Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a linear welding device with an auxiliary structure. Background Technology

[0002] In the field of guardrail welding manufacturing, traditional welding processes generally adopt a single welding gun point-by-point welding method, that is, operators or welding equipment weld each connection point of the guardrail in sequence. However, with the significant increase in the demand for guardrail production, the single welding gun welding method results in low welding efficiency and limited production capacity. In the existing technology, if a single welding gun is used for point-by-point welding in guardrail welding operations, there are problems of low efficiency and poor consistency. At the same time, when moving and adjusting multiple welding guns, the wiring of the connecting welding guns lacks organization and arrangement, which makes multiple wirings easy to get tangled together.

[0003] For example, the authorized patent document with application number CN202223317695.5 discloses a linear welding device that effectively solves the problem that the lack of fixed clamping of the workpieces to be welded easily leads to a large gap between the two workpieces, resulting in poor welding effect. The device includes a worktable, with support legs installed at the four corners of the bottom end of the worktable, a clamping assembly installed at the top end of the worktable, a welding assembly installed at the top end of the worktable, and a movable seat movably provided on the side. The top end of the fixed seat and the top end of the movable seat are both equipped with clamping units, and the bottom end of the movable seat is equipped with a moving part.

[0004] The aforementioned patents employ a single welding torch for point-to-point welding, resulting in low welding efficiency and limited production capacity. Therefore, we need to provide a linear welding device with an auxiliary structure. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a linear welding device with an auxiliary structure, comprising:

[0026] Platform 1, welding assembly 2 and placement rack. Platform 1 is equipped with a placement rack on top to limit the metal plates to be welded. Platform 1 is equipped with a welding assembly 2 on top to perform synchronous welding operations on the metal plates in the placement rack.

[0027] Specifically, a welding assembly 2 is provided at the top of platform 1, where multiple welding guns work simultaneously, enabling the welding of multiple weld points at once, reducing the time spent on repetitive positioning and single-point welding.

[0028] The welding assembly 2 includes a floating platform 21, a welding torch body 22, a cable 23, and a moving component 24. The top of the platform 1 is provided with a moving component 24 for the synchronous movement of the four welding torch bodies 22. All four welding torch bodies 22 are located inside the floating platform 21, and the top of each of the four welding torch bodies 22 is provided with a cable 23.

[0029] Furthermore, a moving component 24 is set to adjust the movement of the floating platform 21, and all four welding gun bodies 22 are mounted on the floating platform 21 to achieve synchronous movement adjustment of the four welding gun bodies 22. Multiple welding guns work simultaneously, which can complete the welding of multiple weld points at one time, reducing the time for repeated positioning and single-point welding. This is suitable for mass production of guardrails and significantly improves production capacity. The multiple welding guns use uniform welding parameters (current, voltage, wire feed speed) to ensure that the penetration depth and weld width of each weld point are uniform and consistent. This is especially suitable for thin-walled steel pipes. The distribution of the four welding gun bodies 22 is suitable for the joint between short and long metal plates.

[0030] The moving component 24 includes a frame 241, a drive component 200, a slide 242, and a cylinder 243. The frame 241 is fixedly installed on the top of the platform 1. The slide 242 is slidably installed on the surface of the frame 241. The bottom of the slide 242 is provided with a cylinder 243. The extended end of the cylinder 243 is installed on the top of the floating platform 21. The drive component 200 is used to drive the slide 242 to move.

[0031] It is worth noting that the movement of the slide 242 is achieved by the drive component 200, the top of the cylinder 243 is fixedly installed at the bottom of the slide 242, and the lower end of the cylinder 243 is located at the top of the floating platform 21. By activating the cylinder 243, the height of the floating platform 21 can be adjusted, thereby controlling the height adjustment of the welding torch body 22. The drive component 200 is installed on the surface of the frame 241, and the slide 242 also slides on the frame 241.

[0032] The driving component 200 includes a driving rod 201, a protective cover 202 and a motor 203. The top of the frame 241 is provided with a protective cover 202. The driving rod 201 is rotatably installed inside the protective cover 202. One end of the driving rod 201 is provided with a motor 203, and the surface of the driving rod 201 is threadedly engaged with the slide block 242.

