Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1 to 10, fig. 1 to 10 disclose an integral sealing ring vacuum adsorption processing device with a replaceable pressing plate, which includes a base 1, a sealing ring 2 and a pressing plate 3, wherein the sealing ring 2 is disposed in a sealing groove 11 of the base 1, the cross section of the sealing ring 2 is L-shaped, the side edge of the L-shape is upward and outward to form an outward turned edge 21, the pressing plate 3 is provided with a plurality of air holes 31, the pressing plate 3 presses an L-shaped bottom surface 22 of the sealing ring 2 on the base 1 and is connected with the base 1 through a fastening member 13, and the air holes 31 are communicated with a vacuum air passage 12 on the base 1. Because the sealing ring 2 in the embodiment has the upward and outward curled edge 21, the sealing effect is better under the vacuum adsorption effect when the processed device is pressed on the sealing ring 2.

Preferably, the sealing ring 2 is an annular sealing ring integrally formed by silica gel or rubber, the annular sealing ring is adopted, and the pressing plate 3 is used for pressing the annular sealing ring, so that the sealing ring cannot be blown out when waste slag is blown by compressed air, and in addition, the annular sealing ring is not provided with a joint, and the problem of air leakage does not exist.

Preferably, the vacuum air duct 12 is formed by a plurality of grooves 122 formed by the protruding strips 121 spaced apart by a predetermined distance and communicating with each other. Of course, the vacuum air duct 12 may be formed by a plurality of air holes with larger diameters arranged on the base 1.

Preferably, the fastening member 13 is a countersunk screw, and the countersunk screw fixedly connects the base 1 and the pressing plate 3 through a countersunk screw hole 32.

Preferably, the curled edge 21 is higher than the upper surface of the pressing plate 3 by a predetermined height H.
