Study On Dynamic Characteristics Of Oscillating Type Polishing Grinding Head

The polishing grinding head is the most core part of the polishing machine.The grinding block is directly in contact with the tile,and the main function is to realize the polishing and grinding of the surface of the ceramic tile.The surface of the grinding block of the polishing grinding head is arc type,and the contact with the surface of the ceramic tile increases the working pressure effectively and improves the polishing efficiency.The two tooth difference external meshing double planetary gear system and CAM mechanism adopted by the oscillating polishing grinding head realizes the reciprocating oscillation of the drive and slave swing rod,while the acceleration impact of the CAM driving form under the high-speed motion and the machining errors of the parts will affect the processing quality and the broken brick rate of the tile polishing.The dynamic characteristics of the polishing grinding head are closely related to the broken brick rate and polishing quality,to improve the dynamic characteristic of the polishing grinding head can effectively improve a series of problems in polishing process.Polishing grinding head is composed of multiple grinding head installed in together,and feed and swing,swing speed and related parameters Settings affect the polishing efficiency and energy consumption and so on the parameter optimization as far as possible to achieve high efficiency low energy consumption,improving the economic benefit and social benefit.Based on the working principle of the polishing machine,polishing grinding head structure and motion forms of analysis and research,polishing grinding head kinematics mathematical model is set up,a dynamic mathematical model of the polishing grinding head is set up using mechanical vibration theory,obtaining vibration characteristics of polishing grinding head in the polishing process,analyzing from the points of view of vibration study suppress vibration method is scientific.By using the theory of multi-body dynamics analysis dynamic characteristics of grinding block of polishing grinding head in the process of polishing,it is concluded that the qualitative relationship between polishing speed and dynamic characteristics,analyzes the excessive polish and the leakage polish in the polishing process,and puts forward improving methods.The polishing grinding head experiment platform is built,and the optimal polishing parameters are obtained through experiments.This research can provide a theoretical basis for the study of ceramic polishing machine in China,and provide the reference value for the development of polishing machinery industry.
