When axle 321 rotates, power can be acted to bearing installation axle 321, so that bearing installation axle 321 can produce becoming of moving left and right
Gesture.In the event of movement, then the rotation of swivel bearing 324 can be influenceed, and then influence the adjustment of distance and angle.Therefore, will be even
Base of the fishplate bar 31 as bearing installation axle 321, the movement for preventing bearing installation axle 321 from occurring when by external force, Jin Erke
Avoid influenceing the Adjustment precision of swivel bearing 324.Bearing installation axle 321 is fitting to connection with swivel bearing 324, swivel bearing 324
The periphery of bearing installation axle 321 is set in, the central shaft for making bearing installation axle 321 be rotated as swivel bearing 324；Swivel bearing
324 are fixed in bearing fixed block 325 by bearing installation axle 321, can only be in bearing fixed block to limit swivel bearing 324
Central area rotation in 325, and then improve Adjustment precision.
In another optional embodiment, with being in place of the difference of a upper embodiment, swivel assemblies
32 also include bearing stop collar 322 and bearing installation axle fixed block 323；Bearing installation axle fixed block 323 can be limited further
The movement of bearing installation axle 321, and when bearing installation axle 321 is embedding with swivel bearing 324 by bearing installation axle fixed block 323
During conjunction, increase the frictional force between bearing installation axle 321 and bearing installation axle fixed block 323 using stop collar 322, to prevent
The movement of bearing installation axle 321, and then avoid influenceing the Adjustment precision of swivel bearing 324.
Specifically, stop collar 322 is set in bearing installation axle 321；Bearing installation axle fixed block 323 is set in rotation
On bearing 324；Bearing installation axle 321 is chimeric with swivel bearing 324 by bearing installation axle fixed block 323 and stop collar 322
Connection.
It can be seen that limiting the movement of swivel bearing 324 by bearing fixed block 325, and pass through bearing installation axle fixed block
323 and connecting plate 31 bearing installation axle 321 is clamped, and between increase stop collar 322 to improve frictional force, with limit
Dead axle holds the movement of installation axle 321.Therefore, when swivel bearing 324 rotates along bearing installation axle 321, running accuracy can be improved,
And then it can accurately adjust the distance between two quick union components 2 and angle so that pneumatic joint is provided with air inlet
Keeping parallelism between face and the inner surface 231 of fixed seat 23, and then the stability of air pressure in air supply pipe 22 is improved, and air-flow stream
Enter the efficiency of article carrying platform, avoid the occurrence of the situation of air pressure shakiness or flow leakage, cause article carrying platform not detect exactly
Defect.
Shifting sledge 34 is fastened on slide rail firm banking 36；Slide rail firm banking 36 is used to provide surely for shifting sledge 34
Fixed support force, prevent shifting sledge 34 from the skew of position itself occur, influence the precision of its intense adjustment.
And in order to which shifting sledge 34 can be made effectively to be fixed, it is respectively symmetrically solid at the both ends of slide rail firm banking 36
A fixed slide rail fixed block 35, makes the both sides of shifting sledge 34 be fixed on slide rail fixed block 35.In order to avoid influenceing shifting sledge 34
Slip, it is desirable to slide rail fixed block 35 is parallel to each other with slide rail firm banking 36, formed concave structure.In order to alleviate shifting sledge
34 when sliding to impacting caused by slide rail fixed block 35, the upper end of slide rail fixed block 35 is passed through elastic mechanism 33 and rotary shaft
The bottom resilient connection of bearing assembly 32.
