The auto pump shaft connecting bearing radial internal clearance measuring apparatus, operation principle are as follows：
Before formal measurement, auto pump shaft connecting bearing to be measured is transmitted to feed inlet 2 from a upper station by conveyer belt, waits for
Constraint of the bearing by feed inlet is surveyed, 2 bottom of feed inlet is rolled into, when the first photoelectric sensor 3 has detected bearing arrival, feeding
Motor 8 is started to work, and feed wheel 10 is driven to rotate 60 degree.The bearing claw of feed wheel 10 triggers bearing core shaft to be measured and carries out feeding.
After feed wheel 10 rotates through 120 degree, the tip contact of bearing to be measured and raceway 5 at this time, and take advantage of a situation and rolled down along raceway, it is rolled into
Behind 5 bottom end of raceway, it is parked on the V-groove of 5 bottom end of raceway.First photoelectric sensor has detected that bearing arrival, the second load carry
Lotus oil cylinder 13 pushes the second bearing fixed block 14 to be measured to move, the second bearing fixed block 14 to be measured then slowly contact measured bearing,
It is lifted off raceway, keeps bearing axis to be measured and the first compression axis 16,23 center line of the second compression axis substantially conllinear.Due to water
The mandrel for pumping shaft connecting bearing is asymmetrical design, to just passing through the detection of the second photoelectric sensor before radial internal clearance measuring mechanism
To the length of both ends mandrel, according to program setting, the first compressed oil cylinder 17, the second compressed oil cylinder 24 pass through different speed respectively
The first cylinder 16 and the second cylinder 25 is pushed to move, to drive the first compression axis 16 and the second compression axis 23 and axis to be measured respectively
It holds two end in contact of mandrel and compresses, the first compression axis 16, the second compression axis 23 and mandrel contact surface are taper hole, and there is pressure on taper hole surface
Force snesor, when pressure sensor numerical value reaches setting value, the first compressed oil cylinder 17 and the second compressed oil cylinder 24 stop pushing.
Two control mobile motors 26 rotate at this time, and band moving gear 28 rotates, and to drive sensor support base 27 to move, drive the respectively
One displacement sensor 18, second displacement sensor 22 move, and contact bearing outer ring both ends.First displacement sensor 18, second
When the displacement that displacement sensor 22 is fed back reaches program preset range, then stop continuing to move to.First load simultaneously
Load oil cylinder 21 drives the first bearing fixed block 19 to be measured to move, and is contacted with bearing outer ring to be measured.
When formal measurement, process 1：The power that first loaded load oil cylinder 21 is pre-designed according to program is first to be measured to push
Bearing fixed block 19 moves, the first bearing fixed block 19 to be measured and bearing outer ring continuous contact to be measured, the second loaded load oil cylinder
13 power being pre-designed according to program pull the second bearing fixed block 14 to be measured to move, at this time the first displacement sensor 18, the
Two displacement sensors 22, which measure numerical value, constantly to be changed.When the first displacement sensor 18 and second displacement sensor 22 are continuous multigroup
When data are substantially unchanged, according to advance program setting, the first loaded load oil cylinder 21, the stopping of the second loaded load oil cylinder 13 are applied
Power, the change in displacement difference of the first displacement sensor of program meeting automatic storage 18 and second displacement sensor 22.Following second
The power that loaded load oil cylinder 13 is pre-designed according to program pushes the second bearing fixed block 14 to be measured to move, the first loaded load
The power that oil cylinder 21 is pre-designed according to program pulls the first bearing fixed block 19 to be measured to move, at this time the first displacement sensor
18, second displacement sensor 22 measures numerical value and can constantly change.When the first displacement sensor 18, second displacement sensor 22 is continuous
When multi-group data is substantially unchanged, according to advance program setting, the first loaded load oil cylinder 21, the second loaded load oil cylinder 13 stop
Only exert a force, change in displacement difference (1 knot of process of the first displacement sensor of program meeting automatic storage 18 and second displacement sensor 22
Beam).Continue repetitive process 1 twice.After the completion of repetitive process 1, process 2 is carried out：The load of first loaded load oil cylinder 21, second carries

It is dynamic, sensor control mechanism control respectively the first displacement sensor 18, second displacement sensor 22 by program it is preset away from
From mobile to disengage bearing outer ring to be measured.Two control electric rotating machines drive the first compression axis 16 and the second compression axis respectively
23 rotations 120 degree (end of process 2).Sensor control mechanism controls dynamic first displacement sensor 18, second displacement sensing respectively
Device 22 is mobile with contact measured bearing outer ring by the preset distance of program.When the first displacement sensor 18, second displacement passes
When the displacement that sensor 22 is fed back reaches program preset range, then sensor control mechanism stops mobile first displacement and passes
Sensor 18 and second displacement sensor 22.Repetitive process 1 is three times.After the completion of this process, understands repetitive process 2 again, then weigh
Multiple process 1 is three times.Program can carry out the change in displacement difference that the first displacement sensor 18 and second displacement sensor 22 store
Averaging handle, finally judge the average value measured by the first displacement sensor 18 and second displacement sensor 22 error whether
It is presetting in range.If so, 22 measured values of the first displacement sensor 18 and second displacement sensor are obtained average value again
It is averaging output；If it is not, carrying out manual inspection after then being remeasured or discharged.
After being measured, power that the first loaded load oil cylinder 21 is pre-designed according to program pulls the first bearing to be measured solid
