The invention relates to an assembling machine table capable of tightening automobile hub bolts with variable diameters and at variable positions and belongs to the field of automobile hub assembling equipment. The machine table comprises a rack, a program control box, a lifting locking device and a variable-diameter variable-phase fastening device. A supporting plate is fixedly installed on the rack, and the lifting locking device is arranged on the part, below the front end of the supporting plate, of the rack. A hoisting top plate is fixedly installed at the top of the supporting plate, and the variable-diameter variable-phase fastening device is fixedly hoisted below the hoisting top plate through hoisting rods. The machine table is simple in structure and novel in design, and the problem that corresponding assembling tables have to be replaced when types of existing automobile hubs are changed, consequently, the equipment input of a production enterprise is large, and the development of the enterprise is influenced to a certain extent is solved. By means of the assembling machine table, the automation degree and the reliability of fastening bolts on an automatic assembling line are greatly improved, meanwhile, due to the fact that the machine table is unattended equipment, the labor cost of the enterprise is reduced, the working efficiency is improved, and meanwhile the product quality is improved.
