Embodiment 1

[0025] This embodiment provides a CO 2 Welding machine automatic grounding device, please refer to figure 1 with figure 2 , the CO 2 The automatic grounding device of the welding machine includes: a base 1, a conductive copper plate 2, a spring 3 and a copper wire row 4, and the base 1 is used for installing other components of the device. The spring 3 is arranged on the base 1, and the conductive copper plate 2 is arranged on the spring 3, that is, the lower end of the spring 3 abuts against the upper surface of the base 1, and the upper end of the spring 3 withstands the lower end surface of the conductive copper plate 2, so that the conductive copper plate 2 It can move up and down along with the expansion and contraction of the spring 3. Both ends of the copper wire row 4 are respectively connected to the conductive copper plate 2 and the base 1 , thus forming a path between the base 1 and the conductive copper plate 2 . Preferably, the first end of the copper wire ro...

Embodiment 2

[0032] The embodiment of the present invention provides a CO 2 Welding machine automatic grounding device, please refer to Figure 1 to Figure 4 , this embodiment reflects the working state of the device. The CO 2 The automatic grounding device 10 of the welding machine is installed on the corresponding fixed bracket of the roller bed used by the base bolt 7, and the CO 2 The negative ground wire of the input terminal of the welding machine is connected to the base 1 through the base bolt 7, and the CO 2 The automatic grounding device 10 of the welding machine is installed at the lower end of the adjustment line conveying roller bed, and the upper surface of the conductive copper plate 2 is slightly higher than the conveying roller of the roller bed. Like this, when the slide skid 8 that is loaded with body-in-white advances, slide skid 8 front parts and CO 2 The automatic grounding device 10 of the welding machine contacts and forms a welding circuit, because in this CO ...

Abstract

The invention discloses a carbon dioxide (CO2) welding machine automatic grounding device and belongs to the technical field of CO2 shielded welding machine welding. The CO2 welding machine automatic grounding device comprises a base (1),a conductive copper plate (2), a spring (3) and a copper wire row (4), wherein the spring (3) is arranged on the base (1), the conductive copper plate (2) is arranged on the spring (3), the conductive copper plate (2) can move up and down along with stretching out and drawing back of the spring (3), and two ends of the copper wire row (4) are respectively connected with the conductive copper plate (2) and the base (1). According to the CO2 welding machine automatic grounding device, through the arrangement of the CO2 welding machine automatic grounding device, the layout of the connection mode of grounding of a CO2 welding machine is more scientific and reasonable, operation procedures of a welder is simplified, the quality of grounding is guaranteed, the co-ordination among different types of work in a station is greatly improved, working efficiency and product quality are improved, besides, the CO2 welding machine automatic grounding device is simple in structure, convenient to use, low in cost, and strong in practicability.

Description

technical field [0001] The present invention relates to CO 2 The field of gas shielded welding welding technology, in particular to a CO 2 Automatic grounding device for welding machine. Background technique [0002] CO 2 The welding machine is based on CO 2 As a shielding gas metal arc welding equipment, a gas protective layer is formed around the arc during operation to isolate the external oxygen and prevent the weld from being oxidized and carbonized, thereby improving the quality of the weld and making the welding plane more beautiful and smooth. Mainly used in heavy machinery manufacturing industries, such as locomotives, automobile manufacturing, shipbuilding, power generation equipment manufacturing and other component processing industries. CO 2 Gas shielded welding is a high-efficiency welding method, with CO 2 The gas is used as the shielding gas, and the gas shielded welding method that relies on the arc of the welding wire and the welding machine to melt t...
