Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a novel stable linear guide device. Background Technology

[0002] Linear guides can be used for heavy-duty handling and precise positioning in horizontal space, as well as precise guiding in vertical space. They enable reliable movement in relatively small spaces and have wide applications in machine tools, electronics, medical devices, and robotics industries.

[0003] Linear guides primarily transmit loads through the reciprocating rolling of balls. Some high-load linear guides utilize rollers as the transmission element. Currently, the balls are assembled onto the slider. However, in existing linear guides, especially newer ones, the simple method of fixing the steel balls within the slider leads to ball loss during operation, affecting the linear guide's running accuracy. Over extended periods, ball wear or thermal deformation can also cause ball loss, further impacting the linear guide's accuracy. Therefore, a new, stable linear guide device is needed to address these technical problems. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems of existing linear guides, especially new linear guide devices, where the simple installation and fixing method of the steel balls inside the slider leads to the ball falling off during operation, affecting the running accuracy of the linear guide. Furthermore, the ball falling off due to wear or heat deformation of the ball during long-term operation also affects the running accuracy of the linear guide. Therefore, a new type of stable linear guide device is needed to solve the above-mentioned technical problems.

[0005] A novel stable linear guide device, characterized in that it comprises a linear guide, a slider, balls, a ball retainer, a ball cage, a ball retainer, an end cap, and a sealing dustproof sheet. The slider is slidably assembled on the linear guide. Grooves are provided on both sides of the upper part of the linear guide. An opening is provided at the bottom of the slider, the shape of which matches the shape of the linear guide. Arc-shaped grooves are provided on both sides of the opening, with each groove corresponding to one of the arc-shaped grooves. A ball track is provided on the axial end face of the slider, with each ball track corresponding to one of the arc-shaped grooves. The groove and ball track form a complete ball running channel. The balls are assembled in the arc groove. The ball retainer, end cap, ball retainer frame, and sealing dustproof sheet are sequentially assembled at both ends of the slider. The ball retainer has a ball guide arc and a cylindrical groove. The groove of the ball retainer is engaged in the ball track. The end cap has a groove. The ball guide arc is engaged in the groove. The ball retainer has a U-shaped opening pipe. The U-shaped opening pipe passes through the end cap and fits against the cylindrical groove. The sealing dustproof sheet is assembled on the outermost side of the slider's axial end.

[0006] Furthermore, the grooves are arranged in six rows, with three rows distributed on one side of the upper part of the linear guide rail and the other three symmetrically distributed on the other side of the upper part of the linear guide rail.

[0007] Furthermore, there are six arc-shaped grooves, three of which are distributed in one side of the slider opening, and the other three are symmetrically distributed in the other side of the slider opening.

[0008] Furthermore, the ball guide arc and cylindrical groove have four rows, the U-shaped opening pipe has four rows, and the groove has four.

[0009] Furthermore, the ball retainer, end cap, and ball retainer are all integral structures and are made of plastic.

[0010] Furthermore, the sealing dustproof sheet is a metal sealing dustproof sheet.

[0011] Compared with existing technologies, the advantages of this utility model include: the grinding wheel body is divided into a slider processing section and a cylindrical mounting section. The size and structure of the slider processing section match the slider groove to be processed. The grinding wheel body grinds the slider groove through the slider processing section. In actual use, as the grinding wheel body rotates at high speed on the machine tool spindle, the slider groove to be ground passes back and forth through the slider processing section of the grinding wheel body, thus completing the grinding of the slider groove. The groove is used to avoid processing interference. Different specifications of grinding wheels do not need to be changed during slider groove processing; the processing of the slider grooves on both sides of the inner side of the slider can be completed in one operation, resulting in high processing efficiency and efficient slider processing. The cylindrical mounting section increases the assembly length between the grinding wheel body and the machine tool spindle, allowing the grinding wheel body to be firmly fixed on the machine tool spindle. It also ensures that the slider processing section is not interfered with during slider groove processing, guaranteeing the processing accuracy of the slider groove. Attached Figure Description
