[0002] The robotic arm is an important part of an industrial robot. To ensure that it has a high structural strength, the robotic arm is usually cast. Industrial robots usually include multiple types of robotic arms, and the same robot may have robotic arms of different specifications and sizes. Since the robotic arms of industrial robots are relatively long, some are about 2 meters long. Figure 1 A first manipulator sand core having a length of about 1.6 meters is shown, as shown in the attached Figure 2 A second robot arm sand core with a length of about 1.8 meters is shown. The two sand cores are of different lengths but similar in structure. At present, the two sand cores are generally configured with jigs for placing the sand cores, which results in a large amount of jig warehouse space being occupied. When switching products on the casting production line, the corresponding jig needs to be replaced, and line change takes a long time. Utility Model Content
