一般车床加工,要经过停车、装工件、夹紧、开车、切削等手续,辅助时间很长。我厂技师沈维璋同志,在这次技术革新中,设计了一种离心力夹具。它的特点是制造简单、成本低、精度高、使用很方便,它的结构见右图。把工件放进夹具,不要夹紧就能开车。夹具在高速旋转时所产生的离心力将夹爪1涨开而自动把工件夹紧。停车后失去离心力,因弹簧4的作用迅速使夹爪收缩,工件就可以取出,装夹时间只要几秒钟。这种夹具适用于小型另件的成批生产。现在介绍的夹
General lathe processing, to go through parking, loading workpieces, clamping, driving, cutting and other procedures, aids a long time. Shen Wei-chang factory technician comrades, in this technological innovation, the design of a centrifugal force fixture. It is characterized by simple manufacturing, low cost, high precision, easy to use, its structure, see the right. Put the workpiece into the fixture, and drive without clamping. Centrifugal force generated when the jig rotates at high speed will open the jaws 1 and automatically clamp the workpiece. After stopping the loss of centrifugal force, due to the role of the spring 4 to quickly shrink the jaws, the workpiece can be removed, clamping time as long as a few seconds. This fixture is suitable for mass production of small parts. Now introduce the folder
