As shown in FIGS. 1 and 2, in the measuring device 10 of the embodiment, the taper shank 14 as a connecting portion is rotatably supported on the base 12 having the legs 11 for installation with respect to the station via the bracket 13. Then, the measuring device 10 is gripped by the spindle of the machine tool at the taper shank 14 and moved to a required position. When the main shaft is rotated, only the taper shank 14 is idled, and the other parts of the measuring device 10 are not rotated. Further, in drawings other than FIG. 1, the taper shank 14 is not shown.

As shown in FIGS. 2 to 4, four columns 15 are erected and fixed on the upper surface of the base 12. A measuring mechanism 16 for measuring the upright surface is supported at the upper end of the support column 15. The measuring mechanism 16 and its related configurations will be described in detail below.

That is, as shown in FIGS. 3 to 5 and 8, a stepped bolt 22 is screwed into the screw hole 21 at the upper end of the support column 15, and the stepped bolt 22 is in the form of rubber such as urethane rubber. An elastic receiving member 23 as a cushioning means made of an elastic material is externally fitted, and the elastic receiving member 23 is supported on the upper end surface of the support column 15 via a collar 24 and a washer 25. A mounting member 27 having a substantially triangular plane is fixed to the upper surface of the four corners of the square frame-shaped support frame 26, and the downward mounting recess 28 of the mounting member 27 is fitted to the elastic receiving member 23 from the upper side. At the same time, the flange portion 29 at the upper end of the mounting recess 28 is placed on the upper surface of the elastic receiving member 23. Therefore, the support frame 26 is mounted and supported on the elastic receiving member 23 via the mounting member 27, and the support frame 26 is X in one plane (for example, a horizontal plane) within the range of elastic deformation of the elastic receiving member 23. It can be moved in the axial direction, the Y-axis direction, and the combined direction in both axial directions.

As shown in FIGS. 1, 6 and 9, a pedestal 32 located in an area surrounded by the four columns 15 is fixed to the support frame 26 via a pair of suspension plates 31 in a suspended state. Has been done. As shown in FIG. 8, a first guide member 33 is fixed to the upper surface of the cradle 32, and both sides thereof are lower guide surfaces 331 extending in one direction (in the X-axis direction in the embodiment). The first guide member 33 supports a first slider 34 that can move in the X-axis direction along the lower guide surface 331, and the second guide member 36 is mounted on the upper surface thereof via the lower interposition plate 35. There is. The second guide member 36 is formed with an upper guide surface 361 extending in another direction (in the Y-axis direction in the embodiment) perpendicular to the lower guide surface 331 of the first guide member 33. A second slider 37 is movably supported on the upper surface of the second guide member 36 along the upper guide surface 361 in the Y-axis direction.

As shown in FIGS. 8 and 9, a pivot support plate 39 as a support member is fixed to the upper surface of the second slider 37 via an upper interposition plate 38, and the pivot support plate 39 has a support hole 40. It is formed. Therefore, the pivot support plate 39 moves in the X-axis direction, the Y-axis direction, and the combined direction thereof in a plane parallel to the moving direction of the support frame 26 by the guiding action of the first and second guide members 33, 36. It is possible. The members on the upper side of the cradle 32, that is, the first guide member 33, the first slider 34, the lower interposition plate 35, the second guide member 36, the second slider 37, the upper interposition plate 38, and the pivot support plate 39. A guide stage mechanism 85 as a slide mechanism is formed.

As shown in FIGS. 4, 5 and 10, fixed members 41 and movable members 42 are provided facing each other on the lower surfaces of the two adjacent sides of the support frame 26, respectively. Both fixing members 41 are fixed to the support frame 26, and both movable members 42 are in the X-axis direction and the Y-axis direction, which are the protruding directions toward the opposite fixing members 41 by the springs 43 as the holding means and the urging means, respectively. Is being moved to. Then, in a state where a predetermined width interval 44 is formed between the two members 41 and 42, the stop portion 47 prevents the movable member 42 from protruding.

A pair of arms 45 are fixed to the upper interposition plate 38 at an angular interval of 90 degrees, and rollers 46 are supported at the tips thereof. Both rollers 46 are located within the distance between the two rollers 46, respectively. Therefore, the movement of the upper interposition plate 38 and the pivot support plate 39 of the guide stage mechanism 85 in the measurement mechanism 16 is restrained within the range of the elastic force of the spring 43 and the elastic receiving member 23, and the pivot support plate 39 is restrained. Is provided with an elastic force that resists movement in the X-axis direction and the Y-axis direction by the spring 43. Therefore, the spring 43 elastically holds the pivot support plate 39 in place.

