Description

Technical Field

[0001] This utility model belongs to the field of roller slider technology, and particularly relates to a roller slider for a linear guide rail with adjustable clearance and high stability. Background Technology

[0002] The slider is a crucial component in a mold, capable of sliding along a direction perpendicular to or at an angle to the mold opening / closing direction during the mold opening process. However, most sliders on the market currently have fixed dimensions, and as the rollers wear down over time, the gap between the slider and the guide rail gradually increases. This increased gap can cause vibration problems, thus adversely affecting the slider's performance.

[0003] Traditionally, adjusting this clearance usually requires replacing rollers with rollers of different diameters. This process not only necessitates separating the slider from the guide rail but also further disassembling the removed slider to install new rollers or rollers of the appropriate diameter. This series of operations is not only cumbersome but can also adversely affect the subsequent normal operation and performance of the slider.

[0004] Therefore, it is essential to invent a linear guide roller slider with adjustable clearance and high stability. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a high-stability linear guide roller slider with adjustable gap, including a self-adjusting gap slider body, a dustproof sealing cover, a sliding end cap assembly, an oil scraper, a roller groove, a roller return device, and rollers. A dustproof sealing cover is installed on the top of the self-adjusting gap slider body, and sliding end cap assemblies are respectively assembled at both ends of the self-adjusting gap slider body. An oil scraper is installed on the outside of the sliding end cap assembly. The self-adjusting gap slider body and the dustproof sealing cover are provided with roller grooves, and a roller return device is assembled in the roller grooves. The roller return device is used to confine the rollers within the roller grooves of the self-adjusting gap slider body and the dustproof sealing cover.

[0006] Preferably, the sliding end cap assembly is composed of two independent and slidably sealed end blocks. Each end block is fixed to the outer end of the slider body corresponding to the self-adjusting slider body, and each end block is fixedly installed with an oil scraper on its exterior. The oil scraper is in close contact with the side and upper surface of the guide rail.

[0007] Preferably, the spacing self-adjusting slider body includes a slider body, a sliding sealing plate, and adjustment holes. There are two slider bodies, and each slider body has a sliding sealing plate on its inner side. The sliding sealing plates on the two slider bodies are mutually sealed and slidably connected. The two ends of the dustproof sealing cover are respectively fixed to the upper surfaces of the two slider bodies. Each slider body has a number of adjustment holes arranged horizontally through it.

[0008] Preferably, each of the adjustment holes is fitted with a clearance bolt via thread engagement, one end of the clearance bolt is rotatably mounted with a bearing plate, and both ends of the tension spring are respectively fixed to the two bearing plates.

[0009] Preferably, the tension spring is arranged laterally above the two slider bodies, that is, above the sliding sealing plate, and below the dustproof sealing cover.

[0010] Preferably, the cross-section of the dustproof sealing cover is corrugated, and the dustproof sealing cover is allowed to extend and retract in accordance with the movement of the two slider bodies.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This invention, through its innovative self-adjusting slider body design, achieves automatic adjustment of the slider gap, effectively addressing the problem of increased gap caused by long-term roller wear. It eliminates the need for traditional, cumbersome roller disassembly and replacement procedures; only periodic inspection and adjustment of the gap bolts are required for automatic gap compensation, significantly simplifying maintenance and reducing maintenance costs and time. Simultaneously, the ingenious design of the sliding sealing plate and dustproof sealing cover not only effectively prevents the intrusion of dust and impurities, maintaining the cleanliness and lubrication of the roller groove, but also further enhances the sealing effect through the telescopic movement of the corrugated dustproof sealing cover, thereby greatly improving the stability and service life of the slider.

[0020] As attached Figure 1 To be continued Figure 3 As shown:

[0021] This utility model provides a high-stability linear guide roller slider with adjustable gap, comprising a self-adjusting gap slider body 1, a dustproof sealing cover 2, a sliding end cap assembly 3, an oil scraper 4, a roller groove 5, a roller return device 6, and rollers 7. The dustproof sealing cover 2 is installed on the top of the self-adjusting gap slider body 1. The sliding end cap assembly 3 is respectively assembled at both ends of the self-adjusting gap slider body 1, and the oil scraper 4 is assembled on the outside of the sliding end cap assembly 3. The self-adjusting gap slider body 1 and the dustproof sealing cover 2 are provided with roller grooves 5. The roller return device 6 is assembled in the roller grooves 5, and the roller return device 6 is used to restrict the rollers 7 within the roller grooves 5 of the self-adjusting gap slider body 1 and the dustproof sealing cover 2.

