Explosion-proof zipper polishing device

By designing an explosion-proof zipper polishing device, the precise gap adjustment of the two polishing modules is achieved by using an adjusting screw and guide column. This solves the problem of the need for manual rotation of traditional polishing devices, and realizes efficient and uniform polishing of the upper and lower surfaces of the explosion-proof zipper, improving the product's sealing performance and safety.

AI Technical Summary

Technical Problem

Traditional grinding devices grind explosion-proof zippers on only one side, requiring manual flipping, which makes it difficult to maintain consistency and precision, affecting the product's sealing and safety.

Method used

An explosion-proof zipper polishing device was designed, comprising a frame, a polishing module, and a lifting module. The precise gap between the two polishing modules is adjusted by adjusting the lead screw and guide column, enabling simultaneous polishing of both the upper and lower surfaces of the explosion-proof zipper. The support mechanism and limit rod ensure stability and accuracy.

Benefits of technology

It achieves efficient and uniform grinding of explosion-proof zippers, improving grinding efficiency and product consistency, and ensuring sealing and safety.

Abstract

This utility model relates to the field of machining equipment technology, and specifically to an explosion-proof zipper grinding device. It includes a frame, grinding modules, and a lifting module. The frame comprises an upper frame and a lower frame, on which two grinding modules are mounted. The lifting module includes a guide column and an adjustment mechanism. The lower fixed seat of the adjustment mechanism is fixed to the lower frame, and an adjusting screw is rotatably mounted on the lower fixed seat and threadedly connected to the upper fixed seat of the upper frame. This utility model controls the lifting of the upper frame by rotating the adjusting screw, with stable guidance from the guide column, allowing for rapid adjustment of the gap between the two grinding modules to accommodate explosion-proof zippers of different thicknesses. The two grinding modules achieve simultaneous grinding on both sides, significantly improving efficiency.
