Description

Technical Field

[0001] The utility model relates to the technical field of inspection tools, in particular to a diameter taper inspection tool for automobile differential housing. Background Art

[0002] Gauges are simple tools used by industrial manufacturers to control various dimensions of products (such as apertures, spatial dimensions, etc.) to improve production efficiency and control quality. They are suitable for mass-produced products, such as automotive parts, to replace professional measuring tools, such as smooth plug gauges, threaded plug gauges, outside diameter calipers, etc. Vernier calipers and depth gauges are measuring tools, not gauges. In a broad sense, special dimensional error detection tools that are adjustable and most parts can be reused can be classified as flexible gauges. The existing solution causes the differential housing to be placed directly on the test bench, where the differential housing cannot be effectively supported, which will affect the measurement results. The differential housing has many detection diameter positions and the measurement speed is slow, which cannot adapt to mass production in the workshop, and the measurement error is large when manual measurement is performed using vernier calipers and outside micrometers.

[0003] After searching, Chinese patent announcement number CN219223652U discloses a vehicle differential housing diameter measuring fixture. Through its convenient handheld detection structure design, that is, the overall fixture adopts an integrated structure design, and a gripping rod is provided, and a non-slip handle cover is fixedly sleeved on the gripping rod. When actually measuring the diameter of the automobile differential housing, the handheld fixture can be used to quickly complete the rapid measurement of the diameters of multiple automobile differential housings. Although the above patent solves the problem that the measurement speed is slow and cannot adapt to mass production in the workshop, it may be difficult to fit completely during use, and the fit is poor. It is necessary to add an adjustment device to ensure the fit and stability between them to a certain extent, so that the fixture can be more accurately adapted to the differential housing. In addition, displacement or shaking may occur during use, and a support device needs to be added to ensure the stability during the measurement process to a certain extent, and improve the reliability and repeatability of the measurement. Therefore, it is necessary to design a taper gauge for the diameter of the automobile differential housing. Utility Model Content
