PFSK141 3BSE006513R1 copper and aluminum pipe butt welding machine fixture including positioning, clamping and clamping specific three parts. Because the fixture is in direct contact with the workpiece, so the accuracy of the fixture directly affects the quality of welding, must be treated carefully. In this paper, we only consider the linear pipe, welding process must limit the copper pipe, aluminum pipe 5 degrees of freedom, as shown in Figure 5, in addition to the Y-axis rotation around the degree of freedom outside the 5 degrees of freedom. If you consider the overall shape of the pipe after welding, you have to limit the 6 degrees of freedom, you must design the corresponding special fixture to achieve complete positioning.

PFSK141 3BSE006513R1 According to the characteristics of the copper and aluminum tube, and welding needs, the fixture is designed for the upper and lower parting of the mold long hole shape, as shown in Figure 5, so that 4 degrees of freedom can be limited, that is, the fixture itself can achieve 4 degrees of freedom of positioning. In the copper and aluminum tube end face set a certain positioning piece, so that the copper and aluminum tube end face contact positioning piece, you can limit the fifth degree of freedom. Practice has proved that the axial positioning accuracy of the copper and aluminum tube on the welding quality impact is small, compared with the other four positioning accuracy on the welding quality impact. Design focus should be placed on the upper and lower mold clamp specific, its processing accuracy directly affects the welding quality.
