[0026] Example two: please refer to Figure 1 - Figure 7The application provides a technical scheme: on the basis of the embodiment one, the anti-slip device 3 comprises a fixed plate 31, the two sides of the fixed plate 31 are fixedly connected with positioning plates 32, the outer wall of the positioning plates 32 is fixedly connected with connecting blocks 33, the inner wall of the connecting blocks 33 is rotatably connected with rotating shafts 34, the outer wall of the rotating shafts 34 is rotatably connected with limiting plates 35, the inner wall of the limiting plates 35 is slidably connected with bolts 36, the outer wall of the positioning plates 32 is slidably connected with the outer wall of the old guide rail 21 through the connecting grooves 24, the outer wall of the bolt 36 is slidably connected with the inner wall of the positioning plate 32, the old guide rail 21 is inserted into the positioning plates 32 on the fixed plate 31 through the connecting grooves 24, the influence of the axial stress generated in the machining process on the supporting device 1 is reduced through the blocking of the old guide rail 21 by the positioning plates 32, and then the fixed screw rod 12 and the limiting rod 14 are prevented from being bent under long-time pushing, after the installation of the polishing guide rail 26, the limiting plate 35 is rotated around the rotating shaft 34 on the connecting block 33 until the limiting plate 35 is attached to the end face of the polishing guide rail 26, then the bolt 36 is inserted, and the bolt 36 enters the connecting hole 25 of the old guide rail 21 through the limiting plate 35, because the vibration direction generated in the polishing process of the polishing guide rail 26 is perpendicular to the attached surface of the limiting plate 35, the movement direction of the limiting plate 35 is limited by the rotating shaft 34, and the limiting plate 35 is difficult to be shaken off under the limiting of the bolt 36.
[0027] The anti-warping device 4 comprises a supporting seat 41, the outer wall of the supporting seat 41 is fixedly connected with reinforcing ribs 42, the outer wall of the supporting seat 41 is fixedly connected with fixed blocks 43, the wall of the fixed blocks 43 is provided with an insertion groove 44, the outer wall of the supporting seat 41 is fixedly connected with extrusion strips 45, the wall of the extrusion strips 45 is provided with limiting grooves 46, the bottom of the supporting seat 41 is fixedly connected with the top of the base 11, the outer wall of the fixed block 43 is slidably connected with the outer wall of the anti-warping block 17 through the insertion groove 44, the outer wall of the extrusion strip 45 is slidably connected with the outer wall of the polishing guide rail 26 through the limiting groove 46, the polishing guide rail 26 is positioned and fixed by the control lower pressing plate 16, in the pressing process, the lower pressing plate 16 moves towards the base 11 along the positioning rod 19 until being blocked by the fixed cylinder 151, in this process, the anti-warping block 17 below the lower pressing plate 16 gradually approaches the fixed block 43 on the supporting seat 41 and gradually inserts into the insertion groove 44 on the fixed block 43, because the connecting part for controlling the movement of the lower pressing plate 16 is located at the middle position of the lower pressing plate 16, in order to avoid the warping of the two ends of the lower pressing plate 16, the anti-warping block 17 and the fixed block 43 are arranged at the two ends and interact with each other through the insertion groove 44, when the polishing guide rail 26 is polished, the polishing process is easy to vibrate, which causes the two ends of the lower pressing plate 16 to be warped, and the friction generated by the anti-warping block 17 and the fixed block 43 can offset the force generated by the vibration, and then the warping of the two ends of the lower pressing plate 16 under long-time work is prevented.
[0028] Working principle:
[0029] In use, the support device 1 and the positioning device 2 are arranged so that the self-made tool has a certain polishing precision, and the old guide rail 21 that is no longer used is removed for use. Since the angle of the guide rail of the old guide rail 21 is ninety degrees, and the angle of the corner position of the polishing guide rail 26 is also ninety degrees, the corner position of the polishing guide rail 26 is placed in the guide rail position of the old guide rail 21, thereby ensuring that the guide rail side wall of the polishing guide rail 26 remains relatively parallel to the bottom of the tool. The old guide rail 21 is holed, and the old guide rail 21 is inserted into the limiting rod 14 and the fixed screw 12 by opening the sliding hole 22 and the limiting hole 23. Then, the pressing ring 13 is rotated to drive the pressing ring 13 to press the positioning device 2, so that the positioning device 2 is pressed by the pressing ring 13 and the anti-warping device 4. At this time, the horizontal radial movement of the positioning device 2 is limited. The lower pressing plate 16 is lifted, and then the limiting ring 153 is controlled by the adjusting device 15 to press downward, and the lower pressing plate 16 is fixed. During the process of fixing the lower pressing plate 16, the threaded connecting rod 152 is fixed in position, and the lower pressing plate 16 is limited between the fixed cylinder 151 and the anti-escape bolt 154. By rotating the limiting ring 153, the pressing groove 18 of the lower pressing plate 16 can press the positioning device 2, thereby completing the vertical radial movement of the positioning device 2, and the anti-slip device 3 completes the axial movement of the positioning device 2. At this time, the positioning device 2 is fixed as a whole. When the operator polishes the polishing guide rail 26, the polisher can ensure the guide rail precision after the polishing of the polishing guide rail 26.
