[0031] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0032] Example 1, as shown in Figure 1 , Figure 2 and Figure 3As shown in the figure, a full-position pipe welding device includes a housing 1. At the rear side edge of the left part of the upper end and the front side edge of the left part of the upper end of the housing 1, semi-circular platforms 2 are fixedly connected. A covering component 3 is slidably installed on the outer surfaces of the two semi-circular platforms 2. A marking component 4 is slidably installed on the inner surface of the covering component 3. By setting the covering component 3 and the marking component 4 and using them in cooperation, before welding the pipe, the surface of the pipe to be welded can be marked, which is convenient for adjusting the welding position of the pipe and avoiding the situation of welding position deviation.

[0033] Clamping components 5 are slidably installed on the inner surface of the housing 1 and the inner surface of the covering component 3. By setting the clamping components 5, pipes of different specifications can be limited and clamped, and after the pipes are clamped, the normal rotary welding of the pipes will not be affected.

[0034] A grinding component 6 is fixedly installed on the bottom wall of the housing 1. By setting the grinding component 6, the surface of the welded pipe can be ground, thereby improving the subsequent welding effect and optimizing the aesthetics of the subsequent pipe welding.

[0035] A driving component 7 is slidably installed at the rear end of the housing 1. By setting the driving component 7, it can adaptively drive the position and adjust the up and down position according to pipes of different specifications, so as to be applicable to the welding processing of pipes of different specifications.

[0036] Embodiment 2. On the basis of Embodiment 1, for the purpose of clamping pipes of different specifications.

[0037] Specifically, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 10 The covering component 3 includes an arc plate 31 slidably connected to the mutually approaching ends of the two semi-circular platforms 2. Arc plates 32 are fixedly connected to the front end and the rear end of the arc plate 31. The outer surfaces of the two arc plates 32 are respectively slidably connected to the outer surfaces of the two semi-circular platforms 2. A hollow plate 33 is fixedly connected to the right side of the mutually approaching ends of the two arc plates 32. A laser welding torch 34 is slidably connected to the inner surface of the hollow plate 33.

[0038] Further, the clamping assembly 5 includes a number of guide posts 51. A number of guide grooves 52 are annularly arrayed on the inner arc surfaces of the front side and the rear side of the outer shell 1 and the inner arc surfaces of the two arc plates 32. The number of guide posts 51 are respectively slidably connected to the inner cavities of the number of guide grooves 52. The ends of the number of guide posts 51 on the left side and the right side, which are far away from the guide grooves 52 on the same side, are all fixedly connected together with an arc-shaped hollow clamping plate 54. 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 clamping plate 56. A number of rollers 55 are rotatably connected to the inner arc surfaces of the arc-shaped hollow clamping plates 54 on the same side in an annular array. A number of second springs 53 are fixedly connected to the outer arc surfaces of the arc-shaped hollow clamping plates 54 and the arc-shaped solid clamping plates 56 on the same side in an annular array. The other ends of the number of second 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. The number of second springs 53 are respectively located outside the number of guide posts 51. The arc-shaped solid clamping plates 56 on the same side are respectively fixedly connected to the number of guide posts 51 on the same side.

[0039] First, place the pipe to be welded and processed on the inner arc surfaces of the four arc-shaped hollow clamping plates 54 on the lower side. At this time, the two arc-shaped hollow clamping plates 54 at the front part on the lower side and the two arc-shaped hollow clamping plates 54 at the rear part on the lower side will be affected by the self-weight and size of the pipe, expand outward on the outer surfaces of the arc-shaped solid clamping plates 56 on the same side, and the arc-shaped solid clamping plates 56 at the lower part will move downward. The arc-shaped hollow clamping plates 54 and the arc-shaped solid clamping plates 56 on the lower side will simultaneously squeeze the guide posts 51 fixedly connected to them into the corresponding guide grooves 52, and the second springs 53 on the same side will be simultaneously squeezed and contracted;

[0040] Since the two arc plates 32 are connected by the arc plate 31, when moving one arc plate 32 from left to right, the other arc plate 32 will move simultaneously. The moving process of the two arc plates 32 is to rotate from left to right with the center of the semi-circular platform 2 as the axis point, and then the right lower ends of the two arc plates 32 can cover the upper end of the outer shell 1;

[0041] After the two arc plates 32 are completely covered, the four arc-shaped hollow clamping plates 54 and the two arc-shaped solid clamping plates 56 on the upper side will be simultaneously squeezed outward and upward according to the pipe specifications. The operating principles of the number of guide grooves 52 and the number of second springs 53 on the upper side are the same as those described above, so no more details will be elaborated;

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

[0043] Therefore, through the provided covering component 3 and clamping component 5 in this solution, pipes of different specifications can be limited and clamped, thereby improving the versatility of the device.

