Abstract

The invention discloses a drilling and tapping combined tool for a threaded through hole. The tool comprises a drill bit body, and a drill bit and a screw tap are arranged at the front end of the drill bit body; and a narrowed transition part is arranged on the position, between the drill bit and the screw tap, of the drill bit body, a plurality of screw tap chip removal grooves are formed in thescrew tap, drill bit chip removal grooves corresponding to the screw tap chip removal grooves on the screw tap are formed in the drill bit and the transition part, and a knife handle is arranged at the rear end of the drill bit body. The drilling and tapping combined tool for the threaded through hole is reasonable in structural design, and belongs to the technical field of machining tools; the tool has the functions of drilling and tapping, and a drilling and tapping screw hole has high coaxiality precision; and the split drill bit and the screw tap are manufactured as the drilling and tapping combined tool, the drill bit and the screw tap are combined into one whole of the drilling and tapping combined tool, and the through hole threaded hole is machined through the buffering transitionof the transition part, so that the drilling and tapping combined tool has the functions of drilling and tapping.

Description

technical field [0001] The invention relates to the technical field of machining tools, more specifically, it relates to a combined drilling and tapping tool for threaded through holes. Background technique [0002] The threaded hole of existing processing through hole uses cutting tool to be to use drill bit to finish after threaded bottom hole processing earlier, then change screw tap cutter, and former hole tapping is completed. The whole screw hole machining process requires two kinds of tools, and the tool changing process increases the machining time. Contents of the invention [0003] The technical problem to be solved by the present invention is to address some of the above-mentioned deficiencies in the prior art. The purpose of the present invention is to provide a drilling and tapping function that has a higher coaxiality. High-precision threaded through-hole drilling and tapping combination tool. [0004] In order to achieve the above object, the present inven...
