Abstract

The invention discloses an ultra-wide-span roller guide rail structure. The ultra-wide-span roller guide rail structure comprises a guide rail body, wherein a sliding body is installed on the guide rail body; a fixing frame is installed at the bottom of the guide rail body; side plates are integrally formed and fixed on the left side and the right side of the sliding body; sinking grooves are pre-formed in the inner sides of the side plates; rollers are installed in the sinking grooves; arc-shaped grooves are pre-formed in the centers of the left ends and the right ends of the rollers; convexcolumns with hemispherical end parts are arranged in the arc-shaped grooves in an abutting mode; the convex columns are welded and fixed at corresponding positions in the sinking grooves; rolling grooves are pre-formed in the left side and the right side of the guide rail body; and the rollers abut against the rolling grooves. According to the ultra-wide-span roller guide rail structure, a stressframe is composed of two hollow triangular blocks which are arranged in a forward and reverse mode, on the physical basis that a triangular structure is matched and has stability, the overall weight of the stress frame is reduced while the structural stability is ensured through hollowing, so that the load of a supporting structure of the guide rail body is reduced, the effective load capacity ofthe guide rail can be improved, and the use capacity is improved.

Description

technical field [0001] The invention belongs to the technical field of guide rail equipment, in particular to an ultra-wide-span roller guide rail structure. Background technique [0002] There are generally two types of linear guides widely used at present, one is rolling type and the other is sliding type. Rolling linear guide is a kind of rolling guide, which uses steel balls or rollers to perform infinite rolling between the slider and the slide rail. Circulation, so that the load platform can easily move linearly along the slide rail with high precision, and its friction coefficient can be reduced to 1 / 50 of that of the traditional slide guide, so that it can easily achieve the positioning accuracy of μm level. [0003] Among them, under the condition of ultra-wide span, the guide rail needs to meet the needs of traditional rolling guidance, and at the same time, it needs to take into account the problem of support rigidity. The traditional support problem mostly relies...
