Comprehensive error checking device and method for entering and exiting positioning gauge of tail vehicle surface of roving frame

Abstract

The invention discloses a comprehensive error checking device for entering and exiting a positioning gauge of a tail vehicle surface of a roving frame, which can check the verticality, the parallelismand the interval constant value error of a positioning gauge working surface. The device includes a base and an adjusting platform arranged on the base. A groove is arranged on the adjusting platform. The left end of the groove is provided with a positioning table A and the right end of the groove is provided with a positioning table B. Strip-shaped block A and strip-shaped block B are arranged above the positioning table A and B. An opening groove is arranged on the strip-shaped block A. An opening groove shaped like 'T' is arranged on the strip-shaped block B. A nematopore is arranged on the rear wall of the opening groove shaped like 'T'. An adjusting bolt is arranged in the nematopore. A detection piece is arranged in the opening groove shaped like 'T'. The detection piece comprises ablock shaped like 'T', a horizontal block and a piece shaped like 'T' which is arranged above the block shaped like 'T'. The front end of the horizontal block is provided with detection end surface A. The front end of the cross piece of the piece shaped like 'T' is provided with detection end surfaces B and C which are perpendicular to each other. The horizontal distance between the detection endsurface B and the detection end surface A is set as a constant value. The device has the advantages of accurate verification and convenient use.

Description

technical field [0001] The invention relates to a checking device for a special checking tool in the textile industry, in particular to a comprehensive error checking device and a using method of a roving machine tail car surface entry and exit positioning gauge. Background technique [0002] In the textile industry, the roving machine tail car surface entry and exit positioning gauge is a special inspection tool for equipment installation flat cars. This inspection tool is mainly used to correct and locate the position of the roller on the car surface frame to ensure the equipment operation quality after the flat car. . [0003] Such as Figure 7 It can be seen that the tail car surface entry and exit positioning gauge 9 in the prior art is composed of a vertical block 90 and a folding vertical block 91 arranged above it. The front end of the vertical block 90 is provided with a working surface A901, and the upper end of the folding vertical block 91 is provided with "┏" t...

AI Technical Summary

Problems solved by technology

After this type of inspection tool is bought back from the manufacturer, due to the frequent use of flat cars, the working surface B920 and the working surface C921 are worn out. The fixed value error of the degree and its spacing increases, which leads to a decrease in the detection accuracy of the positioning gauge 9 for the rear vehicle surface, and affects the quality of the equipment flat car

This kind of special inspection tools for textiles does not belong to the national conventional measuring instruments. At present, domestic professional testing institutions cannot test or calibrate this kind of inspection tools, and the accuracy of such special inspection tools cannot be tested in the existing technology of the industry.
