台虎钳设计说明书
摘要：机械是人类生产劳动的重要工具。
几十年来，在数控机床向高速、高效、精密、复合、智能、环保方向发展的带动下，相应的夹具技术正朝着高精、高效、模块、组合、通用、经济方向发展。夹具是机械加工不可缺少的部件之一。常用的几种夹具主要有：可调夹具；组合夹具；数控机床夹具等。而虎钳是最常用最经济最普及的一种夹具，其结构简单装夹迅速，定位准确，加工时省时省力，提高了加工效率和加工精度。提高了产品质量。
机械加工中，台虎钳是较为常见的装夹工具，它分机用和手用两种，都是利用两钳口作定位基准，靠丝杠，螺母传送机械力的原理进行工作的。台虎钳结构简单装夹迅速，加工时省时省力，提高了加工效率和加工精度。提高了产品质量。但是台虎钳也有其不足之处。如不能较好的装夹外形较为复杂的工件。主要原因是台虎钳钳口是平直的，不适于装夹圆柱形工件，机加工时工件易位移，有时工件还会飞出机床台面。为此，特对台虎钳的钳口进行结构的改进设计。以满足更多使用功能的要求，使其更加的实用化。

ABSTRACT：Machinery is the important tool of human productive labor.
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 Labor 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 Labor 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 for the clamping cylindrical work pieces, machining the easy when the displacement, sometimes workpiece will also fly out of the machine tool mesa. Therefore, to Taiwan, the jaw structure improvement of mouth clamp design. In order to meet the requirements of the more use function, make it more practical.
