In an integrated implementation, as shown in fig. 5 and 6, the rotary suction device 3 includes a suction cup 324 and a bottom plate 323 connected to the suction cup 324, wherein an annular groove 321 is formed between the bottom plate 323 and the suction cup 324; the adsorption hole group further comprises a second communication hole 325 and a third communication hole 326, one end of the first communication hole 312 is communicated with the annular groove 321, the other end of the first communication hole 312 is communicated with the second communication hole 325, one end of the third communication hole 326 is communicated with one end, far away from the first communication hole 312, of the annular groove 321, and the other end of the third communication hole 326 is communicated with an external vacuum device.
The process of the rotary adsorption device 3 is as follows: the second communication hole 325 is formed upward from the bottom of the suction cup 324, the third communication hole 326 is formed at the upper portion of the suction cup 324 from the side, the third communication hole 326 and the external environment can be sealed by a sealing member such as a plug, and the suction hole 322 is formed at the top of the suction cup 324, so that all holes of the suction cup 324 are horizontal holes or vertical holes, and the processing process is simple. The bottom plate 323 and the suction cup 324 may be separate components or may be connected as a whole, for example, the bottom plate 323 and the suction cup 324 may be separate components and may be connected and sealed by screws or fastening glue, and preferably, an annular groove 321 is formed at the connection between the bottom plate 323 and the suction cup 324; after the second communication hole 325, the third communication hole 326 and the suction hole 322 are formed in the suction cup 324, the base plate 323 is connected by welding or the like, and the annular groove 321 is formed between the base plate 323 and the suction cup 324, thereby reducing the manufacturing process and manufacturing cost of the rotary suction device 3. And the external vacuum device is fixed relative to the base plate 323 and does not rotate along with the rotation of the suction cup 324, so that the external vacuum device does not need to be limited by the size of the rotary suction device 3 or the power of the first driving member 2 and the second driving member 2, and a larger-power external vacuum device can be selected to enable the suction cup 324 to have larger suction force on a processed workpiece, thereby increasing the applicability of the rotary working platform.
In a specific embodiment, as shown in fig. 5 and 6, the sealing assembly includes a first sealing element 34 and a second sealing element 35, the first sealing element 34 and the second sealing element 35 are disposed along an axial direction of the annular groove 321, and the annular groove 321 is disposed between the first sealing element 34 and the second sealing element 35. The first sealing member 34 is installed between the suction cup 324 and the inner sidewall of the mounting hole 311, and the second sealing member 35 is installed between the bottom plate 323 and the inner sidewall of the mounting hole 311; in the axial direction of the suction cup 324, the annular groove 321 is located between the first seal 34 and the second seal 35. It will be appreciated that the first seal 34 and the second seal 35 may be used to seal the communication between the first communication hole 312 and the annular groove 321. Preferably, the first seal 34 and the second seal 35 are both framework oil seals. It should be noted that the sealing assembly seals the annular groove 321 radially, i.e. the communication between the first communication hole 312 and the annular groove 321 is sealed radially by the sealing assembly, specifically, radially of the sealing assembly, and may also be perpendicular to the second axis.
Specifically, the first sealing element 34 is hermetically installed between the suction cup 324 and the inner side wall of the second base 31, and the lip of the first sealing element 34 abuts against the outer wall of the suction cup 324; the second sealing member 35 is sealingly installed between the bottom plate 323 and the inner side wall of the second base 31, and the lip of the second sealing member 35 abuts against the outer wall of the bottom plate 323. The first seal 34 and the second seal 35 can ensure the sealing performance of the rotary adsorption device 3 in the process of high-speed rotation of the rotary adsorption device 3, so that the rotary working platform can process a processed workpiece at high speed and high precision. In addition, the first sealing element 34 and the second sealing element 35 have elasticity due to their own lips, and the friction force between the first sealing element 34 and the rotary adsorption assembly 32 can be reduced by their own elastic force in the high-speed rotation mode, so that the heat generation amount of the first sealing element 34 and the second sealing element 35 is reduced, and further the first sealing element 34 and the second sealing element 35 do not need to be frequently disassembled, thereby prolonging the service life of the rotary working platform.
In another embodiment, the second base 31 is provided with a first sealing member groove and a second sealing member groove, the first communication hole 312 is disposed between the first sealing member groove and the second sealing member groove, the first sealing member groove receives the first sealing member 34, and the second sealing member groove receives the second sealing member 35.

It is to be understood that the second communication holes 325 are distributed in the vertical direction, and the third communication holes 326 and the first communication holes 312 are arranged in the horizontal direction. Further, the adsorption holes 322 are also distributed in a vertical direction, and the annular groove 321 opens toward the first communication hole 312. In this embodiment, the rotary adsorption device 33 has a simple processing process and a low manufacturing cost.
In one embodiment, as shown in fig. 8 and 9, the suction cup 324 further has a plurality of coaxially distributed annular grooves 327, and the suction holes 322 are disposed in the annular grooves 327. It is understood that the annular groove 327 is formed on the upper surface of the suction cup 324, and the suction hole 322 is formed at the bottom of the annular groove 327. In this embodiment, the annular groove 327 transforms the processed plane from a continuous plane to a discontinuous plane, so that the processing precision of the processing plane of the suction cup 324 can be significantly improved, and the interior of the annular groove 327 does not need to be finished; in addition, the fine machining surface of the suction cup 324 is not required to be machined with the suction hole 322, and the suction hole 322 is only required to be machined at the bottom of the annular groove 327, so that the situation that the fine machining effect of the suction cup 324 is affected by the burrs generated by machining the suction hole 322 on the fine machining surface of the suction cup 324 is avoided.
In an embodiment, the rotary suction device 3 further includes a plug (not shown) for sealing the third communication hole 326, and the plug is sealingly installed in the third communication hole 326. It is understood that one end of the third communication hole 326 is connected to the external environment before the plug does not plug the third communication hole 326, and after the third communication hole 326 is processed, the plug is used to plug the third communication hole 326, thereby preventing the third communication hole 326 from being directly connected to the external environment. In this embodiment, the design of the plug ensures the sealing performance of the rotary adsorption device 3 and reduces the manufacturing cost of the rotary adsorption device 3.
