Flexible joint machining method

Abstract

The invention discloses a flexible joint machining method. The flexible joint machining method comprises the following steps that a bar is mounted on a turning main shaft of a turning and milling composite machine tool, and the outer circumferential surface of the bar is turned; four planes evenly distributed in the circumferential direction of the bar are milled on the outer circumferential surface of the bar through indexing of the turning main shaft; two semicircular holes are correspondingly milled in each plane, and semicircular arc openings of the two semicircular holes in each plane are opposite; the semicircular arcs of the semicircular holes in the planes are correspondingly bored; a through hole is formed in the center of the second end of the bar; broaching is carried out at the end, corresponding to the second end of the bar, of the through hole; threads are machined on the hole wall of the broached hole; the first end of the bar is turned; and the first end of the bar is cut off. The turning and milling composite machine tool is used for machining a flexible joint, all cutting machining of the flexible joint can be completed in one-time clamping, errors caused by secondary clamping are eliminated, the machining precision of the flexible joint is improved, the grinding and adjusting procedures in the traditional technology are eliminated, the machining time is greatly shortened, and the machining efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of flexible joint processing, in particular to a flexible joint processing method. Background technique [0002] The flexible joint is the key part in the moving gyro. refer to figure 1 As shown, the flexible joint mainly includes a thick shaft and a thin shaft 7 arranged coaxially with the thick shaft. The circumferential surface of the thick shaft is machined with four planes 3, and the four planes 3 are evenly distributed along the circumference of the thick and thick shaft. Each plane is provided with a thin-necked and thin-walled structure 5 . The thin-necked thin-walled structure 5 is mainly formed by two symmetrically arranged semicircular holes 4 , and the opening directions of the semicircular arcs of the two semicircular holes 4 are opposite. The outer circumferential surface of the end of the thick shaft away from the thin shaft 7 is further provided with a thin groove 6 . The consistency of t...

Problems solved by technology

Therefore, the parts obtained by this processing method cannot be put into use directly, and need to be manually measured and ground repeatedly in the later stage.

Therefore, the processing technology of flexible joints in the prior art has problems such as large processing errors, low efficiency, high cost, and poor quality.

How to solve the problems of large processing errors, low efficiency, high cost and poor quality in the processing technology adopted in the prior art is a technical problem that those skilled in the art need to solve urgently
