Abstract

The invention provides a processing method and system for casting reference. The method comprises steps that S1, a reference coordinate system is constructed for pre-whirl nozzles, and reference coordinate system information is acquired; S2, overall dimension information is acquired; S3, dimension detection fitting result information is acquired; S4, position information of a positioning pin is acquired according to the dimension detection fitting result information; S5, the positioning pin is welded to a designated position according to the position information of the positioning pin; S6, a top surface of the positioning pin is processed, an end surface is obtained by processing, a reference plane is determined, and information of the reference plane is obtained; S7, reference construction result information is acquired; and S8, processing result information of the casting reference is acquired according to the reference construction result information. According to the processing method and system for the casting reference, consistent reference of manufacturing, checking and machining of the casting is realized in a true sense.

Description

technical field [0001] The invention relates to the field of casting processing, in particular to a method and system for processing a casting reference. Background technique [0002] Except for a small number of castings that can be directly used without machining, most of them require subsequent machining due to dimensional accuracy, installation and surface roughness, etc., to meet the technical requirements of part design. The casting process of complex castings is difficult, the casting cycle is long, and the casting precision is poor. For castings with small machining surface margins, it is difficult to use trial cutting to detect. In order to meet the requirements of performance and production progress, the determination of casting processing benchmarks is particularly critical, which determines the dimensional accuracy of the final processed product. If the processing benchmark is not selected properly, the processed product will be out of tolerance, the dimensional...
