Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a guide rail protective cover for numerical control machine tools. Background Art

[0002] The parts that support and guide the moving components to move along a certain trajectory are called guide rails, and are often referred to as guide rails. The motion trajectory of the moving parts can be straight, circular or curved. Rolling circular guides can be classified as rolling thrust bearings, and curved guides are rarely used in machinery. Guide rails are a very important component in the machine. However, during the operation of CNC machine tools, guide rails are often prone to dust and impurities, affecting normal use or even damage, causing great economic losses. For this reason, protective devices for machine tool guide rails are particularly important.

[0003] For example, a CNC machine tool guide rail sealing isolation protective cover disclosed in the authorization announcement number CN211072833U includes a first protective cover body, a second protective cover body, a third protective cover body and a sealing strip, the left and right outer surfaces of the first protective cover body are fixed with protrusions, the inner wall surface of the second protective cover body is provided with a slide groove, the rear of the second protective cover body is connected to the third protective cover body, the front of the first protective cover body is fixed with a first fixed plate, and the inner wall surfaces of the second protective cover body and the third protective cover body are both installed with sealing strips. The CNC machine tool guide rail sealing isolation protective cover is provided with a first protective cover body, a second protective cover body and a third protective cover body made of metal material, and has better pressure resistance than the traditional flexible accordion-type protective cover, and is provided with a sealing strip to prevent debris from entering the interior of the guide rail body, which effectively protects the guide rail body and increases the overall sealing and isolation effect. However, the utility model lacks heat dissipation measures and flexible installation and adjustment mechanisms, which is not convenient for heat dissipation during the guide rail operation and adapting to machine tool guide rails of different specifications and types. For this reason, we propose a CNC machine tool guide rail protective cover, which solves the guide rail heat dissipation and installation and adjustment problems, expands the application scope of the protective cover, and improves the practicability of the protective cover.
