[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1, as Figure 1 , Figure 2 and Figure 3As shown, an all-position pipeline welding device comprises a shell 1, a semi-circular table 2 is fixedly connected at the left rear edge of the upper end and the left front edge of the upper end of the shell 1, a covering component 3 is slidably mounted on the outer surfaces of the two semi-circular tables 2, and a marking component 4 is slidably mounted on the inner surface of the covering component 3. By setting the covering component 3 and the marking component 4, the two are used in coordination, and the surface of the pipeline to be welded can be marked before welding the pipeline, so as to facilitate the adjustment of the welding position of the pipeline and avoid the situation of welding position deviation;

[0033] The inner surface of the housing 1 and the inner surface of the cover assembly 3 are both slidably mounted with a clamping assembly 5, through which pipes of different specifications can be clamped in a limited position, and after the pipes are clamped, the normal rotation welding of the pipes will not be affected;

[0034] A grinding assembly 6 is fixedly installed on the bottom wall of the housing 1. The grinding assembly 6 can be used to grind the surface of the pipe after welding, thereby improving the subsequent welding effect and optimizing the aesthetics of the subsequent pipe welding.

[0035] A driving assembly 7 is slidably mounted at the rear end of the housing 1. The driving assembly 7 can adaptively drive the position according to pipes of different specifications, and adjust the up and down positions, thereby being suitable for welding processing of pipes of different specifications.

[0036] Embodiment 2: This embodiment is based on Embodiment 1 and is for achieving the purpose of clamping pipes of different specifications.

[0037] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Fig.10 The covering assembly 3 includes an arc plate 31 that is slidably connected to the ends of the two semi-circular cones 2 that are close to each other. The front and rear ends of the arc plate 31 are fixedly connected to arc plates 32. The outer surfaces of the two arc plates 32 are slidably connected to the outer surfaces of the two semi-circular cones 2 respectively. A hollow plate 33 is fixedly connected to the right side of the ends of the two arc plates 32 that are close to each other, and a laser welding gun 34 is slidably connected to the inner surface of the hollow plate 33.

[0038] Furthermore, the clamping assembly 5 includes a plurality of guide posts 51, the inner arc surfaces of the housing 1 located at the front side and the rear side and the inner arc surfaces of the two arc plates 32 are provided with a plurality of guide grooves 52 in an annular array, the plurality of guide posts 51 are respectively slidably connected to the inner cavities of the plurality of guide grooves 52, the ends of the plurality of guide posts 51 located at the left side and the right side away from the guide grooves 52 on the same side are both fixedly connected with an arc-shaped hollow clamping plate 54, and the inner surfaces of the two arc-shaped hollow clamping plates 54 on the same side are both slidably connected with an arc-shaped solid The splint 56 and the inner arc surfaces of the arc-shaped hollow splint 54 on the same side are rotatably connected to a number of rollers 55 in a circular array, and the outer arc surfaces of the arc-shaped hollow splint 54 on the same side and the arc-shaped solid splint 56 on the same side are fixedly connected to a number of springs 53 in a circular array, and the other ends of the number of springs 53 are respectively fixedly connected to the inner arc surfaces of the two arc plates 32 and the two inner arc surfaces of the outer shell 1, and the number of springs 53 are respectively located on the outside of the number of guide columns 51, and the arc-shaped solid splints 56 on the same side are respectively fixedly connected to the number of guide columns 51 on the same side.

[0039] First, place the pipe to be welded on the inner arc surface of the four arc-shaped hollow clamps 54 located at the lower side. At this time, the two arc-shaped hollow clamps 54 located at the front of the lower side and the two arc-shaped hollow clamps 54 located at the rear of the lower side will be affected by the weight and size of the pipes themselves, and the outer surface of the arc-shaped solid clamps 56 on the same side will expand outward, and the arc-shaped solid clamps 56 located at the lower part will move downward. The arc-shaped hollow clamps 54 and the arc-shaped solid clamps 56 located at the lower side will squeeze the guide column 51 fixedly connected thereto into the corresponding guide groove 52 at the same time, and the spring 2 53 on the same side will be squeezed and contracted at the same time;

[0040] Since the two arc plates 32 are connected by the arc plate 31, when the arc plate 32 on one side is moved from left to right, the arc plate 32 on the other side also moves simultaneously. The moving process of the two arc plates 32 is to rotate from left to right with the center of the semi-circular table 2 as the axis point, and then the right lower ends of the two arc plates 32 are covered on the upper end of the housing 1.

[0041] After the two arc plates 32 are covered, the four arc hollow clamping plates 54 and the two arc solid clamping plates 56 on the upper side are simultaneously pressed outward and upward according to the pipe specifications, and the operating principles of the plurality of guide grooves 52 and the plurality of springs 53 on the upper side are the same as above, so no further elaboration is made;

[0042] After the pipeline is fixed in position, the laser welding gun 34 can be pushed inward, so that the laser welding gun 34 gradually approaches the outer wall of the pipeline in the inner cavity of the hollow plate 33 until it moves to a suitable welding processing position. The specific welding processing position can be adjusted according to actual processing requirements.

