[0017] The bottom of the fixing cylinder 151 and the bottom of the threaded connecting rod 152 are both fixedly connected to the top of the base 11 , the bottom of the positioning rod 19 is fixedly connected to the top of the base 11 , and the inner wall of the lower pressing plate 16 is slidably connected to the outer wall of the threaded connecting rod 152 .

[0018] The positioning device 2 includes an old guide rail 21, a sliding hole 22 is provided in the wall of the old guide rail 21, a limiting hole 23 is provided in the wall of the old guide rail 21, connecting grooves 24 are provided on both sides of the old guide rail 21, connecting holes 25 are provided on the side walls at both ends of the old guide rail 21, and a grinding guide rail 26 is slidably connected to the top of the old guide rail 21. The inner wall of the old guide rail 21 is slidably connected to the outer wall of the fixing screw 12 through the sliding hole 22, the inner wall of the old guide rail 21 is slidably connected to the outer wall of the limiting rod 14 through the limiting hole 23, and the outer wall of the grinding guide rail 26 is slidably connected to the outer wall of the lower pressing plate 16 through the extrusion groove 18. Since the guide opening angle of the old guide rail 21 itself is ninety degrees, and the corner position of the outside of the grinding guide rail 26 is also ninety degrees, the corner position of the grinding guide rail 26 is placed at the guide position of the old guide rail 21, thereby ensuring the guide of the grinding guide rail 26 The side wall of the rail is kept relatively parallel to the bottom of the tooling, and a hole is opened in the old guide rail 21. By opening a sliding hole 22 and a limiting hole 23, the old guide rail 21 is inserted into the limiting rod 14 and the fixing screw 12, and then the extrusion ring 13 is rotated to drive the extrusion ring 13 to extrude the positioning device 2, so that the positioning device 2 is squeezed and positioned by the extrusion ring 13 and the anti-warping device 4. At this time, the horizontal radial movement limit of the positioning device 2 is completed, and the lower pressure plate 16 is lifted. Then, the limiting ring 153 is controlled to be pressed down by the adjusting device 15 to fix the lower pressure plate 16. In the process of fixing the lower pressure plate 16, since the position of the threaded connecting rod 152 is fixed, and the lower pressure plate 16 is limited by the anti-detachment bolt 154 between the fixing tube 151 and the anti-detachment bolt 154, the positioning device 2 can be squeezed by the extrusion groove 18 of the lower pressure plate 16 by rotating the limiting ring 153.

[0019] Example 2: Please refer to Figure 1 - Figure 7The present invention provides a technical solution: on the basis of the first embodiment, the anti-slip device 3 includes a fixing plate 31, and the two sides of the fixing plate 31 are fixedly connected to the positioning plate 32, the outer wall of the positioning plate 32 is fixedly connected to the connecting block 33, the inner wall of the connecting block 33 is rotatably connected to the rotating shaft 34, the outer wall of the rotating shaft 34 is rotatably connected to the limiting plate 35, the inner wall of the limiting plate 35 is slidably connected to the latch 36, the outer wall of the positioning plate 32 is slidably connected to the outer wall of the old guide rail 21 through the connecting groove 24, the outer wall of the latch 36 is slidably connected to the inner wall of the positioning plate 32, the old guide rail 21 is inserted into the positioning plate 32 on the fixing plate 31 through the connecting groove 24, and the positioning plate 32 blocks the old guide rail 21 The block reduces the influence of the axial stress generated during the processing on the support device 1, thereby preventing the fixing screw 12 and the limit rod 14 from bending under long-term pushing. After installing the grinding guide rail 26, rotate the limit plate 35 to make it rotate around the rotating shaft 34 on the connecting block 33 until the limit plate 35 is in contact with the end face of the grinding guide rail 26, and then insert the pin 36. The pin 36 enters the connecting hole 25 of the old guide rail 21 through the limit plate 35. Since the vibration direction generated by the grinding guide rail 26 during the grinding process is perpendicular to the contact surface of the limit plate 35, and the moving direction of the limit plate 35 is limited by the rotating shaft 34, at the same time, the limit plate 35 is difficult to be shaken open under the limitation of the pin 36.

