Summary of the invention
The purpose of present technique provides a kind of bigger circumscribed milling head of motor offset of adjusting range of lead angle.
The circumscribed milling head of this motor offset comprises support, and the right side of support is provided with rotor plate, and the right side of rotor plate is fixed with the milling cutter cover, and rotor plate and motor cabinet are fixed, and the cutter spindle and the milling cutter cover that are fixed with milling cutter form revolute pair; Motor output shaft links to each other with cutter spindle through being with synchronously; One is passed said right side with the perpendicular pivot in said right side and rotor plate is fixedly linked, and in support, is provided with to be used to drive pivotally supported drive unit; Drive unit can through pivot drive rotor plate on said right side around the axis rotary electric machine main shaft of pivot sidepiece at cutter spindle.
The beneficial effect of present technique: rotate around pivotal axis because present technique, drives rotor plate through the drive device drives pivoted, thereby change lead angle; And because electric machine main shaft is at the sidepiece of cutter spindle; Thereby, in the present technique adjusting range of lead angle can reach ± 80 °, adjusting range is very big.
The above-mentioned circumscribed milling head of motor offset, said drive unit comprise that rotation is arranged on the worm screw in the support, the worm gear that cooperates with worm screw, and worm-wheel shaft is said pivot.Drive pivoted through worm-and-wheel gear, make that the pivot positioning accuracy is higher, reached ± 30 " (seconds).
The above-mentioned circumscribed milling head of motor offset, the syndeton of rotor plate and right side is: on the right side, have the T-slot that the cross section is a T shape, T-slot is the arc of center line for the axis with pivot; Bolt hole is set on rotor plate, and the tommyhead bolt that is slidingly arranged in the T-slot links to each other with rotor plate through bolt hole.
The above-mentioned circumscribed milling head of motor offset, the bottom and the upper part of the frame of motor cabinet are slidingly matched with arcwall face; The axis of said arcwall face is the axis of pivot.When rotor plate rotated around pivotal axis, motor cabinet slided along arcwall face simultaneously.This structure has strengthened the stability of motor, and vibration is little during work.
The above-mentioned circumscribed milling head of motor offset, support adopts body structure.The support of body structure, good rigidly.
The above-mentioned circumscribed milling head of motor offset, cutter spindle is vertical with pivot; The intersection point of the milling cutter surface of revolution and cutter spindle axis is positioned on the pivotal axis.Like this, during the adjustment lift angle, the height of milling cutter is constant, need not to readjust the height of milling cutter again.
The above-mentioned circumscribed milling head of motor offset, cutter spindle has the interior wimble structure that is used for the clamping knife bar.Like this, can clamping long handle knife bar machining internal thread in the cutter spindle.
