Description

technical field [0001] The invention belongs to the technical field of workpiece detection, and in particular relates to a laser-based on-machine measuring device and a measuring method. Background technique [0002] During the processing of the workpiece, it is often necessary to measure the processing size of the workpiece to judge whether the processing accuracy of the workpiece is qualified and ensure the accuracy of the workpiece preparation. [0003] Under normal circumstances, for the detection of workpieces, it is often necessary to remove the workpiece from the processing position after all parts of the workpiece are processed, and then clamp and detect the workpiece in the detection device. This detection method requires secondary clamping of the workpiece. The process is cumbersome; moreover, the above-mentioned detection methods cannot detect the processing parts of the workpiece at any time. Once there is a problem with the processing accuracy of a certain part,...

Problems solved by technology

[0003] Under normal circumstances, for the detection of workpieces, it is often necessary to remove the workpiece from the processing position after all parts of the workpiece are processed, and then clamp and detect the workpiece in the detection device. This detection method requires secondary clamping of the workpiece. The process is cumbersome; moreover, the above detection methods cannot detect the processing parts of the workpiece at any time. Once there is a problem with the processing accuracy of a certain part, the processing accuracy of other parts will also be affected correspondingly, which makes the workpiece have a greater risk of being scrapped

[0004] In addition, at present, most of the detection methods for workpieces are contact detection methods. For workpieces with regular structures, this detection method can realize the detection function to a certain extent, but for workpieces with irregular structures (such as curved surface workpieces, For deep hole workpieces), the detection accuracy is often low, the control is cumbersome, the efficiency is low, and it is easy to be limited by the structure of the workpiece. It is necessary to fully consider the length of the measuring rod of the workpiece probe, and the structural design of the measuring tool is limited.

Moreover, the contact measurement method often requires special planning of its measurement path, which puts forward high technical requirements for the operator, which is not conducive to the actual promotion and application, and has certain application limitations.
