Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of submerged arc welding technology, and more specifically, to a multi-station automatic submerged arc welding machine. Background Technology
[0002] Submerged arc welding (SAW) machines are large-scale equipment used for automated welding. Their core process is submerged arc welding, which achieves efficient welding by burning an electric arc under a layer of flux. They are suitable for batch processing of long straight welds or circumferential welds and are widely used in pressure vessels, pipelines, ships, and steel structure manufacturing. SAW machines are characterized by no visible arc light during the welding process, less smoke and dust, greater penetration depth, and stable weld quality. They can also achieve high-precision welding through program control. The "submerged arc" in their name comes from the fact that the electric arc is covered by granular flux during welding, forming a protective layer to prevent air contamination of the molten pool. They are key equipment for improving welding efficiency and quality in modern heavy industry.
[0003] In the existing technology, operators often use submerged arc welding machines to perform welding operations. Although existing submerged arc welding machines have basic welding functions, the welding wire spool is usually fixed. This makes it inconvenient for operators to remove and replace the welding wire spool when it is exhausted, which affects the efficiency of the operator in replacing the welding wire, thereby increasing the downtime of the equipment and affecting the working efficiency of the welding machine. Therefore, it is necessary to improve it. Utility Model Content

[0006] As a preferred embodiment of this disclosure, a spring is movably sleeved on the outer surface of the movable rod, the right side of the spring is fixedly connected to the outer surface of the movable rod, and the left side of the spring is fixedly connected to the right side of the fixed plate.
[0007] As a preferred technical solution of this disclosure, a limiting block is fixedly connected to the bottom of the connecting plate, and the outer surface of the limiting block is movably connected to the interior of the movable seat.
[0008] As a preferred technical solution of this disclosure, a first motor is fixedly connected to the right side of the processing table, and a first threaded rod is fixedly sleeved at the other end of the output shaft of the first motor. The other end of the first threaded rod passes through the processing table and extends into the interior of the processing table and is sleeved with the internal thread of the mounting bracket.
[0009] As a preferred technical solution of this disclosure, a limiting rod is fixedly connected to the inner cavity of the processing table, and the outer surface of the limiting rod is movably sleeved with the inner cavity of the mounting frame.
[0010] As a preferred technical solution of this disclosure, a pneumatic cylinder is fixedly connected to the bottom of the inner surface of the mounting bracket, and the top of the pneumatic cylinder is fixedly connected to the bottom end of the movable plate.
[0011] As a preferred technical solution of this disclosure, a second motor is fixedly connected to the front of the movable plate, and a second threaded rod is fixedly sleeved at the other end of the output shaft of the second motor. The other end of the second threaded rod passes through the movable plate and extends into the interior of the movable plate and is sleeved with the internal thread of the movable seat.
[0012] As a preferred technical solution of this disclosure, a welding head body and a flux box are fixedly connected to the left and right sides of the bottom of the movable seat, respectively. A flux tube is fixedly connected to the bottom of the flux box. A drive motor is fixedly connected to the bottom of the inner cavity of the processing table. A rotating shaft is fixedly sleeved at the other end of the output shaft of the drive motor. A rotating rod is fixedly sleeved at the other end of the rotating shaft.
[0013] As a preferred embodiment of this disclosure, sleeve rods are movably connected to both the left and right sides of the outer surface of the rotating rod, and a connecting rod is fixedly connected to the outer side of the sleeve rods.

[0015] The beneficial effects of the embodiments disclosed herein are as follows:
[0016] 1. This disclosure incorporates a fixed plate, a movable rod, a moving block, a diagonal rod, and a connecting plate. When the movable rod is pressed, the moving block overcomes the spring force and moves horizontally to the left under the limiting action of the fixed plate. This causes the diagonal rod to move, which in turn presses and pushes the connecting plate. The connecting plate then drives the limiting block to move horizontally forward under the limiting action of the movable seat. Ultimately, this causes the welding wire reel to detach from the interior of the connecting plate, facilitating the replacement of the welding wire reel, improving the efficiency of the operator in replacing the welding wire reel, and reducing equipment downtime.
