface of the sub base 38 increases as the inclination angle of the saw blade 31 decreases (closer to the right-angled cutting position), and increases as the inclination angle increases (closer to the inclined cutting position). When the saw blade 31 is tilted to the inclined cutting position (a position inclined by 45 ° from the right angle cutting position) or to a slightly larger inclination angle than the inclined cutting position, the saw blade 31 does not protrude from the window 38a.
The cutting member main body 30 is tilted to a state where the saw blade 31 is tilted at a tilted cutting position or at a tilt angle larger than this, so that the stopper receiving portion 12a is positioned below the window 38a, so that a stopper member is formed. The operating lever 13 can be turned to the stopper position side without causing the distal end of the actuator 11 to interfere with the stopper receiving portion 12a.
[0012]
Then, in a state where the cutting machine main body 30 is tilted to a state where the saw blade 31 is tilted to a slightly larger tilt angle than the tilt cutting position, the operating lever 13 is rotated to move the stopper member 11 to the stopper position (the window 38a). ), And then slightly return the cutting machine body 30 to the right-angled cutting position side, so that the distal end of the stopper member 11 can be brought into contact with the stopper receiving portion 12a. The tilting toward the right-angle cutting position is restricted, so that the cutting machine body 30 is positioned at the inclined cutting position. With the cutting machine body 30 positioned in this manner, the cutting machine body 30 is fixed at the inclined cutting position by tightening the fixing screw 40.
According to the cutting machine 1 of the present embodiment configured as described above, the stopper member 11 provided on the left side in the cutting direction with respect to the saw blade 31 is provided on the upper surface of the base 2 and also on the left side in the cutting direction. The cutter main body 30 is positioned at the inclined cutting position by contacting the stopper receiving portion 12a. For this reason, even in the cutting machine 1 having the narrow base 2 having no portion corresponding to the range on the right side in the cutting direction with respect to the saw blade 31, the cutting machine main body 30 can be precisely positioned at the inclined cutting position. Can be positioned.
Further, in the case of the present embodiment, since a bolt is used as the stopper member 11, fine adjustment of the tilt stopper position can be performed by adjusting the amount of tightening with respect to the operation lever 13.
[0013]
Various modifications can be made to the embodiment described above. For example, the case where the present invention is applied to the cutting machine 1 having the narrow base 2 is illustrated, but a portion corresponding to a range on the right side in the cutting progress direction with respect to the saw blade (a portion indicated by A in FIGS. 10 and 11). It is needless to say that the present invention can also be applied to a cutting machine having a wide base having
Also, the cutting machine 1 in which the cutting depth is adjusted by moving the drive motor 35 and the saw blade 31 up and down with respect to the blade case 32 has been illustrated, but the drive motor and the motor case are fixed to the back side of the blade case. As a result, the present invention can be similarly applied to a cutting machine in which the saw blade does not move up and down in the blade case but moves up and down integrally with the base to adjust the cutting depth.
Furthermore, although the configuration including one stopper member 11 has been illustrated, it is also possible to provide a plurality of stopper members and thereby to provide an inclined stopper device which can be positioned at a plurality of inclined cutting positions, and a single stopper member. Is movably provided at a plurality of stopper positions, and by providing a plurality of stopper receiving portions on the stopper projections corresponding to the plurality of stopper positions, the cutting machine body and the saw blade can be provided at a plurality of inclined cutting positions (for example, It can be positioned at 30 °, 45 °, 60 ° from the right angle cutting position.
[0014]
FIGS. 6 to 8 show an inclined stopper device 42 according to a second embodiment having two stopper members 44 and 45. The tilt stopper device 42 of the second embodiment includes an operating lever 43 longer than the operating lever 13 of the tilt stopper device 10 of the first embodiment. The operation lever 43 is rotatably mounted on the upper surface of the sub base 38 via a support shaft 46. The two stopper members 44 and 45 are attached to the operating lever 43. Of these two stopper members 44, 45, the stopper member 44 closer to the support shaft 46 is a stopper member for small inclination (hereinafter, referred to as a small inclination stopper member 44), which is attached to the rotation tip side. The stopper member 45 provided is used as a stopper member for large inclination (hereinafter, referred to as a large inclination stopper member 45). As shown in FIGS. 7 and 8, the distal ends of the stopper members 44 and 45 protrude from the lower surface of the sub base 38 through the insertion groove 38 d provided in the sub base 38. The projecting dimension of the small inclination stopper member 44 toward the lower surface side of the sub base 38 is smaller than that of the large inclination stopper member 45. Note that bolts are used for the stopper members 44 and 45 as in the first embodiment described above.
[0015]
In this embodiment, the saw blade 31 is positioned at a position inclined by 45 ° from the right angle cutting position (first inclined cutting position) by the small inclination stopper member 44, and the saw blade 31 is squared by the large inclination stopper member 45. The case where the positioning is performed at a position inclined by 60 ° from the cutting position (second inclined cutting position) will be described.
On the other hand, the stopper projection 47 provided upright on the upper surface of the base 2 has one stopper receiving portion 47a and one escape portion 47b on the upper surface. The stopper projection 47 projects to the upper surface side of the sub base 38 via the window 38c provided in the sub base 38 as described above. The size of the window portion 38c is set to a size that allows the base of the stopper projection 47 to be inserted when the saw blade 31 is positioned at the right-angled cutting position and the sub-base 38 is superimposed on the base 2. ing.
This point is set similarly to the window 38a. As in the first embodiment, the insertion groove 38d communicates with the window 38c.
