Aluminum tube machining mechanism for minimally invasive surgery

Abstract

The invention discloses an aluminum tube machining mechanism for a minimally invasive surgery. A plurality of first line slots and a plurality of second line slots are parallelly formed along the axial direction of a round slotting tool of the aluminum tube machining mechanism. Each of the first line slots consists of a first front line slot, a first back line slot and a first bent line slot; a bump is formed on the inner surface of an elastic sheet, and the bump is located at the tail end of the elastic sheet, so that a contact end surface is formed on the other end of the round slotting tool; left and right convex strips are arranged on the outer surface of the slotting tool, an inclined surface is arranged between the inner surface and the outer surface of an elastic blade, and a cutting edge is formed at the tail end of the outer surface of the elastic blade by virtue of the inclined surface; side cutting edges are formed on two sides of the first bent line slot and the second bent line slot; a compressing mechanism comprises a cylinder body, a piston and a cone-shaped cover; the cylinder body is hermetically and fixedly connected to the cone-shaped cover, the piston is mounted between the cylinder body and the cone-shaped cover, and the edge angle formed between the outer surface and the inclined surface of the elastic blade is 62 degrees. The mechanism disclosed by the invention can be in contact with the inner wall of an aluminum tube anytime without hurting the inner wall, small convex points on the inner wall can be removed to the maximum extent, and the effect is better.

Description

technical field [0001] The invention relates to the field of high precision machining, in particular to an aluminum tube processing mechanism for minimally invasive surgery. Background technique [0002] In the prior art, minimally invasive surgery is welcomed by patients because of its small trauma, light pain and quick recovery. However, due to the limitations of equipment and conditions, the operation has high requirements for doctors, but the process is very difficult. [0003] After long-term processing, it was found that the defect rate of micro-diameter aluminum tubes has been high, and most of the processed parts cannot meet the precision requirements. The main reason is that the extrusion material is poorly fed, and small bumps of 0.05MM~0.1MM often appear on the inner wall of the aluminum agent material. However, this phenomenon cannot be improved in the aluminum agent process and bumps cannot be avoided. Therefore, it is necessary to improve the subsequent proce...

Problems solved by technology

[0004] Due to the small diameter of the inner wall of this micro-caliber aluminum tube (5.86MM), there is still a tolerance and the inner wall has a special shape, and the special shape is very small (the width of the special shape is 0.7MM), and the small bumps on the inner wall cannot be removed by ordinary methods.
