Disclosure of Invention
In order to overcome the defects of the prior art, the invention aims to provide the air blowing anti-splashing electrode so as to eliminate the hidden troubles of poor quality of high-strength plates and hot-forming plates during nut welding.
In order to realize the aim, the upper conical rod of the upper electrode of the utility model is connected with the upper holding rod of the spot welding machine, the air pipe interface of the upper electrode is connected with the air pipe joint of the air pipe body, and the air pipe body interface is connected with the upper air pipe of the spot welding machine; the cylindrical boss at the lower part of the positioning pin is connected with the upper flat end of the spring, and the lower flat end of the spring is connected with the bottom end of the electrode holder; the external thread end of the lower electrode is in threaded connection with the internal thread end of the electrode seat; the lower conical rod of the electrode seat is connected with the lower holding rod of the spot welding machine.
And a channel for welding slag to pass through is arranged in the upper electrode and is connected with the air pipe connector.
The taper of the upper conical rod of the upper electrode is consistent with that of the upper holding rod taper hole, and the upper conical rod is connected with the upper holding rod taper hole in a matched mode.
The taper of the lower conical rod of the electrode base is consistent with the taper of the lower holding rod taper hole, and the lower conical rod is connected with the lower holding rod taper hole in a matched mode.
The spring penetrates through the concentric inner holes in the lower electrode and the electrode holder.
Compared with the prior art, the utility model, the accessible increases inside interface and the passageway of blowing at last electrode, blow in the twinkling of an eye welding circular telegram, the air current passes through inside the nut screw thread from the nut upper surface, the splashing that produces in the twinkling of an eye the welding blows off from the nut lower surface, blow off from the inside passageway of last electrode, can eliminate the splashing that the projection welding produced in the twinkling of an eye and fall into the downthehole defect such as trafficability characteristic that causes of nut screw, the welding that leads to because of there being welding slag in the nut is avoided bad, can effectively reduce because of the bad cost of selecting of reprocessing that causes of welding part trafficability, reduce intensity of labour and manufacturing cost, improve production efficiency and welding quality.
