Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.But the purposes of these exemplary embodiments and purpose
Only being used for enumerating the present invention, not the real protection scope to the present invention constitutes any type of any restriction, more non-by this
Bright protection domain is confined to this.
Defining some nouns of locality in the present invention, in the case of not being specified to the contrary, the noun of locality used is such as
" upper and lower, left and right " refer to what the both-end main shaft that the present invention provides defined under normal usage, and with shown in accompanying drawing
Direction is consistent up and down." inside and outside " refers to inside and outside relative to the profile of each parts own.These nouns of locality be for the ease of
Understand and use, thus do not constitute limiting the scope of the invention.
In the present invention, when parts are referred to as " being fixed on " another parts, it can be directly at another zero
On part, or parts placed in the middle can also be there are.When parts are considered as " connection " another parts, and it is permissible
It is directly to another parts or may be simultaneously present parts placed in the middle.When parts are considered as " to arrange
In " another parts, it can be to be set directly on another parts or may be simultaneously present parts placed in the middle.
Suitably with reference to shown in Fig. 1, the both-end main shaft of the basic embodiment that the present invention provides includes clamping part 1, on clamping part 1
It is arranged with piston, also includes that revolving body, revolving body are set on clamping part 1 and are closed by piston, the revolving body both sides shaft shoulder divides
Not being provided with clutch shaft bearing 41 and the second bearing 42, both-end main shaft also includes main spindle box 5, arranges between main spindle box 5 and revolving body
There is hold-down ring 6.Hold-down ring 6 is wedge shape.
Clutch shaft bearing 41 and the second bearing 42 are high-speed bearing.This high-speed bearing axle both sides single-bearing, effectively reduces
The axial space of axle.Unclamping of this axle is directly entered inside main shaft by gas, and clamping is by the elongation of die springs, the most not only
Ease of assembly personnel install, and are also convenient for maintenance, are embodied everywhere design concept and the needs of hommization.This main shaft comes from outside
Seeing, mechanism is the most beautiful, and structure is the distinctest, on the premise of realizing function and technical specification, has accomplished attractive in appearanceization of product,
More can increase advantage for product.
Piston includes adjacent first piston 21 and the second piston 22.Revolving body includes the first revolving body 31 and the second revolution
Body 32, the first revolving body 31 and the second revolving body 32 are set on clamping part 1 and are arranged on first piston 21 and the second piston 22
Both sides, first piston 21 and the second piston 22 are closed.Owing to rotary body is made up of two parts, i.e. rotary body divides two parts,
Can conveniently dismantle, in order to this main shaft can do dynamic balancing easily.Any revolving body enclose rotate about the axis thereof time, due to phase
Centrifugal force is produced for the non-uniform mass of axis.This uneven centrifugal action can cause on rotor bearing and shakes
Dynamic, produce noise and accelerate bearing wear, so that having a strong impact on performance and the life-span of product.After doing dynamic balance treatment, can
Largely to improve the performance of axle
Clutch shaft bearing seat 71 it is provided with between main spindle box 5 and clutch shaft bearing 41.Arrange between main spindle box 5 and the second bearing 42
There is the second bearing block 72.
The selection GCr15 of clamping part 1 critical component material such as grade.The material that the clamping part 1 of this two ends clamping spindle uses is
GCr15, this material is a kind of the most frequently used high chromium bearing steel, has high quenching degree, can obtain height and uniform after heat treatment
Hardness, wearability is strong, and contact fatigue strength is high, has good dimensional stability and corrosion stability.
This main shaft uses high-speed bearing, it is possible to effectively improving rotating speed, clamping part 1 is connected with piston thread, piston driving
The movement of chuck.Release process, i.e. when there being ambient atmos to be entered by bearing block, is moved to the left clamping ring, at this moment clamping ring
On the left of inclined-plane and revolving body, inclined-plane is adjacent to, and the most other road ambient atmos enters in main shaft by main spindle box, promotes piston
To two side shiftings, the movement of piston driving chuck, it is achieved main shaft unclamps；The elongation by spring of clamping process, i.e. clamping ring, will
Clamping ring moves right, utilize on the left of piston and revolving body and on the right side of piston and revolving body between the deflection of die springs,
The two of a rotating body pistons are moved inward, it is achieved clamping process.
This novel bearing main shaft can not only be effectively improved the machining accuracy of product, decreases pollution and noise simultaneously.
Having volume little, rotating speed is high, the technical advantage that stability is high, it is possible to extensively apply the every field of machinery industry.This main shaft can
For on high-precision numerical control lathe, it is possible not only to improve the quality of product, and the life-span of cutter can also be extended, ensure lathe
The work of stability and high efficiency rate.
This novel bearing main shaft, uses high-speed bearing, not only effectively reduces the size of self and takes up an area space, and
Substantially increase running efficiency.Add can quickly start and stop, Quick-clamped, substantially increase its performance especially.Because
Use high-speed bearing, so frictional resistance is the least, improve its rotating speed further.Two ends clamping spindle uses high-speed bearing,
Cleannes are high, free from environmental pollution, and noise and vibration are little, more meet the developing direction in China's state-of-the-art technology field.
The sequencing of above example only for ease of describing, does not represent the quality of embodiment.
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit；Although
With reference to previous embodiment, the present invention is described in detail, it will be understood by those within the art that: it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent；
And these amendment or replace, do not make appropriate technical solution essence depart from various embodiments of the present invention technical scheme spirit and
Scope.
