DETAILED DESCRIPTION

[0036] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0037] like Figure 1 The special-shaped pipe fitting 9 shown is used as a heat exchange tube. The special-shaped pipe fitting 9 is a three-dimensional structure, including a first welding section 91, a second welding section 92, a third welding section 93, a fourth welding section 94, a fifth welding section 95, a sixth welding section 96 and a seventh welding section 97, wherein the second welding section 92, the fourth welding section 94 and the sixth welding section 96 are bent pipes.

[0038] See also Figure 2-Figure 9 The present invention provides a technical solution: an intelligent welding platform for special-shaped pipe fittings 9, comprising a horizontal welding platform 1 and a vertical welding platform 2, wherein the horizontal welding platform 1 is fixed at 90° to the vertical welding platform 2, a horizontal welding device 3 is provided in the horizontal welding platform 1, and a vertical welding device 4 is provided in the vertical welding platform 2, both the horizontal welding device 3 and the vertical welding device 4 are provided with a main body 6, a clamping mechanism 7 and a welding mechanism 8, and both the horizontal welding platform 1 and the vertical welding platform 2 are provided with a plurality of clamping components 5.

[0039] Through the above technical solution, the third welding section 93, the fourth welding section 94, and the fifth welding section 95 of the special-shaped pipe fitting 9 are placed on the horizontal welding platform 1, the second welding section 92 and the sixth welding section 96 are placed at the angle between the horizontal welding platform 1 and the vertical welding platform 2, and the first welding section 91 and the seventh welding section 97 are placed on the vertical welding platform 2. After the adjacent pipe fittings are aligned, they are fixed by the clamping assembly 5, and the horizontal welding device 3 and the vertical welding device 4 are welded separately or simultaneously to realize the welding of the three-dimensional special-shaped pipe fitting 9. The intelligent welding platform can reduce the steps of clamping and adjusting the special-shaped pipe fitting 9, improve the welding quality, and the use of machine automatic welding can improve the welding quality and welding efficiency.

[0040] like Figure 3 , Figure 4 and Figure 7 As shown, the horizontal welding device 3 in this scheme is specifically described.

[0041] The main body 6 of the horizontal welding device 3 is a U-shaped structure. Both sides of the main body 6 are provided with through holes 63 for the special-shaped pipe fittings 9 to pass through. The groove of the U-shaped structure in the middle of the main body 6 is a welding cavity 61. A fixing ring 62 is provided on the outer edge of the welding cavity 61 corresponding to the through hole 63.

[0042] Furthermore, the welding mechanism 8 is located in the welding cavity 61, and the welding mechanism 8 includes a mounting ring 81, a driving assembly and a welding gun 82. The two ends of the mounting ring 81 are respectively mounted outside the two fixed rings 62 and are rotatably connected to the fixed rings 62 through bearings 86. The welding gun 82 is located in the middle of the mounting ring 81 and extends into the mounting ring 81 for welding.

[0043] Through the above technical solution, two adjacent segmented pipes extend into the mounting ring 81 from the through holes 63 on both sides respectively, and the butted welds are located below the welding gun 82 , through which the segmented pipes are welded.

[0044] Furthermore, the driving assembly includes a gear ring 83 and a gear motor 84 . The gear ring 83 is sleeved outside the mounting ring 81 . The gear 72 of the gear motor 84 meshes with the gear ring 83 . The motor seat of the gear motor 84 is fixed on the main body 6 in the welding cavity 61 .

[0045] Through the above technical solution, the gear ring 83 is sleeved outside the mounting ring 81 and fixed to the mounting ring 81 as a whole, and the gear ring 83 is driven to rotate by the gear motor 84, thereby driving the mounting ring 81 and the welding gun 82 on the mounting ring 81 to rotate, so as to realize automatic welding of a circle of the pipe fitting, thereby improving the welding quality and welding efficiency. The welding can be carried out by argon arc welding, plasma welding, etc., and the specific welding method is rotated according to the pipe fitting material.

