Description

Technical Field

[0001] This utility model relates to the field of welding machine wire winding technology, specifically a welding machine wire rotation and folding device that prevents the wire from being dragged on the ground. Background Technology

[0002] The welding process requires a large current to generate sufficient heat to melt the welding rod and the workpiece. Therefore, welding machine wires need to have good conductivity and a large current-carrying capacity to ensure stable current transmission and prevent the wire from overheating, being damaged, or even causing safety accidents due to excessive current. This necessitates the use of multi-strand copper wires or other highly conductive metal materials to form the conductor, thereby increasing the cross-sectional area of ​​the wire and improving its current-carrying capacity.

[0003] During welding operations, dragging welding machine cables on the ground can easily cause various safety problems. Firstly, the dragging cable may be stepped on or run over by passing personnel or equipment, leading to damage to the insulation layer and potentially causing electrical leakage, threatening personnel safety.7 Secondly, dragging cables makes the construction site cluttered, increasing the risk of workers tripping and falling.7 Cable-free devices can suspend the cables off the ground, effectively avoiding these safety hazards.

[0004] The device will be in a relatively fixed position, making it difficult to move flexibly according to changes in the welding position. Welders may need to frequently move the welding machine body to align with the welding point, which not only increases labor intensity but may also cause excessive pulling on the power cord and welding cable of the welding machine, affecting their service life and even causing circuit failures.

[0005] To address the aforementioned issues, a rotating and foldable device for welding machine cables that prevents them from being dragged on the ground is proposed. Utility Model Content

[0032] 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.

[0033] To further understand the contents of this utility model, a detailed description of this utility model will be provided with reference to the accompanying drawings.

[0034] Reference Figures 1-5 This utility model discloses a rotating and foldable device for welding machine wires that does not drag on the ground, including a mounting base 1 as a basic support component, and a fixing base 2 fixedly connected to the bottom left side of the mounting base 1 to provide an installation position for subsequent components.

[0035] A first motor 11 is fixedly connected to the middle right side of the fixed base 2. A lead screw 13 is fixedly connected to the output end of the first motor 11. A nut pair 14 is threadedly connected to the outer ring of the lead screw 13 on its right side. A movable base 15 is fixedly connected to the right side of the nut pair 14. Guide posts 12 are slidably connected through the interior of both the front and rear ends of the movable base 15. The guide posts 12 are fixedly connected to the fixed base 2, which makes the movable base 15 more stable during movement and provides a good guiding function.

[0036] A connecting column 16 is fixedly connected to the right side of the movable seat 15, and a sliding seat 3 is fixedly connected to the right side of the connecting column 16. The sliding seat 3 is slidably connected to the bottom of the mounting seat 1, so that when the first motor 11 drives the lead screw 13 to rotate, the sliding seat 3 can slide horizontally at the bottom of the mounting seat 1.

[0037] The bottom of the sliding seat 3 is fixedly connected to the second motor 17. The output end of the second motor 17 is fixedly connected to the connecting plate 5. The top of the connecting plate 5 is rotatably connected to the rotating sleeve 4. The rotating sleeve 4 is fixedly connected to the sliding seat 3, thereby realizing the rotation of the connecting plate 5 relative to the rotating sleeve 4, which in turn drives the connecting frame 6 fixedly connected to the bottom of the connecting plate 5 and other components on the connecting frame 6 to rotate.

[0038] The bottom of the connecting frame 6 is rotatably connected to the rotating frame 8. The inside of the connecting frame 6 is rotatably connected to the take-up roller 7. The take-up roller 7 is fitted with a connecting line 9. The inside of the take-up roller 7 is rotatably connected to the rotating shaft 18. Torsion springs 19 are fitted on the outer rings of both the left and right sides of the rotating shaft 18. The winding and unwinding operations of the connecting line 9 are realized through the torsion springs 19.

[0039] One end of the rotating frame 8 is fixedly connected to the limiting seat 10, and one end of the limiting seat 10 is provided with a protective component. The protective component includes a fixing sleeve 21, which is fixedly connected to one end of the limiting seat 10. One end of the fixing sleeve 21 is fixedly connected to the first connecting frame 22, and a connecting rod 25 is fixedly connected to the left side of the first connecting frame 22. The rotating frame 31 rotates, so that the rotating frame 31 is slidably connected to the connecting line 9, which can be used for line winding. At the same time, the rotating frame 31 is composed of two rotating rods, and the connecting end can rotate.