As shown in FIGS. 5, 8, 9 and 10, a support block 51 is fixed to the upper surface of each of the two adjacent sides of the support frame 26, and a fulcrum pin 53 is inserted into the screw hole 52 of the support block 51. Is screwed in the screw portion 54. Each of the fulcrum pins 53 is located on one axis in the X-axis direction and one axis in the Y-axis direction on the same surface, extends outward, and a spherical portion 55 is formed at the tip thereof. Therefore, when a large force acts on the spherical surface portion 55, the fulcrum pin 53 is moved together with the support frame 26 due to the elastic deformation of the elastic receiving member 23.

As shown in FIGS. 4, 6, 7, and 9, the suspension support plate 63 is fixed to the upper surface side of the upper interposition plate 38 by bolts 62 while maintaining the vertical distance by the collar 61. There is. A lower pin 64 composed of four stepped screws is projected and fixed upward to the suspension support plate 63.

A suspension plate 65 is arranged on the suspension support plate 63, and stays 66 are fixed to the stays in an upright state at four corners thereof, and the stays 66 face the lower pins 64 at intervals. The upper pin 67 is projected and fixed downward. A spring 70 as a spring means is fitted onto the upper and lower pins 64 and 67, and the spring 70 is formed between the support nut 68 on the threaded portion of the lower pin 64 and the bent portion 69 at the upper end of the stay 66. It is intervened between them. As a result, the suspension plate 65 is suspended on the spring 70 via a stay 66, and is elastically supported by the spring 70 in an elastic suspended floating state (hereinafter, simply referred to as a floating state). Therefore, the suspension plate 65 can be tilted in all directions within the elastic range of the spring 70. Here, the floating state refers to a state in which the floating state is supported by an elastic member such as a spring 70 so as to be tiltable, as described above.

As shown in FIG. 9, the suspension support plate 63 is formed with a free insertion hole 77 facing the support hole 40 of the pivot support plate 39. Further, a regulation pin 81 is fixed to the suspension support plate 63, and the regulation pin 81 is inserted into the large regulation hole 82 of the suspension plate 65 so as to be relatively movable. Therefore, the suspension plate 65 can move with respect to the suspension support plate 63 in a floating state within the clearance range between the regulation pin 81 and the regulation hole 82, but further movement is restricted. ..

As shown in FIG. 9, a pivot 76 as a connecting means is screwed into the screw hole 75 of the hanging plate 65 at the screw portion thereof. The pivot 76 is loosely inserted into the free insertion hole 77 of the suspension support plate 63. On the other hand, inside the support hole 40 of the pivot support plate 39, a ball member 78 also as a connecting means is rotatably supported in all directions via the concave spherical surface 80 of the holding member 79, and the pivot 76 is formed in the central hole thereof. The lower end of the is slidably inserted in its axial direction. Therefore, under the action of the spring force of the spring 70, the suspension plate 65 rotates the ball member 78 and moves the pivot 76 in the axial direction around the center of the ball member 78, and in the guide stage mechanism 85. It can tilt in all directions with at least one slide movement in the X-axis direction and the Y-axis direction. Reference numeral 83 denotes a member for regulating an excessive inclination of the hanging plate 65.

As shown in FIGS. 2 and 9, the tray plate 72 is fixed to the upper surface side of the suspension support plate 63 via the spacer 71. The tray plate 72 constitutes a mounting portion of the spirit level 91, and the spirit level 91 is mounted on the upper surface of the tray plate 72. Then, when the spirit level 91 is tilted and rotated in a plane in the vertical direction passing through the X axis, it detects its own tilt angle and outputs the detection data to an external device (not shown). As shown in FIG. 1, the spirit level 91 has a display unit 92 on its upper surface, and the display unit 92 visually displays the tilt angle by the position of a bubble or a pendulum or a digital display.

