[0056] Second embodiment

[0057] Please refer to Figure 6-Figure 7 , Figure 6 A schematic structural diagram of a second embodiment of the high-speed assembly line lifting, tightening and rotating device provided by the present invention; Figure 7 The present invention provides a schematic diagram of the structure of the guide rail. Based on the high-speed assembly line lifting, tightening and rotating device provided in the first embodiment of the present application, the second embodiment of the present application proposes another high-speed assembly line lifting, tightening and rotating device. The second embodiment is only a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0058] Specifically, the high-speed assembly line lifting, tightening and rotating device provided in the second embodiment of the present application is different in that a fixing ring 31 is installed on the outer surface of the fixing tube 9 by bolts 38, and a guide rail 32 is fixedly connected to the opposite side of the outer surface of the fixing ring 31;

[0059] In order to increase stability, both ends of the guide rail 32 can be connected to the outer surface of the fixing tube 9 through a fixing ring, as long as the up and down movement and rotation of the fixing tube 9 are not affected.

[0060] The outer surface of the fixed ring 31 is provided with a rotating ring 37, and the outer surface of the rotating ring 37 is installed with a bearing 35;

[0061] There is a certain distance between the rotating ring 37 and the fixed ring 31 , and the rotating ring 37 will rotate with the fixed tube 9 , but will not move up and down with the fixed tube 9 .

[0062] The inner surface of the rotating ring 37 has a buckle 28 fixedly connected to one side opposite to the inner surface of the rotating ring 37, and the other side of the buckle 28 has a sliding groove 39;

[0063] The buckle 28 is sleeved on the outer surface of the guide rail 32 through the slide groove 39 , so that the rotating ring 37 can be installed on the outer surface of the fixed ring 31 .

[0064] A snap ring 36 is mounted on the outer surface of the rotating ring 37, and four mounting plates 34 with mounting holes 33 are mounted on the outer surface of the snap ring 36;

[0065] The mounting holes 33 on the mounting plate 34 are for the convenience of the bolts 38 to pass through. The clamping ring 36 can be mounted on the inner wall of the pipe that allows the fixed pipe 9 to move up and down through the mounting plate 34, thereby assisting the fixed pipe 9 to move up and down and increasing stability.

When the fixed tube 9 needs to move up and down, the buckle 28 and the guide rail 32 inside the rotating ring 37 cooperate with each other to increase the stability of the up and down movement of the fixed tube 9. When the fixed tube 9 needs to rotate, the bearing 35 cooperates with the structure of the inner surface of the rotating ring 37 to increase the stability of the rotation. This design is conducive to increasing the stability of the fixed tube 9 in the up and down movement, thereby increasing the accuracy of tensioning and rotation of the high-speed assembly line.
