Single side broaching involute internal spline deburring broach

Abstract

The invention discloses a unilateral broaching involute internal spline deburring broach which comprises a front handle, a transition cone, a guide key, spline cutting teeth, a round tooth part and a rear handle which are connected in sequence, wherein the guide key, the spline cutting teeth and the round tooth part are in linear connection with the same axis; the guide key has the function of guiding and tooth aligning; the spline cutting teeth have the function of unilateral broaching for flange deburring; the round tooth part has the function of shaping and ending; the spline cutting teeth comprise multiple identical spline teeth; each spline tooth comprises a left side face and a right side face; each left side face is a broaching tooth with rise and the edge inclination of 30-40 degrees, and the blade belt of the cutting tooth of each left side face is 0.1-0.2; each correction tooth blade belt is 0.1-0.2; each right side face is a positioning tooth without rise, and the positioning surface of each positioning tooth and that of the guide key are in the same plane.

Description

technical field [0001] The invention relates to a single-side broaching involute internal spline deburring broach, which can realize the removal of flanging burrs on the tooth side of the internal spline caused by the turning process, and belongs to the field of mechanical processing tools. Background technique [0002] With the mass production of parts, the problems of low efficiency and unstable quality of manual deburring have become more and more obvious. The demand for mechanical deburring has become increasingly urgent. Its high production efficiency, stable quality, and low processing cost of a single part fully meet the needs of batch production parts. requirements. [0003] At present, the single-side flanging burrs remaining in the turning process are manually deburred. The production efficiency is low and the removal is not complete. The flanging burrs are often left on the top side of the tooth. The edge burr produces extrusion stress on the side of the broach t...

Problems solved by technology

[0003] At present, the single-side flanging burrs remaining in the turning process are manually deburred. The production efficiency is low and the removal is not complete. The flanging burrs are often left on the top side of the tooth. The edge burr produces extrusion stress on the side of the broach tooth, causing a slight deflection of the workpiece, resulting in a pull-off phenomenon that causes the tooth side to be rough, and even causes the adverse consequences of the workpiece being directly scrapped
