[0023] It should be noted that like numerals refer to like items throughout the several views, where like numerals can not be further defined and explained in subsequent views once defined in an initial view.

[0024] The embodiment mainly illustrates the structure of the welding device, and specifically as follows.

Figures 1-5 The welding torch 2 is installed on the mechanical arm 1, the mechanical arm 1 can rotate in multiple axes, thereby controlling the welding torch 2 to move along a spatial curve, completing welding along a complex path. The base 3 is arranged in front of the mechanical arm 1, the support frame 4 is connected to the base 3, the motor 5 is installed on the support frame 4, the rotating plate 6 is rotatably connected to the top of the support frame 4, the output shaft of the motor 5 is fixedly connected to the rotating plate 6, the fixing plates 7 are connected to the rotating plate 6, the fixing plates 7 are symmetrical along the motor 5, the number and positions of the fixing plates 7 at both ends of the rotating plate 6 are equal, the clamping assemblies 8 are arranged on the fixing plates 7, and the furnace body shell 61 is placed between the two fixing plates 7.

[0026] As shown in Figure 3 and Figure 5 , the clamping assembly 8 comprises guide rods 81, clamping plates 82 and return springs 83. Two guide rods 81 are slidably connected to each fixing plate 7, the end of the guide rod 81 is connected to the clamping plate 82, each two fixing plates 7 are matched, the clamping plates 82 connected to the two fixing plates 7 are close to each other, the clamping plate 82 is in contact with the furnace body shell 61, the return spring 83 is sleeved on the guide rod 81, one end of the return spring 83 is connected to the clamping plate 82, and the other end of the return spring 83 is connected to the fixing plate 7. The return spring 83 pushes the clamping plate 82 to clamp the furnace body shell 61.

[0027] The worker places the iron plate to be welded on the rotating plate 6 and in the clamping assembly 8, thereby clamping and fixing the spliced iron plate, improving the fixing efficiency of the iron plate. Then the motor 5 is started to drive the rotating plate 6 to rotate by 180 degrees, so that the furnace body shell 61 is close to the mechanical arm 1. The mechanical arm 1 controls the welding torch 2 to move according to the set welding program and moves along the specified welding line, thereby completing the welding of the furnace body shell 61. Then the motor 5 continues to control the rotating plate 6 to rotate by 180 degrees. When the mechanical arm 1 is working, one end of the rotating plate 6 is away from the mechanical arm 1. At this time, the worker also fixes the furnace body shell 61 to be welded on the rotating plate 6. When the previous furnace body shell 61 is replaced after welding, the rotating plate 6 rotates, and the mechanical arm 1 immediately welds the next furnace body shell 61. After the worker takes down the welded furnace body shell 61, the worker clamps the furnace body shell 61 to be welded. In this way, the work efficiency is improved.

[0028] When the furnace shell 61 is put in, the furnace shell 61 extrudes the clamping plate 82, the clamping plate 82 moves to both sides, the guide rod 81 connected with the clamping plate 82 slides on the fixed plate 7, the clamping plate 82 compresses the reset spring 83 during the movement, and a plurality of fixed plates 7 clamp and fix the furnace shell 61, so as to ensure the stability of welding. After the welding is completed, the workers take out the furnace shell 61 upwards, the reset spring 83 rebounds, and the clamping plate 82 and the guide rod 81 slide and reset.

[0029] As shown in Figure 4 , it also includes a wedge-shaped ring frame 9, a top rod 10, a connecting block 11, a buffer spring 12 and an auxiliary wheel 14. The wedge-shaped ring frame 9 is connected to the side of the base 3, the top of the wedge-shaped ring frame 9 is inclined, and the side away from the mechanical arm 1 is higher. The wedge-shaped ring frame 9 is arc-shaped as a whole and coincides with the movement path of the auxiliary wheel 14. The rotary plate 6 is slidingly connected with the top rod 10. The top of the top rod 10 is in extrusion fit with the furnace shell 61. The bottom of the top rod 10 is connected with the connecting block 11. The bottom of the connecting block 11 is rotatably connected with the auxiliary wheel 14. The auxiliary wheel 14 is rollingly connected with the wedge-shaped ring frame 9. The top rod 10 is lifted by the auxiliary wheel 14. The top rod 10 lifts the furnace shell 61. The buffer spring 12 is sleeved on the top rod 10. The top of the buffer spring 12 is connected with the rotary plate 6. The bottom of the buffer spring 12 is connected with the connecting block 11.

