Description
Technical field
Machining equipment is the utility model is related to, more particularly to a kind of spling hob.
Background technology
Manufacture and design field in spling hob, generally there are two kinds of structures of worm gear hob and spling hob with holes, by product knot
Structure (such as oil pump tooth axle) constrains, and to ensure spline effective length during processing, spling hob excircle dimension is larger, and annular knurl key enters
During row ending operation, the endface position of workpiece will be rolled into, the end face of some products is installation oil sealing, if rolling on spline rolling
Knife tool marks, will draining, do not have sealing function；The few spling hob with holes of the small number of teeth of product spline modulus that has in addition it is bad plus
Work, and can not be excessive to the cylindrical size requirement of cutter, if high using the tooling cost of worm gear arrangement, cutter tooth is once
Scrap, whole knife bar can not be used.
The content of the invention
To solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structural strength height, and is easy to tear open
The spling hob of replacing is unloaded, and solves the problems, such as lateral incision when annular knurl key finishes up.
To realize above-mentioned technical purpose, technical scheme is as follows used by the utility model.
A kind of Novel spline hobboing cutter, its mandrel for including being connected with machine output shaft, the spline being connected with mandrel output end
Hobboing cutter, the axle sleeve being connected with spling hob suspension end, axle sleeve are slidably mounted on lathe fixed position and can turned around own axes
Dynamic, spling hob is made up of hobboing cutter portion and the clamping part for being arranged at hobboing cutter portion both ends and being arranged with hobboing cutter portion coaxial line, core
Axle is connected end with spling hob and is provided with the hole slot to match with clamping part, and the hole to match with clamping part is provided with axle sleeve
Groove, it is bolted between mandrel and clamping part and between axle sleeve and clamping part.
The flat 15-25mm of clamping part milling, when carrying out locking positioning using bolt, improve stability；Above-mentioned hobboing cutter portion it is excellent
Select a length of 40mm of tooth.
Spling hob is made of W6Mo5Cr4v2 materials, and its hardness is strong, and wearability is good.
Compared with prior art, it is advantageous in that the utility model, spling hob with holes（As shown in Figure 1）It is cylindrical straight
When footpath is restricted, the intensity of its wall portion significantly reduces, and the scope of application significantly reduces；The utility model compared with prior art, can
The structural strength of spling hob is obviously improved, and possesses and is easily changed, the advantage such as replacement cost is low.
Brief description of the drawings
In order to illustrate the embodiments of the present invention more clearly, the required accompanying drawing used in embodiment will be done simply below
Introduce, it should be apparent that, drawings in the following description are only some embodiments of the present invention, for ordinary skill people
For member, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of spling hob with holes of the prior art.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is structural representation of the present utility model.
It is denoted as in figure：
10th, mandrel；
20th, spling hob；210th, hobboing cutter portion；220th, clamping part；
30th, axle sleeve.
Embodiment
With reference to the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Ground describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art are not under the premise of creative work is made, the every other reality that is obtained
Example is applied, belongs to the scope of the present invention.
Referring to accompanying drawing 2, a kind of Novel spline hobboing cutter is its mandrel 10 for including being connected with machine output shaft, defeated with mandrel 10
Go out the spling hob 20 of end connection, the axle sleeve 30 that end is connected is suspended with spling hob 20, axle sleeve 30 is slidably mounted on lathe and fixed
Position and can around own axis, spling hob 20 by hobboing cutter portion 210 and be arranged at the both ends of hobboing cutter portion 210 and with rolling
The clamping part 220 of the coaxial line arrangement of knife portion 210 is formed, and mandrel 10 is connected end with spling hob 20 and is provided with and clamping part 220
The hole slot to match, be provided with the hole slot to match with clamping part 220 on axle sleeve 30, between mandrel 10 and clamping part 220 and
It is bolted between axle sleeve 30 and clamping part 220.
For the locking positioning for spling hob 20 of being more convenient for, preferred pair clamping part 220 carries out the flat processing of milling, and clamping part 220 can
The flat about 20mm of milling, when carrying out locking positioning using bolt, improve stability；The a length of 40mm of preferred tooth in above-mentioned hobboing cutter portion 210.
Using Novel spline hobboing cutter provided by the utility model, when changing spling hob, hobboing cutter portion 210 is held on the other hand,
The bolt of the other hand loose ends can be changed quickly, and the costs such as it repairs, changed are lower.
Tool sharpening technical process：Saw material（Material is W6Mo5Cr4v2）→ car profile → cutting thread → groove milling → teeth →
Deburring tooth → heat treatment → grinding core handle guide pillar → puts the first edge on a knife or a pair of scissors → relief grinding → coating（Titanizing）, overall length 100mm, the length of cutter tooth 40 can meet
Need.
The foregoing description of the disclosed embodiments, professional and technical personnel in the field are enable to realize or using the present invention；
