I plant in the belt lathe screw system, due to excessive movement of the large pallet, the bed is often worn out groove, not only very tired to operate, and the car out of the screw finish is not high, especially in the metric lathe metric Screws more difficult. According to the above-mentioned situation, the worker Jing Wenxiu improved a set of live-setting top-threading tools to solve the above problems. The structure and use of this tool is as follows: The tool consists of seven parts (see Figure 1). 4 is the die-moving frame. Boss hole seat according to the die diameter outside the car, two for sliding fit. After the teeth are tightened by fastening screws. The back of the plate, with two
