Measure device.
Background technology
Often clearance gauge or depthometer etc. is used to check axial gap when aircraft axial gap measures at present.Clearance gauge or depthometer
It checks that precision is not high, for gap in components interior, cannot be checked well, especially when axial gap is by attachment
Internal spring force, when the influences such as thrust bearing assembly, it is difficult to measure to bring prodigious difficulty, conventional method to axial gap measurement
Precise gap value.
Utility model content
The purpose of this utility model is to check check for end play precision using clearance gauge or depthometer etc. for the prior art
Not high, for gap in components interior, the deficiency that cannot be checked well proposes a kind of aircraft attachment axial gap
Measuring device；It is characterized in that, the pedestal 1 of the aircraft attachment axial gap measuring device is fixed on workbench face, axis
It is п shape holders to clearance measurement tooling 12, is fixed on pedestal 1, DOCK LEVELER 2 is fixed on pedestal 1, attachment fixed seat 5
It is on п shape rack plates to be coaxially fixed on axial gap to measure tooling 12 with DOCK LEVELER 2；The upper and lower surface of pressure meter 3
Pull rod is coaxially connected with center-pole 4, DOCK LEVELER 2 respectively, for measuring axial push-pull power；5 top of attachment fixed seat is arranged
Clip 6, for fixed tested attachment shell；First limiter 7, the second limiter 8 are used and are threaded on center-pole 4, in
Core bar 4 is fixed with tested aircraft accessory internal dish axle, and amesdial 9 is fixed on axial gap by amesdial fixed seat 10 and measures
Tooling 12 is on п shape rack plates；The contact pilotage of amesdial 9 is contacted with 4 top middle portion of center-pole.
First limiter 7 is located at below tested attachment, the second limiter 8 is located at tested aircraft accessory, uses
In fixed tested aircraft accessory internal dish axle, prevent from moving radially.
The measurement range of the pressure is 0-110 (lb).
The measurement range of the amesdial is 0-1mm.
The utility model has the beneficial effects that the measurement to aircraft attachment axial gap, is eliminated by pressure in attachment
Portion influences the gap of axially measured exact value, measures the dish axle upper limit and lower limit difference by amesdial, degree of regulation is high, is easy to adjust
Section realizes that rapid, operation is simple；The present invention disclosure satisfy that the type axial gap measurement request, the scope of application are wider.
Description of the drawings
Fig. 1 is that axial gap measures tool structure schematic diagram.
Specific implementation mode
The utility model proposes a kind of aircraft attachment axial gap measuring devices, are explained below in conjunction with the accompanying drawings.
Fig. 1 is that axial gap measures tool structure schematic diagram.The pedestal 1 of the aircraft attachment axial gap measuring device is solid
It is scheduled on workbench face, it is п shape holders that axial gap, which measures tooling 12, is fixed on pedestal 1, DOCK LEVELER 2 is fixed on
On pedestal 1, it is on п shape rack plates that attachment fixed seat 5 is coaxially fixed on axial gap to measure tooling 12 with DOCK LEVELER 2；
The upper and lower surface pull rod of pressure meter 3 is coaxially connected with center-pole 4, DOCK LEVELER 2 respectively, for measuring axial push-pull power；
The measurement range of pressure is 0-110 (lb)；Clip 6 is arranged in 5 top of attachment fixed seat, for fixed tested attachment shell；The
One limiter 7, the second limiter 8 are using being threaded on center-pole 4, and the first limiter 7 is below tested attachment, second
Limiter 8 is located at tested aircraft accessory, for fixed tested aircraft accessory internal dish axle, prevents from moving radially.In
Core bar 4 is fixed with tested aircraft accessory internal dish axle, and amesdial 9 is fixed on axial gap by amesdial fixed seat 10 and measures
Tooling 12 is on п shape rack plates；The contact pilotage of amesdial 9 is contacted with 4 top middle portion of center-pole, is used for measuring center bar axial direction position
Shifting degree determines tested aircraft attachment axial direction gap width.The measurement range of the amesdial is 0-1mm.
The step of measurement axial gap principle of the aircraft attachment axial gap measuring device, is as follows：
1) before tested aircraft attachment is mounted on axial gap measuring device, first first adjusts 7 height of limiter, makes
It is concordant with attachment fixed seat 5 to obtain the first limiter 7；
2) tested aircraft attachment is installed on center-pole 4, unclamps clip 6, rotation DOCK LEVELER 2 adjusts center-pole
4 axial height, the tested aircraft attachment jacked up are fallen so that and tested aircraft attachment is axially aligned with tested tooling,
It prevents from measuring and deviation occurs, and with tight clip 6；
3) the second limiter 8 is installed on center-pole 2, fixes tested aircraft attachment dish axle；By touching for amesdial 9
Needle is contacted with 4 top middle portion of center-pole, proceeds by measurement；
4) when measuring, DOCK LEVELER 2 is adjusted first so that center-pole 4 is moved downward to pressure meter 3 and shows that regulation is drawn
Force value pushes down on tested aircraft attachment dish axle by the second limiter 8, is tested aircraft attachment dish axle to eliminate and is tested
Tested aircraft attachment dish axle lower bearing gap, reads 9 registration A of amesdial；
5) adjusting DOCK LEVELER 2 again makes center-pole 4 be moved upward to pressure meter 3 and show regulation thrust magnitude, makes
It obtains the first limiter 7 and is tested aircraft attachment dish axle and bearing clearance above tested aircraft attachment dish axle, read at this time
Amesdial registration B, ︱ A-B ︱ values are then attachment precise gap value.
