Calibration device for construction quality detector group

1、 Instrument Introduction:

Calibration device for construction quality detector groupyesOur company strictly follows the "JF1110-2003 Calibration Specification for Construction Quality Detector Group" for research and development and productionA specialized calibration device used to detect the indication errors of vertical inspection rulers, inner and outer right angle inspection rulers, and wedge-shaped plug gauges in the construction quality detector group. The device'sThe vertical body is composed of stable granite, high-precision micrometer head, and adjustable horizontal granite base.

2、 Instrument composition:

This calibration devicefromXR-2000C typeVerticality detection ruler calibration device andThe XR-300Z inner and outer right angle measuring ruler calibration device consists of two instruments.XR-2000C typeVerticality detection ruler calibration devicefor detectionVertical inspection rulerIndication error,XR-300Z Type Internal and External Right Angle Ruler Calibration Device for TestingThe indication error of the inner and outer right angle measuring ruler and wedge-shaped plug gauge.

3、 Working principle:

Calibration device for construction quality detector groupUsing the comparative method for measurement, the standard angle β 1 (sin β 1=L1/R) is composed of the ratio of the distance traveled by the digital micrometer head to the distance L1 between the axis of the rotary shaft and the axis of the guide shaft. The indication error of the verticality detection ruler angle β 2 (sin β 2=L2/R) is compared and measured. The principle is to use the equal drive principle of the digital micrometer head screw pair to convert the rotary motion of the screw into linear motion, and convert the angular displacement of the verticality detection ruler into linear displacement. The indication error Δ L=L2-L1 is represented by the line value.

Measurement principle: L1: digital micrometer head travel distance mm; L2: perpendicularity detection ruler reading mm; β 1: standard angle; β 2: Verticality detection ruler angle; R: The distance between the axis of the rotary shaft and the axis of the guide shaft is mm; Δ L: indication error: mm.
