Problems solved by technology

[0002] There are many types of existing linear guide rails with different structures; the linear optical axis guide rail SBR is composed of a guide rail body and a slider. The guide rail body is composed of a circular rail and an inverted T-shaped bracket. The block has a ball slider and a wear-resistant sleeve; the rolling body of the ball slider is a ball ball, the contact area between the ball ball and the round rail is relatively small, and the friction coefficient between the round rail and the slider is small. The problem is that the force is small and it is easy to cause vibration, so it is only suitable for use in places with small loads; the friction coefficient between the circular rail and the slider of the wear-resistant sleeve slider is large, it is easy to wear, and the accuracy is difficult to control ; Therefore, the development of a new type of linear guide has become an urgent need

Abstract

The invention relates to the technical field of guide rails, and discloses a linear guide rail which comprises a guide rail body and a sliding block. The guide rail body is composed of a circular rail and an inverted-T-shaped support, the guide rail body is sleeved with the sliding block, and the sliding block comprises a sliding block body. Limiting grooves are formed in the front face and the rear face of the sliding block body correspondingly. Snap spring grooves are formed in the limiting grooves. Limiting pads are arranged on the limiting grooves. Snap springs are arranged on the snap spring grooves. A groove is formed in the inner end face of each limiting groove in the length direction. A dodging groove is formed in the bottom edge of each groove. Ball grooves are formed in the grooves. Rollers are arranged in the ball grooves. During use, the arcs in the rollers make contact with the cylindrical surface of the circular rail, and the contact area is large; and the sliding block body can be machined through a linear cutting machine tool, the guide rail body can be a chromium-plated rod sold in the market, and therefore labor and time are saved, and the linear guide rail has the advantages of being high in rigidity, easy to machine and produce and the like.
