Abstract

The utility model relates to a machine tool for milling threads on a casing tube. The utility model is designed for processing a taper thread casing tube which is used for connecting steel bars. The utility model is characterized in that a fast forward motor which is provided with a motor braking device on a machine tool body is controlled by a travel switch to feed and reset a headstock along bed ways by a leading screw pair. The headstock is provided with a stably-feeding motor which drives a main shaft and a workpiece to rotate by a worm gear pair, and the headstock is force by a speed changing mechanism and the leading screw pair to do stably-feeding movement. A cutter frame is provided with a cutting motor which drives a shaping cutter to rotate. All movements of the whole machine tool for milling threads on a casing tube are controlled and synergized by the travel stroke of the headstock and the front and the back sensors of the cutter frame. Automatic work is achieved, and the work efficiency and processing precision are raised.

Description

A kind of casing mill deduction bed
