Abstract
Manual plug comparator for verifying inside diameters of mechanical parts comprising a perforated support plate, a first member of substantially U shape fastened to the plate and a second member having a base fastened to the first member, two elastically yieldable sections and two arms which are movable due to the deformations of the elastically yieldable sections. The two arms bear the elements of a position transducer and, at their free ends respective feelers adapted to touch the part to be checked.
Claims10
A comparator for the checking of linear dimensions of mechanical parts comprising:
- a first support element defining a perforated plate;
- a second support element comprising essentially a rigid first member fastened to said perforated plate and located on one side of the plate;
- a second member fastened to said first member, said second member defining a first rigid portion, second and third rigid portions which define measurement arms and two elastically yieldable sections arranged between the first rigid portion and the second and third rigid portions, for permitting measurement displacements of the arms;
- two feelers fastened to the measurement arms, respectively, so as to come into contact with the part to be checked, said arms passing through a hole in said plate and bearing said feelers at ends located, with respect to the plate, on a side opposite that on which said rigid first member is located;
- and means adapted to detect the mutual position of the measurement arms.
