为了加工带锥度工件,我们革新成功了一种结构简单、使用方便的车削锥度装置(附图)。这种车锥度装置安装在C620车床大拖板后部。它主要是把C620的横走刀丝杠改为轴齿轮1和丝杠4的两部分;此外,该装置还包括其它零件。轴齿轮1上的齿轮和拖板箱内的横向自动走刀齿轮啮合,起横向自动走刀作用。它的一端有一φ20的键槽孔,另一端穿过支架2和手柄相连。丝杠4一端套入
In order to work with taper workpieces, we succeeded in turning a simple, easy-to-use turning taper (photo). This car taper mounted on the back of the C620 lathe pallet. It is mainly to the C620 horizontal knife screw to shaft gear 1 and screw 4 in two parts; In addition, the device also includes other parts. The gear on the shaft gear 1 is meshed with the horizontal automatic walk gear in the pallet, which acts as a horizontal automatic walker. It has a φ20 keyway hole at one end, and the other end through the bracket 2 connected to the handle. Screw 4 into one end
