Clamp

Abstract

The invention belongs to the technical field of processing. In the prior art, different clamps are used, special clamps are needed for changing different parts, the complex and high-cost clamps have low shock resistance, and after installation, the clamp has low positioning precision and low working efficiency. The invention provides a clamp. According to the clamp, cushion blocks are movably hinged below a clamp holder; the lower plane of the clamp holder has two inclined planes arranged in a V shape; a big clamp block is arranged on the clamp holder by left and right cushion blocks; small cushion blocks are arranged on the two V-shaped faces of the big clamp block; the big clamp block and the small clamp block both have a V-shaped opening and are symmetrically distributed; a supporting block is arranged on the side face of the big clamp block; a fixed block is arranged on the supporting block; and the small clamp block is connected to the fixed block by threads. When used, the clamp can reduce vibration and increase clamping precision; and the clamp can be used for clamping different workpieces and therefore increases working efficiency considerably, and the clamp has the characteristics of low cost, wide application range and the like.

Description

technical field [0001] The invention belongs to the technical field of processing, and in particular relates to a clamp. Background technique [0002] In modern processing technology, there are many types of fixtures for clamping. When replacing different types of parts, it is often necessary to replace the corresponding special fixtures. The structure of various fixtures is complex and the cost is high. The shock resistance of various fixtures is not good. The precision is low. When the workpiece is long, it is necessary to install the center frame and the fixture at the same time. The clamping and centering of the workpiece are complicated when the workpiece is installed, and the center of the workpiece needs to be re-aligned after each clamping, and the work efficiency is low. Contents of the invention [0003] The purpose of the present invention is to overcome various deficiencies of existing fixtures, and provide a fixture with simple and quick installation, high pos...
