Description

Technical Field

[0001] The utility model relates to the technical field of guide rail protection, in particular to a novel guide rail protection cover for a numerically controlled machine tool. Background Art

[0002] The new CNC machine tool guide rail protective cover is used to protect machine tool equipment. It can protect the machine tool's guide rails, screws, etc. from external corrosion and damage. There are many types, such as accordion protective covers and steel plate protective covers. These two are used on guide rails. There are also screw protective covers used on screws, including round, square, and polygonal. These types have different methods. There are wire support types and stitching types, as well as roller shutter protective covers and armor protective covers.

[0003] However, it still has some disadvantages. For example, the size of the new CNC machine tool guide rail protective cover cannot be freely adjusted according to the length of the guide rail. When in use, the models of machine tool guide rails are different and their lengths will vary. As a result, when the guide rail is too long, the guide rail protective cover cannot completely cover the guide rail, so that the protective cover cannot effectively protect the guide rail. When the guide rail is too short, the two ends of the protective cover will extend out of the guide rail, thereby occupying excess space. The new CNC machine tool guide rail protective cover is generally made of metal. When it is sleeved on the guide rail, friction is easily generated between the protective cover and the guide rail, thereby causing wear of the guide rail, so that the service life of the machine tool guide rail is reduced.

[0004] In order to solve the above problems, a novel CNC machine tool guide rail protective cover is proposed in the present application. Utility Model Content

[0005] The purpose of the utility model is to provide a novel CNC machine tool guide rail protective cover to solve the problems in the prior art proposed in the above background technology that the machine tool guide rail protective cover cannot adjust the length and the machine tool guide rail protective cover is easy to cause guide rail wear during installation.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a novel CNC machine tool guide rail protective cover, comprising an outer protective cover, an inner surface of one side of the outer protective cover is movably sleeved with an inner protective cover.

[0010] Preferably, a vertical fixing frame is fixedly connected to the outer surface of the left end of the second spring telescopic rod, and a second rotating slide cylinder is fixedly connected to the inner surface of the upper end of the vertical fixing frame.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model cooperates with the first rotating slide and the second rotating slide by setting, and the height of the L-shaped bracket can be changed by pulling the fixing bolt, so that the first rotating slide and the second rotating slide can be fitted on the upper outer surface and the outer surfaces on both sides of the machine tool guide rail, so that the novel CNC machine tool guide rail protective cover can be freely adjusted according to the width of the machine tool guide rail. During installation, the first rotating slide and the second rotating slide can be respectively slid on the upper outer surface and the outer surface on one side of the machine tool guide rail, which fully reduces the friction resistance between the machine tool guide rail protective cover and the machine tool guide rail, avoids wear of the guide rail when installing the protective cover, and effectively improves the service life of the machine tool guide rail.

[0016] The utility model cooperates with the outer fixing strip and the inner telescopic strip by setting the outer fixing strip, and the inner telescopic strip can be freely pulled on the inner surface of one side of the outer fixing strip by pulling the limit bolt outward, thereby driving the inner protective cover to freely telescope inside the outer protective cover, so that the new CNC machine tool guide rail protective cover can be adjusted in length according to the size of the machine tool guide rail, avoiding the guide rail protective cover being unable to fully protect the machine tool guide rail due to the difference in length of the different machine tool guide rail models, and effectively improving the practicality of the guide rail protective cover.
