Technical Field

[0001] This invention relates to a linear motion functional component, and more particularly to a linear guide slider. Background Technology

[0002] Linear guide pairs typically consist of a guide rail, a slider, a return mechanism, and steel balls. The slider and return mechanism are generally connected by threads, and then steel balls are installed to match the guide rail. To install the return mechanism, threaded holes and return ball holes are usually machined at both ends of the slider, significantly increasing the difficulty of the manufacturing process and resulting in high product costs. Summary of the Invention

[0004] A linear guide slider according to a first aspect of the present invention includes a slider body, the slider body being generally concave, and U-shaped channels for accommodating steel balls being provided on the inner and outer sides and the front and rear ends of the protruding portion of the slider body. A return belt is provided on the outer side of the protruding portion of the slider body, and the return belt and the U-shaped channels constitute a ball return channel for the steel balls.

[0005] According to some embodiments of the present invention, the return belt is generally C-shaped.

[0006] According to some embodiments of the present invention, the return belt is formed by stamping metal material.

[0007] According to some embodiments of the present invention, the return belt is injection molded.

[0008] According to some embodiments of the present invention, the slider body is provided with a slot, and the return belt is engaged with the slider body through the slot.

[0009] According to some embodiments of the present invention, the outer side and the front and rear ends of the protruding portion of the slider body are designed with slots for mounting the return belt.

[0010] According to some embodiments of the present invention, the slot is disposed on the upper and lower positions of the outer side of the protruding portion of the slider body and on the upper and lower positions of the front and rear ends.

[0011] According to some embodiments of the present invention, the slider body is integrally manufactured by powder metallurgy.

[0012] According to some embodiments of the present invention, the cross-section of the U-shaped channel is semi-circular.

[0013] According to some embodiments of the present invention, the return belt is flush with the outer surface of the slider body after installation.

[0014] According to an embodiment of the present invention, a linear guide slider has at least the following advantages: the product directly snaps the return belt onto the slider body, thereby eliminating the need for mounting threaded holes. In addition, after the return belt is installed, it forms a ball return channel with the slider body, which also eliminates the need for ball return hole machining, thereby making the product manufacturing process simpler and the cost lower.

[0015] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0021] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, etc., are based on the orientation or positional relationship shown in the drawings and are only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0023] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0024] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0025] Reference Figure 1 A linear guide slider includes a slider body 1, which is generally concave. U-shaped channels 11 for accommodating steel balls 2 are provided on the inner and outer sides and the front and rear ends of the protruding portion of the slider body 1. The cross-section of the U-shaped channels 11 is semi-circular. A return band 3 is installed on the outer side of the protruding portion of the slider body 1, and the return band 3 and the U-shaped channels 11 constitute a ball return channel for the steel balls 2.

[0026] Reference Figure 2 , Figure 3 The slider body 1 is provided with a slot 12, and the return belt 3 is snapped onto the slider body 1 through the slot 12. In order to make the installation more secure, the outer side of the protruding part of the slider body 1 and the front and rear ends are designed with slots 12 for installing the return belt 3. At the same time, the slots 12 are located at the upper and lower positions of the outer side of the protruding part of the slider body 1 and at the upper and lower positions of the front and rear ends. Of course, other snap-fit ​​installation methods can also be used for installation according to actual needs.

[0027] Reference Figure 4 The return belt 3 is C-shaped in general. In addition, the return belt 3 is made of metal material by stamping. Compared with ordinary plastic return devices, the mold cost is lower and the dimensional accuracy is easier to guarantee. It is best to use stainless steel material for stamping. This design has better high temperature resistance and corrosion resistance than plastic return devices and is more suitable for special applications. Of course, the return belt 3 can also be made by injection molding.

[0028] The slider body 1 can be manufactured using processes such as electrical discharge machining, powder metallurgy, and wire cutting, which makes it easier to ensure dimensional accuracy.

[0029] In addition, the return belt 3 is flush with the outer surface of the slider body 1 after installation, which makes the product more aesthetically pleasing.

[0030] This product directly attaches the return belt 3 to the slider body 1, thus eliminating the need for mounting threaded holes. In addition, after installation, the return belt 3 and the slider body 1 form a ball return channel for the steel balls, eliminating the need for ball return hole machining. This makes the product manufacturing process simpler and the cost lower.

[0031] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
