Linear guide rail provided with dustproof structure

Abstract

The invention discloses a liner guide rail provided with a dustproof structure. The linear guide rail comprises a sliding seat, a guide rail body, the dustproof structure and a rolling structure. The dustproof structure is composed of a pair of dust covers. The rolling structure is composed of a pair of ball bearings and a U-shaped clamping spring. According to the linear guide rail with the structure, the overall structural design is ingenious, the technical problems that when the linear guide rail conducts linear motion on the guide rail body along with the sliding seat, dust or pollutants on the guide rail body are prone to being carried into the sliding seat, so that the practical precision of the whole guide rail body is lowered, and the service life of the integral guide rail body is shortened are solved. Meanwhile, the linear guide rail serves as a precise workpiece, and the utilization effect in space is excellent. When the linear guide rail slides horizontally, the deviation of the sliding seat in the gravity direction is extremely low, and excellent solutions are provided for modern science and technology development of interdisciplinary multi-technology application and combination. In addition, compared with linear guide rails of other structures in developed countries, the production and manufacturing cost of the linear guide rail is lower.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a linear guide rail with a dustproof structure. Background technique [0002] Linear slide rails, also known as line rails, slide rails, linear guide rails, and linear slide rails, are used in linear reciprocating motion applications, and can bear a certain torque, and can achieve high-precision linear motion under high load conditions. In the mainland, it is called linear guide rail, and in Taiwan, China, it is generally called linear guide rail and linear slide rail. Linear guides can be roughly divided into three types: roller linear guides, cylindrical linear guides and ball linear guides. It is used to support and guide moving parts, and make reciprocating linear motion in a given direction, and according to the nature of friction, linear motion guide rails can be divided into sliding friction guide rails, rolling friction guide rails, elastic friction guide rails, fluid friction gui...
