The working principle and process for using of the utility model: after the utility model installs, measurement railway signal AX after
It when electric appliance sample surface roughness, places the sensors on sample surface to be measured, drives sensor to carry out constant speed by instrument and slide,
Sensor is provided in standard, must take one when evaluating roughness by the roughness on built-in sharp keen probe records surface to be measured
Section can reflect the minimum length of machined surface roughness characteristic, it includes one or more sample lengths, sample length and sample
Overall length and sample surface degree of roughness are closely related, and at this moment vernier paper jam can be used to be sampled measurement of length, work as survey
When measuring sample length, internal measure-hand 4 and exterior measuring measuring jaw 5 are wiped clean with soft cloth, close up it, checks vernier scale 8 and master
Whether the zero graduation line of measuring scale 1 is aligned, if alignment can be carried out measuring, to keep zero error in mind if without alignment, swim
Target zero graduation line is positive zero error on the right side of blade zero graduation line, makes negative zero miss on the left of main 1 zero graduation line of measuring scale
Difference, when measurement, the right hand holds main measuring scale 1, thumb moving cursor ruler 8, make sample to be tested length be located at exterior measuring measuring jaw 5 it
Between, when being tightly affixed with measuring jaw, i.e. readable, when measuring the outside dimension of part, the on line of two measuring surface of vernier caliper is answered
Perpendicular to measured surface, cannot skew, when measurement, main measuring scale 1 can be gently shaken, put positive upright position, otherwise, interior survey
If measuring jaw 4 on errors present, first opens the movable measuring jaw of slide calliper rule, so that measuring jaw is freely sticked into workpiece, part is reclined
On internal measure-hand 4, main measuring scale 1 is then moved, so that movable measuring jaw is contacted part with slight pressure, fine motion can be tightened at this time
Fastening screw 3 on device makes internal measure-hand 4 contact part and reads size, never can be two measuring jaw tune of vernier caliper
It saves close to being even less than institute's measurement ruler cun, snaps into part up slide calliper rule are compulsory, doing so can be such that measuring jaw deforms, or make to measure
Face premature abrasion makes slide calliper rule lose due precision, and fixes to multiple types relay contact to reach and protect test table
The purpose in face, this testing tool back side attached a composite test fixed cell 2, divides four on composite test fixed cell 2
Current four class contact of relay is respectively tested in region, has both guaranteed that sample will not move in roughness dynamic test in this way
It is dynamic to cause data misalignment, and sample surface to be measured can be made to be sufficiently exposed under test equipment and play a certain protective role, it mentions
The high service performance of railway signal AX relay contact roughness composite test tool.
