PFSA240 EXC3BSE073476R1 Axial Positioning Accuracy

Loading and positioning of PFSA240 EXC3BSE073476R1: Since the overall shape of the tube is not determined, it is assumed that there is already a loading mechanism or manual loading. After loading, copper and aluminum tubes to determine a total of 5 degrees of freedom, that is, in addition to axial rotation outside the 5 degrees of freedom. Practice has proved that the five degrees of freedom, axial positioning accuracy on the welding quality of less impact, while the radial direction, rotation around the coordinate axis of the positioning accuracy of the welding quality of a greater impact;

PFSA240 EXC3BSE073476R1 must be clamped after positioning to ensure that the copper and aluminum tubes are completely under the control of the control system during the welding process. Due to the overall shape of the pipe is not determined, and to ensure the quality of welding, clamping near the end face of the copper and aluminum pipe. After clamping, the copper tube, aluminum tube axial still exists a certain distance, in the welding process requires relative displacement. The use of copper tube to aluminum tube insertion to complete the propulsion action;
