DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figures 1-3 , a thermal spraying device for a valve sphere, comprising:

[0021] A workbench 1, a fixed bracket 2 is fixedly connected to the top end of the workbench 1, and a fixed spray head 3 is fixedly connected to one side wall of the fixed bracket 2. The valve sphere is sprayed through the fixed spray head 3;

[0022] A fixing structure, including a connecting plate 11 installed on one side of the fixed spray head 3. An installation rod 12 is slidably connected to the top end of the connecting plate 11. A sliding block 13 is fixedly connected to the bottom end of each installation rod 12. A sliding groove 14 corresponding to the sliding block 13 is opened on the top end of the connecting plate 11. A connecting shaft 15 is rotatably connected between the inner walls of the sliding groove 14. Each sliding block 13 is threadedly sleeved on the outside of the connecting shaft 15, and the threads on both sides of the sliding block 13 are arranged in opposite directions. The installation rod 12 is extended into the valve hole of the valve sphere, and the connecting shaft 15 is rotated. Since the sliding block 13 cannot rotate, under the action of the thread, the sliding block 13 will move, thereby driving the installation rod 12 to move together, so that the installation rod 12 abuts against the inner wall of the valve hole of the valve sphere, and the valve sphere is fixed to facilitate spraying;

[0023] A motor 4 is fixedly connected to the top end of the workbench 1. The output end of the motor 4 is fixedly connected to a rotating rod 6. A fixed rod 7 is slidably connected to the rotating rod 6. The top end of the fixed rod 7 is fixedly connected to the bottom end of the connecting plate 11. An adjusting sleeve 9 is slidably sleeved on the fixed rod 7. A reciprocating lead screw groove is arranged inside the adjusting sleeve 9. The adjusting sleeve 9 is slidably connected to the fixed rod 7 through the reciprocating lead screw groove. One side of the adjusting sleeve 9 is fixedly connected to an installation bracket 8. The motor 4 is started, and the output end of the motor 4 drives the rotating rod 6 to rotate, so that the connecting plate 11 of the fixed rod 7 moves accordingly, and the valve sphere rotates together, so that the entire valve sphere can be sprayed by the fixed spray head 3. At the same time, since the adjusting sleeve 9 cannot rotate, during the rotation of the fixed rod 7, the fixed rod 7 will move up and down due to the action of the reciprocating lead screw groove, driving the connecting plate 11 and the valve sphere to move up and down together, so that the fixed spray head 3 can spray the top end of the valve sphere and the outside of the bottom valve hole, making the spraying more complete;

[0024] A protective housing 5 is wrapped outside the motor 4. The bottom end of the protective housing 5 is fixedly connected to the workbench 1, and the protective housing 5 is penetrated by the rotating rod 6. The bottom end of the installation bracket 8 is fixedly connected to the top end of the protective housing 5. The protective housing 5 plays a role in protecting the motor 4;

[0025] The bottom end of the fixed rod 7 penetrates through the inner side wall of the rotating rod 6 and extends to the inner side of the rotating rod 6. A fixed spring 10 is fixedly connected to the bottom end of the fixed rod 7, and the end of the fixed spring 10 away from the fixed rod 7 is fixedly connected to the lower inner wall of the rotating rod 6. The elastic force of the fixed spring 10 supports the fixed rod 7 and can also buffer during the up and down movement of the fixed rod 7.

[0026] One end of the connecting shaft 15 penetrates through the inner side wall of the sliding groove 14 and extends to the outside of the connecting plate 11. A rotating block 16 is fixedly connected to the end of the connecting shaft 15 located outside the connecting plate 11, and anti-slip lines are provided on the side wall of the rotating block 16. Rotating the rotating block 16 can make the connecting shaft 15 rotate; Rounding corners are provided on the side wall of each mounting rod 12 near the outside, so that after the mounting rod 12 extends to the valve hole of the spherical valve, the side wall of the valve hole can be resisted.

[0027] In the present utility model, when the device is in use, first extend the mounting rod 12 into the valve hole of the valve sphere. Rotating the rotating block 16 can make the connecting shaft 15 rotate. Since the sliding block 13 cannot rotate, under the action of the thread, the sliding block 13 will move, thereby driving the mounting rod 12 to move together, so that the mounting rod 12 resists the inner wall of the valve hole of the valve sphere and fixes the valve sphere, facilitating the spraying. At the same time, start the fixed nozzle 3 and the motor 4. The fixed nozzle 3 sprays the valve sphere. After the motor 4 is started, the output end of the motor 4 drives the rotating rod 6 to rotate, so that the connecting plate 11 of the fixed rod 7 moves accordingly, and the valve sphere rotates together, so that the entire valve sphere can be sprayed by the fixed nozzle 3. At the same time, since the adjusting sleeve 9 cannot rotate, during the rotation of the fixed rod 7, the fixed rod 7 will move up and down due to the action of the reciprocating screw groove, driving the connecting plate 11 and the valve sphere to move up and down together, so that the fixed nozzle 3 can spray the top end of the valve sphere and the outside of the bottom valve hole, making the spraying more complete.

[0028] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
