The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term " and or " used herein includes one or more phases
Any and all combinations of the listed item of pass.
One, design principle
(1) media supply that existing electro spindle pushes generally uses air pressure to drive, and referring to Fig. 1, cylinder is forged a knife cylinder structure packet
It includes and is equipped with one 1.1.2 of cylinder block, cylinder block below cylinder top cover 1.1.1, the cylinder top cover 1.1.1 with gas source connector
Two 1.1.3, three 1.1.4 of cylinder block, four 1.1.5 of cylinder block, one 1.1.6 of cylinder piston, two 1.1.7 of cylinder piston, cylinder
Three 1.1.8 of piston, four 1.1.9 of cylinder piston.There is rod assembly 1.2.1 to be mounted below cylinder knife striking cylinder.The cylinder is living
A 1.1.6, two 1.1.7 of cylinder piston, three 1.1.8 of cylinder piston are filled in, is equipped with venting channels inside four 1.1.9 of cylinder piston.
When cylinder knife striking cylinder starts operation, compressed gas is filled with the gas source connector being equipped with above cylinder top cover 1.1.1, into cylinder top cover
1.1.1 the first layer cavity constituted with one 1.1.2 of cylinder block forces cylinder while compressed gas is full of the first cavity
One 1.1.6 of piston is moved down.While one 1.1.6 of cylinder piston is moved down, compressed gas is also by cylinder piston one
1.1.6 venting channels enter the second layer cavity that one 1.1.2 of cylinder block and two 1.1.3 of cylinder block are constituted, full
One 1.1.6 of compressed gas and cylinder piston collective effect under force two 1.1.7 of cylinder piston to move down, similarly cylinder is living
It fills in three 1.1.8 to move down under the collective effect of full two 1.1.7 of compressed gas and cylinder piston, similarly cylinder piston four
1.1.9 it is moved down under the collective effect of full three 1.1.8 of compressed gas and cylinder piston, subsequent cylinder piston four
1.1.9 enough thrust is provided for rod assembly 1.2.1, the movement so that rod assembly 1.2.1 completion is forged a knife.Air pressure is to utilize pressure
Contracting gas sacrifices pressure with big air pressure to exchange cylinder stroke for, and gas needs to obtain high compression ratio, then needs more

The gas source connector of 2.2 top of lid is filled with compressed air, and full compressed air is equipped with by cylinder pressure top cover 2.2 and molten steel set 2.3
Reset gas passage enter and quickly fill with cylinder pressure top cover 2.2 and seal cavity (air storing cavity) that molten steel set 2.3 is constituted.?
Under the collective effect of pull-rod nut 2.6 and compressed gas, piston 2.5 up moves to original position.Original hydraulic oil in seal chamber
Also the oil inlet passage discharge forged a knife being equipped with therewith from cylinder pressure top cover.Forging a knife for oil cylinder knife striking cylinder is completed with homing action.
(2) system is cooling
When electro spindle installs central water outlet Special scalpel handle and starts operation, electro spindle central water outlet function starts to start,
Cooling water with high flow rate is passed through the water source connector of 2.1 top of central water outlet component, and by inside central water outlet component 2.1
The water passage being equipped with enters high-speed rotating rod assembly 2.9, and 2.1 inside of central water outlet component exists with rod assembly 2.9
The position being association of activity and inertia, the cooling water that this position leaks, the overflow water swivel being equipped with from center outlet component 2.1 are expelled to
Outside main shaft.Subsequent cooling water is passed through sliding core assembly 2.8 from the water passage that rod assembly 2.9 is equipped with, and flows into slide cores group
The cooling water of part 2.8 subsequently enters the knife handle component being connected with sliding core assembly 2.8, and last cooling water is sprayed from knife handle component
Out, it is ejected into workpiece surface.Cutter post-processing surface is cooled down, cutting heat is taken away, takes away work piece surface generation
Dust particle reaches and reduces cutter loss, extends the effect in main shaft service life.Remaining dust particle is avoided simultaneously destroys workpiece
Surface influences the surface accuracy of machined surface.

Five, technological innovation advantage
(1) it can provide bigger power of forging a knife.The present invention uses oil cylinder knife striking cylinder, general compared to existing electro spindle on the market
The cylinder of use, which is forged a knife, can provide bigger power of forging a knife.Existing cylinder knife striking cylinder is using compressed gas, with big air pressure
Power sacrifices pressure to exchange cylinder stroke for, and gas needs to obtain high compression ratio, then needs more gases, action stability
Difference, easily leakage, operating pressure are low, therefore the thrust that single cylinder knife striking cylinder can be generated is insufficient, and cylinder knife striking cylinder generally requires
Multilayer cylinder body could provide the enough power of forging a knife, so that structure is complicated for cylinder knife striking cylinder, processing cost is higher.Or it needs to use
Bigger cylinder block can be only achieved the enough power of forging a knife, and excessive cylinder block volume can make electro spindle that can not be mounted on
On board.And the oil cylinder knife striking cylinder that the present invention uses is the thrust for exchanging oil cylinder for big hydraulic fluid flow rate, can be reached very
High operating pressure, reaction speed is faster compared to air pressure.The power of forging a knife that oil cylinder knife striking cylinder provides is related with the flow velocity of hydraulic oil, with
The volume of hydraulic oil is unrelated, therefore oil cylinder forges a knife and only needs small oil cylinder volume, so that it may provide bigger power of forging a knife.
(2) central water outlet function is had.Due to the central water outlet technology of electro spindle, part processing precision requires high, assembly
Difficulty is big, and electro spindle on the market is not equipped with central water outlet function substantially at present.Present invention offer has the function of central water outlet,
Its specific embodiment is as described above.Using central water outlet, a large amount of cutting heat of work piece surface can be taken away, and takes away and adds
The dust particle that workpiece surface generates reaches and reduces cutter loss, extends the effect in main shaft service life.Remaining powder is avoided simultaneously
Dirt particle damage workpiece surface, influences the surface accuracy of machined surface.
(3) the oil cylinder knife striking cylinder of compatible central water outlet component.Compared to the electro spindle forged a knife on the market equipped with oil cylinder at present,
The compatible central water outlet component of the oil cylinder knife striking cylinder that the present invention uses, solve central water outlet function and oil cylinder forge a knife function can not
Coexistent problem.
Oil cylinder is forged a knife technology and central water outlet technical application to electro spindle field by the present invention.The good solution of this electro spindle
Existing electro spindle is forged a knife using cylinder, the dust that cutting heat and workpiece generate when power of forging a knife is insufficient or cylinder volume is excessive and processing
