Problems solved by technology

[0003] Due to the structural limitation of the traditional rolling guide block, the guide rail block can only bear load in one direction. In order to realize the two-way load bearing, two guide rail blocks need to be stacked and installed in reverse, which greatly increases the size of the mechanism in the bearing direction and improves the stability. reduced, the scope of application is limited

Abstract

The invention discloses a two-way bearing heavy load guide rail pair. The guide rail pair comprises a guide rail frame provided with a guide rail groove, wherein a self-tensioning slide block matched with the guide rail groove is formed in the guide rail groove; pin roller rows are arranged between two sides of the self-tensioning slide block and the inner wall of the guide rail groove; the pin roller rows consist of pin roller columns and pin roller retainers; the self-tensioning slide block comprises a first slide block and a second slide block which can be separated from each other; a positioning boss is formed on the first slide block; a positioning groove matched with the positioning boss is formed in the second slide block; and the inner side of the first slide block and the inner side of the second slide block are connected in a matched mode by virtue of the positioning boss and the positioning groove. Two-way bearing of the mechanism is realized, and the two-way bearing heavy load guide rail pair disclosed by the invention has the advantages of high bearing capacity and compact structure.

Description

technical field [0001] The invention belongs to the technical field of guide rail pair structure, and in particular relates to a two-way force-bearing heavy-duty guide rail pair. Background technique [0002] The traditional heavy-duty rolling guide block generally includes: a slider body, a protective plate, an end cover, a guide piece, a roller and a retainer, and the rolling body performs a circular motion. The method of use is to install the rolling guide block on the guide rail surface of the moving parts. At least two guide rails are used for each guide rail. The number of guide rail blocks depends on the length of the guide rail and the size of the load. The matching guide rails are mostly inlaid steel quenching guide rails. When the moving part moves, the guide rail surface of the roller support part rolls between the body and at the same time rolls circularly around the body. The rolling guide block is characterized by high rigidity, large load-carrying capacity, a...
