Abstract

The invention discloses a large-sized spherical structure element heat treatment deformation measuring device, which comprises a spherical structure element, a measuring base plate, a laser tracking instrument and four target seats, wherein the spherical structure element is formed by an upper semicircular spherical block and a lower semicircular spherical block through welding; an annular weldingseam is formed between the two semicircular spherical blocks; the measuring base plate is placed under the semicircular spherical block positioned at the lower layer; a first station and a second station are symmetrically arranged at two sides of the measuring base plate; the first station and the second station are connected through an annular rail; the laser tracking instrument moves through the annular rail; the four target seats are used as global control sites in the transfer station process. The device has the advantages that when the measuring conditions are insufficient, a measuring method with easy operation and high efficiency is provided; all practical measuring points are fitted into a sphere by SA software; a deformation region is analyzed trough the deviation value of the practical measuring points and the fitted sphere; the deviation value of points on the deformation region is compared with the respective fitting maximum deviation value for analyzing the deformation quantity of the corresponding deformation region.

Description

technical field [0001] The invention relates to the technical field of heat treatment deformation detection, in particular to a heat treatment deformation measurement device for large spherical structural parts. Background technique [0002] The laser tracker measuring system is a high-precision large-scale measuring instrument in the measuring system in the industry. It integrates various advanced technologies such as laser interference ranging technology, photoelectric detection technology, confidential mechanical technology, computer control technology, modern numerical calculation theory, etc., to track space moving targets and measure the three-dimensional coordinates of the target in real time, mainly with large-scale equipment Precise measurement of geometric shapes and key dimensions in manufacturing is mainly based, but due to the complexity of its own structure, operator technology, measurement methods and external environment all have an impact on measurement accu...
