Tapping machine for small thread with tap breakage protection function

Abstract

Provides a tapping machine for small threads with the function of tap breakage protection, the output shaft of the motor is connected to the upper end of the main shaft in the main shaft part through a coupling; the lower end of the main shaft part is provided with a tapping torque protection part, and the motor drives the main shaft part and After the rotation of the tapping torque protection part, the tap clamped at the lower end of the tapping torque protection part rotates; the action end of the over-torque signal feedback device is connected to the tapping torque protection part, and the signal feedback end of the tapping torque protection part is connected to the main shaft; The main shaft part is connected with an operating handle, and the main shaft part is provided with a tapping depth limiting device for controlling the reverse rotation of the motor after the tapping depth is in place. The invention solves the problem of low efficiency in small thread tapping and the difficulty of setting the number of turns of the motor accurately to control its forward and reverse rotation, greatly improves the processing accuracy and production efficiency of small thread tapping, and realizes automatic tapping of small threads. Realize no broken tap phenomenon in the tapping process, reduce labor intensity and improve processing efficiency.

Description

technical field

[0001] The invention belongs to the technical field of tapping machines in mechanical processing, and in particular relates to a tapping machine for small threads with the function of preventing and protecting taps from breaking. Background technique

[0002] With the rapid development of science and technology, the processing capacity of modern industry is getting stronger and stronger. With the slogan of "Made in China 2025", China's manufacturing industry has higher and higher requirements for the processing accuracy and processing efficiency of parts. In daily work The problem of improving work efficiency is imminent. Many existing connectors need to be processed at both ends to realize the connection relationship with the other two main components. Traditional processing is single tapping, and tapping is almost the only completely feasible method for processing small screw holes. The process method, especially for the small-diameter screw holes of M1 ~ M...
