APPARATUS FOR VERIFYING BORE GAUGE METERS AND PARTS IN THE FIELD OF LINEAR LENGTHS (), OUTSIDE DIAMETERS () AND INSIDE DIAMETERS ()

摘要

The invention relates to an apparatus for individually checking some bore gauges included in a kit and by means of which there are measured lengths, outside and inside diameters. According to the invention, the apparatus comprises a cylindrical-shaped body (7) whose thickness is at least equal to the width of a feeler of a bore gauge (5) to be checked, having in the centre the shape of an overturned equilateral triangle, with the apex inclined leftwards, which is the "zero" point, whose plane sides are measuring surfaces, the apex and the bisector- the latter being the axis of the apparatus - meeting in a point on the face of an anvil (2) whereto there is fastened a nut (1) and which is the "zero" point, in relation to which the initial adjustments and later verifications are performed, on an axis to the right there being placed a mobile mandrel (8) with a face plane parallel to the face of an anvil (2) which is the point "zero", which may be moved manually to the left or to the right with a clutch nut (9) with a micro-metric screw or a screw with digital display, a guide piece (11) centering the bore gauge (5) subjected to verification on the axis of a blocking handle (10) fixing the desired size, some insulating plates (3) thermally insulating the bore gauge (5) having an actuation cone (6) and some equidistant feelers (4) subjected to verification.
