Description

Technical Field

[0001] The utility model relates to the field of transmission shaft processing and detection, and particularly relates to a device for measuring the slope length of a transmission shaft. Background Art

[0002] As an important mechanical component, the transmission shaft is widely used in engineering machinery fields such as automobiles. The transmission shaft is responsible for transmitting the power of the engine to the wheels, etc., and is an indispensable part of the entire mechanical system. The transmission shaft needs to be connected to a universal joint assembly (including inner and outer wheels, cage, etc.) to play its role. In some cases, the assembly position of the transmission shaft and the universal joint assembly is at the virtual diameter position of the transmission shaft slope. Therefore, the accuracy of the corresponding length of the virtual diameter has a crucial impact on the assembly quality. To accurately measure this dimension, generally, a profilometer is used for measurement. However, on the one hand, as a precision instrument, the profilometer is expensive and has certain requirements for the instrument placement location, and it is not easy to be directly used at the production site. On the other hand, the principle of the profilometer is that the probe climbs out of the contour of the specified position of the workpiece to be measured, and then point capture is confirmed, which requires a certain amount of measurement time, is time-consuming, and has certain requirements for measurement skills.
