Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 3 and Figure 4 , the utility model provides an embodiment: a welding device for processing a steel fire door, comprising a processing table 1, the front and rear ends of the right side of the processing table 1 are fixedly connected with a fixing block 26, the middle of the two fixing blocks 26 is rotatably connected with a support plate 2, the left and right ends of the top of the support plate 2 are fixedly connected with a mounting cover 4, the inside of the two mounting covers 4 are rotatably connected with a first threaded rod 11, the outer side of the first threaded rod 11 is threadedly connected with two first threaded blocks 15, the outside of the two first threaded blocks 15 are rotatably connected with a connecting rod 12, the other end of the connecting rod 12 is fixedly connected with a clamping plate 5, the outside of one mounting cover 4 is fixedly connected with a first motor 3, the output end of the first motor 3 is fixedly connected to one end of the first threaded rod 11, the front and rear ends of the top of the processing table 1 are provided with a slide groove 20, the outside of the processing table 1 is fixedly connected with a second motor 6, the output end of the second motor 6 is fixedly connected with a second threaded rod 21, the outer side of the second threaded rod 21 is threadedly connected with a second threaded block 22, the rear end of the processing table 1 is installed with a smoke removal component, and the rear side of the processing table 1 is installed with a welding component.

[0025] Specifically, the fixing block 26 is connected with the support plate 2 by rotation, and the fixing block 26 supports the support plate 2. The first motor 3 is fixed by the mounting cover 4, so that the first motor 3 drives the first threaded rod 11 to rotate after starting, and then pushes the two first threaded blocks 15 to approach each other, so that the clamping plate 5 is pushed to slide on the surface of the support plate 2 under the support of the connecting rod 12. At the same time, the first threaded rod 11 drives the first synchronous wheel 13 to rotate, and then the second synchronous wheel 14 is rotated through the belt, thereby driving the other first threaded rod 11 to rotate, and then achieving the same effect on the other clamping plate 5, so that the two clamping plates 5 are close to each other, thereby realizing the clamping operation of the fire door, so that the steel fire door can be welded. No movement will be generated, thereby affecting the welding effect. The second motor 6 drives the second threaded rod 21 to rotate, thereby causing the second threaded block 22 to move along the inner wall of the slide groove 20, thereby pushing the support rod 25 to move, causing its angle to change. At the same time, the slider 24 slides along the slide groove 20, thereby causing the angle of the other support rod 25 to change. With the support of the two support rods 25 on the support plate 2, the angle of the support plate 2 can be adjusted, which is convenient for workers to adjust the welding position without moving the position of the fire door, saving time and effort. The smoke generated during welding is absorbed by the smoke removal component, thereby reducing pollution to the environment and harm to the human body. The fire door is welded by the welding component, thereby realizing the processing operation of the fire door.

[0026] Reference Figure 2 The smoke removal component includes a filter box 16, which is fixedly connected to the rear end of the processing table 1, and the outside of the filter box 16 is fixedly connected to a connecting pipe 19, and the other end of the connecting pipe 19 is fixedly connected to an air suction hood 7, and the outside of the filter box 16 is fixedly connected to an exhaust fan 17, and the outside of the exhaust fan 17 is fixedly connected to a water tank 18, and the outside of the air suction hood 7 is fixedly connected to the outside of the support frame 8. The inside of the filter box 16 is installed with a filter screen and an activated carbon plate.

[0027] Specifically, by starting the exhaust fan 17 and generating the airflow, the gas generated during welding and collected through the suction hood 7 can enter the connecting pipe 19, and then be transported through the connecting pipe 19 into the filter box 16. After being processed by the filter box 16, it is transmitted to the water tank 18 to complete the absorption of the residual harmful gas, thereby realizing the operation of processing and absorbing the harmful fumes generated by welding, reducing the pollution to the environment and the harm to the workers' bodies. The filter net installed in the filter box 16 can filter some larger dust and extend the service life of the device. The activated carbon plate can adsorb harmful gases and reduce the emission of harmful gases.

