Description

General frock of arc quick clamping Technical Field The invention relates to a universal fixture for rapid clamping of an arc-shaped plate, and belongs to the technical field of machining and manufacturing. Background In the field of arc plate machining, the conditions of different arc lengths, heights and diameters of machined workpieces exist. At present, when arc-shaped plate products with different specifications are processed, arc-shaped tire molds with different specifications are often manufactured and matched with a pressing plate to clamp and fix an arc-shaped plate to be processed, or the arc-shaped plate to be processed is clamped and fixed by vacuum adsorption. However, when the arc-shaped plate to be processed is fixed based on the clamping means, clamping tools with different specifications are manufactured for the arc-shaped plates with different specifications, and the clamping tools matched with the arc-shaped plates are detached and replaced, so that the processing efficiency is greatly reduced. Therefore, how to realize the universality of the clamping tool is a problem to be solved at the present stage. Disclosure of Invention Aiming at the problems of the arc plate processing time clamping, the invention provides the arc plate rapid clamping universal tool which is simple in structure, convenient to assemble and disassemble and high in universality, can rapidly realize effective clamping of arc plates with different sizes, improves the arc plate processing efficiency, reduces the arc plate clamping tool cost and has good application prospect in the arc plate processing field.
