[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figure 1 and Figure 3As shown, a novel lifting and rotating cylinder structure comprises: a cylinder body 1 and a cylinder shaft 2. The cylinder shaft 2 is movably arranged inside the cylinder body 1, and its first end extends from the first end face of the cylinder body 1 to the outside of the cylinder body 1, and its second end extends from the second end face of the cylinder body 1 to the outside of the cylinder body 1. End covers 10 are arranged at both ends of the cylinder body 1, and linear bearings 13 are arranged between the cylinder shaft 2 and the end covers 10. The two linear bearings 13 perform precise guiding functions and radial load bearing functions.

[0024] A rotating driving wheel 3 is rotatably arranged on the outer periphery of the first end surface of the cylinder body 1, and a plurality of driving rods 4 which rotate synchronously with the rotating driving wheel 3 are arranged on the side away from the cylinder body 1, and a driving lifting plate 5 is slidably arranged on the driving rod 4. The driving lifting plate 5 rotates synchronously with the driving rod 4.

[0025] The side of the rotating driving wheel 3 away from the cylinder body 1 is provided with a driving fixing plate 14 that rotates synchronously therewith, and the driving rod 4 is fixedly arranged on the driving fixing plate 14. In this embodiment, there are three driving rods 4 that are evenly distributed along the circumference of the cylinder shaft 2.

[0026] Furthermore, a limit fixing ring 8 is fixedly provided at the end of the driving rod 4 away from the cylinder body 1. The limit fixing ring 8 can fix the parallelism of the axes of the three driving rods 4 to prevent the driving lifting plate 5 from sliding and getting stuck. At the same time, it also plays a limiting role to prevent the driving lifting plate 5 from being separated from the three driving rods 4.

[0027] like Figure 2 As shown, the driving lifting plate 5 has a connection hole 11 in the center and a plurality of guide grooves 12 at the edge. The guide grooves 12 are adapted to the driving rod 4 to achieve a sliding connection between the driving lifting plate 5 and the driving rod 4, and rotate synchronously with the driving rod 4. The connection hole 11 is used to connect the cylinder shaft 2.

[0028] like Figure 4 and Figure 5 As shown, the cylinder shaft 2 includes an inner shaft 6 and an outer shaft 7. The inner shaft 6 is rotatably arranged inside the outer shaft 7, and both ends extend to the outside of the outer shaft 7. The first end of the inner shaft 6 extending to the outside of the outer shaft 7 is connected to the driving lifting plate 5 to rotate synchronously therewith. Specifically, the first end of the inner shaft 6 is inserted into the connecting hole 11 in the center of the driving lifting plate 5, and is fixedly connected to the driving lifting plate 5 through the mounting plate.

[0029] Preferably, the inner shaft 6 is hollow inside. The hollow central rotating shaft can be provided with additional functions such as water flow, ventilation, vacuum adsorption, water cooling, etc.

[0030] A centering mechanism 9 is provided on the outer periphery of the second end of the inner shaft 6 extending to the outer side of the outer shaft 7 to reduce the end face runout of the rotation action and increase the processing accuracy. The accompanying drawing shows a drum-type spline.

[0031] Under the action of the rotary bearing and the needle bearing, the inner shaft 6 and the driving lifting plate 5 can follow the cylinder shaft 2 to rise and fall, but retain the function of rotation. When the rotation action is completed, the external motor drives the rotating driving wheel 3 to rotate, driving the driving fixed plate 14 and the driving rod 4 to rotate, and then drives the driving lifting plate 5 with the guide groove to rotate, driving the inner shaft 6 to rotate, and can simultaneously complete the actively driven rotation movement and linear feed movement.

[0032] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
