Excision, is therefore unsatisfactory for using.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that
A kind of reasonable in design and the gear shaper cutter of tooth bar two ends boss can be retained.
The purpose of this utility model can be realized by following technical proposal: a kind of tooth bar is inserted
Serrated knife, including disc-shaped body, the middle part of described body is provided with the connecting hole run through,
It is characterized in that, if being provided with dry cutting continuously on the lateral wall of wherein one section of described body
Tooth, the lateral wall of described body remaining one section for allowing teeth portion, described cutting tooth
The theoretical number of teeth more than the number of teeth of manufacturing gear strip, the number of actual teeth of described cutting tooth and quilt
The groove number of manufacturing gear strip is identical, and the described diameter of teeth portion that allows is less than described cutting tooth
Root diameter.
Identical with the groove number of processed tooth bar by arranging the number of actual teeth of cutting tooth, tooth bar
The cutting tooth continuous distribution of pinion cutter is in the side of the lateral wall of body, and the root of cutting tooth
Footpath is less than the root footpath of normal pinion cutter, it is to avoid slotting interference of tooth, when manufacturing gear strip,
Avoid switching to tooth bar two ends high point during pinion cutter excision tooth root, retain two ends convex of tooth bar
Platform, has the advantage that design is relatively reasonable.
In above-mentioned a kind of gear shaper cutter, described body has another of cutting tooth
End is provided with side keyway, and described cutting tooth is centered by the center line of described side keyway
It is symmetrical arranged.By arranging side keyway, it is possible to be inserted into this tooth bar to have and preferably determine
Position effect, it is impossible to it circumferentially rotates, simultaneously when changing gear shaper cutter, it is not necessary to weight
Multiple location, saves the debugging time, improves productivity ratio.
In above-mentioned a kind of gear shaper cutter, the rectangular in cross-section of described side keyway.
In above-mentioned a kind of gear shaper cutter, described connecting hole is stepped hole, including
The taper hole being connected and straight hole, described side keyway is arranged on the one of described straight hole
Side.Connecting hole uses taper hole to combine with straight hole, has easy to connect and rational in infrastructure
Advantage.
In above-mentioned a kind of gear shaper cutter, the gradient of described taper hole be 0 ° extremely
15°。
Compared with prior art, this one gear shaper cutter has the advantage that
1, when manufacturing gear strip, it is to avoid switch to tooth bar two ends high point during pinion cutter excision tooth root,
Retain the boss at the two ends of tooth bar, there is the advantage that design is relatively reasonable；
2, by arranging side keyway, it is possible to be inserted into this tooth bar to have and preferably position effect
Really, it is impossible to it circumferentially rotates, simultaneously when changing gear shaper cutter, it is not necessary to it is fixed to repeat
Position, saves the debugging time, improves productivity ratio；
3, connecting hole uses taper hole to combine with straight hole, has easy to connect and rational in infrastructure
Advantage.

Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, to this utility model
Technical scheme be further described, but this utility model is not limited to these embodiments.
As shown in Figures 1 to 3, a kind of gear shaper cutter, including disc-shaped body 1,
The middle part of body 1 is provided with the connecting hole 2 run through, wherein on the lateral wall of one section of body 1
If being provided with dry cutting tooth 3 continuously, the lateral wall of body 1 remaining one section for allowing teeth portion 4,
The theoretical number of teeth of cutting tooth 3 is more than the number of teeth of manufacturing gear strip 6, the actual tooth of cutting tooth 3
Number is identical with the groove number of processed tooth bar 6, allows the diameter of teeth portion 4 be less than the tooth of cutting tooth 3
Root diameter.
Body 1 has the other end of cutting tooth 3 and is provided with side keyway 5, side keyway 5
Rectangular in cross-section, cutting tooth 3 be symmetrical arranged centered by the center line of side keyway 5.
Connecting hole 2 is stepped hole, including the taper hole 2a being connected and straight hole 2b, end
Face keyway 5 is arranged on the side of described straight hole 2b.The gradient of taper hole 2a be b be 0 °
To 15 °, as preferably, gradient be b be 6 °.Connecting hole 2 uses taper hole 2a
Combine with straight hole 2b, there is advantage easy to connect and rational in infrastructure.
It is identical with the groove number of processed tooth bar 6 by arranging the number of actual teeth of cutting tooth 3,
Tooth bar 6 pinion cutter cutting tooth 3 continuous distribution in the side of the lateral wall of body 1, and
The root footpath of cutting tooth 3 is less than the root footpath of normal pinion cutter, it is to avoid slotting interference of tooth,
