Specific embodiment
As shown in Figures 1 to 5, specific embodiment of the present utility model is:
The utility model includes a kind of hob-cutter structure, and the hob-cutter structure 1 includes the hobboing cutter main body 3 with inner cavity 2, described
Several straight-line grooves 4 for being connected to 3 lateral surface of hobboing cutter main body are provided in inner cavity 2.In the present solution, hob-cutter structure 1 passes through
Design straight-line groove 4 makes so that 1 outside of hob-cutter structure is communicated with inner cavity 2, it is therefore intended that can be from inner cavity 2 along straight for cutting oil
Wire casing 4 is sprayed and is prepared, and when carrying out gear 14 and processing, the supply of cutting oil is necessarily timely if cutting oil is sprayed from inner cavity 2
Effectively, so as to improve machining accuracy, extend cutter life.
Further, the middle line of the straight-line groove 4 and the central axes of the inner cavity 2 are perpendicular.
Further, several straight-line grooves 4 divide the two layers and every layer straight-line groove 4 to be uniformly arranged by circumference array.
The utility model further includes a kind of gear-hobbing machine using the hob-cutter structure, and the gear-hobbing machine includes the hobboing cutter knot
Structure 1, the hob rod 5 matched with the hob-cutter structure 1 and the hobboing cutter axle sleeve 6 matched with the hob rod 5, the hobboing cutter axis
Set 6 includes shell and middle swivel 8, and the external side of the hobboing cutter axle sleeve 6 is connected with oil feeder, the inside of the hobboing cutter axle sleeve 6
Middle part is provided with oily storage tower 7, is provided with a circle input oil groove 9 between the oil storage tower 7 and the lateral wall of the middle swivel 8,
The connector 10 of oil feeder is connected with the input oil groove 9, and the middle part of the hob rod 5, which is provided with, is connected to the oily storage tower
7 oil transportation channel 11, the oil transportation channel 11 are connected to the straight-line groove 4.In the present solution, oil feeder connector 10 with it is defeated
Oil groove 9 is connected, and input oil groove 9 can be docked and connected always with the connector of oil feeder 10, cut in entire middle 8 rotation of swivel
It cuts after oil is injected from oil feeder and passes sequentially through input oil groove 9, oil transportation channel 11 to last straight-line groove 4 injects to hob-cutter structure 1
At blade, this gear-hobbing machine pass through projected inside hob-cutter structure 1 cutting oil and can be cut with effective supply it is oily to cutting position, from
And it solves the problem of the precision of deficient oil supply in the prior art and gear hobbing process and declines the reduction of cutter life.
Further, the top of the hob-cutter structure 1 is provided with oil supply auxiliary block 12, the oil supply auxiliary block 12
Lower part is provided with semi-circular groove 13 compatible with the hob-cutter structure 1.In the present solution, as shown in figure 4, design has semicircle
The oil supply auxiliary block 12 of shape slot 13, can make the cutting oil sprayed from hob-cutter structure 1 collect in semi-circular groove 13, prevent
It splashes, meanwhile, as shown in Fig. 4 arrow direction, the injection approach for cutting oil can be patted on 13 surface of semi-circular groove, and cutting oil is suitable
Side leave to be located at its underpart cutting position, so as to make full use of cutting oil.
In this embodiment, hobboing cutter axle sleeve 6 designs input oil groove 9, and hob rod 5 designs oil transportation channel 11, hob-cutter structure 1
Straight-line groove 4 is designed, external oil feeder is allowed to input cutting oil and successively from hobboing cutter axle sleeve 6, hob rod 5, hob-cutter structure 1
Cutting position is flowed to, the cutting oil flowed out on the inside of 4 bottom of cutting blade ditch of hob-cutter structure 1 is to progress fuel feeding, fuel feeding from hobboing cutter point of a knife
Arrow direction in approach such as Fig. 4 uses which to carry out gear hobbing process effect good quality high, tool bit life.
Hob-cutter structure 1 can give full play to its effect when processing wide-angle gear 14, due to pitch face, interfere few therefore cut
The cutting oil at the place of cutting can be carried out effective supply, thus can be reduced the concave-convex phenomenon of the flank of tooth after processing, improve gear to reach
The purpose of precision.In addition, air stream of the hob-cutter structure 1 when revolution at a high speed is processed does not interfere the supply for cutting oil at cutting；
In the occasion that the bigger Gear Processing of rake angle and revolution at a high speed are processed, the effective supply of cutting oil also can be carried out, to reach
To cooling, the effect of lubrication.Because cutting the effective supply of oil, to generate cooling at cutting, lubrication and effectively exclusion are cut
The effect of powder, thus the working durability of hobboing cutter blade can be extended.
This hob-cutter structure 1 can be in terms of gear hobbing process, and the helical teeth processing industry having any problem from outer injection cutting oil can be wide
General utilization, alternatively, it is also possible to be used in hobboing cutter revolution at a high speed machining industry.
The utility model can be used for the technical field of gear-hobbing machine.
