A precision measuring rod with a corner

Abstract

The utility model belongs to the technical field of precision measuring equipment, concretely relates to a precision measuring rod of corner degree, and the new type includes: corner chuck, it includes: the placement part of setting in corner chuck top, the fixed shaft of setting in the placement part, the first installation part of setting in corner chuck one side and the second installation part of setting in corner chuck other side, wherein the placement part is respectively linked with the first installation part and the second installation part, and the included angle between the first installation part and the second installation part is obtuse angle, the measuring rod is set in the first installation part, and is connected with the first installation part sliding, the connecting piece of setting on the fixed shaft, one side is contacted with the measuring rod, and the other side is adapted to be contacted with the dial gauge probe, the precision measuring rod of corner degree through the obtuse angle design of the first installation part and the second installation part makes the measuring rod and the dial gauge probe form certain included angle, thereby reaches the adaptation narrow measurement space, solves the problem of traditional structure interference or multi -point simultaneous measurement interference.
