Technical solution of the present invention: it is a kind of for processing the pinion cutter for jumping tooth involute internal spline gear shape, it include knife handle
Bar, the shank of knife handle bar one end are Mohs cone, and the other end of knife handle bar is equipped with outer circle, and are equipped with flat A in outer circle, outer circle with
The inner hole of cutter head connects.
It is previously described for processing to jump in the pinion cutter of tooth involute internal spline gear shape, the outside of the cutter head is equipped with a circle and inserts
Pin tooth, in order to during gear shaping avoid be processed internal spline on jump tooth, remove on the outside of cutter head a latch hook from
And hypodontia is formed, and cutter head is equipped with the flat B of correspondingly-sized on the inner hole cooperated with A flat in outer circle, prevent cutter head and knife handle bar
It relatively rotates.
The processing method of the pinion cutter for processing jump tooth involute internal spline gear shape, includes following steps；
A, shank Mohs cone one end of pinion cutter is connect with shaping machine, while part is connected on shaping machine；
B, shaping machine drives pinion cutter and parts turn respectively, and shaping machine drives the knife handle on pinion cutter through Mohs cone
The other end of bar, knife handle bar is equipped with outer circle, is equipped with the flat B of correspondingly-sized on the inner hole cooperated with A flat in outer circle in cutter head
Under the action of, knife handle bar band dynamic cutter head rotates, and carries out Gear Shaping, is formed on part and jump tooth involute inner spline.
It is previously described in the processing method for the pinion cutter that tooth involute internal spline gear shape is jumped in processing, in the step B, inserts
Tooth lathe drives the revolving speed of pinion cutter and parts turn identical.
It is previously described in the processing method for the pinion cutter that tooth involute internal spline gear shape is jumped in processing, in the step B, inserts
Tooth processing is that part is often rotated by 360 °, i.e. when a feed, pinion cutter is simultaneously rotated 360 °, this makes lacking on pinion cutter cutter head
The position of tooth and the jump tooth on part internal spline is completely coincident, and realizes that the jump tooth on part internal spline is not cut.
Compared with prior art, the invention has the following advantages:
1, the structure of Special Slotting Cutters
Gear Shaping can be smoothly completed in order to ensure jumping tooth internal spline, according to tooth profile parameter (number of teeth, modulus, the pressure of internal spline
Angle) and used shaping machine (spindle hole specification), designed, designed Special Slotting Cutters are mainly by knife handle bar and cutter head two
Part forms, and key is to remove a latch hook in cutter head latch hook to form hypodontia, to get out of the way the jump on internal spline
Tooth is allowed to not be cut (such as processing conditions allows, and can do knife handle bar and cutter head integral), and structure is as shown in Figures 3 and 4；
1, the main function of knife handle rod structure
The shank of knife handle bar one end is Mohs cone, and shank Mohs cone one end is connect with shaping machine, the other end of knife handle bar
It is equipped with outer circle, and is equipped with flat A in outer circle, prevents cutter head from relatively rotating with knife handle bar, the inner hole connection of outer circle and cutter head,
Specific size can as needed depending on, structure is as illustrated in Figures 5 and 6；
3, the main function of cutter head structure
The main function of cutter head is to complete internal spline tooth form shaping, is processed on internal spline to avoid during gear shaping
Jump tooth (not processing tooth), remove a latch hook on the outside in cutter head to forming hypodontia；And cutter head in outer circle
The inner hole of flat A cooperation is equipped with the flat B of correspondingly-sized, prevents cutter head from relatively rotating with knife handle bar, specific size and parameter
Can as needed depending on, structure is as shown in FIG. 7 and 8；
4, for processing the processing method for jumping the pinion cutter of tooth involute internal spline gear shape
Shank Mohs cone one end of pinion cutter is connect with shaping machine, while part being connected on shaping machine, gear shaping
Lathe drives pinion cutter and parts turn, and shaping machine drives the revolving speed of pinion cutter and parts turn identical, is processed, and
Gear Shaping is that part is often rotated by 360 °, i.e. when a feed, simultaneously as shaping machine drives pinion cutter and parts turn
Revolving speed is identical, and pinion cutter is simultaneously rotated 360 °, this makes the position of the hypodontia on pinion cutter cutter head and the jump tooth on part internal spline
Set and be completely coincident, guarantee internal spline on jump tooth be not cut, realize to part carry out jump tooth involute inner spline processing, zero
Part structure is as illustrated in fig. 1 and 2, and method is simple, easy to use.
5, it is existing for need with spline orient (tooth is skipped not process, using the tooth as orient build) when, spline
Tooth form it is discontinuous, shape is as shown in Fig. 2 K- K section, when processing such spline, according to conventional Gear Shaping method,
It is difficult to tripping and does not process tooth, be the processing for being unable to complete such internal spline, our factory is initially to process week using manually being processed
Phase is long, and be easy to cause the damage of cutter, difficult for the tooth Profile Machining of the internal spline, and tooth form is difficult to meet processing request,
Easy to use since its method is simple but after using method of the invention, the manufacturing batch for being able to achieve such internal spline is raw
It produces.
In conclusion the present invention be suitable for jumps tooth be a tooth internal spline Gear Shaping, multinomial orientation valve rod with
It is promoted the use of in drive rod, method is simple, and it is easy to use, to the beneficial effect for saving processing cost important role
Fruit.
