Description
Technical field
The invention belongs to aviation machine technological equipment for making technology, be specifically related to a kind of pitch diameter of external thread and beat
The measurement apparatus of value.
Background technology
Thread connection, is simple to manufacture due to it and couples reliable, being widely used in aircraft industry.
Particularity due to aircraft industry and the requirement to interchangeability, need to examine at large to the size of thread part
Look into.And the threaded male component higher to some required precisions, when needs detection central diameter is beated, it is common that
The pitch diameter of thread is used to obtain jerk value with the method for the ring gauge tested central diameter of conversion of Small Taper.Its detection
Principle be by simulate the externally threaded fitting that is connected, by the pitch diameter of thread with Small Taper ring gauge screw in part,
Beated by detection ring gauge cylindrical and indirectly obtain jerk value.The shortcoming of this measuring method is: be not the most straight
Connect and measure the jerk value obtained, but use the method indirectly measured, it is impossible to the true reflection actual feelings of part
Condition.2. the shortest when part reach, screw thread one end has again diameter to be more than the step surface of the diameter of thread, makes
Taper ring-ga(u)ge does not has enough strokes to be axially moveable, and the most measured conversion is irrealizable.It addition,
If tested pitch diameter of thread required precision is high, therefore taper ring-ga(u)ge precision will be more very high, it is difficult to
Manufacture, therefore use said method taper ring-ga(u)ge to go to measure, will be the most difficult.
