Description
Technical field
The present invention relates to a kind of lathe precise testing device, a kind of dress of machine tool chief axis vibration displacement measurement is related generally to
Put, more particularly, to a kind of for analyzing device of the vibration noise on the measurement influence of machine tool chief axis vibration displacement.
Background technology
During machine tooling machine components, abrasion and longevity of the vibration that main shaft is produced to processing precision of products and cutter
Life has considerable influence.The machine components of machining high-precision, rotating accuracy, circularity precision to machine tool chief axis, cylindricity precision
Deng there is requirement very high.Spindle rotation error, deviation from circular from, deviation from cylindrical form etc. are to weigh machining center and machine tool accuracy
Important indicator, generally test assessment can be carried out to it using two dimensional method, line-of-sight course etc..By measurement, it will be appreciated that lathe master
The working condition of axle, analytical error Producing reason；On the other hand, very big vibration can be produced during main axis, is accurately
Collect the vibration displacement signal of main shaft, it is necessary to take certain vibration isolation measure to ensure that it is authentic and valid that displacement transducer is collected
Data, and then convenient treatment and analyze data.Existing main measurement and vibration isolating method are as follows：
Two-point method：Accurate measurement to spindle vibration displacement is, it is necessary at least two sensors are mutually perpendicular in main axis cross section
Both direction gathered data simultaneously, but the error separate that simple vertical two-point method cannot install sensor is out, from
And influence the accuracy of measurement result；
Line-of-sight course：Three sensors gathered data simultaneously is needed, three sensors will be located in same main shaft section, and are intersected at
The geometric center of main shaft.Line-of-sight course requirement test device need to have machining accuracy higher, while the clamping, debugging to sensor will
Ask higher.But line-of-sight course can produce serious harmonics restraint, so as to influence the accuracy of experiment；
The advantage of four-point method or other multipoint methods is to carry out error separate, energy using the sensor gathered data of four or more
Enough reduce harmonics restraint.But it is more complicated that this also makes that data processing becomes, while the installation that brings of multiple sensor is to the heart, accurate
Angle arrangement, the difference problem between sensor performance can equally reduce the precision of error separate result；
Active Vibration Isolation：It is in itself the equipment of vibration source for machine, in order to reduce their influences to miscellaneous equipment around, will
They and ground（Or supporting）Keep apart.This to be isolated vibration source, the vibration of vibration source by passing again after vibration damping
Vibration isolation be referred to as active vibration isolation；
Passive vibration isolation technology：Equipment for needing vibration isolation, in order to reduce influence of the surrounding vibration source to it, it is necessary to by it with it is whole
Ground（Or supporting）Keep apart.It is this to be isolated equipment, flexible member, damping element are added between vibration source and system
Even inertance element etc., prevents vibration source to be around transmitted to the vibration isolation referred to as passive vibration isolation of equipment.
To sum up, when measuring spindle vibration displacement, the vibration of sensor installation accuracy and isolation vibration source is most important.
However, existing spindle rotation accuracy measurement experiment device, such as " for the mixing of spindle rotation accuracy measurement experiment
Multi-method test device "（CN105033759A）, although radial displacement adopts when can be used for various experiment purpose main shaft gyrations
Collection experiment, and the positioning precision of sensor is ensure that, but not in view of bed body during main axis because of power source and transmission
The influence that vibration caused by unstable is tested spindle rotation accuracy, therefore cannot contrast and whether vibrate to machine tool chief axis revolution essence
Spend the influence of test.Although, existing vibration-isolating platform, such as " passive vibration isolation platform "（CN204083050U）Also the work of vibration isolation can be played
With, but cannot be used directly for the test of Rotary Precision of Spindle of Machine Tools：One because its structure is installed, adjusts inconvenience, it is impossible to adapted to
Precision measurement；Two because existing vibration-isolating platform can not ensure test sensing station it is constant under conditions of to vibration carry out every
From.It is the vibration displacement of accurate measurement main shaft, not only ensures the installation accuracy of sensor, more isolates the vibration of vibration source.
Research shows, during machine tooling part, main shaft vibration displacement produced when working is influence processing
The major disturbances source of quality and precision, therefore find a kind of reliability and easily clamp of sensor vibration-isolating platform, accurately measurement
The actual vibration displacement for going out main shaft has important practical significance.It is measurement spindle vibration that the Main Function of apparatus of the present invention is exactly
Displacement provides good vibration isolation experimental situation.
