Description

Linear slide with dustproof element

The invention relates to a linear slide rail device, in particular to a dustproof structure on a slider of a linear slide rail, which can use the flexible lip to scrape off the oil stain on the upper surface of the slide rail at any time and prevent foreign matter from entering from the upper surface of the slide rail. Rows of steel ball grooves for better dust protection and linear slide life.

Due to the increasing use of linear transmission components in modern industries, various linear transmission components have been widely used in human life, processing plants and high-tech equipment, such as linear slides, ball screws, etc.; In general, large-scale precision machines are equipped with different linear slide systems of various sizes. Although the development of linear transmission components technology is very rapid, consumer users still need continuous improvement of technology, and thus many problems still to be developed. In particular, in many fields of high-precision manufacturing and industrial machinery that require more stable and quiet, there are more and more sounds of R&D and improvement. Therefore, some technical blind spots of linear transmission components are urgently needed to be developed and improved.

At present, in order to prevent the dust or oil on the upper surface of the slide rail from entering the rolling element in the slider, the manufacturer usually installs a dustproof structure on the upper side of the inner wall of the slider of the linear slide rail corresponding to the upper row of the steel ball groove. The common dustproof structure is the invention of the invention of U.S. Patent No. 4,918,846, which is shown in Fig. 5, which has a dust-proof U-shaped metal plate (10) at the end of the slider, and the U-shaped metal plate (10) uses spring steel. Stamping and forming, and then fixing the lip (11) of the dust-proof piece to the edge of the metal plate (10) (the fixing method can be used for positioning), and the locking method between the metal plate (10) and the slider is divided into two parts. One of them is to drill holes in the slider body for positioning the metal plate (10) to the upper locking screw, and the other part is to fix the fixing position of the nozzle member at the outer end of the slider. This application uses the lip of the dustproof piece (11) Blocking the dust or oil on the upper surface of the slide rail; however, after the application, the dustproof structure is locked by using a plurality of screws, and some of the nozzles need to be matched with the locking metal plate (10), and the assembly procedure is complicated, and the manufacture thereof is complicated. The cost is quite high and does not meet the economic benefits. Therefore, it is necessary to improve and improve.

In view of the above problems, the main object of the present invention is to develop an upper dustproof component that is highly versatile and does not require screw locking.

In order to achieve the above object, the present invention is a linear slide rail with a dustproof member, comprising: a rail extending in a direction into a strip-like structure, the extension direction being defined as an axial direction, the rail being on the shaft A plurality of rolling grooves and a fixing convex portion are respectively disposed on two sides of the direction; a slider module is sleeved on the rail and reciprocally movable relative to the rail, the slider module has an upper top surface And an engaging groove extending from both sides of the upper surface of the upper surface; an upper dustproof member having a body matching the upper surface, and an engaging portion extending from the main body toward the axial direction, the engaging portion The engaging portion is embedded in the engaging groove, and the engaging portion has a contact end portion which is in contact with the fixing convex portion, and the body corresponding to the upper surface of the rail bar is provided with two dust-proof lips disposed at a distance and a distance. The end of the dust lip is in contact with the upper surface.

Preferably, the fixing convex portion has a U-shape, and the engaging groove and the engaging portion are substantially C-shaped.

Preferably, the slider module has a slider body, a plurality of rolling members, two end covers and an end dustproof piece. The slider body has a plurality of rolling grooves corresponding to the rolling grooves, and the rolling groove and the rolling groove system are configured. a load path, a plurality of the rolling members are disposed on the load path, and the end caps are respectively disposed on both end faces of the slider body in the axial direction, the end cover provides a plurality of rolling elements to recirculate, and the end dustproof film is The end cover is disposed, and the end dustproof piece is provided with a lip that is in contact with the surface of the rail.

Preferably, the engaging portion extends toward the two end pieces of the dustproof piece and is in contact with the end dustproof piece.

According to the mutual matching of the above technical features, the upper dustproof component can be fixed to the slider module by the cooperation between the engaging portion and the engaging groove, and the dust lip portion and the contact end portion are The setting provides two paths to prevent foreign matter from entering the rolling element, ensuring smooth operation of the slider module and increasing the life of the slider module.
