Manufacturing method of capsule filling parts for medical devices

Abstract

The invention discloses a manufacturing method for a capsule filling part of medical equipment. The method comprises the following steps of: using a rectangular sheet, positioning the rectangular sheet through the rough surfaces of a front side surface and an upper surface, clamping the rear side surface of the rectangular sheet, and machining two grooves with a milling cutter; performing positioning through one surface of a clamped position and two end surfaces, performing clamping through the other surface of the clamped position, polishing the upper surface, drilling on the upper surface, roughly machining bolt holes with a milling cutter, then semi-finishing the bolt holes, and polishing the upper surface in a finishing manner; performing positioning through the rear side surface and the upper surface which are machined, clamping the front side surface, and milling the lower surface; with a stop block, performing positioning through the rear side surface and the lower surface which are machined, clamping the front side surface with a stop block, grinding and machining the upper surface, performing backward rotation for 180 degrees, performing positioning and clamping again, and machining the lower surface; performing positioning through the rear side surface and the lower surface which are machined, clamping the front side surface, machining, semi-finishing and finishing capsule holes, and machining a dovetail groove and a retreat groove with a dovetail knife; and performing positioning through the rear side surface and the upper surface which are machined, clamping the middle surface and machining ejector rod holes. The hole diameter size, the surface finish and the hole diameter position accuracy are sufficiently guaranteed.

Description

technical field [0001] The invention relates to a manufacturing method of a capsule filling part of a medical device. Background technique [0002] For the capsule filling parts of medical equipment, the existing general processing methods must not only ensure the size of the aperture, the surface finish, but also the position of the aperture. It is difficult to guarantee the processing quality and processing efficiency in single-piece processing. The current processing technology only Can be processed in small batches. [0003] The inner hole of the capsule filling parts of medical equipment requires polishing. The step hole of the inner hole has the requirement of concentricity and verticality of 0.02, and the upper and lower surfaces have the requirement of parallelism and flatness of 0.01. The inner hole of the fine hole is processed by roller polishing, which is easy to produce knife lines and pits. Contents of the invention [0004] The purpose of the present inven...
