Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, and in particular to a welding device for a water pipe of a sprinkler irrigation machine. Background Art

[0002] As an important equipment for modern agricultural irrigation, the stability and sealing of the water pipe system of the sprinkler is directly related to the irrigation effect and water-saving efficiency. In the manufacturing and installation process of the sprinkler, the welding of the water pipe is a key link. Traditional welding methods are mostly manual, which is not only inefficient, but also the welding quality is greatly affected by human factors, and it is easy to have problems such as uneven welding and leaking welding, which affects the overall performance and service life of the sprinkler.

[0003] With the advancement of agricultural modernization, the requirements for automation and intelligence of sprinkler irrigation pipe welding are getting higher and higher. Although some automated welding equipment has appeared on the market, most of them can only weld one end of the pipe, or require manual assistance to complete loading and unloading processes, and fail to achieve true fully automated welding. Therefore, the development of a welding equipment that can weld both ends of the pipe at the same time and can automatically complete loading and unloading is of great significance to improving the manufacturing efficiency of sprinkler irrigation machines, reducing production costs, and improving irrigation effects.

[0004] When manufacturing existing water supply pipelines, the welding of flanges is mostly single welding, that is, one end of the pipeline is fixed, and then the other end is welded after the welding is completed. This operation method requires more manpower cooperation and requires frequent movement of the pipeline, which affects the work efficiency. It will also cause axial deviation of the two flanges at both ends during welding, and there will be errors in the later connection, resulting in the situation that it cannot be used. Summary of the invention

[0005] In order to solve the above problems, an embodiment of the present invention provides a sprinkler water pipe welding device, which can achieve the purpose of welding flanges at both ends of the pipeline at the same time, improve the welding efficiency, reduce the axial deviation difference between the two flanges and the pipeline, improve the welding yield, and facilitate the subsequent installation and connection of the water pipeline.

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0029] See also Figure 1-7 ,like Figure 1As shown, the water pipe welding equipment for sprinkler irrigation machine of this embodiment comprises a bracket 1 for placing the pipe, a loading platform 28 is placed on one side of the bracket 1, the upper surface of the loading platform 28 is an inclined surface, which is convenient for rolling and unloading the pipe, and a unloading platform 29 is provided on the other side. A positioning module for supporting the pipe is provided in the middle of the bracket 1, and positioning seats 2 for installing flanges are provided at both ends of the bracket 1. A welding module is provided on one side of the positioning seat 2. The positioning module comprises a cross brace 3 located under the pipe, a lifting seat 4 is provided on one side of the cross brace 3, and a mechanical claw 5 for loading and unloading the pipe is provided on the other side. The flange is positioned by the positioning seat 2. After fixing, it is tightened against both ends of the pipeline, and then the welding module is used to weld the flange and the pipeline. The advantage of using this equipment is that the pipeline can be supported and fixed by the positioning module, and then the flange is fixed by the positioning seat 2, and the flange welding operation can be carried out at both ends of the pipeline at the same time, which can effectively improve the welding efficiency, and the two ends are welded synchronously. Compared with the method of welding one end and then welding the other end, there is no need to move the pipeline, which can improve the coaxial distribution of the flanges at both ends, reduce the axial error between the two flanges and the pipeline, and improve the welding quality.

[0030] There are multiple positioning modules, which are evenly distributed along the length direction of the bracket 1 .

[0031] The positioning seat 2 includes a support plate 6 slidably arranged on the bracket 1, a driving motor 7 is arranged above the support plate 6, a turntable 8 is arranged at the output end of the driving motor 7, a transmission rod 11 connected to the driving motor 7 is arranged on one side of the turntable 8, and a storage chamber 12 for placing the flange is arranged on the other side. The storage chamber is designed to match the shape and size of the flange to facilitate the clamping of the flange. An adjustment mechanism is arranged below the support plate 6, and the adjustment mechanism includes a telescopic cylinder 9 arranged on the bracket 1, and a vertical plate 10 connected to the movable end of the telescopic cylinder 9 is arranged on the lower surface of the support plate 6. The telescopic cylinder 9 can drive the positioning seat 2 to move horizontally to achieve the fitting of the flange and the end of the pipeline. During welding, the driving motor 7 can drive the turntable 8 to rotate, thereby driving the pipeline and the flange to rotate synchronously, changing the welding position, and realizing the welding operation along the circumferential direction of the pipeline without moving the welding module.

