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 drilling and tapping equipment, in particular to a special drilling and tapping machine for installing threaded holes in passenger car seats. Background technique [0002] At present, the installation position of the passenger car seat varies with the customer's requirements and needs to be adjusted in time. Therefore, it is impossible to reserve threaded holes on the steel plates when installing the steel plates on both sides of the car. Therefore, most passenger car seat installation threaded holes are processed after the carriage is installed and formed, according to user requirements, on-site marking, manually using manual power tools to process the holes first, and then tapping. 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...

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 worse after the workers are tired.

[0003] In the prior art, a drilling motor is needed to provide power for drilling, but the drilling motor cannot drive the drilling device to realize the feeding motion, and a feeding motor is needed to drive the drilling device to complete the feeding motion

[0004] In the prior art, during manual drilling and tapping, the drilling tool will also transmit the recoil force to the operator, and the recoil force will make the operator unable to work stably, thereby reducing the quality of drilling and tapping

[0005] At present, there is a lack of threaded hole drilling and tapping machines that can reduce the labor intensity of workers, improve processing efficiency and processing quality, and have low cost in the market.
