[0002] Stainless steel pipe is a hollow long round steel, which is widely used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instrumentation, and mechanical structural parts. In addition, when the bending and torsional strengths are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures, and is also often used as furniture and kitchen utensils.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0023] See also Figure 1-5 The utility model provides a technical solution: a stainless steel pipe welding fixing device, comprising a workbench 1, two fixing columns 3 are installed on one side of the surface of the workbench 1, and a rotating rod 4 is fixedly installed on the inner wall of the two fixing columns 3 through a bearing, and a guide track 6 is arranged in the middle of the two fixing columns 3, one end of the rotating rod 4 passes through the bottom end of one side of the guide track 6 and is installed on the inner wall of one of the fixing columns 3, a clamping assembly is arranged above the guide track 6, and a lifting assembly is arranged at the bottom end of the other side of the guide track 6, a limit block 505 is fixedly installed above the lifting assembly, and the top of the limit block 505 is fitted and connected with the bottom end of the guide track 6, and a welding assembly is arranged in the middle of the surface of the workbench 1;

[0024] During use, by rotating the rotating rod 4, the guide rail 6 connected to it and the clamping assembly above can be driven to make corresponding angle adjustments, so that the stainless steel pipe can be fine-tuned in angle as needed during welding to ensure the accuracy and quality of welding. The lifting assembly can further fine-tune the position of the guide rail 6 and the clamping assembly above by adjusting its height. When adjusting the welding angle, not only can the angle be changed, but the height and position of the pipe can also be fine-tuned as needed, thereby achieving more accurate welding angle adjustment. By adjusting the clamping assembly, it can be ensured that the pipe remains stable during the welding process and will not loosen or shift due to angle adjustment. Equivalent components are set on both sides of the surface of the workbench 1, so that the device can simultaneously fix two pipes to be welded, and fine-tune the angle and position through their respective adjustment mechanisms. The welding assembly set in the middle of the workbench 1 can conveniently perform welding operations on the adjusted pipes.

[0025] The clamping assembly includes a fixed block 7, a second movable block 701, a second threaded rod 702 and a motor 703. One side of the bottom end of the fixed block 7 is fixedly installed on the side wall of the guide rail 6. The inner wall of the fixed block 7 is provided with a second movable groove 704. The base of the motor 703 is fixedly installed on the top of the fixed block 7. The output shaft of the motor 703 is fixedly connected to one end of the second threaded rod 702. The other end of the second threaded rod 702 is fixedly installed on one side inner wall of the second movable groove 704 through a bearing. One end of the second movable block 701 is threadedly connected to the second threaded rod 702. The bottom end of the second movable block 701 is provided with an arc groove. Driven by the motor 703, the clamping process of the clamping assembly can be automated, reducing the tediousness and errors of manual operation. The arc groove design at the bottom end of the second movable block 701 enables the clamping assembly to adapt to stainless steel pipes of different diameters.

[0026] The surface of the guide rail 6 is provided with arc grooves of equal size, and the inner walls of the two arc grooves are provided with a rubber layer. By providing arc grooves of equal size, the guide rail 6 can better adapt to stainless steel pipes of different shapes and sizes. During the welding process, friction between the pipe and the guide rail 6 is inevitable, and the presence of the rubber layer can reduce this friction and reduce damage to the pipe surface.

[0027] The lifting assembly includes a second support frame 5, a hand-screw piece 504, an internally threaded sleeve 502 and a screw 503. The bottom end of the second support frame 5 is fixedly connected to the surface of the workbench 1. A threaded hole is provided on the surface of the second support frame 5. One end of the screw 503 is threaded through the threaded hole and fixedly connected to the hand-screw piece 504. The screw 503 is threadedly sleeved with the internally threaded sleeve 502. The internally threaded sleeve 502 is arranged on the surface of the second support frame 5. The other end of the screw 503 is fixedly connected to the bottom end of the limit block 505. The threaded sleeve structure of the internally threaded sleeve 502 and the screw 503 ensures the accuracy of the lifting adjustment. By rotating the hand-screw piece 504, the screw 503 can be driven to rotate in the threaded hole and move up and down. Since the other end of the screw 503 is fixedly connected to the bottom end of the limit block 505, the movement of the screw 503 will drive the limit block 505 and the guide rail 6 and the clamping assembly connected thereto to move up and down.

[0028] A telescopic rod 501 is provided at the top of the second support frame 5, and the base of the telescopic rod 501 is fixedly installed on the top surface of the second support frame 5. The piston rod end of the telescopic rod 501 is fixedly connected to the bottom end of the limit block 505. The fixed connection between the telescopic rod 501 and the limit block 505 can ensure that when the height or angle is adjusted, the guide rail 6 and the clamping assembly can maintain a stable posture to avoid shaking or displacement during the welding process.

[0029] A moving assembly is arranged above the welding assembly, and the moving assembly includes a first support frame 2, a driving motor 201, a first threaded rod 202 and a first moving block 203. The first support frame 2 is fixedly installed in the middle of the surface of the workbench 1, and the first support frame 2 is arranged in an inverted U shape. A first moving groove 206 is provided inside the bottom end of the first support frame 2. The base of the driving motor 201 is fixedly installed on one side of the first support frame 2. The output shaft of the driving motor 201 is fixedly connected to one end of the first threaded rod 202. The other end of the first threaded rod 202 is fixedly installed on one side of the inner wall of the first moving groove 206 through a bearing. One end of the first moving block 203 is threadedly connected to the first threaded rod 202. Since the moving assembly has a large moving range and precise adjustment capability, it can adapt to stainless steel pipe welding tasks of different specifications and shapes. Whether it is straight line welding or curve welding, the moving assembly can provide stable and precise support to ensure welding quality.

[0030] The welding assembly includes a cylinder 204 and a welding head 205. The first moving block 203 is arranged in an L shape. The base of the cylinder 204 is fixedly installed on the other end surface of the first moving block 203. The piston rod end of the cylinder 204 passes through the first moving block 203 and is clamped with one end of the welding head 205. A discharge chute 8 is arranged below the welding head 205. The bottom end of the discharge chute 8 is placed on the surface of the workbench 1. The welding head 205 is driven up and down by the cylinder 204 to realize the automation of the welding process. The setting of the discharge chute 8 can conveniently collect the waste generated during the welding process, thereby avoiding the contamination of the workbench 1 and the pipeline by the waste.
