Workpiece numerical control milling turn-over device with pushrods having square grooves

The utility model relates to a workpiece numerical control milling turn-over device with pushrods having square grooves, which is characterized in that a right-angle reference surface is arranged on a work table provided with two guide grooves perpendicular to each other, two pushrods can be inserted into slots arranged below the two guide grooves which are perpendicular to each other, and are provided with a plurality of square grooves, one end of each of the two pushrods is connected with a cylinder via a joint, and pressing blocks matching with the square grooves are movably arranged on the two guide grooves. The workpiece numerical control milling turn-over device has the advantages that by the aid of the turn-over device, processes of machining four right-angle positioning blocks and fixation with glue can be omitted when in numerical control milling turn-over operation, the work table top can not be damaged, material can be saved, time can be shortened, and working efficiency and product quality can be
