Processing method for cylindrical turning of arc plate assembly

Abstract

The invention discloses a processing method for cylindrical turning of an arc plate assembly which is specifically implemented according to the following steps: firstly, processing a first clamping position at one end of each arc plate and processing a second clamping position at the other end thereof, wherein when all arc plates are cylindrically assembled, all the first clamping positions constitute a first cylindrical end and all the second clamping positions constitute a second cylindrical end; secondly, after all the arc plates are cylindrically assembled to form an assembly, using a clamping body to clamp the first cylindrical end and fastening the second cylindrical end into a blind hole in one side of a top plate; and finally, loading the assembly clamped by the clamping body and the top plate into a machine tool and performing cylindrical cutting on the surface thereof according to a set radian. By adopting the method, the problems that workpieces are unstable, easy to deformand have difficulties in loading, clamping and alignment when the arc plates are processed as a whole, and the workpieces are easy to spread during processing are solved.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, and in particular relates to a processing method for turning an outer circle with arc-plate combination. Background technique [0002] During the production and operation of petroleum equipment products, especially marine equipment products, many structures of arc plates or arc blocks are used. Due to the particularity of some materials and structures (such as marine riser buoys, which are made of brittle materials and have a huge structure), the arc plates can only be in the shape of arc plates after blanking, and these arc plates often need to be spliced ​​together during work. A full circle is required. [0003] In the process of single-piece processing of such large circular arc plates, intermittent cutting often occurs, which makes it easy to form obvious bosses at the joints of each arc plate after assembly, so that the outer circle after splicing will be There are irregular...
