Description
Technical field
The present invention relates to hobboing cutter, more particularly to a kind of split type hobboing cutter.
Background technology
Hobboing cutter is the gear cutting tool that cutter tooth makees helical row along cylinder or circular cone, for by generating work Cylinder Gear
Take turns ﹑ worm gears and other toothed workpiece of cylinder.According to the difference of purposes, hobboing cutter is divided into that Chi wheel Gun Dao ﹑ Wo wheel Gun Dao ﹑ are non-gradually to be opened
Line is into hobboing cutter and single position hob etc..China Patent No. be 2014207560086, Authorization Notice No. CN204248238U, name
A kind of existing hobboing cutter referred to as disclosed in the patent document of " a kind of increasing footpath hobboing cutter of processing ZCL turbines ".The basic structure of hobboing cutter
Including cutter hub and handle of a knife, the cutter hub and handle of a knife of existing hobboing cutter are structure as a whole（Hereinafter referred to as integral hobboing cutter）Or it is welded to connect
Together（Hereinafter referred to as weld hobboing cutter）, monoblock type hobboing cutter is higher due to its physique（Doubled than welding hobboing cutter）, therefore many knives
Tool factory is processed using handle of a knife with cutter hub welding manner, and its handle of a knife is different from cutter hub material therefor, can reduce the cost of charp tool,
Such as：Solid hob one is 20000 yuan price, and welding hobboing cutter only needs 10000 yuan, but welds hobboing cutter due to being unable to coating
（Brazed shank tool coating easily ftractures）, therefore cutter life is very low, 100 or so worm gears of processing just need reconditioning again, more tool changing
Tool and debugging bring very big waste.
The content of the invention
It can be fabricated separately the invention provides a kind of cutter hub and handle of a knife and cutter hub coating not allow caducous split type rolling
Knife, solve existing split type hobboing cutter and cause service life is short to ask using cutter hub coating is easy to fall off caused by being welded to connect
Topic.
Above technical problem is that solved by following technical proposal：A kind of split type hobboing cutter, including cutter hub and handle of a knife, its
It is characterised by, in addition to blind rivet, the cutter hub are provided with connecting pole, the end face of the connecting pole is provided with connection screw thread hole, the knife
Handle is provided with connection through hole, and the connecting pole cone match is plugged on one end of the connection through hole, and the blind rivet is from the connection
The other end of through hole is penetrated and is threaded in the connection screw thread hole and the cutter hub and handle of a knife are detachably connected.
The present invention cutter hub and handle of a knife by after cone match use blind rivet tense, so as to avoid be welded to connect caused by cutter hub apply
The caducous problem of layer.And change connected mode so that the applicable different cutter hub of same handle of a knife is coupled, when cutter is purchased
Only cutter hub need to be purchased, cutter hub price half again cheaper than the brazed shank tool of original, as above lifting this cutter hub only needs 5000 yuan
（That is, a quarter of the price of existing integral type）, so as to cost of charp tool first mate's degree on the premise of quality is ensured
Reduce.

Embodiment
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
Embodiment one, referring to Fig. 1, a kind of split type hobboing cutter, including cutter hub 1, handle of a knife 2 and blind rivet 3.Cutter hub 1 is provided with connection
Post 8.The end face of connecting pole 8 is provided with connection screw thread hole 81.Handle of a knife 2 is provided with connection through hole 21.The pattern taper fit grafting of connecting pole 8
In one end of connection through hole 21.Blind rivet 3 is left hand thread.The other end of blind rivet 3 from connection through hole 21 is penetrated and is threaded in
Cutter hub 1 and handle of a knife 2 are detachably connected in connection screw thread hole 81.
Embodiment two, the difference with embodiment one are：Cutter hub 1 also includes helix alignment's maintaining body 82.Connect spiral shell
Pit 81 includes inner segment 811 and outer section 812.The outer end of inner segment 811 is provided with big footpath section 813.The perisporium of big footpath section 813 is provided with pendulum
Groove 814.It is provided with yaw 815 for outer section 812.Rotationally it is located in for outer section 812 in big footpath section 813.Yaw 815 is plugged on pendulum groove
In 814.
Helix alignment's maintaining body 82 includes top 821 and top drive mechanism 822.Top 821 is arranged on outer section 812
It is interior.Coming directly towards drive mechanism 822 includes the first driving driving post 8222 of post 8221 and second.First driving post 8221 and second drives
Post is arranged in yaw 815, and stretches out the outer face of outer section 812.
Handle of a knife 2 is provided with operation hole 22.Operation hole 22 is through middle connection through hole 21.Action bars 23 is equipped with operation hole 22.
Referring to Fig. 3, pendulum groove 814 has three, and accordingly yaw 815 also wants three.Three are put grooves 814 along outer section 812 of week
To distribution.Helix alignment's maintaining body 82 is designed between all yaws and pendulum groove.Turn clockwise according in figure for outer section 812
Move（Blind rivet is also according to being screwed into rotationally clockwise in figure）Yaw 815 is connected to a side of sidewall portion 8141 of pendulum groove
When together, generation swing gap 83, the screw thread of inner segment 811 and outer section 812 between yaw 815 and another side of sidewall portion 8142 for putting groove
Screw thread be located on same helix.
Referring to Fig. 4, top drive mechanism 822 also includes driving post fastening screw 8224, insertion spring 8223 and driving post
Depart from spring 825.Driving post fastening screw 8224 is in big footpath section 813 and is inserted into yaw 815.Insert spring
8223 in big footpath section 813.
Referring to Fig. 2 to Fig. 4, when being screwed on blind rivet, the screw thread of inner segment 811 and outer section 812 of screw thread automatic aligning and be located at
On same helix, it is enable to easily be screwed into.
When back-outing blind rivet, the first drive rod 8221 is pressed by action bars 23, the first drive rod 8221 driving top 821 is stretched
Enter to by swinging in gap 83 and be connected to a side of sidewall portion of the same pendulum groove of yaw 815 on another side of sidewall portion 8142 of pendulum groove
8141 abut together and cause inner segment 811 screw thread and outer section 812 of helix alignment and on the same helix, now exist
Driving driving post fastening screw 8224 is inserted into the first driving post 8221, makes the first driving post in the presence of insertion spring 8223
8221 are maintained at current state（The state for the position being connected on another side of sidewall portion of pendulum groove will be come directly towards）.So that back-out blind rivet
When also easily it is laborsaving.
During working condition, the driving post 8222, second of pressing second drives the driving driving post fastening screw 8224 of post 8222 de-
From the first driving post 8221, driving post departs from the driving of spring 825 first driving post 8221 and ejects and lose the driving to top 821
Act on and driving post fastening screw 8224 can not be inserted into the first driving post 8221.Now outer section 812 and inner segment 811
Between can relatively rotate, it is vibrated and when causing blind rivet to have the trend of disengaging with connection screw thread hole, outer section 812 and inner segment
811 rotation can cause the screw thread of the two to stagger, so as to prevent the generation of abjection.
