Comprehensive Error Calibration Device and Method for Cylinder Grinding Busbar Gauge of Carding Machine

Abstract

The invention discloses a carding machine cylinder grinding needle bus size adjusting tool integration error verification apparatus. A pedestal is provided with a detection panel through a leveling device. Two ends of the detection panel are provided with a left groove and a right groove respectively. Center lines of the left groove and the right groove are provided with positioning screw holes respectively. A center line between the two grooves is provided with a bar-type groove. Upper portions of the left groove and the right groove are provided with a left end positioning component and a right end positioning component respectively. Upper portions of the left end positioning component and the right end positioning component are provided with a detection mandrel A and a detection mandrel B respectively. A middle end positioning component is also included. The middle end positioning component comprises a positioning component A, a positioning component B, a positioning rod and a positioning spring. The bar-type groove is provided with a mobile holding block. The left end positioning component and the right end positioning component are fixed to upper portions of the left groove and the right groove through positioning bolts. In the invention, roundness, parallelism and a fixed value error of a size adjusting tool can be verified so that precision of a kind of special-purpose testing fixture is guaranteed to satisfy a production requirement.

Description

technical field [0001] The invention relates to a checking device for a special checking tool in the textile industry, in particular to a checking device and method for a comprehensive error checking of a carding machine cylinder grinding needle busbar. Background technique [0002] In the textile industry, the carding machine cylinder grinding needle busbar gauge is a special inspection tool for equipment flat cars. This inspection tool is mainly used for positioning the front and rear positions of the needle grinding machine shaft and the cylinder cylinder busbar during the carding machine flat car Inspection to ensure the operation quality of the equipment after the flat car. [0003] Such as Figure 6 , Figure 7 It can be seen that the carding machine cylinder grinding needle bus bar gauge 9 includes a semi-cylindrical body 91 and a detection square 92, the semi-circular groove 910 is arranged along the axis on the semi-cylindrical body 91, and its detection square 92 ...

AI Technical Summary

Problems solved by technology

After this kind of checking tool is bought back from the manufacturer, due to the frequent use of flat cars, the semicircular groove 910 and the square port 921 are worn out, the parallelism between the two, the fixed value of the distance and the roundness of the semi-cylindrical surface The error 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.
