Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a linear guide with a quick assembly and disassembly mechanism. Background Technology

[0002] Linear guides, also known as linear slides, are mechanical components used to carry and guide loads along a specific straight line. They are widely used in precision machinery, automation equipment, robotics, CNC machine tools, and other fields, providing smooth and precise linear motion.

[0003] Currently, every time a linear guide needs to replace a slider or ball, it requires steps such as screw removal and reassembly, which increases the complexity of maintenance. The process of disassembling and replacing parts consumes a lot of time, especially when the production line or equipment requires frequent maintenance, which can lead to long downtime and affect production efficiency. Frequent disassembly and assembly of screws and sliders can not only easily lead to a decrease in the accuracy of the guide rail, but also easily lead to wear or damage to connecting parts such as screws and nuts, requiring frequent replacement, thereby increasing maintenance costs and parts consumption, and making the equipment less practical. Utility Model Content

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1 to 4A linear guide rail with a quick assembly / disassembly mechanism includes a guide rail 2, a slider 1 mounted on the guide rail 2, and two ball bearing members 22 slidably connected to the guide rail 2 via ball bearing members 22. The two ball bearing members 22 are respectively mounted on the inner wall of the slider 1 via an mounting assembly. Each ball bearing member 22 has a connecting groove, and the slider 1 has a second sliding groove 7. The connecting groove corresponds to the second sliding groove 7. The mounting assembly includes a connecting shell 10, with a third sliding groove 11 at one end. A pusher 8 is slidably connected to the third sliding groove 11. A guide plate 13 is slidably connected to the connecting shell 10. A connecting post 12 is fixedly connected to the side of the guide plate 13 closest to the pusher 8, and a connecting plate 9 is fixedly connected to the end of the connecting post 12 furthest from the guide plate 13. The connecting plate 9 is fixed to the pusher 8. The connecting plate 9 is slidably connected to the connecting shell 10. A slide rail is provided on the guide plate 13, and a cylindrical block is slidably connected to the slide rail. A rotating component 14 is rotatably connected to the cylindrical block. The end of the rotating component 14 away from the cylindrical block is rotatably connected to the connecting shell 10 via a rotating shaft, which is located on the side of the guide plate 13 away from the connecting column 12. When installing the ball bearing component 22, the pushing component 8 carries the connecting shell 10 along the inner wall of the second slide groove 7 into the connecting groove of the ball bearing component 22. Subsequently, the pushing component 8 is pushed to slide along the inner wall of the third slide groove 11 of the connecting shell 10, causing the connecting plate 9 to drive the connecting column 12 to push the guide plate 13 along the inner wall of the connecting shell 10 towards the connecting groove. As the guide plate 13 approaches the rotating shaft, the cylindrical block moves along the slide rail until the guide plate 13 approaches the connecting groove. One end of column 12 (this is prior art and will not be described further here), the top and bottom of guide plate 13 are respectively fixedly installed with connecting blocks 15, the top and bottom of connecting shell 10 are respectively provided with limiting grooves 24, the connecting blocks 15 are slidably connected with the corresponding limiting grooves 24, the side of connecting block 15 away from pusher 8 is fixedly connected with telescopic rod 16, the inside of telescopic rod 16 is provided with spring 17, the end of telescopic rod 16 away from connecting block 15 is fixedly connected with push block 18, the top and bottom of connecting shell 10 are respectively rotatably connected with locking blocks 19 through connecting shaft 21, the two locking blocks 19 correspond to the two connecting blocks 15 respectively, and are located on the side of the corresponding push block 18 away from telescopic rod 16, the side of locking block 19 near push block 18 is provided with push groove 20. The pushing groove 20 corresponds to the pushing block 18. The ball-bearing component 22 is provided with a slot 23 corresponding to the locking block 19. The guide plate 13 drives the connecting block 15 to slide along the limiting groove 24 while squeezing the telescopic rod 16, so that the pushing block 18 pushes the locking block 19 to rotate into the corresponding slot 23. This allows the installation component to complete the installation of the ball-bearing component 22 and the slider 1. The installation component replaces the screw connection, so that the installation process no longer relies on tools and screws. The operator only needs to push and slide the installation component to easily complete the installation or disassembly of the ball-bearing component 22 and the slider 1, which greatly reduces the complexity of operation and the time required. The slider 1 is fixedly installed with a fitting block 5 on both sides. The slider 1 is provided with a partition 3 on both sides. The partition 3 is provided with a first sliding groove 6.The first slide groove 6 is slidably connected to the corresponding mating block 5, and side sealing plates 4 are fixedly connected to the sides of the two partitions 3 that are far apart from each other.

[0016] In this invention, when a quick assembly / disassembly device is required, first align one side surface of the ball-bearing member 22 with the inner surface of the slider 1, aligning the connecting groove with the second sliding groove 7 to achieve through connection. Then, push the pusher 8, along with the connecting shell 10, into the second sliding groove 7. After being fully pushed in, part of the connecting shell 10 will be at the connecting groove of the ball-bearing member 22. Then, gently press the pusher 8 inward, causing it to slide inward through the third sliding groove 11 in the connecting shell 10, thereby driving the connecting plate 9 inward. The connecting plate 9 and the connecting post 12 are fixedly connected, thus causing the guide plate 13 to also move inward. The cylinder on the rotating part 14 slides along the slide rail on the guide plate 13. The connecting blocks 15 fixedly installed on both sides of the guide plate 13 slide synchronously with the guide plate 13. A limit groove 24 is opened on one side surface of the connecting shell 10 so that the connecting block 15 can slide forward smoothly. Then the connecting block 15 will push the telescopic rod 16, thereby squeezing the internal spring 17 to push forward and push the pushing block 18 into the pushing groove 20. At this time, the locking block 19 will be lifted upward with the rotation of the connecting shaft 21 due to the pushing force. At this time, the rotating part 14 reaches the rightmost end of the guide plate 13. Figure 3 (As shown in the direction), push to stop, guide plate 13 locks the rotating part 14, so that the locking block 19 is locked in the slot 23, and the ball bearing part 22 is fixed on the slider 1. Then the partition plate 3 and the slider 1 are slidably connected, so that the fitting block 5 is fitted into the first sliding groove 6. The side sealing plate 4 and the partition plate 3 are fixedly connected, so they are installed together on the slider 1, thus achieving quick installation on the guide rail 2.

[0017] In the prior art, quick installation requires disassembly methods such as screws to replace the slider 1 in order to replace the internal rotating ball. However, this device can quickly replace the ball bearing part 22 by means of snap-fit ​​and sliding, making it easier to adjust the preload and thus enabling faster disassembly and assembly.

[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
