Has been.

  The horizontal polishing unit 6 is provided in one of the pair of horizontal transmission modules 53 and is connected to the horizontal grinding wheel 61 having an axle parallel to the left-right direction Y and the horizontal grinding wheel 61 so that the horizontal grinding wheel 61 can be driven to rotate. The horizontal drive module 62 is provided.

  In this example, the horizontal drive module 62 protrudes further to the right from one of the pair of horizontal transmission modules 53, for example, from the lower end of the side surface of the horizontal moving base 534 of the horizontal transmission module 53 on the right side in the left-right direction Y of FIG. Although it is formed in a cylindrical shape, it may be provided on the horizontal moving base 534 of the other horizontal transmission module 53 on the left side in the left-right direction Y as necessary.

  When the horizontal grinding wheel 61 is rotationally driven by the horizontal drive module 62, the horizontal grinding wheel 61 rotates about a horizontal axis L2 (see FIG. 5) parallel to the left-right direction Y. It is known in the art that the horizontal grinding wheel 61 is rotationally driven by the horizontal drive module 62 as a polishing means, and the details thereof are omitted here.

  For example, the workpiece 9 is formed in a convex shape on the right side in FIG. 5 while being spaced apart in the vertical direction Z so as to define two rail grooves 91, 91 that are recessed in the left-right direction and have a concave shape. There are two rail walls 92. Further, since the convex rail wall 92 is formed in the same manner on the left side in the left-right direction Y in FIG. 5, the two rail grooves 91, 91 described above have two rails on the opposite side in the left-right direction Y. Grooves 91, 91 are defined. Here, each rail groove 91 extends in the feed direction X as shown in FIG.

  The vertical grinding wheel 51 is moved along the left-right direction Y by the horizontal transmission module 53, enters the corresponding rail groove 91 of the workpiece 9 and is ground, and the horizontal grinding wheel 61 is moved along the vertical direction Z. And it arrange | positions so that it may grind in contact with the upper surface of the uppermost rail wall 92 of the up-down direction Z.

Next, the operation and action of the polishing processing apparatus configured as described above will be described.
The workpiece 9 is mounted on the polishing processing apparatus according to this example using a magnetic attractive force, and the first drive motor 421 is operated to rotate the first guide screw shaft 422. When the first guide screw shaft 422 rotates, the first screw nut member 423 formed coaxially with the first guide screw shaft 422 is interlocked. Since the fitting end 42 a of the first screw nut member 423 is connected to the fitting hole 42 b of the moving beam member 41, the moving beam member 41 moves along the first rail portion 425 by the movement of the single axis transmission module 42. Are moved in the vertical direction Z. Then, the vertical grinding wheels 51 are simultaneously moved to the same height corresponding to the rail grooves 91 on both sides of the workpiece 9 in cooperation with each other. That is, since the moving beam member 41 can move in the vertical direction Z by the movement of the single-axis transmission module 42 as described above, in addition to the rail groove 91 formed on the lower side, the rail groove 91 formed on the upper side. Can also be moved (FIG. 7).

  Further, the second drive motor 531 is operated to rotate the second guide screw shaft 532. When the second guide screw shaft 532 rotates, the second screw nut member 533 is interlocked. Due to the movement of the second screw nut member 533, the horizontal moving table 534 moves in conjunction with the second rail portion 536 along the left-right direction Y. Then, the vertical grinding wheel 51 moved to the same height moves so as to enter the rail grooves 91 on both sides of the workpiece 9, as shown in FIG.

  Thus, the feed module 22 on which the workpiece 9 is mounted is moved along the feed direction X under the control of a control unit (not shown). As shown in FIG. 5, the vertical grinding wheel 51 moved to the same height moves in the left-right direction Y and approaches the feed module 22 so that the rail grooves 91 on both sides of the workpiece 9 are moved. The groove bottom surfaces of the rail grooves 91 of the workpiece 9 are respectively ground and ground.

  As shown in FIGS. 4, 7, and 8, when grinding the upper surface of the upper rail wall 92 in the vertical direction Z of the workpiece 9, first, the second drive motor 531 is operated to perform the second operation. When the guide screw shaft 532 is rotated, the second guide screw shaft 532 is moved away from the feed module 22 along the left-right direction Y, and the vertical grinding wheel 51 is detached from the rail groove 91. When the pair of vertical grinding wheels 51 are driven to move by the first drive motor 421, for example, as shown in FIG. When the horizontal grinding wheel 61 is driven to move by operating the first drive motor 421 and the second drive motor 531, the horizontal grinding wheel 61 moves up and down the workpiece 9 as shown in FIG. 8. Move until it touches the top of direction Z. The horizontal drive module 62 moves the feed module 22 on which the workpiece 9 is mounted along the feed direction X when the horizontal grinding wheel 61 is rotationally driven. While the feed module 22 is moving, the upper surface of the uppermost rail wall 92 in the vertical direction Z of the workpiece 9 is ground by the horizontal grinding wheel 61 that is in contact with the workpiece 9.

  In the present example, the workpiece 9 has been described by taking, for example, a linear rail. However, the workpiece 9 may be any one for grinding both side portions in the left-right direction Y.

  The polishing apparatus according to the present invention can simultaneously move the pair of vertical grinding wheels 51 along the vertical direction Z by one moving beam member 41. Thereby, since the position in the height direction when the pair of vertical grinding wheels 51 moves can be moved without variation, both sides in the left-right direction Y of the workpiece 9 can be ground at the same height. it can. Therefore, the processing accuracy of the workpiece 9 can be improved. Further, the polishing apparatus according to the present invention does not need to provide the vertical slider 162, and the number of members can be reduced, so that the manufacturing cost can be reduced. Further, the horizontal polishing unit 6 can further increase another direction of polishing, so that the convenience of use can be enhanced. Further, since the pair of support columns 31 and the connecting beam 32 are integrally formed in a U shape, they can be attached with high accuracy. Therefore, the grinding accuracy can be improved.

  As described above, in the polishing apparatus according to the present invention, the pair of support columns 31 and the connecting beam 32 are integrally formed in a U shape, and a pair of vertical grinding wheels 51 are formed by one moving beam member 41. Can be moved along the vertical direction Z at the same time, so that it can be attached with high accuracy and the workpiece 9 can be ground at the same height. Therefore, the processing accuracy of the workpiece can be improved.

  As mentioned above, although preferred embodiment of this invention was described, this invention is not limited to this, It cannot be overemphasized that it can change variously in the range which does not deviate from the summary.

  The polishing apparatus according to the present invention is useful for a polishing apparatus that improves the processing accuracy of a workpiece.
