Hydraulic-linked expansion clamp

Abstract

The invention discloses a hydraulic-linked expansion clamp and belongs to the technical field of design of machine tool clamps. The hydraulic-linked expansion clamp comprises a clamp body, an oblique sliding block seat, a coupling screw, a left clamping oblique block, a right clamping oblique block, a clamp cover, a belleville spring, a pull rod, a pull rod thread, a connecting disc, a screw, a positioning pin and a workpiece. The clamp body is fixed to the connecting disc through the screw and positioned through the positioning pin. A through hole is machined in the middle of a cylindrical part on the right side of the clamp body. The oblique sliding block seat is placed on the right side of the interior of the through hole. The oblique sliding block seat is fixed to the pull rod through the coupling screw. The left side of the oblique sliding block seat abuts against the shaft shoulder of the pull rod through the belleville spring. One end of the left clamping oblique block and one end of the right clamping oblique block are attached to the oblique sliding block seat, and the other end of the left clamping oblique block and the other end of the right clamping oblique block abut against the inner surface of the workpiece. The right side face of the whole clamp body is positioned by the clamp cover. The hydraulic-linked expansion clamp is capable of clamping various irregular workpieces, end face machining is convenient, the workpieces can be clamped and released conveniently, and the clamping force is reliable.

Description

technical field [0001] The invention relates to the technical field of machine tool fixture design, in particular to a hydraulic linkage expansion clamp. Background technique [0002] With the development of the machinery industry, the requirements for the shape of the parts vary widely. Different clamping methods must be used for workpieces of different shapes when they are processed on the machine tool. It can also be solved, but it is difficult to clamp when encountering parts with complex shapes. Usually, the tip auxiliary clamping is required at the end of the part. It is necessary to clamp a variety of irregular workpieces, with convenient end surface processing, convenient clamping and loosening of the workpiece, and reliable clamping force for clamping the inner hole of the workpiece. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art that traditional fixtures are difficult to clamp parts with comple...
