Described locating piece one side has the screwed hole connecting with locating hole, and tie down screw is loaded on screwed hole.
Described locating hole is comprised of V-arrangement section holes and hole, square-section, and drill bushing center line equates with the radius of part cylindrical portion to be processed to the distance of V-arrangement section holes inwall two planes.
Described bushing plate is loaded on locating piece through screw, straight pin.
Locating hole cross section forms with the two sections that is approximately square-section by being approximately V-arrangement cross section.V-arrangement face is close to the only hole of part boss periphery makes only hole boss be able to accurate location, and tie down screw clamps part by the screwed hole of opposite side.Drill bushing is loaded in bushing plate small stair hole, and bushing plate and locating piece are located by straight pin, guarantees boss center, the only hole of drill bushing center alignment element.Together with bushing plate is connected by screw with locating piece.Tie down screw is welded by screw rod and moving rod.Compare with other technologies, the utility model accurate positioning, simple in structure, easy to adjust, with low cost and easily maintenance are applicable very extensive.
