Apparatus and method for compound turning of inner and outer circular end faces of thin-walled ellipsoid

Abstract

The invention provides a thin-walled ellipsoid top inner and outer circular end surface composite turning processing device and method, comprising: a lower disc 1, a support vertical bar 2, an upper disc 3, a support inner tube 4, a compression ring 5 and a pressing The support vertical bar 2 is supported and connected between the lower disc 1 and the upper disc 3; the support inner tube 4 is connected to the upper surface of the upper disc 3 as a thin-walled ellipsoidal top The inner profile support; the pressing member is connected to the pressing ring 5; the pressing ring 5 is located on the outer profile side of the thin-walled ellipsoidal top, and under the action of the pressing member, it can be The outer profile side of the thin-walled ellipsoidal top exerts pressure on the inner profile side, and the thin-walled ellipsoidal top is compressed on the supporting inner tube 4 . It not only guarantees the machining accuracy of the product, but also realizes the turning of the inner and outer circular end faces of the product in one quick changeover, which not only ensures the turning accuracy of the product, but also improves the processing efficiency, effectively ensuring the quality and progress of model research and production.

Description

technical field [0001] The invention relates to the field of mechanical processing, in particular to a device and method for compound turning of the inner and outer circular end faces of a thin-walled ellipsoid. Background technique [0002] Just as patent document CN107900509 discloses a kind of tooling and method for matching the bottom circular ring and the transition ring of the rocket storage tank, the bottom of the launch vehicle storage tank is an ellipsoidal structure, that is to say, the structure of the top cover of the tank bottom is a thin-walled ellipsoidal top structure, and the top The outer round end face of the cover needs to be welded with the ring, and there is an assembly angle; the inner round hole of the top cover needs to be welded with a flange; the inner and outer round end faces of the top cover are completed by turning. However, in the current existing technology, both the inner and outer circles of the top cover are processed by cutting technology...

Problems solved by technology

However, in the current existing technology, both the inner and outer circles of the top cover are processed by cutting technology, and 36 clamping plates are implemented in the margin range of the outer ring of the product for clamping. The clamping efficiency is not high, and the angle of the cutting end face of the product cannot meet the requirements. Weld assembly angle
