Title The Structural Design of the Static Load Test Platform for Linear Rolling Guides
Abstract
In the process of mechanical industrial automation, linear rolling guide have already became an indispensable guide components or features in machine tools, precision instruments, industrial robot.
According to the structural features of linear rolling guide and international standards on the definition of the static load, a simple measurement of static load has been determined ,and the static load test has been designed by the overall structural. And then determine the scope of application of the test platform designed for the selection and design of the parts, and to determine the specific size and select the appropriate force sensor and contact displacement sensors.
In the entire structural design process, the three-dimensional model of the static load test platform has been set up, and the corresponding two-dimensional drawings have been drawn. Under meeting its function the shape of the structure of the static load test platform also has been Optimized. The strength and hardness of the key components should be checked.
Keywords Linear rolling guide Static load Test platform Structural design
