DETAILED DESCRIPTION

[0011] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention.

[0012] like Figures 1 to 3 As shown, the present invention includes a driving part and an action part, the action part includes a bracket 1, an adjusting wheel 2 and a swing wheel 3, the bracket 1 supports the adjusting wheel 2 and the swing wheel 3, the swing wheel 3 is arranged on the periphery of the adjusting wheel 2, the adjusting wheel 2 is meshed with the swing wheel 3 and drives the swing wheel 3 to rotate, and the swing wheel 3 is connected to a swing arm 4 below; The driving part includes a housing 5, a driving shaft 6, an adjustment mechanism 7 and a transmission mechanism. The adjustment mechanism 7 and the transmission mechanism are arranged in the housing 5. A driving motor 15 is arranged above the housing 5. The top end of the driving shaft 6 passes through the housing 5. The top end of the driving shaft 6 is connected to the driving motor 15. The driving motor 15 drives the driving shaft 6 to rotate. The bottom end of the driving shaft 6 passes through the housing 5 and the axial hole in the center of the adjusting wheel 2. The axial hole is a through hole opened at the axis of the central axis of the adjusting wheel. The power input end of the transmission mechanism is connected to the driving shaft 6, and the output end is connected to the adjusting wheel 2. The adjusting wheel 2 is sleeved outside the driving shaft 6, and the adjusting wheel 2 is coaxially set with the driving shaft 6. The adjustment mechanism 7 is connected to the transmission mechanism. Through the above arrangement, the bottom end of the driving shaft 6 can be used as a source of rotational power. At the same time, the driving part drives the transmission mechanism to drive the adjusting wheel 2 to move, and the swing wheel 3 is driven to move through the adjusting wheel 2. Finally, it is achieved that the opening and closing of the swing arm 4 is controlled by controlling the transmission mechanism without affecting the rotational movement of the driving shaft 6.

[0013] Specifically, the transmission mechanism includes a primary planetary gear assembly 8, a support frame 9, a secondary planetary gear assembly 10 and a transmission shaft sleeve, wherein the primary planetary gear assembly 8, the support frame 9, the secondary planetary gear assembly 10, the transmission shaft sleeve and the adjustment wheel 2 are coaxially arranged, and the primary planetary gear assembly includes three planetary gears 12, a sun gear 13 and a ring gear 14, and the structure of the secondary planetary gear assembly is the same as that of the primary planetary gear assembly; The drive shaft 6 passes through the sun gear 13 of the first-stage planetary gear assembly 8, the support frame 9, the sun gear 13 of the second-stage planetary gear assembly 10, the transmission sleeve and the adjustment wheel 2 from top to bottom. The sun gear 13 of the first-stage planetary gear assembly 8 is connected to the drive shaft 6 by a key and realizes synchronous movement. The sun gear 13 of the second-stage planetary gear assembly 10 is sleeved outside the drive shaft 6 and is not connected. The sun gear 13 of the second-stage planetary assembly is fixed to the top of the transmission sleeve, and the bottom of the transmission sleeve extends outside the housing 5 and is fixed to the central axis of the adjustment wheel 2. Preferably, the sun gear 13 of the second-stage planetary gear and the transmission sleeve are an integrally formed structure. The transmission sleeve is a cylindrical structure, and a through hole is provided in the middle of the transmission sleeve, and the drive shaft 6 passes through the through hole.

