Abstract
The invention relates to a sot welding machine, which is improved on the basis of a conventional fixed platform, an upper electrode and a lower electrode. The sot welding machine comprises a table surface and a driving mechanism, wherein a work piece to be welded is placed on the table surface; the driving mechanism drives the table surface to lift and descend; the table surface is positioned between the fixed platform and the upper electrode; and a through hole opposite to the lower electrode is formed on the table surface. When the spot welding machine is used for spot welding, the descending of the table surface can be controlled by applying the upper electrode to the work piece to be welded; and when the work piece to be welded is contacted with the lower electrode for spot welding, the table surface stops descending as long as the upper electrode stops moving down. Therefore, by adopting the spot welding machine, compensation can be obtained automatically by the descending of thetable surface, so that production efficiency is improved greatly, the quality of spot welding is ensured, and a quality accident caused by human factors is avoided by a mode of adjusting the height of the lower electrode without a person; and the sot welding machine is characterized by simple structure, good generality and low modification cost.
