AI Technical Summary

Technical Problem

When used in low temperature environments, the existing platform brackets cannot effectively deal with the problem of mismatch between the thermal expansion coefficients of the marble platform and the bracket, resulting in deformation of the marble platform due to overconstraint and the tabletop accuracy is reduced.

Method used

A platform bracket is designed, including a frame, a rigid support assembly, a mobile support assembly and a balanced support assembly. Through the combination of a linear guide rail slide mechanism and a balanced support assembly, it achieves a thermal deformation release function while accurately positioning the support.

Benefits of technology

When the temperature changes significantly, the marble platform can be deformed freely to avoid thermal stress, thereby effectively ensuring the tabletop accuracy of the marble platform and is suitable for low-temperature installation and adjustment of space optical cameras and other equipment.

Abstract

The invention relates to the technical field of mechanical engineering, in particular to a platform support and a high-precision marble platform, the platform support is applied to supporting the marble platform, the platform support comprises a frame, a rigid supporting assembly, a movable supporting assembly and a balance supporting assembly, and the rigid supporting assembly is arranged on the first side of the frame; the limiting device is used for limiting the translational motion of the marble platform in the X-axis, Y-axis and Z-axis directions; the movable supporting assembly is arranged on the first side of the frame and used for restraining translational motion of the marble platform in the Y-axis direction and the Z-axis direction. The balance supporting assembly is arranged on the second side of the frame and used for restraining translational motion of the marble platform in the Z-axis direction. Therefore, the marble platform has a thermal deformation release function while being high in rigidity and accurate in positioning and supporting, so that the marble platform can be freely deformed when the temperature is greatly changed, thermal stress is avoided, and the platform surface precision of the marble platform is effectively guaranteed.
