Research On Digital Detection System Of Bearing Ring Processing Quality

As an important part of the machinery industry,the bearing industry is actively exploring digital manufacturing and intelligent manufacturing under the impetus of “Made in China2025”.The inspection of the processing quality of the bearing ring is an dispensable part of the bearing production process.At present,it is still in the state of manual sampling inspection.This traditional inspection method can no longer meet the development needs of the current bearing enterprises for digitalization and intelligence.A precise and efficient inspection method is needed.This paper researches and develops a digital automatic detection line for bearing ring processing quality.The main research contents are as follows:Research on detection methods and measurement techniques.Based on the analysis of the existing bearing ring detection method,the whole circle full information digital detection method is established.In order to improve the detection accuracy,the opposite contact sensor arrangement and the contact and non-contact detection technology are developed.Through the development of the programmatic automatic detection function module,the full coverage of the inspection project and efficient flow operation are realized.Development of measurement equipment and core components.Focusing on the core element of positioning accuracy,the self-centering and adjustable special fixtures for different positioning benchmarks have been independently developed,which realizes the automatic and precise positioning of the testing equipment.At the same time,the core measuring sensor is selected according to the micrometer-level detection accuracy requirements.The components are precisely calibrated.In conjunction with this,the development of the measurement system and measurement mechanism,the development of the auxiliary motion control and actuator development of the component to be tested,and the entire inspection automatic line such as the dedicated handling robot were completed.The component’s repeat positioning accuracy,measurement automation,and inspection tempo matching the machining process are ensured.Research on control systems.Based on the overall scheme determined by the automatic detection line,based on the control object and control requirements,the main electrical control loop and the sub-electrical control loop of each sub-testing station are designed by EPLAN Electric electrical design software,and the corresponding electric control cabinet and pneumatic transmission control system are built.The control program and humancomputer interaction control interface were written using the TIA Portal software platform.Development of visualization software.The Lab VIEW-based inspection data visualization software was developed.The OPC technology is used to build a digital monitoring platform for bearing ring processing quality.The platform uses serial communication technology to extract measurement data.Combined with the data analysis and processing of MATLAB software,the data is stored while the detection parameters are obtained.In addition,the platform is equipped with a device operation status monitoring module to ensure safe and reliable operation of the detection automatic line.Through actual testing,the digital detection line can meet the automatic detection requirements of the bearing ring processing quality.The successful development of this system will provide an accurate and efficient detection method for bearing manufacturers,which has certain engineering value for promoting the development of digitalization in China’s bearing industry and even machining industry.
