According to the difference in processing methods, it can be divided into cutting processing and pressure processing. The existing patent is a processing reference conversion tool for curved surface parts, patent announcement number CN203156619U, which includes a base plate, a positioning pin and a fastening nut. The base plate has a positioning hole, the positioning pin cooperates with the positioning hole, and the fastening nut is connected to the positioning pin to fix the curved surface part. The utility model solves the technical problems that the curved surface parts are difficult to position, difficult to clamp, and difficult to perform corresponding reference conversion in multiple processing procedures. The positioning pin of the utility model constrains the reference hole on the curved surface part and the corresponding positioning hole on the base plate. The fastening nut can fix the curved surface part on the base plate, solving the clamping problem of the curved surface part. Due to the regular shape of the base plate, the position processing accuracy can reach a high level, so through the high-precision position requirements of the base plate, the high processing reference accuracy of the curved surface parts is guaranteed.
