过去,我厂在C618车床上加工各种带锥度的零件时,一般都是用手摇刀架小拖板来进行切削的。这不仅效率低,而且加工质量也差。为了解决这个矛盾,我们革新成功车锥度自动走刀装置,安装在C618车床刀架部分,经使用证明,效果比较满意。现将结构介绍如下。本装置结构如图所示。使用时,只需卸下原转盘以上的部件,换上本装置,调整好锥度。然后,启动电机按钮,运动经蜗轮副14减速后传递给丝杆11,使旋转运动变成直线运动,借助原螺母2的作用,使蜗轮箱拖板3连同刀架实现自动走刀运动。刀具需退 In the past, I plant in the C618 lathe machining a variety of parts with taper, the general is to use the hand-knife carriage for cutting. This is not only inefficient, but also poor in quality of processing. In order to solve this contradiction, we innovatively succeeded in turning the car taper automatic cutting device, installed in the C618 lathe turret part, the use of proof, the effect is more satisfactory. The structure is introduced below. The device structure as shown. Use, just remove the original turntable above the components, put on the device, adjust the taper. Then, the motor button is started, and the movement is transmitted to the screw rod 11 after being decelerated by the worm gear pair 14 to make the rotation movement into a linear motion. With the action of the original nut 2, the worm-gear box carriage 3 together with the knife holder realizes the automatic knife movement. Tools need to retreat
