Description

Technical Field

[0001] The utility model relates to a magnetic electric welding grounding device used in electric welding of steel parts, belonging to the technical field of welding. Background Art

[0002] Electric welding is a common welding method. It requires electric welding machines, welding wires, loop lines, welding torches and other equipment and tools. The specific welding process is: tie the loop line directly to the workpiece or use an object to press the loop line on the workpiece, and then turn on the electric welding machine for welding. This operation method often causes the loop line and the workpiece to be connected in a virtual connection, resulting in sparks at the connection between the loop line and the workpiece, which not only affects the welding quality of the workpiece, causing waste of welding rods and workpieces, but also forces the welding operation to be suspended. The operator has to reconnect the loop line before welding can be resumed, which greatly reduces work efficiency. Therefore, it is very necessary to design and manufacture a high-reliability electric welding grounding device. Utility Model Content

[0021] The utility model aims at the drawbacks of the prior art and provides a magnetic welding grounding device. The use of the grounding device can reduce the labor intensity of workers, improve work efficiency and ensure the welding quality of workpieces.

[0022] See also Figure 1-Figure 7 The utility model comprises a magnet 1, a mounting frame 4, an insulating plate 2, a limit nut 3, a locking nut 5, a circuit line clip 6, a conductive bolt 7 and a spring 8.

[0023] The upper end of the mounting frame 4 is a stud 4-1, and the lower end is a ring 4-2. A connecting seat 4-3 is provided at the bottom of the ring 4-2, and a threaded hole 4-4 is provided on the connecting seat 4-3. The magnet 1 is cylindrical and adsorbed on the workpiece 10. A stepped through hole 1-1 is provided in the middle of the magnet 1, which is fixed to the bottom of the mounting frame 4 by a connecting bolt matching the threaded hole 4-4. The insulating plate 2 is a rectangular plate. The stud 4-1 at the upper end of the mounting frame 4 passes through the through hole at one end of the insulating plate 2 and is screwed into the limit nut 3 to fasten the insulating plate 2 to the mounting frame 4.

[0024] The lower end of the conductive bolt 7 is provided with a contact head 7-1, and the upper end slides through the spring 8 and the through hole at the other end of the insulating plate 2 in sequence, and then two locking nuts 5 and a circuit line clip 6 sandwiched between the two locking nuts 5 are installed. The two locking nuts 5 lock the circuit line clip 6 on the upper end of the conductive bolt 7. The upper surface of the insulating plate 2 rests on the locking nuts 5, and the two ends of the spring 8 are respectively pressed against the contact head 7-1 and the insulating plate 2. By pressing the contact head 7-1, the conductive bolt 7 can slide relative to the insulating plate 2, and the spring 8 is compressed at the same time. After the contact head 7-1 is released, the elastic force of the spring 8 pushes the conductive bolt 7 back to the top and resets it. The circuit line clip 6 is connected to the circuit line 9.

[0026] Install the welding circuit line 9 on the circuit line clip 6, and lock the circuit line clip 6 with the locking nut 5, place the utility model on the workpiece 10, and adsorb the magnet 1 on the workpiece 10, so that the contact head 7-1 at the lower end of the conductive bolt 7 is against the workpiece 10, and the spring 8 is compressed. At this time, the elastic force of the spring 8 makes the conductive bolt 7 and the workpiece 10 in good contact, and then turn on the electric welding machine for welding.
