It is welded outer ring.After welding, rotating electric machine 53 drives welding platform 4 to rotate+90 °, and another end plate is downward.
Later, material-receiving device 8 rises, and clamping device unclamps end plate, and driving means 7 pushes end plate open.Specifically, splicing is oily
Cylinder 81 drives splicing frame 82 to rise between welding platform 4 and conveying cylinder along Y-direction.First Y-direction clamping cylinder 612 driving first
Clamping plate 611 along Y-direction decline, meanwhile, the second Y-direction clamping cylinder 623 drive the second clamping plate 621 along Y-direction decline, then, X to
Mobile cylinder 613 drives the first clamping plate 611 along X to the first end for leaving end plate, meanwhile, pusher cylinder pushes push plate 71, will
The second end of end plate pushes away the second clamping plate 621, unloads end plate on splicing frame 82.
Splicing frame 82 declines after catching end plate, is placed on end plate on conveying cylinder and transports.Welding platform 4 rotates 180 ° and returns
To initial position, the first Y-direction clamping cylinder 612 drives the first clamping plate 611 to drop in recessed portion 42 along Y-direction, push cylinder
72 driving push plates 71 are along X to returning to initial position.
In other embodiments, which can otherwise be transferred to end plate in welding platform 4, example
It is such as drawn and is placed into welding platform 4 again by the way of vacuum or magnetic suction disc.The clamping device, which also can be set, to be welded
4 middle part of platform, using clamping inner circle rather than by the way of outer circle, or uses other common clamping structures of this field.The rotation of end plate
Gyration and rotation mode can also be different, and end plate is not limited to be welded 90 ° of upright positions, as long as can be realized welding gun
33 smoothly touch the Internal and external cycle of end plate notch and are welded, and the welding sequence of inner ring and outer ring also can change.It should
Second clamping device 62 can also be using the structure of similar first clamping device 61, using similar to mobile device with the first X
Device drives the second clamping plate 621 to clamp or unload bottom plate to movement by X, to substitute driving means 7, as long as being able to achieve
The handling of end plate.The push plate 71 and push cylinder 72 can also use other structures and move mode, as long as can be by end plate
It pushes away.The material-receiving device 8 can also catch end plate by the way of manipulator crawl, and be placed into conveying device 9.It should
Material-receiving device 8 and conveying device 9 also can be omitted.Driving device involved in the utility model can using cylinder, oil cylinder or
The driving device commonly used in the art such as motor, be not limited to the present embodiment in concrete scheme.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, or to above-mentioned technical proposal
It is freely combined, these are all within the protection scope of the present invention.
