Abstract

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. It establishes a three-dimensional space mathematical model for the RFQ electrode, and imports the mathematical model into the measurement software to compile a measurement program. Put the RFQ electrode on the three-coordinate measuring machine, first manually align it, then use the program to align it, compile the measurement program, use the scanning probe to measure the RFQ electrode tip curve, measure the highest point of the tip curve, and use the vector point method to measure the pole. Head surface point. It uses a three-coordinate measuring machine, which not only can complete the measurement of complex three-dimensional space surfaces, but also has high measurement accuracy and fast measurement efficiency, which greatly improves the processing and detection level of RFQ electrode heads. It ensures the processing accuracy of products, improves work efficiency, and intuitively reflects processing errors.

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...
