Description

Technical Field

[0001] The utility model relates to the field of aerospace product processing, in particular to a vacuum suction cup specially used for processing aerospace wall panel products. Background Art

[0002] An existing patent (publication number: CN216359440U) proposes a dedicated suction cup for bottom plates. The cup comprises a suction cup base, a suction cup cover mounted on the base, and a boss formed on the cover. A vacuum chamber is formed on the upper surface of the cup base, and the lower surface of the cover is sealed to the periphery of the vacuum chamber. A vacuum connection seat is provided in the chamber, with vacuum holes provided in the seat. The boss has a dedicated suction groove for vacuum suction and fixation of the workpiece. The bottom of the dedicated suction groove has multiple suction holes distributed along the groove. The suction holes penetrate the boss and the cover and communicate with the vacuum chamber. However, the suction area of ​​the boss in this device is fixed and cannot be adjusted according to the actual size of the workpiece. This results in air leakage in uncovered areas of the workpiece, a disadvantage. Summary of the Invention

Beneficial effects

[0008] The suction cup cover of the utility model is fixedly connected to the suction cup base to form a vacuum chamber. When the connecting tube is connected to the vacuum pump through the vacuum tube and the vacuum chamber is evacuated to a vacuum negative pressure environment, the suction cup cover sucks and fixes the aerospace wall panel product workpiece through the suction cup hole, so as to carry out subsequent processing operations on the workpiece, prevent the workpiece from moving and offsetting during processing, causing processing errors, and improve the processing quality and operating efficiency of the aerospace wall panel products. A sealing strip is added at the connection between the suction cup cover and the suction cup base to improve the sealing of the connection between the suction cup cover and the suction cup base, reduce air leakage, and improve the fixing effect of the vacuum suction cup.

When the blocking plates on both sides move inward, the suction cup area is reduced, and when the blocking plates on both sides move outward, the suction cup area is increased. The structure is flexible, so that the adsorption area can be adjusted accordingly according to the actual size of the aerospace wall panel product workpiece, thereby preventing air leakage in the unblocked position of the workpiece and improving the fixing effect of the vacuum suction cup. Moreover, the suction cup area can be flexibly adjusted by turning the knob, which is easy to operate and improves the processing efficiency of aerospace wall panel products.

[0010] The lower guard plate of the utility model is fixedly installed on the lower part of the upper guard plate, and is embedded in the limit slot through the limit card plate, thereby increasing the limit fulcrum of the support rod, so that it maintains the horizontal position unchanged and performs axial rotation to avoid its movement and separation, which affects the linkage effect between the components and improves the structural stability.

At the same time, the adsorption area can be adjusted accordingly according to the actual size of the aerospace wall panel product workpiece to prevent air leakage in the unobstructed position of the workpiece, thereby improving the fixing effect of the vacuum suction cup and having a flexible structure.
