Description
Technical field
The utility model belongs to machined components field, and in particular to be a kind of lock dentition formula conical surface lathe tool.
Background technology
Lathe tool is the cutter for turnery processing, with a cutting tip.Groundwork is exactly that generation and processing are cut
The part of bits, including blade, make chip break it is broken or wind up structure, chip removal or hold the storage space of chip, the passage etc. of cutting fluid
Structural element.
It can be divided into overall lathe tool, brazed carbide turning tool, mechanically-clamped turning tool, parting-off tool, indexable turning tool and shaped profile turning cutter by structure.
The application of wherein indexable turning tool is increasingly extensive, and proportion gradually increases in lathe tool.
Parting-off tool cuts both narrow and deep groove, and chip space is small, and chip easily blocks, in order to reduce same machined surface
Friction, the both sides of its cutting tip must grind auxiliary angle, thus the intensity of root weakens significantly.In addition, parting-off tool is being cut
When at nearly workpiece centre, cutting speed levels off to zero, is unfavorable for cutting.Therefore, parting-off tool easily " is forged a knife " (collapse at work
Split).Main cutting edge is typically made herringbone by advanced parting-off tool, before wear into ridge-shaped, make chip produce cross-direction shrinkage,
Stably discharge, will not be blocked in groove in one direction, while bowing is made in cutter head bottom again, to carry to greatest extent
High intensity and rigidity
Formed turning tool is the dedicated tool for processing revolving body profiled surface, and its tooth shape is designed according to workpiece profile, can
With on all kinds of lathes processing in external gyrorotor profiled surface.Parts list can be once formed when processing part with formed turning tool
Face, it is easy to operate, productivity ratio is high, grade of tolerance IT8~IT10 can be reached after processing, roughness is 10~5 μm, and can guarantee that compared with
High interchangeability.But formed turning tool manufacture is more complicated, cost is higher, and blade operative length is wider, therefore easily causes vibration.Shape car
Knife be used primarily in manufacturing batch it is larger in, part of the small size with profiled surface.
And current welding entirety lathe tool is all in the prevalence of the admittedly easy sealing-off of not prison welding, technique for welding complexity, tungsten
Steel material price height, the wasting of resources, special bar is special does not have the shortcomings that versatility.
Utility model content
In order to solve the above technical problems, the utility model, which provides one kind, realizes a kind of knife bar multiple use, a variety of knives
Head exchanges combination, the low kind lock dentition formula conical surface lathe tool of production cost.
To achieve the above object, the technical solution adopted in the utility model is one kind lock dentition formula conical surface lathe tool, including knife bar
And lathe tool, its structural feature are, lathe tool includes screw head and cutter head, screw head and cutter head made of the high-quality high-speed steel of high intensity
It is integrally formed, screw head is removably connected with knife bar, and blade is removably connected with cutter head, and screw head and cutter head are that section is
Triangle is set.
As preferred scheme of the present utility model, screw head and the end face of knife bar connection end are provided with blind hole, and knife bar is plugged in
In blind hole.
As preferred scheme of the present utility model, screw head and the side face of knife bar connection end are provided with through the first of blind hole
Through hole.
As preferred scheme of the present utility model, knife bar is provided with the side face of screw head connection end and is adapted to first through hole
The second through hole.
As preferred scheme of the present utility model, screw head is connected with knife bar by taper, and taper is plugged in first through hole
In the second through hole.
As preferred scheme of the present utility model, taper is provided with screwed hole, and screw is provided with screwed hole.
The beneficial effects of the utility model are：It is reasonable in design, it is simple in construction, a kind of knife bar multiple use is realized, it is a variety of
Cutter head exchanges combination, and production cost is low, and assembling is quick, improves production efficiency, economizes on resources.
