Problems solved by technology

The internal pipeline in this method can only move in one direction, and cannot adjust in four directions at the same time, and the error after the pairing is completed is relatively large
At the same time, in this method, the two ends of the pipe cannot be operated synchronously, and the distance between the two ends of the inner pipe and the outer pipe needs to be adjusted repeatedly, and the coaxial pairing of the pipes takes a long time

Abstract

The invention provides a coaxial casing pipe assembling device and method. A die comprises an annular positioning ring, long adjusting devices and short adjusting devices. The annular positioning ring is of a cylindrical structure. The long adjusting devices and the short adjusting devices are evenly arranged on the two sides of the annular positioning ring in the circumferential direction at intervals and are fixed through clamps. The annular positioning ring and an outer casing pipe are positioned and connected through the short adjusting devices, and an inner casing pipe is adjusted and positioned through the long adjusting devices. According to the coaxial casing pipe assembling device and method, the structure is simple, operation is convenient, universality is high, precision is high, and repeated use can be achieved.

Description

technical field [0001] The invention belongs to the technical field of equipment installation, and in particular relates to a coaxial casing pairing device and method. Background technique [0002] Coaxial sleeve structures are commonly found on industrial pipelines or large equipment. In the wind tunnel structure, the coaxiality error between the wind tunnel body and the internal flow channel is a difficult point in the control of wind tunnel installation, and its coaxiality accuracy directly affects the quality of the flow field. [0003] The traditional large-scale casing assembly method is to take four symmetrical points on the end faces of the external pipe and the internal pipe, respectively draw the powder line on these four points to obtain the center of the pipe, and move the position of the internal pipe so that the internal and external pipes are separated by powder. The pipe centers drawn by the lines coincide. The internal pipeline in this method can only move...
