Clamping equipment special for machining double holes in gasket

Abstract

The invention relates to clamping equipment special for machining double holes in a gasket. The clamping equipment comprises a pedestal, fixed positioning blocks, slide compressing blocks and compressing cylinders. The pedestal is composed of a main plate and supporting plates. A row of the compressing cylinders which are vertically arranged upwards are evenly installed on the lower bottom face of the main plate. A piston rod of each compressing cylinder is connected with a wedge-shaped block. The slide compressing blocks abut against the front side wall and the rear side wall of each wedge-shaped block, and the contact surfaces of the slide compressing blocks and the wedge-shaped blocks are inclined planes. Each slide compressing block is arranged on the upper surface of the main plate. The outer side of each slide compressing block is provided with one corresponding fixed positioning block. The inner wall surfaces of the slide compressing blocks and the inner wall surfaces of the fixed positioning blocks are both provided with grooves used for positioning workpieces. Two through holes are formed in the main plate and located between the slide compressing blocks and the fixed positioning blocks. The clamping equipment special for machining the double holes in the gasket is ingenious in design, reasonable in structure, and easy and convenient to operate. By the adoption of the clamping equipment, working efficiency can be improved, product quality is improved, the amount of labor is decreased and enterprise cost is reduced.

Description

technical field [0001] The invention relates to a clamping fixture in the technical field of machining, in particular to a special clamping device for double-hole gaskets. Background technique [0002] At present, the clamps used for drilling double holes on the circular gasket are relatively simple, and can only clamp one workpiece at a time, so there are problems of slow processing speed and low efficiency. In addition, the existing clamps are usually three-jaw clamps, which rely on clamping the outer edge of the circular gasket for positioning. Since it needs to be manually clamped by the staff, the clamping force is not easy to control, so it is easy to move the outer edge of the gasket. There are traces on the surface, and even deformation, so that the workpiece becomes a waste product and cannot be used. Contents of the invention [0003] The purpose of the present invention is to make up for the deficiencies of the prior art, and to provide a special clamping devic...