[0028] Reference Figure 2The welding assembly includes a support frame 8, an electric slide rail is installed at the rear end of the processing table 1, the support frame 8 is slidably connected to the outside of the electric slide rail, a cylinder 9 is fixedly connected to the top of the support frame 8, and a welding gun 10 is fixedly connected to the output end of the cylinder 9.

[0029] Specifically, the support frame 8 is moved by the electric slide rail to adjust the welding device to the position where welding is required, and the welding gun 10 is pushed to move by the cylinder 9 to complete the welding, wherein the support frame 8 supports the cylinder 9.

[0030] Reference Figure 4 A slide rod 23 is fixedly connected to the inside of another slide groove 20, and a slider 24 is slidably connected to the outside of the slide rod 23. The slider 24 and the outside of the second threaded block 22 are rotatably connected to a support rod 25. One end of the support rod 25 is rotatably connected to the bottom end of the support plate 2. The second threaded rod 21 is rotatably connected to the inner wall of the slide groove 20, and the second threaded block 22 is slidably connected to the inside of the slide groove 20.

[0031] Specifically, the rotation of the second threaded rod 21 drives the second threaded block 22 to slide inside the slide groove 20, thereby causing the support rod 25 to rotate, thereby pushing the angle of the support plate 2 to change. At the same time, the support plate 2 drives the slider 24 to slide along the slide rod 23 through another support rod 25, so that the other support rod 25 plays an auxiliary role and provides support for the support plate 2.

[0032] Reference Figure 3 One end of one of the first threaded rods 11 is fixedly connected to a first synchronous wheel 13, and one end of the other first threaded rod 11 is fixedly connected to a second synchronous wheel 14. The first synchronous wheel 13 and the second synchronous wheel 14 are connected by a belt. The threads on the left and right sides of the outer wall of the first threaded rod 11 are symmetrical, and the longitudinal section of the first threaded block 15 is set to be square.

[0033] Specifically, the first synchronous wheel 13 is driven to rotate by the rotation of the first threaded rod 11, and then the first synchronous wheel 13 drives the second synchronous wheel 14 to rotate through the belt, so that the other first threaded rod 11 is rotated, and then the two clamps 5 are brought close to each other, thereby completing the clamping of the fire door. By setting the outer wall thread of the first threaded rod 11 to be symmetrical on the left and right, when the first threaded rod 11 rotates, the two first threaded blocks 15 slide along the inside of the mounting cover 4 and then approach each other, thereby pushing the clamp 5 to move.

[0034] Working principle: When using this device, first place the fire door to be welded on the support plate 2, then start the first motor 3, the first motor 3 drives the first threaded rod 11 to rotate, so that the two first threaded blocks 11 are close to each other, and then the clamping plate 5 is pushed to slide on the surface of the support plate 2 through the connecting rod 12, and at the same time, the first threaded rod 15 drives the first synchronous wheel 13 to rotate, and then the second synchronous wheel 14 is rotated through the belt, thereby driving another first threaded rod 11 to rotate, and then the same effect is achieved on the other clamping plate 5, pushing the two clamping plates 5 close to each other, thereby achieving the clamping operation of the fire door, so that the steel fire door will not move during welding, thereby affecting the welding effect. Then the second motor 6 can be started, and the second motor 6 drives the second threaded rod 21 to rotate, so that the second threaded block 22 moves along the inner wall of the slide 20, thereby pushing the position of the support rod 25 to change, thereby achieving the angle adjustment of the support plate 2, and the angle of the clamped steel fire door can be changed, thereby facilitating the workers to weld at different positions.

[0035] When welding, first turn on the electric slide rail to move the support frame 8 to a suitable position, push the welding gun 10 to the place where welding is required through the cylinder 9, then start the welding gun 10 for welding, and then start the exhaust fan 17. The smoke generated during welding enters the connecting pipe 19 through the suction hood 7, and is then transmitted to the filter box 16. After being filtered by the filter box 16, it is transmitted to the water tank 18 through a pipeline to absorb the residual gas, thereby reducing the pollution to the environment and the harm to the human body caused by the harmful gases generated during welding.
