Along with the continuous lifting of aero engine technology, increasingly strict to the requirement of all technical of aircraft engine parts.
Certain oscillating bearing subassembly in aeromotor, is made up of oscillating bearing and ball joint head connecting rod.During assembling, use flaring die, under force, by the V-shaped groove enlarging in oscillating bearing both ends of the surface, the degree face, outside of V-shaped groove produces deformation, make together with oscillating bearing is coupled to each other with ball joint head connecting rod, make oscillating bearing and ball joint head connecting rod do not deviate to be considered as at the load lower bearing of equidirectional certain force qualified.
According to design drawing, to the requirement of oscillating bearing enlarging be, " enlarging place has not allowed crackle, and bearing rotates continuously, without clamping stagnation, kick ".Check whether oscillating bearing enlarging degree reaches requirement, and traditional method takes ocular estimate, i.e. the outward appearance of the binocular viewing enlarging of employment, compares with standard component simultaneously, judges that whether enlarging degree is qualified., by the impact of human factor, there is metrical error in this range estimation mode; And can there are differences unavoidably the detection of same oscillating bearing two sides enlarging degree, inconsistent.In addition, design drawing also requires that each batch of oscillating bearing subassembly to producing all carries out axial load detection, to ensure that each oscillating bearing subassembly all meets axial load requirement.And detect the axial load of oscillating bearing subassembly, and need be afterburning respectively to two of a bearing side, not only expend man-hour, and this reinforcing can have a strong impact on the serviceable life of Bearing assembly.
Utility model content
For above-mentioned prior art Problems existing, the purpose of this utility model is to provide a kind of measurer quantizing to detect for oscillating bearing enlarging degree, in order to alternative ocular estimate, realize detecting the quantification of oscillating bearing enlarging degree, eliminate testing result and be affected by human factors and the adverse effect of axial load detection to Bearing assembly serviceable life.
For achieving the above object, the measurer quantizing detection for oscillating bearing enlarging degree that the utility model provides, comprises base, central shaft, supporting sleeve, locating sleeve and movable sleeve; Described central axis is fixedly mounted on described base, and central shaft is divided into upper and lower two sections, and wherein epimere matches with the ball joint head endoporus of the ball joint head connecting rod of tested oscillating bearing subassembly, and hypomere matches with the endoporus of described supporting sleeve; The lower surface of supporting sleeve and the upper surface of base fit, and the upper surface of supporting sleeve and the lower surface of tested oscillating bearing fit; The endoporus of described locating sleeve is divided into upper and lower two sections, epimere endoporus matches with the epimere of central shaft, hypomere endoporus aperture is slightly larger than the diameter in tested oscillating bearing end face cross section crossing with the ball joint head of ball joint head connecting rod, the lower surface of locating sleeve and the interior degree end face (in V-type groove groove part) of tested oscillating bearing upper surface fit, and the cylindrical of locating sleeve matches with the endoporus of described movable sleeve; The lower end of movable sleeve becomes tilted conical, the flaring die consistent size of its degree face and oscillating bearing; There is a step upper surface of locating sleeve, and the height of step is the enlarging altitude range (L optimized
mAX-L
mIN), the height that the height of movable sleeve deducts locating sleeve equals enlarging minimum-depth optimal value (L
mIN).
Principle of work of the present utility model is:
In use procedure, central shaft epimere matches with the endoporus of tested oscillating bearing subassembly, fits in the lower surface of tested oscillating bearing and the upper surface of supporting sleeve, guarantees that surveyed oscillating bearing is ajusted automatically, ensures accuracy of detection; The lower surface of locating sleeve and the interior degree end face of measured bearing fit, and this position is not subject to enlarging, deformation does not occur, and it can be used as detection reference face reliable; The degree face of movable sleeve lower end and oscillating bearing flaring die consistent size, can simulate the actual effect of enlarging.
It is the enlarging altitude range optimized according to the height of locating sleeve upper surface step, the height that the height of movable sleeve deducts locating sleeve equals enlarging minimum-depth optimal value, the upper surface of movable sleeve and locating sleeve is touched with hand, the upper end level of perception movable sleeve and locating sleeve is poor, as long as the upper surface height of sensation movable sleeve is between the step of locating sleeve, can judge that Bearing assembly enlarging degree is qualified.
The beneficial effects of the utility model are:
1, structure is simple, easy and simple to handle, replaces traditional ocular estimate with it, and the quantification that can realize oscillating bearing enlarging degree detects.
2, detect oscillating bearing enlarging degree with this measurer, testing result can be avoided to be affected by human factors, and detection accuracy is high, can guarantee Detection job.
3, oscillating bearing enlarging degree is detected with this measurer, good owing to detecting consistance, when detecting the axial load of oscillating bearing, only need inspect one by random samples to same sets of batches component, and do not need all detecting, thus the adverse effect of this detection to Bearing assembly serviceable life can be avoided; The labour intensity of testing staff can be alleviated simultaneously, enhance productivity.
