Abstract

The invention provides a laser displacement sensor vibration compensation platform, including a laser measuring device, a signal processor and a compensation calculation device; the laser measuring device includes a laser displacement sensor, an acceleration sensor, an angular velocity sensor and a fixture; the signal processor includes a data an acquisition card and a signal amplifier; the data acquisition card is used to acquire the output voltages of the laser displacement sensor, the acceleration sensor and the angular velocity sensor; The output voltages of the laser displacement sensor, the acceleration sensor and the angular velocity sensor are calculated to obtain displacement, vibration displacement error and vibration angle error, which are substituted into the shape-position correction matrix to obtain the position and displacement of the measurement point of the laser displacement sensor after compensation. The invention solves the problem that the existing laser displacement sensor is easily affected by vibration to measure the accuracy of the measured part.

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...
