Description

Technical Field

[0001] This utility model relates to the field of shift fork processing technology, specifically a shift fork gripping surface polishing device. Background Technology

[0002] As a key actuator in automotive transmission systems, the shift fork is primarily used to actuate synchronizers or sliding gears, enabling the engagement and disengagement of gears in different gear positions, directly impacting shift smoothness and transmission reliability. The gripping surface at the end of the shift fork requires high precision and low roughness, as it withstands continuous friction and impact loads during frequent gear shifts. Burrs, scale, or machining marks on the gripping surface can easily lead to abnormal wear, increased noise, or even shifting jamming, shortening the transmission's lifespan. Therefore, in the manufacturing process, the shift fork gripping surface must be polished to eliminate surface defects, improve wear resistance and fatigue strength, ensure stable contact with mating parts, and guarantee the transmission system's operational accuracy and reliability. Currently, this process largely relies on subsequent precision machining and is a crucial step in improving shift fork performance.

[0003] Existing fork polishing devices mostly employ a fixed clamping structure, requiring manual positioning and clamping of the fork to be polished onto the tooling fixture before polishing. After polishing, the fixture must be released and the workpiece manually removed before the next part can be clamped and processed. This single-piece operation mode has significant efficiency bottlenecks: on the one hand, the repeated clamping and disassembly process is time-consuming, reducing overall processing efficiency; on the other hand, manual operation makes it difficult to ensure consistent clamping positions, easily introducing positioning errors and affecting polishing uniformity. In addition, during continuous production, operators need to intervene frequently, resulting in high labor intensity and a high risk of safety accidents or quality fluctuations due to fatigue.

[0004] Based on this, a fork-grip polishing device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0027] In one embodiment, such as Figures 1-6 As shown, a fork-grip polishing device includes a switching disk 13 and a polishing component 27. A fixed shaft is fixedly mounted at the bottom of the switching disk 13, and the fixed shaft is rotatably mounted in a rotating hole at the upper end of a mounting platform 15. One end of the fixed shaft is fixedly connected to the output end of a motor 14, which is fixedly mounted at the bottom of the mounting platform 15. A plurality of positioning seats 11 are arrayed on the upper end of the switching disk 13. Each positioning seat 11 has a bearing groove at its upper end, and a positioning tube 16 is fixedly mounted within the bearing groove. A sliding block 12 is fixedly mounted at the bottom end of each positioning seat 11. All moving blocks 12 are slidably disposed in the guide groove at the upper end of the switching disk 13. Each of the bearing grooves is provided with a clamping mechanism for positioning and clamping the shift fork body 34. A mounting cover is fixedly disposed on the outside of the grinding component 27. A first guide slide rod is symmetrically slidably disposed on the mounting cover. The first guide slide rod is fixedly disposed at the bottom end of the top plate 31. An adjustment mechanism is provided at the bottom end of the top plate 31 for adjusting the grinding position of the gripping surface of the shift fork body 34. The clamping mechanism facilitates positioning and clamping of the shift fork body 34, and the adjustment mechanism facilitates adjustment of the working position of the grinding component 27.

[0028] The clamping mechanism includes clamping plates 20. Each clamping plate 20 is symmetrically arranged within the bearing groove. Both clamping plates 20 are slidably mounted on second guide rods. The second guide rods are fixedly mounted inside the positioning seat 11. Each clamping plate 20 has a second connecting rod 21 hinged to its end. The other end of the second connecting rod 21 is hinged to both ends of a hinge rod 22. Each hinge rod 22 has a fixed top rod 23 at its bottom end. A fixed plate is fixedly mounted on the top rod 23.

A mounting groove is provided on one side of the guide groove corresponding to the position of the tension spring 32. The other end of the tension spring 32 is fixedly connected to the end of the mounting groove.

[0029] A guide plate 25 is provided above the mounting platform 15. A third guide slide rod is symmetrically provided at the bottom end of the guide plate 25. The third guide slide rod is slidably disposed within a sliding hole at the upper end of the mounting platform 15. The bottom end of the guide plate 25 is fixedly connected to the output end of a first electric cylinder 26, which is fixedly disposed within a mounting hole at the upper end of the mounting platform 15. Both ends of the guide plate 25 are inclined. In use, when polishing the gripping surface of the shift fork body 34 is required, the shift fork body 34 to be polished is placed in a bearing groove at the upper end of a positioning seat 11. Simultaneously, the end of the shift fork body 34 is inserted through a hole into the positioning tube 16, allowing the shift fork body to be polished. 34 performs initial positioning. Then, the output of motor 14 drives the switching disk 13 to rotate intermittently at a fixed angle. When the end of the push rod 23 engages with the end of the guide plate 25, the guide plate 25 guides the push rod 23, causing the push rod 23 to slide along the hinge rod 22. The hinge rod 22, through the second connecting rod 21, drives the clamping plate 20 to slide, thereby positioning and clamping the shift fork body 34. At the same time, when it is necessary to adjust the distance between the ends of the two clamping plates 20, the output of the first electric cylinder 26 drives the guide plate 25 to move, thereby adjusting the initial height of the guide plate 25, thus allowing the distance between the two clamping plates 20 to be adjusted.

