Inner drilling device for processing thin-wall tube member

Abstract

The invention discloses an inner drilling device for processing a thin-wall tube member. The inner drilling device comprises a cutter feeding device for achieving vertical drilling from inside to outside and a sliding base device for driving a clamped processing member to slide in linear mode. The processing member is a thin-wall tube member, and the cutter feeding device comprises a pneumatic angular drill, a center regulating bearing base for fixing and performing swinging center adjusting on the pneumatic angular drill and a threaded pneumatic cylinder, wherein the pneumatic angular drill comprises a drill bit and a drill rod, and the drill bit can extend into the inner tube of the processing member; a center regulating bearing is embedded into the center regulating bearing base, and the drill rod is sleeved in a bearing hole of the center regulating bearing in penetrating mode; and the threaded pneumatic cylinder is used for controlling the drill rod to swing with the center regulating bearing base as the lever fulcrum to enable the drill bit to perform drilling. The inner drilling device can achieve the drilling depth of inner hole drilling accurately and prevents the inner tube of the thin-wall tube member from deforming during processing, the processing process can be finished in one step, the processing procedure is easy, and the hole forming accuracy is high.

Description

technical field [0001] The invention relates to an inner drilling device, in particular to an inner drilling device for processing thin-walled cylindrical parts. Background technique [0002] The usual processing method of the oil hole of the cylinder part of the automobile steering gear is to drill the hole with a drilling machine, then use a pneumatic tool to repair the burr, and then use a ball end grinding tool to grind the shape of the inner hole or use a steel ball mold in the press Press molding. Although the above-mentioned processing method is feasible, it needs to be processed in three times, and manual deburring with pneumatic tools is likely to cause roughening of the inner wall of the cylinder, and pressing and forming on a press may cause deformation of the cylinder. Therefore need to seek a kind of method to solve above-mentioned technical difficult problem. Contents of the invention [0003] The technical problem to be solved by the present invention is t...
