Utility model content
Technical problem to be solved in the utility model is to propose a kind of barrel swivel part installation concentricity quickly to measure
Method and adjusting apparatus, overcome the shortcoming of dial gauge centering, are measured using digital display, by the rotary track of revolving meber, offset
Intuitively it is displayed on screen, can be easily adjusted according to offset, accuracy of measurement is high, and operating efficiency is high.
Technical solution of the present utility model is to provide a kind of barrel swivel body and installs concentricity method for fast measuring, bag
Include following steps：
First, arrange parameter
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 utility model also provides a kind of barrel swivel body and installs concentricity rapid measurement device, and it is characterized in that：
Including displacement transducer, fixture and display device are installed, above-mentioned installation fixture is arranged on rotary table top, for fixed tested work
Part；Upper displacement sensors are used to measure the relative shift of the outer wall with displacement transducer of measured workpiece；Above-mentioned display device
Including data acquisition unit, data storage cell, data processing unit and display unit, above-mentioned data acquisition unit gathers displacement
Sensing data, above-mentioned data storage cell storing measurement data, above-mentioned data processing unit is analyzed all measurement data and is counted
Calculate offset and eccentric direction；Above-mentioned display unit is received and shows the offset and eccentric direction data of part to be measured.
Preferably, more accurate and easy to operate in order to position, the utility model also includes Digiplex, above-mentioned wireless
Remote control is used for trigger data acquisition unit, and reduction causes to rotate and gather asynchronous and produce survey because installation site is unreasonable
The inaccurate problem of amount.
For the ease of adjusting the position of measured workpiece, above-mentioned fixture is fixed by screws on rotary table top.
Preferably, above-mentioned data processing unit uses arm processor STM32F103ZET6.
The beneficial effects of the utility model are：
1st, this patent uses the direct method of measurement, and measuring speed is relevant with the rotary speed of turntable, the faster measurement of rotary speed
Speed is faster.
2nd, display device compatibility is good, can receive with standard serial port output displacement transducer, such as differential transformer, lead
Electric plastic opaque sensor etc..
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is that the utility model measures display device acquisition process data flowchart.
Reference is in figure：1- turntables, 2- fixtures, 3- measured workpieces, 4- displacement transducers, 5- display devices, 6- numbers
According to line, 7- platforms, 8- bases, 9- Digiplexs.
Specific embodiment
The utility model is further described below in conjunction with drawings and the specific embodiments.
As shown in figure 1, the utility model adjusting apparatus, mainly include displacement transducer 4, install fixture 2 and display device 5
Deng.Turntable 1 is rotated with certain angular speed, drive measured workpiece 3 according to control direction clockwise or counterclockwise.Card is installed
Tool 2 is used to fixation and measured workpiece 3 is fixed on into rotary table top, it is ensured that its stabilization in rotary course.Displacement transducer 4 is real-time
The distance value of measurement measured workpiece 3 outer wall and the initial position of displacement transducer 4 in rotary course.The data acquisition of display device 5
Unit timing completes to sample to displacement transducer 4, by data storage value data storage cell, and measured value is sent to display
Display.The data processing unit of display device is analyzed and processes after the completion of one-shot measurement process to all data, counts
Eccentric value and offset maximum position are calculated, and is sent to display and shown.Adjusted according to positional information and eccentric value
The concentricity of whole 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
