a linear guide

Abstract

The invention discloses a novel linear guide rail which comprises a guide rail body and a sliding block matched with the guide rail body. The guide rail is in an H shape, a plurality of polished shaft mounting grooves are formed in the top of the guide rail body in the sliding direction, and cylindrical polished shafts are mounted in the polished shaft mounting grooves. A plurality of sliding way mounting grooves are formed in the face, in contact with the polished shafts, of the sliding block, and arc-shaped sliding ways matched with the polished shafts are mounted in the sliding way mounting grooves. The sliding ways are fixed in the sliding way mounting grooves through bolts. In the work process, the polished shafts are in direct contact with the arc-shaped sliding ways, sliding friction occurs, and when the polished shafts or the sliding ways are abraded, the corresponding components can be replaced. The guide rail body is in hollow design, reinforcing ribs are arranged in the guide rail body, and under the condition of not influencing use, materials are saved, and cost is reduced. The novel linear guide rail is simple in structure and low in manufacturing difficulty and has good application prospects.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a linear guide rail. Background technique [0002] Linear guides are widely used in machinery manufacturing, hardware processing and other fields, and their performance directly determines the precision of machining. At present, balls are mostly used in linear guides as a method to reduce friction and improve precision. This kind of ball guides requires balls, return devices and other devices inside the slider. The design is complicated, the manufacturing is difficult, the price is high, and there are many installations and debugging Inconvenience. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of complex design, difficult manufacture and inconvenient debugging in the prior art, and provide a linear guide with simple structure, easy implementation, and quick replacement when parts are worn out. [0004] In order to achieve the above ...
