Detailed Description

The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:

in the present invention, unless otherwise expressly stated or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally formed; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

In the description of the present invention, it is to be understood that the terms "center", "length", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and the like, indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, are not to be construed as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

As shown in fig. 1 and 2, the negative pressure workpiece fixing tool comprises a placing panel 1, wherein the placing panel 1 is connected with a valve port 2, an air passage communicated with the valve port 2 is arranged in the placing panel 1, a negative pressure groove 4 is arranged on the contact surface of the placing panel 1 and a workpiece, the negative pressure groove 4 is a groove which is transversely and longitudinally interwoven, and the shape and the area of the negative pressure groove 4 are adaptively adjusted according to the workpiece to be processed. Negative pressure groove 4 leads to air vent 3 and gas circuit intercommunication, and the quantity of air vent 3 can be a plurality ofly to the equipartition is in negative pressure groove 4, guarantees the adsorption affinity and the adsorption effect of 4 each positions departments of negative pressure groove.
