Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, and all other embodiments obtained by those skilled in the art without making any creative effort, belong to the protection scope of the present invention.
Referring to fig. 1 to 3, the present invention provides a technical solution: a sealing structure and a numerical control cutter PVD coating processing air inlet device comprise a fixing frame 1, wherein the fixing frame 1 is fixedly arranged at an air inlet of the PVD coating processing air inlet device;
the lifting seat 3 is arranged below the fixing frame 1 and is in sliding connection with the fixing frame 1.
The middle part below the fixing frame 1 is fixedly connected with a resisting block 11, and the outer radius of the resisting block 11 is smaller than that of the fixing frame 1.
The lower part of the abutting block 11 is fixedly connected with the top of the spring 4, the bottom of the spring 4 is fixedly connected with the upper inner wall of the lifting seat 3, the upper inner wall of the lifting seat 3 is matched with the side wall of the abutting block 11, and the upper inner wall and the side wall are in sealing connection through a sealing ring 31.
The top middle part of lift seat 3 and the bottom fixed connection of intake pipe 2, the vertical middle part that passes mount 1 in the top of intake pipe 2 to with the vertical sliding connection of mount 1, both sliding connection departments are provided with sealed the pad, the outside end of intake pipe 2 is provided with external force pump.
Be provided with a plurality of evenly distributed's circulation mouth 21 on the below lateral wall of intake pipe 2, intake pipe 2 is located fixedly connected with connecting plate 22 on the lateral wall of mount 1 top.
