     DETAILED DESCRIPTION 
     It should be noted that embodiments of the present disclosure and features of the embodiments may be combined with one another without conflict. 
     The technical solution of the present disclosure will be described clearly and completely hereinafter with reference to the accompanying drawings and in combination with embodiments, and obviously, the embodiments described are only a part of embodiments of the present disclosure, and are not all of embodiments thereof. Based on the embodiments of the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without involving any inventive effort fall within the protection scope of the present disclosure. 
     The aluminum alloy wheel shape-correcting equipment of an embodiment of the present invention is described below in conjunction with an embodiment with reference to  FIG. 1-5 . 
     An aluminum alloy reel-correcting equipment comprises a rack  1 , a gear motor  2 , an upper rotating disc  6 , a lower rotating disc  5 , a compressing oil cylinder  8 , a compressing claw  10 , a bearing roller  13 , a bearing assembly  14 , a guiding column  16 , a lifting base  18 , a guiding plate  17 , a sealing air cylinder  22 , a positioning air cylinder  19 , a positioning joint  20 , a bearing block  11 , a carrier roller  12  and the like. The gear motor  2  is arranged at the top end of the rack  1  through a bolt, the upper rotating disk  6  is connected with the gear motor  2 , the gear motor  2  can drive the upper rotating disk  6  to rotate, the hydraulic rotating joint  5  is fixed on the rack  1  through a bolt and is connected with the upper rotating disk  6 , the compressing cylinder  8  is arranged on the upper rotating disk  6  through a screw  9 , the compressing cylinder  8  and the hydraulic rotating joint  5  are connected through a compressing pipe  7 , the compressing cylinder  10  is arranged on the compressing cylinder  8 , the control roller  13 , the bearing assembly  14  and the sizing cylinder  16  are assembled together, three sets of bolts are arranged on the sliding cylinder  18 , the guiding cylinder  16  penetrates through the sizing cylinder  16  and acts as a guide, the three sets of bolts are arranged at the bottom end of the sliding cylinder  1  and act as a guide, and the three sets of bolts are arranged on the sliding cylinder  18 , and can drive lifting base  18  to move from top to bottom, positioning air cylinder  19  is installed at the bottom end of rack  1 , positioning cone  20  is installed on a piston rod of positioning air cylinder  19 , bearing block  11  is fixed on rack  1 , carrier roller  12  is connected with bearing block  11 , and a plurality of carrier rollers  12  and bearing block  11  form a roller way conveying system. 
     In operation, the roller conveyor system of carrier roller  12  and bearing block  11  transports the aluminum alloy wheel  21  to the central working area of the plant ( FIG. 2 ). 
     The positioning air cylinder  19  then drives the positioning cone  20  to move upward, lifting the aluminum alloy wheel  21  up to the upper rotating disc  6 , and the compressing oil cylinder  8  drives the compressing claw  10  to rotate and the compress wheel  21  with the compressing claw  10  ( FIG. 4 ). 
     After the compressing claw  10  presses the wheel  21 , the positioning air cylinder  19  brings the positioning cone  20  down to the initial position ( FIG. 5 ). 
     Then, the gear motor  2  rotates the upper rotating disc  6  slowly. Since the hydraulic rotating joint  5  is mounted, the compressing claw  10  is still in a state of pressing the reel  21  at this time. Meanwhile, the three packing air cylinders  22  synchronously drive the lifting base  18  to move upwards and drive the three sets of the control roller  13 , the bearing assembly  14  and the sizing column  16  to move upwards until the control roller  14  contacts with the inner wall of the wheel  21  ( FIG. 5 ). 
     During the racking air cylinder  22  up run, the aluminum alloy wheel  21  is slowly rotating; meanwhile, since the bearing assembly  14  is provided in the semiconductor roller  13 , the semiconductor roller  13  also rotates. Therefore, the packing air cylinder  22  causes the three control rollers  13  to roll and press the cavity of the aluminum alloy wheel  21  outwards and deform the cavity, thereby performing the shape correction function. 
     Compared with the prior art, the aluminum alloy wheel shape-correcting equipment of the present invention has the following advantages: 
     The invention can meet the requirement of shape correction of aluminum alloy wheel, and has the characteristics of simple structure and convenient operation.
