摘要： PURPOSE:To execute satisfactory spot welding by constituting the title welding machine so that when one electrode abuts on an object to be welded, the other electrode follows up the one electrode direction, and always inserting and holding the object to be welded by prescribed pressing force. CONSTITUTION:By a movable arm 37, a pair of electrodes 2, 3 move to a position for inserting and holding an object to be welded. Subsequently, a cylinder 18 operates, a piston rod 18a elongates and one electrode 2 abuts on the object to be welded. Also, when the rod 18a advances, back pressure is generated, the cylinder head 18 moves to the upper part, and moves an electrode head 7 to the upper part through brackets 51, 52. The other electrode 3 moves from the lower part and by a pair of electrodes 2, 3, the object to be welded is inserted and held by prescribed pressing force. A pair of electrodes 2, 3 are guided along a weld line of the object to be welded by the robot arm 37, while executing an electric conduction, and execute desired roll spot welding. In such a way, even if a pair of electrodes are worn out and a pressure point of the electrode is deflected, the object to be welded is always inserted and held by prescribed pressing force and satisfactory welding can be executed.

摘要： PURPOSE:To execute satisfactory welding even if an electrode is worn out by connecting one electrode to a piston rod of a cylinder, and connecting the other electrode to the cylinder body, and also, connecting it to a sliding body which is fitted so as to be freely slidable to a guide member attached to a movable arm. CONSTITUTION:When a pair of electrodes 2, 3 move to a position where an object to be welded can be inserted and held, a cylinder 18 operates and elongates a piston rod 18a, the electrode 2 abuts on the object to be welded, and moves to the electrode 3. In this case, back pressure is generated and the electrode 3 connected to a pressure cylinder 18 moves to the upper part, and the object to be welded is inserted and held by a pair of electrodes 2, 3. This back pressure works until electrode pressing force of the electrode 2, 3 becomes equal. The electrodes 2, 3 are guided along a weld line of the object to be welded by a robot arm (movable arm) 37, while executing an electric conduction, and execute roll spot welding. In such a way, even if a pair of electrodes are worn out and an electrode pressure point is deflected, satisfactory roll spot welding can be executed without damaging the object to be welded.

摘要： PURPOSE:To automatically teach with a small number of teaching points at high accuracy a working orbit of a robot for optimizing a working state of a tool against a workpiece consisting of curves by providing a means for correcting the teaching points while a robot is actually run. CONSTITUTION:When there is a portion which is not suitable with respect to a matrix 50 shape on a working orbit interpolated from a teaching point, a stroke amount of a floating cylinder device 20 fluctuates at the portion to be out of a specific threshold value. The unsuitable portion out of the specific threshold value is stored in an NG section storing means 4 as NG sections per section corresponding to an interpolating point, and the interpolating point of the section is compensated by a correcting means 5 after completion of running of the working orbit. A second running is done by a new working orbit based on the compensated interpolating point, and thereafter running of a robot 10 and compensation of each teaching point are repeated until the stroke amounts in all sections are within the specific threshold value.

摘要： PURPOSE:To perform brazing of stable high quality by controlling the feed rate of a welding wire to form an optimum bead width corresponding to the gap quantity of an overlapping part of a couple of works. CONSTITUTION:The respective gap quantities at the position and inclination of the overlapping part 1c between a roof 1a and a quarter 1b of a body and points 1-N are measured by a sensor 4. These data along with the positional data of each paint are taken in a robot controller 8 where these data are analyzed. Based on a result of this analysis, a command is transmitted to a robot main body 9 and the robot position is controlled and then, a welding torch 5 is moved to the brazing starting point 1. Here, brazing conditions in accordance with the gap quantity data of the point 1 are selected and a condition command is sent to a welding machine main body 17. The welding machine main body by outputs conditions corresponding to the condition command of a current value and the wire feed rate and brazing is performed. The brazing conditions are changed over according to the gap data of the point 2 at the point 2 and this is repeated hereafter.

摘要： PURPOSE: To control the clearance between a forming roller and a forming punch as desired by detecting the bending angle of a plate immediately after bending and determining the deviation from allowable angle, and commanding the movement of an adjusting plate according to the deviation.
CONSTITUTION: A plate 24 is held between a forming punch 30 and a plate presser 34 to be bent. This formed product is sent to a guiding device 74 and held between a guide 78 and a clamper 80, and deviation is detected by deviation meters 86A, 86B of a measuring device 14. The detected value is sent to an arithmetic device 16 and bending angle is calculated. The bending angle is compared with preset range of allowable angle. If this value is above tolerance, a command is issued from a commanding device 18 to a driving cylinder 66 of an adjusting plate 64. By this command, the adjusting plate 64 moves to the direction to set the tolerance (amount of deviation) to zero, and desired clearance is obtained between the forming roller 42 and the forming punch 30.

摘要： PURPOSE:To prevent generation of the surface strain in embossing by forming the ordinary surface after a part to be embossed has formed with both an innerpunch and an embossing tool, which is protruded from a die excessively beforehand. CONSTITUTION:Prime material W is placed on a fixed female die 21 under a condition in which both an outer blank holder 24 and an inner punch 27 have ascended. The holder 24 is then so made to descend as to hold and clamp a circumferential part 26 of the material W between a protruding part 25 and a groove 26, as shown in the figure (a). At this time, the punch 27 is made to descend as a embossing tool 29 is made to protrude from forming surface of a female 21 by H the maximal dimension, then, an embossed part 2 is, as shown in the figure (b), formed onto the material W through both a recess part 30, which is provided onto the lower surface of the punch 27, and the tool 29. Then, as shown in fugure (c), the ordinary surface 1a is formed with both the lower surface of the punch 27 and the forming surface of the die 21. Thereafter, the holder 24 and the punch 27 are made to ascend together, then, thus formed product is taken out.
