Linear guide rail pair structure with high dust prevention performance

Abstract

The invention relates to a linear guide rail pair structure with the high dust prevention performance. The linear guide rail pair structure with the high dust prevention performance comprises a guide rail, a sliding block, rolling bodies and rolling body retainers, wherein the sliding block is installed on the guide rail and can slide on the guide rail, and the rolling bodies and the rolling body retainers are arranged between the guide rail and the sliding block. The linear guide rail pair structure with the high dust prevention performance is characterized in that the front side and the rear side of the sliding block in the moving direction are respectively provided with an end face double-lip scrap scraping plate made of elastic wear-resistant materials. Each end face double-lip scrap scraping plate is provided with a double-lip scrap scraping hole corresponding to the guide rail in shape, the orifice of each double-lip scrap scraping hole is provided with two lips, and each lip is of an inclined tongue structure with the tongue tip outwards. A linear guide rail pair has the high dust prevention structure and advantages. The two novel metal retainers are installed for the guide rail and the rolling bodies of the sliding block and have the advantages of being high in rigidity, free of backlashes, high in reversible speed and the like.

Description

technical field [0001] The invention relates to a pair of linear guide rails, in particular to a structure with high dustproof performance of the pair of linear guide rails. Background technique [0002] Linear guide rail pairs are widely used on linear motion bodies on automation equipment and precision machinery. Due to structural design and manufacturing reasons, the general kinematic pair has poor dustproof performance, large manufacturing dimensional tolerance and poor usability of the cage. Therefore, the service life of the guide rail pair is short, which affects the accuracy and safe operation of the entire equipment, and reduces the equipment. service life. Contents of the invention [0003] The invention provides a structure with high dust-proof performance of a linear guide rail pair, the main purpose of which is to solve the problem that when the existing linear guide rail pair is in use, dust or pollutants on the guide rail are easily removed as the slider mo...
