Abstract

The invention relates to the technical field of measuring a complex three-dimensional space curved surface with a three-coordinate measuring machine, in particular to a method for measuring the three-dimensional space curved surface of a radio-frequency quadrupole-field electrode pole head by the aid of three coordinates. The method includes: establishing a three-dimensional mathematical model for an RFQ (radio frequency quadrupole) electrode, and guiding the mathematical model into measuring software to compile a measuring program; placing the RFQ electrode into a three-coordinate measuring machine, and centering the same first manually and then by the aid of the program; compiling the measuring program; measuring an RFQ electrode pole head curve with a scanning probe and the peak of the electrode pole head; measuring electrode pole head surface points by the aid of a vector method. By the aid of the three-coordinate measuring machine, measuring of the complex three-dimensional space surface can be completed with high measuring precision and measuring efficiency, and machining detection level of the RFQ electrode pole head is greatly improved; machining precision of products is guaranteed, working efficiency is improved, and machining error can be reflected visually.

Description

technical field [0001] The invention relates to the technical field of measuring complex three-dimensional curved surfaces by three-coordinate measuring machines, in particular to a method for measuring three-dimensional curved surfaces of radio frequency quadrupole field electrodes using three-coordinates. Background technique [0002] The manufacturing level of radio frequency quadrupole field (RFQ) electrodes is one of the key factors affecting the performance parameters of RFQ cavity. The pole head carries high radio frequency voltage, and its stability and reliability are very important to the RFQ cavity. Therefore, whether the processing quality of the RFQ electrode head can be guaranteed through good measurement technology depends on the quality factor of the RFQ cavity and the stability of the resonance frequency. . At present, when using conventional measurement methods, since the RFQ electrode head is a three-dimensional space surface, it is difficult to achieve m...
