AI Technical Summary
In existing hardware processing clamps, the tapered part at the front end of the connecting column is prone to severe wear during repeated clamping, leading to increased production costs and increased labor costs for replacing the connecting column.
A fixed chuck including a damage prevention component and an adjustment component was designed. The damage prevention component uses a rubber wheel to contact and rotate against the inner wall of the chuck to press against the workpiece, reducing the wear of the limit post, and can be replaced in parts according to the damage condition. The adjustment component adjusts the position of the rubber wheel to adapt to different workpiece inner diameters through the cooperation of spring and limit post.
It effectively reduces wear on the limit post, lowers usage costs, and improves clamping flexibility and durability by replacing individual parts and adjusting the position of the rubber wheels.
