Magnetic type earth wire connecting device of electric welder

Abstract

The invention discloses a magnetic type earth wire connecting device of an electric welder. The device comprises an earth wire cable (1) and a magnet (2), wherein the magnet (2) is arranged inside a sealed shell; the shell is composed of an upper shell (3), a lower shell (4) and an electrode shell (5); the electrode shell (5) is connected with the earth cable (1) and the electrode shell (5) can be absorbed on a weldment through the magnet (2) inside the shell; the upper shell (3), the lower shell (4) and the electrode shell (5) all have no magnetism and cannot be magnetized; and the height of an inner cavity of the shell formed by the upper shell (3), the lower shell (4) and the electrode shell (5) is higher than the height of the magnet (2), so that the magnet (2) can reciprocate up and down inside the shell. With the adoption of the connecting device, the impurity can be prevented from being absorbed on the electrode shell prior to welding, so that the quality and the efficiency of the welding are improved; and the connecting device has the characteristics of smart design, simple structure and good reliability, and is convenient to operate.

Description

technical field [0001] The invention relates to a magnetic suction type ground wire connection device for an electric welding machine, which is used for connecting the ground wire of the electric welding machine to a weldment. Background technique [0002] At present, the connection of the ground wire electrode in the use of electric welding machine is very inconvenient. There are two existing ground wire electrode connection methods: the first one is to bolt the ground wire cable directly to the weldment. Although this is very convenient, it often generates arcs and has many potential safety hazards. Necessary loss, and it is easy to cause safety accidents such as fire; the second method: use magnetic force, use the suction force of the magnet to firmly adsorb the ground wire electrode on the weldment, this connection method is firm and reliable, simple and convenient to use, and saves It saves time and effort, while improving work efficiency, no arc will be generated, and...

[0002] At present, the connection of the ground wire electrode in the use of electric welding machine is very inconvenient

There are two existing ground wire electrode connection methods: the first one is to bolt the ground wire cable directly to the weldment. Although this is very convenient, it often generates arcs and has many potential safety hazards. Necessary loss, and it is easy to cause safety accidents such as fire; the second method: use magnetic force, use the suction force of the magnet to firmly adsorb the ground wire electrode on the weldment, this connection method is firm and reliable, simple and convenient to use, and saves Save time and effort, while improving work efficiency, no arc will be generated, and cables will no longer be burned, energy saving and environmental protection

However, the magnets of the existing magnetic adsorption connection devices are all exposed, which brings a fatal shortcoming: in the actual use environment, there are many impurities such as welding slag that are easily absorbed by the magnet, and these impurities are easily adsorbed on the connection device. It will seriously affect the quality and efficiency of welding
