Description

Technical Field

[0001] The utility model belongs to the technical field of welding equipment, and particularly relates to a welding machine ground wire fixing tool. Background Art

[0002] A grounding wire is required during welding. Grounding is a preliminary work that must be done before using a welding machine. As the most widely used electrical safety measure, grounding wire refers to the neutral point of the power system and electrical equipment, the exposed conductive parts of the electrical equipment and the conductive parts outside the device connected to the earth through a conductor; the grounding wire is a line directly connected to the earth, which can also be called a safety return line. When it is dangerous, it transfers high voltage directly to the earth, which is considered a lifeline; the traditional way of grounding is to fix the ground wire directly to the product with electric welding. This operation method will leave welding marks, which are commonly known as "welding marks". "Welding flaws" will affect the appearance of the product. When the electric welder is finished working, it is necessary to manually remove the ground wire welded on the product and manually remove the "welding flaws", which is time-consuming and laborious. Moreover, the electric welder needs to be changed from time to time, and the connection points of the ground wire also need to be constantly changed. In this way, the number of "welding flaws" left behind will increase, and the workload of personnel will also increase. This welding method is inconvenient to change the position, resulting in low work efficiency of personnel. At the same time, this direct grounding method will also affect the safety of the welding machine during use and affect the appearance of the product. Utility Model Content

Before using the clamp 1 to clamp, pre-connect one end of the ground wire to the ground wire connecting component 2, insert the clamping ring 25 into the bolt, and place it between the upper pressure ring 22 and the lower pressure ring 23. Then, rotate the second butterfly head bolt 21 to drive the upper pressure ring 22 to approach the lower pressure ring 23, and press the clamping ring 25 to the lower pressure ring 23 to complete the fixation of the ground wire; then, put the clamping plate 12 in the clamp 1 on the rectangular steel plate, and drive the extrusion plate 14 to squeeze toward one side of the rectangular steel plate by rotating the first butterfly head bolt 11 until the first butterfly head bolt 11 can no longer rotate, and the clamping work is completed. If the welding object is a steel pipe, whether to use the auxiliary plate 3 of the clamp for assistance is determined according to the diameter of the steel pipe. If the diameter of the steel pipe is similar to the length of the first vertical plate 122 and the second vertical plate 123, the auxiliary plate 3 of the clamp is not required, and the first solution is directly adopted; if the diameter of the steel pipe is much smaller than the length of the first vertical plate 122 and the second vertical plate 123, the auxiliary plate 3 of the clamp is used together with the extrusion plate 14, and the transmission bolt 33 in the rectangular shell 32 is rotated to make the upper clamp plate 34 and the lower clamp plate 35 both stick to the steel pipe, and the steel pipe is squeezed together with the extrusion plate 14 to complete the fixation of the clamp; the above are all solutions taken for the safety of welding machine use.
