Description
Technical field
The utility model belongs to process tool technical field, relates to one and rolls slotting tool.
Background technology
Present stage transferring power and the mechanical organ of motion in, gear is one of modal element, it is widely used in the transmission of various power, in the transmission of the large power such as boats and ships, automobile, aircraft, or the power transmission of the large-scale facility such as heavy machinery, machining facility, and even in the small-sized machine such as electrical home appliances, wrist-watch using in daily life or electronic equipment, all can see the example of gear application.Gear comprises external gear and internal gear, uses different gear working machines man-hour external gear wheel and internal gear are processed respectively adding.In order to utilize same gear working machine external gear wheel and internal gear to process, need to use the special processing head of external gear or the special processing head of internal gear, processed complex, operating efficiency are low.For this reason, Gear Processing by employing roll, Gear Shaping till now operative gear adopt new technology with rotational indexing machining principle machining gears.Adopt this new technology machining gears, can be with straight-tooth roll the inside and outside helical gear of plunge tooling; Can roll the inside and outside spur gear of plunge tooling, helical gear with the helical teeth of different helical angles, process velocity is fast, and efficiency is high.But also there is no a kind of slotting tool that rolls that meets new technology, new machine processing request.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of reasonable in design, the easy to process slotting tool that rolls.
The purpose of this utility model can realize by following technical proposal:
Originally roll slotting tool, comprise the discoid cutter hub with endoporus, it is characterized in that, on the periphery wall of described cutter hub, there is the cutting teeth of some employing spatial intersecting axle theory of engagement designs, described cutting teeth comprises cutter tooth side, cutter tooth lip surface and cutter tooth end face, and the top relief angle of described cutting teeth is α, and the span of described α is 7 °-12 °, the side edge relief angle of described cutting teeth is β, and the span of described β is 2 °-4 °.
Employing is different from the helical angle machining gears of gear, and for avoiding rotational indexing machining to interfere, top relief angle is 7-12 °, and side edge relief angle is 2 °-4 °, and cutter tooth width is narrower, and its width is 8-15mm, and the cutter tooth on each cutter hub is more.Cutting teeth in this structure can be designed to helical teeth, also can be designed to straight-tooth, all can process spur gear and helical gear.
Above-mentioned rolling in slotting tool, the laterally inclined setting of described cutter tooth, the angle between described cutter tooth lip surface and the radial line of cutter hub is γ, described γ is 5 °.Cutter tooth lip surface is obliquely installed, is adding the feeding that facilitates cutting teeth man-hour.
Above-mentioned rolling in slotting tool, between described cutter tooth end face and cutter tooth side, be provided with rounding R.
Above-mentioned rolling in slotting tool, on described cutter hub, have and the coaxial layer hole arranging of above-mentioned endoporus, the diameter in described layer hole is greater than the diameter of endoporus.Cutter hub is installed on handle of a knife adding man-hour requirement, needs bolt that cutter hub is fixed on handle of a knife.
Above-mentioned rolling in slotting tool, described cutting teeth is made up of PM HSS.
Compared with prior art, originally rolling slotting tool has the following advantages:
Adopt this to roll slotting tool and coordinate new technology machining gears, can with straight-tooth roll the inside and outside helical gear of plunge tooling, can roll the inside and outside spur gear of plunge tooling, helical gear with the helical teeth of different helical angles, process velocity is fast, efficiency is high.

Detailed description of the invention
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiment.
As shown in Figure 1 roll slotting tool, comprise the discoid cutter hub 1 with endoporus 11, as depicted in figs. 1 and 2, on conductor, be also provided with layer hole 12, this layer of hole 12 coaxially arranges with endoporus 11, and the diameter in layer hole 12 is greater than the diameter of endoporus 11.Originally roll slotting tool, cutter hub 1 is installed on handle of a knife adding man-hour requirement, just need bolt that cutter hub 1 is fixed on handle of a knife, layer hole 12 is mainly used for holding the club head portion of bolt.
As depicted in figs. 1 and 2, on the periphery wall of cutter hub 1, there is the cutting teeth 2 of some employing spatial intersecting axle theory of engagement designs, in the present embodiment, as shown in Figure 2, cutting teeth 2 be 49, cutting teeth 2 comprises cutter tooth lip surface 21, cutter tooth side 22 and cutter tooth end face 23.
As shown in Figure 1, the top relief angle of cutting teeth 2 is α, and the span of α is 7 °-12 °, and as shown in Figure 4, the side edge relief angle of cutting teeth 2 is β, and the span of β is 2 °-4 °.Employing is different from the helical angle machining gears of gear, and for avoiding rotational indexing machining to interfere, top relief angle is 7-12 °, side edge relief angle is 2 °-4 °, cutter tooth width is narrower, and its width is 8-15mm, and the cutter tooth on each cutter hub 1 can be selected the different numbers of teeth according to the number of teeth of machining gears.
As shown in Figure 1, the angle between cutter tooth lip surface 21 and the radial line of cutter hub 1 is γ, and γ is 5 °, and cutter tooth lip surface 21 is obliquely installed, and is adding the feeding that facilitates cutting teeth 2 man-hour.As shown in Figure 3, between cutter tooth end face 23 and cutter tooth side 22, be provided with rounding R.
