Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0021] As shown in the attached Figures 1 to 3 A welding device for a pipeline that is convenient for positioning, including a base 1. The base 1 is made of a metal material and serves as a support. On one side above the base 1, there is a fixed support 2. The fixed support 2 is made of a high-hardness metal material, mostly made of stainless steel material. The stainless steel material can make the fixed support 2 have a certain corrosion resistance and extend its service life. The fixed support 2 can ensure the stability and accuracy of pipeline welding. On one side of the fixed support 2, there is a rotating handle 3. The rotating handle 3 is connected to a screw rod 4 through the fixed support 2. By rotating the rotating handle 3, the screw rod 4 can rotate clockwise or counterclockwise on the fixed support 2, thereby driving the displacement of the sliding support 5. One end of the screw rod 4 is provided with a sliding support 5. The sliding support 5 is made of aluminum alloy or high-performance plastic to reduce weight and cost. By selecting appropriate materials, it can be ensured that the slide rail and the slider maintain high precision and stable performance during long-term use. Above the sliding support 5, there is a limiting rod 6. The limiting rod 6 usually needs to bear a certain mechanical load, so it is made of a high-strength and wear-resistant material, such as alloy steel or stainless steel. The limiting rod 6 is usually designed to be cylindrical or square, and its length and diameter / width are optimized according to actual needs to ensure sufficient rigidity and bearing capacity;

[0022] There are two sets of limit rods 6, and the two sets of limit rods 6 are evenly arranged along the horizontal direction of the sliding support 5. The two sets of limit rods 6 arranged horizontally evenly can provide better support force for the sliding support 5. Support rings 7 are provided on the tops of both the fixed support 2 and the sliding support 5. The support rings 7 are usually made of materials with high strength, good rigidity and good corrosion resistance, such as high-strength steel or stainless steel. These materials can ensure that the support rings do not deform when bearing large loads. The support rings 7 can fix the pipeline on the device for welding to ensure the accuracy of welding. A vertical rod 8 is provided on one side of the support ring 7. The vertical rod 8 is made of metal material. One end of the vertical rod 8 is connected with a welding torch 9. The welding torch 9 can weld the pipeline fixed below. The welding torch 9 fixed above the pipeline can maintain the stability of heat input during the welding process. This design helps to achieve uniform weld formation, avoid uneven heat distribution caused by the movement of the welding torch, and thus improve the quality of the welding joint. Embodiment

[0023] Based on Embodiment 1, the solution in Embodiment 1 will be further elaborated in combination with the following specific working methods, as Figures 1 to 3 shown, and the details are described below:

[0024] As a preferred implementation manner, a sliding groove 10 is provided on the upper surface of the base 1. A sliding gear 11 is connected to the bottom of the sliding support 5. When the screw rod 4 rotates clockwise, the sliding gear 11 will drive the sliding support 5 to perform a horizontal displacement along the sliding groove 10. Further, the sliding gear 11 can make the sliding support 5 perform a more stable and accurate displacement under the drive of the screw rod 4, so as to ensure the accuracy and rapidity of welding.

[0025] As a preferred implementation manner, both ends of the two sets of limit rods 6 are fixed to the top of the base 1, so that the sliding support 5 performs a horizontal displacement along the limit rods 6 while displacing along the sliding groove 10. Further, the fixation of the limit rods 6 can prevent the sliding support 5 from exceeding the limit during displacement, thereby causing a change in the welding position of the device.

[0026] As a preferred implementation manner, the support ring 7 is composed of two symmetrical parts. A rotating shaft 12 is provided on one side of the support ring 7, and a fixing hole 13 is provided on the other side of the support ring 7. Further, the structural design of the components of the support ring 7 must consider the mechanical loads it needs to bear. Its shape is usually designed as a semi-circular ring structure to evenly disperse the force transmitted from the support. In order to further improve the strength and rigidity, the cross-section of the support ring may be in the shape of "C" or "I" to increase the bending resistance.

[0027] As a preferred embodiment, a clamping bolt 14 is connected inside the fixing hole 13. The clamping bolt 14 enables the size of the internal hole of the support ring 7 to be adjusted. Further, the clamping bolt 14 transmits force to the workpiece in a point-contact manner. This contact method can achieve a more practical clamping effect. Compared with the traditional surface-contact method, point contact can concentrate force in a smaller area, thereby providing a stronger clamping force to ensure the stability of the pipeline during the welding process.

[0028] As a preferred embodiment, the rotating handle 3 includes a connecting bearing 15 and an operating rod 16. The outer wall of the connecting bearing 15 is connected with the operating rod 16. There are three groups of operating rods 16, and the three groups of operating rods 16 are evenly arranged along the circumferential direction of the connecting bearing 15. Further, the design of the rotating handle 3 makes manual operation easy and intuitive. The operator can control the precise position of the sliding support 5 through a simple rotating action. This compact structure not only saves space in the workplace but also enables the device to be easily integrated into the existing production line.

[0029] The working process of the present utility model is as follows: First, the pipeline to be welded is fixed on the two groups of support rings 7 through the clamping bolt 14. The tightening degree of the support ring 7 is adjusted through the clamping bolt 14 to make the pipeline installation stable. Then, the rotating handle 3 is used to drive the sliding support 5 to drive the pipeline to be welded on one side to displace along the sliding groove 10, so as to abut against the pipeline to be welded in the support ring 7 on the fixed support 2. Then, the welding torch 9 is started to weld the two groups of pipelines in contact below. The welding torch 9 is fixed above the pipeline to maintain the stability of heat input during the welding process. This design helps to achieve uniform weld formation, avoid uneven heat distribution caused by the movement of the welding torch, and thus improve the quality of the welding joint. The above is the working principle of the welding device for a pipeline that is convenient for positioning.

[0030] Finally: The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
