Description

Technical Field

[0001] The utility model relates to the technical field of testing machine displacement measurement, in particular to a high-precision testing machine displacement measurement device. Background Art

[0002] Testing machine displacement measurement devices are commonly used to detect parameters such as the flatness and curvature of a workpiece surface. A laser beam is emitted by a laser, and a receiver receives the reflected laser signal. The distance to the surface point of the object being measured is calculated by measuring the time delay or phase change of the laser signal. This device can perform continuous or discrete measurements at multiple points to obtain distance data for multiple points. The device can quickly scan multiple points on the workpiece surface, record the distance data for each point, and select multiple points to analyze the flatness or planarity of the workpiece. For example, flatness is usually evaluated based on the distance difference between each point on the surface to assess the flatness of the surface, while flatness considers the deviation of the distance between each point and a certain reference plane.

[0003] In the prior art, there is a problem of inaccurate detection results caused by the laser line deviating from the horizontal direction. When the laser deviates from the horizontal direction, the measured distance may deviate from the actual distance. This deviation will increase with the increase of the deviation angle, resulting in a decrease in the accuracy of the measurement results. If the laser line is not evenly distributed on the plane or has a significant angular offset, the measurement results at different points may be different, resulting in inconsistent measurement results in different areas. In response to the above problems, the inventors proposed a high-precision testing machine displacement measurement device to solve the above problems. Utility Model Content
