Detailed Description
The features of the present invention and other related features are described in further detail below by way of example in conjunction with the accompanying drawings to facilitate understanding by those skilled in the art:
as shown in fig. 1-2, reference numerals 1-15 in the drawings are respectively expressed as: the cylinder comprises a cylinder body 1, a cylinder piston 2, a cylinder connecting rod 3, a cylinder chamber 4, a cylinder body front end 5, a cylinder connecting rod mounting hole 6, a dynamic sealing ring 7, a cooling water channel 8, a cooling water connector 9, a cooling water inlet connector 10, a cooling water outlet connector 11, a breathing hole 12, a first cylinder air inlet and outlet connector 13, a second cylinder air inlet and outlet connector 14 and a static sealing ring 15.
Example (b): the vacuum cylinder protected by the multi-channel vacuum sealing and water cooling structure in the embodiment can still keep good dynamic and static sealing performance for a long time under the condition of heating vacuum. As shown in fig. 1 and 2, the vacuum cylinder mainly includes a cylinder body 1, a cylinder piston 2, a cylinder connecting rod 3, a dynamic seal ring 7 and a cooling water channel 8, the cylinder body 1 mainly includes a cylinder barrel 4 and a cylinder body front end 5, the cylinder piston 2 is disposed in the cylinder barrel 4 and connected to the cylinder connecting rod 3, and the cylinder connecting rod 3 extends to the outside of the cylinder body 1 through a cylinder connecting rod mounting hole 6 disposed in the middle of the cylinder body front end 5.
As shown in fig. 1, the cylinder tube 4 is provided with a first cylinder inlet/outlet port connector 13 and a second cylinder inlet/outlet port connector 14. When compressed gas enters the cylinder barrel 4 from the first cylinder gas inlet and outlet port connector 13, the compressed gas pushes the cylinder piston 2 to move, then gas in the cylinder barrel 4 close to the second cylinder gas inlet and outlet port connector 14 is discharged from the second cylinder gas inlet and outlet port connector 14, and finally the cylinder piston 2 drives the cylinder connecting rod 3 to move outwards the cylinder barrel 4; when compressed gas enters the cylinder barrel 4 through the second cylinder gas inlet and outlet port connector 14, the compressed gas pushes the cylinder piston 2 to move, then gas in the cylinder barrel 4 close to the first cylinder gas inlet and outlet port connector 13 is discharged from the first cylinder gas inlet and outlet port connector 13, and finally the cylinder piston 2 drives the cylinder connecting rod 3 to move towards the inside of the cylinder barrel 4. Accordingly, the cylinder rod 3 can reciprocate in the length direction of the cylinder rod mounting hole 6.
As shown in fig. 1, the inner wall of the cylinder connecting rod mounting hole 6 is provided with a plurality of groups of grooves which are uniformly spaced, each groove is provided with a dynamic seal ring 7 which is matched with the groove, and the dynamic seal ring 7 is sleeved on the outer wall of the cylinder connecting rod 3 and forms a dynamic seal structure with the cylinder connecting rod 3. Through setting up multichannel movable seal circle 7, when cylinder connecting rod 3 was in the motion state, can keep this cylinder self good dynamic seal performance to vacuum degree change is little when making vacuum coating, and is little to the process of making a layer.
As shown in fig. 1 and 2, the front end 5 of the cylinder block is provided with an annular cooling water channel 8 along the periphery of the dynamic seal ring 7, and the cooling water channel 8 is arranged around the dynamic seal ring 7 and can be spirally arranged along the extending direction of the plurality of dynamic seal rings 7. And a cooling water joint 9 is arranged on the cooling water channel 8, and the cooling water joint 9 comprises a cooling water inlet joint 10 and a cooling water outlet joint 11. When the vacuum cylinder is used, cooling water can enter the cooling water channel 8 through the cooling water inlet connector 10, the heat of the front end 5 of the cylinder body, the dynamic sealing ring 7 and the cylinder connecting rod 3 is taken away through the cooling water channel 8, and finally the heat flows out through the cooling water outlet connector 11, so that the dynamic sealing ring 7 is protected, and the vacuum cylinder is further guaranteed to keep good static and dynamic sealing performance for a long time under a high-temperature condition.
As shown in fig. 1, a breathing hole 12 is formed in the front end 5 of the cylinder block, and the breathing hole 12 penetrates through the cylinder block 1 and extends to the cylinder connecting rod 3. Meanwhile, as the cylinder connecting rod 3 moves in the cylinder connecting rod mounting hole 6, friction is easy to generate, and grease or lubricant can be injected into the breathing hole 12 at the moment to play a lubricating role. That is, the hole provided in the cylinder block front end 5 can be used as a breather hole or a grease injection hole.
As shown in fig. 1, a static sealing ring 15 is installed on the front end 5 of the cylinder body to ensure the sealing performance of the vacuum cylinder when the vacuum cylinder is integrally installed, for example, the sealing performance of the vacuum cylinder when the vacuum cylinder is installed in a vacuum coating apparatus.
In the embodiment, in specific implementation: the movable sealing ring 7 adopts a fluororubber O-shaped ring and is provided with a cylinder water cooling structure, so that the movable sealing ring can be directly assembled in a high-temperature vacuum system for stable use; in the action process of the cylinder, the air tightness in a dynamic sealing state is good, the change of the vacuum degree is small, and the influence on a layer making process is small; the guiding and the repeatability are good; the durability is good.
Although the conception and the embodiments of the present invention have been described in detail with reference to the drawings, those skilled in the art will recognize that various changes and modifications can be made therein without departing from the scope of the appended claims, and therefore, the description thereof is not repeated herein.
