There is the cotter pilotage component for preventing the extension box axial-rotation to be processed；Being used in the outside of locating piece at least two will
The extension box to be processed is pressed on the pressure head on locating piece；The axial connecting line of the locating shaft and the cotter pilotage component is right with this
The angle of linea angulata is θ.
Further, the value range of θ is 0 ° to 12 °.
Further, there are four stations for tool on the bottom plate.
Further, the cotter pilotage component includes the location key seat being positioned on the bottom plate, which has logical
Hole is provided with cotter pilotage in the through-hole, and described cotter pilotage one end is stretched out outside the through-hole, and the through-hole other end is provided with plug.
Further, hydraulic corner cylinder is additionally provided on the bottom plate；Hydraulic corner cylinder piston rod upper end cantilever is set
Pressing plate is set, the free end of the pressing plate connects the pressure head upper end.
Further, the side of the bottom plate is equipped with the hand rotary valve opened or closed for controlling the hydraulic corner cylinder,
And the hand rotary valve is positioned on the bottom plate by fixed block.
The beneficial effects of the utility model include: that structure is simple, registration, and are restructured by existing fixture, contracting
The short fixture R&D cycle reduces fixture research and development cost, greatly improves the production capacity of extension box processing.
