Abstract
Description
Technical Field
[0001] This utility model relates to the field of rotary welding equipment technology, and in particular to a grounding conductive device for welding. Background Technology
[0002] When using a high-power welding machine, the negative terminal of the welding machine needs to be connected to the workpiece, and the positive terminal to the welding torch. The workpiece also needs to be grounded. However, for rotating circumferential welds, some grounding conductive devices require high precision in workpiece surface machining. Poor contact with the workpiece can easily lead to electrolytic corrosion, and the conductive device generates significant heat, reducing the conductivity of the conductive shaft and compromising the stability of the welding current. This affects the internal quality of the weld and can easily cause the cable to become entangled and damaged. Current grounding methods fix the grounding wire to one side of the weldment. When the weldment needs to be rotated, this can lead to entanglement and damage to the wire, or poor conductive contact, affecting the weld quality. Utility Model Content
[0003] To overcome the shortcomings of existing technologies, a grounding conductive device for welding is proposed to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:
[0005] A grounding conductive device for welding includes a fixed base, a base connecting block fixedly disposed on the middle of one side of the fixed base, a grounding connecting rod fixedly connected to the base connecting block, a grounding wire connecting terminal sleeved on the grounding connecting rod, a fixing nut disposed on the side of the grounding wire connecting terminal away from the fixed base, and the fixing nut being threadedly connected to the grounding connecting rod.
[0006] As a further technical solution of this utility model: two grounding wire connection terminals are provided.
[0007] As a further technical solution of this utility model: the number of fixing nuts is two.
[0008] As a further technical solution of this utility model: the grounding wire connection terminal is provided with a mounting hole.
[0009] The beneficial effects of this utility model are:
[0010] This utility model features a fixed base with a grounding connecting rod, on which a grounding wire connecting terminal is looped. The fixed base is mounted on a rotating shaft. The welding current is conducted through the fixed base and the grounding connecting rod to the grounding wire connecting terminal, which is then connected to the grounding wire. This directs any leakage current, static charge, and lightning current that may occur on the equipment to the ground, thus preventing electric shock and potential accidents such as fires and explosions. It also avoids direct connection between the grounding wire and the welded parts, which could affect the welding quality. Attached Figure Description
