Problems solved by technology

[0003] In the ball linear guide, the traditional slider adopts the rolling cycle of steel balls. Due to the specific structure and circulation mode, the slider will generate a lot of noise during operation, the jump is large, the precision is low, and the operation is complicated during the assembly process. , It is easy to have problems such as stuck steel balls, which greatly affect the product accuracy requirements, and it is time-consuming and labor-intensive. In the later use and maintenance process, it is necessary to add grease and lubricating oil regularly to ensure the smooth operation of the steel balls inside the slider. Does not rust

Abstract

The invention mainly discloses a linear guide rail. According to a technical scheme of the invention, the linear guide rail comprises a sliding block body and sliding columns which are in slidable connection, wherein two sides of the sliding block body are respectively provided with an automatic clearance adjusting device; and each automatic clearance adjusting device abuts against and matches with a sliding column. According to the invention, the internal structure of the sliding block body is changed from rolling transmission to sliding transmission; the sliding block body and the sliding columns are in slidable connection; a unique connection structure and transmission manner are adopted; two sides of the sliding block body are respectively provided with an automatic clearance adjustingdevice; thus, automatic clearance adjustment can be guaranteed in the normal use process, and sliding members and chutes can be closely matched to guarantee walking precision. The linear guide rail provided by the invention can maintain high walking precision in the operation process of the sliding block body, is simple to install and easy to operate, saves labor and improves work efficiency.

Description

technical field [0001] The invention relates to the technical field of linear guide rails, in particular to a linear guide rail. Background technique [0002] Linear sliders can be divided into three types: roller linear guides, cylindrical linear guides, and ball linear guides. They are used to support and guide moving parts and perform reciprocating linear motion in a given direction. [0003] In the ball linear guide, the traditional slider adopts the rolling cycle of steel balls. Due to the specific structure and circulation mode, the slider will generate a lot of noise during operation, the jump is large, the precision is low, and the operation is complicated during the assembly process. , It is easy to have problems such as stuck steel balls, which greatly affect the product accuracy requirements, and it is time-consuming and labor-intensive. In the later use and maintenance process, it is necessary to add grease and lubricating oil regularly to ensure the smooth opera...
