AI Technical Summary
In the current screw grinding process, manual operation cannot provide uniform radial thrust, which leads to deformation in the middle of the screw, affecting product quality and posing safety hazards.
Design a screw outer diameter grinding device, which uses a side pressure mechanism to press the screw surface on the opposite side of the grinding mechanism through the elastic force of a torsion spring, combined with a three-jaw chuck and center positioning to ensure the overall stability of the screw under force, and uses a slider and motor drive to achieve uniform grinding.
The radial support of the side pressure mechanism prevents the screw from bending laterally, ensuring the screw's machining quality and safety, and achieving a stable stress state.
