Diameter Straightness Measuring Instrument

Diameter Straightness Measuring Instrument

Straightness Measuring Instrument

The equipment adopts the principle of measuring the diameter and position of the photoelectric probe for measurement. The measuring instrument uses 2-way photoelectric probes distributed at 90 degrees to measure the diameter and position of the object at the same time and uses the position data of the 2-way probes to calculate the measurement point. The actual deviation in the coordinate system. When measuring straightness, the measuring instrument scans once along the axis of the measured object.

The equipment is mainly used for the diameter and straightness detection of metal rods, pipes, ceramic pipes and other products

Basic Principal

Straightness Measuring Instrument

 

Data calculation

The system fits a straight line based on the X-axis position values collected at position 1 and position 3, and the deviation between the measured value at position 2 and the straight line is the straightness error of position 2 in the X-axis direction. Similarly, the straightness error of position 2 in the Y-axis direction can be obtained. Assuming that the straightness error of the X-axis is δ1 and the straightness error of the Y-axis is δ2, the actual error δ of the bar straightness can be calculated.

 

Brief description of functions

Simultaneous measurement of outer diameter and straightness

The system can set the calculation and display of various errors such as head error, tail error, overall error, and error per meter according to the quality control requirements of the measured object

Display content

Computer display in the control cabinet section: real-time diameter measurement value, ellipticity value;

2-4m pipe: the straightness data within 500mm at both ends and the straightness data of the whole pipe;

1-1.5m pipe shows the whole straightness data.

Software function

Product parameter setting: parameters such as product specification, bar nominal diameter, and straightness tolerance can be set
Alarm setting: You can set the threshold value of the alarm, sound and light alarm when the measured value is out of tolerance; set the alarm for straightness within 500mm at both ends of the 2-4m pipe, set the alarm for the straightness of the entire steel pipe; set the alarm for the outer diameter exceeding 200mm on both sides

Correction function: when the error is too large, the calibration can restore the accuracy after putting in the standard straight rod

Storage function: keep a complete measurement record for each steel

Alarm function

The measured data exceeds the standard value, sound and light alarm

Communication Interface

TCP/IP protocol, network cable transmission, diameter measuring instrument to industrial computer