[0017] 2. This disclosure incorporates a rotating rod, sleeve rod, connecting rod, baffle, and clamping plate. When the drive motor starts running, the rotating shaft drives the rotating rod to rotate, causing the rotating rod to press and push the sleeve rods on both sides. This causes the sleeve rods to drive the connecting rod and baffle to move horizontally towards each other under the limiting action of the top plate. Finally, through the opposite movement of the six clamping plates, the device achieves the effect of fixing workpieces of different sizes at multiple workstations, thus improving its applicability.

[0025] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.
[0026] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."
[0027] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.
[0028] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0031] like Figures 1-5 As shown, a multi-station automatic submerged arc welding machine according to an embodiment of the present disclosure is illustrated, including a processing table 1, a mounting frame 2 movably connected inside the processing table 1, a movable plate 17 movably connected inside the top of the mounting frame 2, a movable seat 3 movably connected inside the movable plate 17, a fixed plate 4 fixedly connected to the top of the movable seat 3, a movable rod 5 movably sleeved inside the fixed plate 4, the left end of the movable rod 5 penetrating through the fixed plate 4 and extending into the interior of the fixed plate 4 and fixedly connected to a moving block 6, a diagonal rod 7 hinged to the outer surface of the moving block 6, a connecting plate 8 hinged to the other end of the diagonal rod 7, a vertical plate 10 located on the back of the connecting plate 8 fixedly connected to the top of the movable seat 3, a welding wire spool 11 movably sleeved inside the connecting plate 8 and the vertical plate 10, and the bottom of the connecting plate 8 movably connected to the top of the movable seat 3.
[0032] When the movable rod 5 is pressed, the moving block 6 will move horizontally to the left under the limiting action of the fixed plate 4, thereby causing the inclined rod 7 to move and press and push the connecting plate 8, causing the connecting plate 8 to move forward, and finally causing the welding wire spool 11 to disengage from the interior of the connecting plate 8, thus realizing the function of facilitating the replacement of the welding wire spool 11.
[0033] In some examples, a spring 9 is movably sleeved on the outer surface of the movable rod 5, with the right side of the spring 9 fixedly connected to the outer surface of the movable rod 5 and the left side of the spring 9 fixedly connected to the right side of the fixed plate 4.
[0034] Due to the design of spring 9, the moving block 6 has a good reset effect during subsequent movement, thereby ensuring that the connecting plate 8 always fixes the welding wire spool 11.
[0035] In some examples, the bottom of the connecting plate 8 is fixedly connected to a limiting block 12, and the outer surface of the limiting block 12 is movably connected to the interior of the movable seat 3.
[0036] Due to the limiting effect of the movable seat 3, the connecting plate 8 can only move horizontally back and forth along the limiting block 12.
[0037] In some examples, a first motor 13 is fixedly connected to the right side of the processing table 1, and a first threaded rod 14 is fixedly sleeved at the other end of the output shaft of the first motor 13. The other end of the first threaded rod 14 passes through the processing table 1 and extends into the interior of the processing table 1 and is sleeved with the internal thread of the mounting bracket 2.
[0038] When the first motor 13 starts running, it will cause the first threaded rod 14 to rotate, thereby allowing the mounting bracket 2 to move horizontally left and right under the limiting action of the processing table 1.
[0039] In some examples, the inner cavity of the processing table 1 is fixedly connected to a limit rod 15, and the outer surface of the limit rod 15 is movably sleeved with the inner cavity of the mounting frame 2.
[0040] Due to the limiting effect of the limiting rod 15, the mounting bracket 2 moves horizontally left and right along the inside of the processing table 1.
