Description

Technical Field

[0001] The utility model relates to the technical field of shift fork production and processing equipment, in particular to a centering clamping mechanism. Background Art

[0002] At present, the shift fork is an important component of the automobile gearbox. It is located at the lower end of the shift handle and is connected to the shift handle. It is mainly used for clutch shifting. The function of the shift fork is to change the input and output speed ratio by shifting the intermediate speed wheel, thereby adjusting the speed and gear of the vehicle. The shift fork is a key component in the automobile gearbox and is responsible for adjusting the gear position to ensure the normal driving of the vehicle.

[0003] A shift fork clamp is disclosed in the Chinese utility model patent with the announcement number CN217992267U. Although the above-mentioned prior art limits the position of two shift forks with different fork distances, there is no need to replace the clamp or the clamping parts of the clamp. However, the shift fork is an important mechanical part inside a gearbox, and its processing accuracy directly affects the performance and service life of the entire machine. Therefore, during the processing, it is necessary to ensure that all parts of the shift fork can be accurately positioned without offset or shaking. The clamp clamps the shift fork from both sides. Such clamping will easily squeeze the forks of the shift fork, causing the processed shift fork to be deformed and unusable. The qualified rate of the shift forks processed in this way is low, and unqualified shift forks need to be recycled and processed, which will affect production efficiency and cause waste of resources. Therefore, it is necessary to design a centering clamping mechanism that will not cause any squeezing to the shift fork and is easy to produce. Utility Model Content

[0011] As a further improvement of the above solution, the two threaded posts (8) are arranged in a mirror image.

[0012] Through the above technical solution, when the threaded posts rotate, the two clamping blocks will move closer together, so that the fork can be centered and clamped and fixed.

[0016] Through the above technical solution, when the rack is pushed, the driving gear will drive the threaded post to rotate.

[0017] As a further improvement of the above solution, an oil cylinder is provided on one side of the limiting block, a push rod is fixedly installed at the pushing end of the oil cylinder, and one end of the push rod penetrates through the limiting block and extends to the inside of the protection groove and is fixedly installed with one end of the rack.

[0018] Through the above technical solution, the oil cylinder will move the rack.

[0019] As a further improvement of the above solution, an extension hole is provided on one side of the limit block, and the extension hole is adapted to the rack.

[0020] Through the above technical solution, the limit block will not block the movement of the rack.

[0029] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined with each other to form new embodiments.

[0030] Please refer to Figures 1 - 4The centering clamping mechanism of this embodiment includes a clamping plate 1, on which a plurality of shift forks 2 that need to be centered, positioned, and clamped are arranged. A clamping column is provided on one side of the shift forks 2. A clamping assembly that can center, position, and clamp adjacent shift forks 2 is provided on one side of each of the plurality of shift forks 2. A driving assembly that drives the clamping assembly to operate is provided on one side of each clamping assembly. The clamping assembly includes a mounting plate 301 fixedly mounted on the clamping plate 1 and having a sliding groove and two sliding plates 301 mounted on the sliding groove. The internal clamping block 302 has a "V"-shaped clamping groove on one side of each clamping block 302, which is used to clamp the clamping column of the fork 2. Limit plates 5 are fixedly installed on both sides of the mounting plate 301 to prevent the clamping block 302 from escaping the sliding groove. When the fork 2 is processed, the driving assembly will allow the clamping assembly to clamp the clamping column of the fork 2, so that the fork 2 is fixed in a horizontal state, so that the fork of the fork 2 will not be touched, thereby avoiding deformation of the fork 2.

[0031] Combine Figure 3 and Figure 4 A fixed block 6 with a rotating groove is fixedly installed inside the sliding groove, and a rotating block 7 is rotatably arranged inside the rotating groove. Threaded columns 8 are fixedly installed at both ends of the rotating block 7. One end of the two threaded columns 8 is threaded through the adjacent clamping blocks 302. The two threaded columns 8 are arranged in a mirror image. When the threaded columns 8 rotate, the two clamping blocks 302 are brought closer, so that the shift fork 2 can be clamped and fixed in the center.

[0032] Combine Figure 2 and Figure 3 , each mounting plate 301 is provided with a limit block 9 fixedly mounted on the fixture plate 1 on one side of the limit block 9, and a protective groove is provided inside the limit block 9. The driving assembly includes a connecting rod 401 fixedly mounted on one end of one of the threaded columns 8 and one end passes through the limit block 9 and extends to the inside of the protective groove, a driving gear 402 fixedly sleeved on one end of the connecting rod 401 located inside the protective groove, and a rack 403 provided on one side of the driving gear 402 and meshing with the driving gear 402. A cylinder 10 is provided on one side of the limit block 9, and a pushing rod 11 is fixedly mounted on the pushing end of the cylinder 10. One end of the pushing rod 11 passes through the limit block 9 and extends to the inside of the protective groove and is fixedly mounted on one end of the rack 403. An extension hole is provided on one side of the limit block 9, which is adapted to the rack 403. The cylinder 10 will allow the rack 403 to move, and when the rack 403 is pushed, the driving gear 402 will drive the threaded column 8 to rotate.

[0033] In the embodiment of the present application, the implementation principle of a centering and clamping mechanism is as follows: When the oil cylinder 10 pushes the push rod 11, the rack 403 will move. When the rack 403 moves, the driving gear 402 will rotate, thereby causing the connecting rod 401 to drive the threaded column 8 to rotate. When one threaded column 8 rotates, the rotating block 7 will drive the other threaded column 8 to rotate together. And since the two threaded columns 8 are arranged in a mirror image, when the two threaded columns 8 rotate, the two clamping blocks 302 will gradually close. The clamping grooves of the two clamping blocks 302 will perform centering positioning and clamping on the clamping column part of the fork 2. In this way, the fork 2 will be lifted and fixed. And since the bifurcated position of the fork 2 is not touched, the fork 2 will not be deformed during processing, which can effectively improve the processing quality of the fork 2. Such a setting can not only perform centering positioning and clamping on the fork 2 for convenient processing, but also avoid the clamp clamping and deforming the fork 2, resulting in low production quality of the fork 2.

[0034] The above-mentioned implementation manner is only the preferred implementation manner of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
