Abstract
The utility model discloses a projection welding plate electrode, which comprises an electrode plate. The electrode plate is provided with a first electrode hole, a second electrode hole and a third electrode hole from top to bottom, the first electrode hole, the second electrode hole and the third electrode hole are concentric holes, aperture of the first electrode hole is larger than that of the second electrode hole, aperture of the second electrode hole is larger than that of the third electrode hole, and the electrode plate is further provided with a vertical water inlet hole and a vertical water outlet hole both communicated with a horizontal water passage hole. Distributary poor welding of a projecting welding nut is eliminated for the projection welding plate, oil and gas are collectively discharged from the electrode hole during welding, number of repair and replacement of the electrode is also reduced, defectiveness and increased cost of a concentric insulated secondary positioning pin are avoided during positioning, high-efficiency welding is realized, and the projection welding plate electrode has the advantages of simple structure and convenience in use.
Description
Technical field
The utility model relates to a kind of electrode, relates in particular to a kind of projection welding plate electrode.
Background technology
At present, project-welding nut is with the concentric secondary alignment pin of tape insulation in the middle of the circular rod electrode, nut is being pressed weldment, another outer face filled circles bar electrode pressurization energising realizes the fixing and welding of nut and weldment, alignment pin is in using with special cermacis, broken easily the replacing frequently, and productivity ratio is low, another kind of applied powder metallurgy insulation alloy alignment pin no longer insulate after wearing and tearing in the application and produces the phenomenon of project-welding nut rosin joint; The third is bad to be that present nut and weldment punching press cleaning agent and oily extensive use exempt to clean welding, and the oil gas collection in the welding of generation is stayed the surface of circular rod electrode, its electric conductivity is descended and cleaning frequent; The 4th kind bad be the filled circles bar electrode after the welding some, boss in the load mould occurs and contact conduction with the nut inner hole screw thread and generation rosin joint quality occurs shunting.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of projection welding plate electrode, this projection welding plate electrode has been eliminated project-welding nut shunting rosin joint, oil gas in the welding process is concentrated and is discharged from electrode hole, that has reduced electrode reprocesses and changes number of times, a concentric locating of electrode, the cost of having got rid of the bad of insulation concentric secondary alignment pin in the location and having increased, realize efficient welding, had characteristics simple in structure, easy to use.
In order to achieve the above object, the technical solution adopted in the utility model is:
A kind of projection welding plate electrode, comprise battery lead plate 7, first electrode hole 1, second electrode hole 2 and third electrode hole 3 are arranged on the battery lead plate 7 from top to bottom successively, first electrode hole 1, second electrode hole 2 and third electrode hole 3 are concentric holes, and the aperture of first electrode hole 1 is greater than the aperture of second electrode hole 2, and the aperture of second electrode hole 2 is greater than the aperture in third electrode hole 3.
Also have vertical inlet opening 4 and apopore 5 on the described battery lead plate 7, inlet opening 4 and apopore 5 all communicate with the limbers 6 of level.
The utility model compared with prior art has the following advantages:
1) eliminated project-welding nut shunting rosin joint.
2) oil gas in the welding process is concentrated and to be discharged from electrode hole, and that has reduced electrode reprocesses and change number of times.
3) get rid of the bad and cost that increases of the concentric secondary alignment pin of insulation in the location, realized efficient welding.
Description of drawings
Fig. 1 is a cross-sectional view of the present utility model.
Fig. 2 is a cross-sectional view of the present utility model.
Fig. 3 is a perspective view of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of projection welding plate electrode, comprise battery lead plate 7, first electrode hole 1, second electrode hole 2 and third electrode hole 3 are arranged on the battery lead plate 7 from top to bottom successively, first electrode hole 1, second electrode hole 2 and third electrode hole 3 are concentric holes, and the aperture of first electrode hole 1 is greater than the aperture of second electrode hole 2, and the aperture of second electrode hole 2 is greater than the aperture in third electrode hole 3.Also have vertical inlet opening 4 and apopore 5 on the battery lead plate 7, inlet opening 4 and apopore 5 all communicate with the limbers 6 of level.
Operation principle of the present utility model is:
Project-welding nut is put into the electrode hole 2 of projection welding plate electrode, weldment is inserted the common location of screw pushed down behind the electrode hole 1 of projection welding plate electrode on project-welding nut and the projection welding plate electrode and fixing.Realize the welding assembling by weldment and project-welding nut being applied electric current, the oil gas residue that produces in the welding process is discharged from electrode hole 3; The inlet opening of reserving 4 can add water in the limbers 6, welding process is done simple constant temperature handle, and the two ends of limbers 6 can be stopped up.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; everyly any simple modification that above embodiment did, change and equivalent structure are changed, all still belong to the protection domain of technical solutions of the utility model according to the utility model technical spirit.
