Description

Technical Field

[0001] This utility model relates to the field of roller slider technology, and in particular to a roller slider with adjustable tension. Background Technology

[0002] Linear guides are important mechanical components widely used in precision machinery, automation industry, semiconductor industry, medical equipment, aerospace industry, etc. The main function of linear guides is to reduce the frictional resistance when the mechanism moves by using rollers or the rolling of rollers. However, after long-term use, the running precision between the slider and the guide rail of existing roller sliders will decrease, and the roller sliders are not easy for operators to adjust, thus affecting the normal operation of the equipment. To address this, we propose a roller slider with adjustable tension. Utility Model Content

[0003] To address the aforementioned problems, this invention provides a roller slider with adjustable tension. This invention solves the issues of existing roller sliders where the running precision between the slider and the guide rail decreases after prolonged use, and where roller sliders are inconvenient for operators to adjust, thus affecting the normal operation of the equipment.

[0004] This utility model discloses an adjustable roller slider, comprising a slider housing, with L-shaped movable plates on both sides inside the slider housing. Threaded rods are inserted into both ends of the slider housing, and the threaded rods are movably connected to the L-shaped movable plates on one side inside the slider housing. A mounting plate is provided on the side of the L-shaped movable plate away from the slider housing, and a slide bar is provided on the side of the mounting plate away from the L-shaped movable plate. Mounting grooves are provided on both side walls of the slide bar, and rollers are installed in the mounting grooves. The mounting plate and the L-shaped movable plate are fixedly connected by bolts.

[0005] In the above scheme, the L-shaped movable plate is provided with a plurality of positioning rods arranged in a matrix on the side near the slider housing, and the slider housing is provided with positioning grooves that match the positioning rods. The positioning rods are fixedly connected to the inner wall of the positioning grooves by springs.

[0006] In the above scheme, the end of the threaded rod away from the L-shaped movable plate is fixedly connected to the threaded head.

[0007] In the above scheme, the screw head is provided with an internal hexagonal groove.

[0008] In the above scheme, end caps are provided on both sides of the slider housing, and a dustproof scraper is provided on the side of the end cap away from the slider housing.

[0009] In the above scheme, the slider housing is provided with a plurality of mounting holes arranged in a matrix.

[0010] The advantages and beneficial effects of this utility model are as follows: This utility model provides a roller slider with adjustable tension. The screw head drives the threaded rod to rotate. When the threaded rod rotates, it pushes the L-shaped movable plate to move horizontally. By adjusting the position of the L-shaped movable plate, the distance between the two slide bars also changes. By adjusting the distance between the two slide bars, the accuracy of the roller slider can be adjusted. At the same time, the positioning rod is inserted into the positioning groove. Through the cooperation between the positioning rod and the positioning groove, the stability of the movement of the L-shaped movable plate is effectively ensured. This roller slider has a simple structure, and the distance between the slide bars is easy to adjust. While ensuring the normal operation of the equipment, it also effectively ensures the accuracy of the movement between the roller slider and the guide rail. Attached Figure Description

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0020] like Figure 1-3As shown, this utility model is a roller slider with adjustable tension, including a slider housing 1. L-shaped movable plates 2 are provided on both sides of the slider housing 1. Threaded rods 3 are inserted into both ends of the slider housing 1. The threaded rods 3 are located on one side of the slider housing 1 and are movably connected to the L-shaped movable plates 2. The threaded rods 3 are threadedly connected to the slider housing 1. When the threaded rods 3 are rotated, they can push the L-shaped movable plates 2 to move horizontally. By adjusting the position of the L-shaped movable plates 2, the distance between the two slider strips 5 also changes. A mounting plate 4 is provided on the side of the L-shaped movable plates 2 away from the slider housing 1. Slider strips 5 are provided on the side of the mounting plate 4 away from the L-shaped movable plates 2. Mounting grooves 6 are provided on both side walls of the slider strips 5. Rollers 7 are provided in the mounting grooves 6, and the two ends of the rollers 7 are movably connected to the side walls of the mounting grooves 6. The mounting plate 4 and the L-shaped movable plates 2 are fixedly connected by bolts 11.

[0021] The L-shaped movable plate 2 has multiple positioning rods 8 arranged in a matrix on the side near the slider housing 1. The slider housing 1 has positioning grooves 9 that match the positioning rods 8. The positioning rods 8 are fixedly connected to the inner wall of the positioning grooves 9 by springs 10. The positioning rods 8 are inserted into the positioning grooves 9. Through the cooperation between the positioning rods 8 and the positioning grooves 9, the stability of the movement of the L-shaped movable plate 2 is effectively guaranteed.

[0022] The threaded rod 3 is fixedly connected to the screw head 12 at the end away from the L-shaped movable plate 2. The screw head 12 makes it easier for the operator to rotate the threaded rod 3.

[0023] The screw head 12 has an internal hexagonal countersunk groove 13.
