Abstract
The utility model discloses a traceless spot-welding electrode which comprises a fixed electrode arranged on a support and an active electrode interacting with the fixed electrode. The fixed electrode is a CuCrZr plate arranged on the support through an elastic connecting piece. According to the traceless spot-welding electrode, no spots remain on the side where a part to be welded contacts with the fixed electrode through improvements of the fixed electrode, and the poor contact problem between the fixed electrode and the part to be welded in the prior art is avoided.
Description
Technical field
The utility model relates to spot welding device, relates in particular to a kind of electrode that can be used for automobile component is carried out the spot welding connection.
Background technology
Some automobile components such as car door etc. are double-decker, i.e. inner layer metal plate and outer metal plates; Both generally connect through electric welding at the edge, and welding set has two electrodes in the prior art, when operating parts to be welded is fixed on the clamp mechanism; And in two electrodes, one is fixed on this clamp mechanism as fixed electrode, and another one is a float electrode; In a plurality of welding positions, can be corresponding a plurality of fixed electrodes are set, and float electrode can move to assigned address as required; Interact with fixed electrode, the edge welding of inner layer metal plate and outer metal plates is fixing.
Chromium zirconium copper (CuCrZr) is common electrode material, has higher intensity and hardness, electric conductivity and thermal conductivity, and wearability and anti-attrition property are good, and hardness, intensity, electric conductivity and thermal conductivity are significantly increased after Ageing Treatment, are easy to welding.Be widely used in the motor commutator, mash welder, seam welder, butt welding machine is used electrode, and other high temperature requirement intensity, hardness, electric conductivity, the part of leading pad property.
Because the electrode tip area is less, can stay the calcination vestige after the welding when carrying out spot welding in the prior art, vestige can influence attractive in appearance and uniformity outer surface on the outer metal plates and be in.After the long-term use of welding set, deviation can take place in the fixed electrode position, might cause fixed electrode and parts loose contact to be welded, influences welding effect.
The utility model content
The utility model provides a kind of electrode, has solved the problem of fixed electrode and parts loose contact to be welded, and the side that parts to be welded are contacted with fixed electrode does not stay the trace point.
A kind of seamless spot-wedling electrode, comprise rack-mount fixed electrode and with the interactional float electrode of this fixed electrode, described fixed electrode is for to be installed in the chromium zirconium copper on the described support through Flexible Connector.
Described chromium zirconium copper is tabular, has increased the contact-making surface with welding assembly, therefore can not stay the calcination vestige after the welding.And float electrode still adopts existing structure, although still can leave a trace in float electrode one side, owing to be in the inboard of member, does not therefore influence outward appearance.
Described Flexible Connector is rubber-like metallic plate or Metallic rod, and when float electrode Contact welding relay part, Flexible Connector can drive the opposite side that chromium zirconium copper is close to welding assembly.
In order to clamp welding assembly, described support is provided with clamp mechanism.
The seamless spot-wedling electrode of the utility model can realize that through the improvement to fixed electrode the side that parts to be welded contact with fixed electrode does not stay the trace point, also avoided the loose contact problem of fixed electrode and parts to be welded in the prior art.
Description of drawings
Fig. 1 is the structural representation of the seamless spot-wedling electrode of the utility model;
Fig. 2 is the perspective view of the seamless spot-wedling electrode among Fig. 1.
The specific embodiment
Referring to accompanying drawing, a kind of seamless spot-wedling electrode of the utility model, comprise the fixed electrode that is installed on the support 1 and with the interactional float electrode of this fixed electrode (omitting float electrode among the figure).
In order to clamp welding assembly; Support 1 is provided with clamp mechanism; Clamp mechanism generally comprises the driving cylinder 2 that is fixed on the support 1, is fixedly mounted on first jaw 6 on the support 1, the clamp arm 4 that is connected with support 1 through connector 3; Clamp arm 4 one ends are provided with second jaw 5 that matches with first jaw 6, and the other end is connected with the piston rod that drives cylinder 2.
When driving the piston rod movement of cylinder 2, drive clamp arm 4 upsets, second jaw 5 is opened with respect to first jaw 6 or clamps, realize fixing welding assembly.
Fixed electrode is for to be installed in the chromium zirconium copper 7 on the support 1 through Flexible Connector 8.Flexible Connector 8 is flexible metallic plate, and its bottom is fixed on support 1 through base 9.Chromium zirconium copper 7 is fixed on the top of Flexible Connector 8 through screw.
Claims (2)
1. seamless spot-wedling electrode, comprise rack-mount fixed electrode and with the interactional float electrode of this fixed electrode, it is characterized in that described fixed electrode is for to be installed in the chromium zirconium copper on the described support through Flexible Connector.
2. seamless spot-wedling electrode as claimed in claim 1 is characterized in that, described Flexible Connector is rubber-like metallic plate or Metallic rod.
