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.

[0022] The present utility model provides as Figures 1 to 4An outer surface polishing device for producing a kettle body is shown, including a base 1. A rotating motor 2 is fixed at the bottom of the base 1. The output shaft of the rotating motor 2 penetrates into the inner cavity of the base 1 and is fixed with a rotating seat 3. The top of the rotating seat 3 is provided with a kettle body. Inside the inner cavity of the rotating seat 3, a first movable frame 4 and a second movable frame 5 are respectively movably arranged. The tops of the first movable frame 4 and the second movable frame 5 penetrate through the rotating seat 3 and extend into the interior of the kettle body. Inside the first movable frame 4 and the second movable frame 5, a first screw rod 6 and a second screw rod 7 that rotate in the inner cavity of the rotating seat 3 through bearings are respectively threadedly connected through a threaded sleeve. A driving component 8 for driving the first screw rod 6 and the second screw rod 7 is arranged in the inner cavity of the rotating seat 3. A fixing frame 9 is fixed at the top of the rotating seat 3. Two groups of rotating shafts 10 are rotatably connected to the inner side of the fixing frame 9 through bearings. A side pressing plate 11 is fixed on the surface of the rotating shaft 10. A first electric push rod 12 is fixedly installed at the top of the fixing frame 9. The piston rod of the first electric push rod 12 penetrates into the inner cavity of the fixing frame 9 and is fixed with a pressing plate 13;

[0023] The driving component 8 drives the first screw rod 6 and the second screw rod 7 to rotate, and the screw sleeve drives the first movable frame 4 and the second movable frame 5 to move relatively, so as to support and limit the kettle body from the inside. At the same time, the first electric push rod 12 squeezes the side pressing plate 11 to expand outwards through the pressing plate 13, squeezes and fits the inside of the kettle body mouth, and stably limits the kettle body on the top of the rotating seat 3, which is convenient for polishing the outer side of the kettle body and avoids that it is impossible to polish the whole outer part of the kettle body in one time when fixing the kettle body from the outside.

[0024] The driving component 8 includes a driving motor 81 fixed on one side of the inner cavity of the rotating seat 3. The output shaft of the driving motor 81 is fixedly connected to one end of the first screw rod 6. A driving gear 82 is fixed on the surface of the first screw rod 6. Driven gears 83 meshing with the driving gear 82 are fixed on the surfaces of the two groups of second screw rods 7. The driving motor 81 drives the first screw rod 6 to rotate, and then the first screw rod 6 drives the two groups of second screw rods 7 on both sides to rotate through the driving gear 82 and the driven gears 83, and then the first movable frame 4 and the second movable frame 5 are driven to move relatively through the screw sleeve, which is convenient for telescopic adjustment of the first movable frame 4 and the second movable frame 5 and convenient for supporting and clamping the kettle body.

[0025] Grooves 14 are formed on the opposite sides of the side pressing plate 11. The pressing plate 13 is located inside the grooves 14. Through the setting of the grooves 14, it is convenient for the pressing plate 13 to be stored, and at the same time, the side pressing plate 11 is squeezed during the downward movement of the pressing plate 13, so that the side pressing plate 11 expands outwards.

[0026] It further includes a mounting bracket 15 fixed to the side of the base 1. A second electric push rod 16 is fixed to the side of the mounting bracket 15. The piston rod of the second electric push rod 16 penetrates through the mounting bracket 15 and is fixed with a polishing plate 17. The second electric push rod 16 drives the polishing plate 17 to approach the kettle body. The side wall of the kettle body is polished by the polishing plate 17. If it is necessary to polish the bottom of the kettle body, a set of polishing discs can be arranged above to polish the bottom of the kettle body.

[0027] Both ends of the rotating shaft 10 are fixed with torsion springs 18. The end of the torsion spring 18 away from the rotating shaft 10 is fixed to the inner wall of the fixing bracket 9. Through the setting of the torsion spring 18, it is convenient for the side pressing plate 11 to automatically fold upward under the elastic potential energy of the torsion spring 18 after the first electric push rod 12 drives the pressing plate 13 to move upward.

[0028] A limiting rod 19 is fixed to the surface of the polishing plate 17. The end of the limiting rod 19 away from the polishing plate 17 penetrates through the mounting bracket 15 and extends outward. Through the setting of the limiting rod 19, it is convenient to limit the polishing plate 17 and prevent the polishing plate 17 from deflecting under the drive of the rotating kettle body, affecting the polishing effect on the outer side of the kettle body.

[0029] A boss that is snap-fitted with the kettle mouth of the kettle body is integrally formed on the top of the rotating base 3. The sizes of the first movable frame 4, the second movable frame 5 and the side pressing plate 11 after contraction are smaller than the size of the kettle mouth of the kettle body. Through the setting of the boss, it is convenient to position the kettle body from the position of the kettle mouth of the kettle body to ensure stable clamping of the kettle body.

[0030] During specific use, the kettle body is sleeved outside the first movable frame 4 and the second movable frame 5 from above. At the same time, the kettle mouth position of the kettle body is snap-fitted with the boss. The drive motor 81 is started. The drive motor 81 drives the first screw rod 6 and the drive gear 82 to rotate. Then the drive gear 82 drives two groups of second screw rods 7 to rotate through the driven gear 83. At this time, the first screw rod 6 and the second screw rod 7 respectively translate the first movable frame 4 and the second movable frame 5 by using the screw sleeves, so that the first movable frame 4 and the second movable frame 5 support and fix the kettle body inside the kettle body. At the same time, the first electric push rod 12 on the fixing bracket 9 drives the pressing plate 13 to move downward. The pressing plate 13 squeezes the side pressing plate 11 through the groove 14, so that the side pressing plate 11 expands outward. Then the side pressing plate 11 is flattened to squeeze and limit the inside of the kettle mouth of the kettle body, so that the kettle body is restricted on the top of the rotating base 3. Then the rotating motor 2 is started to drive the rotating base 3 to rotate in the base 1. At the same time, the kettle body rotates together with the rotating base 3. The second electric push rod 16 drives the polishing plate 17 to approach the kettle body, and then polishes the outer side wall of the kettle body.
