Abstract
The invention discloses a synchronous self-locking pneumatic adaptive fixture used for the machining of annular thin-walled parts, belonging to the technical field of mechanical machining. The synchronous self-locking pneumatic adaptive fixture includes a zero point positioning system, a base body, a plurality of pressure plate mechanism assemblies, a plurality of columns, a plurality of support mechanism assemblies and a plurality of adaptive support body assemblies. Among them, the pressure plate mechanism assemblies complete the axial compression of the workpiece through the lever force increasing mechanisms and the orthogonal self-locking mechanisms. And the support mechanism assemblies complete the radial support of the workpiece through the rod slider mechanisms and the orthogonal self-locking mechanisms. The invention not only has high clamping efficiency and good stability, but also can ensure the reliable clamping and safe machining of the workpiece when the air source is disconnected.
