Technical Field

The invention relates to a middle position quick adjusting device suitable for laser displacement detection of a field crystallization vibrator.

Background

At present, acceleration and speed sensors are often adopted for detecting the movement of mechanical equipment at home and abroad, but the theory involved in evaluating the movement condition of the equipment based on the detection of the acceleration and speed sensors is complex, and some application occasions are far less convenient, intuitive and direct than the method adopting displacement detection to reflect the movement running condition of the equipment. Previously, methods for evaluating the state of equipment based on displacement detection were limited due to the technical limitations of sensors that detect displacement. The laser displacement sensor is based on the laser principle, belongs to the non-contact detection of the motion of a detected surface, and has the characteristics of good dynamic characteristic, high precision and the like. When the laser displacement sensor is applied to field detection at present, the defects of no difficulty in median adjustment, long adjustment time and the like exist, and the application of the laser displacement sensor to the field detection is limited because the laser displacement sensor cannot meet the requirement of quick field adjustment. The existing device is complex in general mechanism, cannot be adjusted quickly, and is not strong in working condition adaptation capability.
