Detailed implementation manners

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment

[0021] Please refer to Figures 1 to 4 , which is an embodiment of the present invention. This embodiment provides a technical solution: a hub spraying clamping and rotating mechanism, including

[0022] a rotating table 1 installed inside the spraying machine base 4, and a plurality of nozzles 2 installed at the top of the spraying machine base 4 and directly above the rotating table 1. A driving motor is installed inside the spraying machine base 4 below the rotating table 1, and the output end of this driving motor penetrates to the top of the spraying machine base 4 and is connected to the rotating table 1 for driving the rotation of the rotating table 1;

[0023] A plurality of adjustable clamping mechanisms 3 arranged on the top surface of the rotary table 1, including a T-shaped sliding groove 32 opened on the surface of the rotary table 1, a T-shaped base 39 slidably installed in the T-shaped sliding groove 32, a movable seat 31 arranged on the top surface of the rotary table 1, a movable rod 33 penetrating through the top end of the movable seat 31, a movable clamping block 34 fixedly installed on the surface of one end of the movable rod 33, an anti-slip rubber pad 35 hinged and fixed on the surface of the movable clamping block 34, and an elastic movable structure arranged between the movable rod 33 and the movable seat 31. The top end of the T-shaped base 39 extends to the top surface of the rotary table 1 and is fixedly connected with the movable seat 31. Subsequently, the wheel hub can be placed between the plurality of adjustable clamping mechanisms 3 and clamped and limited by the abutment of the movable clamping block 34 and the anti-slip rubber pad 35. The elastic movable structure includes an upper sliding groove 314 opened on the upper wall of the through hole 317, a spring B315 and an upper slider 316 installed in the upper sliding groove 314. The bottom end of the upper slider 316 extends into the through hole 317 and is fixedly connected with the movable rod 33. Subsequently, when the wheel hub needs to be placed on the top of the rotary table 1, the movable rod 33 can be pulled laterally, so that the upper slider 316 is laterally displaced to compress the spring B315, and the movable clamping block 34 drives the anti-slip rubber pad 35 to be laterally displaced. Then, the wheel hub is placed inside the plurality of adjustable clamping mechanisms 3, and then the movable rod 33 is released. Under the push of the spring B315, the upper slider 316 drives the movable clamping block 34 to rebound, and finally the anti-slip rubber pad 35 abuts against the surface of the wheel hub, so that the clamping and limiting of the wheel hub can be realized through the plurality of adjustable clamping mechanisms 3.

[0024] Wherein, the adjustable clamping mechanism 3 further includes a rectangular side groove 36 opened on the side surface of the movable seat 31, a side sliding groove 311 opened on the inner wall of the rectangular side groove 36, a side slider 312 and a spring A313 installed in the side sliding groove 311, a limiting clamping rod 310 welded and fixed on the bottom surface of the side slider 312, and a plurality of limiting clamping grooves 38 opened on the inner wall of the bottom end of the T-shaped sliding groove 32. The bottom end of the limiting clamping rod 310 passes through the T-shaped base 39 and is inserted into one of the limiting clamping grooves 38 to realize the stable limiting of the T-shaped base 39 and the movable seat 31. One end of the side slider 312 extends into the rectangular side groove 36 and is fixed with a C-shaped dialing block 37, which is convenient for subsequent operators to dial the side slider 312 and the limiting clamping rod 310 through the C-shaped dialing block 37.

[0025] Among them, a cylindrical groove is formed in the inner wall at the top end of the side sliding groove 311. The top end of the spring A 313 is inserted into the cylindrical groove, which can limit the spring A 313 to prevent it from deviating. The bottom end of the spring A 313 abuts against the top surface of the side sliding block 312. Under the pushing action of the spring A 313, the bottom end of the limit clamping rod 310 can be stably inserted into the limit clamping groove 38 during daily use, ensuring the limit stability of the movable seat 31 and the T-shaped base 39. If the position of the movable seat 31 needs to be adjusted subsequently, only need to lift the C-shaped dial 37 first, so that the side sliding block 312 moves upward and compresses the spring A 313 until the bottom end of the limit clamping rod 310 moves out of the limit clamping groove 38, then the limit on the T-shaped base 39 and the movable seat 31 can be released. At this time, the movable seat 31 can be slid on the top surface of the rotating table 1 to realize the position adjustment of the movable seat 31. When the movable seat 31 is adjusted to the appropriate position, release the C-shaped dial 37, so that the spring A 313 pushes the side sliding block 312 back to its original position, then the bottom end of the limit clamping rod 310 can be inserted into the limit clamping groove 38 at other positions again, realizing the re-limitation of the T-shaped base 39 and the movable seat 31.

[0026] Among them, a through hole 317 for the movable rod 33 to pass through is formed through the top surface of the movable seat 31.

[0027] Among them, one end of the spring B 315 abuts against the side surface of the upper sliding block 316, and the other end of the spring B 315 is fixed on the inner wall of the upper sliding groove 314 to ensure the installation stability of the spring B 315.

[0028] Among them, one end of the T-shaped sliding groove 32 communicates with the circumferential surface of the rotating table 1, so that the T-shaped base 39 can be disassembled and assembled from the opening of the T-shaped sliding groove 32 subsequently.

[0029] Although the embodiments of the present invention have been shown and described (see the above detailed description), for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