[0044] Embodiment 3. On the basis of Embodiment 2, for the purpose of marking the surface of the pipe to be welded before welding the pipe.

[0045] Specifically, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 , the marking component 4 includes a sliding plate 41. Arc-shaped grooves 42 are respectively opened in the middle of one end of the two arc-shaped plates 31 close to each other. The left side and the right side of the outer surface of the sliding plate 41 are respectively slidably connected to the inner cavity of the arc-shaped groove 42 on the same side. The left side wall and the right side wall of the inner surface of the arc-shaped groove 42 on the same side are both fixedly connected with arc-shaped rods 43 in common. Both arc-shaped rods 43 are slidably connected to the inner surface of the sliding plate 41. The right end of the sliding plate 41 and the left side wall of the inner surface of the two arc-shaped grooves 42 are both fixedly connected with arc-shaped springs 44 in common. The two arc-shaped springs 44 are respectively wound around the outer surface of the arc-shaped rod 43 on the same side. A chute 45 penetrating the lower part of the outer surface of the sliding plate 41 is opened in the middle of the upper side of the outer surface of the sliding plate 41. A slider 46 is slidably connected to the upper side of the outer surface of the sliding plate 41. A marking pen 47 is slidably connected to the inner surface of the slider 46. A first spring 48 is fixedly connected to the side where the slider 46 and the marking pen 47 are close to each other. The lower part of the outer surface of the marking pen 47 is slidably connected to the inner cavity of the chute 45.

[0046] After the two arc-shaped plates 32 are covered as described above, when the surface of the pipe to be welded needs to be marked at this time, only need to push the marking pen 47, so that the marking pen 47 drives the slider 46 to slide on the surface of the sliding plate 41. After sliding to the position where marking is required, at this time, only need to press down the marking pen 47, so that the marking pen 47 squeezes the first spring 48 fixedly connected thereto, so that the marking end of the marking pen 47 contacts the surface of the pipe. Then, push the marking pen 47 to the right, so that the marking pen 47 drives the sliding plate 41 to slide simultaneously in the arc-shaped grooves 42 on both sides, thereby enabling the marking end of the marking pen 47 to draw the arc mark required for marking on the surface of the pipe;

[0047] When the marking is completed, only need to release the grip on the marking pen 47. At this time, the sliding plate 41 rebounds to the initial state under the action of the arc-shaped springs 44 on both sides, and the arc-shaped rods 43 on both sides play a guiding role. At the same time, the first spring 48 squeezed by the marking pen 47 also rebounds, prompting the marking end of the marking pen 47 to leave the surface of the pipe and then return to the initial state. Then, according to the arc line marked on the surface of the pipe, align the arc line with the welding head position of the laser welding torch 34 to start the subsequent processing work;

[0048] Therefore, in this solution, by setting the marking component 4, it is convenient to perform welding marks on the surface of the pipeline, improving the subsequent pipeline welding efficiency.

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

[0050] Example 4. On the basis of Example 3, this example aims to achieve adaptive adjustment of the driving position when performing rotary welding processing on the pipeline.

[0051] Specifically, referring to Figure 1 、 Figure 3 、 Figure 6 、 Figure 8 、 Figure 9 and Figure 10 , the driving component 7 includes a rectangular plate 71. A rectangular groove 72 is opened in the middle of the rear end of the housing 1. The rectangular plate 71 is slidably connected to the inner cavity of the rectangular groove 72. Three limit rods 73 distributed linearly in an array are slidably connected to the inner surface of the rectangular plate 71. The upper and lower ends of the three limit rods 73 are respectively fixedly connected to the top wall and the bottom wall of the rectangular groove 72. Three spring fours 74 are fixedly connected to the bottom wall of the rectangular groove 72 and the lower end of the rectangular plate 71 together. The three spring fours 74 are respectively located outside the three limit rods 73. The upper part of the rear end of the rectangular plate 71 is rotatably connected to a connecting rod 75. The rear end of the connecting rod 75 is fixedly connected to a friction roller 76. The lower part of the rear end of the rectangular plate 71 is fixedly connected to a support platform 77. The middle rear side of the upper end of the support platform 77 is fixedly connected to a motor 78. The output end of the motor 78 is fixedly connected to the friction roller 76 through a coupling.

