Description
Technical field
The present invention relates to a kind of mash welder electrode, more particularly, relate to a kind of universal electrode that can not produce load mould.
Background technology
Spot welding is a kind of electric resistance welding, and it is the workpiece that overlap joint is assembled, and is pressed between the two column copper electrodes and applies thrust, the method that a large amount of internal electrical thermal resistances that produce when utilizing the workpiece energising are welded.Need electrode of clamping during mash welder work, this electrode is a float electrode, after it moves axially with Work-sheet pressing, general float electrode is shaft-like single piece at present, taper seat is arranged at the top of its electrode stem, and taper seat is used for the mash welder clamping, is sphere or taper in the lower end of electrode stem, but the electrode tip of sphere or taper can stay pit on surface of the work, influence the surface quality of welding work pieces.
At this kind defective, a kind of combined electrode has also appearred on the market, it is combined by electrode stem and electrode cap, lower end at electrode stem is provided with bulb, electrode cap is by being connected with electrode stem with the suitable interior concave spherical surface of this bulb, for overcoming electrode tip stays pit at surface of the work defective, the electrode end surface of electrode cap is the plane, when electrode end surface and surface of the work are not parallel, electrode cap can be done freely to rotate with respect to electrode stem by sphere, thereby adjusts, makes electrode end surface, applying parallel with surface of the work automatically.But this kind electrode can only be used on the fixing point welding machine, has only the vertical installation of its electrode tip down, and it is coaxial that electrode cap and electrode tip could keep under the gravity effect, just can avoid producing on surface of the work impression.If but workpiece is fixed, when using hanging spot-welder to carry out mobile spot welding, its electrode often is in heeling condition or level, this combined electrode only otherwise be in plumbness, its electrode cap will be under the effect of gravity, front end is crooked down, and (the electrode cap front end is a solid, the front end quality is bigger), make electrode end surface and surface of the work not parallel, when pressing to workpiece, it can not fit fully with workpiece, can on surface of the work, stay horseshoe-shaped impression, influence the presentation quality of workpiece.
Summary of the invention
Technical problem to be solved by this invention is: a kind of universal electrode is provided, no matter which kind of location status its axis is in, its electrode end surface can not stay impression on surface of the work, guarantees the presentation quality of workpiece.
Technical scheme of the present invention is as follows: a kind of universal electrode, comprise electrode stem and electrode cap, end at electrode stem is provided with bulb, electrode cap is by being connected with electrode stem with the suitable interior concave spherical surface of this bulb, the both ends of the surface of electrode cap are the plane, and its key is that the both ends of the surface of described electrode cap are the plane perpendicular to axis, on described electrode stem, back-up ring is installed, on the electrode stem between this back-up ring and the described electrode cap, is pressed with spring.
The present invention also is a combined electrode, and electrode cap is connected by bulb with electrode stem, and when electrode end surface and surface of the work were not parallel, electrode cap can cooperate by sphere, does freely to rotate with respect to electrode stem; On electrode stem, install the spring of pressurized additional, spring force acts on the perpendicular end surface of electrode cap, electrode cap is supported by axial force all the time, this axial force is enough to overcome the gravity effect of electrode cap, even make the electrode cap axis not be in vertical state, also coaxial with electrode stem, thus make perpendicular to the electrode end surface of electrode cap axis parallelly with surface of the work, just can when applying thrust, not stay shape of a hoof impression at surface of the work yet.
For adjusting electrode cap like a cork, lining also is housed between the end face of described spring and electrode cap, the endoporus of this lining is a shoulder hole, its small diameter bore near spring and with the electrode stem matched in clearance, and the close described electrode cap of large diameter hole, the end face of large diameter hole and the end face of electrode cap offset.By the effect of lining, spring force acts on the position, outer ring of electrode cap end face, makes electrode cap just can keep coaxial with electrode stem under the effect of less spring force.
As to further improvement in the technical proposal, in order to bear spring force reliably, described back-up ring and described electrode stem matched in clearance, this back-up ring offsets with the snap ring that is stuck on the electrode stem under the effect of described spring.
Further, described snap ring is that cross section is circular spring collar, is provided with annular groove in the aperture of described back-up ring outboard end, and the inner ring surface of this annular groove is pressed on the periphery of described snap ring, thereby snap ring can not taken off from bullet on the electrode stem.
Be the cooling electrode bar, have the cooling hole in the inside of described electrode stem, this cooling hole is a blind hole, is positioned at described bulb at the bottom of its hole, and then open at the end away from bulb in the aperture.
The invention has the beneficial effects as follows: the present invention can be used in hanging spot-welder, no matter which kind of location status the electrode axis is in, its electrode end surface is parallel with surface of the work all the time, can fit with surface of the work after compressing, and can not stay pit or shape of a hoof impression on surface of the work.
