Description

Technical Field

[0001] The present invention relates to the technical field of semi-axle processing, in particular to a detection device for semi-axle processing. Background Art

[0002] Axles, also known as drive shafts, are crucial components connecting the differential to the drive wheels. Their primary function is to transmit torque. During vehicle operation, engine power is transferred through the transmission reducer to the differential, which then transmits it to the drive wheels via the axles, propelling the vehicle forward or backward.

[0003] At present, during the processing of automobile half-axles, cracks may appear on the outer surface of the half-axle due to the influence of materials, manufacturing processes, design and other issues. Therefore, the half-axle must be inspected during processing to eliminate safety hazards. The existing method of inspecting the outer surface of the half-axle is generally that the staff first manually applies a penetrant liquid on the surface of the half-axle, then uses ultraviolet light to irradiate it to make it visible, and finally facilitates the staff to observe it with the naked eye. However, manually applying the penetrant liquid is not only time-consuming and labor-intensive, but also inefficient. It is also difficult for the penetrant liquid to completely penetrate into the crack gap. In particular, for small cracks, the penetrant liquid may be recovered before it penetrates, resulting in the crack not being visible under the irradiation of ultraviolet light. Therefore, it is easy to reduce the accuracy of the detection results. To this end, a detection device for half-axle processing is provided. Summary of the Invention
