Principle of work of the present utility model:
Eight cylinders of the present utility model link to each other with the PLC control system by solenoid directional control valve respectively, control system of the present utility model is a prior art, as shown in Figure 4, earlier measured differential mechanism workpiece is placed, this moment, measuring head 36 was in the differential mechanism inside cavity, do not have interference with each part of differential mechanism, press the measurement start button then; Five, six cylinders 9,10 work, the output shaft withdrawal, clamp paw 34 along with the withdrawal of the 5th, six cylinder output shafts until with the differential mechanism clamping and positioning.First and second cylinder 5,6 work, output shaft stretches out, and drive installation has first and second sliding support 20,30 of first and third slide block 19,29 to move to the differential mechanism direction on first and third guide rail 18,28 respectively.Be installed in first sliding support 20, first axle sleeve 21, the 3rd cylinder 7, splined shaft 25 and servomotor 13 on first slide block 19 jointly along with first slide block 19 moves; Be installed in second sliding support 30, second axle sleeve 31, four-cylinder 8 and driven shaft 35 on the 3rd slide block 29 jointly along with the 3rd slide block 29 moves.Servomotor 13 is also started working when moving along with first slide block 19, drive 15 rotations of first belt pulley by reductor 14, first belt pulley 15 drives second belt pulley, 16 rotations that are connected with splined shaft 25 by belt 17, and then the splined shaft 25 that drives this side rotates, promptly the splined shaft 25 of this side is along with move to the differential mechanism direction on first slide block, 19 limits, under the driving of servomotor 13, rotate again, and 35 of the driven shafts of opposite side are along with the 3rd slide block 29 moves to the differential mechanism direction.When the output shaft of first and second cylinder 5,6 drive first and second sliding support 20,30 stretch out put in place after, the 3rd cylinder 7 is started working, the output shaft withdrawal of the 3rd cylinder 7, first end cap 22 that is connected with output shaft is along with output shaft is withdrawn; Because first axle sleeve 21 and first end cap 22 are affixed, second end cap 23 and first axle sleeve 21 that are set on the splined shaft 25 are affixed, therefore, first axle sleeve 21, second end cap 23 and splined shaft 25 are also along with first end cap 22 moves, and this moment, splined shaft 25 put in axle shaft gear 2 splines of differential mechanism; After treating that splined shaft 25 puts in place, servomotor quits work after rotating for 2 seconds again.When the 3rd cylinder 7 was started working, four-cylinder 8 was also started working, and the output shaft of four-cylinder 8 stretches out, and the 3rd end cap 32 that is connected with output shaft is along with output shaft stretches out; Because second axle sleeve 31 and the 3rd end cap 32 are affixed, the 4th end cap 33 and second axle sleeve 31 that are set on the driven shaft 35 are affixed, therefore, second axle sleeve 31, the 4th end cap 33 and driven shaft 35 be also along with the 3rd end cap 32 moves, and this moment, the driven shaft 35 of this side put in the right axle shaft gear 3 that compresses differential mechanism in the housing of differential mechanism.Then, the 7th, eight cylinders 11,12 of differential mechanism below are started working, output shaft drives two measuring heads 36 that second slide block 27 is installed respectively and moves on second guide rail 26, and measuring head 36 moves laterally respectively and compresses left and right half gear 2,3 in the differential mechanism inside cavity; After treating that two measuring heads 36 put in place, two linear displacement transducers, 24 numerations of the left and right sides are zero-bit h1L, h1R this moment.After linear displacement transducer 24 numerations, the 7th, eight cylinders 11,12 reverse operations, measuring head 36 is regained; Simultaneously, third and fourth cylinder 7,8 is also distinguished reverse operation, and splined shaft 25 and driven shaft 35 are by extracting out in the differential side gear, and the left and right half gear 2,3 in the differential mechanism is no longer compacted.Delay time after 1 second, the 7th, eight cylinders 11,12 forward work once more, make measuring head 36 compress a left side once more, right axle shaft gear 2,3, two linear displacement transducers 24 h2L that counts once more, h2R, because this moment the 3rd, four- cylinder 7,8 have extracted splined shaft 25 and driven shaft 35 out, a butt left side no longer, right axle shaft gear 2,3, so poor (h2L-h1L) of twice counter value, (h2R-h1R) be the differential side gear gap length, control system is selected the pad of respective thickness for use according to measured gap width size, and comes prompting operation person by the pilot lamp on the respective pads film magazine is bright.
The utility model can be fit to high-level automobile gearbox assembling line or differential mechanism professional production producer uses.
