Description

Technical Field

[0001] The utility model relates to the technical field of fixing tooling, and more specifically to a vacuum suction cup fixing tooling for aluminum alloy thin plates. Background Art

[0002] Aluminum alloy thin plates are a commonly used material in the manufacturing industry. During the logistics and transportation of aluminum alloy thin plates, they are often stacked in multiple layers. When transporting them to the processing station for taking a single aluminum alloy thin plate, a vacuum suction cup is often used to adsorb the thin plate and lift it to the processing station. When installing, the vacuum suction cup needs to be installed on the surface of a fixed tooling.

[0003] After searching, the existing patent (publication number: CN208880242U) discloses a communication cabinet monitoring device. When in use, thin plate parts are placed on the upper surface of the placement part, and the plate body is fixed on the vacuum suction cup. The vacuum suction cup is connected to the second exhaust hole, and the thin plate parts are adsorbed on the upper surface of the placement part through the exhaust channel and the first exhaust hole. The setting of the sealing groove improves the sealing between the thin plate parts and the upper surface of the placement part. The clamping of parts is convenient and quick, and there is no need for repeated adjustment, thereby reducing workload and improving work efficiency. Not only can the parallelism of the parts be guaranteed, but also the flatness of the parts can be guaranteed. However, in the process of realizing the present invention, the inventor discovered that the prior art had the following problems: the above-mentioned fixing tool is a large plane as a whole, and thus after the vacuum suction cup is installed, the vacuum suction cup is also in an overall plane structure, and it has excellent effects when used for flat aluminum alloy sheets, but when used for aluminum alloy sheets with folded edges, the folded edge portion of the aluminum alloy sheet will appear suspended due to lack of fixation. In this case, the folded edge portion will pull the flat portion of the aluminum alloy sheet downward under the action of gravity and cause deformation of the bending area, affecting the subsequent normal use of the aluminum alloy sheet. In view of this, the present invention proposes a vacuum suction cup fixing tool that can be used for aluminum alloy sheets with folded edges. Utility Model Content