[0046] Furthermore, the mounting ring 81 is provided with an opening for the welding gun 82 to extend therein, a telescopic cylinder 85 is provided on the top of the welding gun 82 , a cylinder seat of the telescopic cylinder 85 is fixedly connected to the mounting ring 81 , and a piston rod of the telescopic cylinder 85 is connected to the welding gun 82 .

[0047] Through the above technical solution, the depth of the welding gun 82 inserted into the mounting ring 81 can be adjusted by the telescopic cylinder 85, so that the welding gun 82 can be inserted into the appropriate position of the weld seam to improve the welding effect. It can be known that the corresponding pipeline of the welding gun 82 has a margin, which can ensure that the welding gun 82 rotates one circle, and the welding gun 82 automatically resets after rotating one circle to avoid pipeline entanglement.

[0048] Furthermore, two clamping mechanisms 7 are symmetrically provided on both sides of the main body 6, and the clamping mechanism 7 includes a bidirectional clamping mechanism and a rack lifting mechanism. The two bidirectional clamping mechanisms are symmetrically arranged on both sides of the through hole 63, and the bidirectional clamping mechanism includes a gear 72, a first rack 71 and a second rack 73. The gear 72 is located between the first rack 71 and the second rack 73, and the gear 72 is rotatably connected to the main body 6. The bottoms of the first rack 71 and the second rack 73 are respectively slidably connected to the main body 6, and the first rack 71 and the second rack 73 are respectively meshed with the gear 72.

[0049] Through the above technical solution, the second rack 73 can be moved in the opposite direction to the first rack 71 by pushing the first rack 71. Since the two first racks 71 and the two second racks 73 are connected by connecting rods 74 respectively, and detachable clamping blocks 75 are symmetrically provided in the middle of the two connecting rods 74, the two clamping blocks 75 can move in the opposite direction, thereby realizing synchronous clamping or synchronous loosening of the pipe fittings.

[0050] Furthermore, the rack lifting mechanism includes a rotating motor 76 and a reversing mechanism 77, the rotating motor 76 and the reversing mechanism 77 are fixed on the main body 6, the reversing mechanism 77 and the rotating motor 76 are connected by a transmission shaft, and a reversing mechanism 77 is provided under each first rack 71, and the lifting rack in the reversing mechanism 77 is fixed to the bottom of the first rack 71.

[0051] Through the above technical solution, the rotating motor 76 drives the transmission shaft to rotate, and the transmission shaft realizes the vertical movement of the rack in the reversing mechanism 77 through the reversing mechanism 77. Since the rack in the reversing mechanism 77 is fixed to the first rack 71, the movement of the two clamping blocks 75 can be realized by rotating the motor 76, thereby realizing the clamping and releasing actions, which can improve the clamping efficiency and ensure the clamping effect.

[0052] At the same time, the rotary motor 76 of the horizontal welding device 3 is located at the bottom of the welding chamber 61, and the transmission shaft of the rotary motor 76 passes through the main body 6 and is connected to the outer reversing mechanism 77, so that the two clamping mechanisms 7 can realize synchronous clamping or loosening through a power source. Figure 2 As shown, after two adjacent pipes are placed on the clamping block 75 and butted, the two pipes can be synchronously clamped by starting the rotating motor 76 and then welded, thereby improving the butt-jointing accuracy and welding efficiency.

[0053] At the same time, since the clamping block 75 is detachably connected to the connecting rod 74, the clamping blocks 75 of different sizes can be replaced according to pipes of different diameters and application scenarios.

[0054] At the same time, it can be known that when the special-shaped pipe fitting 9 can be fixed by the clamping assembly 5, the clamping mechanism 7 may not be activated to reduce energy consumption.

