20090050607 | Spot Welding Tongs Including a Compensation Unit Equipped With a Curved Connector Element - The invention relates to spot welding tongs with tong compensation, including a tong base body ( | 02-26-2009 |
20090266797 | SPOT WELDING TONGS FOR ROBOTIC APPLICATIONS IN RESISTANCE WELDING OR WORKPIECES - There are spot welding tongs for robotic applications in resistance welding of workpieces, in particular sheets, comprising tong arms, mounted such as to pivot on a base body, which may be adjusted using an operator and to which electrode holders for the electrodes are fixed and a winding device with a pay-out roller and a wind-in roller, for the winding in and out of a strip to protect at least one electrode. According to one embodiment, such spot welding tongs may be produced, in which access is not seriously affected and with a very simple and compact construction, whereby the pay-out roller and the wind-in roller of the winding device are arranged on the base body, or the tongs arm and at least one guide groove, for guiding the strip, is arranged in the tongs arm and/or the electrode holder. | 10-29-2009 |
20110073571 | Spot welding gun for resistance welding of workpieces - A spot welding gun for resistance welding of workpieces, includes a base body and a bracket, in which electrode holders are arranged, the electrodes being in turn arranged in the holders. At least one electrode holder is fixed to an actuator that enables the electrode holder fixed thereto with the electrode to be displaced in longitudinal direction towards other electrodes. To protect the electrodes, a winding device with a band is arranged, the band being displaceably arranged between the contact surface of the electrode and the workpiece opposite the electrode. The winding device assigned to the displaceable electrode is connected to the displaceable electrode so that it moves at the same time as the electrode when the electrode is moved in longitudinal direction. The electrode holders and the electrodes have devices for guiding the band from the winding device axially along the electrode holders towards the electrode and vice versa. | 03-31-2011 |