[0020] The anti-warping device 4 includes a support seat 41, the outer wall of the support seat 41 is fixedly connected with a reinforcing rib 42, the outer wall of the support seat 41 is fixedly connected with a fixing block 43, an insertion groove 44 is provided in the wall of the fixing block 43, the outer wall of the support seat 41 is fixedly connected with an extrusion strip 45, and a limiting groove 46 is provided in the wall of the extrusion strip 45. The bottom of the support seat 41 is fixedly connected to the top of the base 11, the outer wall of the fixing block 43 is slidably connected to the outer wall of the anti-warping block 17 through the insertion groove 44, and the outer wall of the extrusion strip 45 is slidably connected to the outer wall of the grinding guide rail 26 through the limiting groove 46. The lower pressing plate 16 is controlled to position and fix the grinding guide rail 26. During the pressing process, the lower pressing plate 16 moves along the positioning rod 19 to the base 11 Move until it is blocked by the fixed cylinder 151. During this process, the anti-warping block 17 under the lower pressure plate 16 gradually approaches the fixed block 43 on the support seat 41 and is gradually inserted into the insertion groove 44 on the fixed block 43. Since the connection controlling the movement of the lower pressure plate 16 is located in the middle position of the lower pressure plate 16, in order to avoid warping at both ends of the lower pressure plate 16, anti-warping blocks 17 are set at both ends to interact with the fixed block 43 through the insertion groove 44. When the grinding guide rail 26 is performing a grinding operation, the grinding process is prone to vibration, causing the two ends of the lower pressure plate 16 to warp up, and the friction generated by the anti-warping block 17 and the fixed block 43 can offset the force generated by the vibration, thereby preventing the two ends of the lower pressure plate 16 from warping due to long-term operation.

[0021] Working principle: When in use, a supporting device 1 and a positioning device 2 are provided so that the self-made tooling has a certain grinding accuracy. The old guide rail 21 that is no longer in use is removed for use. Since the guide rail opening angle of the old guide rail 21 itself is ninety degrees, and the corner position of the outside of the grinding guide rail 26 is also ninety degrees, the corner position of the grinding guide rail 26 is placed at the guide rail position of the old guide rail 21, thereby ensuring that the guide rail side wall of the grinding guide rail 26 remains relatively parallel to the bottom of the tooling. A hole is opened in the old guide rail 21, and the old guide rail 21 is inserted into the limiting rod 14 and the fixing screw 12 by opening a sliding hole 22 and a limiting hole 23. Then, the extrusion ring 13 is rotated to drive the extrusion ring 13 to squeeze the positioning device 2, so that the positioning device 2 is squeezed and positioned by the extrusion ring 13 and the anti-warping device 4. At this time, the horizontal positioning device 2 is completed. The radial movement is limited, the lower pressure plate 16 is lifted, and then the limiting ring 153 is controlled to be pressed down by the adjusting device 15 to fix the lower pressure plate 16. In the process of fixing the lower pressure plate 16, since the position of the threaded connecting rod 152 is fixed, and the lower pressure plate 16 is limited by the anti-slip bolt 154 between the fixing tube 151 and the anti-slip bolt 154, by rotating the limiting ring 153, the extrusion groove 18 of the lower pressure plate 16 can squeeze the positioning device 2, thereby completing the vertical radial movement limit of the positioning device 2, and completing the axial movement limit of the positioning device 2 through the anti-slip device 3. At this time, the positioning device 2 is fixed as a whole, and when the operator performs a grinding operation on the grinding guide rail 26, the use of a trimmer can more easily ensure the guide rail accuracy of the grinding guide rail 26 after trimming.

