Detailed description of the invention
Below, by reference to the accompanying drawings and detailed description of the invention, the utility model is described further:
As shown in Figure 1, for a kind of Novel electric spindle device of the present utility model, comprise with chamber main shaft 1, adopt the mode of interference fit to be sleeved on ladder cover 2 on main shaft 1, adopt the mode of interference fit to be sleeved on rotor 3 on ladder cover 2, described ladder cover 2 is formed for the limiting section 21 spacing to rotor 3, the inner diameter values that described ladder overlaps 2 one end is greater than the inner diameter values of the other end, the cooperation of the described ladder cover inwall of 2 and the outer wall of main shaft 1 is formed with cavity 5, and the sidewall of described ladder cover 2 is formed with the liquid injection port 22 be connected with this cavity 5.Cavity 5 can be formed in the middle position of ladder cover 2, and in Fig. 1, the length value of L1 equals the length value of L2.When actual fabrication, can be that the inner diameter values that ladder overlaps 2 right-hand members is greater than the inner diameter values that ladder overlaps 2 left ends, namely in Fig. 1, the diameter of D1 be greater than the diameter of D2.
Ladder cover 2 is sleeved on main shaft 1 by adopting the mode of interference fit by the present embodiment, then the mode of interference fit is adopted to be sleeved on by rotor 3 on ladder cover 2, ladder cover 2 is formed for the limiting section 21 spacing to rotor 3, significantly can reduce the amount of unbalance of main shaft 1, the phenomenon of vibration is there is when can effectively prevent main shaft 1 from rotating, and the inner diameter values of ladder cover 2 increases from left to right gradually, the cooperation of the ladder cover inwall of 2 and the outer wall of main shaft 1 is formed with cavity 5, the sidewall of ladder cover 2 is formed with the liquid injection port 22 be connected with this cavity 5, when needing ladder cover 2 to dismantle from main shaft 1, injection liquid press liquid liquid injection port 22, hydraulic fluid flows in cavity 5, under the effect of hydraulic fluid, main shaft 1 is dismantled from ladder cover 2 very easily.
Preferably, described ladder cover 2 is fitted with multiple adjustment screw 4, described adjustment screw 4 is along the center line circumference arrangement of ladder cover 2.By these adjustment screw 4, the degree of balance of tunable integer body device.Specifically when operating, by arranging number and the distributing position of adjustment screw 4, or the screw-in depth of adjustment screw 4 is set, and then the degree of balance of adjustment single unit system.
Preferably, the inner homogeneous of described main shaft 1 is placed with multiple water channel, and described water channel extends along the axial direction of main shaft 1, and being connected in turn end to end of each water channel is through, form a bending water channel, the two ends of this bending water channel form water inlet and delivery port in the front end of main shaft 1.By injecting cooling fluid in water inlet, cooling fluid flows through the through water channel that is connected in turn end to end, finally flows out from water outlet, is also taken out of together by heat simultaneously, thus the phenomenon effectively preventing from main shaft 1 from heat operationally occurring cannot shedding in time, the service life of significant prolongation main shaft 1.
Preferably, the circular in cross-section of described water channel, can facilitate the circulation of water liquid.
Preferably, the quantity of described liquid injection port 22 is multiple, along the center line circumference arrangement of ladder cover 2.Liquid injection port 22, when arranging number, needs the degree of balance having taken into full account main shaft 1, its number preferably even number.
Liquid injection port 22 li can be connected with the hydraulic oil in the external world or hydraulic pressure aqueous phase, by the injection of these hydraulic oil or hydraulic pressure water, facilitates main shaft 1 from the dismantlement work ladder cover 2.
Ladder cover 2 is first sleeved on main shaft 1 by the utility model, then the mode of interference fit is adopted to be sleeved on by rotor 3 on ladder cover 2, limiting section 21 can carry out effectively spacing to rotor 3, the rotation of rotor 3 can drive ladder to overlap the rotation of 2, and then drive the rotary work of main shaft 1, significantly reduce the amount of unbalance of main shaft 1, the phenomenon of vibration occurs when can effectively prevent main shaft 1 from rotating.When ladder cover 2 is dismantled from main shaft 1 by needs, injection liquid press liquid liquid injection port 22, hydraulic fluid flows in cavity 5, under the effect of hydraulic fluid, main shaft 1 is dismantled very easily from ladder cover 2.Main shaft 1 after a period of operation, needs to carry out cooling work to main shaft 1, can pass into cooling fluid, taken out of by the heat of main shaft 1 inside from water outlet from water inlet, extends the service life of main shaft 1.
Symmetrical configuration of the present utility model, uniform quality, main shaft 1 dynamic balancing is easy to ensure; The main shaft 1 of this device and ladder cover 2 adopt interference fit joint, ladder cover 2 and rotor 3 adopt interference fit joint, make the location of this device very reliable, the rigidity of main shaft 1 can be improved, and bending and torsion stress can not be produced on main shaft 1, on main shaft 1 running accuracy without impact, be also easy to the axiality ensureing rotor 3 and main shaft 1.The utility model can adopt hot charge practice to assemble, and creosoting process is dismantled, and mounting or dismounting are convenient, harmless to main shaft 1.
For a person skilled in the art, according to technical scheme described above and design, other various corresponding change and distortion can be made, and all these change and distortion all should belong within the protection domain of the utility model claim.
