Abstract

The invention discloses an attachment performance detection device for electrified contact surfaces of shaft parts. The device comprises two clamping assemblies used for clamping a shaft part and a detection assembly arranged on the clamping assemblies and used for making contact with the end face of the shaft part, and the shaft part is located between the two clamping assemblies. According to the attachment performance detection device for the electrified contact surfaces of the shaft parts, effective detection of the attachment performance of the electrified contact surface of the shaft part can be realized, and the sparking phenomenon during flaw detection operation on the shaft part is avoided.

Description

technical field [0001] The invention belongs to the technical field of shaft parts detection, and in particular, the invention relates to a device for detecting the bonding performance of energized contact surfaces of shaft parts. Background technique [0002] Shaft parts are widely used in various motion and transmission systems. In modern industry, many high-speed, high-precision and high-demand machinery need to be inspected for shaft parts. Magnetic particle inspection is used in the inspection of surface and near-surface defects. The detection effect is very good. When detecting circumferential defects and cracks, it is necessary to pass a large current to the shaft itself, and the electrode is clamped and contacted when electrifying. In this process, if there is no good contact between the shaft end and the electrode, an arc discharge phenomenon (commonly known as ignition) will occur when a large current is passed, which will burn the shaft surface of the ignition par...
