[0002] In the manufacturing process of shaft parts, the dimensions of shaft parts need to be inspected and measured to ensure that the shaft parts entering the next process or leaving the factory are qualified products. The existing product dimensions are mostly measured using vernier calipers. This measurement method is relatively inefficient, and personnel will become fatigued after measuring for a long time, which affects the judgment of the measurement results; the uniformity of the results measured by each person for the same product is relatively low, and the measurement techniques are also different. Especially for the position of the journal, the inspection results on both sides of the same plane may be different due to errors in the same inspection, which seriously affects the inspection and judgment of the product, and has high workload and operation requirements for the inspectors, low measurement efficiency, and low measurement accuracy, which cannot meet the requirements of mass production.