[0022] Furthermore, the sliding end cap assembly 3 consists of two independent end blocks that are slidably and sealingly connected to each other. These two end blocks are fixed to the outer ends of the two slider bodies 11 in the pitch self-adjusting slider body 1, and the two end blocks move with the slider bodies 11. An oil scraper 4 is fixedly installed on the outside of each end block. These oil scrapers 4 are in close contact with the side and top surfaces of the guide rail, and serve to scrape the lubricating oil.

[0023] Furthermore, the self-adjusting slider body 1 includes a slider body 11, a sliding sealing plate 12, and adjustment holes 13. Two slider bodies 11 are provided, each with a sliding sealing plate 12 on its inner side, and these two sliding sealing plates 12 are mutually sealingly and slidably connected. The dustproof sealing cover 2 is fixed at both ends to the upper surfaces of the two slider bodies 11. Several adjustment holes 13 are transversely arranged on each slider body 11 for installing gap bolts 14.

[0024] Furthermore, each adjusting hole 13 is fitted with a clearance bolt 14 via threaded engagement. One end of the clearance bolt 14 is rotatably mounted to a bearing plate 15. A tension spring 16 is laterally arranged above the two slider bodies 11, specifically above the sliding sealing plate 12 and below the dustproof sealing cover 2. Both ends of the tension spring 16 are fixed to the two bearing plates 15, serving to adjust the tension of the tension spring 16 and maintain the stability of the slider clearance.

[0025] Furthermore, the dustproof sealing cover 2 has a corrugated cross-section, which allows it to extend and retract in sync with the movement of the two slider bodies 11. This not only effectively prevents dust and impurities from entering the slider, but also maintains the flexibility and stability of the slider assembly.

[0026] The working principle is as follows: First, when the adjustable height stable linear guide roller slider of this utility model is installed on the guide rail of the mold or mechanical device, the corrugated surface design of the dustproof sealing cover 2 allows it to move in extension and retraction following the movement of the two slider bodies 11, thereby effectively preventing dust and impurities from entering the slider and keeping the roller groove 5 clean and lubricated.

[0027] Secondly, during the movement of the slider, the roller 7 rolls within the roller groove 5, and the roller return device 6 ensures that the roller 7 remains within the roller groove 5 at all times, preventing the roller 7 from falling off or becoming misaligned. At the same time, the oil scraper 4 is in close contact with the side and top surfaces of the guide rail, scraping the lubricating oil on the guide rail to ensure that the roller 7 receives uniform and appropriate lubrication, reducing friction and wear.

[0028] When the roller 7 wears down due to long-term use, causing the gap between the slider and the guide rail to gradually increase, the automatic adjustment mechanism of this invention begins to function. Specifically, the user can adjust the length of the gap bolt 14 extending into the slider body 11 by rotating it, thereby changing the relative position between the two slider bodies 11. Since the two ends of the tension spring 16 are fixed to the two bearing plates 15 respectively, and the bearing plates 15 are rotatably connected to the gap bolt 14, adjusting the gap bolt 14 will cause the tension spring 16 to stretch or compress, thereby achieving precise adjustment of the slider gap.

[0029] During adjustment, the tension spring 16 not only provides the necessary adjustment force but also ensures the stability of the slider clearance after adjustment. By properly adjusting the cooperation between the clearance bolt 14 and the tension spring 16, users can easily adjust the slider clearance to the optimal state, ensuring smooth operation and high-precision positioning of the slider on the guide rail.

[0030] Any technical solution that achieves the above-mentioned technical effects by utilizing the technical solution described in this utility model, or by designing a similar technical solution inspired by the technical solution described in this utility model, falls within the protection scope of this utility model.
