Abstract

A magnetic earthing electrode of the utility model belongs to a contact electrode for welding. The utility model is composed of a frame (1) made of the non-magnetic conductive metallic material, a wire connecting handle (6) integrating the frame (1) together, a permanent magnet (3) arranged in the frame (1), two iron plates fixed to surfaces of both sides of the frame (1) by screws, etc. When the utility model is used, the utility model is connected to the earthing wire of an electric welder, and the utility model is attached to the welded workpiece. Owing to the magnetic force action, the utility model can be firmly attached. The utility model has not only convenient operation but also favorable electrical contact.

Description

The magnetic grounding electrode

The utility model belongs to a kind of electrical installation, particularly a kind of contact electrode that connects electric welding machine ground wire and workpiece.

When welding, the ground wire and the welded part of electric welding machine is connected together with connecting wire, to constitute the loop of electricity.Because this connection is provisional, promptly at any time wants mobile earth wire, generally adopts to connect an iron block on the ground wire of electric welding machine, this iron block is contacted with welded piece, such as riding over or being placed on the welded part again.Such grounding electrode is difficult to be fixed on the soldered workpiece, because contact is insecure, shift position or disengaging welded piece bring inconvenience to weld job easily, when the weld job of high-altitude, more are difficult to have good electrical contact especially.

The purpose of this utility model is to use the magnetic grounding electrode, makes electric welding machine ground wire and welded part good electrical contact be arranged, convenient working

The utility model is made of the framework of non-magnetic conductive metal material, two iron plates and permanent magnet, have on the framework and connect wiring hole or the binding post that lead is used, permanent magnet is loaded in the framework, two iron plates are placed on respectively on two sides of framework and with permanent magnet and are sandwiched between two iron plates, be that permanent magnet places in the space that framework and two iron plates surround, with screw or rivet two iron plates are fixed on the framework, constitute an integral body.

A kind of structure is wherein provided by Fig. 1 to Fig. 3

Fig. 1 is overall appearance figure of the present utility model.

Fig. 2 is that of the present utility model facing partly cutd open figure.

Fig. 3 is a side cutaway view of the present utility model, i.e. the A-A profile of Fig. 2

As seen from the figure, framework 1 is the square frame that has wiring handle 6, and the two is to have a wiring hole 4 on the whole wiring handle 6, is used for the cross-under lead, with the ground wire electricity connection mutually of electric welding machine.Also can on wiring handle 6, connect a binding post, be used to the lead of twisting joint, with the ground wire electricity connection mutually of electric welding machine.Square permanent magnet 3 is housed in framework 1, and two magnetic pole planes of permanent magnet 3 are parallel with two side surfaces of framework 1 respectively.Two side surfaces at framework 1 are equipped with iron plate 2, are fixed on the framework 1 with screw 5.

Framework 1 is by non-magnetic conductive metal material.Permanent magnet 3 can be a rare earth permanent-magnetic material, also can be ferritic.Two magnetic poles are relative with two iron plates 2 respectively.The space that the shape of permanent magnet 3 and framework 1 and iron plate 2 surround preferably matches, and magnetic pole preferably is close on two iron plates 2.So that when the magnetic grounding electrode is adsorbed on the workpiece, inner magnetic circuit is the crack continuously.The flat shape of iron plate 2 is preferably identical with the two sides shape of framework 1, so that outward appearance is neat.

Characteristics of the present utility model are simple in structurely easy to usely can be made into different sizes and various face shaping according to actual service conditions.During use this magnetic grounding electrode is connected with lead with the electric welding machine ground wire, it is adsorbed on can be owing to magneticaction on the welded part, absorption more at will is not shifted and breaks away from workpiece, and convenient working, particularly when work high above the ground, analogy welding iron tower, magnetic grounding electrode just can be inhaled easily on iron tower and not come off.

Claims