[0030] During the rotation of the rotary plate 6, the auxiliary wheel 14 contacts the top surface of the wedge-shaped ring frame 9. During the rotation of the rotary plate 6, the auxiliary wheel 14 rotates along the inclined surface of the wedge-shaped ring frame 9, gradually lifting the top rod 10. The top rod 10 slides upward in the rotary plate 6. The top of the top rod 10 lifts the furnace shell 61, thereby completing automatic discharging without manual taking. The buffer spring 12 is compressed during the upward movement of the top rod 10. The furnace shell 61 is directly taken by the worker after being lifted. After the auxiliary wheel 14 is separated from the wedge-shaped ring frame 9, the buffer spring 12 rebounds, pushing the top rod 10 to slide downward and reset. At the same time, the connecting block 11 and the auxiliary wheel 14 are also reset, which is convenient for placing the furnace shell 61 to be welded.

[0031] As shown in Figure 5 , it also includes a roller 13. The side of the clamping plate 82, which is not connected with the guide rod 81, is rotatably connected with the roller 13. The outer ring of the roller 13 is made of rubber, which can optimize the process of putting in and taking out the furnace shell 61 and better clamp the furnace shell 61 during welding, thereby optimizing the stability of the welding process of the furnace shell 61.

[0032] As shown in Figure 4 , it also includes a sponge pad 15. The top of the top rod 10 is connected with the sponge pad 15. The sponge pad 15 contacts the furnace shell 61, thereby buffering the impact force of the top rod 10 and protecting the furnace shell 61.

[0033] AsFigure 4 As shown, it also includes the ball 16, support frame 4 top rotary connection with several ball 16, ball 16 top protruding support frame 4 and contact with the rotating plate 6, rotating plate 6 in rotation, through the ball 16 can reduce friction, so as to optimize the position of the rotating plate 6 transformation.

[0034] As shown, Figure 1 As shown, it also includes the protective cover 17, mechanical arm 1 outside the protective cover 17 is provided, the staff to block, prevent the staff close to the welding torch 2 work area, but also can protect the working environment of the mechanical arm 1.

[0035] As shown, Figure 2 As shown, it also includes the light 18, protective cover 17 is installed with the light 18, when the maintenance or cleaning to provide light, so as to facilitate the staff to carry on the corresponding work.

[0036] The furnace shell 61 is placed on the rotating plate 6, and the furnace shell 61 is clamped and fixed under the action of the guide rod 81 and the return spring 83 through the clamping plate 82 in the clamping assembly 8. The rotating roller 13 on the clamping plate 82 not only optimizes the placing and taking process of the furnace shell 61, but also enhances the stability during welding. Subsequently, the motor 5 is started, driving the rotating plate 6 to rotate 180 degrees, so that the furnace shell 61 is close to the mechanical arm 1. The mechanical arm 1 controls the welding torch 2 to move according to the preset welding program, and completes the welding of the complex path. In the welding process, the protective cover 17 effectively blocks the staff from approaching the working area of the welding torch 2, ensuring safety. At the same time, the light 18 in the protective cover 17 provides sufficient light for maintenance or cleaning. After completing the welding on one side, the motor 5 drives the rotating plate 6 to rotate 180 degrees again, so that the welded furnace shell 61 is away from the mechanical arm 1, facilitating the staff to take out, and the staff can fix the furnace shell 61 to be welded on the other side of the rotating plate 6, realizing continuous operation and improving efficiency. In the rotating process of the rotating plate 6, the auxiliary wheel 14 rolls along the inclined surface of the wedge-shaped ring frame 9, the connecting block 11 lifts the jacking rod 10, and the sponge pad 15 on the jacking rod 10 buffers and lifts the furnace shell 61, realizing automatic discharge. When the jacking rod 10 rises, the buffer spring 12 is compressed, and after the jacking rod 10 is separated from the wedge-shaped ring frame 9, the buffer spring 12 rebounds, and the jacking rod 10 resets. In addition, the ball 16 on the top of the support frame 4 reduces the friction when the rotating plate 6 rotates, ensuring smooth rotation.
