Supplementary processing tool

The utility model discloses a supplementary processing tool sets up on machine tool's working face, including fixing the support on the working face, the support upper end is equipped with the rotation axis, fixed cover is equipped with the workpiece setting platform on the rotation axis, and the work piece is fixed in the workpiece setting bench, rotation axis one end is connected with the rotating assembly who sets firmly on the support, the rotating assembly drive rotation axis and workpiece setting platform are rotatory. The utility model discloses a set up supplementary processing tool, carry out multidimensional processing after can a centre gripping, reduced the installation clamping face that the work piece adds the man hours requirement, and need not many times clamping, danger when having reduced staff holding workpiece to a certain extent. Carry out the rotation of workpiece setting platform through rotating assembly, can once only process a plurality of faces of work piece, reduced holding workpiece's number of times, improved machining efficiency effectively.
