Abstract

The invention discloses a wear image acquisition system and an acquisition method. In the wear image acquisition system, a loading mechanism is configured to apply a preset load value to a to-be-tested sample through a friction piece; a one-dimensional horizontal movement displacement table comprises a friction base body for keeping a sample to be measured; the one-dimensional horizontal movementdisplacement table is driven by a motor to reciprocate; a motor control module is connected with the motor; the motor control module sends a control command to actuate the motor, so that the to-be-tested sample and the friction piece rub for a preset number of times at a preset speed at a preset load value; the grinding mark image acquisition module faces the to-be-detected sample, the grinding mark image acquisition module is used for shooting and storing a grinding mark image at preset time intervals, the friction force acquisition module is used for acquiring a corresponding friction forcesignal while shooting the grinding mark image, and the grinding mark feature recognition module is connected with the grinding mark image acquisition module to recognize the grinding mark image so asto extract a grinding mark feature; and the grinding mark image processing module generates a label based on the grinding mark image, calibrates a corresponding friction force signal and stores the friction force signal.

Description

technical field [0001] The invention relates to the technical field of wear measurement, in particular to a wear image acquisition system and acquisition method. Background technique [0002] Equipment wear is a common phenomenon in mechanical equipment, and it is also a key factor that restricts the life of mechanical equipment and operating costs. At present, the most effective way to reduce equipment wear is to monitor the wear state and replace the worn parts before they fail. Reduce the damage caused by its sudden failure to the machine. At present, the commonly used wear detection methods mainly include vibration monitoring technology, oil analysis, infrared thermal imaging, and endoscopic detection methods, etc., but these methods cannot accurately and quickly reflect the wear status of the contact surface, and the development of image acquisition technology is difficult. It provides a brand-new means for wear monitoring, which can more intuitively and effectively in...
