Sliding-block structure of linear roller sliding rail

Abstract

A slide structure of linear roller slideways mainly includes a main slider and a secondary slider. Each of the sliders has a holding slot and a spout. The secondary slider is held in the holding slot and on each side of the secondary slider is formed a vertical part. On the contact surface of each vertical part with the main slider are set several oblique grooves through two sides. On each side of each groove is formed a holding part, so that the roller can roll in the endless loop in the grooves between the main and the second sliders and the slideway.

Description

technical field [0001] The invention relates to a sliding block structure of a linear roller slide rail, the main purpose of which is to allow a sliding rail to pass through it, so that the rollers located in the sliding block and between the sliding block and the sliding rail can roll infinitely. When doing linear displacement, it can be smooth and smooth. Background technique [0002] Linear slides are important mechanical components and have been widely used in precision machinery, automation industry, semiconductor industry, medical equipment, aerospace industry, etc. The main function is to apply the rolling of balls or rollers To reduce the frictional resistance when the mechanism moves, so that the mechanism is more labor-saving and energy-saving when moving. At the same time, due to the reduction of friction, the wear of the contact surface and the reduction of humidity increase, the accuracy and life of the mechanism are both improved, and the moving speed of the me...

Problems solved by technology

Usually linear slides can be divided into two categories, one is the use of ball transmission, called linear ball slides; the other is the use of roller transmission, called linear roller slides; however, whether it is ball or roller slides , because the slider (slider) needs to provide rolling elements (balls or rollers) bearing and circulation backflow and other functions, so the structure is relatively complicated, and the processing procedures are also cumbersome, resulting in a relatively high cost

[0003] Please refer to Fig. 1, shown in 2, early stage roller linear slideway comprises a slide block 10 that has chute 14, and a slide rail 15 that is pivoted in chute 14; The function carried by the rollers 16, that is, several rolling grooves 141 are provided on both sides of the inner wall of the chute 14. The rolling grooves 141 are the tracks on which the rollers 16 roll, and the rolling grooves 141 need to match the side profile of the rollers 16. The cross-sections of 15 are matched to form a rectangular hole between them, and the rolling groove 141 is used to carry the load of the mechanism. In order to make the roller 16 move in the opposite direction to achieve the purpose of endless rolling, the end surface of the slider 10 must be provided with several self-supporting rollers. The side end surface is connected to the backflow hole 11 at the other side end. The backflow hole 11 needs to match the side profile of the roller 16, and its cross section needs to be made into a rectangular hole. The relative adjacent sides of the above-mentioned rolling grooves 141 and the backflow hole 11 are for installation The retaining chain 17 of the roller 16 can pass through, and an escape groove 13 and wing groove 12 need to be provided again, so that the flange 171 of the protection chain 17 can pass through; The difficulty and cost are extremely high, and it is not in line with economic benefits

[0004] Please refer to Figs. 3 and 4, which is an improvement of the above-mentioned first conventional linear roller slide rail. In the position where the slide block 10 is originally provided with return holes and wing-shaped grooves, several self-sliding blocks 10 are first drilled. The circular perforation 18 that runs through one end surface to the other end surface is filled with a plastic piece 19 that already has a rectangular backflow hole 11 and wing-shaped groove 12. The backflow hole 11 can allow the rollers 16 and the retaining chain 17 at the same time. Through the wing-shaped groove 12, the flange 171 on the chain 17 is allowed to pass through; although the second conventional linear roller slide rail overcomes the disadvantages that the backflow hole 11 and the wing-shaped groove 12 are not easy to process, this method Not only is the manufacturing process complicated, but the strength of plastic is much lower than that of steel, which reduces the structural strength of the slider 10 and does not meet the requirements of use.

[0005] Furthermore, the sliders and slide rails of the above two conventional linear roller slide rails are not independent, and the sliders and slide rails cannot be stored separately, which wastes storage space and cost