[0041] In some examples, a pneumatic cylinder 16 is fixedly connected to the bottom of the inner surface of the mounting bracket 2, and the top of the pneumatic cylinder 16 is fixedly connected to the bottom of the movable plate 17.
[0042] When the pneumatic cylinder 16 starts running, it will cause the movable plate 17 to move vertically up and down under the limiting action of the mounting bracket 2.
[0043] In some examples, a second motor 18 is fixedly connected to the front of the movable plate 17, and a second threaded rod 19 is fixedly sleeved at the other end of the output shaft of the second motor 18. The other end of the second threaded rod 19 passes through the movable plate 17 and extends into the interior of the movable plate 17 and is threadedly sleeved with the interior of the movable seat 3.
[0044] When the second motor 18 starts running, it will cause the second threaded rod 19 to rotate, thereby allowing the movable seat 3 to move horizontally back and forth under the limiting action of the movable plate 17.
[0045] In some examples, the welding head body 28 and the flux box 29 are fixedly connected to the left and right sides of the bottom of the movable seat 3, respectively. The flux tube 30 is fixedly connected to the bottom of the flux box 29. The drive motor 20 is fixedly connected to the bottom of the inner cavity of the processing table 1. The other end of the output shaft of the drive motor 20 is fixedly sleeved with a rotating shaft 21. The other end of the rotating shaft 21 is fixedly sleeved with a rotating rod 22.
[0046] When the drive motor 20 starts running, it will cause the rotating shaft 21 to drive the rotating rod 22 to rotate.
[0047] In some examples, sleeve rods 23 are movably connected to both the left and right sides of the outer surface of the rotating rod 22, and a connecting rod 24 is fixedly connected to the outside of the sleeve rods 23.
[0048] When the rotating rod 22 rotates, it will press and push the sleeve rods 23 on both sides, causing the sleeve rods 23 to drive the connecting rod 24 to move closer to the drive motor 20.
[0049] In some examples, a top plate 26 is fixedly connected to the top of the inner cavity of the processing table 1, a baffle 25 is movably connected to the inner surface of the top plate 26, the bottom of the baffle 25 is fixedly connected to the top of the connecting rod 24, a clamping plate 27 is fixedly connected to the top of the baffle 25, and the bottom of the clamping plate 27 is movably connected to the top of the top plate 26.
[0050] The design of the baffle 25 prevents welding slag from falling into the inner cavity of the processing table 1 during subsequent welding processes.
[0051] The working principle and usage process of this disclosure are as follows:
[0052] Multiple workpieces are placed between six clamping plates 27, and three drive motors 20 are started in sequence. At this time, the rotating shaft 21 drives the rotating rod 22 to rotate, which causes the rotating rod 22 to squeeze and push the sleeve rods 23 on both sides. The sleeve rods 23 drive the connecting rod 24 and the baffle 25 to move horizontally towards each other under the limiting action of the top plate 26. Finally, through the opposite movement of the six clamping plates 27, the fixing effect of workpieces of different sizes is achieved in multiple positions, which improves the applicability of the device. After the fixing is completed, the welding head body 28 moves to the top of the designated welding position through the coordinated movement of the first motor 13 and the second motor 18. Then, the pneumatic cylinder 16 is started, which causes the welding head body 28 to move downward and perform welding operation.
[0053] When the welding wire wound on the welding wire reel 11 is exhausted and needs to be replaced, pressing the movable rod 5 will cause the moving block 6 to overcome the elastic force of the spring 9 and move horizontally to the left under the limiting action of the fixed plate 4. This will cause the inclined rod 7 to move and squeeze and push the connecting plate 8. The connecting plate 8 will drive the limiting block 12 to move horizontally forward under the limiting action of the movable seat 3. Finally, the welding wire reel 11 will be disengaged from the interior of the connecting plate 8, realizing the function of easy replacement of the welding wire reel 11, improving the efficiency of operators in replacing the welding wire reel 11, and reducing the downtime of the equipment.
[0054] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
