Description

Technical Field

[0001] The utility model belongs to the technical field of automobile shift fork processing, and more specifically relates to an auxiliary hole-opening device for an automobile shift fork. Background Art

[0002] In an automotive transmission, the shift fork must work closely with components such as the shift handle, intermediate shift wheel, and gear shaft to achieve smooth shifting. The height of the shift fork decreases gradually from a cylindrical structure, then a fan-shaped structure, and finally an arc-shaped structure, and the structures also vary. During the punching process of the shift fork, an auxiliary punching device is required to secure the shift fork. Existing auxiliary punching devices for shift forks mostly use electric or pneumatic push rods to clamp and secure the shift fork, thereby assisting the punching operation.

[0003] Existing application number CN202022850256.5 This utility model discloses a clamp for machining a gearbox shift fork, comprising a base plate, wherein the front and rear ends of the inner sides of the block are fixedly connected to the left and right sides of the slide rod, the left and right sides of the slide rod are slidably connected to clamping blocks, the inner sides of the clamping blocks are provided with second limiting grooves, the bottoms of the clamping blocks are slidably connected to spring blocks, the tops of the spring blocks are fixedly connected to first springs, the bottoms of the spring blocks are fixedly connected to latch teeth, the left and right sides of the top rear end of the base plate are fixedly connected to racks, the spring blocks are provided with sliding grooves, and the outer sides of the grooves are slidably connected to top blocks. In the utility model, the shift fork body is placed in the first limiting groove on the limiting block, and the clamping blocks are slid inwardly to engage with the left and right sides of the shift fork body to complete the fixation.

The clamping is stable and worthy of vigorous promotion.

The shift forks after thermal deformation are not convenient to fit well into the existing auxiliary hole-opening device, and there is a slight error, so it is not convenient to tightly fix the shift forks after thermal deformation.
