Description

[0003] The flaw detection device is used to detect whether the parts are qualified after the production of automobile parts is completed. Only the parts batch that passes the sampling inspection can be put into use. The flaw detection device is a device for detecting whether the surface of the parts has cracks. Its principle includes ultrasonic flaw detection, magnetic powder flaw detection, etc. Taking magnetic powder flaw detection as an example, the part needs to be clamped between the conductive blocks. After the conductive blocks are electrified, the magnetic field generated by the conductive blocks penetrates the inside of the part. Then the liquid containing magnetic substances and developing fluid is sprayed on the surface of the part. The tiny cracks on the surface of the part will cause the magnetic field to be disturbed, so that the magnetic substances drive the developing fluid to gather on the surface of the part. The tiny cracks on the surface of the part can be found by shining a flashlight.

However, the existing flaw detection device cannot rotate the parts, and can only rely on the detection personnel to manually disassemble the parts, adjust the direction and reposition them into the conductive blocks, resulting in low efficiency.
