[0027] The wheel blank is clamped into place by a mobile clamping structure, and the wheel blank is clamped for a second time by a fixed clamping claw 9. Compared with the prior art method of clamping once by a clamping structure only, the clamping stability is better. A driving structure is used to drive the mobile clamping structure to clamp the wheel blank. When clamping wheel blanks of different wheel types and sizes, there is no need to readjust the clamping point, thereby improving the clamping efficiency.
