Technical Field
[0001] This utility model relates to the field of linear guide technology, and in particular to a single-row ball slider guide device. Background Technology
[0002] Linear guides are mechanical components used to achieve high-precision linear motion. They are indispensable core components in modern industry, with applications covering almost all fields requiring precise positioning, stable support, and efficient linear transmission, such as CNC machine tools, automated assembly lines, robotic arms, medical equipment, precision testing equipment, pick-and-place machines, lithography machines, and electronics and semiconductor manufacturing. Linear guides provide crucial support for efficient and reliable production and research and development. They can be used for heavy-duty material handling and precise positioning in horizontal space, as well as precise guiding motion in vertical space.
[0003] Linear guides are widely used in various industries due to their high-speed, high-precision, and repetitive reciprocating operation. Now, some small mechanical equipment and applications with low load also require linear guides. Existing linear guides are used in small automated mechanical equipment, small precision instruments, small transmission mechanisms, small assembly lines, and other applications with low load. In these mechanical equipment, small-sized linear guides are required within the available space. While the size of the linear guide is reduced, the number of processing steps does not decrease. The processing and assembly difficulty of the reduced-size guide also increases. Therefore, it is necessary to develop a single-row ball-slider guide device to solve the above-mentioned technical problems. Utility Model Content
[0004] The purpose of this invention is to address the technical problem of using existing linear guides in small-scale automated machinery, small precision instruments, small transmission mechanisms, small assembly lines, and other applications with relatively small loads. These machines require small-sized linear guides within their limited space. While the size of the linear guides is reduced, the number of processing steps does not decrease, and the processing and assembly difficulties of the smaller guides also increase. Therefore, a single-row ball-slider guide device is needed to solve the above-mentioned technical problems.

The Y-shaped groove is divided into a ball sliding groove and an anti-interference groove. The bottom of the single slider is provided with a row of ball grooves. The balls are assembled in the ball grooves by the ball retainer. The ball retainer is composed of a ball limiting frame and a ball anti-drop frame. The end caps are assembled at both ends of the single slider along the axial direction. The sealing dustproof sheet is assembled at the outermost ends of both ends of the single slider along the axial direction. The bottom of both the end caps and the sealing dustproof sheet is provided with an arc-shaped protrusion. The axial ends of the ball retainer are provided with protrusions, and the protrusions have the same appearance shape as the arc-shaped protrusions.
[0006] Furthermore, the Y-shaped groove has one row, and the ball sliding groove has two rows. The ball sliding groove is an inclined groove, and the two rows of ball sliding grooves are located on the upper sides of the anti-interference groove, respectively.
[0007] Furthermore, the ball retainer is an integral structure and is made of plastic.
[0008] Furthermore, the sealing dustproof sheet is a metal sealing dustproof sheet.
[0009] Furthermore, the end cap is a plastic part.
[0010] Furthermore, the single guide rail has mounting through holes on its side, and the single slider has mounting holes on its top and side.
