The concrete measuring process of above-mentioned measurement mechanism:
(1) preparatory stage:
Back out screw 43,41, take off upper supporting plate 12, turn left and right handwheel is retracted between the push pedal of left and right left and right push pedal 23,19 and can puts down arm, grating sensor slide block 17,6 is slided to right-hand member, guarantees to measure feeler lever 20,2 and does not exceed right push pedal 18 left sides;
(2) install fixing to be measured joint be installed:
the inner ring 36 of the installation joint that will measure is enclosed within the c section of interior backup rolls 21, the conical surface that the following and interior backup rolls of joint inner ring is installed contacts, the clamping element conical surface is enclosed within the b section of interior backup rolls down, make the conical surface of clamping element and the joint inner ring is installed and contact, with the circle hole sleeve at upper supporting plate center on the external cylindrical surface of clamping element, two ends decide 42 with the register pin of lower carrier plate respectively, 44 installations that match, load onto the packing ring nut of screwing in backup rolls a section and compress clamping element downwards, and then fixed installation joint inner ring, rotate right hand wheel 9, precession leading screw 10, and then advance right push pedal 18, the wall of right push pedal and arm is contacted, make zero to the pressure display unit of right pressure transducer this moment,
(3) exert pressure and measure:
be rotated further right hand wheel 9, leading screw continues to advance, Compress Spring 14, pressure display unit numerical value rises, the power that push pedal is applied on 19 of arms constantly increases, make joint Internal and external cycle 35 is installed, 36 pressure on interior backup rolls right side constantly increase, the value of Internal and external cycle pressure equals the displayed value of pressure display unit, right hand wheel stops operating when pressure display unit shows the force value of Chinese Civil Aviation Maintenance handbook regulation, install this moment and save the force value that just there is a regulation contact position, Internal and external cycle right side, this moment is with grating sensor slide block 17, 6 release to the right, make the bulb of planar survey feeler lever 20 and the external cylindrical surface of clamp 22 contact and lean on magnetic-adsorption, make the bulb of lower planar survey feeler lever 2 and the e section Cylindrical Surfaces Contact of interior backup rolls 21 also lean on magnetic-adsorption, the registration of two grating scale displacement displays is made zero,
rotate left hand wheel 29, the left leading screw 28 of precession, left push pedal 23 is contacted with arm 19 walls, this moment, the pressure display unit registration with right pressure transducer 24 made zero, be rotated further the left hand wheel, precession leading screw Compress Spring 26, pressure between left push pedal 23 and arm 19 walls constantly increases, the trend that arm is promoted is to the right arranged, rotation with the left hand wheel, pressure between left push pedal and arm wall constantly increases, joint Internal and external cycle 35 is installed, the pressure on 36 contact position, the right constantly reduces, and then be zero, the pressure of 18 pairs of arms of pressure and right push pedal of 23 pairs of arms 19 of left push pedal this moment is identical, it is all setting, with continuing to increase of pressure, the contact of joint Internal and external cycle on the left side is installed, and pressure constantly increases, joint Internal and external cycle 35 is installed, the pressure that pressure between 36 equals 23 pairs of arms 19 of left push pedal deducts the pressure of 18 pairs of arms 19 of right push pedal, the left hand wheel stops operating when the pressure display unit of left pressure transducer shows 2 times of settings, because the deformation quantity of right side spring does not have to change substantially, so pressure or the setting of right push pedal to arm, the pressure of joint Internal and external cycle in the contact position, left side is installed is left push pedal this moment the pressure of arm is deducted right push pedal to the pressure of arm, it is just in time namely the setting in the Chinese Civil Aviation Maintenance handbook, and the contact position when there is no pressure with left push pedal is relative, joint inner ring 36 is installed in this process to be moved to the left a section with respect to outer ring 35 and to have moved, this displacement is exactly the gap between the installation joint Internal and external cycle that will measure, when inner ring moves with respect to the outer ring, measurement feeler lever 2 due to magnetic absorption on corresponding cylinder, 20 also have the displacement of corresponding size, and drive grating sensor slide block 6, 17 at grating scale 7, the displacement of one section corresponding size has been arranged on 15, thereby the displacement that shows on the displacement display that grating scale is corresponding at this moment is exactly the gap between the installation joint Internal and external cycle that will measure,
Because the possible pulling force difference of lower carrier plate in the process of exerting pressure may make interior backup rolls not parallel with respect to the right push pedal that grating scale is installed, can rotate with the centre of sphere that joint inner ring sphere is installed, make the displacement of top grating scale large/less than the displacement of following grating scale, two grating scales are installed, and the mean value of getting these two grating scales can reduce the measuring error that causes due to above-mentioned situation;
(4) read measurement numerical value:
The mean value of getting two grating scale readings is the gap between the installation joint Internal and external cycle that will measure.Measure and slide block of sensor is return to the right after complete, rotate handwheel unloading applied pressure, unload clamp, take off upper supporting plate, take off the engine arm, deposit after the parts of corresponding measurement mechanism are installed.
The above is only preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvement, these improvement also should be considered as protection domain of the present utility model.
