Description

technical field [0001] The invention relates to the field of workpiece machining equipment, in particular to a multi-station automatic clamp. Background technique [0002] With the rapid development of the modern aviation industry and the acceleration of my country's modernization process, the aviation industry is developing rapidly under modern high-tech conditions, and the automation and flexibility of process equipment has always been a problem that the aviation industry needs to solve. At present, the flexibility and automation of aircraft structural fixtures are low. Manual clamping methods are still used for workpiece clamping, which is time-consuming and labor-intensive. The fixture assembly time and workpiece clamping time are much longer than the workpiece cutting time. Lead to low production efficiency, low machining accuracy and high cost. The multi-station flexible automatic tooling system can not only reduce tooling manufacturing costs, quickly and accurately r...
