Embodiment Construction

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, and Not all examples.

[0035] The centering structural parts to be processed in this embodiment refer to figure 1 , figure 2 and image 3 As shown, it includes a mandrel 10 with a large aspect ratio and a plurality of positioning sleeves 20 arranged at different distances on the mandrel, and a plurality of positioning protrusions and grooves are distributed on the positioning sleeve 20 along its circumferential direction. Form a gear-like structure.

[0036]The centering structure performs centering operation on multiple workpieces at the same time through multiple positioning sleeves arranged on the mandrel, so that e...

Abstract

The invention relates to the technical field of machining, and discloses a slender shaft-shaped centering structural part machining method which comprises the following steps: machining a positioning sleeve; processing a mandrel; assembling a centering structural member; machining a centering structural part; and the mandrel is positioned and clamped, and the outer contour surface of the positioning protrusion on each positioning sleeve is turned to the design size. According to the machining method, the centering structural parts are split, the core shaft and the positioning sleeve are independently machined, the machining thought that all the centering structural parts are split and then combined for machining is adopted, the machining steps in the machining process are adjusted, machining is more convenient, the requirement for machining equipment is not high, and machining efficiency is improved. And the machining precision of the centering structural part can be well guaranteed.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a processing method for a slender shaft-shaped centering structure. Background technique [0002] refer to figure 1 , is a centering tool that can be used to center multiple workpieces at the same time. There is good coaxiality between the workpieces used for fixing the projectile on the fixing device. The centering tool includes a mandrel and a plurality of positioning parts arranged along the axial direction of the mandrel, and the positioning parts are arranged on the mandrel at equidistant or unequal intervals. The structural feature of this centering tool is that a plurality of protrusions are arranged on the positioning member along its circumferential direction, and the outer contours of the multiple protrusions on the same positioning member are required to be located on the same circumference concentric with the mandrel. The protrusions provided on it co...
