[0002] Composite casting refers to casting two or more metal materials with different properties into a complete casting, so that different parts of the casting have different properties to meet the requirements of use. Usually, one alloy has higher mechanical properties, while the other or several alloys have special performance such as wear resistance, corrosion resistance, and heat resistance.

[0003] Patent application number 201721175888.8 is a composite reference positioning fixture for precision castings. By setting a first positioning pin, the first positioning pin moves radially with the slider. When positioning the casting reference, the second and third positioning pins are first used for positioning, and then the position of the slider is adjusted so that the first positioning pin radially supports the part outward, and then the clamping screw is tightened to fix the first positioning pin. The above case does not have the function of adjusting the reference positioning block. Due to the different shapes of composite castings, the fixture cannot clamp different composite castings. In addition, the existing composite casting reference positioning fixture requires a long time to find the position accuracy and adjust, and the composite casting cannot be quickly replaced, which reduces work efficiency.
