我厂生产的轴类零件以φ20～φ60mm为主,为使这些轴类零件在车削加工中能快速装夹,减少辅助工时,我们设计制造了一种夹具如图所示,并已按零件尺寸的不同,制成一系列。该夹具结构简单,使用方便,能在高速旋转中装夹工件,生产效率高、安全可靠。经一年多的使用证明,它的生产效率比卡盘装夹工件提高两倍以上,它适用于各厂矿企业中批量和大批量生产轴类零件。该夹具由螺塞1、弹簧2、顶尖3和夹具体4所组成。未装工件时,顶尖3的尖端在弹簧2的作用下,位于夹具体4的锥孔孔口。开车后,先将工件一端的顶针孔与顶尖3对准,然后将工件另一端的顶针孔与
I produced the shaft parts φ20 ~ φ60mm mainly in order to make these axis parts in the turning process can be quickly installed to reduce the number of auxiliary work hours, we designed and manufactured a fixture as shown, and has been part size Different, made a series. The fixture has the advantages of simple structure and convenient use, and can clamp workpieces in high-speed rotation, and has the advantages of high production efficiency, safety and reliability. After more than a year of use proved that its production efficiency than chuck chuck workpiece more than doubled, it is suitable for the factories and mines in the batch and mass production of shaft parts. The fixture consists of a plug 1, a spring 2, a tip 3 and a clamp body 4. When the workpiece is not installed, the tip of the top 3 under the action of the spring 2 is located in the taper hole of the clamp body 4. After driving, first one end of the thimble hole and the top 3 aligned, and then the other end of the thimble hole and
