Miniature bearing outside diameter measuring instrument

Adjust fulcrum and points at the same height, the adjustment method is as follows: (1) preliminary adjust the pivot point 1 in the middle of the plate location. And then coated with a little red on the ring diameter, and the ring base of quasi plane contact instrument plate fulcrum cant 1 close to delimit ring and rotating ring seal, from row printing marks on the ring diameter ring chamfer in final fastening protection 1 lifting clamp screw tighten. (2) to adjust the height of the shaft to help support 2, of the same color as the above method to delimit printing, make axis help support 2 row is printed with the point 1 row of overlap, shows the two fulcrum in the same plane, the height of the rise and fall of fulcrum 2 and then fastening screw (3) slightly loosen the handle 4, move the table frame, on the instrument, adjust the height of the point 3, the measuring point 3 row printing on workpiece with two pivot row printing ・ knob to tighten. After adjusting the two fulcrum and points at the same height of the plane. Adjust the biggest point position, adjustment method is as follows: (1) between the pivot point 1 and point 3 of ring, well contact with the outside diameter of floor, and then a little fastening protection 1 the positioning of the nut. Lateral movement ring, careful observation instrument pointer, when the pointer in the maximum scale, the measuring point in ring outside diameter of the radial line ( Referred to as 'the biggest point) , finally tighten the fulcrum position 1 fixed nut (2) maintain ring is still in its biggest point position, auxiliary pivot 2 near the surface of the ring diameter gently, and with the od table surface contact, at the same time, considering the location of auxiliary pivot 2 perpendicular to the pivot point 1 to point 3 of the attachment on, pay attention to the ring at this time in the point of maximum value remains the same. Then tighten auxiliary pivot 2 fixed nut. (3) with standard parts are on the table, and finally can be measured. On circular deviation measuring diameter instrument D913, adjustment method is as follows: (1) removing the fulcrum 1 and shaft to help support two (2) V frame, in a race to the outer diameter, measuring point contact with the V frame. In order to make the instrument pointer position between in scale, v-shaped adjustable frame in the vertical position of the inclined plate. At the same time must make V frame side with measuring axis line, and make the axis through the ring diameter measurement
