我厂加工花键孔时,没有拉床,为节省设备投资,将C630车床附加一套拉削装备。使用后效果良好,加工精度达到二级。这种装备扩大了车床加工范围,适用于小批量生产。现介绍如下:一、结构特点装备结构如图所示,由主轴传动部分与主体部分组成。主轴传动部分由传动套 3、保险块 2、T形键19及螺钉4组成,作为装备的附件,使主轴传递扭矩。主体部分与丝杆拉床相似。螺母5固定在主体床身12上,当主轴回转时,传动丝杆1和支承套17与车床主轴同步回转,并作直线移动,推动导向座8和
I plant processing spline hole, no broaching, to save equipment investment, the C630 lathe additional set of broaching equipment. Good effect after use, processing accuracy reached two. This equipment expands the lathe processing range, suitable for small batch production. Are introduced as follows: First, the structure and characteristics of equipment as shown in the figure, the main part of the drive shaft and components. Spindle drive part of the drive sleeve 3, the fuse block 2, T-shaped keys 19 and screws 4 components, as an attachment to the spindle to transmit torque. The main part of the wire rod broaching similar. Nut 5 is fixed to the body bed 12, when the spindle rotates, the drive screw 1 and the bearing sleeve 17 and the lathe spindle synchronous rotation, and make a straight line to move the guide seat 8 and