[0030] The positioning tube 16 is equipped with a hinged plate that slides inside. The hinged plate has a threaded hole in the middle, and a threaded rod 19 is fitted inside the threaded hole.

The limiting slide rod is slidably mounted in the limiting slide hole at the bottom end of the positioning tube 16. In use, when it is necessary to accurately position the end hole of the shift fork body 34, the threaded rod 19 is rotated according to the end hole diameter of the shift fork body 34. Under the action of the thread, the hinged plate slides inside the positioning tube 16. The positioning tube 16 drives the adjusting plate 17 to move through the first connecting rod 18, thereby enabling accurate positioning of the shift fork body 34.

[0031] The adjustment mechanism includes a second electric cylinder 28 and a push rod 29. The mounting cover is fixedly connected to the output end of the second electric cylinder 28. The second electric cylinder 28 is fixedly mounted on the bottom end of the top plate 31. The push rod 29 is located at the bottom end of the top plate 31 and one side of the positioning seat 11. The push rod 29 is fixedly mounted on the output end of the third electric cylinder 30. The third electric cylinder 30 is fixedly mounted on the bottom end of the top plate 31. In use, when the shift fork body 34 rotates with the positioning seat 11 to below the polishing component 27 and stops, the polishing component 27, the second electric cylinder 28, and the push rod 29 are activated. The output end of the third electric cylinder 30 drives the push rod 29 to move, and the push rod 29 pushes the positioning seat 11 to move. At the same time, the second electric cylinder 28 drives the polishing component 27 to move along the axial direction of the first guide slide rod, thereby polishing the gripping surface of the shift fork body 34.

[0032] A collection cover 33 is provided at the upper end of the mounting platform 15, corresponding to the position below the grinding component 27, so that impurities can be collected during use.

[0033] The bottom of the switching disk 13 is provided with a number of support rods 36, and each support rod 36 is provided with a ball bearing at its end. The ball bearing is in close contact with the upper end of the mounting platform 15, which facilitates auxiliary support for the switching disk 13 during use.

[0034] The upper end of the mounting platform 15 is equipped with a control component 35. The control component 35 is electrically connected to the motor 14, the first electric cylinder 26, the grinding component 27, the second electric cylinder 28, and the third electric cylinder 30. In use, it is convenient for the user to control the motor 14, the first electric cylinder 26, the grinding component 27, the second electric cylinder 28, and the third electric cylinder 30 through the control component 35.

[0035] The above embodiment discloses a fork gripping surface polishing device. When polishing the gripping surface of the fork body 34, the fork body 34 to be polished is placed in the upper bearing groove of a positioning seat 11. Simultaneously, the end of the fork body 34 is inserted through a hole into the positioning tube 16, thus initially positioning the fork body 34. Then, the output of the motor 14 drives the switching disk 13 to rotate intermittently at a fixed angle. When the end of the push rod 23 engages with the end of the guide plate 25, the guide plate 25 guides the push rod 23, causing the push rod 23 to hinge. When the lever 22 slides, the hinge lever 22 drives the clamping plate 20 to slide through the second connecting rod 21, thereby positioning and clamping the shift fork body 34. When the shift fork body 34 rotates with the positioning seat 11 to below the grinding component 27 and stops, the grinding component 27, the second electric cylinder 28 and the push rod 29 are activated. The output end of the third electric cylinder 30 drives the push rod 29 to move. The push rod 29 pushes the positioning seat 11 to move. At the same time, the second electric cylinder 28 drives the grinding component 27 to move along the axial direction of the first guide slide rod, thereby polishing the gripping surface of the shift fork body 34.

[0036] When it is necessary to adjust the distance between the ends of the two clamping plates 20, the output end of the first electric cylinder 26 drives the guide plate 25 to move, thereby adjusting the initial height of the guide plate 25, so that the distance between the two clamping plates 20 can be adjusted. When it is necessary to accurately position the through hole at the end of the shift fork body 34, the threaded rod 19 is rotated according to the hole diameter at the end of the shift fork body 34. Under the action of the thread, the hinge plate slides inside the positioning tube 16. The positioning tube 16 drives the adjusting plate 17 to move through the first connecting rod 18, thereby accurately positioning the shift fork body 34.

[0037] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
