A three-dimensional scribing process for group holes of steel truss members

Abstract

The invention relates to a three-dimensional marking process for group holes of a steel truss bar. The process comprises the following steps: on a working platform of a three-dimensional marking machine, using a jack and a bar manufacturing center line to horizontally adjust the steel truss bar, and checking the coordinate system of a left marking measuring arm and a right marking measuring arm; then respectively operating the measuring arms to control handles according to a drawing size, moving on three coordinate directions of an X axis, a Y axis and a Z axis by utilizing the real-time numerical values of a three-axis digital displayer of the marking machine, and carrying out marking operation by utilizing marking needles at the end parts of the measuring arms. The process has the advantages that the process firstly introduces the three-dimensional marking machine to work in the marking line manufacturing work of the steel truss bar, adopts mechanized construction and utilizes high-precision three-dimensional marking machine to control the marking line precision, so that the marking line precision is high, and the degree of mechanization is high; the number of the needed operating persons is less; only one to two operating persons are needed, and the fast and efficient making can be realized.

Description

technical field [0001] The invention relates to a three-dimensional scribing process, in particular to a three-dimensional scribing process for group holes of steel truss members. Background technique [0002] During the fixed installation of steel truss rods, marking is required to ensure accurate installation and positioning. The traditional marking method is to adjust the level of the rods on a large special marking platform, using special steel squares, height gauges, and high-precision micrometers. Carry out manual scribing of steel truss member group holes. The scribing platform needs to process the plane as a whole to ensure the flatness and levelness, and mark the scale line on the platform plane; the scribing work requires more than 3 operators to carry out the scribing operation, which requires a lot of labor; the scribing work height Depending on the skill level of the marking team, the marking data needs to be calculated or converted by the marking operator.

The scribing platform needs to process the plane as a whole to ensure the flatness and levelness, and mark the scale line on the platform plane; the scribing work requires more than 3 operators to carry out the scribing operation, which requires a large amount of labor; the scribing work height Depending on the skill level of the marking team, the marking data needs to be calculated or converted by the marking operator. For steel truss beams with complex shapes, other auxiliary equipment such as laser levels are also required, which is complicated and inefficient.
