Abstract
The invention discloses a kind of ladder aperture knife tools, it belongs to cutter field, including step tool ontology, step tool ontology is mounted on handle of a knife, step tool body interior is equipped with hollow channel, the front end of step tool ontology of the present invention is fixed with jacking block, jacking block is equipped with apopore and is connected to hollow channel, several knife-edge leading ends of step tool rear body are also equipped with apopore connection hollow channel, several apopores are respectively sprayed to backwards from the immediate blade of step tool ontology described in its, the present invention carries out cooling injection using the apopore of knife-edge leading end to blade, not only reduce the temperature of blade, but also it can help to the discharge of iron filings discharge direction, substantially increase the processing quality of stepped hole.
Description
Technical field
The present invention relates to cutter fields, and in particular to a kind of ladder aperture knife tool.
Background technology
The processing sequence of stepped hole is three roughing, semifinishing and finishing processes, is processed in roughing straight
Hole, when semifinishing, process stepped hole, and stepped hole is further processed in finishing.
Plain bore is different to the processing of high request stepped hole, to cylindricity, concentricity, roughness requirement all very
Height carries out cold step tool in current the study found that current apopore is usually towards blade direction or is court
The chip removal direction at blade rear, purpose, the former be in order to timely cool down blade, blade be avoided to cross thermosetting built-up edge,
However due to rebound of the discharge pressure through via bottom, hydraulic pressure reduction can cause the efficiency of chip removal influence, the latter be in order to
Timely chip removal avoids iron filings from hindering chip removal and improves thermal diffusivity, while can be cooled down to blade, but at this time cooling water by
Iron filings heat, and are unfavorable for the cooling of blade, and since iron filings are impacted at blade, iron filings are impacted to tool sharpening,
The surface gray scale of later stage stepped hole is impacted.
In view of the above-mentioned problems of the prior art, the design and use experience of present invention combination related field for many years,
It is aided with too strong professional knowledge, has manufactured and designed a kind of ladder aperture knife tool, to overcome drawbacks described above.
Invention content
For the problems of in the prior art, a kind of ladder aperture knife tool provided by the invention can ensure knife
The timely cooling of sword, while chip removal efficiency is further increased, avoid iron filings from interfering the processing of blade.
To achieve the goals above, the technical solution adopted by the present invention is as follows：A kind of ladder aperture knife tool, including ladder
Cutter body, the step tool body interior are equipped with hollow channel, and the front end of the step tool ontology is fixed with jacking block, institute
It states jacking block and is connected to the hollow channel equipped with apopore, several knife-edge leading ends of the step tool rear body are also equipped with
Apopore is connected to the hollow channel, and several apopores respectively spray to closest from step tool ontology described in its backwards
Blade.
The jacking block is connect with the nose threads of the step tool ontology as a preferred technical solution, the ladder
The hollow channel of the front end of cutter body is equipped with screw thread, and the jacking block is equipped with cannulated threaded post, and the jacking block passes through described
Cannulated threaded post is threadedly coupled with the hollow channel of the front end of the step tool ontology.
The hollow channel of the front end of the threaded step tool ontology is set as a preferred technical solution, as connection
Section, the linkage section are equipped with cooling hole, blade of the cooling hole towards step tool ontology front end；
The cooling hole is blocked when the cannulated threaded post stretches into the linkage section.
The invention is beneficial in that：
(1) present invention carries out cooling injection using the apopore of knife-edge leading end to blade, not only reduces the temperature of blade, and
And the discharge of iron filings discharge direction is also can help to, substantially increase the processing quality of stepped hole.
(2) structure substantially increases the service life of blade, reduces cutter maintenance cost.
(3) connection type of jacking block makes it is suitable for any blind hole or through-hole structure, and versatility is stronger.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of ladder aperture knife tool.
In figure：1- handle of a knifes, 2- step tools ontology, 3- apopores, 4- jacking blocks, 5- blades, 6- cooling holes.
Specific implementation mode
In order to facilitate the understanding of those skilled in the art, the present invention will be further described below with reference to the drawings.
As shown in Figure 1, a kind of ladder aperture knife tool, including step tool ontology 2, step tool ontology 2 are mounted on knife
On handle 1, step tool ontology 2 is internally provided with hollow channel, and the front end of step tool ontology 2 of the present invention is fixed with jacking block 4, jacking block
4, which are equipped with apopore 3, is connected to hollow channel, and 5 front end of several blades at 2 rear portion of step tool ontology is also equipped with the company of apopore 3
Logical hollow channel, several apopores 3 are respectively sprayed to backwards from its 2 immediate blade 5 of step tool ontology, and the present invention utilizes
The apopore 3 of 5 front end of blade carries out cooling injection to blade 5, not only reduces the temperature of blade 5, but also can help to iron filings
The discharge of discharge direction substantially increases the processing quality of stepped hole.
Jacking block 4 of the present invention is connect with the nose threads of step tool ontology 2, and the hollow of the front end of step tool ontology 2 is led to
Road is equipped with screw thread, and jacking block 4 is equipped with cannulated threaded post, and jacking block 4 passes through the front end of cannulated threaded post and step tool ontology 2
Hollow channel is threadedly coupled.The hollow channel for the front end for setting threaded step tool ontology 2 is set as linkage section by the present invention, even
It connects section and is equipped with cooling hole 6, blade 5 of the cooling hole 6 towards 2 front end of step tool ontology；Cannulated threaded post of the present invention stretches into
Cooling hole 6 is blocked when linkage section, cooling water can only be discharged by the apopore 3 on jacking block 4.
The Design Mechanism of above structure is derived from the process of stepped hole, due to roughing come out be a straight hole,
Step tool is just utilized when semifinishing, therefore, jacking block 4 can enter in stepped hole process in previous straight hole, the mistake
Journey does not influence processing early period of stepped hole, while ensure that processing quality, and adds if the hole of stepped hole bottommost also requires to have
When work requires, then jacking block 4 is dismantled, the processing of short time, which can't process blade 5, to be had an impact, and can equally ensure to process
Quality, and if the hole of stepped hole bottommost to processing no requirement (NR), can directly use original straight hole, such jacking block 4 again can
To continue to cool down subsequent blade 5 in straight hole.
The connection type of jacking block 4 of the present invention, make it is suitable for any blind hole either through-hole (including hole bottom also have it is non-must
Want straight hole) structure, versatility is stronger, and total is greatly improved the service life of blade 5, reduce cutter safeguard at
This.
It should be appreciated that the purposes of these embodiments is merely to illustrate the present invention and is not intended to limitation protection model of the invention
It encloses.In addition, it should also be understood that, after reading the technical contents of the present invention, those skilled in the art can be the present invention respectively
Kind change, modification and/or variation, all these equivalent forms equally fall within and are protected defined by the application the appended claims
Within the scope of shield.
