Problems solved by technology

[0003] Bearings are mass-produced in the factory, which requires high assembly dimensional accuracy. In actual production, due to factors such as technology and processing accuracy, it is inevitable that some bearing outer rings will be out of tolerance, which will affect assembly and assembly. The final quality affects the use effect of parts, so it is necessary to carry out bearing size inspection before assembly. Most of the existing bearing size measurement methods use manual instrument measurement. This measurement method is prone to errors. When high-precision matching is required It will have an impact, and a large number of bearings need to be measured in batches during processing. Manual measurement is time-consuming and laborious, and the work efficiency is low. Therefore, we propose a bearing quality inspection device for measuring inner and outer diameters. For this reason, we propose a bearing quality inspection Measuring device for inside and outside diameter

Abstract

An internal and external diameter measuring device for bearing quality detection disclosed by the present invention comprises a first conveyor belt, a second conveyor belt and a third conveyor belt, the second conveyor belt and the third conveyor belt are symmetrically distributed, the first conveyor belt is located at a position close to the input end of the second conveyor belt, and a first support is fixed between the tops of the first conveyor belt and the second conveyor belt. According to the device, the three sections of conveying belts are designed, the inner and outer diameter online measuring instrument and the disc feeding mechanism are designed among the conveying belts, the disc feeding mechanism automatically conveys a clamped bearing to be measured to the position below the inner and outer diameter online measuring instrument, and whether the bearing is qualified or not is automatically measured through the instrument; after measurement, defective products and qualified products are classified, the automation degree is high, the bearing measurement efficiency is greatly improved, time and labor are saved, and the device is suitable for online measurement of batch bearings.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to an inner and outer diameter measuring device for bearing quality inspection. 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. [0003] Bearings are mass-produced in the factory, which requires high assembly dimensional accuracy. In actual production, due to factors such as technology and processing accuracy, it is inevitable that some bearing outer rings will be out of tolerance, which will affect assembly and assembly. The final quality affects the use effect of parts, so it is necessary to carry out bearing size inspection before assembly. Most of the existing bearing size measurement methods use manual instrument measurement. This measurement method is prone to errors. When high-...
