Description

Technical Field

When fixing the gear block, the staff rotates the first screw so that the first screw pushes the clamping member to move toward the gear blank, thereby causing the clamping block to be stuck in the tooth mouth of the gear blank. The gear blank is limited by the clamping block cooperating with the tooth mouth of the gear blank, thereby improving the stability of the gear blank, and the cylinder pushes the mounting plate downward, and the telescopic rod drives the interference block to move downward and contact the top of the gear blank. When the cylinder continues to apply pressure, the spring and the telescopic rod contract, thereby causing the interference block to press the top of the gear blank, further improving the stability of the gear blank during punching, preventing the gear blank from offsetting during punching, reducing the scrap rate during punching, and having strong practicality.