[0043] Therefore, the present invention can limit and clamp pipes of different specifications by providing the covering assembly 3 and the clamping assembly 5, thereby improving the versatility of the device.

[0044] Embodiment 3: This embodiment is based on Embodiment 2 and is for achieving the purpose of marking the surface of the pipeline to be welded before welding the pipeline.

[0045] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The marking component 4 includes a slide plate 41, and an arc groove 42 is provided in the middle part of one end of the two arc plates 31 close to each other. The left side and the right side of the outer surface of the slide plate 41 are respectively slidably connected to the inner cavity of the arc groove 42 on the same side, and the left side wall and the right side wall of the inner surface of the arc groove 42 on the same side are fixedly connected with an arc rod 43. The two arc rods 43 are both slidably connected to the inner surface of the slide plate 41, and the right end of the slide plate 41 and the left side walls of the inner surfaces of the two arc grooves 42 are fixedly connected with an arc spring 44. The two arc springs 44 are respectively wound around the outer surfaces of the arc rods 43 on the same side. A slide groove 45 that runs through the lower part of the outer surface of the slide plate 41 is provided in the middle part of the upper side of the outer surface of the slide plate 41, a slider 46 is slidably connected to the upper side of the outer surface of the slide plate 41, and a marking pen 47 is slidably connected to the inner surface of the slider 46. A spring 48 is fixedly connected to the side where the slider 46 and the marking pen 47 are close to each other, and the lower part of the outer surface of the marking pen 47 is slidably connected to the inner cavity of the slide groove 45.

[0046] After the two arc plates 32 are covered as described above, when it is necessary to mark the surface of the welded pipe, it is only necessary to push the marking pen 47 so that the marking pen 47 drives the slider 46 to slide on the surface of the slide plate 41. After sliding to the position where the marking is required, it is only necessary to press the marking pen 47 downward so that the marking pen 47 squeezes the spring 1 48 fixedly connected thereto so that the marking end of the marking pen 47 contacts the pipe surface. Then, the marking pen 47 is pushed to the right so that the marking pen 47 drives the slide plate 41 to slide in the arc grooves 42 on both sides at the same time, thereby making the marking end of the marking pen 47 draw the arc mark required for marking on the pipe surface.

[0047] When the marking is finished, just release the grip on the marking pen 47. At this time, the slide plate 41 rebounds to the initial state under the action of the arc springs 44 on both sides, and the arc rods 43 on both sides play a guiding role. At the same time, the spring 48 squeezed by the marking pen 47 also rebounds, causing the marking end of the marking pen 47 to leave the pipe surface and then return to the initial state. Then, according to the arc line marked on the pipe surface, the arc line can be aligned with the welding head position of the laser welding gun 34 to start the subsequent processing work;

[0048] Therefore, the marking component 4 provided in this solution facilitates welding marking on the pipeline surface, thereby improving the subsequent pipeline welding efficiency.

[0049] The above-mentioned key marking pen 47 is a conventional setting in the prior art. In this solution, it only needs to meet the requirement that the liquid used for marking can appear when it contacts the surface of the pipeline. Its specific shape can be adjusted according to actual production requirements, so this solution will not be elaborated in detail.

[0050] Embodiment 4: Based on embodiment 3, this embodiment is for achieving the purpose of adaptively adjusting the driving position when performing rotation welding processing on the pipeline.

[0051] For details, see Figure 1 , Figure 3 , Figure 6 , Figure 8 , Fig. 9 and Fig.10 The driving assembly 7 includes a rectangular plate 71, a rectangular groove 72 is provided in the middle of the rear end of the shell 1, the rectangular plate 71 is slidably connected to the inner cavity of the rectangular groove 72, and three limiting rods 73 distributed in a linear array are slidably connected to the inner surface of the rectangular plate 71, and the upper and lower ends of the three limiting rods 73 are respectively fixedly connected to the top wall and the bottom wall of the rectangular groove 72, and three springs four 74 are fixedly connected to the bottom wall of the rectangular groove 72 and the lower end of the rectangular plate 71, and the three springs four 74 are respectively located on the outside of the three limiting rods 73, and a connecting rod 75 is rotatably connected to the upper part of the rear end of the rectangular plate 71, and a friction roller 76 is fixedly connected to the rear end of the connecting rod 75, and a support platform 77 is fixedly connected to the lower part of the rear end of the rectangular plate 71, and a motor 78 is fixedly connected to the rear side of the middle part of the upper end of the support platform 77, and the output end of the motor 78 is fixedly connected to the friction roller 76 through a coupling.

[0052] After the preliminary preparation process before welding is completed through the above embodiment, the pipeline is also limited and fixed at this time. During the process of limiting and fixing, the outer wall of the pipeline will press and contact the surface of the friction roller 76, and then the friction roller 76 drives the connecting rod 75, the motor 78 and the support platform 77 connected thereto to move downward at the same time. When moving downward, since the support platform 77 is fixedly connected to the rectangular plate 71, the rectangular plate 71 will move downward on the inner surface of the rectangular groove 72, and the three limiting rods 73 play a role of limiting guide. At the same time, the lower end of the rectangular plate 71 can squeeze and contract the spring four 74 located on the outer side of the three limiting rods 73, and then by starting the motor 78, the output end of the motor 78 drives the friction roller 76 fixedly connected thereto to rotate through the coupling. Since the friction roller 76 fits against the outer wall of the pipeline, friction is generated, which drives the pipeline to rotate slowly.

