Description

Technical Field

[0001] This utility model belongs to the field of ball block assembly technology, and in particular relates to a steel ball pressing mechanism for slide rail ball blocks. Background Technology

[0002] The ball bearing block, also known as the slider, is an important component of a linear guide rail.

[0003] Chinese Patent (CN201921332350.2) discloses a wide linear guide rail slider pair, including a slider mounted on a guide rail. The sidewall surfaces on both sides of the slider slot are symmetrically provided with longitudinally penetrating arc-shaped ball tracks. The ball tracks are concentric with the arc-shaped ball tracks on both sides of the guide rail and together form a circulation channel. The sidewalls on both sides of the slider slot are symmetrically provided with longitudinally penetrating circulation channels. End caps and oil scrapers are installed sequentially at both ends of the slider. The side of the end cap that contacts the slider is provided with symmetrically arranged rotary channels. A limit groove is provided in the middle of the inner surface of the ball track, and a limit shaft is slidably connected to the arc surface inside the limit groove.

[0004] Currently, it is necessary to manually move the limiting shaft connected to the scraper blade to prevent it from blocking the ball track before steel balls can be inserted into the ball track. This makes the installation operation inconvenient and affects the efficiency of steel ball assembly. Utility Model Content

[0005] The purpose of this utility model is to provide a steel ball pressing mechanism for a slide rail ball block in order to solve the above-mentioned problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel ball pressing mechanism for a slide rail ball block, comprising:

[0007] A ball bearing box is a rectangular, open-top box. Inside the ball bearing box are two symmetrically arranged V-shaped grooves. On each of the opposite sides of the ball bearing box are multiple slides that extend to the bottom of the corresponding V-shaped grooves. The bottom of the ball bearing box has two grooves.

[0008] A cover that snaps into the opening of the ball box, and the cover is connected to the ball box by multiple springs;

[0009] Two limiting rings are provided on opposite sides of the ball box, the two limiting rings are connected to the cover, and the two limiting rings block multiple slides.

[0010] As a further description of the above technical solution:

[0011] The multiple slides located on the same side of the ball bearing box are arranged at equal intervals along a straight line.

[0012] As a further description of the above technical solution:

[0013] The slide has a circular cross-section.

[0014] As a further description of the above technical solution:

[0015] The ball bearing box has sinking grooves on both opposite sides, and the two limiting rings are located in the two sinking grooves respectively.

[0016] As a further description of the above technical solution:

[0017] The cover has a through hole, and a plug is inserted into the through hole.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] In this invention, a large number of steel balls are loaded into the ball box. Guided by the V-groove, the steel balls slide into the slide. The steel balls at the end of the slide are blocked by the limiting ring, pressing the entire ball box into the slider. The groove hooks the limiting shaft inside the slider, causing it to move away from the ball track. Pressing down the cover causes the limiting ring to move away from the slide, and the steel balls naturally slide into the slider. After releasing the cover, the limiting ring resets under the elastic action of the spring and presses the steel balls into the slider, making the installation of the steel balls convenient and improving the assembly efficiency of the steel balls.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a technical solution: a steel ball pressing mechanism for a slide rail ball block, comprising:

[0029] The ball box 1 is a rectangular box without a lid. The ball box 1 has two symmetrically arranged V-shaped grooves 2. Multiple slides 3 are provided on both sides of the ball box 1. The slides 3 extend to the bottom of the corresponding V-shaped grooves 2. The bottom of the ball box 1 has two grooves 4.

[0030] The cover 5 is snapped into the opening of the ball box 1, and the cover 5 is connected to the ball box 1 by multiple springs 6;

[0031] Two limiting rings 7 are provided on opposite sides of the ball box 1. The two limiting rings 7 are connected to the cover 5, and the two limiting rings 7 block multiple slides 3.

[0032] The multiple slides 3 located on the same side of the ball box 1 are evenly arranged at equal intervals along a straight line;

[0033] The cross-section of the slide 3 is circular to ensure that the steel ball can slide smoothly;

[0034] The ball box 1 has a recessed groove 8 on each of its two opposite sides, and the two limiting rings 7 are respectively located in the two recessed grooves 8 to ensure that the movement of the limiting rings 7 will not interfere with the slider.

[0035] The cover 5 has a through hole 9, and a plug 10 is inserted into the through hole 9 to facilitate the addition of steel balls into the steel ball box 1.

[0036] Working principle: First, open the plug 10 and load a large number of steel balls into the ball box 1 through the through hole 9. Under the guidance of the V-groove 2, the steel balls slide into the slide 3. Second, the steel balls at the end of the slide 3 are blocked by the limiting ring 7, pressing the ball box 1 into the slider. The groove 4 hooks the limiting shaft in the slider, causing it to move away from the position of the ball track. Next, press down the cover 5 so that the limiting ring 7 moves away from the slide 3, and the steel balls naturally slide into the slider. Finally, after releasing the cover 5, the limiting ring 7 returns to its original position under the elastic action of the spring 6 and presses the steel balls into the slider.
