| With the development of social science and technology, production efficiency needs tobe improved, a variety of machine tools and devices at the overloaded direction to thehigh-speed high-precision processing, the following issues need to be solved: due to linearmotion guide, the coefficient of static friction is small,bearing capacity, good rigidity, long lifecharacteristics, and processing to facilitate easy assembly can be achieved by high feed speedand positioning accuracy, has been increasingly common application, but the rolling Guide forits rolling contactsurface is the point or line, compared with conventional planar sliding railPowerPhone contact, the damping performance is relatively worse. Affect the machiningaccuracy and service life. Therefore, the linear guides feature a variety of mechanical devicescommonly applied, the damping function should be solved.In this paper, in-depth study on the basis of the principle of damping and linear guidesstructure, combined with mechanical devices commonly used damping devices, anddeveloped a new type of linear guides damper. A detailed study of the parallel gap filmdamper technology, and through the company’s deduction, calculation and analysis ofimportant parameters film damping is analyzed for the main performance of the product, andto suppress the motion characteristics of a theoretical analysis to prove that the new thesuperiority of the product; and Pro/E to complete the three-dimensional detailed modeling ofthe clamp device.Secondly, we completed the damper damping design of the test device through thedevice by means of experiments to get more realistic film damping, to provide a basis forfurther research and design the best film damper program.Finally, according to the need to clamp the geometric model of the ontology to simplify,to get the ANSYS finite element model and modal analysis to the clamped state of the parts ofthe former six natural frequency order, for further the dynamic characteristics analysis of thefoundation. |
