The servo motor 5 is connected to an external power supply and is provided with a power control switch. The output end of the servo motor 5 is fixedly connected to an adjusting screw rod 6. One end of the adjusting screw rod 6 sequentially penetrates through the first chassis 4, the turntable 2 and extends into the installation groove inside the bottom of the turntable 2. A transmission seat 7 is sleeved on the rod surface of the adjusting screw rod 6 and located inside the installation groove. A limiting block 10 is fixedly connected to the bottom of the transmission seat 7 and at the bottom end of the adjusting screw rod 6. A gear drive assembly 9 is sleeved outside the turntable 2 and on one side of the top of the installation frame 1. Six moving holes 3 communicating with the installation groove are evenly formed outside the turntable 2 around the axis of the adjusting screw rod 6. Six adjusting hanging parts 8 are evenly fixedly connected to the outer surface of the transmission seat 7 around the axis of the adjusting screw rod 6. One end of each of the six adjusting hanging parts 8 away from each other penetrates through the turntable 2 through the moving hole 3 and extends to the outside of the turntable 2.

[0026] Please refer to Figures 2-5 , the turntable 2 is rotatably connected to the installation frame 1, the adjusting screw rod 6 is rotatably connected to the first chassis 4, the adjusting screw rod 6 is rotatably connected to the turntable 2, the adjusting screw rod 6 is threadedly connected to the transmission seat 7. The adjusting screw rod 6 is limited by the six adjusting hanging parts 8 and the moving holes 3. When the adjusting screw rod 6 rotates clockwise, the transmission seat 7 can be driven to move upward. When the adjusting screw rod 6 rotates counterclockwise, the transmission seat 7 can be driven to move downward. The top of the limiting block 10 is in contact with the bottom of the transmission seat 7, and the limiting block 10 has a limiting effect on the transmission seat 7.

[0027] Please refer to Figures 3-5, the adjusting hanging part 8 includes two fixing blocks 81, both of the two fixing blocks 81 are fixedly connected to one side of the transmission seat 7, a connecting block 82 is hinged between the opposite sides of the two fixing blocks 81 through a pin shaft, a limiting telescopic rod 83 is fixedly connected to the side of the connecting block 82 away from the transmission seat 7, a hanging rod 84 is fixedly connected to the end of the limiting telescopic rod 83 away from the transmission seat 7, one end of the hanging rod 84 passes through the turntable 2 through a movable hole 3 and extends to the outside of the turntable 2, a mounting shaft 85 penetrates between the two sides of the hanging rod 84 and between the two sides of the inner wall of the movable hole 3, an anti-slip rubber sleeve 86 is sleeved on the rod surface of the hanging rod 84 and located outside the turntable 2, the mounting shaft 85 is rotatably connected to the hanging rod 84, the mounting shaft 85 is fixedly connected to the movable hole 3, the hanging rod 84 rotates up and down inside the movable hole 3 through the mounting shaft 85, and the anti-slip rubber sleeve 86 can increase the friction when the hanging rod 84 hangs the shaft seal seat, so that when the turntable 2 rotates, the shaft seal seat hung on the hanging rod 84 will not be thrown out from the hanging rod 84 due to centrifugal force. The two ends of the anti-slip rubber sleeve 86 are in the shape of inverted round corners. When the end of the hanging rod 84 away from the transmission seat 7 moves downward to make the hanging rod 84 inclined, the shaft seal seat hung on the hanging rod 84 through the anti-slip rubber sleeve 86 can slide downward.

[0028] Please refer to Figures 1-3 , the gear drive assembly 9 includes an external gear ring 91 and a second chassis 92. The external gear ring 91 is sleeved outside the turntable 2 and is located directly above the mounting frame 1. The second chassis 92 is fixedly connected to the other side of the top of the mounting frame 1. A drive motor 93 is fixedly connected inside the second chassis 92. The drive motor 93 is connected to an external power supply and is provided with a power control switch. The output end of the drive motor 93 is fixedly connected to a driving shaft 94. One end of the driving shaft 94 penetrates through the second chassis 92 and extends to the outside of the second chassis 92. A driving wheel 95 is fixedly connected to one end of the driving shaft 94 and located at the bottom of the external gear ring 91. The teeth on both the driving wheel 95 and the external gear ring 91 are conical. The driving wheel 95 meshes with the external gear ring 91. The external gear ring 91 is fixedly connected to the turntable 2, and the driving shaft 94 is rotatably connected to the second chassis 92.

[0029] Specific implementation method: By sequentially hanging the unsprayed and processed shaft seal seats on the hanging rods 84 inside the six adjusting hanging parts 8, starting the drive motor 93 inside the gear drive assembly 9, the drive motor 93 drives the driving wheel 95 to rotate through the driving shaft 94, and the driving wheel 95 drives the external gear ring 91 to rotate, so as to drive the turntable 2 to rotate on the mounting frame 1, and thus can drive the six adjusting hanging parts 8 with shaft seal seats hung thereon to perform circular motion, and then can uniformly rotate and spray-process the multiple hung shaft seal seats. The anti-slip rubber sleeve 86 can increase the friction when the hanging rod 84 hangs the shaft seal seat, so that when the turntable 2 rotates, the shaft seal seat hung on the hanging rod 84 will not be thrown out from the hanging rod 84 due to centrifugal force.

[0030] After the spraying process is completed, start the clockwise rotation switch at the output end of the servo motor 5, which can then drive the adjusting screw rod 6 to rotate clockwise. Since the adjusting screw rod 6 is limited between the six adjusting hanging parts 8 and the movable hole 3, when the adjusting screw rod 6 rotates clockwise, it can drive the transmission seat 7 to move upward. While the transmission seat 7 moves upward, it can drive one end of the fixed block 81, the connecting block 82, and the limit telescopic rod 83 inside the six adjusting hanging parts 8 to move upward, causing the limit telescopic rod 83 to stretch while tilting. The limit telescopic rod 83 drives the hanging rod 84 to rotate and tilt inside the movable hole 3, so that the shaft seal seat hung on the surface of the hanging rod 84 can slide downwards, and the shaft seal seat hung on the spraying fixture can be quickly unloaded. The two ends of the anti-slip rubber sleeve 86 are in the shape of inverted round corners, so that the resistance can be reduced during the downward sliding of the shaft seal seat hung on the hanging rod 84 through the anti-slip rubber sleeve 86.

[0031] When the adjusting screw rod 6 rotates counterclockwise, it can drive the transmission seat 7 to move downward. The top of the limit block 10 contacts the bottom of the transmission seat 7, and the limit block 10 has a limiting effect on the transmission seat 7, so that the hanging rod 84 inside the six adjusting hanging parts 8 can be reset and rotated, and the shaft seal seat spraying process can continue.

[0032] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
