Threaded hole drilling and tapping machine

Abstract

The invention discloses a threaded hole drilling and tapping machine which comprises a rack. A linear guide rail is arranged at the top of the rack, a linear bearing is arranged on the linear guide rail, the top of the linear bearing is connected with a connecting steel plate, a single-phase double-speed motor is arranged on the connecting steel plate, a lengthened cutter clamp is arranged on an output shaft of the single-phase double-speed motor, and a drilling and tapping composite cutter is arranged at the front end of the lengthened cutter clamp, the output shaft of the single-phase double-speed motor is connected with a differential screw mechanism through a gear transmission mechanism, and the differential screw mechanism is arranged on the rack and used for driving the connecting steel plate. A drill tool does not need to be held manually to control hole drilling and tapping in the machining process, and therefore quality fluctuation caused by previous manual operations is avoided, and machining quality is improved. One motor can provide power for hole drilling, tapping and feeding at the same time, and therefore one motor is saved. The recoil problem in the hole drilling and tapping process is solved, the work process is more stable, and therefore hole drilling and tapping quality is improved.

Description

Technical field [0001] The invention relates to a drilling and tapping equipment, in particular to a special drilling and tapping machine for threaded holes of passenger car seats. Background technique [0002] At present, the position of the car seat installation varies with customer requirements and needs to be adjusted in time. Therefore, when the steel plates on both sides of the carriage cannot be installed, threaded holes must be reserved on the steel plates. Therefore, most of the threaded holes of passenger car seats are processed after the carriage is installed and formed. According to the user's requirements, the holes are marked on the spot, and the holes are first processed by manual power tools and then tapped. Because the hole is close to the bottom of the carriage, the working space is small, and large-sized equipment cannot be used, and it is difficult to use the drilling and tapping composite tool. The hole can only be manually bent and then drilled and then tapp...

AI Technical Summary

Problems solved by technology

Because the hole is close to the bottom of the carriage, the working space is small, and it is impossible to use large-sized equipment, and it is also difficult to use a drilling and tapping compound tool. It can only be manually bent down, drilled, and then tapped.

Workers bend over a lot when drilling, and sometimes the number of seat mounting threaded holes on each car is as many as dozens, and the hole diameter is relatively large, usually M8, which results in high labor intensity for workers and difficult processing Easy to fatigue during the process, and the processing efficiency is very low

Hand-held drilling tools and other tools are used for drilling and tapping. The processing quality is good or bad, and the processing quality is even wor
