Description

Technical Field

[0001] This utility model relates to the field of grinding fixture technology, specifically a high-precision automotive shift fork grinding fixture. Background Technology

[0002] The shift fork is a crucial component in a transmission used for gear shifting. Connected to the gear lever, it moves when the driver operates the lever, changing the position of the gears and enabling gear switching. By shifting the intermediate gear wheel or other related gears, the shift fork alters the speed ratio between the input and output shafts to adapt to different driving conditions. During gear shifting, the shift fork acts on the synchronizer ring gear to engage and disengage the forward gears. As a core transmission component of the transmission, the surface precision and geometric stability of the shift fork are critical to shifting performance. Therefore, high-precision fixtures are typically required to clamp and secure the shift fork during surface grinding.

[0003] In the precision grinding process of existing automotive shift forks, clamps are usually required to hold and fix the shift forks. However, in actual grinding, since the shift forks are irregularly shaped parts, common flat clamps and V-shaped clamps cannot hold and fix the shift forks well. The clamping force is relatively insufficient, and the shift forks are prone to tilting and falling off during grinding. It is also impossible to hold and fix the shift forks stably from multiple points. The clamping capacity of the clamps is relatively insufficient, and the practicality and adaptability are not good enough. To solve the above problems, we propose a high-precision automotive shift fork grinding clamp. Utility Model Content
