Description

Technical Field

[0001] The utility model relates to the technical field of step difference detection tools, in particular to a precision structure step difference detection tool. Background Art

[0002] The step difference detection is a quality inspection method that measures the thickness difference or height difference of the product being tested, and compares the measurement result with the range of allowable deviation of the thickness or height of the product to determine whether the product is qualified. Among precision structural parts, shaft parts are commonly used parts. The working capacity and working quality of the machine are largely related to the shaft. Once the shaft fails, it may cause serious consequences. Therefore, the structural dimensions of shaft precision structural parts must be within a reasonable range. Therefore, in the production process of shaft precision structural parts, it is often necessary to conduct random inspections and perform step difference detection on the shaft. However, most of the existing step difference detection equipment is medium and large-scale equipment, and the shaft needs to be transported to the corresponding equipment for detection.
