3 Overview
The inner diameter gauge is an indicator table (percent dial or dial gauge) and a table set with a lever drive or linear drive
A measuring instrument that converts a linear displacement of a measuring element into a pointer angular displacement or a numerical value. Mainly used for comparison
Measure the inner diameter of the workpiece.
According to its structure, it is divided into three types. positioning bridge (lever type or raceway type), spring type and steel ball type. Its shape is schematic
The figures are shown in Figure 1, Figure 2 and Figure 3.
4 Measurement characteristics
4.1 Surface roughness of the measuring surface of the probe
4.1.1 Inner diameter table with positioning bridge can change the measuring head, the measuring surface of the movable probe and the surface of the contact bridge contact surface
The roughness Ra does not exceed 0.2 μm.
4.1.2 The surface roughness Ra of the measuring surface of the spring probe of the spring type inner diameter meter shall not exceed 0.1 μm.
4.1.3 Measurement of the steel ball type inner diameter gauge The surface roughness Ra of the steel ball and the positioning steel ball does not exceed 0.05 μm.
4.2 Spherical radius of the probe
The spherical radius of the interchangeable probe and the movable probe with the inner diameter gauge of the positioning bridge and the spherical half of the spring-loaded inner diameter gauge
The diameter is less than 1/2 of the lower limit of the measurement. When comparing with a radius template of the corresponding size, a light gap appears on both sides of the template.
4.3 indicator
The matching special indicator table complies with the requirements of JJG34-1996.
4.4 Working stroke of the active probe
4.4.1 Internal diameter dial gauge with positioning bridge The working stroke of the active probe is shown in Table 1.
