The invention relates to a part assembly table, in particular to a jacking rotary table. The jacking rotary table comprises a worktable, a rotating cylinder, a locking device, a rotating supporting seat, a locking cylinder, a jacking cylinder, a bracket and a box; the locking cylinder and the jacking cylinder are mounted on the bracket; the box is connected with a piston rod of the jacking cylinder; the rotating cylinder is mounted in the box; the worktable is positioned above the box, is driven to rotate by the rotating cylinder, and is driven to lift through the jacking cylinder along with the box; the rotating supporting seat is positioned below the box, and is driven to rotate by the locking cylinder; and the rotating supporting seat is provided with the locking device used for locking the box and the worktable for preventing the box and the worktable from falling. The jacking rotary table integrates jacking, rotation and locking, uses the cylinders as power elements, can overcome such defects as unstable jacking table, complex structure, large occupied space and difficult debugging, finishes all actions of the whole table, increases the reliability of the table, and improves the assembly efficiency on a vehicle engine production line.
