It is additionally provided with some coolant spray orifices, the coolant spray orifice is distributed in the periphery of annular bar seam, and all coolant spray orifices are to guarantor
The second cushion chamber is come together in after extending inside protection unit, second cushion chamber is connected with outside liquid supply equipment；The coolant
The oblique main shaft of injection direction of spray orifice and annular bar seam.
So, in the vertical machining centre course of work, gases at high pressure are squeezed into cushion chamber by outside air feed equipment, and gas exists
Main shaft is sprayed to by annular bar seam after being buffered in cushion chamber, cushion chamber can effectively ensure that the air-flow in annular bar seam is steady
Uniformly, so as to form the air curtain of a back taper around main shaft, prevent chip from entering main shaft；At the same time, outside feed flow is set
It is standby that outside cooling medium is squeezed into the second cushion chamber, and cause cooling medium to spray to main shaft by coolant spray orifice, main shaft is carried out
Cooling and lubricating, the heat affecting of main shaft is reduced, extend the service life of main shaft, be effectively protected main shaft.
Further, the width of the annular bar seam gradually increases from the bottom to top.
Further, the diameter of the coolant spray orifice gradually increases from the bottom to top.
Further, the axis of bearing of trend of the annular bar seam and the angle of horizontal plane are 30 °~45 °.
Further, the axis of the bearing of trend of the coolant spray orifice and the angle of horizontal plane are 30 °~45 °.
The beneficial effects of the utility model：By to around main shaft formed taper air curtain and combine spray cooling liquid, effectively
Prevent chip and dust enters damage of the main shaft to main shaft, and cooling and lubricating, simple in construction, user can be carried out to main shaft
Just, the service life of main shaft is extended, protection main shaft effect is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the utility model upward view.
Embodiment
The utility model is described in detail below with reference to accompanying drawing：
As shown in Figure 1-2：
A kind of vertical machining centre main shaft protection device, including the protection device 1 being set on motor stator part, it is described
The bottom end face of protection device 1 is provided with annular bar seam 2, and the annular bar seam 2 extends to the inside of protection device 1 and with being arranged on
Cushion chamber 3 inside protection device 1 is connected, and the cushion chamber 3 is connected with outside air feed equipment；At the bottom of the protection device 1
Some coolant spray orifices 4 are additionally provided with end surface, the coolant spray orifice 4 is distributed in the periphery of annular bar seam 2, and all coolings
Liquid spray orifice 4 connects to the second cushion chamber 5, second cushion chamber 5 is come together in after extending inside protection device 1 with outside liquid supply equipment
Connect；The oblique main shaft of injection direction of coolant spray orifice 4 and the annular bar seam 2.
So, in the vertical machining centre course of work, gases at high pressure are squeezed into cushion chamber 3 by outside air feed equipment, buffering
The space of chamber 3 is larger, and row buffering can be entered to gas and homogenizes the gas pressure of each several part, makes air-flow more steady, gas
Body stitches 2 by annular bar after being buffered in cushion chamber 3 and sprays to main shaft, and cushion chamber 3 can effectively ensure in annular bar seam 2
Air-flow even, so as to form the air curtain of a back taper around main shaft, prevent chip from entering main shaft；At the same time, outside
Outside cooling medium is squeezed into the second cushion chamber 5 by portion's liquid supply equipment, and causes cooling medium to spray to main shaft by coolant spray orifice 4,
Cooling and lubricating is carried out to main shaft, the heat affecting of main shaft is reduced, extends the service life of main shaft, be effectively protected main shaft.
The width of the annular bar seam 2 gradually increases from the bottom to top.Tapered spout can be right under certain air pressure
Gas is accelerated, and so so that the gas sprayed in annular bar seam 2 possesses certain speed, is easy to blow down the broken of splashing at a high speed
Bits, improve the protecting effect of air curtain.
The diameter of the coolant spray orifice 4 gradually increases from the bottom to top.Tapered spray orifice form is advantageous to improve injection
Speed and pressure, it is easy in time rush the chip being bonded on cutter and removes, prevent influence of the chip to machining accuracy.
The axis of bearing of trend and the angle of horizontal plane of the annular bar seam 2 are 30 °~45 °.
The axis of bearing of trend and the angle of horizontal plane of the coolant spray orifice 4 are 30 °~45 °.
So, angle too small will increase the flow of air-flow, and speed reduces, it is impossible to effectively form stable air curtain and
Emitted dose, angle is excessive, increases the volume of protection device and blows down scope and diminish, protecting effect is bad, it is therefore desirable to according to adding
Work central principal axis length and the specification of Common Use Tools select rational spray angle.
The beneficial effects of the utility model：By to around main shaft formed taper air curtain and combine spray cooling liquid, effectively
Prevent chip and dust enters damage of the main shaft to main shaft, and cooling and lubricating, simple in construction, user can be carried out to main shaft
Just, the service life of main shaft is extended, protection main shaft effect is good.
Above example is only to illustrate the technical solution of the utility model and unrestricted, although with reference to preferred embodiment pair
The utility model is described in detail, it will be understood by those within the art that, can be to technology of the present utility model
Scheme is modified or equivalent substitution, and without departing from the objective and scope of technical solutions of the utility model, it all should cover
Among right of the present utility model.