[0040] The left side of the connecting rod 25 is fixedly connected to the second connecting frame 23, and one end of the bottom connecting rod 25 is fixedly connected to the third motor 24. The connecting rods 25 are internally rotatably connected to a rotating shaft 27, and the rotating shafts 27 are rotatably connected to a universal joint 26 to ensure flexible rotation. The outer ring of the rotating shaft 27 is fixedly connected to a gear 28, and the outer ring of the gear 28 meshes with a rack 29. Evenly distributed guide blocks 30 are fixedly connected to the outer right wall of the second connecting frame 23, and the guide blocks 30 are slidably connected to the rack 29. One end of the rack 29 is fixedly connected to a limiting block 20. This series of structures constitutes the impurity cleaning mechanism.

[0041] In actual operation, when the horizontal position of the device needs to be adjusted, the first motor 11 is started. The first motor 11 drives the lead screw 13 to rotate, and the nut assembly 14 moves left and right on the lead screw 13, causing the moving seat 15, connecting column 16, sliding seat 3 and other components to slide horizontally at the bottom of the mounting base 1, thereby adjusting the horizontal position of the device. To achieve the rotation function of the device, the second motor 17 is started. The second motor 17 drives the connecting plate 5 to rotate, and the connecting plate 5 drives the connecting frame 6, winding roller 7, rotating frame 8, limit seat 10 and other components to rotate around the axis of the rotating sleeve 4, meeting the needs of adjusting the device angle in different working scenarios. During the use of the welding machine, when it is necessary to wind up the connecting wire 9, the torsion spring 19 inside the winding roller 7 plays a role, gradually winding up the connecting wire 9; when it is necessary to unwind the connecting wire 9, the operator pulls the connecting wire 9 outward to overcome the torque of the torsion spring 19, thereby releasing the connecting wire 9 and driving the rotating frame 8 to rotate, in order to adapt to different welding working distance requirements. During winding, the third motor 24 is started, which drives the connecting rod 25 at the bottom to rotate. The rotating shaft 27 on the connecting rod 25 rotates accordingly, and the gear 28 on the rotating shaft 27 rotates. The rack 29 meshing with the gear 28 moves linearly under the guidance of the guide block 30, thereby driving the limit block 20 to move. The limit block 20 cleans the impurities adhering to the line and prevents them from entering the winding roller 7.

[0042] Working principle: When the horizontal position of the device needs to be adjusted, the first motor 11 is started. The first motor 11 drives the lead screw 13 to rotate. Since the lead screw 13 is threadedly connected to the nut pair 14, and the moving seat 15 is fixedly connected to the nut pair 14, and the moving seat 15 is guided and restricted by the guide column 12, the nut pair 14 will move left and right on the lead screw 13, thereby driving the moving seat 15, connecting column 16, sliding seat 3 and other components to slide horizontally at the bottom of the mounting base 1, realizing the horizontal position adjustment of the device. To realize the rotation function of the device, the second motor 17 is started. The second motor 17 drives the connecting plate 5 to rotate. The top of the connecting plate 5 is rotatably connected to the rotating sleeve 4, and the rotating sleeve 4 is fixed to the sliding seat 3, so the connecting plate 5 will rotate relative to the rotating sleeve 4, thereby driving the connecting frame 6, winding roller 7, rotating frame 8, limit seat 10 and other components to rotate around the axis of the rotating sleeve 4, meeting the needs of adjusting the device angle in different working scenarios. When the connecting wire 9 needs to be wound up during the use of the welding machine, the torsion spring 19 inside the winding roller 7 plays a role. A torsion spring 19 is fitted onto the rotating shaft 18. Under the torque of the torsion spring 19, the take-up roller 7 gradually winds up the connecting wire 9. When it is necessary to unwind the connecting wire 9, the operator pulls the connecting wire 9 outward to overcome the torque of the torsion spring 19, thus releasing the connecting wire 9 and driving the rotating frame 8 to rotate to adapt to different welding working distance requirements. During winding, the third motor 24 is started. The third motor 24 drives the bottom connecting rod 25 to rotate, and the rotating shaft 27 on the connecting rod 25 rotates accordingly. Since the rotating shafts 27 are connected by universal joints 26, the flexibility of rotation is ensured. The gear 28 on the rotating shaft 27 rotates with the rotating shaft 27, and the rack 29 meshing with the gear 28 moves linearly under the guidance of the guide block 30, thereby driving the limit block 20 to move. The limit block 20 cleans the impurities adhering to the line, preventing them from entering the take-up roller 7 and improving its service life.
