Description

Technical Field

[0001] The present application relates to the field of flange adjustment inspection, and in particular, to an auxiliary tooling for inspecting the end face runout and stop runout of a reducer input flange. Background Art

[0002] During the machining process, various flanges are often involved. In situations where flange machining accuracy is relatively high, especially when the accuracy of the flange's outer surface is relatively high, the tolerance of the flange's outer circumference is often strictly limited. For example, various form and position tolerances must be limited to a relatively small range. Currently, the difficulty in testing such flanges lies in the detection of the runout tolerance within the position tolerance. Generally, the runout tolerance value cannot be directly measured and read using general measuring tools, which is also a problem encountered in testing the runout tolerance.

[0003] The common detection means is to use the three-coordinate method to perform detection or use dedicated electronic equipment to perform measurement, but the cost of using the three-coordinate method and dedicated electronic equipment is relatively high, and the inspection process is auxiliary.
