[0028] The following further illustrates this solution through specific embodiments.

[0029] Embodiment 1: A positioning and transfer tooling for an automobile rear subframe in this embodiment includes a boosting arm 2, a jaw assembly 3 and a skeleton main body 4. The boosting arm 2 is fixedly arranged on the upper surface of the connecting seat 9 of the skeleton main body 4. In this example, the boosting arm adopts a cantilever crane type boosting arm, and other conventional types of boosting arms can also be adopted. Connecting parts such as flanges are arranged above and are connected to the hoisting device.

[0030] The skeleton main body 4 includes profiling nylon blocks 5, legs 6, cross beams 7, reinforcing ribs 8, connecting seats 9 and a main beam 10. Among them, the legs 6, cross beams 7, reinforcing ribs 8, connecting seats 9 and the main beam 10 are fixed by butt welding. The profiling nylon blocks 5 are symmetrically arranged on the legs 6 of the skeleton main body 4. The profiling nylon blocks 5 are matched with the outer shape of the middle cross beam 200 on the rear subframe 1 and play a role of contact fixation during transfer.
