Steel structure drilling machine facilitated to disassembling and assembling drill bit

Abstract

The invention discloses a steel structure drilling machine facilitated to disassembling and assembling a drill bit. The steel structure drilling machine comprises a base. A supporting column is fixedly connected to the right side of the top of the base, a top plate is fixedly connected to the top of the supporting column, an air cylinder is fixedly connected to the left side of the top of the topplate, the bottom of the air cylinder penetrates through the top plate and extends to the exterior of the top plate to be fixedly connected with a rotating motor, and a rotating shaft is fixedly connected to an output shaft of the rotating motor. According to the steel structure drilling machine facilitated to disassembling and assembling the drill bit, through mutual cooperation of clamping grooves, fixing shafts, supporting plates, clamping blocks, supporting springs, semicircle rings, first grooves, second grooves, first pulleys, bearing seats, first rotating shafts, driven bevel gears, rolling barrels, second rotating shafts, driving bevel gears, first handles, limiting holes, threaded grooves, threaded rods, second handles, and steel wire ropes, the action of facilitating to disassembling and assembling the drill bit is played, the disassembly and assembly process is simple, the time and labor are saved, the labor intensity of users is relieved, the drilling efficiency of the drilling machine is improved, and great convenience is brought to the users.

Description

technical field [0001] The invention relates to the technical field of steel structure processing, in particular to a drilling machine for steel structures which is convenient for disassembling and assembling drill bits. Background technique [0002] Steel structure is a structure composed of steel materials. It is one of the main types of building structures. Chemical, washing and drying, galvanizing and other rust removal and antirust processes, the components or parts are usually connected by welds, bolts or rivets, because of their light weight and easy construction, they are widely used in large factories, venues, super high-level fields. The common drilling machine for steel structure is not easy to disassemble and assemble the drill bit. When the drill bit is damaged and needs to be replaced, it takes a lot of time and energy to disassemble and assemble, which not only increases the labor intensity of the user, but also seriously affects the drilling. The drilling e...
