[0017] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0018] like Figure 1 to Figure 2 As shown, in this embodiment, a multi-axis linkage rotation and independent lifting structure includes a fixed plate 1, a driving shaft 2, a plurality of driven shafts 3, a connecting plate 4 and a plurality of lifting shafts 5. The driving shaft 2 and the plurality of driven shafts 3 are rotatably connected to the fixed plate 1. A main synchronous wheel 6 is installed on the driving shaft 2, and a slave synchronous wheel 7 is installed on each driven shaft 3. The main synchronous wheel 6 is transmission-connected with the plurality of slave synchronous wheels 7. A lifting power cylinder 8 is fixed on the fixed plate 1. The number of the lifting power cylinders 8 and the number of the lifting shafts 5 are consistent with the number of the driven shafts 3. The driving end of a lifting power cylinder 8 is connected to the upper end of a lifting shaft 5. The lower end of the driven shaft 3 is moved along the vertical direction with a driving shaft 9. The driving shaft 9 is rotatably connected to one side of the connecting plate 4, and the lower end of the lifting shaft 5 is connected to the other side of the connecting plate 4.

[0019] The driving shaft 2 provides power for rotation, and transmits the rotational power to the driven shaft 3 in real time through the connection between the main synchronous wheel 6 and the slave synchronous wheel 7, so that the driving shaft 9 connected under the driven shaft 3 can drive the tool to rotate. A single driving shaft 2 links multiple driving shafts 9 to rotate synchronously, saving space and reducing costs. In terms of lifting, the lifting power cylinder 8 independently controls the lifting and lowering of each driving shaft 9.

[0020] A synchronous belt 10 is connected between the main synchronous wheel 6 and the slave synchronous wheel 7. The power of the driving shaft 2 causes the main synchronous wheel 6 to rotate, and the driven shaft 3 with the slave synchronous wheel 7 is controlled to rotate through the synchronous transmission of the synchronous belt 10, thereby causing the driving shaft 9 to rotate.

[0021] A first bearing 11 is installed on the fixed plate 1, and the driving shaft 2 is rotatably connected to the first bearing 11. A second bearing 12 is installed on the fixed plate 1, and the driven shaft 3 is rotatably connected to the second bearing 12. In order to reduce friction, the first bearing 11 and the second bearing 12 are used to control the rotation of the driving shaft 2 and the driven shaft 3 on the fixed plate 1 respectively.

[0022] A connecting shaft 13 is connected to the connecting plate 4, and a sliding groove 14 is arranged on the connecting shaft 13 along the vertical direction. A limiting shaft 15 is placed in the sliding groove 14. The limiting shaft 15 passes through the sliding groove 14 and is locked at the lower end of the driven shaft 3. The lower end of the connecting shaft 13 is fixedly connected to the upper end of the driving shaft 9. Since the driving shaft 2 and the driven shaft 3 require real-time synchronous transmission, the driven shaft 3 cannot be lifted up and down. The connecting shaft 13 is added to drive the lifting and lowering of the driving shaft 9. During the lifting process, the limiting shaft 15 moves in the sliding groove 14 to ensure that the connecting shaft 13 with the driving shaft 9 is always connected to the driven shaft 3.

[0023] A third bearing 16 is installed on the connecting plate 4, and the driving shaft 9 is rotatably connected to the third bearing 16. Since the connecting plate 4 will move up and down with the lifting shaft 5, the driving shaft 9 can rotate during the lifting process under the action of the third bearing 16.

[0024] It should be stated that the above-mentioned specific implementation methods are only preferred embodiments of the present utility model and the technical principles used. Within the technical scope disclosed by the present utility model, any changes or substitutions that can be easily thought of by technicians familiar with this technical field should be included in the protection scope of the present utility model.
