1.1) angular speed of setting turntable, direction of rotation and sampled point quantity；
1.2) sampling time interval Δ t is calculated according to angular speed and sampling number；
2nd, sample
2.1) turntable is rotated, the initial position of collection displacement transducer, storing initial position data, and initial by what is gathered
Position data is sent to display unit；
2.2) turntable uniform rotation, since after the Δ t times in counting period initial position is sampled, gathers displacement transducer
Data, data storage；So repeat, until collection is finished；
2.3) after turntable rotates a circle, sampled point is reached, stops sampling；
3rd, data processing
3.1) processing data, obtains the offset and eccentric direction of measured workpiece；
3.2) real-time measurement point, offset and eccentric direction are shown；
4th, adjustment measurement
Display result according to display unit adjusts the position of measured workpiece, repeat step two and step 3, until tested
Untill concentricity of workpiece meets requirement.
The present invention also provides a kind of barrel swivel body and installs concentricity rapid measurement device, and it is characterized in that：Including

Specific embodiment
Below in conjunction with drawings and the specific embodiments, the present invention will be further described.
As shown in figure 1, adjusting apparatus of the present invention, mainly include displacement transducer 4, install fixture 2 and display device 5 etc..
Turntable 1 is rotated with certain angular speed, drive measured workpiece 3 according to control direction clockwise or counterclockwise.Fixture 2 is installed
It is used to fixation and measured workpiece 3 is fixed on rotary table top, it is ensured that its stabilization in rotary course.Displacement transducer 4 is surveyed in real time
The distance value of amount measured workpiece 3 outer wall and the initial position of displacement transducer 4 in rotary course.The data acquisition list of display device 5
First timing completes to sample to displacement transducer 4, by data storage value data storage cell, and measured value is sent to display shows
Show.The data processing unit of display device is analyzed and processes after the completion of one-shot measurement process to all data, calculates
Go out eccentric value and offset maximum position, and be sent to display to be shown.According to positional information and eccentric value adjustment
The concentricity of workpiece and turntable.
With reference to Fig. 1 and Fig. 2, by the axial line of displacement transducer 4 perpendicular to turntable axial line, the outer wall of measured workpiece and position
Displacement sensor 4 contacts reliability, and the adjustment show value of displacement transducer 4 is near the median of full scale.Turntable 1 is set with fixed angles
Speed is rotated, and rotational speed values and direction of rotation are input into display device 5 by the man-machine interface of display device 5, is shown
The data processing unit of showing device 5 calculates sampling time interval Δ t.In revolving part gauge head initial position mark-on will, lathe starts rotation
