[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a core rotary flow coating fixture, which includes a fixed frame 1. One side of the fixed frame 1 is rotatably connected to a mounting plate 2 through a rotating shaft 3. One end of the fixed frame 1 is fixedly connected to a rotary cylinder 4. One end of the rotary cylinder 4 is fixedly connected to a connecting block 5. One end of the connecting block 5 is fixedly connected to the rotating shaft 3. A front and rear clamping mechanism 6 is arranged at the upper end of the mounting plate 2. A left and right clamping mechanism 7 is arranged on one side of the mounting plate 2. The front and rear clamping mechanism 6 and the left and right clamping mechanism 7 clamp and fixedly connect a core body 8. A positioning column 15 is fixedly connected to one side of the mounting plate 2. A jacking cylinder 16 is fixedly connected to the back of the mounting plate 2.
[0018] In this implementation scheme, the positioning column 15 and the jacking cylinder 16 arranged play a certain positioning role, enabling the core body 8 to be positioned and installed. At this time, the front and rear clamping mechanism 6 and the left and right clamping mechanism 7 arranged at the upper end and one side can clamp and fix the core body 8 to a certain extent. When coating after fixing, the rotary cylinder 4 can be telescoped to drive the connecting block 5 to rotate, which can drive the mounting plate 2 to rotate, and then drive the core body 8 to rotate for coating, making the coating on the surface of the core body 8 more uniform. This design method can drive the core body 8 to rotate for coating after playing the role of fixing and clamping. During the rotation process, the coating can be more evenly covered on the surface of the core body 8, making the coating more uniform.

One side of the front and rear clamping plates 9 is fixedly connected to a first telescopic cylinder 11. The first telescopic cylinder 11 is fixedly connected to the back of the mounting plate 2.
[0020] In this embodiment, the first limit sliding column 10 arranged can limit the front and rear clamping plates 9 to a certain extent. When the first telescopic cylinder 11 is telescoped, it can drive the front and rear clamping plates 9 to move up and down for clamping.
[0021] Specifically, the left and right clamping mechanism 7 includes left and right clamping plates 12 and a second telescopic cylinder 14. A second limit sliding column 13 is fixedly connected to one side of the back of the mounting plate 2. One end of the left and right clamping plates 12 is slidably sleeved on the surface of the second limit sliding column 13. The second telescopic cylinder 14 is fixedly connected to the back of the mounting plate 2. One end of the second telescopic cylinder 14 is fixedly connected to the left and right clamping plates 12.
[0022] In this embodiment, the second telescopic cylinder 14 arranged can be telescoped to drive the left and right clamping plates 12 to clamp the core body 8, so as to cooperate with the front and rear clamping plates 9 to fix the core body 8 well.
[0023] Specifically, a fixing ring 17 is fixedly connected to the back surface of the fixing frame 1, and a guardrail 18 is fixedly connected to the surface of the fixing frame 1.
[0024] In this embodiment, the overall fixing is facilitated by the provided fixing ring 17, and certain protection can be achieved through the provided guardrail 18.
