Description

Technical Field

[0001] The utility model relates to the technical field of linear guide rails, and specifically relates to an embedded linear slide rail slider device. Background Art

[0002] Linear guide rails, also known as linear guideways, slide rails, linear guide rails, and linear slide rails, can be divided into three types: roller linear guide rails, cylindrical linear guide rails, and ball linear guide rails. Linear guide rails are used in high-precision or high-speed linear reciprocating motion occasions, and can bear a certain torque, and can achieve high-precision linear motion under high load.

[0003] At present, the oil scraping piece of the linear guide rail is directly fixed by screws, lacking an external limiting structure. After long-term use and wear, it is prone to sliding, resulting in a shortened service life of the guide rail. Moreover, the buckling grooves of the existing linear guide rail cage are short and the buckling groove method is single, resulting in insufficient stability of the ball limit, and further affecting the long-term stable and smooth rotation of the ball.

[0009] Through the above technical solution, the cage limits the balls to prevent the balls from slipping out of the inside of the slider.

[0010] Preferably, a limiting groove is formed on one side of the connecting frame close to the pressing piece. The pressing piece and the oil scraping piece are arranged inside the limiting groove from inside to outside, and the shape of the limiting groove is the same as the outer contour shape of the pressing piece and the oil scraping piece.

[0011] Through the above technical solution, the pressing piece and the oil scraping piece are limited by the limiting groove, preventing the pressing piece and the oil scraping piece from shaking after long-term use and extending the service life.

[0012] Preferably, an oil scraping portion is arranged inside the oil scraping piece, and the outer end of the oil scraping portion is attached to the inner wall of the inner groove.

[0017] For this embedded linear slide rail slider, the balls are clamped and limited between the slide rail, the slider and the limiting wheel. The slider moves on the slide rail through the balls. The balls are limited by the cage to prevent the balls from slipping out of the inner side of the slider. The pressing piece and the oil scraping piece are limited by the limiting groove to prevent the pressing piece and the oil scraping piece from shaking after long-term use and extend the service life. When the slider moves on the slide rail, the oil scraping piece scrapes off the oil stains in the first buckling groove. The length of the first buckling groove is increased compared with the existing structure length, and through the cooperation of the second buckling groove, the limiting of the balls is more stable and smooth.
