Problems solved by technology

The arrangement of circular reflectors is time-consuming, laborious and inefficient
The lack of a circular reflector often affects detection
The above reasons restrict and limit the wide application of CCD visual three-coordinate measuring instrument in vehicle body detection, and there is no practical and convenient device to solve the above problems

Abstract

The invention relates to a reference device for detecting railway freight car and an arrangement method thereof. The reference device comprises a base, vertical columns, triangular rib plates, triangular steel plates, triangular blocks and circular reflectors. The vertical columns are vertically welded to the central position of the base, the triangular rib plates are welded between the base and the two sides of the vertical column, the tops of the vertical columns are of inclined face structures, the triangular steel plates are welded to inclined faces, and the triangular steel plates are welded to the inclined faces. The triangular blocks are welded to the positions, close to the triangular steel plates, of the upper portions of the vertical columns, the triangular blocks are welded to the two lateral faces of the vertical columns respectively, and the triangular blocks are arranged in a staggered mode. Cylindrical grooves with smooth bottoms are formed in the triangular blocks and the triangular steel plates respectively, cylindrical grooves are also formed in the vertical columns above the triangular blocks, and the circular reflectors are adhered to the bottoms of the cylindrical grooves. The reference device for detecting the railway freight car is combined and arranged according to the length of a tested car body and can meet the requirement for detecting the railway freight cars of different specifications.

Description

technical field [0001] The invention relates to a reference device and an arrangement method thereof, in particular to a reference device for railway freight car detection and an arrangement method thereof. Background technique [0002] After the railway freight car body is manufactured, it is necessary to test its key assembly and matching dimensions to ensure the subsequent assembly quality. One of the detection methods is to use a CCD (Charge-coupled Device, charge-coupled device sensor) visual three-coordinate measuring instrument to detect its related space matching dimensions to determine the quality of these dimensions. Before testing, the CCD visual three-coordinate measuring instrument needs to set (paste or place magnetic) multiple circular reflectors on the detected car body. After scanning all the circular reflectors, the CCD visual three-coordinate measuring instrument calculates The spatial position of each circular reflector is taken as the datum reference po...
