Abstract
The utility model relates to a magnetic ground connector for an arc welder connecting to the earth, which is composed of a permanent magnetic ferrite (3), a flux plate (4) and a handle (2). The utility model is characterized in that the magnetic ground connector not only has strong attraction force to ferromagnetic materials to cause the arc welder to have favorable earth contact performance on-stream, but also has a degaussing mechanism; the strong attraction force of the magnetic ground device vanishes away as the position of the handle is adjusted after the work, and the welded object can be easily taken off. The utility model, which is an ideal grounding device, has the advantages of wide range of application and long service life.
Description
The utility model is a kind of magnetic grounding device that is used for electric welding machine ground connection.
The electric welding machine grounding device is in the existing production application of countries such as Britain, West Germany.Domestic also have similar imitation products now, and its structure is shown in accompanying drawing 7,8.This grounding device is because magnetic field suction is big, be difficult for taking off from the welded article body, in addition because it produces very strong magnetic field all the time on magnetic conductive board, therefore when not working, especially often adsorb a lot of welding slag, iron filings, make troubles in the relatively poor place of operational environment, applied certain difficulty at present at home to the user.
The purpose of this utility model is: design a kind of magnetic grounding device with demagnetization mechanism.
Accompanying drawing 1 is that place of the present utility model sees vertical view.
Accompanying drawing 2 is outward appearance front views of the present utility model.
Accompanying drawing 3 is structural front view of the present utility model.
Accompanying drawing 4 is that structure A-A of the present utility model is to cutaway view.
Accompanying drawing 5 is operating state schematic diagrams of the present utility model.
Accompanying drawing 6 is non operating state schematic diagrams of the present utility model.
Accompanying drawing 7 is prior art constructions vertical views.
Accompanying drawing 8 is prior art constructions front views.
The utility model is to realize like this, it mainly is made up of permanent-magnet ferrite (3), magnetic conductive board (4) and handle (2), it is characterized in that: non-magnetic dividing plate (8) is housed on the magnetic conductive board (4), turning handle (2) can make magnetic earthing device present two states, during work, turning handle (2) makes permanent-magnet ferrite (3) contact with magnetic conductive board (4), produces high-intensity magnetic field at magnetic conductive board, holds tightly welded object. When not working, go back to handle (2) at this moment permanent-magnet ferrite (3) and magnetic conductive board throw off fully, non-magnetic dividing plate (8) disconnects its magnetic circuit every therebetween. With on magnetic conductive board guard shield (9) cover, make magnetic conductive board (4) form magnet short-cut path after hours, eliminate induced field, guard shield (9) also plays protection magnetic conductive board (4), makes magnetic conductive board be difficult for being damaged by collision.
The utility model makes the magnetic grounding device have two kinds of operating states owing to be provided with demagnetization mechanism, and is easy to operate.It has that ground connection is reliable, easy to clean, advantage such as not fragile, is a comparatively ideal earthing device.
Below be specific embodiment of the utility model, but the utility model is not limit by this example.
Shown in accompanying drawing 1-4, the magnetic grounding device is connected the electric welding machine ground wire with screw (1) with handle (2), handle (2) should be selected conduction, non-magnet_conductible material for use, this example is selected alloy aluminum for use, when handle (2) was in position shown in the accompanying drawing 4, permanent-magnet ferrite (3) contacted with magnetic conductive board (4), and at this moment magnetic conductive board (4) is gone up and produced a high-intensity magnetic field that is not less than 20 kilograms of suction, hold the welded article body tightly, make it reliable ground.Magnetic conductive board (4) is the common carbon steel A that selects for use
3Stainless steel rivet (5) rivets together magnetic conductive board (4) and handle (2), when the needs demagnetization, handle (2) is to be the axle center with rivet (5), going to alignment pin (6) locates, at this moment, permanent-magnet ferrite (3) is thrown off fully with magnetic conductive board (4), and high-intensity magnetic field disappears thereupon, the magnetic grounding device can take off from the welded article body very like a cork.Screw (7) is contained in non-magnetic conduction dividing plate (8) on the magnetic conductive board (4).This example of non-magnetic conduction dividing plate (8) selects for use engineering plastics to manufacture.Work finishes, on guard shield (9) cover, as shown in Figure 2.Guard shield (9) can be selected commaterial for use with magnetic conductive board (4).
Claims (2)
1, magnetic grounding device, by permanent-magnet ferrite (3), magnetic conductive board (4), and handle (2) composition is characterized in that:
On a, the magnetic conductive board (4) non-magnetic conduction dividing plate (8) is housed;
B, magnetic conductive board have a guard shield (9) outward;
C, handle (2) are rotating.
2, magnetic grounding device according to claim 1 is characterized in that: when guard shield (9) covered on the magnetic conductive board (4), magnetic conductive board (4) formed magnet short-cut path.
