Abstract

The invention discloses an online detection tool for the excircle size of a large-scale dense ball bearing ring, belongs to the technical field of precision machinery manufacturing, and aims to solve the technical problem of online detection of the excircle size of the large-scale dense ball bearing ring. The online detection tool comprises a bottom plate, a first supporting cushion block assembly, a measuring meter assembly, a second supporting cushion block assembly and a measuring rod assembly. The left and right sides of the bottom plate are respectively provided with a plurality of groups of threaded bottom holes, the first supporting cushion block assembly, the measuring meter assembly, the second supporting cushion block assembly and the measuring rod assembly are fixed on the bottom plate through screws, and the relative positions can be adjusted through the installation of different screw bottom holes. When the detection tool is used for measuring the outer circle size of 1000 mm, the measurement precision can reach 0.003 mm, the problem of online detection of the outer circle size of the large dense ball bearing ring can be solved, and the machining precision and efficiency are improved.

Description

technical field [0001] The invention belongs to the technical field of precision machinery manufacturing, and in particular relates to an on-line detection tool for the outer circle size of a large dense ball bearing ring. Background technique [0002] Modern large-aperture telescopes continue to develop in the direction of large-aperture, high-precision, and high-carrying capacity. The large ball bearing ring is one of the key parts of the telescope shafting. Its accuracy directly affects the shaking of the telescope body and the measurement accuracy of the telescope. [0003] Large dense ball bearings have two notable features: large size and high precision. In particular, the processing of the bearing ring adopts the base hole system. The outer circle of the bearing ring needs to be processed according to the transmission size. During the processing, the size of the outer circle of the bearing ring needs to be checked online with high precision. The diameter of large de...
