Bearing width measuring instrument

Will ring in the middle of the instrument platform position, adjust V in contact with the ring diameter, and making V left ring chamfer heights, then tighten the v-shaped rack set screw. Adjust the table only point contact with sets of side end face, first of all a fake opener cantilever fastening screw, coarse adjustment rotating lifting nut, nut rotation is increased to the left, spin to the right is a decline in bone, when adjusted to table only point away from the set of endface 0. About 3 mm, between the rotation is the only table probe on the surface to the location (in the Must be open typing position) , then tighten the cantilever fastening screws (1) adjust the clamp table set of Jane on the table, only measuring point and the ring surface contact, and the only table values between in whose hands is located in the degree of the fan, then tighten the fixed black silk (2) remove the ring, using standard parts on the table, measure and repeat several times, namely take measurement again, see if only watch the clock in its original position. If there is no change, instrument (3) the error and the table has the adjustment, should first check the table only rod linear displacement transformation for pointer angular displacement is efficacious and tighten the screws are tight, fixed, and then readjust the 2. D913 diameter measuring instrument D913 diameter measuring instrument is mainly measuring ring outside diameter deviation, including outside diameter volume table, diameter change in a single radial plane surface generatrix and circular deviation on reference face of gradient change, also can measure the inner ring within the bay road diameter, diameter changes in quantity, etc. ( 1) Instrument structure of the instrument is composed of base, tablet, instrument rack and positioning of fulcrum, as shown in figure 2. 15, in the bottom only 4 cant on fixed on a piece of high hardness, smooth surface, and have more shaped groove tablet, tablet have two slot, which is equipped with two points for locating ring of protection, base after the side has installed instrumentation table frame, and can be moved up and down
