Abstract

The invention provides detection equipment and a detection system for a machined workpiece. The device comprises: a base comprising a body and a conductive structure located in the body; the detection structure comprises a main body part and a measuring head, and the main body part comprises a shell, a liquid storage part, a movable part, a power supply and a wire. In the equipment, the conductive structure can be used as a part of a circuit, in the moving process of the movable part, the circuit is switched on at the moment when the measuring head makes contact with a machined workpiece to form a loop, the measuring head in the scheme does not need to swing by a certain angle or move by a certain distance, the sensitivity is high, and then the measuring precision is high, so the problem that in the prior art, the sensitivity of a measuring head for detecting errors of a machined workpiece is relatively low is solved; and in the scheme, when magnetorheological fluid is in a solid state, the movable part cannot move up and down any more, and then the problems that in the prior art, inertia force and oscillation are too large during sudden stop after a measurement task is completed can be avoided, so the working efficiency of measurement is improved.

Description

technical field [0001] The present application relates to the field of numerical control machine tools, in particular, to a detection device and a detection system for processing workpieces. Background technique [0002] Due to factors such as thermal deformation and cutting vibration of CNC machine tools, there are certain errors between the actual parameters of the processed workpiece and the theoretical parameters. Accurately measuring the error of the workpiece processed by the machine tool is of great significance for evaluating the processing performance of the machine tool. At present, the machining accuracy of CNC machine tools has reached the micron level. To accurately measure the dimensional error of the workpiece requires extremely high-precision testing equipment. [0003] At present, the commonly used error measurement tool is a trigger three-coordinate measuring machine. The coordinate position of each measuring point is obtained by touching the surface of the...