[0052] After completing the preliminary preparation process before welding processing through the above embodiments, at this time, the pipeline is also limited and fixed. During the process of limiting and fixing, the outer wall of the pipeline will press against and contact the surface of the friction roller 76. Subsequently, the friction roller 76 drives the connecting rod 75, the motor 78, and the support platform 77 connected thereto to move downward simultaneously. 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. At the same time, the three limit rods 73 play a role of limiting and guiding. At the same time, the lower end of the rectangular plate 71 can squeeze and contract the spring fours 74 located outside the three limit rods 73. Subsequently, 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 is in contact with the outer wall of the pipeline, friction is generated, driving the pipeline to rotate slowly;

[0053] When the pipe rotates, since a number of rollers 55 are rotatably connected to the inner arc surfaces of the arc-shaped hollow clamping plates 54, the number of rollers 55 can assist the pipe in rotating and processing, and then the welding head of the laser welding torch 34 starts to weld and process the surface of the pipe.

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

[0055] Laser generation: The laser welding torch 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 thin laser beam through an optical system;

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

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

[0058] Cooling and solidification of the molten pool: The work of the laser welding torch 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 solidifies again to complete the welding process and form a firm joint;

[0059] Gas protection: In order to prevent the molten pool from contacting the air at high temperature and undergoing an oxidation reaction, a shielding gas, such as nitrogen, argon, etc., is usually used during the laser welding process to protect the welding area.

[0060] Therefore, the above-mentioned laser welding torch 34 is a conventional design in the prior art, and its specific installation method, circuit connection method, and control method are all conventional designs, and the scheme will not be elaborated in detail.

[0061] Embodiment 5. On the basis of Embodiment 4, this embodiment aims to lock the device during processing and polish the surface of the pipe at the same time.

[0062] Specifically, referring to Figure 1 、 Figure 2 、 Figure 3 、 Figure 6 、 Figure 7 and Figure 10 , the polishing assembly 6 includes a hollow platform 61 fixedly connected to the middle of the bottom wall of the housing 1. A cylinder 62 is slidably connected to the inner surface of the hollow platform 61. The upper end of the cylinder 62 is fixedly connected to a polishing plate 63. A third spring 64 is fixedly connected to the lower side of the outer surface of the polishing plate 63 and the upper end of the hollow platform 61. The third spring 64 is located outside the cylinder 62.

[0063] Further, a sandpaper is fixedly connected to the outer surface of the grinding plate 63.

[0064] Further, a plurality of rollers 55 and friction rollers 76 are both made of rubber.

[0065] Further, a hollow threaded plate one 81 is fixedly connected to the front right edge of the front arc plate 32, and a hollow threaded plate two 82 is fixedly connected to the upper right edge of the front end of the housing 1. A bolt 83 is commonly threadedly connected to the inner surfaces of the hollow threaded plate one 81 and the hollow threaded plate two 82. A hollow threaded ring 84 is fixedly connected to the lower end of the hollow threaded plate two 82, and the inner surface of the hollow threaded ring 84 is threadedly connected to the outer surface of the bolt 83.

[0066] As can be seen from the above, after the two arc plates 32 contact the upper end of the housing 1, at this time, the bolt 83 can be rotated through the hollow threaded plate one 81 and the hollow threaded plate two 82 that are threadedly connected to it, and the hollow threaded ring 84 is fixedly connected to the lower end of the hollow threaded plate two 82. At the same time, the hollow threaded ring 84 is threadedly connected to the bolt 83. Therefore, after the bolt 83 rotates into the inner cavity of the hollow threaded ring 84, the hollow threaded plate two 82 and the hollow threaded plate one 81 can be connected together, thereby fixing the arc plate 32;

[0067] Then, during the rotation of the pipeline, in order to avoid scratching the surface of the pipeline and affecting the subsequent processing aesthetics, in this solution, by setting a plurality of rollers 55 and friction rollers 76 to be made of rubber, the rotation stability of the pipeline during processing is improved, and the rubber material can avoid scratching the surface of the pipeline;

[0068] When the pipeline rotates, the pipeline can contact the grinding plate 63. Subsequently, the grinding plate 63 presses the cylinder 62 and the spring three 64, causing the cylinder 62 to slide into the inner cavity of the hollow table 61. Under the action of the spring three 64, the grinding plate 63 can always fit on the surface of the pipeline. As can be seen from the above, a sandpaper is fixedly connected to the outer surface of the grinding plate 63. Therefore, when the pipeline rotates, the sandpaper fixedly connected to the surface of the grinding plate 63 can continuously grind the surface of the pipeline, thereby improving the subsequent processing aesthetics.

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

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

[0071] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements fall within the scope of the present invention claimed. The scope of the present invention claimed is defined by the appended claims and their equivalents.
