Description
Technical field
The present invention relates to hobboing cutter, particularly relate to a kind of split type hobboing cutter.
Background technology
Hobboing cutter is that cutter tooth makees the gear cutting tool of helical row along cylinder or circular cone, for by generating work Cylinder Gear
Wheel worm gear and other cylindrical toothed workpiece.According to the difference of purposes, hobboing cutter is divided into that gear hob worm gear hob is non-gradually to be left
Line becomes hobboing cutter and single position hob etc..China Patent No. be 2014207560086, Authorization Notice No. be CN204248238U, name
It is referred to as a kind of existing hobboing cutter disclosed in the patent documentation of " a kind of increasing footpath hobboing cutter processing ZCL turbine ".The basic structure of hobboing cutter
Including cutter hub and handle of a knife, cutter hub and the handle of a knife of existing hobboing cutter is structure as a whole (hereinafter referred to as one hobboing cutter) or is welded to connect
(hereinafter referred to as welding hobboing cutter) together, monoblock type hobboing cutter is due to its physique higher (doubling than welding hobboing cutter), therefore a lot of cuttves
Tool factory uses handle of a knife to be processed 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: one price of solid hob is 20000 yuan, and welds hobboing cutter and only need 10000 yuan, but welding hobboing cutter is due to can not coating
(brazed shank tool coating easily ftractures), therefore cutter life is the lowest, processes about 100 worm gears and just needs reconditioning again, more tool changing
Tool and debugging bring the biggest waste.
Summary of the invention
The invention provides a kind of cutter hub and handle of a knife can be fabricated separately and cutter hub coating does not allows caducous split type rolling
Cutter, solves existing split type hobboing cutter and uses and be welded to connect and the cutter hub coating that causes is easy to fall off causes short asking in service life
Topic.
More than technical problem is that and solved by following technical proposal: a kind of split type hobboing cutter, including cutter hub and handle of a knife, its
Being characterised by, also including that blind rivet, described cutter hub are provided with connection post, the end face of described connection post is provided with connection screwed hole, described cutter
Handle is provided with connection through hole, and described connection post cone match is plugged on one end of described connection through hole, and described blind rivet is from described connection
Described cutter hub and handle of a knife are detachably connected in penetrating and be threaded in described connection screwed hole by the other end of through hole.
The cutter hub of the present invention and handle of a knife are by using blind rivet to strain after cone match, thus avoid the cutter hub being welded to connect and cause and be coated with
The caducous problem of layer.And change connected mode and the applicable different cutter hub of same handle of a knife is connect, during cutter buying
Only need to purchase cutter hub, cutter hub price is the most cheap half than former brazed shank tool, is as above lifted this cutter hub and only needs 5000 yuan
(be i.e. equivalent to existing integral type price 1/4th) such that it is able to ensureing cost of charp tool first mate's degree on the premise of quality
Reduce.
As preferably, described connection screwed hole includes that inner segment and outer section, the outer end of described inner segment are provided with big footpath section, described greatly

Detailed description of the invention
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
Embodiment one, sees Fig. 1, and 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 connecting post 8 is provided with connection screwed hole 81.Handle of a knife 2 is provided with connection through hole 21.Connect post 8 pattern taper fit grafting
In the one end connecting through hole 21.Blind rivet 3 is left hand thread.Blind rivet 3 penetrates from the other end connecting through hole 21 and is threaded in
In connecting screwed hole 81, cutter hub 1 and handle of a knife 2 are detachably connected.
Embodiment two, with the difference of embodiment one be: 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.It is located in rotationally 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 coming directly towards 821 and coming directly towards drive mechanism 822.Top 821 is arranged on outer section 812
In.Top drive mechanism 822 includes that the first driving post 8221 and second drives post 8222.First drives post 8221 and second to drive
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.Middle connection through hole 21 is run through in operation hole 22.Action bars 23 it is equipped with in operation hole 22.
Seeing Fig. 3, pendulum groove 814 has three, and yaw 815 also wants three accordingly.Put the week that groove 814 is along outer period 812 for three
To distribution.It is designed with helix alignment's maintaining body 82 between all yaws and pendulum groove.Turn clockwise according in figure for outer section 812
Move (blind rivet is also screwed into rotationally clockwise) yaw 815 according in figure to be connected to a side of sidewall portion 8141 of pendulum groove
Time together, produce between another side of sidewall portion 8142 of yaw 815 and pendulum groove and swing gap 83, the screw thread of inner segment 811 and outer section 812
Screw thread be positioned on same helix.
Seeing Fig. 4, top drive mechanism 822 also includes driving post fastening screw 8224, inserting spring 8223 and drive post
Depart from spring 825.Post fastening screw 8224 is driven to be positioned at big footpath section 813 and be inserted in yaw 815.Insert spring
8223 are positioned at big footpath section 813.
See Fig. 2 to Fig. 4, when being screwed on blind rivet, the screw thread of inner segment 811 and the screw thread automatic aligning of outer section 812 and be positioned at
On same helix, it is enable to be screwed into easily.
Back-out blind rivet time, press the first drive rod 8221 by action bars 23, the first drive rod 8221 drives top 821 to stretch
Enter to the side of sidewall portion by being connected on another side of sidewall portion 8142 of pendulum groove make yaw 815 same pendulum groove in swinging gap 83
8141 are connected to together and make the screw thread of inner segment 811 and the helix alignment of outer section 812 and be positioned on same helix, now exist
Insert and under the effect of spring 8223, drive post fastening screw 8224 to be inserted in the first driving post 8221, make the first driving post
8221 are maintained at current state (will come directly towards the state being connected to put the position on another side of sidewall portion of groove).Make blind rivet of back-outing
Time the most laborsaving.
During duty, pressing the second driving post 8222, second drives post 8222 to drive post fastening screw 8224 to take off
Drive post 8221 from first, drive post to depart from spring 825 and drive the first driving post 8221 to eject and lose the driving to top 821
Act on and make to drive post fastening screw 8224 can not be inserted in the first driving post 8221.Outer section 812 and inner segment 811
Between can relatively rotate, vibrated and cause blind rivet with connect screwed hole have the trend of disengaging time, outer section 812 and inner segment
The rotation of 811 can cause the screw thread of the two to stagger, thus stops the generation of abjection.
