Description
Technical field
The utility model relates to weld car project-welding nut and double-screw bolt field, relates in particular to a kind of novel projection welding bottom electrode.
Background technology
At present, the be welded project-welding nut and the projection welding double-screw bolt in workshop need use dissimilar projection welding bottom electrodes.When the employee switches to the projection welding double-screw bolt from project-welding nut, need dismantle the projection welding bottom electrode of project-welding nut and replace with the projection welding bottom electrode that corresponding projection welding double-screw bolt is used from projection welder.The spanner of the unspecial dismounting projection welding in workshop bottom electrode, regular switching can cause projection welding electrode and projection welder fixedly the projection welding bottom electrode cooperate not tight, gapped, cause projection welding bottom electrode sealing to be leaked, reduced the intensity of project-welding nut or double-screw bolt, expend more process time simultaneously, reduce operating efficiency, thereby can cause the increase of Workshop Production cost.
The utility model content
The utility model designed a kind of projection welding bottom electrode, solved switch projection welding electrode that the projection welding bottom electrode causes and projection welder fixedly the projection welding bottom electrode cooperate tight and sealing is leaked and expended problem such as process time.
In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:
A kind of projection welding bottom electrode comprises nut fixed mechanism, insulation sleeve, nut projection welding platform and projection welding bottom electrode shell, and described nut fixed mechanism is detachable.
Further, described nut projection welding platform is installed in the projection welding bottom electrode shell, and nut projection welding platform has a centre bore, is used to install insulation sleeve and nut fixed mechanism.
Further, the projection welding bottom electrode can be used for project-welding nut and can be used for the projection welding double-screw bolt again.
Further, after described nut fixed mechanism dismounting, the screw thread position that can put into double-screw bolt in the centre bore of nut projection welding platform is used for the projection welding double-screw bolt.
This projection welding bottom electrode has following beneficial effect:
(1) the utility model projection welding bottom electrode effectively reduces the frequency that the employee changes the projection welding bottom electrode aborning, has reduced the fixedly wearing and tearing at projection welding bottom electrode position of projection welder;
(2) the utility model project-welding nut and projection welding double-screw bolt use different parts at the projection welding bottom electrode, have increased the service life of single projection welding bottom electrode, have reduced the production cost in workshop;
(3) the projection welding bottom electrode of the utility model design is lightly simple, and the practicality height has improved production efficiency, has reduced the production cost in workshop.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further:
As depicted in figs. 1 and 2, a kind of novel projection welding bottom electrode, comprise nut fixed mechanism 201, insulation sleeve 202, nut projection welding platform 203 and projection welding bottom electrode shell 204, wherein nut projection welding platform 203 is installed in the projection welding bottom electrode shell 204, nut projection welding platform 203 has a centre bore, be used to install insulation sleeve 202 and nut fixed mechanism 201, the nut fixed mechanism 201 of projection welding electrode is detachable; Projection welding bottom electrode 304 can be used for project-welding nut can be used for the projection welding double-screw bolt again; After described nut fixed mechanism 201 dismountings, projection welding bottom electrode 304 newels are the cavity, and the screw thread position that can put into double-screw bolt is used for the projection welding double-screw bolt.
The nut projection welding mainly is divided into 4 processes: precompressed (Fig. 3), the welding (Fig. 4), keep (Fig. 5) and stop (Fig. 6).Project-welding nut 302 is placed on projection welding bottom electrode 304 to be had on the alignment pin 307 of spring, plays a part to correct project-welding nut 302 and welding plate 303 positions in welding process.The parameter of projection welding generally is high electric current, the short time.Operation principle is that the heat release by electric current and resistance itself is melted metal in the very short time, and project-welding nut 302 and welding plate 303 are welded.The thickness of projection welding plate 303 is big more, and the electric current that needs is just high more.In the precompressed process, projection welding top electrode 301 closely is connected project-welding nut 302 with welding plate 303 under the effect of cylinder pressure.Fig. 3 is that four nut boss 306 of project-welding nut 302 are fitted with the welding plate 303 that needs processing.Enter welding process after the precompressed process, upper/lower electrode makes the fusing of nut boss 306 positions by high electric current 305, and is integrally welded with welding plate 303.Because in the welding process is high electric current, the caloric value of resistance own is bigger, and the projection welding upper/lower electrode need lead to the recirculated water cooling, prevents that the overheated projection welding upper/lower electrode that causes of upper/lower electrode is out of shape.Needing projection welder projection welding top electrode 301 and projection welding bottom electrode 304 are pressurizeed in this process is the maintenance stage, so that both are seamless after guaranteeing project-welding nut 302 and the 303 gold medal projection weldings of welding plate, has effectively guaranteed the welding quality of project-welding nut 302.Next process that enters projection welding then is a rest stage, rises projection welding top electrode 301, and employee's product that projection welding is intact takes off the process of promptly having finished the nut projection welding from projection welder.
If when project-welding nut switches to the projection welding double-screw bolt, only project-welding nut fixed mechanism 201 need be taken off from projection welding bottom electrode 304 and get final product, welding process is identical; During the projection welding double-screw bolt, nut fixed mechanism 201 residing positions in the projection welding bottom electrode 304 can be put in the screw thread position of double-screw bolt.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obvious realization of the present utility model is not subjected to the restriction of aforesaid way; as long as the various improvement of having adopted method design of the present utility model and technical scheme to carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all in protection domain of the present utility model.