As shown in FIGS. 2, 10, 11 and 12, the tray plate 72 and its tray plate 72 were fixed at positions facing the both fulcrum pins 53 on the X-axis direction line and the Y-axis direction line, respectively. On the side surface of the bracket 93, contact blocks 94 and 95 having a flat rectangular cross section extended in the vertical direction are supported and fixed. Measurements in which the front side surfaces of the upper and lower ends of the contact blocks 94 and 95 and the side surfaces on both sides thereof (the front side surfaces are referred to as front surfaces) are in contact with the guide surfaces 113 and 114, which are the surfaces to be measured, respectively. It has surfaces 941,951 and regulatory surfaces 942,952 that are adjacent to the measurement surfaces 941,951 and face different angles (90 degrees). Both measurement surfaces 941 of the contact block 94 are formed in parallel.

Then, as shown in FIG. 10, the contact block 94 facing the fulcrum pin 53 on the Y-axis direction axis has measurement surfaces 941 on both side surfaces, and the regulation surface 942 is arranged on the front surface between the measurement surfaces 941. Has been done. The contact block 95 facing the fulcrum pin 53 on the X-axis direction axis has a regulation surface 952 on both side surfaces and a measurement surface 951 on the front surface between the regulation surfaces 952. Therefore, the measurement surfaces 941 and 951 of both contact blocks 94 and 95 are located in the plane orthogonal to the X-axis direction.

A hole-shaped fulcrum portion 98 having an entrance portion as a tapered guide portion is formed on the inner side surfaces of both contact blocks 94 and 95, and the fulcrum portion 98 is formed on the X-axis direction axis and the Y-axis direction axis. It faces the spherical surface portion 55 of the fulcrum pin 53. The inner diameter of the fulcrum portion 98 is slightly larger than the outer diameter of the spherical portion 55, and the suspension plate 65 moves in the X-axis direction or the Y-axis direction together with the suspension support plate 63, so that the fulcrum portion 98 becomes a spherical portion. It is engaged with the 55 in a fitted state, and the spherical portion 55 is brought into contact with the bottom of the fulcrum portion 98.

Next, the operation of the measuring device 10 of the present embodiment will be described.
As described above, the measuring device 10 is gripped by the spindle of the machining center at the taper shank 14, and for example, in the column 110 of the machine tool shown in FIGS. 11 and 12, a pair of guide portions 111 extending in the vertical direction, The inclination angles of the adjacent first and second guide surfaces 113 and 114 are measured at a 90 degree angle of 112. In FIGS. 11 to 14, the first guide surfaces 113 of the left and right guide portions 111 and 112 face each other, and the second guide surfaces 114 face the front.

In the standby state in which the measuring device 10 is not performing the measuring operation, as shown in FIGS. 5 and 10, the roller 46 is elastic due to the urging force of the spring 43 within the distance 44 between the fixed member 41 and the movable member 42. The guide stage mechanism 85, which is sandwiched and has the pivot support plate 39, is held in a neutral position. Therefore, the suspension support plate 63 is held in the neutral position via the bolt 62 and the collar 61. Further, the pivot 76 is elastically held in a neutral upright position, so that the hanging plate 65 and the tray plate 72 having the contact blocks 94 and 95 are also held in the neutral position. Therefore, the contact blocks 94 and 95 are separated from the spherical surface portion 55 with the fulcrum portion 98 facing the spherical surface portion 55 of the fulcrum pin 53.

In this state, the measurement of the inclination angles of the first and second guide surfaces 113 and 114, which are the upright surfaces of both guide portions 111 and 112 of the column 110, is performed as follows.
That is, FIGS. 13 (a) and 13 (b) show a case where the inclination angle of the second guide surface 114 of the guide portions 111 and 112 is measured, respectively. As shown in FIG. 13A, when measuring the inclination angle of the second guide surface 114 of one guide portion 111, the measuring device 10 supported by the spindle is moved by the movement of the spindle of the machining center to guide the guide portion 111. Moved towards.

In this case, due to the movement of the spindle, the measurement surface 951 of one of the contact blocks 95 of the measuring device 10 is directed to the second guide surface 114, and the one regulating surface 952 of the contact block 95 is the first. The orientation of the measuring device 10 is set so as to be directed to the guide surface 113. In this state, the measuring device 10 is moved in the X-axis direction toward the guide portion 111 so that the measuring surface 951 of the contact block 95 faces the second guide surface 114 of the guide portion 111. Therefore, the measurement surface 951 comes into contact with the second guide surface 114.

