Description

Technical Field

[0001] This utility model relates to the field of shift fork processing technology, and in particular to a shift fork punching device. Background Technology

[0002] The shift fork connects to the gear shift lever, and by shifting the intermediate gear wheel, the input / output speed ratio is changed, thus switching between different gears. For forward gears with synchronizers, the shift fork controls the engagement of the synchronizer gear ring; for reverse gears, the gear is directly engaged. The shift fork requires punching during manufacturing. Existing punching equipment requires manual fixing of the shift fork during machining, which is inefficient and poses a high risk.

[0003] Chinese Patent CN220144510U discloses a punching and perforating device for gearbox shift forks. The device includes a fixed frame, a clamping mechanism, and an expansion mechanism. The position of the support plate is adjusted by a third hydraulic telescopic rod to facilitate clamping and fixing shift forks of different sizes. At the same time, the mounting frame, pressure plate, and support plate provide three-point clamping for the shift fork, which can improve the stability of the shift fork clamping. The two support blocks are moved relative to each other by a bidirectional screw, so that the two support blocks expand and support the inner wall of the shift fork's jaw end, which facilitates clamping and fixing shift forks of different sizes. At the same time, the support blocks support the jaw end of the shift fork to prevent the shift fork from moving in the horizontal direction.

[0004] However, the device still has shortcomings: each clamping and fixing structure requires an independent drive mechanism, which makes the structure complex and parameter setting troublesome. In addition, the device needs to load and unload materials one by one and repeatedly complete feeding, opening and multi-directional clamping actions, resulting in long intervals and low processing efficiency.
