Pressure-maintaining vacuum suction cup jig for processing sheet parts in horizontal machining center

Abstract

The invention provides a pressure-maintaining vacuum suction cup jig for processing sheet parts in a horizontal machining center. The pressure-maintaining vacuum suction cup jig comprises a vacuum adsorption platform, a sealing ring, a cover plate, a straight-through small ball valve, a pressure gauge, a bushing, a positioning pin, and a base; the vacuum adsorption platform is connected with the cover plate through a bolt and the sealing ring; the straight-through small ball valve is installed on one sidewall of the vacuum adsorption platform; the pressure gauge is installed on the other sidewall of the vacuum adsorption platform; the vacuum adsorption platform is installed on the base through the positioning pin and the bushing; and then the vacuum adsorption platform is fixedly connectedwith the base by adopting screws. The pressure-maintaining vacuum suction cup jig provided by the invention greatly reduces the clamping time and the clamping number, realizes uninterrupted operationof the machine tool, and improves the production efficiency and product quality by virtue of continuous machining of the parts.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing thin plate fixtures. Most of the current thin plate parts are mechanically pressed by pressure plates and screws during milling. Due to the limitation of the characteristics of the parts, it is necessary to make special pressure plates and limit them when processing certain features. Position, cumbersome clamping, is not conducive to mass production, greatly reduces production efficiency, resulting in increased costs. This jig is beneficial to atmospheric pressure instead of mechanical compression, which can solve the above problems, fast clamping, stable structure, and greatly improve production efficiency. Background technique [0002] The processing of thin-plate parts has always been a difficult point in mechanical processing. Since the incoming material is of equal-thickness plate structure, the high precision of features needs to be processed in one order, and high repeat posit...

AI Technical Summary

Problems solved by technology

If the mechanical compression structure of the pressure plate and the screw is used, the operation is cumbersome, the production efficiency is reduced, and the product quality is affected

Suction cup structure jigs exist in the market, but the disadvantage is that the instability of the air pressure source may cause abnormal parts.
