Manual grating digital display small angle inspection instrument

1、 Instrument Introduction:

XR-GXJ-1S typeManual grating digital display small angle inspection instrumentOur company strictly followsJJG300-2002 "Verification Regulations for Small Angle Inspection Instruments" is a precision indication verification instrument developed and produced for measuring small angles.

2、 Instrument usage:

XR-GXJ-1S typeManual grating digital display small angle inspection instrumentUsed for verifying and calibrating the angle indication errors of measuring instruments such as frame level, strip level, composite level, electronic level, and autocollimator, widely used in metrology and testing departments and enterprise metrology laboratories.

3、 Structural principle:

The main standard of this instrument adopts two precision grating sensors as positioning indicators (electronic subdivision circuit, microcontroller, LED display) and a precision granite specially designed working surface with a span of 500mm, with circular tabletops at both ends, adjustable structure, and composition.

4、 Working principle:

This instrument consists of two grating type micrometers for positioning and zeroing. Taking advantage of the large measurement range of grating type micrometers, it can replace measuring blocks and generate standard angles by combining fine adjustment parts to verify the angle error of the tested measuring tool. The schematic diagram of the principle is as follows:

The two indicators A and B on the instrument are generally used for positioning. The distance between the measuring axes is (500mm ± 0.04). Generally, a measuring block with a size of 1mm is placed between the spherical measuring head of the two indicators and the ribbed table. Alternatively, a measuring block with a size of 1mm can be placed under only one indicator's measuring head. Adjust the indicator to set its reading after zero. According to the size of the detected angle, select another size of gauge block (replaced by a grating system) to replace the gauge block under the measuring head of one indicator (which can be replaced by a grating system), and use the lifting micro screw to adjust the bridge shaped worktable to change the angle position until the readings of the two indicators are at their original positions (zero position). At this point, the instrument generates the required standard angle α, and the detected angle is compared with this angle α to obtain the result.

5、 Instrument features:

1. Intuitive data observation (displayed on LED digital tubes);

2. The grating micrometer has a large stroke (eliminating the need to replace measuring blocks, reducing complex calculations and evaluations);
