The utility model relates to a hoisting device for an upper wheel rim of a homogeneity test machine, which adopts the hoisting control structure integrating the hydraulic way and the pneumatic way; the rapid hoisting operation of the upper wheel rim can be driven by a hydraulic mechanism, and during the process for adjusting the width of the cross section, a pneumatic mechanism can be adopted to control the mutual locking between an upper conical sleeve and a lower conical sleeve, thereby resolving the contradiction between the rapid hoisting and the locking during the width adjustment process, so that not only the integral test period is reduced, but also the positioning and the main shaft loading correctness are improved. The hoisting device comprises an oil cylinder, an air cylinder device and positioning conical sleeves, wherein, the oil cylinder is fixed on a stander of the homogeneity test machine, and a piston rod of the oil cylinder is tightly connected with a shell of the air cylinder device, and the air cylinder device is installed on a bearing sleeve of the upper wheel rim, and a piston shaft of the air cylinder device is fixedly connected with the positioning conical sleeves.