[0022] The self-made tooling has a simple structure and a certain degree of precision. Due to its simple structure and easy access to materials, the manufacturing and maintenance costs of the tooling are low. Since no complicated processes and expensive materials are required, the production investment is also reduced. At the same time, the simple structure also makes it more convenient for the staff to operate the tooling, so that the operators can quickly get started, thereby reducing training time and costs. At the same time, on the basis of a simple structure, combined with the precision of the guide rail itself, when the tooling is positioned to grind the guide rail 26, the surface to be grinded of the guide rail 26 remains horizontal, so that the staff can accurately handle the worn parts of the guide rail, thereby improving the flatness and straightness of the guide rail, so that the polished guide rail can continue to be used by the equipment. In the repair of machine tool guide rails, it can effectively reduce processing errors, improve product quality, and extend the service life of the guide rails and related equipment. At the same time, when the guide rails need to be polished, they no longer need to be sent to a factory with a proprietary polishing machine, saving polishing time and the cost required for sending and receiving the guide rails.

[0023] By setting the anti-slip device 3, when in use, the old guide rail 21 is inserted into the positioning plate 32 on the fixing plate 31 through the connecting groove 24, and the blocking of the old guide rail 21 by the positioning plate 32 reduces the influence of the axial stress generated during the processing on the supporting device 1, thereby preventing the fixing screw 12 and the limiting rod 14 from bending under long-term pushing. After installing the polishing guide rail 26, the limiting plate 35 is rotated to rotate around the rotating shaft 34 on the connecting block 33 until the limiting plate 35 and the polishing guide rail 26 are aligned. The end surface of the old guide rail 21 is fitted, and then the latch 36 is inserted. The latch 36 enters the connecting hole 25 of the old guide rail 21 through the limit plate 35. Since the vibration direction of the grinding guide rail 26 during the grinding process is perpendicular to the fitting surface of the limit plate 35, and the movement of the limit plate 35 is limited by the rotating shaft 34 in the opposite direction, and the limit plate 35 is difficult to be shaken open under the limitation of the latch 36, the limit plate 35 can be used as a barrier to block the axial direction of the grinding guide rail 26, thereby preventing the grinding guide rail 26 from slipping during the grinding process.

[0024] The grinding guide rail 26 is positioned and fixed by setting the anti-warping device 4 to cooperate with the supporting device 1, and the extrusion ring 13 is controlled to push the positioning device 2 close to the anti-warping device 4. The grinding guide rail 26 of the positioning device 2 is finally blocked by the limiting groove 46 of the extrusion strip 45, and the extrusion strip 45 is fixed by the supporting seat 41 and the base 11. In order to strengthen the connection strength of the supporting seat 41, a reinforcing rib 42 is also provided to strengthen the overall structural strength of the anti-warping device 4. After the positioning device 2 completes the initial fixation, it is still necessary to control the lower pressing plate 16 to position and fix the grinding guide rail 26. During the pressing process, the lower pressing plate 16 moves along the positioning rod 19 toward the base 11 until it is blocked by the fixing cylinder 151. During the process, the anti-warping block 17 under the lower pressure plate 16 gradually approaches the fixed block 43 on the support seat 41, and is gradually inserted into the insertion slot 44 on the fixed block 43. Since the connection controlling the movement of the lower pressure plate 16 is located in the middle of the lower pressure plate 16, in order to avoid warping at both ends of the lower pressure plate 16, anti-warping blocks 17 are arranged at both ends to interact with the fixed block 43 through the insertion slot 44. When the grinding guide rail 26 is performing the grinding operation, the grinding process is prone to vibration, causing the two ends of the lower pressure plate 16 to warp up, and the friction generated by the anti-warping block 17 and the fixed block 43 can offset the force generated by the vibration, thereby preventing the two ends of the lower pressure plate 16 from warping during long-term operation and preventing the lower pressure plate 16 from losing its fixing effect.