[0053] When the pipe rotates, the inner arc surface of the arc hollow clamping plate 54 is rotatably connected to the rollers 55, so that the rollers 55 can assist the pipe in rotating processing, and then the welding head of the laser welding gun 34 starts to weld the pipe surface.

[0054] The laser welding gun 34 mentioned above is a conventional setting in the prior art, and its working principle is as follows:

[0055] Laser generation: The laser welding gun 34 generates a high-intensity laser beam through a laser, such as a fiber laser, a CO2 laser, etc. The laser converts electrical energy into light energy and focuses it into a very fine laser beam through an optical system;

[0056] Focused laser beam: The laser beam is focused through an optical lens, such as a lens. The focused laser beam has a high energy density and can generate high temperatures on the surface of the material;

[0057] Welding process: When the laser beam is irradiated on the welding material, the surface of the material is quickly heated to the melting point and a molten pool is formed. The strong heat of the laser beam causes the metal to melt locally to form a fused joint;

[0058] Molten pool cooling and solidification: The work of the laser welding gun 34 is not only to heat the metal, but also depends on the rapid cooling of the welding area. After the molten pool cools, the metal re-solidifies, completing the welding process and forming a strong seam;

[0059] Gas protection: In order to prevent the molten pool from oxidizing when it comes into contact with air at high temperature, shielding gases such as nitrogen and argon are usually used during laser welding to protect the welding area.

[0060] Therefore, the laser welding gun 34 described above is of conventional design in the prior art, and its specific installation method, circuit connection method and control method are all of conventional design, and the scheme will not be described in detail.

[0061] Embodiment 5: Based on Embodiment 4, this embodiment is for achieving the purpose of locking the device during processing and polishing the surface of the pipeline at the same time.

[0062] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Fig.10 The grinding assembly 6 includes a hollow platform 61 fixedly connected to the middle part of the bottom wall of the shell 1, a cylinder 62 is slidably connected to the inner surface of the hollow platform 61, a grinding plate 63 is fixedly connected to the upper end of the cylinder 62, and a spring three 64 is fixedly connected to the lower side of the outer surface of the grinding plate 63 and the upper end of the hollow platform 61, and the spring three 64 is located outside the cylinder 62.

[0063] Furthermore, sandpaper is fixedly connected to the outer surface of the sanding plate 63 .

[0064] Furthermore, the plurality of rollers 55 and the friction roller 76 are all made of rubber material.

[0065] Furthermore, a hollow threaded plate 81 is fixedly connected to the right edge of the front end of the front arc plate 32, and a hollow threaded plate 82 is fixedly connected to the upper right edge of the front end of the shell 1. The inner surfaces of the hollow threaded plate 81 and the hollow threaded plate 82 are threadedly connected with a bolt 83. The lower end of the hollow threaded plate 82 is fixedly connected with a hollow thread ring 84, and the inner surface of the hollow thread ring 84 is threadedly connected to the outer surface of the bolt 83.

[0066] It can be known from the above that after the two arc plates 32 are in contact with the upper end of the housing 1, the bolt 83 can be rotated through the hollow threaded plate 1 81 and the hollow threaded plate 2 82 which are threadedly connected thereto, and the hollow thread ring 84 is fixedly connected to the lower end of the hollow threaded plate 2 82, and the hollow thread ring 84 is threadedly connected to the bolt 83. Therefore, after the bolt 83 is rotated into the inner cavity of the hollow thread ring 84, the hollow threaded plate 2 82 and the hollow threaded plate 1 81 can be connected together, thereby fixing the arc plate 32;

[0067] Then, in the process of pipe rotation, in order to avoid scratching the pipe surface and affecting the aesthetics of subsequent processing, in this solution, the plurality of rollers 55 and the friction roller 76 are all made of rubber material, thereby improving the stability of the pipe rotation during processing, and the rubber material can avoid scratching the pipe surface;

[0068] When the pipeline rotates, the pipeline can contact the polishing plate 63, and then the polishing plate 63 squeezes the cylinder 62 and the spring three 64, so that the cylinder 62 slides into the inner cavity of the hollow platform 61, and under the action of the spring three 64, the polishing plate 63 can always fit the surface of the pipeline. From the above, it can be seen that the outer surface of the polishing plate 63 is fixedly connected with sandpaper. Therefore, when the pipeline rotates, the sandpaper fixedly connected to the surface of the polishing plate 63 can continuously polish the surface of the pipeline, thereby improving the subsequent processing aesthetics.

[0069] The sandpaper mentioned above is a conventional setting in the prior art, and its specific particle size can be adjusted according to actual production needs, so this solution will not be elaborated in detail.

[0070] It should be noted that the specific installation method, circuit connection method and control method of the motor 78 and the laser welding gun 34 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0071] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected. The scope of protection of the present invention is defined by the attached claims and their equivalents.
