Description

Technical Field

[0001] This utility model relates to the field of linear guide technology, and in particular to a modular connection structure for linear guides. Background Technology

[0002] A linear guide is a mechanical guiding system used to achieve linear motion. It mainly consists of a guide rail and a slider (or trolley). Precise linear motion is achieved by the slider sliding on the guide rail. Linear guides have wide applications in industrial and scientific research fields, and their design and performance have a significant impact on the accuracy and efficiency of equipment.

[0003] Currently, linear guide rail equipment uses a large number of rotating balls, which are prone to damage. Damaged rotating balls can lead to loss of lubrication between the sliding components and the guide rail, or the generation of uneven friction. This intensifies the direct contact between the sliding components and the guide rail, increases the coefficient of friction, and causes further wear. Increased friction not only reduces the smoothness of sliding but also easily leads to overheating, affecting the service life of the sliding components and the guide rail, thus impairing the practicality of the equipment.

[0004] Replacing a damaged rotating ball requires disassembling the entire sliding component. Existing sliding components are not easy to disassemble, leading to extended downtime and thus affecting overall production efficiency. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a modular connection structure for linear guides.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a modular connection structure for a linear guide rail, comprising a guide rail and a slider assembly, wherein there are multiple guide rails, and the slider assembly comprises a top plate. The bottom of the top plate is provided with two sets of clamping assemblies through an interlocking assembly. The clamping assembly comprises an upper clamping block, the bottom of the upper clamping block is provided with a third sliding groove, the third sliding groove is slidably connected to a lower clamping block, and a rotating groove is provided between the upper clamping block and the lower clamping block, wherein multiple rotating beads are provided in the rotating groove.

[0007] Preferably, a locking block is fixedly connected to the side wall of the guide rail, and a first sliding groove and a first locking slot are provided on the side of the guide rail away from the locking block. The first locking slot is located below the first sliding groove and communicates with the first sliding groove.

[0008] Preferably, the bottom of the top plate is provided with two sets of second sliding grooves corresponding to the clamping assembly, and the fitting assembly includes a fitting block fixedly installed on the top of the upper clamping block, the fitting block being slidably connected to the corresponding second sliding groove.

[0009] Preferably, side sliding members are fixedly installed on both sides of the upper clamping block and the lower clamping block, and the side sliding members on the same side of the upper clamping block and the lower clamping block correspond to each other. A partition is provided on both sides of the clamping assembly, and a fourth sliding groove is provided on the side wall of the partition. The fourth sliding groove is slidably connected to the side sliding member on the corresponding side.

[0010] Preferably, oil inlets are provided on the sides of the two partitions that are far apart from each other.

[0011] Preferably, the upper clamping block is provided with an oil guide port, the oil guide port is connected to the rotating groove, and an oil pipe is provided inside the top plate, which is used to connect the oil inlet and the oil guide port.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] 1. This device uses a snap-fit ​​mechanism to combine the upper and lower clamping blocks, allowing for quick disassembly and reassembly of the upper and lower clamping blocks without the need for complex tools or techniques. This enables the rapid removal and replacement of damaged rotating balls, significantly reducing equipment downtime, improving production efficiency, and preventing excessive wear caused by failure to replace damaged rotating balls in a timely manner, thereby extending the service life of the entire sliding system.

[0014] 2. This device delivers lubricating oil into the rotating groove through an oil inlet and an oil guide, causing the lubricating oil to adhere to the outer wall of multiple rotating balls. This effectively reduces friction between the slider assembly and the guide rail, extends the system's service life, lowers the failure rate, and improves the reliability of the equipment.

[0015] 3. This device connects multiple guide rails together by setting up locking blocks and a first locking slot. The number of locking blocks can be selected according to the required rail length to meet different specifications and application requirements. This avoids designing different linear guide rails for each length requirement, reduces manufacturing costs, and simplifies the assembly and disassembly process. It does not require the use of traditional screws and complex fixing devices, reduces installation time, and improves overall work efficiency. Attached Figure Description

Detailed Implementation

[0022] 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.

