For decades, in the numerical control machine tool to high speed, efficient, precision, composite, intelligent, environmental protection direction drive, the corresponding fixture technology is headed in high precision, high efficiency, module, combination, general motors, and economic development. Fixture is indispensable mechanical processing one of the components. Commonly used several fixture mainly has: adjustable clamp; Modular fixture; Numerical control machine tool fixture, etc. And the economy is the most commonly used jaw the most popular a kind of fixture, its simple structure clamp rapid, accurate positioning and processing the save Labour when, improve the machining efficiency and machining accuracy. Improve the product quality. Mechanical processing, Taiwan is relatively common jaw clamped tool, it extension and hand in with two, all is the use two clamp mouth the locating datum, depends on the ball screw, nut mechanical transmission principle of work force. A simple structure jaw clamped rapidly, processing the save Labour when, improve the machining efficiency and machining accuracy. Improve the product quality. But a jaw also has its disadvantages. If not better clamp appearance is more complicated workpiece. The main reason is a jaw mouth is a flat clamps, is not suitable
