Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] In the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] In this embodiment, when fixing the product, the product can be placed above the mounting plate 1. By controlling the operation of the first cylinder 3, the adsorption component 4 can be driven to rise and fall. Multiple adsorption components 4 can be driven to be at different heights by multiple first cylinders 3, so that each adsorption block 41 can be in close contact with different parts of the curved product. By controlling the operation of the vacuum adsorption pump inside the vacuum adsorption pump box 5, the adsorption block 41 can be evacuated through the air guide pipe 6 and the exhaust pipe 43, so that negative pressure is formed in the cavity 42, and the curved product can be adsorbed and fixed, thereby enhancing the applicability of the fixture.

[0033] Among them, through the cooperation of multiple first cylinders 3 and adsorbents 4, each adsorbent 4 can be raised and lowered as needed to adapt to the shape of different curved products, ensuring that each adsorption block 41 is in close contact with various parts of the product, thereby providing a stronger adsorption and fixing force. This design enhances the adaptability to products of different shapes and sizes. The vacuum adsorption pump box 5 provides vacuum through the air guide pipe 6 and the exhaust pipe 43 to ensure that negative pressure is formed in the cavity 42, thereby firmly adsorbing and fixing the product, further improving the stability and fixation of the product, and reducing displacement during processing.

[0034] like Figure 1 and Figure 8 As shown, specifically, the mounting plate 1 is connected with a second cylinder 8 and a third cylinder 9, the second cylinder 8 is connected with a first support block 10, the third cylinder 9 is connected with a second support block 11, the second cylinder 8 is vertically connected to the mounting plate 1, and the third cylinder 9 is obliquely connected to the mounting plate 1; the first support block 10 and the second support block 11 can be driven to rise and fall by the second cylinder 8 and the third cylinder 9, the product can be supported by the first support block 10 and the second support block 11, the second cylinder 8 is vertically connected to the mounting plate 1, the first support block 10 can be driven to support the product plane, the third cylinder 9 is obliquely connected to the mounting plate 1, the second support block 11 can be driven to support the product curved surface, the adjustable inclination angle of the third cylinder 9 and the second support block 11 provides higher flexibility, and can be adjusted according to the curved surface shapes of different products to ensure stable support during processing and avoid deformation or damage caused by uneven support.

[0035] Among them, the third cylinder 9 is detachably connected to the fixing plate 18, and the fixing plate 18 is detachably connected to the mounting plate 1 by bolts. The fixing plate 18 and the third cylinder 9 can be disassembled by bolts, which facilitates the adjustment of the inclination angle of the third cylinder 9 and the second support block 11, thereby enhancing the applicability of the device.

[0036] like Figure 2 and Fig. 9As shown, specifically, the clamping mechanism 7 includes a fourth cylinder 71, the fourth cylinder 71 is connected to the mounting plate 1, a clamping plate 72 is connected above the fourth cylinder 71, and a clamping block 73 is connected below the clamping plate 72; by controlling the operation of the fourth cylinder 71, the clamping plate 72 and the clamping block 73 can be driven to descend, and the product can be squeezed and fixed from above, thereby enhancing the stability of the device.

[0037] Among them, a micro-rotating motor 19 is connected between the fourth cylinder 71 and the pressing plate 72. The micro-rotating motor 19 can drive the pressing plate 72 and the pressing block 73 to rotate. By adjusting the positions of the pressing plate 72 and the pressing block 73, the pressing block 73 can press different positions of the product. Through the combination of the fourth cylinder 71, the pressing plate 72 and the pressing block 73, the product can be pressed evenly, thereby enhancing the stability of the fixture. The addition of the micro-rotating motor 19 can also adjust the position of the pressing block, making the pressing more precise and meeting the needs of different products.

[0038] like Figure 1 and Figure 6 As shown, specifically, an installation groove 44 is opened inside the adsorption block 41, and a rubber sealing ring 45 is arranged inside the installation groove 44, and the installation groove 44 is located outside the cavity 42; by the rubber sealing ring 45 installed in the installation groove 44 contacting with the bottom surface of the product, the sealing between the adsorption component 4 and the product can be enhanced, thereby enhancing the adsorption and fixing effect.

[0039] like Figure 4 and Fig.10 As shown, specifically, a positioning rod 12 and a limiting block 13 are detachably connected to the mounting plate 1; the product can be positioned by the positioning rod 12 and the limiting block 13, so that the product can be placed on the fixture.

[0040] The lower part of the positioning rod 12 is connected to the fifth cylinder 20. The fifth cylinder 20 can drive the positioning rod 12 to rise and fall, and the height of the positioning rod 12 can be adjusted to position products of different specifications.

[0044] Working principle: When fixing the product, the product can be placed above the mounting plate 1. By controlling the operation of the first cylinder 3, the adsorption component 4 can be driven to rise and fall. Multiple adsorption components 4 can be driven to be at different heights by multiple first cylinders 3, so that each adsorption block 41 can be in close contact with different parts of the curved product. By controlling the operation of the vacuum adsorption pump inside the vacuum adsorption pump box 5, the adsorption block 41 can be evacuated through the air guide pipe 6 and the exhaust pipe 43, so that a negative pressure is formed in the cavity 42, and the curved product can be adsorbed and fixed, thereby enhancing the applicability of the fixture.
