It is using the advantageous effect of above technical scheme：A kind of screw thread process work of nonstandard outer-hexagonal bolt of the present invention
Dress, the specifically used step of this tooling are：The height of support plate is adjusted according to the thickness of nonstandard outer-hexagonal bolt head to be processed
Degree keeps bolt head end face just close with gripping block upper surface, ensures that bolt shank is located at gripping block upper end, makes tool sharpening
When screw thread, gripping block will not cause to interfere, and when Bolt sizes are larger, rotation crank one drives threaded rod rotation, threaded rod to drive
Support plate declines, and when Bolt sizes are smaller, rotate backward crank one, support plate is made to increase, outer-hexagonal bolt is upside down in support
Plate upper end makes two angles to oppose of bolt head be aligned with gripping block inside opening, rotates crank two, and reverse-flighted screw is made to turn
Dynamic, reverse-flighted screw drives two slides to center snap, and the gripping block on slide is equipped with 120 ° of opening, different nonstandard outer-hexagonals
The head of bolt is regular hexagon, and clamping is fixed in bolt head by two gripping blocks, is then carried out to bar portion by cutter
The characteristics of screw thread process, this tooling utilizes bolt head regular hexagon, using the gripping block being open with 120 °, realizes to not
With the clamping of size outer-hexagonal bolt, the trouble for each nonstandard bolt manufacture fixture is avoided, tooling manufacturing cost is saved.
