Novel semi-automatic feed mechanism of threading machine

Abstract

The invention discloses a novel semi-automatic feed mechanism of a threading machine. The novel semi-automatic feed mechanism comprises a thread cutting device, a gear box, a main shaft, a sliding machine base, a speed reducer, a motor, a worm pair and round guide rails. According to the thread cutting device, four movable threading die type cutters are installed in a cylindrical cutter supportingframe, one end of the thread cutting device is connected with the main shaft through a coupler, the gear box is arranged between the thread cutting device and the sliding machine base and fixed to one end of the sliding machine base, the main shaft is a driven wheel output shaft in the gear box and fixedly connected with a driven wheel through a key groove structure, the sliding machine base is arranged at one end of the gear box, the two round guide rails are arranged at the bottom end of the sliding machine base, and the sliding machine base is connected with the round guide rails in a clearance fit mode through shaft sleeves. According to the novel semi-automatic feed mechanism of the threading machine, a worm mechanism is adopted as motion and power output of thread cutting, and meanwhile the advantages that an original machine is high in machining efficiency, small in size, compact in structure, low in weight, capable of facilitating field machining and the like are kept.

Description

technical field [0001] The invention relates to a mechanical cutting tool, in particular to a novel semi-automatic tool feeding mechanism of a threading machine. Background technique [0002] In the process of using the threading machine, the manual advance and retreat method was found to be labor-intensive, the quality of thread processing was unstable, and the thread profile often had bald teeth, wide bottoms, and disordered teeth, etc., which were affected by the operator's proficiency, fatigue, and Subjective factors such as emotions have a great influence. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a new type of semi-automatic knife feeding mechanism for threading machine aiming at the above problems. [0004] In order to solve the above technical problems, the technical solution provided by the present invention is: a new type of semi-automatic feeding mechanism for threading machine, including thread...
