[0025] The following will combine the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.
[0026] Example:
[0027] See also Figure 1-Figure 5 , the utility model provides a technical solution:
[0028] A vehicle transmission shift fork grinding device includes a workbench body 1, a placement platform 2 is provided on the top of the workbench body 1, a fixed block 3 is provided on the top of the placement platform 2, a limit assembly 4 is provided inside the fixed block 3, a connecting frame 5 is provided on the top of the workbench body 1 and outside the placement platform 2, a first guide rail 6 is provided on the outside of the connecting frame 5, a second guide rail 7 is provided on the outside of the first guide rail 6, a third guide rail 8 is provided on the outside of the second guide rail 7, a connecting seat 9 is provided on the outside of the third guide rail 8, a grinding block 10 is provided on the outside of the connecting seat 9, and a dust collection assembly 11 is provided on the outside of the connecting frame 5 and outside the first guide rail 6;
[0029] The limiting assembly 4 is used to limit the shift fork placed outside the fixed block 3, and the limiting assembly 4 consists of a fixed frame 12, a movable block 13, a limiting block 14 and an elastic strip 15. The fixed frame 12 is located inside the fixed block 3, and the two sets of movable blocks 13 are slidably connected to the outside of the fixed frame 12. The limiting block 14 is located at the end of the movable block 13 away from the fixed frame 12, and the elastic strip 15 is located at the end of the limiting block 14 away from the movable block 13;
[0030] The dust collecting assembly 11 is used to absorb the dust generated by the grinding block 10 during grinding.
[0031] Furthermore, a fixing groove 16 is provided on the outer side of the fixing block 3, and a sliding groove is provided inside the fixing groove 16. The internal structure size of the sliding groove is designed to correspond to the external structure size of the limit block 14. When the speed fork is polished, the speed fork is placed inside the fixing groove 16 so that the speed fork can contact with the limit component 4. The speed fork can be limited by the limit component 4 to prevent the speed fork from loosening, which affects the polishing effect. When the speed fork contacts the fixing groove 16, the limit block 14 can contact with the speed fork through the sliding groove.
[0032] Among them, a driving rack 17 is provided at one end of the moving block 13 away from the limit block 14, and a guide gear 18 is rotatably connected to the outside of the fixed frame 12 and located between the two sets of driving racks 17. The guide gear 18 and the driving rack 17 are meshed and connected. When the driving rack 17 is connected to the guide gear 18, when one set of driving racks 17 is displaced, the guide gear 18 is driven to rotate, so that the other set of driving racks 17 is displaced, thereby causing the two sets of moving blocks 13 to be displaced, driving the limit block 14 to be displaced.
[0033] Secondly, a first telescopic cylinder is provided at the end of the fixed frame 12 away from the moving block 13, and a connecting rod 19 is provided at the driving end of the first telescopic cylinder. The end of the connecting rod 19 away from the first telescopic cylinder is connected to the moving block 13. When the connecting rod 19 is connected to the moving block 13 and the first telescopic cylinder is started, the connecting rod 19 is driven to move, so that the moving block 13 is moved. When the moving block 13 is moved, the driving rack 17 can be driven to move.
[0034] Furthermore, two sets of sliding rods are provided at one end of the fixed frame 12 close to the moving block 13. The moving block 13 is slidably connected to the sliding rods, and the moving block 13 is connected to the fixed frame 12 through the sliding rods. By connecting the moving block 13 to the sliding rods, the moving block 13 can be connected to the fixed frame 12. When the moving block 13 is displaced, it can be guided by the sliding rods to prevent it from being offset.