After this contact, the base 12 is moved in the Y-axis direction toward the first guide surface 113 of the guide portion 111 by continuing the movement of the spindle.
Therefore, the fulcrum pin 53 approaches the fulcrum portion 98 of the contact block 95 while sliding the guide stage mechanism 85 in both the X and Y axial directions. Then, when one of the rollers 46 comes out of the gap 44 between the fixed member 41 and the movable member 42, the pivot support plate 39 can move freely together with the pivot 76. Therefore, the contact block 95 can move with almost no resistance according to the inclination of the second guide surface 114, and the measurement surface 951 of the contact block 95 is in a state of being along the second guide surface 114. Further, the regulation surface 952 of the contact block 95 abuts on the first guide surface 113 to regulate the position.

In this way, the spherical portion 55 of the fulcrum pin 53 is fitted to the fulcrum portion 98. Here, the contact blocks 94 and 95 are supported by a hanging plate 65 that is floating in a state where an elastic force is applied by a spring 70. Therefore, the measurement surface 951 of the contact block 95 is pressed against the second guide surface 114, and the measurement surface 951 has an angle along the second guide surface 114. Further, one of the regulating surfaces 942 of the contact block 94 is pressed against the first guide surface 113.

Therefore, by pressing the regulation surface 952 against the first guide surface 113, the rotation of the suspension plate 65, the tray plate 72, and the level 91 about the X axis shown in FIG. 10 is restricted. On the other hand, when the measurement surface 951 of the contact block 95 is pressed against the second guide surface 114 and the second guide surface 114 is inclined, the hanging plate 65, the tray plate 72, and the level 91 It is rotated in a plane passing through the X axis together with the contact block 95 according to the inclination angle of the second guide surface 114. At this time, the guide stage mechanism 85 is slid to allow tilting of the spirit level 91 or the like via the pivot 76. In this way, the inclination angle of the second guide surface 114 is measured by the spirit level 91 mounted on the tray plate 72 on the suspension plate 65.

When the pressing force by the spindle is strong and a large reaction force is received from the contact block 95 side with respect to the hanging plate 65 and the tray plate 72, the elastic receiving member 23 made of a rubber material bends to support the frame. When 26 escapes, this reaction force is absorbed.

When the measurement of the second guide surface 114 is completed, the spindle moves backward in the reverse order of the start of measurement. Therefore, as the base 12 side retracts, the rollers 46 move within the interval 44 in the reverse order of the above. Return and move. Then, the fulcrum pin 53 retracts from the fulcrum portion 98 of the contact blocks 94 and 95 and returns to the state shown in FIG.

As shown in FIG. 13 (b), when measuring the inclination angle of the second guide surface 114 of the guide portion 112 on the opposite side, the moving direction of the measuring device 10 is symmetrical with that in the case of FIG. 13 (a). At the same time, the regulation surface 952 regulated by the second guide surface 114 is on the opposite side in the case of FIG. 13A. This point is different from the case of FIG. 13A, but the other operations are the same as the case of the measurement of the second guide surface 114 of the guide unit 111.

As shown in FIG. 13C, when measuring the inclination angle of the first guide surface 113 of the guide portion 111, the regulation surface 942 on the front side of the contact block 94 is directed to the second guide surface 114, and the inclination angle is directed to the second guide surface 114. The measurement surface 941 on one side surface is directed toward the first guide surface 113. Then, after moving the measuring device 10 so that the regulation surface 942 of the contact block 94 aims at the second guide surface 114 of the guide portion 111, the measuring device 10 aims at the measuring device 10 and the measuring surface 941 aims at the first guide surface 113. To move.

That is, in this case, as is clear from FIG. 13 (c), the orientation of the entire measuring device 10 is changed by 90 degrees from the cases of FIGS. 13 (a) and 13 (b). Then, in this state, the regulation surface 942 on the front surface of the contact block 94 is pressed against the second guide surface 114, and then one of the measurement surfaces 941 is pressed against the first guide surface 113. Also in this case, the base 12 is moved while the guide stage mechanism 85 slides, and the fulcrum portion 98 of the contact block 94 engages with the spherical portion 55 of the fulcrum pin 53. Therefore, in a state where the tilt of the suspension plate 65 and the level 91 is restricted by the regulation surface 942 of the contact block 94, the suspension plate 65 and the level 91 together with the contact block 94 are the fulcrum pin 53 and the spherical portion 55. It is in a state of being tilted about the Y axis of FIG. 10 passing through the engaging portion with the above, and the tilt angle of the first guide surface 113 can be measured by this tilting.

