[0031] As Figure 1 shown in FIGS. 6 - 7, a rotating mechanism with damping includes a rotating shaft 1, bearings 2, a bearing housing 3, a friction damping assembly 4, a rigid positioning assembly 5 and a starting positioning assembly 6. The rotating shaft 1 is disposed within the bearing housing 3, the bearings 2 are provided between the rotating shaft 1 and the bearing housing 3 in a supporting manner, the rotating part of the friction damping assembly 4 is connected to the front end of the rotating shaft 1, and the stationary part of the friction damping assembly 4 is connected to the front end of the bearing housing 3; the rigid positioning assembly 5 is disposed on the bearing housing 3 and is used to lock the rotating shaft 1 when the rotating shaft 1 rotates to at least one specific angle; the starting positioning assembly 6 is used to set the initial position of the rotating shaft 1 and adjust the rotation direction.

[0032] It should be noted that the number of the bearings 2 is two, and the two bearings 2 support the rotating shaft 1 one in front of the other.

[0033] In this embodiment, the rigid positioning assembly 5 includes a positioning plunger 18. A plunger hole 7 is formed in the bearing block 3, and a plurality of positioning holes 8 corresponding to different specific rotation angles are formed in the rotating shaft 1. The positioning plunger 18 is installed in the plunger hole 7, and the front end of the positioning plunger 18 can be inserted into the positioning hole 8 on the rotating shaft 1 to lock the rotating shaft 1.

[0034] It should be noted that plunger holes 7 are formed on both the upper and lower surfaces of the bearing block 3. During actual use, the positioning plunger 18 can be installed in any one of the plunger holes 7 according to actual needs. In this embodiment, three positioning holes 8 are formed on the rotating shaft 1, which respectively represent three specific angles of rotation of the rotating shaft 1. When the plunger hole 7 and the positioning hole 8 are coaxially aligned, the rotating shaft 1 can be locked by inserting the positioning plunger 18 into the positioning hole 8 to keep it stationary.

[0035] In this embodiment, the starting positioning assembly 6 includes an adjustable positioning plate 9 and a rigid positioning plate 10. The adjustable positioning plate 9 is installed on the side wall of the bearing block 3, and the vertical position of the adjustable positioning plate 9 is adjustable. The rigid positioning plate 10 is installed on one side of the rear end of the rotating shaft 1. The rigid positioning plate 10 and the adjustable positioning plate 9 can be abutted against each other. When the rigid positioning plate 10 and the adjustable positioning plate 9 are abutted against each other, the rigid positioning plate 10 drives the rotating shaft 1 to rotate to the initial position.

[0036] It should be noted that a long slot is formed in the adjustable positioning plate 9. The vertical position of the adjustable positioning plate 9 is adjusted by fixing screws at different positions in the long slot. By changing the position of the adjustable positioning plate 9, the abutting position between the rigid positioning plate 10 and the adjustable positioning plate 9 can be changed, so as to change the initial position of the rotating shaft 1. Whether the rigid positioning plate 10 abuts against the upper side or the lower side of the adjustable positioning plate 9 determines the direction in which the rotating shaft 1 can rotate, realizing the adjustment and limitation of the direction of the rotating shaft 1 by the adjustable positioning plate 9.

[0037] In this embodiment, a set screw 11 is installed on the rigid positioning plate 10, and the set screw 11 is used to adjust the abutting distance between the rigid positioning plate 10 and the adjustable positioning plate 9.

[0038] By installing the set screw 11, the initial position of the rotating shaft 1 can be adjusted by the set screw 11.

[0039] In this embodiment, the rotating part of the friction damping assembly 4 includes a driving plate 12, an inner pressure plate 13 and an outer pressure plate 14. The stationary part of the friction damping assembly 4 includes a fixing ring 15. The fixing ring 15 is connected to the rear end of the bearing block 3. The inner pressure plate 13 and the outer pressure plate 14 are clamped on both sides of the fixing ring 15. The driving plate 12 is connected to the rear end of the rotating shaft 1. The driving plate 12, the inner pressure plate 13 and the outer pressure plate 14 are connected into one body by a damping adjustment screw 16.

[0040] In this embodiment, a friction plate 17 is installed between the inner pressing plate 13 and the fixing ring 15, and a friction plate 17 is installed between the outer pressing plate 14 and the fixing ring 15.

[0041] In this embodiment, the head of the damping adjustment screw 16 presses on the outer pressing plate 14, and a disc spring 19 is provided between the head of the damping adjustment screw 16 and the outer pressing plate 14.

[0042] It should be noted that when the friction damping assembly 4 works, damping is provided by the friction of the friction plate 17 on the inner side of the inner pressing plate 13 and the friction plate 17 on the inner side of the outer pressing plate 14 against the fixing ring 15. By adjusting the tightness of the damping adjustment screw 16, the clamping force is adjusted, and thus the magnitude of the friction damping is adjusted.

[0043] The above are only the preferred embodiments of the present invention, and do not impose any limitations on the present invention. Any simple modifications, changes, and equivalent structural changes made to the above embodiments according to the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
