[0002] Welding is a technique that permanently joins metal materials by heating. It is needed in various manufacturing industries that require the combination and joining of metals. Welding can combine small pieces of metal into large pieces of metal, simplifying the casting process, thereby saving metal materials and reducing production costs. There are a wide variety of welding equipment on the market.

[0003] However, conventional welding equipment is not convenient for cleaning the parts to be welded, which may result in unclean outer surfaces that affect the welding effect. It is also not convenient for preheating before welding, which can lead to excessively rapid cooling during the weld cooling process, causing cracks at the weld position. Furthermore, it is not convenient for welding different angles of the parts, which may result in incomplete welding when the shapes of the parts are inconsistent. Therefore, we propose a rotary multi-station circulating welding equipment to solve the problems mentioned above. Utility Model Content

Detailed Implementation

[0028] 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.

[0029] Please see Figure 1-5 This utility model provides a technical solution: a rotary multi-station circulating welding device, including a base 1, a rotary body 2, a threaded rod 3, a fixed column 4, an arc plate 5, a nozzle 6, a water supply pipe 7, a water pump 8, a water tank 9, a fixed frame 10, a first motor 11, a rotating rod 12, a slider 13, an electric flame gun 14, a hydraulic rod 15, a moving frame 16, a second motor 17, a main gear 18, a connecting gear 19, and an electric welding head 20;

[0030] Existing welding equipment is not convenient for cleaning the parts to be welded, which may result in unclean outer surfaces that affect the welding effect. It is also not convenient for preheating before welding, which may lead to excessively rapid cooling of the weld during the welding process, resulting in cracks at the weld position. Furthermore, it is not convenient for welding parts at different angles, which may lead to incomplete welding when the shapes of the parts are inconsistent.

[0031] The turntable body 2 has a threaded rod 3 rotatably connected to its upper end, and an arc-shaped plate 5 is threadedly connected to the outer side of the threaded rod 3. The upper end of the arc-shaped plate 5 is slidably connected to the outer side of the fixed column 4. A nozzle 6 is installed on the inner side of the arc-shaped plate 5, and a water supply pipe 7 is fixedly connected to the outer side of the front end of the arc-shaped plate 5. A water pump 8 is fixedly connected to the upper end of the water supply pipe 7. A water tank 9 is fixedly connected to the front end of the water pump 8 through the water supply pipe 7. The lower ends of both the water pump 8 and the water tank 9 are fixedly connected to the turntable body 2, and the outer side of the lower end of the turntable body 2 is rotatably connected to the inside of the base 1.

[0032] When it is necessary to prevent excessive impurities on the outer surface of the welded parts during welding, the water pump 8 is started, and the water in the water tank 9 is pumped into the arc plate 5 through the water pipe 7. The water is then sprayed through the nozzle 6 installed on the inner side of the arc plate 5. The electric motor fixedly connected to the left end of the threaded rod 3 is started, which drives the two arc plates 5 threadedly connected to the outer side of the threaded rod 3 to move to the left or right. When the two arc plates 5 move outward, the inside of the arc plate 5 slides outward on the outside of the fixed column 4, which can clean thicker welded parts. When the two arc plates 5 move inward, the inside of the arc plate 5 slides inward on the outside of the fixed column 4, which can clean thinner welded parts. This can prevent excessive dust on the outer surface of the welded parts from affecting the welding effect.

[0033] The fixed frame 10 is fixedly connected to the turntable body 2 at its upper end, and a rotating rod 12 is rotatably connected to the front end of the fixed frame 10. The rear end of the rotating rod 12 is fixedly connected to the first motor 11. The outer rear end of the rotating rod 12 is rotatably connected to the front end of the slider 13. The slider 13 is slidably connected to the outer side of the fixed frame 10. An electric flame gun 14 is installed on the inner side of the lower end of the slider 13.

[0034] When the welding parts need to be preheated, the first motor 11 is started, which drives the rotating rod 12 fixedly connected to the front end of the first motor 11 to rotate inside the right end of the fixed frame 10. After the rotating rod 12 rotates, it pulls the slider 13 to slide left and right continuously on the outside of the fixed frame 10, and drives the electric flame gun 14 installed on the lower inner side of the slider 13 to move at the same time. This can evenly heat the welding parts and avoid the welding parts from alternating too quickly between hot and cold, which may cause the welding parts to have pores or cracks after welding.

[0035] The turntable body 2 has a movable frame 16 slidably connected to the lower end of the turntable body 2. A hydraulic rod 15 is fixedly connected to the front end of the movable frame 16. A second motor 17 is installed inside the left end of the movable frame 16. A main gear 18 is fixedly connected to the left end of the second motor 17. A connecting gear 19 is meshed with the outer side of the lower end of the main gear 18. The outer side of the right end of the connecting gear 19 and the main gear 18 are rotatably connected inside the movable frame 16. An electric welding head 20 is installed on the left end of the connecting gear 19.

[0036] As the turntable body 2 rotates continuously inside the base 1, the welded parts are cleaned and preheated before the welding process begins. When welding at different angles is required, the second motor 17 is started, driving the main gear 18 to rotate continuously. This causes the connecting gear 19, which is meshed with the lower outer side of the main gear 18, to rotate in the opposite direction. This also causes the electric welding head 20 mounted on the outer side of the connecting gear 19 to flip. When the connecting gear 19 rotates forward, the electric welding head 20 flips backward. The angle can be adjusted according to the position to be welded. The hydraulic rod 15 is then started, causing the movable frame 16, which is fixedly connected to the lower end of the hydraulic rod 15, to move up or down. This allows the movable frame 16 to slide up or down inside the lower end of the turntable body 2. The welding position can be adjusted according to the thickness of the welded parts. This system can automatically weld at different angles and perform multi-station cyclic welding, making it convenient to use.