As shown in FIG. 13D, when measuring the inclination angle of the first guide surface 113 of the other guide portion 112 in the same manner as described above, the first guide is measured by the other measuring surface 941 of the contact block 94. The surface 113 is measured.

As described above, as shown by the alternate long and short dash line in FIG. 11, if the inclination angles of the upper and lower multiple positions such as the upper and lower two positions of the first and second guide surfaces 113 and 114 are measured, the entire guide surfaces 113 and 114 can be measured. Can recognize the tilt angle of.

As is clear from FIGS. 14 (a) and 14 (b), the contact blocks 94 and 95 of the embodiment have a flat cross section. Therefore, when a reaction force acts on the contact blocks 94 and 95 from the direction intersecting the flat direction due to the pressing action due to the movement of the spindle, unlike the case shown by the two-dot chain line in FIG. 14B, It is possible to prevent the contact block from rolling over, and it is possible to measure the inclined surface without any trouble.

The measuring device 10 of the first embodiment that operates as described above can obtain the following effects.
(1) A spirit level 91 is mounted on a tray plate 72 held in a floating state by a spring 70, and a contact block 94 abutting on the upright guide surfaces 113 and 114 is mounted on the tray plate 72. , 95 are provided. Therefore, if the contact blocks 94 and 95 are applied to the first and second guide surfaces 113 and 114, the inclination angle of the guide surfaces 113 and 114 can be measured without causing the guide surfaces 113 and 114 to fall down. Therefore, the inclination angles of the guide surfaces 113 and 114 can be measured easily and accurately.

Moreover, since both measurement surfaces 941 of the contact block 94 are formed in parallel, the parallelism between the guide surfaces 113 is measured by measuring each of the guide surfaces 113 of the guide portions 111 and 112 by both measurement surfaces 941. Can be confirmed. That is, if the inclination angles of the guide surfaces 113 are equal, the guide surfaces 113 are parallel.

(2) The contact blocks 94 and 95 are provided with regulatory surfaces 942 and 952 adjacent to the measurement surfaces 941 and 951 and facing in a direction different from that of the measurement surfaces 941 and 951. Therefore, if the regulation surfaces 942 and 952 are applied to the guide surfaces 113 and 114 adjacent to the guide surfaces 113 and 114 to be measured, the level 91 on the tray plate 72 can regulate the operation other than the operation for measurement. , The inclination angles of the upright guide surfaces 113 and 114 can be accurately measured.

(3) Two contact blocks 94 and 95 are provided. In one contact block 94, both side surfaces are measured on the measurement surface 941, the front surface is on the regulation surface 942, and in the other contact block 95, the front surface is measured. Both sides of the surface 951 are regulated surfaces 952. Therefore, the inclination angles of the first and second guide surfaces 113 and 114 of both guide portions 111 and 112 can be measured by one spirit level 91. Therefore, the entire device can be made compact.

(4) By holding the roller 46 by a pair of springs 43, it is possible to prevent the contact blocks 94 and 95 from being delusional until the contact blocks 94 and 95 come into contact with the guide surfaces 113 and 114. Therefore, the inclination angles of the guide surfaces 113 and 114 can be smoothly measured.

(5) The base 12 is provided with a fulcrum pin 53, and the contact blocks 94 and 95 are provided with a fulcrum portion 98 that engages with the spherical portion 55 at the tip of the fulcrum pin 53 by moving the support frame 26. ing. Then, since the contact blocks 94 and 95 are tilted around one point formed by the engaging portion between the spherical surface portion 55 and the fulcrum portion 98, the tilt angle of the guide surfaces 113 and 114 can be accurately measured.

(6) An elastic receiving member 23 for buffering an excessive force acting on the fulcrum pin 53 is provided between the support frame 26 for supporting the fulcrum pin 53 and the base 12. Therefore, accurate measurement of the guide surfaces 113 and 114 can be performed by avoiding vibration and impact acting on the fulcrum pin 53 and the support frame 26 via the contact blocks 94 and 95.

(7) Since the base 12 is provided with the taper shank 14, the measuring device 10 can be operated by using a spindle such as a machining center. Therefore, a dedicated device for operating the measuring device 10 for measurement is not required.
