How to measure the accuracy of the outer diameter of the hydraulic piston rod?
Nov 22, 2018

The hydraulic piston rod is a connecting component that is frequently used in motion-executing parts such as oil cylinders, and has high technical requirements for supporting the piston to perform work. It is used in most mechanical products. Hydraulic piston rods have a wide range of applications, so how to measure the accuracy of their outer diameter?

 

Currently, for the accuracy measurement of the outer diameter of the hydraulic piston rod, we can usually use the laser caliper to measure. The laser caliper can measure up to 59mm, and its highest precision can reach 5 microns. Therefore, it is quite suitable to use the laser caliper to measure the outer diameter of the piston rod.

 

When measuring the accuracy of the outer diameter of the hydraulic piston rod, the laser caliper used is mainly composed of a transmitter and a receiver, and the light of the laser light-emitting diode forms a light curtain through the optical system. Then the shadow image of the piston rod can be formed on the linear CCD array through the telescope system. We only need to calculate its size through the signal processor, and it provides a very convenient measurement method for detecting the outer diameter of the object.http://www.xhychromerod.com/
