detailed description

A bridge-type measuring ruler for measuring large tapered roller bearings, comprising a base 1, a double leg 2, a single leg 3, a reference level ruler 4, an end screw 5, an eccentric rod 6, a splint 7, a measuring block connecting rod 8, and a connecting rod Rod nut 9, positioning nut 11, positioning rod 12, gauge block 14, angle measuring block 15. The double legs 2 and the single legs 3 are respectively arranged vertically at the two ends of the bottom of the base 1 and symmetrically distributed, fixed on the base 1 with screws 17, so that the base and the two legs are vertically arranged, and the landing points are three points, form a plane. The scraping straightness of the top of the base 1 is less than 0.003mm, and the level of flatness is 0. There are 25 spots on the ruler; the grinding plane accuracy of the reference ruler 4 is less than 0.002mm, and the parallelism is less than 0.002mm. Described datum ruler 4 is arranged on base 1 top surface, is assembled and positioned with positioning pin 13, and datum ruler bottom surface is parallel to base top surface, and its side is perpendicular to base top surface, and perpendicularity is less than 0.05mm. In order to ensure that the difference between the bodies of the reference ruler is less than 0.002mm in the axial direction and no more than 0.01mm in the radial direction, the reference ruler 4 is clamped with screws 18 evenly distributed in the radial direction of the base, and then evenly distributed The bolts 10 and nuts fasten the datum ruler 4 on the base 1.
