Abstract
The utility model discloses a floating spot-welding electrode which comprises an upper electrode (1) and a lower electrode (5). The floating spot-welding electrode is characterized in that the lower end of the upper electrode is provided with a spherical head (6), an electrode cap (3) is sheathed on the spherical head, and is contacted with the spherical head through a concave spherical surface matched with the spherical head, the upper electrode can swing relative to the electrode cap through a spherical surface, and the lower end surface of the electrode cap is a plane, and is contacted with a workpiece; and the opening part of the concave spherical surface of the electrode cap (3) is provided with a retainer ring (2) to space the spherical head. The floating spot-welding electrode disclosed by the utility model has the beneficial effects that the upper electrode can swing within the certain axial scope through the spherical floating connection of the upper electrode and the electrode cap, and the lower end surface of the electrode cap can be adhered to the workpiece in parallel so as to ensure the flat appearance of welding spots.
Description
Technical field
The utility model relates to the spot-wedling electrode parts in a kind of Pressure Welding.
Background technology
Spot welding is a kind of electric resistance welding, and it is two workpiece that overlap joint assembles to be pressed between two columnar electrodes apply thrust, the method that a large amount of internal resistance heat that produce when utilizing the workpiece energising are welded.Mash welder work the time needs electrode of clamping, and 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 from the teeth outwards after the workpiece welding, influence the surface quality of welding work pieces.
In order to solve the irregular problem of solder joint, be employed in the mode that the copper cushion block transition is used in the welding position usually at present.But each welding all need be arranged again and increased working strength of workers by copper cushion block during this mode of this employing, reduces production efficiency.If the outward appearance solder joint is many, required copper cushion block is just many, has also just increased manufacturing cost.The replacing of copper cushion block, reconditioning simultaneously is also inconvenient.
The utility model content
The purpose of the utility model provides a kind of unsteady spot-wedling electrode, makes the relative surface of the work of top electrode in axially certain hunting range, the solder joint flat appearance after still guaranteeing to weld.
The described a kind of unsteady spot-wedling electrode of the utility model comprises top electrode and bottom electrode, and it is characterized in that: described top electrode lower end is provided with bulb; Electrode cap is placed on the bulb, and through contacting with bulb with the suitable interior concave spherical surface of this bulb, but top electrode cooperates the comparative electrode cap to swing through sphere, and the lower surface of described electrode cap is the plane and contacts with workpiece; Peristome at the interior concave spherical surface of electrode cap is provided with back-up ring, carries out spacing to bulb.Top electrode comparative electrode cap axially between the full swing amplitude be 9 °.
The beneficial effect of the utility model is to be connected with the sphere of electrode cap through top electrode, and top electrode is being swung in certain axial range, and its electrode cap lower surface still can parallel applying workpiece, has guaranteed the smooth outward appearance of solder joint.The consumable accessory of a whole set of electrode has only electrode cap simultaneously, can reuse through reconditioning.And need not use copper cushion block, welding procedure is the same with common spot welding, and the soldering turret passage is not had specific (special) requirements, has reduced working strength of workers.

Fig. 2 is the sketch map of this unsteady spot-wedling electrode when the full swing angle;
Fig. 3 is the described upper electrode arrangement sketch map of the utility model;
Fig. 4 is the described gasket construction sketch map of the utility model;
Fig. 5 is the described electrode cap structural representation of the utility model.
The specific embodiment
Engaging accompanying drawing below does further to set forth in detail to the utility model:
A kind of unsteady spot-wedling electrode as shown in Figure 1 comprises top electrode 1 and bottom electrode 5, and it is characterized in that: described top electrode lower end is provided with bulb 6; Electrode cap 3 is placed on the bulb, and through contacting with bulb with the suitable interior concave spherical surface of this bulb, and the lower surface of described electrode cap is the plane and contacts with workpiece; Peristome at the interior concave spherical surface of electrode cap 3 is provided with back-up ring 2, carries out spacing to bulb.But top electrode cooperates the comparative electrode cap to swing through sphere, and the full swing amplitude was 9 ° between it was axial.
This preferred embodiment adopts nobelium zirconium copper product to be processed into upper and lower electrode and electrode cap and back-up ring, and bottom electrode adopts existing tapered end face electrode.During welding,, implement welding then with upper and lower electrode alignment welded lap position.
As shown in Figure 2, when misoperation or other reason caused electrode soldering angle out of plumb, electrode cap can keep the plane contact with workpiece, can not cause outward appearance plane impression when guaranteeing spot welding, satisfies the presentation quality requirement.
Claims (2)
1. a unsteady spot-wedling electrode comprises top electrode (1) and bottom electrode (5), and it is characterized in that: described top electrode lower end is provided with bulb (6); Electrode cap (3) is placed on the bulb, and through contacting with bulb with the suitable interior concave spherical surface of this bulb, but top electrode cooperates the comparative electrode cap to swing through sphere, and the lower surface of described electrode cap is the plane and contacts with workpiece; Peristome at the interior concave spherical surface of electrode cap (3) is provided with back-up ring (2), carries out spacing to bulb.
2. unsteady spot-wedling electrode according to claim 1 is characterized in that: top electrode comparative electrode cap axially between the full swing amplitude be 9 °.
