The invention discloses a rotary table device suitable for feeding and material discharging. The device comprises a fixed rack and a lifting rack which is installed on one side surface of the fixed rack, wherein a rotary table is installed above the lifting rack through a slewing bearing driven to rotate, the rotary table comprises two positioning clamping fixtures which are symmetrically arranged, each of the positioning clamping fixtures is provided with at least two positioning holes, positioning pins which correspond to the positioning holes and can be driven to ascend and descend are arranged in the fixing rack, and after the positioning pins ascend, the positioning pins are inserted into the positioning holes to fix the rotary table and prevent the rotary table from rotating. According to the rotary table device, the influences of the positioning error and the rigidity degree of the rotary table on the machining precision are avoided, the machining precision can be improved, meanwhile, large cutting for
