Title:
DEVICE AND METHOD FOR DETECTING SPATIAL POSITIONING PRECISION OF NUMERICAL CONTROL MACHINE TOOL
Document Type and Number:
WIPO Patent Application WO/2023/039943
Kind Code:
A1
Abstract:
Disclosed in the present application are a device and method for detecting spatial positioning precision of a numerical control machine tool. The numerical control machine tool comprises two opposite machine tool columns. The device comprises positioning rings, line ruler boxes, and a detection mechanism. N positioning rings are arranged on opposite surfaces of the two machine tool columns, and a three-dimensional space is enclosed between all the positioning rings, wherein N is a natural number greater than or equal to 2, the number of the line ruler boxes is equal to the number of the positioning rings, the line ruler boxes are respectively arranged at positions, close to the corresponding positioning rings, on the machine tool column, and a self-recovery measuring line of each line ruler box movably passes through the positioning ring at the corresponding position, and the line end of the self-recovery measuring line of each line ruler box is connected to a connector. The detection mechanism is located between the two machine tool columns, one end of the detection mechanism is connected to a machine tool spindle, and the other end of the detection mechanism is connected to each connector. The present application has the advantages of wide detection range, high efficiency and low cost.
