Abstract
The invention relates to a pneumatic positioning clamping mechanism for an aircraft assembly tool. The pneumatic positioning clamping mechanism is composed of a pneumatic positioning device and a pneumatic chuck. A pneumatic motor is arranged on a positioning pin shaft base in the pneumatic positioning device. A threaded rod is arranged on one side of the pneumatic motor. A coupling is arranged between the pneumatic motor and the threaded rod. A nut base is arranged on the outer circumference of one side of the threaded rod. A positioning pin is arranged on one side of the nut base. A positioning post sleeve is arranged on the outer circumference of the positioning pin. A pneumatic travel switch is arranged on the positioning pin. Under the circumstance that the precision and reliability of an aircraft assembly tool framework are not influenced, reconfiguration of the aircraft assembly tool framework can be achieved, matching with components of new models is achieved through the reconfigurability of the tool framework, the large aircraft assembly tool framework is repeatedly used, and therefore the manufacturing cost of aircrafts is reduced, the development and production preparation cycle of aircrafts is substantially shortened, and the rapid development of new models of aircrafts is accelerated.
