Problems solved by technology

[0002] At present, when manufacturing medical devices, hexagonal shafts are used for power transmission. At present, when manufacturing hexagonal shafts, CNC centers are usually used to directly cut and shape the inner hexagonal shafts. However, the above-mentioned processes are rough during processing. Secondary rework is required after machining to ensure the smoothness of the inner hex shaft

Embodiment Construction

[0018] In order to deepen the understanding of the present invention, the present invention will be further described below in conjunction with examples, which are only used to explain the present invention and do not constitute a limitation to the protection scope of the present invention.

[0019] This embodiment provides a manufacturing process for the inner hexagonal shaft of a medical device, and the manufacturing process is as follows:

[0020] Step 1: Use a CNC lathe to turn and drill the left end face of the inner hexagonal shaft;

[0021] Step 2: Turning the outer circle of the inner hexagonal shaft, and performing three-feed cutting during turning;

[0022] Step 3: Groove the inner hexagonal shaft and cut off the inner hexagonal shaft. The length of the inner hexagonal shaft is 40mm;

[0023] Step 4: Deburring the inner hexagonal shaft with sharp edges and blunt left ends;

[0024] Step 5: Clamp the preliminarily processed inner hexagonal shaft on the CNC lathe wit...

Abstract

The invention provides a manufacturing process of a hexagonal shaft of a medical instrument. The left end face and the right end face of an inner hexagonal shaft are machined through a numerical control lathe, and the inner hexagonal shaft is subjected to sharp edge chamfering and burr removing immediately after each machining is completed, so that the smoothness degree of the inner hexagonal shaft is improved, the machining process effect is improved, the problem that the machining process of the inner hexagonal shaft can only be machined by using a numerical control center is solved, and the strength of the inner hexagonal shaft is improved by performing heat treatment and surface electrolysis treatment on the inner hexagonal shaft.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a manufacturing process for an inner hexagonal shaft of a medical equipment. Background technique [0002] At present, when manufacturing medical devices, hexagonal shafts are used for power transmission. At present, when manufacturing hexagonal shafts, CNC centers are usually used to directly cut and shape the inner hexagonal shafts. However, the above-mentioned processes are rough during processing. Secondary rework is required after machining to ensure the smoothness of the inner hexagon shaft. Therefore, it is particularly important to solve the problem that the machining process of the inner hexagon shaft can only be processed by the CNC center. Contents of the invention [0003] In order to solve the above problems, the present invention provides a manufacturing process for the inner hexagonal shaft of a medical device. The left and right end faces of the inner hexagonal...
