Specific embodiment
The principle and features of the present invention will be described below with reference to the accompanying drawings, and the given examples are served only to explain the present invention, and
It is non-to be used to limit the scope of the invention.
As shown in Figure 1-3, a kind of external-change-internal cold type mechanism for grinding tool, including grinding tool 1 and water inlet 2,
The water inlet 2 is in the top of the grinding tool 1 for pouring into coolant liquid into the grinding tool 1.The grinding work
It is equipped in tool 1 as the rotation of the grinding tool 1 forms water scooping machine of the vortex to suck coolant liquid from the water inlet 2
Structure.The grinding tool 1 is cylindrical drill, cup/saucer wheel, annular mill or other by cross grinding/cutting rotation mill
Tool or cutter.Come when below using grinding tool as cylindrical drill for example:
As shown in figure 4, the water-absorption mechanism includes vortex board 3 and blade 4.The vortex board 3 is fixed on the grinding work
In the tool 1 i.e. sleeve of cylindrical drill and at the position of corresponding 2 lower section of the water inlet.Connection structure is equipped at the top of the vortex board 3
8, the connection structure 8 connects equipment for grinding, that is, drilling machine main shaft after passing through the water inlet 2 axially upward, in the drive of drilling machine
The rotation of the sleeve 1 of dynamic lower realization cylindrical drill.The blade 4 is equipped with several, is distributed on the vortex board 3 and with institute
The rotation for stating the sleeve 1 of cylindrical drill forms vortex.It is preferred: 4 spiral of the blade setting, and the spiral shell of all blades 4
It is identical to revolve direction, the setting of 4 spiral of blade can be enhanced the eddy current effect occurred after rotation, and then improve coolant liquid from water inlet
The adsorption capacity of mouth sucking.During material is drawn in the rotation processing of the sleeve 1 of cylindrical drill, vortex board 3 and blade 4 can be rotated synchronously,
Since 4 relative level of blade is screw arrangement by the oblique design of preset angle, drive air in water inlet 2 after rotation
Lower section forms the vortex to coolant liquid tool impetus, so that boosting coolant liquid can pass through at water inlet 2 because high speed is revolved
Turn the airflow barrier formed, coolant liquid is sucked in the sleeve 1 of cylindrical drill, even if realize 1 high-speed rotation of sleeve of cylindrical drill
Coolant liquid liquid can smoothly enter through water inlet 2 and cool down to drilling face, guarantee to process in 1 high-speed rotation of sleeve of cylindrical drill
When can also accomplish whole cooling.In addition, the water-absorption mechanism that the present invention is formed by above-mentioned vortex board 3 and blade 4, can will intake
2 design of mouth circularizes 360 degree of accessible forms, and the effluent pipe mouth of coolant liquid supply can penetrate into grinding work through water inlet 2
The inner cavity of matrix is entered directly into after tool 1, to abolish the airflow barrier at water inlet 2.In the prior art, by being ground
Get through the modes such as hole in tool base, coolant liquid pour after matrix surface carried out by the inner cavity that through-hole enters matrix it is outer cold,
No matter upper surface or the excircle of matrix is arranged in through-hole, and the effluent pipe mouth of coolant liquid supply cannot enter matrix
Inner cavity, the reason is that grinding tool rotation will rotate together with outlet pipe, this is interior if effluent pipe mouth reaches inner cavity from through-hole
The concept of air-cooled structure.And the present invention is that the cooling effect of interior cold mode is realized by " outer cold " structure.
Following three kinds of modes are distributed on the vortex board 3 in the blade 4: it is outer to be distributed in 3 top of vortex board
Monday circle is distributed in Monday circle outside 3 bottom of vortex board, is distributed in 3 top peripheral one of the vortex board circle and bottom periphery
One circle, wherein it is most strong in the vortex that 3 top peripheral of vortex board and bottom periphery are distributed the formation of blade 4 simultaneously, to coolant liquid
Adsorption capacity it is also maximum.The distribution mode of corresponding above-mentioned three kinds of blades 4, using with the one-to-one fixing screws 6 of blade 4,
Vortex board 3 and blade 4, which are fixed in the sleeve 1 of cylindrical drill corresponding position, also following three kinds: the first, by fixing screws
6 sequentially pass through from top to bottom the side wall that 2 periphery of water inlet is corresponded at the top of the sleeve 1 of the cylindrical drill, the corresponding blade 4 with
And the vortex board 3；Second, fixing screws 6 are sequentially passed through from top to bottom described in being corresponded at the top of the sleeve 1 of the cylindrical drill
Side wall, the vortex board 3 and the corresponding blade 4 of 2 periphery of water inlet；The third, by fixing screws 6 from top to bottom according to
The secondary side wall that 2 periphery of water inlet is corresponded at the top of the sleeve 1 of the cylindrical drill, it is corresponding in the vortex board 3 push up
Blade 4, the vortex board 3 and the corresponding blade 4 in 3 bottom of vortex board in portion.
The neighboring of the vortex board 3 extends outwardly at the position close to 1 inner wall of sleeve of the cylindrical drill, in turn
It is formed between the vortex board 3 and 1 inner wall of sleeve of the cylindrical drill in sleeve 1 of the limitation coolant liquid along the cylindrical drill
The water conservancy diversion gap 7 that wall flows downward.The vortex board 3 of grinding tool inner cavity is entered after in the sleeve 1 of coolant liquid sucking cylindrical drill
On, by multiple actions such as the promotion of blade 3 and centrifugal force, will cause on vortex board 3 coolant liquid towards the periphery of vortex board 3 i.e.
The inner wall of grinding tool is mobile, is not easy to throw away outside the sleeve 1 of cylindrical drill through water inlet 2 upward.Under the action of water conservancy diversion gap 7,
The coolant liquid for being moved to the inner wall of grinding tool flows downward along inner wall, finally in the pressure of coolant liquid, gravity and centrifugal force
Under the action of the drilling face of 1 bottom of sleeve through cylindrical drill throw away, play the cooling effect of interior cold mode, and increase coolant liquid
With the contact area of the sleeve 1 of cylindrical drill, the utilization rate of coolant liquid is improved.
The vortex board 3 is coaxially disposed with the water inlet 2, and the radial dimension of the vortex board 3 be greater than it is described into
The radial dimension at the mouth of a river 2, so correspond at the top of the sleeve of the cylindrical drill 12 periphery of water inlet side wall and the whirlpool
The storage area 5 of interim storage coolant liquid is formed between flowing plate 3.Storage area 5 can be first stored temporarily in by the coolant liquid that blade 4 sucks
Interior, storage area 5 provides the cavity temporarily stored for coolant liquid, the coolant liquid avoided enter into because cannot store and with set
Expect that the rotation of the sleeve 1 bored is flow backwards away from water inlet 2 again.
By the way that grinding tool 1 is designed as cup emery wheel, saucer wheel, annular mill, above-mentioned external-change-internal cold type mechanism is same
Sample can be applied in cup emery wheel, saucer wheel, annular mill or other by cross grinding/cutting rotating grinding tool or cutter
On, and also can guarantee that coolant liquid also can when the grinding tools such as cup emery wheel, saucer wheel, annular mill or cutter are in high-speed rotation
Smoothly enter through water inlet and grinding surface is cooled down, realizes in grinding tools or knives such as cup emery wheel, saucer wheel, annular mills
It can also accomplish whole cooling when tool high-speed rotation processing.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and
Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
