Abstract:
An improved apparatus for detecting the intensity of shot
peening by detecting at least one of the number of shot that
have collided with the apparatus and the intensity of the
colliding shot, comprising a box-like case having an opening
at its top; a first resilient member disposed under the top of
the case; a hollow supporting member resiliently supported
in the case between the first resilient member and a second
resilient member which is mounted in the case, the hollow
supporting member including a third resilient member
mounted therein; a shot collision propagating member supported
by the hollow supporting member to close the opening
of the top of the box-like case by way of the first resilient
member, the shot collision propagating member producing
and propagating an elastic wave when colliding with a shot;
a transducer, for receiving the propagating elastic wave from
the shot collision propagating member and converting the
elastic wave to high frequency signals, disposed in the
hollow supporting member and resiliently supported by the
third resilient member such that a top surface of the transducer
contacts a lower surface of the shot collision propagating
member; and a cable passing through the hollow
supporting member so as to be connected at one end to the
transducer and to be connected at the other end to a
measuring circuit.
