[0005] Preferably, the sealing material is foam.

[0006] Preferably, through holes are formed in the foam.

[0007] Preferably, a limiting groove is formed on the surface of the fixing base where the sealing material is arranged, and the sealing material is located in the limiting groove.

[0008] Preferably, the thickness of the sealing material is greater than the depth of the limiting groove.

[0009] Preferably, the positions of the through holes correspond to the positions of the suction holes.

[0010] Compared with the prior art, the advantages and positive effects of the utility model are as follows:

[0011] 1. The fixing device for workpiece processing provided by the utility model realizes vacuum adsorption by fitting the fixing base to the surface of the workpiece and sucking air through the vacuum source. The sealing material can improve the sealing performance between the fixing base and the workpiece when the fixing base fixes the workpiece, improve the vacuum degree, and ensure the fixing effect.

[0012] 2. The workpiece processing and fixing device provided by the present utility model can fill the uneven parts on the surface of the workpiece through the deformation of the foam under the adsorption effect, ensuring the sealing performance between the fixing seat and the workpiece, improving the vacuum degree, and ensuring the fixing effect.

[0018] The following will clearly and completely describe the technical solutions of the present utility model in conjunction with the drawings. Obviously, the described embodiments are some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the protection scope of the present utility model.

[0019] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model 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 should not be construed as a limitation to the present utility model.

[0020] Embodiment 1:

[0021] Please refer to Figure 1, a workpiece processing and fixing device provided by the utility model includes a fixing base 1, and the fixing base 1 is provided with an air duct connected to a vacuum source; the fixing base 1 is provided with suction holes 2 communicating with the inside of the air duct; one side of the fixing base 1 is provided with a sealing material 3, and the sealing material 3 is used to improve the sealing performance between the fixing base 1 and the workpiece when the fixing base 1 fixes the workpiece.

[0022] By making the fixing base 1 fit the surface of the workpiece and sucking air through the vacuum source, vacuum adsorption is achieved, and the sealing material 3 can improve the sealing performance between the fixing base 1 and the workpiece when the fixing base 1 fixes the workpiece, improve the vacuum degree, and ensure the fixing effect.

[0023] In this embodiment, the sealing material 3 is foam.

[0024] When the surface of the workpiece is uneven, such as rough or with micro-grooves, the foam will deform under the adsorption effect to fill the uneven places, ensuring the sealing performance between the fixing base 1 and the workpiece, improving the vacuum degree, and ensuring the fixing effect.

[0025] In this embodiment, through holes 4 are formed in the foam.

[0026] The through holes 4 in the foam can ensure the flow of gas.

[0027] In this embodiment, a limiting groove 5 is formed on one side of the fixing base 1 where the sealing material 3 is provided, and the sealing material 3 is located in the limiting groove 5.

[0028] The sealing material 3 is arranged in the limiting groove 5, which can improve the stability of the sealing material 3 and prevent it from falling off.

[0029] In this embodiment, the thickness of the sealing material 3 is greater than the depth of the limiting groove 5.

[0030] The thickness of the sealing material 3 being greater than the depth of the limiting groove 5 can prevent the sealing material 3 from being entirely within the limiting groove 5 and unable to provide a sealing effect.

[0031] In this embodiment, the through holes 4 correspond to the positions of the suction holes 2.

[0032] With the through holes 4 corresponding to the positions of the suction holes 2 and the vacuum source, an adsorption force can be generated at the through holes 4 to adsorb and fix the workpiece.

[0033] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
