Linear guideway assembly

Abstract

The invention discloses a linear guideway assembly which is convenient to install, capable of reducing frictional resistance, and capable of automatically adjusting gaps. The linear guideway assembly comprises a slide bar, one side of the slide bar is provided with a fixed guide body, and the other side of the slide bar is provided with a guide seat and a movable guide body arranged in the guide seat. The top end of the guide seat is provided with a guide hole, the bottom of the movable guide body is provided with a guide post matched with the guide hole, and the guide post is arranged in the guide hole. A pre-tightening spring is arranged between the guide post and the bottom wall of the guide hole and arranged in the guide hole. Respective guide faces of the fixed guide body and the movable guide body are respectively provided with a plurality of placing holes, and steel balls are arranged in the placing holes, and the respective guide faces of the fixed guide body and the movable guide body are respectively provided with a baffle for preventing the steel balls from sliping off. All the steel balls are extended from corresponding baffles. The linear guideway assembly is mainly used for all kinds of machine tools.

Description

technical field [0001] The invention relates to a guide rail assembly, in particular to a linear guide rail assembly. Background technique [0002] Linear guide rail components are widely used in various machine tools. The structure of a traditional linear guide rail assembly generally includes: a sliding bar and guide bodies arranged on both sides of the sliding bar. The disadvantages of this kind of linear guide rail assembly are: the clearance accuracy between the sliding bar and the guide body is high, and the installation is relatively difficult; moreover, the frictional resistance is relatively large, and the wear and tear is serious after long-term use, resulting in the gap between the sliding bar and the guide body. Increased, thus affecting the straightness of the slider operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a linear guide rail assembly which is easy to install, can reduce friction...
