A precision equipment pipe docking centering device

Abstract

The invention relates to the technical field of pipe butt, and discloses a precision equipment pipe butt centering device. The precision equipment pipe butt centering device comprises a shell, whereineight limit pipes are inserted outside the shell, and the four of the eight limit pipes are symmetrically distributed as a group; pressure plates are welded on the tops of the limit pipes; the tops of the pressure plates are provided with openings communicating with the limit pipes; the bottoms of the pressure plates are rotationally connected with turntables; and the turntables are annular. By means of the precision equipment pipe butt centering device, adjusting springs are installed between top rods and connecting blocks, adjusting rods are pressed into slots during using, at the moment, compression grooves are at the same level with clamping rods, then the top rods are pressed downward, thus, the clamping rods are pressed into the compression grooves through the curved surfaces duringmoving with the top rods, and according to the model of a butt pipe, the top rods are moved to the application positions, so that the top rods compress the adjusting springs to apply a pre-applied force to the connecting blocks, the self weight of the pipe is offset, and therefore, the centering error is reduced and the quality of a product is ensured.

Description

technical field [0001] The invention relates to the technical field of pipeline butt jointing, in particular to a precision equipment pipeline butt joint centering device. Background technique [0002] In the fields of road construction or manufacturing, there will be pipe butt joints. In order to ensure the quality of pipe joints, workers will use centering devices to ensure that the two pipes are on the same center line. [0003] The traditional centering device installs four springs with the same elastic force outside a casing. One end of the spring is connected to a splint. After being inserted into the pipe, the surroundings of the pipe receive the same thrust, which can play a centering role. [0004] When performing some high-precision pipe butt joints, due to the self-weight of the pipe, the spring under the pipe will receive the reaction force of the pipe and the gravity of the pipe at the same time, which may cause errors in the centering results and affect the doc...

[0004] When performing some high-precision pipe butt joints, due to the self-weight of the pipe, the spring under the pipe will receive the reaction force of the pipe and the gravity of the pipe at the same time, which may cause errors in the centering results and affect the docking effect. Therefore, we propose a precision equipment pipe butt joint centering device to solve the problem
