分度转台用于多工位冲压时,其刚度和定位的稳定性对制件的精度影响很大。棘轮分度转台因为冲击大,定位不稳定,刚性差,当制件精度要求较高时一般不采用。但是,由于这种转台结构简单实用,制造成本低,我们在低精度棘轮转台的基础上作了改进,试制了一种冲击小.性能较好的棘轮分度转台,已投入生产使用,效果很好。现介绍如下: 结构如图1所示,冲床滑块上升时,摇杆4驱动棘爪机构带动转盘15顺时针旋转,
Indexing turntable for multi-station stamping, the stiffness and positioning of the stability of precision parts have a great impact. Ratchet indexing turntable impact because of large, unstable positioning, poor rigidity, when the workpiece accuracy is generally not high. However, due to its simple and practical structure and low manufacturing cost, we made improvements on the basis of low-precision ratchet turntables and tried out a ratchet indexing turntable with low impact and high performance, which has been put into production it is good. Now introduce as follows: The structure is shown as in Fig. 1, when the punch slider rises, the rocker 4 drives the pawl mechanism to drive the turntable 15 to rotate clockwise,
