Abstract

The invention discloses a hydraulic drive and double-working-tape compounded aero-engine rotor and stator clamping device, which belongs to the technical field of precise clamping. The device is characterized in that a sealing cavity is surrounded by an inner sleeve, a middle sleeve, an outer sleeve, an extension pipe, a connecting piece, a pressure detector, a pressurizer, a bottom plate, a sealing nozzle and a piston; hydraulic oil is injected through an oil injection hole and is pressurized in the cavity by the pressurizer; pressure is transmitted to an upper-layer annular oil duct, a middle-layer annular oil duct and a lower-layer annular duct via a communication path; the piston is pushed to drive an upper-layer annular working tape and a lower-layer annular working tape to synchronously retract to clamp a tested piece, and clamping force is monitored in real time and precisely controlled. The invention establishes the precise clamping device which combines high precision and high stability.

Description

technical field [0001] The invention belongs to the technical field of precision clamping, in particular to an aeroengine rotor-stator clamping device combined with hydraulic drive and double working belts. Background technique [0002] As the advanced equipment manufacturing industry gradually develops towards precision and ultra-precision, especially the continuous improvement of the performance level of aero-engines, the requirements for the precision of engine processing, assembly and measurement are getting higher and higher, especially in the pursuit of higher thrust-to-weight ratio. Due to the engine vibration, noise and other factors caused by assembly and measurement errors, the impact on engine performance is becoming more and more significant. In particular, the clamping accuracy of aero-engine rotor-stator components in assembly and measurement has a great impact on engine assembly and manufacturing. Higher requirements are put forward for the clamping device use...