[0055] like Figure 2 , Figure 6 , Figure 8 and Fig. 9 As shown, the horizontal welding platform and the vertical welding platform are both provided with a cross bar 12, a vertical bar 11 and a column 13, and the distance between the two cross bars 12 is adapted to the width of the horizontal welding device 3 or the vertical welding device 4, specifically, the horizontal welding device 3 can move between two adjacent cross bars 12 of the horizontal welding platform 1, and the vertical welding device 4 can move between two adjacent cross bars 12 of the vertical welding platform 2.

[0056] At the same time, taking the horizontal welding table 1 as an example, the upper end surfaces of the vertical rod 11 and the horizontal rod 12 are horizontal, which reduces friction and facilitates the sliding adjustment of the special-shaped pipe fittings 9 on the horizontal welding table 1. At the same time, a loading belt and a unloading belt (not shown) are respectively provided on both sides of the horizontal welding table 1. The segmented special-shaped pipe fittings 9 are transported to the horizontal welding table 1 through the loading belt, and the welded special-shaped pipe fittings 9 are output through the unloading belt, which improves the transportation and welding efficiency and can carry out large-scale welding operations.

[0057] like Figure 6 As shown, the crossbar 12 includes a support portion 14 and a clamping portion 15, the support portion 14 is fixed above the clamping portion 15, the end surface of the support portion 14 is horizontal with the end surface of the vertical bar 11, and the cross section of the clamping portion 15 is a symmetrical dovetail structure. The clamping assembly 5 includes a connecting rod clamp 51, a supporting platform 53 and a sliding block 54, the bottom of the connecting rod clamp 51 is provided with a plug-in block 52, the connecting rod clamp 51 is rotatably connected with the plug-in block 52, the plug-in block 52 is a T-shaped structure, the supporting platform 53 is an L-shaped structure, one side of the supporting platform 53 is provided with a slot for inserting the plug-in block 52, the cross section of the slot is a T-shaped structure, the connecting rod clamp 51 is slidably connected with the supporting platform 53 through the plug-in block 52 and the slot; the other side of the supporting platform 53 is connected with the sliding block 54 by bolts, and the sliding block 54 is slidably connected with the clamping portion 15.

[0058] Through the above technical solution, the side of the support platform 53 with the slot is flush with the end faces of the vertical rod 11 and the support portion 14, and the support platform 53 can play a certain supporting role on the special-shaped pipe fitting 9. After the special-shaped pipe fitting 9 is positioned, the connecting rod clamp 51 is rotated so that the clamp head is aligned with the top of the special-shaped pipe fitting 9, and then the handle of the connecting rod assembly is pressed down, and the special-shaped pipe fitting 9 is fixed to the cross bar 12 or the support plate by the clamp head.

[0059] like Figure 2 As shown in A, clamping components 5 are provided on both sides of the clamping portion 15 of the cross bar 12. According to the clamping requirements, multiple clamping components 5 can be provided. The position of the clamping component 5 can be adjusted by a slider 54 to improve the clamping effect.

[0060] like Figure 2 As shown in B, since the connecting rod clamp 51 is rotatably connected to the plug-in block 52 at the bottom, the angle and direction of the connecting rod clamp 51 can be adjusted, which has high flexibility and can improve the application range of the clamping.

[0061] like Figure 2As shown in C, since the other side of the support platform 53 is connected to the slider 54 by bolts, by loosening the bolts, the support platform 53 and the connecting rod clamp 51 can be turned downward, which will not hinder the sliding of the special-shaped pipe 9 on the horizontal welding platform 1. At the same time, the plug-in block 52 is a T-shaped structure, and the cross-section of the slot is also a matching T-shaped structure, so the plug-in block 52 will not be separated from the support platform 53 when it is turned downward.

[0062] like Figure 2 As shown in D, when the clamping assembly 5 is not needed, the plug-in block 52 and the connecting rod clamp 51 can be removed; when the horizontal welding device 3 moves between two adjacent cross bars 12, the support platform 53 can also be removed to avoid interference with the horizontal welding device 3.

