[0002] Graphene is widely used in modern industry, and the common machining method of the existing graphene plate is to fix the graphene plate on the workbench of a machining machine tool, to machine the graphene according to the characteristics of the graphene and the shape and size required to be machined. Since the hardness of the graphene is not large, the graphene plate is easily deformed by being pressed and fixed on the workbench with a pressing block. In order to prevent the graphene plate from being deformed by being pressed, the graphene plate is usually glued to a fixed plate in the industry when machining the graphene plate, and the fixed plate is then fixed on the workbench to machine the graphene plate. Although this method can prevent the graphene plate from being deformed by being pressed, it is still necessary to use a degreasing agent to degrease the machined graphene plate after machining, which is low in production efficiency and increases the production cycle of the product. SUMMARY

[0005] The further technical scheme of the utility model discloses that the air passage includes the main air passage in the middle part and the branch air passage that is connected in the symmetry of the two sides of main air passage, and one end of the main air passage is connected with the air pipe. The upper surface of the positioning bottom plate is provided with two rows of plate processing positions, and the two rows of plate processing positions are symmetrically arranged on the two sides of the central axis of the main air passage. The two air passage holes of the same air passage groove in each plate processing position are connected with the same branch air passage.
[0006] A further technical solution of this utility model is: one end of the main airway penetrates one side wall of the positioning base plate, the air pipe is connected to the main airway that penetrates the side wall of the positioning base plate, and the branch airways on one side of the central axis of the main airway extend outward and penetrate one side wall of the positioning base plate respectively. The ends of the branch airways that penetrate the side wall of the positioning base plate are sealed with sealing bolts.
[0007] A further technical solution of this utility model is: the positioning post is a circular positioning post, and the ventilation grooves on both sides of the two positioning posts in each plate processing position are symmetrically arranged on both sides of the line connecting the axes of the two positioning posts.
[0008] A further technical solution of this utility model is: in each plate processing position, an inner sealant mounting groove is provided on the outside of the two positioning posts, which is located on the inside of the outer sealant mounting groove and on the outside of the two ventilation grooves. An inner sealant strip is provided in the inner sealant mounting groove.
[0009] This utility model provides a machining fixture for graphene sheets with the following advantages: By setting air channels within a positioning base plate, and multiple sheet machining positions on the upper surface of the positioning base plate, symmetrical air grooves are arranged on both sides of the positioning posts of the sheet machining positions. Air holes are set in the air grooves and connected to the air channels. When the graphene sheet to be processed is placed on the sheet machining position, simply controlling the vacuum pump to draw air will allow the graphene sheet to adhere tightly to the positioning plane of the sheet machining position. This eliminates the need for clamping the graphene sheet with a clamping device, allowing for machining without the need for clamping. By controlling the vacuum pump to release air, the graphene sheet can be removed from the positioning plane without being adsorbed. The tooling is simple in design, and the workpiece can be installed and positioned quickly and accurately, effectively preventing the graphene sheet from being deformed by pressure. At the same time, because ventilation grooves and air holes are symmetrically set on both sides of the positioning post, the adsorption force on both sides of the graphene sheet is basically the same when it is positioned on the sheet processing position. The graphene sheet is subjected to uniform force and can be firmly attached to the sheet processing position during the processing process, making it less likely to fall off, effectively ensuring processing quality and efficiency.