[0016]
According to the inclined stopper device 42 of the second embodiment provided in this manner, the state where both stopper members 44 and 45 are located at the non-stopper position as shown by the solid line in FIG. In the state of being located in the insertion groove portion 38d), neither of the stopper members 44, 45 comes into contact with the stopper receiving portion 47a, so that the cutting machine main body 30 can be positioned at the right angle cutting position.
When the fixing screw 40 is loosened and the cutting machine main body 30 is tilted to the right in the cutting progress direction, the sub base 38 is tilted integrally with the blade case 32, so that the window 38 c is gradually displaced upward, and accordingly the stopper projection 47 The protruding dimension of the sub base 38 toward the upper surface side gradually decreases. A first stopper in which the cutting lever main body 30 is inserted into the window 38c by rotating the operating lever 43 in a state where the cutting machine main body 30 is inclined from the right-angled cutting position to 45 ° or a slightly larger angle than 45 °. When the cutting machine main body 30 is returned to the right-angled cutting position side in this state, the tip of the small inclined stopper member 44 comes into contact with the stopper receiving portion 47a as shown in FIG. Consequently, the saw blade 31 is positioned at the first inclined cutting position. At this time, the distal end of the large inclination stopper member 45 is located in the relief portion 47b of the stopper projection 47 and is separated from the stopper receiving portion 47a. Therefore, the large inclination stopper member 45 is located at the non-stopper position.
[0017]
The cutter body 30 is further tilted from the first inclined cutting position to be inclined from the right-angled cutting position to an angle slightly larger than 60 ° so that the large inclined stopper member 45 is located at the second stopper position. Can be. When the cutting machine body 30 is returned to the right-angled cutting position in this state, the large inclination stopper member 45 comes into contact with the stopper receiving portion 47a as shown in FIG. 8, whereby the cutting machine body 30 and thus the saw blade 31 are moved to the second position. It is positioned at the inclined cutting position. At this time, the tip of the small inclination stopper member 44 is floating from the stopper receiving portion 47a as shown in the figure.
As described above, according to the inclined stopper device 42 of the second embodiment, the cutting machine main body 30 and, consequently, the saw blade 31 are at a right angle by keeping both the stopper members 44 and 45 at the non-stopper position (in the insertion groove portion 38d). It can be located at the cutting position. The cutting machine main body 30 is tilted from this right-angled cutting position to an angle slightly larger than 45 °, and in this state, the operating lever 43 is rotated to move the small tilt stopper member 44 to the first stopper position. The first inclination in which the cutting machine body 30 and thus the saw blade 31 are inclined by 45 ° from the right-angled cutting position by returning the cutting machine body 30 to the right-angled cutting position side and bringing the small inclined stopper member 44 into contact with the stopper receiving portion 47a. It can be positioned at the cutting position.
Further, the cutting machine main body 30 is tilted from the right-angled cutting position to an angle slightly larger than 60 °, and in this state, the operating lever 43 is further rotated to move the large tilt stopper member 45 to the second stopper position. After the cutting machine body 30 is returned to the right-angled cutting position side and the large inclination stopper member 45 is brought into contact with the stopper receiving portion 47a, the cutting machine body 30 and thus the saw blade 31 are inclined by 60 ° from the right-angled cutting position. It can be positioned at two inclined cutting positions.
[0018]
Also, since the screws are used for both the stopper members 44 and 45 in the inclined stopper device 42 of the second embodiment, the first stopper members 44 and 45 are screwed into the operation lever 43 to adjust the first position. And fine adjustment of the second inclined cutting position can be performed.
The first and second embodiments described above can be further modified. For example, a configuration in which the stopper members 11, 44, 45 are moved to a non-stopper position and a stopper position (first and second stopper positions) by rotating the operation levers 13, 43 via the support shafts 14, 46 is exemplified. However, the stopper member may be moved by sliding the operation lever instead of rotating the operation lever.
Further, although a configuration in which a screw is used for the stopper members 11, 44, and 45 has been exemplified, a pin may be used, or a projection may be provided on the lower surface side of the operating levers 13, 43 to serve as a stopper member.
Furthermore, the configuration in which the right angle cutting position and the inclined cutting position are positioned by moving the stopper member side or the plurality of inclined cutting positions are positioned has been exemplified. Alternatively, the same positioning can be performed by movably providing between a plurality of stopper positions.
In addition, the inclined stopper devices 10 and 42 exemplified above have the function of positioning the cutting machine body and the saw blade at the inclined cutting position. In addition, the inclination stopper devices 10 and 42 can be positioned at the right angle cutting position. it can.
[0019]
Further, in the first and second embodiments described above, as shown in FIG. 1, the drive motor 35 and the handle 36 are provided on the blade case 32 on the left side in the cutting progress direction, and the operator holds the handle 36 with the right hand. Although a general cutting machine 1 (portable circular saw) in a form of performing a cutting work (right hand holding type) has been illustrated, in recent years, along with diversification of the cutting work form, a side opposite to FIG. On the other hand, there is also provided a left-handed type portable circular saw provided with a motor housing and a handle on the right side in the cutting direction. In this portable hand tool of the left-hand holding type, the cutting machine body is located between a right angle position where the saw blade is perpendicular to the base and an inclined position where the upper side of the saw blade is inclined in a direction displacing the upper side of the saw blade to the left in the cutting progress direction. Can be tilted.
The same operation and effect can be obtained by providing the inclined stopper devices 10 and 42 of the above-described first or second embodiment on the right side in the cutting progress direction also for such a left-hand-hold type portable saw. The tilt stopper device in the left hand-held type portable mallet corresponds to an embodiment of the invention described in claim 4.
