In the present embodiment, described two ends clamping spindle also includes proximity switch, described main spindle box is offered porose,
Described proximity switch is installed in described hole.
Two ends of the present utility model clamping spindle, uses the design of overall model structure, effectively reduces master
The axial space of axle；Unclamping of this axle, clamping device is connected with valve by cylinder, the most not only facilitates group
Dress personnel install, and are also convenient for maintenance, are embodied everywhere design concept and the needs of hommization.This main shaft from
From the point of view of outside, mechanism is the most beautiful, and structure is the distinctest, on the premise of realizing function and technical specification,
Accomplish attractive in appearanceization of product, more can increase advantage for product.
And the material that two ends of the present utility model clamping spindle uses is GCr15, this material is that one is the most normal
High chromium bearing steel, there is high quenching degree, height can be obtained after heat treatment and uniform hardness.Wearability
By force, contact fatigue strength is high, has good dimensional stability and corrosion stability.
Two ends of the present utility model clamping spindle is made up of two parts due to rotary body, i.e. rotary body divides two parts,
Can conveniently dismantle, in order to this axle can do dynamic balancing easily.Any revolving body rotates about the axis thereof enclosing
Time, centrifugal force is produced due to the non-uniform mass relative to axis.This uneven centrifugal action
Rotor bearing can cause vibration, produce noise and accelerate bearing wear, so that having a strong impact on the property of product
Energy and life-span.After doing dynamic balance treatment, can largely improve the performance of axle.
Further, described two ends clamping spindle uses proximity switch oriented approach, realizes orientation trouble.
Breach in proximity switch detection solid of revolution, passes to spindle motor signal by proximity switch, it is achieved to master
Axle orients.
Two ends of the present utility model clamping spindle uses high-speed bearing, it is possible to effectively improve rotating speed, (left and right)
Chuck uses with (left and right) piston threadeds, by the movement of piston driving chuck, it is achieved main shaft unclamps,
Clamping process.I.e. air enters a rotating body through valve, is displaced outwardly by the two of a rotating body pistons,
Release process completes.Utilize the deflection of die springs simultaneously, the two of a rotating body pistons moved inward,
Realize clamping process.
This novel bearing main shaft can not only be effectively improved the machining accuracy of product, decrease simultaneously pollution and
Noise.Having volume little, rotating speed is high, the technical advantage that stability is high, it is possible to extensively apply machinery industry
Every field.This main shaft may be used on high-precision numerical control lathe, is possible not only to improve the quality of product, and
And life-span of cutter can also be extended, ensure the work of lathe stability and high efficiency rate.
Therefore this two ends clamping spindle is primarily to improve the machining accuracy of machine and rotating speed, reduce vibration and
Noise, in place of replacing some shortcomings and deficiencies of conventional air-floating main shaft, the production efficiency of further hoisting machine
With crudy.
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 the technical solution of the utility model, rather than right
It limits；Although this utility model being described in detail with reference to previous embodiment, this area common
