Abstract

The invention discloses aluminum alloy wheel shape-correcting equipment which comprises rack, an output end of positioning air cylinder is arranged at the bottom of the rack corresponding to the center of the upper rotating disc and is vertically and upwards connected with positioning cone.

First claim

What is claimed is:

1. An aluminum alloy wheel shape-correcting equipment, comprising:
a rack;
a gear motor arranged on an upper part of the rack;
an upper rotating disc connected with an output end of the gear motor;
clamping devices arranged on the upper rotating disc;
a positioning air cylinder arranged at a bottom of the rack corresponding to a center of the upper rotating disc;
a positioning cone connected with an output end of the positioning air cylinder, wherein the positioning air cylinder drives the positioning cone to move upward and downward;
jacking air cylinders arranged at the bottom of the rack;
a lifting base fixedly connected with output ends of the jacking air cylinders, the jacking air cylinders drive the lifting base to move upward and downward; and
at least two conical rolling wheel devices arranged on the lifting base.

2. The aluminum alloy wheel shape-correcting equipment according to claim 1 , further comprising:
guiding columns fixed to the lifting base,
wherein each conical rolling wheel device includes a conical roller and a bearing assembly, and each conical roller is mounted at a top end of the corresponding guiding column through the corresponding bearing assembly.

3. The aluminum alloy wheel shape-correcting equipment according to claim 2 , further comprising:
a guiding plate arranged on the rack, lower parts of the guiding columns penetrate through the guiding plate.

4. The aluminum alloy wheel shape-correcting equipment according to claim 3 , wherein the guiding columns includes three guiding columns evenly arranged on the lifting base, and the corresponding conical rolling wheel device is mounted at a top end of each guiding column.

5. The aluminum alloy wheel shape-correcting equipment according to claim 1 , wherein the clamping devices includes at least two clamping devices evenly distributed on the upper rotating disc.

6. The aluminum alloy wheel shape-correcting equipment according to claim 5 , wherein each clamping device includes:
a compressing oil cylinder mounted on the upper rotating disc;
a hydraulic rotating joint mounted on the rack;
an oil pipe connecting the corresponding hydraulic rotating joint with the corresponding compressing oil cylinder; and
a compressing claw mounted at an output end of each compressing oil cylinder.
