the rubber gasket 5 is fixed on the interlayer backing plate 4 through a rotating shaft, and the rubber gasket 5 can freely rotate around the shaft. The circular rubber lamination can keep the clamped object to rotate along with the movement, and prevent the clamped object and accessories thereof from scattering due to inversion
An air cylinder structure 6 is arranged between the two clamping arms, and the air cylinder drives the two clamping arms to perform clamping action; specifically, the two ends of the cylinder structure 6 are respectively fixed on the first bolts, and the cylinder structure is located in the middle of the whole clamping arm structure. The air cylinder device is adopted, so that the load is large, the action is rapid, and the working environment adaptability is good.

The diameter of the clamping position of the object to be clamped is larger than the distance between the two rubber gaskets after the cylinder is completely executed, and under the action of static load, static friction force is generated between the two rubber gaskets and the object to be clamped so as to clamp the object.
After clamping is completed, the two driving motors 91 are started in cooperation, the whole object to be clamped is moved up under the action of the torsional supporting plate 9, and the object to be clamped is placed to a specified position through rotation of the motors to realize clamping.
Just because the existence of two rubber gaskets (and the rubber gasket can be around axle free rotation) for this device has apparent advantage when pressing from both sides and getting the object in the recess, under the combined action of gravity and notch, the thing takes place the rotation of continuous small range by the clamp when realizing pressing from both sides and getting, thereby has avoided the interference that probably takes place with the recess. The clamping device has certain stability when being clamped, can still maintain stability when being subjected to force vertical to the clamping device, and is reliable and durable.
