The method of space takeover installation measurement

Abstract

The invention discloses a method for installation and measurement of a connecting pipe in space. The central axes of the two connecting pipes are on the same straight line. The method of the present invention aims at the measured object of the product, utilizes advanced detection equipment, optimizes and simplifies the installation and measurement procedures, performs real-time process control on the installation of the space connection, reduces the difficulty of measurement implementation, reduces the measurement cost, and reduces the measurement time and cost. Measuring personnel, to achieve the purpose of controlling the installation quality and improving efficiency.

Description

technical field [0001] The invention relates to a method for installation and measurement of space joints, which can guide and be applied to the installation and measurement of space joints, and belongs to the measurement and testing technology. Background technique [0002] On the gasifier product, there are four space connectors evenly distributed around the circumference of the cylinder at an equiangular angle (90°). The four connectors are the combustion nozzles of the gasifier, which are related to the normal operation of the entire product. Therefore, the installation and measurement of these connecting pipes have high technical requirements, such as: the central axes of the four connecting pipes are required to be on the same plane, the flatness is ≤0.5mm, the central axes of the two adjacent connecting pipes are perpendicular and intersect at one point, and the verticality is ≤ 1mm, the corresponding central axes of the two connecting pipes are on a straight line, an...

Problems solved by technology

[0003] In the past, in order to ensure the needs of installation and measurement work, or to make a large installation tool with the same inner diameter as the cylinder and a complex measurement tool, the entire installation and inspection process was very complicated and cumbersome, which was time-consuming and laborious.

Or place the spherical prism evenly on the cylinder, use the intelligent total station to measure and collect data one by one at the position of the spherical prism, combine the industrial measurement system, manually calculate and process the data, determine the center of the cylinder, and then place the cylinder Adjust the body and connecting pipes to a horizontal state, install the connecting pipes one by one and symmetrically on the top of the cylinder, and measure the cylinder and connecting pipes after installation, so process control cannot be carried out; the whole process takes a long time to install and the degree of automation is too low, which is harmful to the operator. The technical requirements are high. If the measurement data after the connection is installed and fixed is out of tolerance, the connection needs to be re-installed and measured, which not only delays the product manufacturing cycle, but also increases the manufacturing cost.

Or use the method of photogrammetry to take pictures of the measurement marks and coding marks on the cylinder and the connecting pipe, extract the coordinate points, and fit and calculate the positional relationship of the connecting pipe relative to the cylinder; but the measurement cost is high, and the arrangement of the measuring marks and coding marks It takes a long time to prepare, and the measurement marks and coding marks are easy to be worn due to the dense arrangement, which affects the measurement effect
