Composite error checking device for front roller parallelism ruler of textile roving frame and application method of composite error checking device

Abstract

The invention relates to a composite error checking device for a front roller parallelism ruler of a textile roving frame. An adjusting platform is arranged on a base, the top of the adjusting platform is provided with a groove, a fixing terrace is arranged on the left of the groove, a positioning terrace is arranged on the right of the groove, the fixing terrace comprises bottom plate A, one end of the bottom plate A is provided with magnetic L-shaped part A, and the bottom of the bottom plate A is provided with slider A; the positioning terrace comprises bottom plate B, the bottom of the bottom plate B is provided with a slider B, and a hollow square seat is arranged above the bottom plate B and is provided with an elongated open slot; a detection piece seat is arranged in the hollow square seat, the same side of the detection piece seat is provided with a V-shaped channel and a U-shaped part, a detection mandrel is arranged in the V-shaped channel, and the front ends of two sides of the U-shaped part are provided with horizontal detection end face A and horizontal detection end face B; a cover plate and a fine adjusting rotor are arranged above the hollow square seat, and a compression spring is arranged between the hollow square seat and the detection piece seat. The composite error checking device according to the invention has good checking accuracy and is convenient to use. The invention also discloses an application method of the composite error checking device.

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 for front roller parallel gauge of a textile roving frame and a use method thereof. Background technique [0002] In the textile industry, the front roller parallel gauge of the roving frame is a special inspection tool for equipment flat cars. This inspection tool is mainly used to correct the parallelism between the standard shaft and the front rollers during flat cars, so as to ensure the operation quality of equipment after flat cars. [0003] Such as Figure 8 It can be seen that the front roller parallel gauge 9 in the prior art includes the lower "<" groove 90 and the "┗" type part B91 provided on the upper part, and the two sides above the "┗" type part B91 are respectively provided with a working end surface A911, a working end surface B912. Under normal circumstances, the working end surfac...

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 the flat car, the working end face A911, the working end face B912 and the inner surface of the "<" groove 90 are worn, so that the contour plane between the working end face A911 and the working end face B912 and The fixed value error of the parallelism and spacing between the inscribed axis of the "<" groove 90 increases, which leads to a decrease in the detection accuracy of the gauge 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.
