Bidirectional clamping fixture

Abstract

The invention relates to a clamping fixture, in particular to a bidirectional clamping fixture. The bidirectional clamping fixture comprises a fixture body, an outer wall clamping jaw, an inner wall clamping jaw, a bolt, a nut and a washer, wherein the outer wall clamping jaw and the inner wall clamping jaw are used for clamping a workpiece; the bolt serves as a force application device; the driving end of the outer wall clamping jaw and the middle part of the inner wall clamping jaw are respectively hinged on the fixture body; driven ends of the outer wall clamping jaw and the inner wall clamping jaw are respectively used for clamping the workpiece; the middle part of the outer wall clamping jaw is provided with a threaded hole; the bolt passes through the threaded hole; one end of the bolt is connected with the nut and the washer; and the other end of the bolt is hinged with the driving end of the inner wall clamping jaw. The bidirectional clamping fixture disclosed by the technical scheme adopted by the invention is strong in adjustability on pressure strength of the workpiece, accurate in positioning, simple in structure and easy in operation.

Description

technical field [0001] The invention relates to a clamping fixture, in particular to a bidirectional clamping fixture. Background technique [0002] In the machining and manufacturing industry, the positioning and clamping fixture plays a very important role. It ensures that the workpiece is always in the correct position relative to the machine tool and cutting tool, and ensures the consistency and quality of the workpiece processing. [0003] Different types of workpieces have different requirements for the clamping fixture. When clamping the fixture on one side, it is easy to make the workpiece tilt away from the positioning point and destroy the positioning when clamping the fixture horizontally, resulting in unstable machining accuracy of the workpiece. In addition, common clamping Fixtures apply force to the surface of the workpiece to fix its position during processing, but the positioning effect on workpieces with internal gaps is not ideal. Therefore, a device that ...

[0003] Different types of workpieces have different requirements for the clamping fixture. When clamping the fixture on one side, it is easy to make the workpiece tilt away from the positioning point and destroy the positioning when clamping the fixture horizontally, resulting in unstable machining accuracy of the workpiece. In addition, common clamping Fixtures apply force to the surface of the workpiece to fix its position during processing, but the positioning effect on workpieces with internal gaps is not ideal. Therefore, a device that can position and clamp workpieces with internal gaps is urgently needed

Common clamping fixtures have the following disadvantages when positioning and clamping workpieces with internal gaps: 1. The adjustment of the pressure pressure is not strong when the surface is pressed and positioned, which is easy to cause damage to the workpiece; 2. One-sided pressure clamps It is difficult to achieve precise positioning of the workpiece during processing; 3. The structure of the traditional two-way clamping fixture mechanism is complex and the operability is poor
