When using a welding gun to weld pipes, harmful gases will be generated. Harmful gases will permeate the working environment and affect the physical and mental health of the workers. For this reason, exhaust pipes are installed on the top of some welding equipment to extract the smoke. However, since the exhaust pipes are mostly arranged above the processing table, there is a height difference between them and the pipe welding point. During the welding process, the smoke below the pipe will escape to the surroundings, making it difficult for the exhaust pipes to effectively extract the smoke, and the smoke removal effect is poor.

[0024] To reduce fume pollution and improve the working environment, a fixed plate 20 is provided at the upper end of the fixed base 6. A movable frame 5 is disposed between the two fixed plates 20. The movable frame 5 is detachably connected to the fixed plates 20. A height positioning assembly is provided at the connection between the movable frame 5 and the fixed plates 20. An exhaust pipe is provided at the lower end of the movable frame 5, which is positioned above the welding torch 3. The detachable connection between the movable frame 5 and the fixed plate 20 facilitates replacement. Furthermore, the height of the movable frame 5 can be adjusted using the height positioning assembly to ensure that the exhaust assembly is at the appropriate height, effectively extracting harmful gases generated by the welding torch 3 during welding.

[0025] To further prevent smoke and dust from escaping, a fixed frame 4 is provided between the two fixed seats 6. The fixed frame 4 is fixedly connected to the base 1. A blast pipe is provided at the upper end of the fixed frame 4 and is placed below the welding gun 3. The blast pipe is installed at the upper end of the fixed frame 4 and can blow smoke upward from the bottom of the pipe, increasing the capture rate of smoke by the exhaust pipe and significantly improving the smoke removal effect.

[0026] For the specific structure of the height positioning component, please refer to the following description.

[0027] The height positioning assembly includes a positioning bolt 17, which is assembled on the side of the fixed plate 20 away from the movable frame 5. The positioning bolt 17 is threadedly connected to the positioning hole 18 opened on the outside of the fixed plate 20. The positioning bolt 17 passes through the positioning hole 18 and is threadedly connected to the mounting groove 19 opened on the outside of the movable frame 5. The fixed plate 20 has a plurality of positioning holes 18 on the side away from the movable frame 5, and each positioning hole 18 is evenly arranged along the height direction of the fixed plate 20.

[0028] The height positioning component is used as follows:

[0029] By rotating the positioning bolts 17 and unscrewing them from the mounting slots 19 at both ends of the movable frame 5, the fixing between the movable frame 5 and the fixed plate 20 is released. The operator can then replace the movable frame 5 or adjust the height of the movable frame 5. After adjusting the height of the movable frame 5, the mounting slots 19 at both ends of the movable frame 5 are aligned with one of the positioning holes 18 on the outside of the fixed plate 20, and the corresponding positioning bolts 17 are screwed into the corresponding slots, completing the secondary fixing of the movable frame 5.

[0030] About blast pipe fittings:

[0031] The blast pipe assembly includes multiple exhaust ports 13 located at the top of the fixed frame 4. These ports are connected to a blast duct 14 located within the fixed frame 4. The blast duct 14 is connected to a blower at the end away from the exhaust ports 13. When the blower is activated, gas is discharged from the exhaust ports 13 through the blast duct 14. The upward-blowing gas carries the smoke with it, preventing it from escaping. The specific model and structure of the blower will not be described in detail.

[0032] About exhaust pipe fittings:

[0033] The exhaust ductwork includes multiple air inlets 15 located at the lower end of the movable frame 5. Each air inlet 15 communicates with a negative pressure duct 16 located at the upper end of the movable frame 5. The negative pressure duct 16, remote from the air inlets 15, is connected to a negative pressure dust removal device. When the negative pressure dust removal device is activated, negative pressure air is generated within the negative pressure duct 16, which extracts the fumes generated by the welding torch 3 through the air inlets 15. The specific structure of the negative pressure dust removal device will not be described in detail.

[0034] For the specific structure of the clamping, please refer to the following description.

[0035] The clamping device includes a positioning cylinder 7 provided at the upper end of the fixed seat 6. The positioning cylinder 7 passes through the fixed seat 6 and is rotatably connected to the fixed seat 6. The fixed seat 6 is provided with a rotating drive mechanism for controlling the rotation of the positioning cylinder 7. A plurality of clamping plates 9 are provided on the inner side of the positioning cylinder 7. A plurality of electric push rods 8 are provided on the outer side of the positioning cylinder 7. The mounting end of the electric push rod 8 is fixedly connected to the positioning cylinder 7. The output end of the electric push rod 8 passes through the positioning cylinder 7 and is fixedly connected to the clamping plate 9.

[0036] The way to use the clamp is:

[0037] The two sections of pipe to be welded are placed into the two positioning cylinders 7 respectively. After the two pipes are aligned, the electric push rods 8 push the clamping plates 9 towards the pipes at the same time to fix the pipes inserted into the positioning cylinders 7. During the welding process, the rotary drive mechanism controls the positioning cylinders 7 to rotate, and the pipes also rotate accordingly, allowing the welding gun 3 to weld every area around the pipe.

[0038] It should be further explained that the rotary drive mechanism includes a driving gear 10, a driven gear 11, and a motor 12. The driven gear 11 is sleeved on the outside of the positioning cylinder 7 and fixedly connected to the positioning cylinder 7. The driving gear 10 is placed on the side of the driven gear 11 and meshes with the driven gear 11. The mounting end of the motor 12 is fixedly connected to the fixed base 6, and the output end of the motor 12 is fixedly connected to the driving gear 10. The motor 12 drives the driving gear 10 to rotate, and the driving gear 10, by meshing with the driven gear 11, drives the driven gear 11 and the positioning cylinder 7 to rotate together.

[0039] It should be further explained that the clamping plate 9 is an arc-shaped plate, and a side of the arc-shaped plate away from the electric push rod 8 is provided with an arc-shaped surface that is compatible with the pipeline.

[0040] How this application works:

[0041] The pipes to be welded are fixed by clamping the upper ends of the two fixing seats 6. After the pipes are clamped, the manipulator 2 welds the pipes through the welding gun 3.

[0042] The height of the movable frame 5 can also be adjusted through the height positioning assembly to ensure that the exhaust assembly is at an appropriate height. The blower pipe is installed at the upper end of the fixed frame 4, which can blow the smoke upward from the bottom of the pipe, thereby increasing the capture rate of the smoke by the exhaust pipe and significantly improving the smoke removal effect.
