Technical Field

[0001] The utility model belongs to the technical field of electric welding machines, and more specifically relates to a secondary wire connection device for a double-acting electric welding machine. Background Art

[0002] Welding technology is widely used in all walks of life. The secondary wire is the output wire coil of the electric welding machine. When working, it needs to be connected to the weldment to form a current loop. The connection method between the secondary wire and the weldment is generally to wrap the secondary wire around the weldment to achieve connectivity between the two.

[0003] However, in actual on-site work, it is often the case that there is no space for secondary wires to be wound around the components that need to be welded (such as welding a 3m*6m open flat plate). In this case, the secondary wires can only be wound around adjacent equipment, which will cause the secondary wires to be too long and may also cause problems such as arc burns on the equipment.

[0004] In actual work, the connection points of the secondary wires are often severely rusted and stained with oil, resulting in poor contact of the secondary wires, arc breaking, sparking, or even failure to strike an arc.

[0005] Therefore, a welding machine secondary wire connection device is needed to overcome the problems of slow speed, loose connection, many restrictions and so on in the existing secondary wire winding connection method. Utility Model Content

[0028] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0029] like Figure 1 As shown, a secondary wire connection device for a double-acting electric welding machine comprises:

[0030] An insulating frame 1, wherein both ends of the insulating frame 1 are respectively provided with adsorption parts;

[0031] The conductive nozzle 2 is arranged at the center of the insulating frame 1, and the direction of the tip of the conductive nozzle 2 is consistent with the direction of the adsorption end of the adsorption part;

[0032] The elastic mechanism is arranged between the conductive tip 2 and the insulating frame 1, and is used to provide a force to expose the tip of the conductive tip 2 and the adsorption part.

[0033] Specifically, the conductive tip 2 and the adsorption part are supported and connected by the insulating frame 1, and the device is fixed on the welding part by the adsorption part, and then the welding part and the power supply are connected by the conductive tip 2. At the same time, the elastic mechanism continuously provides force to make the conductive tip 2 close to the welding part, so as to avoid the separation of the conductive tip 2 and the welding part due to welding vibration, thereby realizing the replacement of traditional winding wiring and being suitable for large-area welding parts.

[0034] At the same time, the device can be placed as close to the welding area as possible, and is suitable for use on smooth and flat large walls such as cooling towers.

[0035] In this embodiment, the adsorption portion includes an electromagnet 3 or a permanent magnet 4 .

[0036] Specifically, the welding part is an iron part, which can be adsorbed and fixed by the electromagnet 3 or the permanent magnet 4.

[0037] Furthermore, when the electromagnet 3 is used, it can be directly connected to a welding power source through a voltage stabilizing module, a voltage transformation module, etc., or a separate power source can be provided.

[0038] In this embodiment, the elastic mechanism includes:

[0039] The spring sheet 5 and the outer periphery of the conductive nozzle 2 are provided with a blocking ring. The spring sheet 5 is sleeved on the conductive nozzle 2 and is located between the blocking ring and the insulating frame 1.

[0040] Specifically, the spring sheet 5 provides a force to bring the conductive tip 2 close to the welding piece.

[0041] Furthermore, the spring sheet 5 is a highly elastic sheet of metal, and its shape is similar to a bowl with a hole in the middle.

[0042] In this embodiment, the tail end of the conductive tip 2 passes through the insulating frame 1 and is exposed, and an adjusting nut is provided at the exposed end of the conductive tip 2 .

[0043] Specifically, the conductive tip 2 can be conveniently adjusted and replaced by adjusting the nut, and the tail end of the conductive tip 2 is connected to a power source, and the power line can be tightened by adjusting the nut.

[0044] Furthermore, the conductive tip 2 is made of copper alloy or other highly conductive materials, and the overall shape is cylindrical and stepped, with the dimensions from top to bottom being φ10mm, φ14mm, φ24mm, φ14mm, and φ6mm tips. The top φ10mm part of the cylinder has an external thread, which can be assembled with the adjusting nut. When the adjusting nut is tightened, most of the secondary wires will be pressed on the φ14mm step, thereby achieving the connection between the secondary wire of the welding machine and the conductive tip 2. The φ24mm flange is pressed on the spring sheet 5. The φ6mm tip at the front can penetrate rust and oil while meeting the transmission current, thereby ensuring the conductive effect.

[0045] In this embodiment, the conductive tip 2 and the adsorption portion form a mountain-shaped structure.

[0046] Specifically, the tip of the conductive tip 2 is higher than / exposed on the two adsorption parts, so as to avoid the conductive tip 2 being suspended in the air during use. Meanwhile, the conductive tip 2 is located in the middle, so the force stabilization effect is good.

[0047] In this embodiment, the insulating frame 1 includes a bakelite board.

[0048] Specifically, the adsorption part is insulated by using a bakelite board to prevent electricity from being passed to the adsorption part.

[0049] In this embodiment, the permanent magnet 4 includes a magnetic ring and a fastening screw. One end of the fastening screw is provided with an obstruction portion, and the other end of the fastening screw passes through the magnetic ring and is connected to the insulating frame 1.

[0050] Specifically, the magnetic ring is a permanent magnet, which is fixed by fastening screws to facilitate replacement and maintenance.

[0051] Furthermore, a conical obstruction portion is provided at one end of the fastening screw, and the magnetic ring is provided with a coaxial through hole and a guide opening matching the conical obstruction portion, so that the conical obstruction portion is not exposed to the guide opening, thereby ensuring that the magnetic ring is directly adsorbed to the welding part and the adsorption effect is guaranteed.

[0052] In this embodiment, the other end of the fastening screw passes through the insulating frame 1 and is exposed, and a fastening nut is provided at the exposed end of the fastening screw.

[0053] Specifically, the magnetic ring is fixed by fastening nuts and fastening bolts to avoid direct threaded connection between the fastening bolts and the bakelite board, which is not strong enough to meet the service life requirements.

[0054] In this embodiment, the electromagnet 3 includes a coil and a fastening bolt, one end of the fastening bolt is provided with an obstruction portion, and the other end of the fastening bolt passes through the coil and is connected to the insulating frame 1 .

[0055] Specifically, the coil is energized to generate magnetism, and the coil is fixed by tightening bolts to facilitate replacement and maintenance.

[0056] In this embodiment, the connection terminals of the coil pass through the insulating frame 1 and are exposed.

[0057] Specifically, the connection terminals of the coil are kept away from the welding parts to avoid over-lap discharge.

[0058] When a double-acting electric welding machine secondary wire connection device is used in this embodiment, taking the use of an electromagnet 3 and a permanent magnet 4 as an example, a clean area is first cleared during use, and then the permanent magnet 4 is used to adsorb on the welded part, and the position of the conductive tip 2 is adjusted to ensure that the conductive tip 2 can be stably and continuously released from the welded part and then the electromagnet 3 is energized, thereby ensuring that the conductive tip 2 and the welded part are stable during the welding process.

[0059] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