[0033] It should be noted that the starting motor 203 drives the drive rod 201 to rotate, and the surface of the drive rod 201 is threaded onto the slide 242, thereby driving the slide 242 to slide within the frame 241, which in turn drives the linear movement of the four welding torch bodies 22. The drive rod 201 is located inside the protective cover 202, which protects the drive rod 201. Furthermore, four balls are embedded in the top of the inner wall of the slide 242, and the balls slide within the guide groove at the top of the frame 241, reducing friction as the slide 242 moves.

[0034] It also includes a sorting component 4 for arranging four cables 23. The sorting component 4 includes a slide table 41 and a storage cylinder 42. The slide table 41 is slidably mounted on the top of the protective cover 202. The top of the slide table 41 is provided with a storage cylinder 42 for the four cables 23 to be placed together. The storage cylinder 42 has an open area on one side.

[0035] Furthermore, the tops of the four cables 23 all pass through the slide table 41 and enter the storage cylinder 42, and are discharged through the opening at one end of the storage cylinder 42. The storage cylinder 42 plays a role in collecting the four cables 23 in a centralized manner, preventing the cables 23 from being scattered.

[0036] The bottom of the slide table 41 is provided with four pulleys 5, and the top of the protective cover 202 is provided with two slide rails 6 for the sliding of the pulleys 5;

[0037] The slide table 41 has four pulleys 5 at its bottom. When the slide table 41 moves, the pulleys 5 will slide within the slide rail 6, reducing friction on the movement of the slide table 41.

[0038] Two synchronization components 7 are provided between the slide table 41 and the floating table 21. The synchronization component 7 includes a sleeve 71 and a slide rod 72. The top of the sleeve 71 is fixedly installed on the surface of the slide table 41, and the slide rod 72 is slidably installed inside the sleeve 71. The lower end of the slide rod 72 is fixedly installed on the top of the floating table 21.

[0039] It is worth noting that when the cylinder 243 drives the floating platform 21 to move, the height adjustment of the floating platform 21 will cause the slide rod 72 to slide inside the sleeve 71, so that the slide 41 follows the movement of the floating platform 21, and the slide 41 is driven to move by the synchronizing component 7.

[0040] The display rack includes a display table 8 and a contact table 9. The top of the platform 1 is provided with a display table 8 for placing multiple short metal plates, and the contact table 9 is used to attach two long metal plates to multiple short metal plates.

[0041] Specifically, multiple display stands 8 are distributed on the top of platform 1 for placing short metal plates, while two contact stands 9 are used for placing two long metal plates and also serve to bring the two metal plates closer to the multiple short metal plates.

[0042] The contact platform 9 includes a frame 91, a double threaded rod 92, a contact block 93, and a protective cover 94. Both frames 91 are embedded in the platform 1. The two contact blocks 93 are threadedly installed on both sides of the surface of the double threaded rod 92. The frame 91 is provided with a protective cover 94 for protecting the double threaded rod 92.

[0043] Two long metal plates are placed on two frames 91. Each of the two double-threaded rods 92 has a handwheel at one end. By rotating the handwheel, the double-threaded rods 92 are rotated, thereby controlling the two abutting blocks 93 inside the frame 91 to move closer to each other. The two abutting blocks 93 push the two long metal plates together and fit against multiple short metal plates to achieve positioning, which facilitates subsequent welding operations. At the same time, a protective cover 94 is set on the top of the double-threaded rods 92 to prevent debris from accumulating on the surface of the double-threaded rods 92.

[0044] The welding torch body 22, cylinder 243 and motor 203 involved in this application are all implemented using existing mature technologies, which are conventional technical means in this field. Therefore, their specific circuit connections, control logic and working processes will not be described in detail.

[0045] This device places two long metal plates on two frames 91. Each of the two double-threaded rods 92 has a handwheel at one end. By rotating the handwheel, the double-threaded rods 92 rotate, thereby controlling the two abutment blocks 93 inside the frame 91 to move closer to each other. The two abutment blocks 93 push the two long metal plates together and fit against multiple short metal plates to achieve positioning. The motor 203 is started to drive the drive rod 201 to rotate. The surface of the drive rod 201 is threaded with the slide 242, thereby driving the slide 242 to slide within the frame 241, which in turn drives the linear movement of the four welding torch bodies 22. By starting the cylinder 243, the height of the floating table 21 can be adjusted, thereby controlling the height adjustment of the welding torch bodies 22 and causing the four welding torch bodies 22 to move downward to weld the short metal plates and the long metal plates.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
