Dual-purpose drilling machine used for drilling threaded holes in automobile metal castings

Abstract

The invention discloses a dual-purpose drilling machine used for drilling threaded holes in automobile metal castings. The dual-purpose drilling machine comprises an upper frame, wherein the two sides o the bottom of the upper frame are provided with stand columns; slide slots are formed inside the stand columns; pulleys are fixedly arranged in slots of the slide slots; the inner sides of the pulleys are connected with another pulley through a slide rod; a slide wheel rack is mounted on the top of the slide rod; a fixed pulley of the pulley rack is separately connected with another fixed pulley and a winding machine through a steel wire rope; the bottom of the slide rod is provided with a rotary motor; the output shaft of the rotary motor is connected with a rotary rod; the bottom of the rotary rod is connected with a drill pipe; the outer side of the drill pipe is provided with a milling cutter in a sleeved manner; and the bottom of the drill pipe is provided with a drill bit. According to the dual-purpose drilling machine used for drilling threaded holes in automobile metal castings, the integer is matched with the winch through the pulley set, and a drilling tapping device is driven to move, so that the integer is controlled to drill and tap simultaneously, and therefore, the drilling and the tapping are more convenient.

Description

technical field [0001] The invention relates to the technical field of auto parts processing, in particular to a dual-purpose drilling machine for opening threaded holes in auto metal castings. Background technique [0002] In the field of auto parts processing, automotive metal castings account for a large proportion, and when metal castings are processed, metal castings are usually connected to other parts through threaded connections. The threaded connection of metal castings needs to be opened on the surface of the metal castings first. The hole is then tapped, so that the threaded hole for connection can be completed to facilitate the connection between automotive metal castings. [0003] At present, most of the drilling machines on the market are small in size, slow in drilling speed, slow in power output, and low in work efficiency. The metal casting is moved to the tapping machine to open the internal thread to complete the overall work, which wastes a lot of workin...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the drilling machines on the market are small in size, slow in drilling speed, slow in power output, and low in work efficiency. The metal casting is moved to the tapping machine to open the internal thread to complete the overall work, which wastes a lot of working time, which is not conducive to the rapid completion of the processing of the metal casting, and is not suitable for popularization and use.
