Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 1, this copper bar rotor motor welding tooling, comprises a rotatable platform, and rotatable platform comprises cup dolly 1, rotating turret 2.
As shown in Figure 5, the center of this cup dolly 1 is provided with locating dowel 3.
As shown in Figure 6, rotating turret 2 comprises round table surface 4 and rounded bottom surface 5, and the some support bars 6 by edge between round table surface 4 with rounded bottom surface 5 are connected, and are provided with locating hole 7 at the center of rounded bottom surface.
As shown in Figure 1, be provided with angular contact bearing 8 in locating hole, the locating dowel 3 on cup dolly is through the locating hole 7 on rotating turret rounded bottom surface, and rotating turret 2 is free to rotate.
As shown in Figure 1, round table surface 4, rounded bottom surface 5 and support bar 6 enclose the cavity of formation as rotor axocoel 9, are provided with through hole at the center of round table surface 4, and rotor shaft extension can be inserted in rotor axocoel 9 through the through hole on round table surface 4.
As shown in Figure 1, round table surface 4 is provided with welding packing ring 10.The structure of welding packing ring 10 is shown in shown in accompanying drawing 2, and welding packing ring 10 is a rounded ring body, and be provided with some back-up blocks 11 at the surface uniform of rounded ring body, 3 is visible by reference to the accompanying drawings, between the bottom and rounded ring body of back-up block 11 lateral surface, be provided with insertion groove 12.
