Abstract
Th utility model relates to an earthing device for electric welder negative electrode electric welding handle wire for electric welding operation. The utility model is composed of a copper nut (1), a conductive fixing copper connecting rod (3), a permanent magnet outer protective shell (4), a strong permanent magnet (5) and an earthing body (6). The utility model has the advantages of simple structure, easy manufacture, convenience and practicability. The utility model can ensure that the earthing body and welding workpieces are fixedly and reliably lapped and electric welding construction operation is smoothly carried out.
Description
The utility model relates to a kind of electric welding machine negative electricity electrode holder line bonding device that is used for electric welding field.
Electric welding is the most basic operation in industrial and agricultural production, the plant equipment installation, maintenance work.The electric welder need adopt negative pole to make line bonding device electric welding machine bonding ground connection to guarantee handling safety during electric welding field.At present, normally used electric welding machine negative electricity electrode holder line bonding device is difficult for fixing, loose contact when workpiece has iron rust, and construction operation is very inconvenient.
The purpose of this utility model is to provide a kind of construction operation of being convenient to, and can remove the surface of the work iron rust, guarantees the reliable electric welding machine negative electricity of electric weld handle line bonding electrode holder line magnetic bonding device.
The utility model is to realize like this.This kind attachment for welding cable is made up of copper nut, conduction fixed copper connecting rod, permanent magnet outer protecting shell, powerful permanent iron, bonding body, its structure and assembling feature are as follows: conduction fixed copper small end is equipped with copper nut by screw thread, the bottom is set with powerful permanent iron and places the permanent magnet outer protecting shell, and bonding body upper end is screwed in the screw of connecting rod lower end by screw thread.During use, electric weld handle line copper sleeve is placed conduction fixed copper connecting rod step top, tighten copper nut and tighten electric weld handle line copper sleeve fixing.Then bonding body lower end is placed on the surface of the work.Because the overlap joint body has strong magnetic force under the effect of powerful permanent iron, thereby can adsorb the surface that is overlapped on welded part securely, the electric welder can begin weld job.After welding finishes, the electric welder can be at an easy rate with attachment for welding cable with take after welding work pieces separates.
The utility model is simple in structure, is easy to make, and is convenient and practical, and it is solid and reliable to utilize it can guarantee that bonding body and welding work pieces overlap, and guarantees carrying out smoothly of electric welding construction operation.
Accompanying drawing is the utility model general structure schematic diagram.Among the figure, label " 2 " is an electric weld handle line copper sleeve.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of copper nut 1, conduction fixed copper connecting rod 3, permanent magnet outer protecting shell 4, powerful permanent iron 5 and overlap joint body 6.Wherein, copper connecting rod 3 is the copper round bar that a middle and upper part is provided with six side's steps, and its upper end has the pin thread that matches with copper nut 1, and the center, lower end is provided with for bonding body 6 upper ends and screws in the screw that connects usefulness.Permanent magnet outer protecting shell 4 is the no round-ended cylinder shape housing of an end face center band circular hole.Powerful permanent iron 5 is a hollow cylinder magnet, and its inside and outside disc matches with connecting rod 3 external diameters and protective case 4 internal diameters respectively.Bonding body 6 is the tower shape, the top is provided with the pin thread that matches with connecting rod 3 lower end screws, middle part face of cylinder diameter and permanent magnet 5 inner headed faces match, bottom round platform diameter is consistent with protective case 4 external diameters, the side's of being with flat face is cut in both sides, the face of cylinder, bottom, so that its upper end is played spanner when being screwed into the connecting rod screw, the bottom surface be "
" font and make pitted skin, can be in order to remove non-conductive materials such as surface of the work iron rust.
Claims (3)
