Abstract
Currently, the most common machinery components is the common standard bearing. In particular, the rotary mechanical spare parts and equipment, the bearing plays an important role. Deep groove ball bearings as the most common type of a rolling bearing, is important for its assembly clearance control, which requires high-precision bearing outer channel diameter, high-efficiency measurements.
This paper describes the current deep groove ball bearings common method of measuring channel diameter on the basis of analysis of the functional requirements of deep groove ball bearing-line automated inspection system, we proposed a set of linear guides and basic mechanical structure as an automatic measuring system skeleton, pneumatic mechanical structure as an automatic measuring heart of the system, the sensor features as an automatic measurement system, programmable controllers and IPC as an automatic measuring system of the brain and cost-effective automation of rolling bearing outer channel diameter measurement system.
This paper describes the mechanical design of automatic measurement system outer diameter of the channels, including the feeding mechanism, push-in/push-out mechanism, lifting mechanism and measurement organizations. According to the outer diameter of the channels testing requirements, this paper completed the measurement and control system hardware design and selection, introduced the software part of the process. Control system consists of I/O interfaces three-part measuring system operation control, the channel diameter detection and PLC.
The outer diameter of the channel detection apparatus designed in this paper can achieve automatic feeding of the outer ring, automatically determines the ditch, automatic acquisition and analysis functions such as diameter amount.
