Linear sliding rail structure capable of being modularized

Abstract

The invention discloses a linear sliding rail structure capable of being modularized. The linear sliding rail comprises a sliding rail unit, a sliding block unit and a driving unit. The sliding rail unit is provided with a sliding rail base extending in the long axis direction and two slideway seats, the slideway seats are assembled on the two sides of the sliding rail base, and a sliding groove is formed by the slideway seats and the sliding rail base. The sliding block unit is arranged on the sliding groove in a sliding fit manner and is provided with a sliding block base, two backflow assemblies arranged on the two sides of the sliding block base and a nut arranged in the sliding block base. The driving unit is provided with a screw rod capable of being driven by external power to rotate, and the screw rod extends in the long axis direction to penetrate through the sliding block unit and is combined with the nut. Through the arrangement manner of the combined slideway seats, the ball assembly structure of the sliding block unit and the nut hidden in the middle of the sliding block base, the linear sliding rail achieves the use aims in rigidity, precision and space application atthe same time.

Description

technical field [0001] The present invention relates to a linear slide rail, in particular to a modular linear slide rail structure with simple assembly, high rigidity and space saving. Background technique [0002] The structure of the existing linear slide rail includes a slide rail body extending along an axial direction, a slider body combined with the slide rail body, and a screw rod extending along the axial direction and passing through the center of the slider body , and a nut combined with the screw rod, through the combination relationship between the nut and the screw rod, the main body of the slider used for loading can be moved by the screw rod, and move back and forth smoothly along the axial direction. [0003] However, in order to achieve a certain rigidity in the existing first type of linear slide rail, the slide rail main body of the linear slide rail and the nut are assembled together, but this combination takes up more space, which also leads to One of ...

Problems solved by technology

[0003] However, in order to achieve a certain rigidity in the existing first type of linear slide rail, the slide rail main body of the linear slide rail and the nut are assembled together, but this combination takes up more space, which also leads to One of the reasons why the entire linear slide is bulky

[0004] Secondly, there is the second type of linear slide rail. The main body of the slide rail adopts a U-shaped track structure. The overall requirement is high rigidity. The main body of the slider and the nut are designed in one piece, which also has the effect of saving space. However, although this type of linear slide rail can withstand high loads, it results in a heavier overall weight.

[0005] In addition, there is a third type of linear slide rail. In order to improve the insufficient rigidity of the existing aluminum alloy slider, steel bars are installed in the main body of the U-shaped aluminum alloy rail in order to achieve the appeal of light weight. However, this light weight The linear slide rail is a low-load type of miniature linear slide rail, and it cannot be widely used in various heavy-duty linear slide rails.

[0006] Therefore, among the above-mentioned existing types of linear slide rails, either they can only be applied to light-weight and low-load linear slide rails, and the overall weight is relatively heavy, or they cannot have both rigidity, precision, and space utilization at the same time. Therefore, , linear slides with high rigidity, high precision and good space utilization have always been one of the goals pursued by the linear slide industry, so it is necessary to find a solution
