Abstract
The utility model relates to a resistance spot welding electrode frock of filter screen subassembly fixes on spot welding equipment through last electrode arm and bottom arm, divide into two upper and lower electrodes, and the tip of two electrodes is provided with the pitch arc curved surface of indent, and the camber that goes up the pitch arc curved surface of electrode is less than the camber of filter screen subassembly, and the camber of the pitch arc curved surface of bottom electrode is less than the camber of the pitch arc curved surface of electrode. The utility model discloses having replaced manual operation, having realized the good laminating of face of weld, had simple structure, convenient operation greatly improves production efficiency's advantage.
Description
Technical field
The utility model relates to a kind of spot-wedling electrode frock, especially a kind of lifetime of resistance spot welding electrode frock of net-filter assembly.
Background technology
Certain net-filter assembly is cylindric, filter screen is coated in the middle of two joints, and adopt percussion spot welding method to be formed by connecting, in production in the past, percussion spot welding electrode used is " pen type " structure held, and the spot welding contact surface diameter of electrode tip is generally only φ about 1mm.Operator holds two electrodes filter screen joint place spot welding one week.For reaching instructions for use, therefore require that welding is rear generally needs spot welding 15-20 time without the defect such as sealing-off and non-seam, circumferential weld could be closed, and operation is compared wastes time and energy.And because the contact surface of tradition " pen type " electrode is less, therefore spot size is little.If spot pitch is comparatively large, be easy to occur non-seam defect; If spot pitch is too small, repetition spot welding phenomenon can be there is, cause the problems such as production efficiency obviously reduces.
Summary of the invention
For above deficiency, the purpose of this utility model is to carry out following improvement to traditional " pen type " percussion spot welding electrode, realize the good connection of the one week weld seam in joint, and filter screen is without sealing-off and incomplete fusion defect, spot welding production efficiency is greatly improved.
The technical solution of the utility model is, the lifetime of resistance spot welding electrode frock of net-filter assembly is fixed on spot-welding equipment by upper electrode arm and bottom arm, be divided into upper and lower two electrodes, the end of two electrodes is provided with the camber line curved surface of indent, the curvature of the camber line curved surface of top electrode is less than the curvature of net-filter assembly, the curvature of the camber line curved surface of bottom electrode is less than the curvature of the camber line curved surface of top electrode, and described electrode material is chromium-copper or chrome zirconium copper alloy.
In percussion spot welding production process, net-filter assembly is placed on the camber line place of bottom electrode, is realized the welding of filter screen and joint by the energising of upper/lower electrode, pressurization.Wherein bottom electrode takes into account support and welding effect, and top electrode produces plastic deformation due to spot welding course of exerting pressure, overlaps with the profile profile generating portion of part, plays the effect of welding, forms the weld seam of certain length; After spot welding once, rotate this net-filter assembly, repeat above-mentioned steps 2-3 time, the percussion spot welding that can realize girth seam connects.
It is simple that the utility model has structure, easy to operate, the advantage such as greatly to enhance productivity.Upper and lower electrode is fixed on percussion spot welding equipment, instead of manual operations.Upper and lower electrode is with arc-shaped structure, and camber line curvature is all little than External Shape curvature, can realize the good fit of solder side, contributes to enhancing productivity.For ensureing the service life of electrode, this spot-wedling electrode material is that chromium-copper or chrome zirconium copper alloy common used material are made, and wearability is better, high life.By the improvement to electrode, greatly enhance productivity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is service condition schematic diagram of the present utility model.
Detailed description of the invention
As shown in the figure, the lifetime of resistance spot welding electrode frock of net-filter assembly is fixed on spot-welding equipment 5 by upper electrode arm 3 and bottom arm 4, be divided into upper and lower two electrodes, the end of two electrodes is provided with the camber line curved surface of indent, the curvature of the camber line curved surface of top electrode 1 is less than the curvature of net-filter assembly 6, the curvature of the camber line curved surface of bottom electrode 2 is less than the curvature of the camber line curved surface of top electrode 1, and described electrode material is chromium-copper or chrome zirconium copper alloy.
During use, the hand-held net-filter assembly of operator, is placed on bottom electrode 2 place.By pedal gauge tap, control top electrode 1 and close, complete a spot welding, namely filter screen 7 is welded in filter screen joint 8.After top electrode 1 lifts, rotary sieve assembly 6, repeats above-mentioned action 2-3 time, can complete the connection of a net-filter assembly one week weld seam.
Claims (2)
