Automatic measuring instrument for inner bearing bore

Abstract

The invention, which belongs to the technical field of bearing measurement, relates to an automatic measuring instrument for an inner bearing bore, particularly to an apparatus for detecting an inner bearing bore rapidly. The automatic measuring instrument is composed of a bottom plate, a first side bracket, a second side bracket, a measuring mechanism, a bearing pushing mechanism, a switching mechanism and a feeding mechanism. The measuring mechanism consists of a measuring cylinder, a moving plate, a measuring head and a measuring claw; a driving end of the measuring cylinder is connected with the moving plate; the measuring head is connected with the driving end of the measuring cylinder; the measuring claw is connected with the front end of the measuring head; a measuring hole is formed in the first side bracket by corresponding to the position of the measuring head; and the measuring head can pass through the measuring hole. The switching mechanism is arranged at one side of the measuring mechanism side by side; the bearing pushing mechanism is arranged at the outer side surface of the first side bracket; and the feeding mechanism is arranged on the first side bracket. Therefore, a measuring error caused by the measuring apparatus is eliminated; the measurement efficiency is improved; the production task of the follow-up procedure is not affected; the measurement accuracy is enhanced; long-term uninterrupted measurement is realized; and the measurement error is controlled to be less than 0.5 micrometers.

Description

technical field [0001] The invention relates to an automatic measuring instrument for bearing inner holes, in particular to a device capable of quickly detecting bearing inner holes, which belongs to the technical field of bearing measurement. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The inner hole of the bearing is the part where the bearing is installed. Only by ensuring the accuracy of the inner hole of the bearing can the installation and practicality of the bearing be guaranteed. [0003] At present, most of the bearing inner hole testing equipment used in workshops are contact measuring equipment, which is also a relatively mature technology. However, for ultra-miniature bearings with small inner holes and high precision requirements, contact measurement cannot me...
