In order to achieve the above object, the technical solution of the present invention is: the utility model provides a special fixture of special-shaped part grinding usefulness which characterized in that: including the wandering star wheel, the guide bar, clamp bolt, add the pressure disk and remove the pressure disk, the wandering star wheel surface is provided with the through-hole A that is used for holding special-shaped parts, the guide bar sets up in the wandering star wheel surface, the guide bar surface ring is equipped with the guide bar spring, it sets up directly over the wandering star wheel to remove the pressure disk, it is provided with the through-hole B that passes through with through-hole A corresponding step hole and make the guide bar on the removal pressure disk, clamp bolt's tieing sets up in the macropore in step hole, clamp bolt's double-screw bolt passes the aperture in step hole and extends to wandering star wheel one side, the double-screw bolt surface ring that extends to remove the pressure disk is equipped with the spring, the pressure disk sets.
Further, the wandering star wheel and the guide rod are integrally formed.
Further, the through hole A is a stepped hole.
Furthermore, the outer surface of the wandering star wheel is provided with gear teeth matched with a gear on the grinding machine tool.
Furthermore, the guide rods are arranged on the surface of the planetary gear in an annular array.
The utility model discloses rational in infrastructure, convenient to use through carrying out technical improvement to current grinding device, on the basis that does not change current grinding device structure, designs and has increased the special clamping anchor clamps to special-shaped part to enlarge the range of processing of this type of equipment, practiced thrift use cost, improved work efficiency.
