In specific embodiment of the utility model, implements the straight-tooth gear shaping device of the technical program, understand drawing first
It is required that, size, the number of teeth number with the depth of tooth, then the preparation before being processed, such as：1. workpiece is on fixture
Ensure when it being allowed to rotate concentric.2. customizing molding cutter by drawing size requirement.
After the completion of preparation, tune machine operation is carried out：1. machinery：To the point of a knife of good pinion cutter to workpiece surface, knife is being transported
The upper and lower point of every trade journey will be more than workpiece, and knife can not encounter fixture.2. arrange parameter：The number of teeth and tooth are set in a control program
Depth (damage of effect of depth cutter, workpiece deformation and the smoothness of workpiece surface) according to the material of workpiece and to workpiece
It is required that control the depth of tooth.
Workflow in processing：Parameter setting it is complete after press start key, the distance of pinion cutter point of a knife the first knife of alignment settings,
Point of a knife knife is entered by motor and lead screw full-automatic device the first knife set feed point (feed point as：To knife point and
The depth of one knife setting) set after, behind the motor of cam gear can start, toward being pushed forward after startup, band cutter and workpiece
It generates and cuts, after the workpiece that nuzzles up, inductor touches the induction point of former setting, and meeting withdrawing, falls back on after entire workpiece has been cut
Knife point safe distance (if apart from not far, knife is not withdrawn, turn next angle when cutter can collide, fall back on safety away from
Would not be damaged from knife and workpiece) cylinder drives while shrink back to former set point cutter cam gear turning always
Dynamic, rotation direction is to move back and forth, and having arrived this complete point (lower tooth point) knife of work pieces process can shrink back, what knife shrank back
Eccentric shaft can receive next signal (the 90 degree of direction cuttings of a circle point), cutter continues past also toward retracting simultaneously after retracting
Before walk, go to the distance (coordinate points originally set) of the second knife processing, subsequent motor continues to go ahead and (turning always)
Repeat the second knife of processing, depth down on the basis of first time, when the switch of inductive switching to 9 o'clock direction this
Knife just cuts and completes, and to continuing to shrink back, returns to knife point, prevents knife from damaging cutter and workpiece in card slot, after retracting
Eccentric wheel senses that the switch in 3 o'clock direction, knife continue to move forward, and enters the coordinate of the position of the third knife of former setting, cam
Device continues to walk, and third knife is processed the position that rear (only need to process three knives) cam gear sensed for 9 o'clock, three axis are simultaneously
(three axis are for rotation：1. being retreated into withdrawing, return to knife point；2. eccentric shaft falls back on the position at 3 o'clock of induction point toward retracting；
3. indexing means controls knife number of the cutter to work pieces process according to the angle of setting time-division, until work pieces process is completed).
Implement the utility model specific embodiment in scheme the characteristics of be：Double guiderail bases use hard rail, make workpiece table
Face is more smooth than the pedestal of other tracks.2, pushing meanss use eccentric wheel apparatus, not will produce in pushing course pause,
Gap keeps workpiece smoothness higher, tooth form more stable.It may be implemented：The feature that speed is fast, precision is accurate receives 3 in that is, one minute
Signal, 265 detections signal per minute, it is subsequent into tool retracting device to feed back to motor, indexing means operation in one minute 265 times into
Row indexing positioning.