[0030] The self-made tool has a simple structure and certain precision. Since the structure is simple and the material is easy to obtain, the manufacturing and maintenance cost of the tool is low. Since no complex process and expensive materials are required, the production investment is also reduced. The simple structure also makes it more convenient for workers to operate the tool, so that the operator can quickly get started, thereby reducing the training time and cost. On the basis of simple structure, the precision of the guide rail itself ensures that the surface to be polished of the polishing guide rail 26 remains horizontal when the tool positions and polishes the polishing guide rail 26, so that the worker can accurately process the worn parts of the guide rail, thereby improving the flatness and straightness of the guide rail, so that the polished guide rail can be used by the equipment. In the repair of machine tool guide rails, machining errors can be effectively reduced, product quality can be improved, and the service life of guide rails and related equipment can be prolonged. At the same time, when the guide rail needs to be polished, it does not have to be sent to a factory with a special polishing machine, saving polishing time and the cost of sending and receiving guide rails.
[0031] By setting the anti-slip device 3, because in use, the old guide rail 21 is inserted into the positioning plate 32 on the fixed plate 31 through the connecting groove 24, the blocking of the old guide rail 21 by the positioning plate 32 reduces the influence of the axial stress generated during processing on the support device 1, thereby preventing the fixed screw 12 and the limiting rod 14 from bending under long-term pushing, after installing the polishing guide rail 26, rotating the limiting plate 35 to make it rotate around the rotating shaft 34 on the connecting block 33 until the limiting plate 35 is attached to the end face of the polishing guide rail 26, then insert the pin 36, the pin 36 enters the connecting hole 25 of the old guide rail 21 through the limiting plate 35, because the vibration direction of the polishing guide rail 26 during polishing is perpendicular to the attached surface of the limiting plate 35, and the movement of the limiting plate 35 is limited in the opposite direction by the rotating shaft 34, and the limiting plate 35 is difficult to be shaken off under the limiting of the pin 36, so the limiting plate 35 can act as a barrier to block the axial direction of the polishing guide rail 26, thereby preventing the polishing guide rail 26 from slipping during polishing.
[0032] By setting the anti-warping device 4 in cooperation with the support device 1 to position and fix the polishing guide rail 26, control the positioning device 2 to push the anti-warping device 4 close to the support seat 41, and the polishing 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 support seat 41 and the base 11, and the reinforcing ribs 42 are additionally provided to strengthen the connection strength of the support seat 41 and the overall structural strength of the anti-warping device 4, after the preliminary fixation of the positioning device 2, the polishing guide rail 26 still needs to be positioned and fixed by the control of the lower pressing plate 16, during the pressing process, the lower pressing plate 16 moves along the positioning rod 19 towards the base 11 until it is blocked by the fixed cylinder 151, in this process, the anti-warping blocks 17 below the lower pressing plate 16 gradually approach the fixed blocks 43 on the support seat 41 and gradually insert into the insertion grooves 44 on the fixed blocks 43, because the connection for controlling the movement of the lower pressing plate 16 is located at the middle position of the lower pressing plate 16, in order to avoid the warping of the two ends of the lower pressing plate 16, therefore, the anti-warping blocks 17 and the fixed blocks 43 interact through the insertion grooves 44, when the polishing guide rail 26 is polished, the polishing process is easy to shake, which causes the two ends of the lower pressing plate 16 to warp, and the friction generated by the anti-warping blocks 17 and the fixed blocks 43 can offset the force generated by the shaking, thereby preventing the two ends of the lower pressing plate 16 from warping for a long time and preventing the lower pressing plate 16 from losing its fixing effect.
[0033] Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art and related fields without creative labor should belong to the scope of protection of the present application.