[0023] Reference Figures 1 to 5 A modular connection structure for a linear guide rail includes a guide rail 1 and a slider assembly. A locking block 4 is fixedly connected to the side wall of the guide rail 1. A first sliding groove 2 and a first locking slot 3 are provided on the side of the guide rail 1 away from the locking block 4. The first locking slot 3 is located below the first sliding groove 2 and communicates with the first sliding groove 2. There are multiple guide rails 1, which are connected together by the locking block 4 and the first locking slot 3. The number of locking blocks 4 is selected according to the required rail length to meet the application of different specifications and requirements. This avoids designing different linear guide rails for each length requirement, reducing manufacturing costs. Since the guide rail 1 is connected by the locking block 4 and the first locking slot 3, the disassembly and assembly process is simple. There is no need to use traditional screws and complex fixing devices. Just align the locking block 4 with the first sliding groove 2 and slide it into the first locking slot 3 to complete the installation or disassembly. This not only reduces the installation time but also reduces the tool requirements during the disassembly process, improving the overall work efficiency.

[0024] The slider assembly includes a top plate 5. Two sets of clamping components are provided at the bottom of the top plate 5. Two sets of second sliding grooves 6 corresponding to the clamping components are also provided at the bottom of the top plate 5. Each clamping component includes an upper clamping block 10. A fitting block 9 is fixedly installed on the top of the upper clamping block 10 and slidably connected to the corresponding second sliding groove 6. A third sliding groove 11 is provided at the bottom of the upper clamping block 10, and a lower clamping block 12 is slidably connected to the third sliding groove 11. A rotating groove is provided between the upper clamping block 10 and the lower clamping block 12. Multiple rotating balls 15 are arranged inside the moving groove. The rotating balls 15 act as rolling bearings, making the sliding process smoother, reducing direct friction between metals, and improving stability. An oil guide port 8 is provided on the upper clamping block 10, which is connected to the rotating groove. Side sliding members 13 are fixedly installed on both sides of the upper clamping block 10 and the lower clamping block 12, with the side sliding members 13 on the same side of the upper clamping block 10 and the lower clamping block 12 corresponding to each other. A partition plate 14 is provided on both sides of the clamping assembly. The side wall of 4 is provided with a fourth sliding groove 16, which is slidably connected to the corresponding side sliding member 13. The two partitions 14 are respectively provided with oil inlets 7 on the opposite sides. The top plate 5 is provided with an oil pipe (not shown in the figure), which is used to connect the oil inlet 7 and the oil guide 8. Lubricating oil is delivered to the rotating groove through the oil inlet 7 and the oil guide 8, so that the outer wall of multiple rotating balls 15 is covered with lubricating oil, which effectively reduces the friction between the slider assembly and the guide rail 1, extends the service life of the system, reduces the failure rate, and improves the reliability of the equipment. The snap-fit ​​connection method allows for quick replacement of the internal rotating balls 15, which greatly reduces maintenance time and improves the maintenance efficiency of the equipment. It is simpler than the traditional welding or bolt connection, making assembly and disassembly easier. Quick replacement of rotating balls 15 allows the performance of the components to be adjusted according to different working conditions or load requirements. Since the components can be replaced quickly, the downtime caused by maintenance can be reduced, thereby improving production efficiency.

[0025] In this invention, when a quick installation device is required, the guide rails 1 are first spliced ​​together. A locking block 4 is fixedly connected to one side surface of each guide rail 1 that needs to be spliced. The locking block 4 is slid down the first slide groove 2 from top to bottom. When it reaches the bottom of the first slide groove 2, it is slid to the right, allowing it to enter the first locking groove 3, thus locking the locking block 4 in place and preventing it from wobbling up and down. After the guide rails 1 are installed, the sliding components are assembled. First, the fitting block 9 on the upper clamping block 10 and the second slide groove 6 are fitted together. The second slide groove 6 is located on the top plate 5. After the upper clamping block 10 is fitted in, the lower clamping block 12 and the third slide groove 6 are then fitted together. The slide groove 11 engages, causing the upper clamping block 10 and the lower clamping block 12 to fit together. When the lower clamping block 12 engages with the third slide groove 11, some of the rotating beads 15 are inserted. Side sliding members 13 are provided on one side surface of both the upper clamping block 10 and the lower clamping block 12. When they fit together, the side sliding members 13 become integrated. Then, the partition plate 14 is installed from top to bottom, causing the fourth slide groove 16 to engage with the side sliding members 13, thus assembling the sliding block. Oil is then supplied through the oil inlet 7 and through the oil guide port 8 on the upper clamping block 10 to lubricate the rotating beads 15 during movement. Compared to existing technologies, this device has lower cost, a simpler lubrication system, and does not significantly increase the weight of the device, thus avoiding large physical deviations in the guide rail 1 during movement.

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.
