Description
Technical field
The utility model relates to Piston Machining field, particularly relates to a kind of piston annular groove and pin-and-hole concentricity and surveys
Amount device.
Background technology
Piston is the important component part of engine, and Piston Machining quality directly has influence on service life of aeroengine or service property (quality), in Piston Machining, piston snap ring or pin-and-hole are for placing piston annular groove and bearing pin, and being rapid wears, annular groove and bearing pin easily grind part, therefore ensureing the concentricity of piston snap ring and pin-and-hole, is the important step that ensures snap ring scouring machine bearing pin installation quality.
At present, piston annular groove and pin-and-hole are in process, general adopt roundness measuring equipment detecting instrument to or piston annular groove and pin-and-hole carry out the side leakage of concentricity, it is long that but roundness measuring equipment detects life period, the shortcomings such as work efficiency is low, and degree of detection is poor, have had a strong impact on product process-cycle and quality, cause shopwork efficiency low, poor product quality.
Utility model content
The technical matters that the utility model mainly solves is to provide a kind of piston annular groove and pin-and-hole concentricity measuring device, can increase work efficiency, and reduces human cost and drops into, and accuracy of detection error is reduced to minimum simultaneously, effectively improves product percent of pass.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of piston annular groove and pin-and-hole concentricity measuring device are provided, comprise: support, axle, dial gauge, special indicator and dial gauge locating rack, described support comprises base plate and location-plate, described location-plate is vertically set on base plate top, described axle is horizontally installed on location-plate, described dial gauge is arranged on dial gauge locating rack, described special indicator is arranged on dial gauge, and described dial gauge locating support and base plate be arranged in parallel.
In preferred embodiment of the utility model, on described location-plate, be provided with pilot hole.
In preferred embodiment of the utility model, the tolerance of described pilot hole and axle is+0.001mm.
In preferred embodiment of the utility model, it is characterized in that, described axle one end is provided with screw thread.
The beneficial effects of the utility model are: a kind of piston annular groove of the utility model and pin-and-hole concentricity measuring device, can increase work efficiency, and reduce human cost and drop into, accuracy of detection error is reduced to minimum simultaneously, effectively improve product percent of pass.
