[0002] In the current machining field, the demand for machining multiple lifting lug part numbers is increasing. Each lifting lug part number typically requires a specially designed fixture to ensure machining accuracy and efficiency. However, this one-to-one fixture configuration has led to a series of problems in actual production.
[0003] Specifically, when multiple lifting lug part numbers need to be processed simultaneously, the existing processing flow requires operators to disassemble the currently used fixture after processing one lifting lug part number, and then install a fixture suitable for the next lifting lug part number. This process is not only cumbersome and time-consuming, but the frequent disassembly and installation of fixtures can also lead to wear and tear on the fixtures themselves, thus affecting their positioning accuracy and service life. In addition, frequent fixture changes increase the labor intensity of operators and reduce overall production efficiency. Utility Model Content