[0035] Furthermore, the dust suction assembly 11 consists of a dust suction pipe 20, a guide pipe 21, a dust suction pump 22 and a collection box 23. The dust suction pipe 20 is located on the outside of the connecting frame 5 and close to one end of the fixed block 3. The guide pipe 21 is located on the outside of the dust suction pipe 20 and on the outside of the connecting frame 5. The dust suction pump 22 is located on the outside of the connecting frame 5 and is connected to the guide pipe 21. The collection box 23 is located on the outside of the connecting frame 5 and is connected to the dust suction pump 22. When the speed fork is polished, the dust suction pump 22 is started, and the dust generated by polishing is introduced into the interior of the dust suction pipe 20 through the guide pipe 21, so that the dust is introduced into the interior of the guide pipe 21, and then introduced into the interior of the collection box 23 through the dust suction pump 22, so as to prevent the dust from floating in the air and affecting the working environment, thereby endangering the health of the operator.
[0036] Furthermore, a spiral groove 24 is provided inside the guide tube 21, and the guide tube 21 is connected to a guide block 27 through the spiral groove 24. A compression spring 25 is provided on the outside of the guide block 27, and a cleaning block 26 is provided on one end of the guide block 27 close to the compression spring 25. A second telescopic cylinder is provided on the outside of the guide tube 21, and the driving end of the second telescopic cylinder extends to the inside of the guide tube 21 and is connected to the guide block 27. When the dust suction tube 20 adsorbs debris, the debris adheres to the inner wall of the dust suction tube 20 after a long period of operation. When the debris accumulates too much, it will affect the adsorption effect of the dust suction tube 20. At this time, the dust suction tube 20 is started. The second telescopic cylinder drives the guide block 27 to move, and the spiral groove 24 enables the guide block 27 to rotate and move, driving the cleaning block 26 to move, and moving the cleaning block 26 to the inside of the dust suction pipe 20, so that the inner wall of the dust suction pipe 20 can be cleaned. The rotation of the cleaning block 26 makes it possible to better clean the debris attached to the inner wall of the dust suction pipe 20, preventing the debris from affecting the operation of the dust suction pipe 20. When the guide block 27 drives the cleaning block 26 to move, the compression spring 25 can prevent the guide block 27 from instantly transmitting too much force to the cleaning block 26, causing damage to the cleaning block 26.
[0037] In this embodiment, the implementation scenario is specifically as follows: when the speed change fork is polished, the speed change fork is placed inside the fixed groove 16, and the first telescopic cylinder is started to drive the connecting rod 19 to move so that the moving block 13 is displaced. When the moving block 13 is displaced, it can drive the driving rack 17 to move. When one set of driving racks 17 is displaced, it drives the guide gear 18 to rotate, so that the other set of driving racks 17 is displaced, thereby causing the two sets of moving blocks 13 to move, driving the limit block 14 to move. The limit block 14 can contact the speed change fork through the sliding groove to limit the speed change fork and prevent the speed change fork from loosening. Through the design of the first guide rail 6, the second guide rail 7, the third guide rail 8 and the polishing block 10, the polishing block 10 is moved to the top of the speed change fork so that the speed change fork can be polished. When the speed change fork is polished, the dust suction pump 22 is started to guide the dust generated by polishing into the suction pipe through the guide pipe 21. The interior of the dust pipe 20 allows the dust to be introduced into the interior of the guide pipe 21 and then into the interior of the collection box 23 through the dust suction pump 22, preventing the dust from floating in the air and affecting the working environment, thereby endangering the health of the operator. When the dust suction pipe 20 absorbs debris, it operates for a long time and the debris adheres to the inner wall of the dust suction pipe 20. When too much accumulation occurs, it affects the adsorption effect of the dust suction pipe 20. At this time, the second telescopic cylinder is started to drive the guide block 27 to move. The spiral groove 24 allows the guide block 27 to rotate and move, driving the cleaning block 26 to move, and moving the cleaning block 26 to the interior of the dust suction pipe 20 so that the inner wall of the dust suction pipe 20 can be cleaned. The rotation of the cleaning block 26 makes it possible to better clean the debris attached to the inner wall of the dust suction pipe 20, preventing the debris from affecting the operation of the dust suction pipe 20. Compared with the existing grinding equipment, the utility model can improve the overall practicality of the grinding equipment through design.
