连杆零件机械加工工艺及加工小孔钻夹具设计（有CAD图纸）.pdf

Machinery manufacturing industries in the process of a wide variety of applications for processing a fixed object, so that it occupies the correct position in order to receive a construction technology and equipment, collectively referred to as the fixture. Therefore, whether in the machinery processing, assembly, testing, or in welding, heat treatment, such as cold, heat process, and transport are a lot of work in a fixture. But in machining is the most widely used metal-cutting machine tools for use on the fixture, we called for the machine tool fixture. It guarantees high-quality products, high-yield, low-cost, bring into full play the potential of existing equipment, so that
