我厂的车床,都是英制的。车削公制螺纹时,曾经采用过几种方法,都不够满意。后来,老工人邬德甫同志利用一部四呎半的英制车床,在原来的丝杠上安装公制的方牙螺套,另在横走刀架的侧面装上半部闸瓦的操纵机构,利用这样一套辅助装置,便能车削长度在150公厘以内的内外螺纹。经实际使用,质量符合要求,解决了我厂过去车削公制螺纹的困难。装置的结构如下:用两只六角螺钉将基座8固定在横刀架的左端或右端(按车(?)横刀架的结构决定),在基座8上安装公制半部闸瓦4、连杆3、操纵手柄1、
I plant the lathe, are British. Turning metric threads, there have been several methods used, are not satisfied. Later, Comrade Wu De-fu, an old worker, used a four-and-a-half inch imperial lathe to install a metric square screw nut on the original lead screw and another half brake shoe operating mechanism on the side of the crosscutter A set of assistive devices allows the turning of internal and external threads up to 150 mm in length. The actual use of quality to meet the requirements to solve the factory in the past turning the metric thread difficulties. The structure of the device is as follows: the base 8 is fixed on the left end or the right end of the transverse turret by two hexagonal screws (determined according to the structure of the horizontal turret of the car), a metric half of the brake shoe 4 is installed on the base 8, Connecting rod 3, joystick 1,
