Description
Technical field
The present invention relates to a kind of coaxality measuring mechanism, specifically a kind of front and back cylinder center hole coaxality measurement dress
It sets.
Background technology
Automobile air conditioner compressor is the heart of automobile air conditioning refrigerating system, plays compression and conveys the work of refrigerant vapour
With.And the processing quality of wherein front and back cylinder center hole directly affects assembly and the performance of entire compressor.Therefore preceding
Rear-bank rotor housing needs to be detected two centre bore concentricities after processing is completed.Tradition is carried out to it by three coordinate arrangements
It measures, there are three defects, first, equipment acquisition cost is high, and second, it is not only more demanding to the operational capacity of staff,
And it is higher to operating environment requirements, it can only be confined to laboratory, can not adapt to detect on the line of mass production, the
Three, that there is only labor intensity when measurement is big, time of measuring is long, ineffective disadvantage, and generally can only probably measure one
A circle, while can have tilt phenomenon when placing product to be measured, influence measurement accuracy.
Then my company has developed a kind of coaxality measuring mechanism, including workbench, chassis, positioning column, balancing spring, fixed
Cylinder body when measurement, directly can be passed through bearing by position axle sleeve, positioning core axle, cylinder assembly, differential measurement device and ring standard gauge
Hole is set on positioning core axle, and the front-bank rotor housing reference plane of cylinder body is made fully to be fitted on the upper surface on chassis, then by chassis two
Pressure head on the cylinder assembly of side navigates to above the rear-bank rotor housing of cylinder body, while air source is connected on ball valve, opens ball valve, cylinder
Work, pressure head is pushed down to the rear-bank rotor housing of cylinder body, be now placed in front-bank rotor housing one end bearing hole be positioned accurately at positioning shaft sleeve with
On positioning core axle, the differential measurement device being placed on ring standard gauge finally plug behind school zero bearing hole of rear-bank rotor housing
In, while being sleeved on positioning core axle, after confirming set in place, the gauge stand one for rotating amesdial encloses, and reads maximum value and minimum value
Difference is the error that cylinder body double end bearing colludes axis degree.But find in use for some time, there is also two aspects to lack
It falls into：On the one hand, it is detected using longitudinal due to detection mode, the center line of front and back cylinder center hole is perpendicular with horizontal plane, leads to
It crosses setting cylinder to carry out longitudinal register to front and back cylinder body, easily causes front and back block distortion, influence front and back block quality；Another party
Face, since there are gap, when measurement easily makes amesdial rotate, locating effect between the amesdial and positioning core axle of setting
Difference, there are measurement errors, reduce measuring accuracy.
