SPOT-WELDING APPARATUS WITH AUTO SENCING FUNCTION OF WELDING WIDTH

摘要

The present invention relates to an electric spot welding devices, more specifically, cooling fan controller be configured to that vehicle is hit by a bullet that type (lead typewriting) component elements are formed among the terminal part of main body be soldered to electricity node, automatically detect and find out that the bad state of benefit and electric spot welding is related to the weld width of possible resistance spot welding equipment and detects automatically fastly in this way by one change in weld width. ;Latent structure of the invention is that tip is sitting on a upper surface of lead support framework,Bracket is set to the lead-type part that transport conveyor is formed in the internal terminal installation when Y-axis is mounted for transmitting the side of main body,A T shapes basang is located in the Y-axis to be directly seated on the X-axis linear flow for including the separating of robot(R)With X-axis and transfer base plate basang linear flows,Being set to transfer base plate is the first hydraulic cylinder with a first piston,So as to the flowing in upward/downward direction,It is fixed to first piston and is provided welding in the base,It is welded in and is equipped with flow plate outstanding/correct and left side/correct flow plate is to left side/with the pedestal of the identical flowing L/R of highest left sensor termination contact flowing and correctly flow to left side/just,The cylinder body provided in second hydraulic cylinder and floating plate,Left side/correct flowing provides at the bottom of plate and stream is taken to be applied to the welding point for being set to top for welding including tip portion and pedestal(W)Lead end device type component left/right electrical leads contact the dedicated main body from terminal outside identical flowing welding flow plate left/right shift amount left/right when flowing when,Its left side for being used to detect the sensor terminal and flow plate move quantity detected and generated by the displacement sensor that signal is received in receiving one control contact-detection sensor displacement flow amount,On the left of in this way/it is correctly the stream for being applied to weld tip ON/OFF,Decide whether the tolerance of this basis displacement width being previously entered it is characterized by comprising a controller.
