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

At the same time, the existing electrical connection between components is often realized by the abutment matching between the connecting rod and the connecting contact. Although this arrangement can realize the electrical connection of the components to a certain extent, the above-mentioned arrangement form The stability of the conduction form is poor, and the conduction effect is often affected by the movement and vibration of the components; moreover, for the conduction components set on the machine tool, it is often difficult to obtain effective protection in the non-working state, especially in the When the machine tool performs processing operations, it is often necessary to spray various processing fluids on the workpiece, which causes the risk of short circuit or damage to the conductive parts on the machine tool, resulting in electrical short circuit damage to the equipment or a short service life of the conductive structure

[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.
