The invention discloses a lifting machine tool operating table. The lifting machine tool operating table comprises an operation box, supporting plates are fixedly connected to the two sides of the bottom of an inner cavity of the operation box, air cylinders are arranged on the inner sides of the two supporting plates, and connecting plates are fixedly connected to the ends, far away from the supporting plates, of the air cylinders; and a connecting block is fixedly connected to the position, between the two supporting plates, of the bottom of the inner cavity of the operation box, a bearing plate is arranged at the inner cavity of the operation box, and a connecting rod is arranged at the top of the bearing plate. According to the lifting machine tool operating table, the operation box, the supporting plates, the air cylinders, the connecting plates, the connecting block, the bearing plate, the connecting rod, a sliding rail, a limiting block, a first sliding block, a movable rod, a sliding groove and a second sliding block are matched, the problem that an existing machine tool operating table does not have the lifting function is solved, the condition that the height of the machine tool operating table cannot be adjusted according to the height of a user, errors during machining are reduced, and use of a user is facilitated.
