Type selecting to be selected according to the actual situation, guarantee spot welding after the completion of, pseudo electrode can return to initial position.
Adaptive pseudo electrode mechanism using the utility model for tube sheet spot welding is as follows come the process for carrying out pipe fitting welding:
The underface that lower electrode moves to pseudo electrode is moved then up, in moving process, the pushing and pressing face contact of lower electrode and pseudo electrode, and
Push up pseudo electrode.Pseudo electrode under the promotion of lower electrode, drive pseudo electrode mounting base move upwardly together, guide rail also with
Upward sliding, and spring is stretched.After pseudo electrode is contacted with pipe fitting, pseudo electrode mounting base and guide rod stop movement, lower electrode
Upward pressure is applied to pseudo electrode, and since pseudo electrode tiltable is adjusted, by lower electrode to its pressure effect and pipe fitting
Limit of the lower surface to it, pseudo electrode wing drop are adjusted so that its contact surface fits with pipe fitting lower surface, at this point, pseudo electrode
The area of contact and fitting with pipe fitting is maximum, and lower electrode is thus conducted to the electric current of pipe fitting and pressure is dispersed,
It prevents pressure from crossing havoc pipe fitting, also makes the weld indentation of pipe fitting minimum, ensure that pipe fitting quality of welding spot.Then, upper/lower electrode
It is powered and generates resistance heat, form solder joint at this, complete the welding at this.After the completion of welding, lower electrode leaves and moves to next
A bond pad locations, pseudo electrode lose lower electrode to its support force, under the action of spring-return power, guide rod slide downward, and band
Dynamic pseudo electrode mounting base and pseudo electrode move down, and are returned to initial position.
Combine figure embodiment that the utility model is described in detail above, those skilled in the art can root
Many variations example is made to the utility model according to above description.Thus, certain details in embodiment should not constitute practical to this
Novel restriction, the utility model will be using the ranges that the appended claims define as the protection scope of the utility model.