[0032] A positioning roller 13 is provided on the upper part of the cross brace 3. There are two positioning rollers 13 and they are symmetrically distributed with the center line of the cross brace 3 as the axis. The positioning rollers 13 support the pipeline and reduce the friction with the bracket 1 when the pipeline rotates, so as to facilitate the welding operation.

[0033] The lifting seat 4 includes a lifting cylinder 14 located at the lower part of the bracket 1. The telescopic end of the lifting cylinder 14 is provided with a lifting plate 15. The lifting plate 15 can adjust the height of the pipeline and assist the mechanical claws 5 to adjust the position of the pipeline. The lifting plate 15 is provided with a limiting groove 16 for placing the welding part. The design of the limiting groove 16 can limit the position of the welding part. The welding part here is a fixed seat for supporting the pipeline.

[0034] An extension plate 17 is provided on one side of the lifting plate 15, and a guide block 18 is provided on the extension plate 17. A guide rail 19 used in conjunction with the guide block 18 is provided in the bracket 1. The design of the guide block 18 and the guide rail 19 can guide the lifting plate 15 to ensure the stability of the equipment operation.

[0035] The mechanical claw 5 includes a vertical rod 20 installed on one side of the bracket 1, and a flip arm 21 is hinged at the top of the vertical rod 20. A driving cylinder 22 for driving the flip arm 21 to rotate is provided at the bottom of the flip arm 21. The driving cylinder 22 is designed to be inclined, and the lower end is a fixed end hinged to the bottom of the bracket 1, and the upper end is a telescopic end hinged to the middle part of the flip arm 21. The driving cylinder 22 can drive the flip arm 21 to rise or fall, thereby completing the loading and unloading operation of the material.

[0036] The flip arm 21 includes a horizontal plate 23, one end of which is connected to the vertical rod 20, and the other end is provided with an arc plate 24 for loading and unloading. The inner side of the arc plate 24 is provided with a filling groove for clamping the pipeline, so as to facilitate moving the pipeline to the bracket 1.

[0037] The welding module includes a vertical beam 25 , a slide 26 is provided on the side wall of the vertical beam 25 , and a welding gun 27 is provided on the slide 26 . The height of the welding gun 27 can be adjusted by utilizing the design of the slide 26 .

[0038] When in use: First, the driving cylinder 22 is used to drive the flip arm 21 to flip downward. At this time, the pipe slides from the loading platform 28 and falls into the loading groove on the arc plate 24. The driving cylinder 22 drives the flip arm 21 to rotate upward so that the cross plate 23 remains horizontal. During the rising process, the pipe slides from the loading groove to the cross bar. At this time, the pipe falls between the two positioning rollers 13, and the loading operation is completed;

[0039] After the loading operation is completed, the position of the pipeline needs to be adjusted. First, the two ends of the pipeline are adjusted through the two positioning seats 2 so that the welding position corresponds to the position of the welding module, and then the flange is placed in the storage chamber 12. At this time, the telescopic cylinder 9 is used to drive the positioning seat 2 to push forward so that the flange is tightly fitted against the end of the pipeline, and then the driving motor 7 is rotated and the welding module is used to complete the welding operation of the flange. After the flange welding is completed, the welded part is placed in the limiting groove 16 on the lifting plate 15, and the welding part is lifted up by the lifting cylinder and fits it with the pipeline, and then manual spot welding and fixing are performed. After this step is completed, it is necessary to weld auxiliary parts such as water distribution pipes and connecting plates on the pipeline. At this time, manual spot welding is used for pre-fixing. After the spot welding and fixing are completed, the positioning seat 2 moves backward, and the driving cylinder 22 is started to drive the driving arm 21 to continue to flip upward, and the welded pipeline is transferred to the unloading platform 2.
