Numerical control processing fixture for two perpendicularly-crossed shafts

The invention discloses a numerical control processing fixture for two perpendicularly-crossed shafts. A workpiece is positioned inside a fixed support; the excircle surface at one side of the fixed support is provided with a second shaft installation hole; and the centre line of the second shaft installation hole and the center line of the fixed support are perpendicular to each other. A compression screw is arranged on the end surface of the opening end of the fixed support; and the bottom of the fixed support is provided with an adjusting screw by which a compression block is in close fit with the excircle surface of a first shaft of the workpiece. A step surface at the upper end of an inner hole of the fixed support is a positioning flange of the workpiece. By use of the numerical control processing fixture, the clamping force of a machine tool claw does not directly act on the workpiece, so the deformation of the workpiece caused by clamping is effectively reduced, and meanwhile deformation resulting fro
