Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of plate fixing clamps, and particularly relates to a quick fixing clamp. BACKGROUND

[0002] In the production and manufacturing of metal plates, the metal plates need to be cooperated between multiple stations to reach the required specifications. In the transportation of the plates between the multiple stations, clamps are mostly used to fix the plates for convenient transportation. In order to avoid leaving marks on the surface of the plates during the transportation process and affecting subsequent processing, suction cup clamps are used to fix the plates and transport the plates.

[0003] The existing suction cup clamps fix the plates by removing or vacuumizing the air in the cavity between the suction cup and the plate, so that the suction cup is adsorbed on the surface of the plate under the action of atmospheric pressure, and the plate is pulled to move when the suction cup is lifted.

[0004] However, in the early stage of processing the metal plates, the surface of the metal plates is usually an irregular rough plane, and the part of the suction cup in contact with the surface of the plate is prone to have a gap. The gap causes the internal cavity of the suction cup to be connected to the outside, so that the suction cup cannot be adsorbed on the surface of the plate, resulting in fixing failure. In the later stage of processing the metal plates, the surface of the plate is processed to set grooves or arrange protrusions according to the actual use of the plate. During the placing process of the suction cup, the suction cup actively avoids the positions provided with other structures. However, the unavoidable problem is that the edge of the suction cup contacts the positions provided with grooves or protrusions. The suction cup in contact with the position provided with the grooves causes the internal cavity of the suction cup to be connected to the outside, so that the suction cup cannot be adsorbed on the surface of the plate, resulting in fixing failure.
