Between rear knife edge 4, the front cutting edge 3, adjustment block 5, the combination of rear knife edge 4 form cutter 10;
The upper surface of cutterhead 1 is provided with capping 7, and sliding block 2 is sealed in chute 15 by the capping 7;In the capping 7
Meta, which is installed, is equipped with round ring boss 71, the taper sheath 8 be located at round ring boss 71 in, and with the inner chamber of round ring boss 71
Matching;
Rotation top cover 9 is set on the round ring boss 71;The rotating shaft 11 passes through rotation top cover 9;The rotation top cover 9
The outer ring screw thread of inner ring and round ring boss 71 coordinate, the interior intracavitary of the rotation top cover 9, which is provided with, holds out against boss 91, described
Hold out against the upper end that boss 91 holds out against taper sheath 8.
The adjustable curved tooth cylindrical gear process tool of Gear Processing modulus of the present invention, during use:
First as shown in fig. 7, front cutting edge 3 to be fixed on to the lower surface of cutterhead 1, then according to needed on workpiece 20 processing
The modulus of curve tooth, chooses corresponding adjustment block 5, then adjustment block 5 is inserted into through hole 12, and fixed block 51 is consolidated
It is scheduled in adjustment block fixing groove 14, then rear knife edge 3 is fixedly mounted in the blade mounting seat 21 of sliding block 2;Then by twisting
Dynamic rotation top cover 9, because the outer ring screw thread of the inner ring and round ring boss 71 that rotate top cover 9 coordinates, therefore turns rotation top cover 9
It can move up and down.Moved down by turning rotation top cover 9 so that rotating top cover, so that promote taper sheath 8 to move down, taper
Set passes through the cooperation of circular conical surface 81 on taper sheath 8 and the top-surface camber 22 of sliding block 28 during moving down so that sliding block 2 to
The outer Slideslip of cutterhead 1, so as to drive rear knife edge 4 to slide, finally holds out against adjustment block 5 so that front cutting edge 3, adjustment block 5 and after
The formation cutter 10 of blade 4.After the completion of regulation, workpiece 20 is processed by rotary head 1.The workpiece 20 can be
