Description

Technical Field

[0001] The invention relates to the technical field of spline shaft detection, and in particular to a detection device for a spline shaft after manufacturing and forming. Background Art

[0002] The spline shaft is a type of mechanical transmission. Like the flat key, semicircular key and wedge key, the spline shaft transmits mechanical torque. There is a longitudinal keyway on the surface of the shaft, and the rotating parts on the shaft also have corresponding keyways to keep rotating synchronously with the shaft. After the spline shaft is manufactured, it needs to be tested for dimensional parameters such as roundness and length to ensure that its quality and performance meet the design requirements.

[0003] When operating the current spline shaft detection device, it is usually necessary to fasten the spline shaft to a specific fixture. This practice limits the free rotation of the spline shaft during the detection process, which may hinder the accurate measurement of the roundness of the spline shaft and affect the detection efficiency and accuracy. In addition, the fixture design used in the existing detection device is often inflexible and not convenient for adjusting the clamping position of the spline shaft. This limitation may cause certain key areas of the spline shaft to be blocked by the fixture and cannot be effectively detected, thereby weakening the comprehensiveness and reliability of the detection.
