Abstract
Description
Technical Field
[0001] This utility model relates to the field of power maintenance technology, specifically a magnetic suction multifunctional electric welding grounding device. Background Technology
[0002] In existing technologies, welding machines are widely used in welding operations due to their ease of operation and convenience. To ensure the safety of workers, the welding machine's grounding wire must first be grounded. Currently, the grounding method involves connecting one end of the grounding wire to the welding machine's grounding interface and wrapping the other end around the anchor bolts of other equipment. This current method presents the following problems:
[0003] (1) The grounding wire is easily not firmly connected when it is wrapped around the anchor bolts of other equipment. The grounding wire is prone to expansion and loosening when heated, resulting in poor grounding contact, unstable welding current, and quality problems such as slag and porosity at the weld. Construction workers need to rework and re-weld, which seriously affects the welding quality and construction efficiency.
[0004] (2) When the grounding wire of the welder is connected to the anchor bolts of other equipment, the equipment becomes a conductor. After the equipment becomes conductive, it will generate heat. The sensitivity of the precision parts in the equipment will decrease or even fail after heating, which can easily cause damage to the equipment.
[0005] (3) Commonly used alligator clips or lap joints with added iron blocks will have poor contact, high resistance, easy to spark, generate high temperature, and may even cause the metal at the joint to melt and connect into one piece, which poses a serious safety hazard.
[0006] (4) When welding small parts, the workers need to hold the parts directly with their hands or other tools to weld them. This can easily cause the parts to shift and loosen. The workers need to rework and re-weld, which seriously affects the welding quality and construction efficiency. Moreover, it can easily cause burns to the workers and poses a serious safety hazard.
[0007] To address the aforementioned shortcomings in the existing technology, this utility model aims to provide a multi-functional magnetic grounding device for electric welding. Utility Model Content
[0008] The purpose of this utility model is to provide a magnetic suction type multifunctional electric welding ground device to address the above-mentioned shortcomings.
[0009] The technical solution of this utility model is: a magnetic suction type multifunctional electric welding grounding device, which includes two parts: an insulating grounding device and an auxiliary welding device.
[0010] The insulating grounding device has an insulating plate installed on top of a powerful magnet. A conductive rod is installed on the side of the insulating plate away from the powerful magnet. The conductive rod passes through the insulating plate and has a spring installed inside. The grounding wire is fixed by a cable clamping nut and threadedly connected to the conductive rod. There is a fixed support on the upper surface of the insulating plate.
[0011] The auxiliary welding device includes a counterweight, a sliding device on the counterweight, a locking device on the sliding device, a workpiece fixing rod that passes through the sliding device, and the counterweight connected to a fixed support on an insulating plate via a support rod.
[0012] The bottom end of the conductive rod is pointed.
[0013] The workpiece fixing rod is L-shaped, and the contact end between the workpiece fixing rod and the welded workpiece is pointed.
[0014] The advantages of this invention are: 1. By using an insulating plate to separate the ground wire from the powerful magnet, the heating of the powerful magnet is prevented, allowing it to adhere well to the workpiece and completely eliminating poor contact, thus ensuring welding quality and construction efficiency. 2. The powerful magnet can be attached to any position on the workpiece and can be moved freely, facilitating manual and flexible installation and removal of the ground wire. 3. The conductive rod is made of copper, which significantly improves the conductivity between the grounding wire and the workpiece. 4. The auxiliary welding device can easily fix the workpiece within a certain range for welding work, avoiding direct contact between operators and welding sparks, thus ensuring worker safety.
[0015] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0020] See Figure 1 , 23. A magnetic suction type multifunctional electric welding grounding device, comprising two parts: an insulating grounding device and an auxiliary welding device.
[0021] An insulating grounding device consists of an insulating plate 1 mounted on top of a powerful magnet 2. A conductive rod 3, made of copper and with a pointed bottom, is positioned on the side of the insulating plate 1 away from the powerful magnet 2. The conductive rod 3 penetrates the insulating plate 2 and contains a spring 5 to ensure good conductivity of the workpiece being welded. The grounding wire is secured by a cable clamping nut 4 and threadedly connected to the conductive rod 3. The powerful magnet 2 is then attached to the workpiece, and the pointed end of the conductive rod 3 contacts the workpiece for welding.
[0022] The auxiliary welding device includes a support rod 7, a counterweight 8, a sliding device 9, a locking device 10, and a component fixing rod 11. The counterweight 8, sliding device 9, and locking device 10 are installed together. The auxiliary welding device is connected to the insulating grounding device, i.e., connected to the insulating plate 1, through the support rod 7 and the fixed support 6. The length of the workpiece fixing rod 11 can be freely adjusted by inserting it into the sliding device 9. During welding, the workpiece is fixed by its own weight and the counterweight 8. The tip of the workpiece fixing rod 11 presses against the workpiece. The auxiliary welding device can also be used independently without being connected to the grounding device. This utility model is applicable to the installation and use of grounding wires for all electric welding machines, avoiding problems such as electric sparks and high temperatures caused by poor contact of the grounding wire, eliminating safety hazards, avoiding direct manual welding by operators, ensuring welding quality and construction efficiency, and protecting the safety of workers.