[0014] The middle part of the support frame 9 is connected to the driving shaft 6 through a bearing, and three shaft holes are arranged on the periphery of the support frame 9, and a connecting shaft 19 is arranged in each of the three shaft holes of the support frame 9, and the two ends of the connecting shaft 19 are respectively connected to the central axis of the planetary gear 12 of the primary planetary gear assembly and the central axis of the planetary gear 12 of the secondary planetary gear assembly; Through the above arrangement, when the drive shaft 6 rotates, the sun gear 13 of the first-stage planetary gear assembly 8 rotates synchronously with the drive shaft 6, and the planetary gear 12 of the first-stage planetary gear assembly 8 also rotates with the sun gear 13 meshed therewith. Since the first-stage planetary gear assembly 8 and the second-stage planetary gear assembly 10 have the same structure, the planetary gear 12 of the first-stage planetary gear assembly 8 drives the planetary gear 12 of the second-stage planetary gear assembly 10 to rotate under the action of the connecting shaft 19. Since the sun gear 13 of the second-stage planetary gear assembly 10 is sleeved outside the drive shaft 6 and is not connected, the planetary gear 12 of the second-stage planetary gear assembly 10 drives the sun gear 13 meshed therewith to rotate. At this time, the sun gear 13 and the transmission sleeve 11 of the second-stage planetary gear assembly 10 both rotate synchronously with the drive shaft 6. Thus, the transmission sleeve 11 is not connected to the drive shaft 6 but can move synchronously. The transmission sleeve 11 and the drive shaft 6 are in a relatively static state. The adjustment wheel 2 and the swing wheel 3 also rotate with the drive shaft 6, and there is no opening and closing action between the swing arms 4. The bottom end of the driving shaft is connected to the component to be rotationally driven, and finally only the component to be rotationally driven rotates with the driving shaft 6 .

[0015] The ring gear 14 of the secondary planetary gear assembly is fixedly connected to the housing 5, the ring gear 14 of the primary planetary gear assembly is rotatably connected to the housing 5, and the ring gear 14 of the primary planetary gear assembly 8 is connected to the adjustment mechanism 7. Under normal circumstances, when the adjustment mechanism 7 is not in action, the ring gear 14 of the primary planetary gear assembly and the ring gear 14 of the secondary planetary gear assembly are both stationary on the housing 5, and only the components to be driven to rotate rotate with the drive shaft 6.

[0016] Furthermore, in order to realize the swing of the swing rod, the transmission sleeve 11 must be rotated relative to the drive shaft 6, so an adjustment mechanism 7 is provided, the adjustment mechanism 7 includes an adjustment motor 16 and an adjustment worm 17, the ring gear 14 of the first-stage planetary assembly is provided with external teeth, the adjustment worm 17 is meshed with the external teeth of the first-stage planetary assembly, and the adjustment motor 16 drives the driving end of the adjustment worm 17 to rotate. The rotation of the adjustment worm 17 can make the ring gear 14 of the first-stage planetary gear assembly rotate in the housing 5, so that the rotation speed of the planetary gear 12 of the first-stage planetary gear assembly changes, thereby changing the rotation speed of the planetary gear 12 of the second-stage planetary gear assembly, and then causing the sun gear 13 of the second-stage planetary gear assembly and the drive shaft 6 to rotate, and the static state between the transmission sleeve 11 and the drive shaft 6 changes, the adjustment wheel 2 rotates, and the swing wheel 3 rotates to make the swing arm 4 rotate, thereby realizing the opening and closing of the swing arm 4. When the adjustment worm 17 is stationary, it returns to the state where the transmission sleeve 11 and the drive shaft 6 are relatively stationary. The distance between the swing arms 4 can be adjusted while the drive shaft 6 drives the swing arms 4 to rotate.

[0017] In order to ensure the supply of lubricating oil to the drive shaft 6 , a self-lubricating pad 18 is further provided. The self-lubricating pad 18 is provided between the transmission sleeve and the drive shaft 6 .

[0018] The working process is as follows: after the component to be driven in rotation is fixedly installed together with the driving shaft, the swing arm is extended under the component to be driven in rotation, and then the brush is installed at the bottom end of the swing arm. When the driving motor 15 drives the driving shaft 6 to rotate, the component to be driven in rotation and the swing arm 4 rotate with the driving shaft 6. When the position of the brush at the bottom of the swing arm 4 needs to be adjusted, the swing angle of the swing arm 4 can be adjusted by controlling the forward and reverse rotation of the adjustment motor 16, thereby adjusting the position of the brush relative to the turntable.

[0019] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
