Abstract
The utility model relates to a connector for welded articles and welded grounding wires, which can be used in various welding procedures. The connector is composed of an inverted U-shaped shell body which is opened at three faces and is provided with a guiding groove at the two side surfaces, a copper conducting block which can slide in the shell body from top to bottom, a spiral pressurizing mechanism, a magnetic suction disk on the base plate at the lower part of the shell body, etc. The connector has the advantages of convenient operation, labor saving and enhanced work efficiency, and is especially suitable for the occasions that the welded workpiece is enormous, and the edge portion of the welded workpiece is far apart from a welded mouth and is not suitable to use welded grounding wire clamps.
Description
The utility model belongs to mechanical engineering field, and specifically, it relates to the coupling arrangement between welding ground cable and the welded piece.Can be widely used in the various welding procedures, be applicable to connecting between welded piece with plane or garden curved surface of column surface configuration and the welding ground cable, be particularly useful for pipeline butt welding construction.
Known welding ground cable and the coupling method between the welded piece have following four kinds of methods usually:
One, directly the exposed end of welding ground cable is pressed under the welded piece, but, tends to make cable and welded piece to break away from and make to weld and interrupt as bumping cable because of carelessness.Though this method is simple, and is unreliable.
Two, the welding ground cable is fastened on the welded piece with screw, but the screw that when changing welded piece, need change the outfit again.Though this method is reliable, complicated operation is time-consuming, influences operating efficiency.
Three, clamp clamping welded piece, the welding ground cable with the rigidity jaw is fastened on the clamp handle with screw.But often only be point between rigidity jaw and the welded piece, wire contacts, and chucking power is less, is easy to come off.
Four, with the clamp clamping welded piece of elasticity moving jaw, the welding ground cable is fastened on the clamp handle with screw.(consult utility model patent: the welding ground clamp.Application number 91200042.2).Can obtain reliable clamping by easy operation, realize connecting between welded piece and the welding ground cable.But this clamp is only not too huge at welded piece, near weld bond, has the edge to use under the situation for clamping on the welded piece.But it is huge at welded piece, the weldment edge is when weld bond is far away, for example more than 10 meters in the tube butt welding construction, clamp can only be clamped in pipe and not weld on the end edge of an end, so, huge welding current must flow through whole body could form the loop, the heat that has a resistance on welded piece so, its consumed power is P=I
2R is directly proportional with current squaring, and is directly proportional with effective resistance value, and this is a kind of meaningless electric energy loss; In addition, the welder need walk about long apart from removing the clamp that installs or removes before welding and after the welding, inconvenience is arranged more.
The purpose of this utility model is the above-mentioned shortcoming that overcomes the welding ground clamp, make the welder just need not walk about in the welding place can be very simply, easily the welding ground cable connection to the position of the close weld bond of welded piece, with avoid welding current on welded piece by producing too much resistive heat losses and avoid the welder to load and unload the physical demands that clamp is walked up and down apart from long.
For reaching this purpose, the utility model does not adopt clamping or bolt connection mode on the connecting mode of welding ground cable and welded piece, it is characterized in that adopting magnetic suction disc (2), conducting block (3) and screw press mechanism (6).This coupling is securely fixed on any position on iron and steel weldment surface, guarantees contact well between welding ground cable and the welded piece.Accompanying drawing is the utility model structural representation.This coupling is by the inverted U-shaped housing (1) of three openings, is fixed on the magnetic suction disc (2) on the lower housing portion chassis, be contained in housing (1) inside, the copper contact conducting block (3) that can slide up and down along housing (1) side gathering sill, and be fixed on the pressurization screw rod (6) of housing (1) top nut (7) and can dial the screw press mechanism that the crank (9) that gets off formed from screw rod (6) end of pressurizeing and form by screw-in.Pressurization screw rod (6) and slidably make resilient connection with compressing spring (8) between the conducting block (3).The upper end of spring (8) is pressed under the pad (11) of the stop screw (10) that is fixed in pressurization screw rod (6) and below thereof.The part that spring (8) top endoporus is stretched in pressurization screw rod (6) lower end play the guiding role to spring (8).The part that compression spring (8) below endoporus is stretched in the upper end that is installed in the bolt (5) of sliding conduction piece (3) upper surface also play the guiding role to compression spring (8).The positive central authorities of conducting block (3) are drilled with the horizontal direction blind hole, can insert welding ground cable exposure end.The top and the bottom end face central authorities of conducting block (3) all have vertical direction to connect screw, the top screw screws in spring guide blot (5), and the below screw screws in the bolt (12) of not appearing, and compresses the cable exposure end that is inserted by horizontal blind hole.Four stop screws (4) are equipped with in the two sides of conducting block (3), in the gathering sill that per two group is set on housing (1) two sides, guarantee that conducting block (3) can only translation up and down in housing (1).Conducting block (3) upper surface is plane, and the lower surface is garden curved surface of column shape, and conducting block (3) can mate the use of turning upside down by screw (4) and different screw, to be adapted to the surface configuration of different welded pieces.Pressurization screw rod (6) upper end is square, be complementary with the square hole of crank (9) end, by inserting or transfering to, the connection that can realize the two with separate.
An embodiment of the present utility model is as follows:
At the welded piece surface configuration, the surface configuration of selected conducting block (3) lower surface is corresponding with it, installs coupling by accompanying drawing.The exposed end of welding ground cable is inserted in the blind hole of the positive central authorities of conducting block (3), and tighten fastening bolt (12) the cable exposure end is pressed on the inwall of the horizontal blind hole of conducting block (3).Processing of rust removing is good on the aligning welded piece of the lower surface of conducting block (3), prepare to install the position of coupling, slightly firmly push, magnetic suction disc (2) is contacted with the welded piece surface, whole coupling is just inhaled on the welded piece surface securely together with the welding ground cable.Should note making conducting block central authorities blind hole direction this moment down.Good in order to guarantee that conducting block (3) contacts with the welded piece surface, need conducting block (3) is pressurizeed.Crank (9) is enclosed within pressurization screw rod (6) end, and clockwise direction shakes crank (9), and pressurization screw rod (6) is moved down, and spring (8) is compressed, and conducting block (3) is pressurizeed.When contact spring guide blot (5) upper end is just wanted in pressurization screw rod (6) bottom, connect pressure and reach maximum.Stop to shake, take off crank (9).Promptly finish the installment work of coupling this moment.Can begin welding.When shaking crank, spring (8) drives conducting block (3) slight jitter, and the slight relative friction of generation between conducting block (3) lower surface and the welded piece surface helps the good contact between the two.
When welding finishes, in the time of need taking off coupling, put crank (9), continue smooth pin and shake crank (9).Pressurization screw rod (6) bottom with become rigid attachment after spring guide blot (5) upper end contacts, promotion conducting block (3) moves down, and backs down magnetic suction disc (2), can take off coupling.
