Description

Technical Field

[0001] The utility model belongs to the technical field of shaft parts processing, and in particular relates to a shaft parts quality detection device. Background Art

[0002] In the machining manufacturing industry, lathes are often used to make some shaft parts. Shaft parts are key components in mechanical devices for supporting and transmitting power. They are usually used to connect various rotating parts and transmit torque. Common shaft parts usually include smooth shafts, stepped shafts, and special-shaped shafts.

[0003] Nowadays, when lathes are used to process stepped shafts, the coaxiality requirements for the stepped shafts are relatively high. Coaxiality refers to the degree to which the axes of two cylindrical surfaces are in the same straight line. It can be used to control the coaxiality error between the measured axis and the reference axis of shaft parts. In order to check whether the coaxiality of the stepped shaft meets the requirements, it is often necessary to conduct a coaxiality quality test on the stepped shaft after processing.

[0004] Nowadays, when testing the coaxiality of stepped shafts, quality inspectors often clamp the shaft parts between two tips, then place the inspection contacts of the dial indicator against the side wall of the shaft, and then manually turn the shaft to make it rotate. During the rotation of the shaft, by observing the changes in the numbers or pointers on the dial indicator, it can be determined whether the coaxiality error of the shaft is within the designed range. However, measuring the coaxiality error of the shaft by manually turning the shaft to rotate will invisibly increase the workload of quality inspectors, and the efficiency of quality inspection is not high.
