Product name: Pin Gauge Usage Example
In addition to measuring the inner diameter of holes, it has a wide range of applications.
Hole pitch measurement
Micrometer Calibration
Groove width measurement
Hole inspection with plug gauge
Dovetail measurement
Engine parts inspection
Gear overpin diameter measurement
Gear runout measurement
Hole position measurement
If you insert a pin gauge of diameters d1 and d2 that fits snugly into the holes in the item, the position of the hole (h1, h2) can be found by measuring H1 and H2 .
Measuring runout of gear teeth
A pin gauge is inserted into the gear tooth grooves, and the indicator is used to measure the movement of the pin gauge in and out along the tooth grooves for all tooth grooves to determine the runout of the tooth grooves.
Measuring the inclination angle (1)
The inclination angle θ using a sine bar and a pin gauge with diameter d
can be calculated as follows:
Measuring the inclination angle (2)
By measuring h, the cone angle θ can be calculated as follows:
Hole pitch measurement
By inserting pin gauges of diameters d1, d2, and d3 that fit snugly into the holes in the item and measuring L1 and L2, the hole pitch ( ) can be calculated using the following equation.
Measuring the effective diameter of a screw (three-wire method)
The effective diameter E is calculated by E=M-3d+0.866025p
(for metric and unified threads) .
