在轴类零件的车削加工中,为了减少装卡零件辅助时间和减轻工人劳动强度,我厂设计、制造并使用了离心卡盘,如图1所示。离心卡盘主要由固定圆盘1和浮动圆盘2两部分组成。固定圆盘与主轴轴头连接,浮动圆盘在固定圆盘上浮动。浮动圆盘上的拨杆4和齿形卡爪3,通过离心力将零件预卡紧,加工时由切削力最后卡紧。离心卡盘见图2。其结构特点,即是利用旋转加工中离心力的作用卡紧零件,切削力与 In the machining of shaft parts, in order to reduce the auxiliary time for loading parts and reduce the labor intensity of workers, our factory designs, manufactures and uses centrifugal chucks, as shown in Figure 1. Centrifugal chuck mainly by the fixed disc 1 and floating disc 2 composed of two parts. The fixed disc is connected with the spindle shaft head, and the floating disc floats on the fixed disc. Lever on the floating disc 4 and the toothed claw 3, the parts pre-clamping by centrifugal force, the processing force by the cutting force last card. Centrifugal chuck shown in Figure 2. Its structural features, that is, the use of centrifugal force in rotating machining clamping parts, cutting force and