[0063] Furthermore, the main body 6 of the vertical welding device 4 is slidably connected to the clamping portion 15 .

[0064] At the same time Figure 5 As shown, the vertical welding device 4 is different from the horizontal welding device 3 in that the vertical welding device 4 is provided with a clamping mechanism 7 only on one side of the main body 6. The vertical welding device 4 is slidably connected through the clamping portion 15 of the cross bar 12, and is limited by the clamping portion 15. Further, a support rod can be provided on the vertical welding table 2, the support rod is located on one side of the cross bar 12, and both ends of the support rod are connected to the vertical rod 11, and the main body 6 of the vertical welding device 4 is supported by the support rod to improve the supporting effect.

[0065] Furthermore, the mounting ring 81 is made of a transparent rigid material.

[0066] Preferably, the mounting ring 81 may be made of a transparent acrylic plate, PETG, transparent ceramics, etc. The position of the welding gun 82 and the docking position of adjacent pipes can be easily observed through the transparent mounting ring 81, and the welding condition can also be observed. At the same time, the mounting ring 81 has certain strength and high temperature resistance to prevent welding slag from burning and damaging the mounting ring 81, and prevent high temperature from deforming the mounting ring 81.

[0067] Furthermore, a roller is provided below the main body 6 of the horizontal welding device 3 .

[0068] Through the above technical solution, the roller horizontal welding device 3 can be easily moved between two adjacent cross bars 12.

[0069] Furthermore, lifting ears are provided on the main bodies 6 of the horizontal welding device 3 and the vertical welding device 4, so as to facilitate lifting and arranging the horizontal welding device 3 and the vertical welding device 4 at any time.

[0070] The specific welding process of the special-shaped pipe fitting 9 is as follows:

[0071] like Figure 6As shown, the third welding section 93, the fourth welding section 94 and the fifth welding section 95 are placed on the horizontal welding table 1, the third welding section 93 and the fourth welding section 94 are inserted into the mounting ring 81 of one horizontal welding device 3, and the fourth welding section 94 and the fifth welding section 95 are inserted into another horizontal welding device 3. At this time, the segmented pipe fittings can be fixed by the clamping mechanism 7 in the horizontal welding device 3, or by adjusting the position of the clamping assembly 5 and clamping and fixing them by the connecting rod clamp 51.

[0072] Specific as Figure 6 As shown in the figure, the fourth welding section 94 is a U-shaped tube, the arc section of the fourth welding section 94 is supported by the support platform 53, and fixed by the connecting rod clamp 51, and the welding ends of the fourth welding section 94 are fixed by the clamping mechanism 7 in the horizontal welding device 3, which can ensure synchronous clamping with the adjacent third welding section 93 and the fifth welding section 95, improve the alignment accuracy, and facilitate subsequent welding. Welding can be performed simultaneously through two horizontal welding devices 3, which improves welding efficiency.

[0073] Then as Figure 2 As shown, after the third welding section 93, the fourth welding section 94 and the fifth welding section 95 are welded, the second welding section 92, the third welding section 93, the fifth welding section 95 and the sixth welding section 96 are placed in another horizontal welding device 3. Since the second welding section 92 and the sixth welding section 96 are arc-shaped tubes, the other side of the second welding section 92 and the sixth welding section 96 rests on the vertical welding table 2. The second welding section 92 and the first welding section 91 are extended into the vertical welding device 4, and the sixth welding device and the seventh welding device are extended into another vertical welding device 4. At this time, all sections of the special-shaped pipe fitting 9 are fixed by the clamping assembly 5, the horizontal welding device 3 and the vertical welding device 4 respectively, and then the special-shaped pipe fitting 9 can be welded by welding.

[0074] The welding of the three-dimensional structured special-shaped pipe fittings 9 can be realized by the horizontal welding table 1 and the vertical welding table 2, which fills the blank of automatic welding of the special-shaped pipe fittings 9, improves the welding efficiency and ensures the welding quality.
