with particular reference to fig. 3, the fixed fulcrum brackets 130 and the dial indicator mounting brackets 120, 140 are circumferentially distributed on the periphery 112 of the support base 111. The dial indicator mounting bracket 120 and the dial indicator mounting bracket 140 are symmetrically arranged, and the two dial indicator mounting brackets 120 and 140 are circumferentially and symmetrically distributed on two sides of the fixed fulcrum bracket 130.
In order to conveniently and adaptively adjust the size of the thin-wall tapered roller bearing inner ring standard component 210 or the thin-wall tapered roller bearing inner ring 220 to be measured according to different sizes, two sliding grooves 191 and 192 which are crossed are arranged on the upper surface 110a of the base 110, a fixed fulcrum support sliding block 131 is arranged at the bottom of the fixed fulcrum support 130, and the fixed fulcrum support sliding block 131 is arranged in the sliding groove 191 in a sliding manner; dial indicator mounting bracket sliding blocks 121 and 141 are respectively arranged at the bottoms of the two dial indicator mounting brackets 120 and 140, and the two dial indicator mounting bracket sliding blocks 121 and 141 are arranged in the other sliding groove 192 in a sliding manner and are respectively positioned at two ends 192a and 192b of the sliding groove 192; the dial indicator measuring heads on the two dial indicator mounting brackets are opposite and are positioned on the same straight line.
