Double-Point Optical Fiber Detection System of Two-Welding Torch Counterguard Automation Welding Machine

Two-Welding torch counterguard automation welding machine adopts double-optical fiber transmission sensor to detect the vertical tube generatrix double-point of radiator in z-axis direction in order to ensure the precise position of the starting welding point during detecting the workpiece. After controller real-timely collects the keying signal of double-optical fiber sensor through the trigger signal input port of 6k four-axis moving controller, the welding length is confirmed through signal priority judgment and the real-time geometric model processing. Last controller emits the signal to control the starting weld position. The test result shows that the precision of staring weld position can reach ±0.01mm. Its can satisfy with the precise request of welding machine.
