The utility model can be welded with workpiece of ordinary structure or of complex section; convex (welding) points can be distributed along a circumference or along a straight line. Due to the floating function of a joint 5, the electrode can realize automatic location during plural-convex-(welding)-point welding, even stress on the convex (welding) points and even flowed head deformation, thereby high joint quality of workpiece is obtained; meanwhile, the electrode adopts double seal ring combined structure, thereby possessing good heat dispersion effect and long service life of the electrode head.
Description
The utility model is one group of automatic locating insert electrode with floating junction, is the electrode special of protruding (point) welding machine, is used to weld the workpiece with a plurality of salient points and the workpiece of 2～3 solder joints of a spot welding.
When multi-convex point welded, because the height of each salient point is variant, the depth of parallelism of upper/lower electrode had error, so the stressed and conquassation deflection of each salient point all is different.After the energising, the little salient point of conquassation distortion often can not form normal nugget, adds the displacement phenomenon of salient point, and joint quality does not often reach designing requirement.In order to address the above problem, the way that adopts is at present: additional preheating pulse and rotary type electrode tip.
The rotary type electrode tip has solved the unbalanced problem of pressure between salient point preferably, and still, the heat radiation of electrode is not solved at all.In existing electrode, not that to decrease because of the very fast jumping-up of the bad electrode tip that dispels the heat is sticking be exactly that cooling fluid leaks and pollutes workpiece and environment.
The purpose of this utility model provides a kind of automatic locating insert electrode, and this electrode radiating rate is fast, and cooling fluid does not leak, and salient point conquassation amount is even, and the joint quality of workpiece is good.
This automatic locating insert electrode, comprise a body sub-assembly, the one group of transition joint that can change according to the different operating environment and be installed in the electrode tip that under different occasions, uses in the transition joint and form, it is characterized in that: said body sub-assembly, comprise floating junction 5, body 1, retaining ring 3 and sealing ring 2,4, the inner surface top of floating junction 5 is the garden conical surface, the bottom is followed successively by the spill sphere and the face of cylinder, and outer surface is the face of cylinder and is processed with seal groove in its underpart and following seam; The top of body 1 is the sphere and the face of cylinder, and the bottom is a taper seat, and the middle part is processed with screw thread and seal groove, and endoporus is a through hole; Retaining ring 3 inner surface tops are last seam, and the bottom is following seam, and the middle part is a screwed hole, and retaining ring 3 is pressed on floating junction 5 on the body 1 by seam, screw thread up and down, and floating junction 5 can be swung arbitrarily at body 1 upper edge sphere; Said double cone joint 7 outer surface top and the bottom are taper seat, and the middle part is that cuboid has on it and is used to dismantle the screwed hole that electrode tip is used, and the endoporus of joint is a through hole; Said C type joint 10, the bottom is a taper seat, the screwed hole of one road cooling water hole and two fixed electrode heads is arranged at top; Said rectangle joint 13 is the square top and round bottom structure, and two conical bores of top cuboid bilateral symmetry distribution, lower cone body, endoporus are the right-angled intersection distribution so that the through electrode tip bottom of cooling fluid; The top of said cylindricality joint 15 is cylinder, and its upper edge circumference is 3 conical bores of distribution evenly, through electrode tip triangular in shape bottom, interior cooling hole; Said flat tip electrode 6 top are cylinders, and the bottom is a cone, and the cooling hole is a blind hole, and said rectangular electrode head 9 is cuboids that have the taper locating surface, and respectively there is a fabrication hole locating surface both sides; Said strip electrode head is a cuboid that has locating surface, and respectively there is a thread connection hole locating surface both sides.
Body 1, sealing ring 2,4, retaining ring 3 and floating junction 5 formed a body sub-assembly, the electrode tip of different structure and the corresponding transition joint body sub-assembly of packing into, just forms the automatic locating insert electrode of six kinds of different purposes.
