Abstract

The invention provides a vibration compensation platform of a laser displacement sensor. The vibration compensation platform comprises a laser measurement device, a signal processor and a compensationcalculation device; the laser measurement device comprises a laser displacement sensor, an acceleration sensor, an angular velocity sensor and a fixture; the signal processor comprises a data collection card and a signal amplifier; the data collection card is used for collecting output voltages of the laser displacement sensor, the acceleration sensor and the angular velocity sensor; and the compensation calculation device respectively calculates a displacement, a vibration displacement error and a vibration angle error according to the output voltages of the laser displacement sensor, the acceleration sensor and the angular velocity sensor collected by the data collection card, and substitutes the displacement, the vibration displacement error and the vibration angle error into a shape and position correction matrix to obtain a compensated measurement point position and displacement of the laser displacement sensor. The vibration compensation platform provided by the invention solves the problem that the existing laser displacement sensor is vulnerable to vibration to affect the measurement accuracy of a measured component.

Description

technical field [0001] The present invention relates to the technical field of laser displacement sensors, in particular to a vibration compensation platform for laser displacement sensors. Background technique [0002] Laser displacement sensor is the core component of non-contact measurement. Laser displacement sensor has the advantages of high measurement efficiency and simple operation. Accuracy directly affects the measurement accuracy of the final measured part. [0003] At present, the most widely used laser displacement sensor does not have a vibration compensation device. The measurement error caused by the vibration of the laser displacement sensor during measurement will reduce the accuracy of the measured part, making the measured part not meet expectations, increasing processing costs, and low operating efficiency. . Contents of the invention [0004] According to the technical problem that the existing laser displacement sensor is easily affected by vibrati...
