[0010] Preferably, a slider is fixedly connected to the outer wall of the top plate, and multiple sliders are distributed in a circular pattern at equal intervals about the outer wall of the top plate.

[0011] Preferably, the inner wall of the inner housing has a slot, and a slider is inserted into the slot, forming a sliding connection with the inner housing.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) This device can partially isolate the heat generated during the working process, thereby reducing the impact of temperature on the worker's body when the worker is in close proximity to the device for a long time, and improving the safety of the welding process.

[0014] (2) This device sets an outer shell on the outer wall of the inner shell, fixes a third electric cylinder on the inner wall of the outer shell, and inserts a protective cover between the inner shell and the outer shell, so that the third electric cylinder can push the protective cover to rise and fall automatically.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4This utility model provides a technical solution: a horizontally rotatable welding platform structure, including an inner shell 7, a top plate 10 inserted into the inner wall of the inner shell 7, and sliders 16 fixedly connected to the outer wall of the top plate 10. Multiple sliders 16 are distributed in a circular, evenly spaced manner around the outer wall of the top plate 10. This structure, by setting multiple sliders 16, makes the top plate 10 more stable when moving. A slot is formed on the inner wall of the inner shell 7, and the sliders 16 are inserted into the slot, forming a sliding connection with the inner shell 7. This structure, by setting sliders 16, improves the stability of the inner top plate 10 when descending, ensuring the accuracy of the insertion of the top plate 10 into the inner shell 7. A drive motor 8 is installed at the bottom of the top plate 10, and second electric cylinders 9 are set on both sides of the drive motor 8. The top of the second electric cylinders 9... Connected to the top plate 10, a turntable 6 is rotatably connected to the top of the top plate 10. A first electric cylinder 5 is fixedly connected to the top of the turntable 6. One end of the first electric cylinder 5 is connected to the mounting frame 1. The mounting frame 1 and the turntable 6 form a sliding connection. This structure allows the mounting frame 1 to move laterally left and right via the first electric cylinder 5, thereby facilitating the position adjustment of the fixed plate 2 and the upper chuck 3 on the mounting frame 1. A groove is provided on the inner side of the mounting frame 1, and a first reciprocating ball screw mechanism 14 is installed inside the groove. The first reciprocating ball screw mechanism 14 is symmetrically distributed front and back about the bisector of the mounting frame 1. This structure can ensure the stability of both ends when the second reciprocating ball screw mechanism 15 moves inside the first reciprocating ball screw mechanism 14. The second reciprocating ball screw is connected to the inner side of the first reciprocating ball screw mechanism 14. Mechanism 15, the second reciprocating ball screw mechanism 15, has a fixed plate 2 fixedly connected to one side. The first reciprocating ball screw mechanism 14 and the second reciprocating ball screw mechanism 15 have the same structure, both consisting of a motor, a fixed seat, a threaded rod, and a screw slide. The inner wall of the screw slide of the second reciprocating ball screw mechanism 15 is fixedly connected to the fixed plate 2, and the inner wall of the screw slide of the first reciprocating ball screw mechanism 14 is connected to the fixed seats at both ends of the second reciprocating ball screw mechanism 15. The second reciprocating ball screw mechanism 15 can drive the fixed plate 2 to move vertically, and the first reciprocating ball screw mechanism 14 can drive the second reciprocating ball screw mechanism 15 and the fixed plate 2 to move back and forth, thereby facilitating the adjustment of the position of the upper chuck 3. A lower... A mounting bracket 1 is connected to the top side of the chuck 4 and turntable 6. A fixing plate 2 is slidably connected to the top side of the mounting bracket 1. An upper chuck 3 is installed at the bottom of the fixing plate 2. The upper chuck 3 and lower chuck 4 are positioned correspondingly and are used to clamp the product. Both the upper chuck 3 and lower chuck 4 are existing technologies and will not be described in detail here. An outer shell 12 is fitted onto the outer wall of the inner shell 7. Both the outer shell 12 and the protective cover 11 are annular structures. The protective cover 11 is slidably connected to the outer shell 12 and the inner shell 7. The protective cover 11 is made of high-temperature resistant vacuum glass. The protective cover 11 not only facilitates observation of the welding process but also isolates some of the heat generated during welding. The protective cover 11 is inserted between the outer shell 12 and the inner shell 7. A third electric cylinder 13 is connected to the bottom of the protective cover 11.The outer wall of the third electric cylinder 13 is bolted to the inside of the outer casing 12. The third electric cylinder 13 can automatically raise and lower the protective cover 11. The inner diameter of the protective cover 11 is larger than the width and length of the turntable 6, ensuring smooth raising and lowering of the protective cover 11 and protecting the turntable 6.

[0023] Working principle: When using this horizontally rotatable welding platform structure, the two products to be welded are first clamped and fixed inside the upper chuck 3 and lower chuck 4 respectively. After clamping the two products, the position of the upper chuck 3 is adjusted. During the adjustment process, the first electric cylinder 5 pushes the mounting frame 1 to move the position of the upper chuck 3 laterally. The first reciprocating ball screw mechanism 14 inside the mounting frame 1 drives the upper chuck 3 to rise and fall, and the second reciprocating ball screw mechanism 15 drives the position of the upper chuck 3 to move back and forth, so that the products on the upper chuck 3 and the products on the lower chuck 4 can be accurately spliced. Before welding, the welding height of the turntable 6 can also be adjusted. During adjustment, the second electric cylinder 9 pushes the top plate 10 to rise and fall inside the inner shell 7, so that the turntable 6 is at a suitable height. During welding, the third electric cylinder 13 pushes the protective cover 11 to rise, so that the protective cover 11 encloses and isolates the turntable 6, thereby avoiding the temperature during the welding process from affecting the workers.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
