Abstract

The invention provides a drilling machine, which includes a motor and a motor shaft, and also includes a drilling assembly, the drilling assembly includes a drill fixing part, a first drill and several adjustment drills, the first drill and The motor shaft is fixedly connected, the adjusting drill is coaxially nested on the first drill, the fixed part of the drill is provided with several rotating grooves, the adjusting drill and the rotating grooves are rotated in one-to-one correspondence, and the rotating The groove leaves a cylindrical space for adjusting the expansion and contraction of the drill, and the drill fixing part is provided with a bracket through the lower part, and the bracket is fixedly connected with the motor housing, and the drill fixing part is slidingly connected with the bracket through locking screws. The invention is used to solve the problem that different drills need to be replaced back and forth according to the requirements of different drilling apertures in the traditional drilling machine, and the problem of low efficiency.

Description

technical field [0001] The invention relates to the field of machining, in particular to a drilling machine. Background technique [0002] During mechanical processing, it is often necessary to perform drilling operations on the parts to be processed. Drilling will use rotary cutting or rotary extrusion to leave cylindrical holes on the parts to be processed. In the prior art, different rotor diameters need to be matched according to different drilling calibers. The size of the rotor is often fixed. When drilling between different diameters, it is necessary to replace the corresponding type of drill, and the work efficiency is low. Therefore, the present inventor has invented a kind of drilling machine that does not need to replace the drill, and directly realizes the drill diameter adjustment through simple operation under the situation of summarizing many years of industry experience. Contents of the invention [0003] The invention provides a drilling machine to solve ...
