A kind of high-precision gap measurement table
Technical field
The present invention relates to high-precise meter field, specifically a kind of high-precision gap measures table.
Background technique
For measuring the spacing in gap, usually measured using clearance gauge, clearance gauge, which is one group, has different-thickness differential
Stalloy composition gauge need to remove the dirt and dust on clearance gauge before measuring gap due to the characteristic of stalloy, make
Used time is also required to a piece of or several pieces overlappings and is manually inserted into gap, operates very complicated;Plug is moved in addition, filling in clearance gauge and pulling back later
Ruler, slightly sense drag after can readout value, the gap width measured at this time is the numerical value that marks close on clearance gauge, and measurement is very not
Accurately, while back and forth it pulls clearance gauge to also wear out clearance gauge, is increased using the time longer data error that will lead to, service life is short;
Therefore a kind of device of urgent need solves the above problems.
