Description
Technical Field
[0001] This utility model relates to the field of guide rail sliders, specifically a high-precision self-lubricating guide rail slider structure. Background Technology
[0002] In modern industrial automation and precision manufacturing, linear guide slider structures serve as crucial transmission components, directly impacting the positioning accuracy, operational stability, and service life of equipment. With advancements in technology and the development of the manufacturing industry, higher demands are being placed on the precision, reliability, and ease of maintenance of linear guide slider structures.
[0003] Traditional linear guide slider structures typically rely on external lubrication systems to reduce friction and wear, ensuring proper operation. However, this lubrication method has several drawbacks. First, external lubrication systems require regular maintenance and replenishment of lubricating oil, increasing equipment maintenance costs and workload. Utility Model Content
[0004] The purpose of this invention is to provide a high-precision self-lubricating guide rail slider structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A high-precision self-lubricating guide rail slider structure includes a slide rail block, which further includes a slide groove block and side groove blocks. There are two sets of side groove blocks, and the two sets of side groove blocks are fixedly connected to both ends of the slide groove block. The inner wall of the side groove block is provided with a guide groove, and a ball is installed at the groove opening. The inner side of the side groove block and the inner side of the slide groove block are both fixedly connected with protruding rails. Threaded holes are provided on both the left and right sides of the upper surface of the slide groove block.
[0007] As a further embodiment of this utility model: the inner cavity of the slide block is hollow on both the left and right sides, and an isolation plate is installed at the end of the inner cavity of the slide block near the guide groove.
[0008] As a further improvement of this utility model: the front and rear surfaces of the isolation plate are provided with perforations, and a sphere is provided at the perforation, and the sphere is in contact with the perforation.
[0009] As a further improvement of this utility model, bolts are installed on the left and right sides of the outer ends of the two sets of side groove blocks.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] In this utility model, a side groove block is fixed on the outer wall of the slide block to assemble it into a whole slide rail block. A threaded hole on the top of the slide rail block is used to introduce lubricant into the inner cavity of the slide rail block. The lubricant lubricates the guide groove. The lubricant is introduced into the outer wall of the ball through the perforation in the guide groove for lubrication. The guide groove on the inner side of the slide block is used to place the ball. At the same time, the guide grooves locked at both ends of the ball are used to cooperate with the slide rail for sliding. Its structure is more optimized and its design is more reasonable.

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Please see Figures 1-4 In this embodiment of the utility model, a high-precision self-lubricating guide rail slider structure includes a slide rail block 1, which further includes a slide groove block 3 and a side groove block 5. There are two sets of side groove blocks 5, which are fixedly connected to both ends of the slide groove block 3. The inner wall of the side groove block 5 is provided with a guide groove 9, and a ball 4 is installed at the groove opening of the guide groove 9. The inner side of the side groove block 5 and the inner side of the slide groove block 3 are both fixedly connected with a protruding rail 7. Threaded holes 8 are provided on both the left and right sides of the upper surface of the slide groove block 3.
[0019] The inner cavity of the slide block 3 is hollow on both the left and right sides, and an isolation plate is installed at the end of the inner cavity of the slide block 3 near the guide groove 9.
[0020] The front and rear surfaces of the isolation plate are perforated, and a ball 4 is provided at the perforation, and the ball 4 is in contact with the perforation.
[0021] Bolts 2 are installed on the left and right sides of the outer end of both sets of side groove blocks 5.
[0022] The working principle of this utility model is as follows:
[0023] In use, the fixed side groove block 5 on the outer wall of the slide block 3 is used to assemble the slide rail block 1 into a whole. The threaded hole 8 on the top of the slide rail block 1 is used to introduce lubricant into the inner cavity of the slide rail block 1. The lubricant lubricates the guide groove 9. Specifically, the lubricant is introduced into the outer wall of the ball 4 through the through hole 10 opened in the guide groove 9 for lubrication.
