At every one stage impeller is made of the impeller disk and multiple blades.The quality of rotor balancing directly affects the vibration of engine complete machine, institute
The balance quality of rotor can be effectively improved with the raising of single-stage impeller disk balance quality, guarantee global vibration of engine and started
Machine performance meets the requirements.
The balance quality of engine compressor rotor single-stage impeller disk is assembled on balancing machine by balancing device (tooling)
It carries out amount of unbalance test to be adjusted, existing balancing device (tooling) is usually by serves 8, dividing bush 9, switching mandrel
7 and cover board 10 be bolted and be composed (see attached drawing 7).It since composition component is more, thus has the following problems: balance
There are biggish amount of unbalance, Equilibriums to be difficult to realize for device, this amount of unbalance measurement result for directly resulting in the impeller disk is missed
It is poor big, so that the balance qualification rate after making the later period be assembled into rotor is low；Because there are processing public affairs in the axis hole being tested on the impeller disk
Difference, to eliminate the fit-up gap between balancing device and tested impeller disk axis hole, it is necessary to process the other interval of multiple groups by tolerance
Bushing (machining tolerance of such as 0.08mm need to process eight groups of dividing bushes), not only increases the cost of manufacture of balancing device, and
Increase the workload that dividing bush is matched when assembling.
Summary of the invention
The purpose of the present invention is to overcome the deficiency in the prior art, provides that a kind of structure is simple, Equilibrium mouse with high accuracy
