Complex Model of Two-Axis Telescopic Covers: Dimensions and cover deflection avoidance

Original language description

This paper describes a design of two-axis telescopic covers of machine tools. It also describes a mathematical model of dimensions of two-axis covers, static model of cover deflection and model of strip stiffener. Two-axis cover is system of movable plates allowing movement of two perpendicular axes. Relative movement of plates is assured by four scissor mechanisms guiding corners of all plates. Design of scissor mechanism also allows mutual preload of all plates essential for proper sealing effect of polyurethane wipers. Model of dimensions calculates optimal dimensions (to achieve minimal space necessary for covers to move) and avoids collisions of cover plates. Preload of plates and reaction forces of wipers cause unwanted deflection of plates thatcan result in gap between sealing wiper and plate. This situation is predicted by a static model of cover deflection. This situation can be avoided by a rounded strip stiffener welded onto cover plate. This process creates contrary deform
