Its wear-resistant material and intelligent lubrication system significantly extend its service life.

[0003] Existing technologies disclose several utility model patents in the field of linear guide shaft technology for machine tools. Among them, utility model patent CN 207710293 U discloses a linear guide shaft for machine tools, including a shaft body; a first groove symmetrically provided on the outer surface of the shaft body, within which a first slider is plugged in; a second groove vertically oriented on the lower surface of the first slider, within which a first spring is located; a first through hole with an elongated cross-section symmetrically provided on the side of the first slider; and cylindrical pins symmetrically provided on the outer surface of the shaft body, which are slidably connected to the first through hole. Furthermore, an alloy body is provided at the center of the shaft body along its axial direction. The overall design is novel, effectively enhancing strength and movement stability.

[0004] Although the aforementioned utility model patent can stabilize the guide rail during machine tool operation, modern machine tools use intelligent networked production, and the required guide rails need to be added according to the actual situation, and the guide rails need to be replaced frequently, so improvements are needed.

[0005] Based on this, this utility model designs a high-strength machine tool linear guide shaft to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problem that although the above-mentioned utility model patent can stabilize the guide rail when the machine tool is working, the machine tool now uses intelligent network production, and the required guide rail needs to be added according to the actual situation, and the guide rail needs to be replaced frequently. Therefore, a high-strength machine tool linear guide rail shaft is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A high-strength machine tool linear guide shaft includes a worktable, a guide rail on the top of the worktable, multiple fixing holes on the surface of the guide rail, V-shaped sliding surfaces on both sides of the guide rail, and fixing blocks fixedly installed at both ends of the V-shaped sliding surfaces.

[0009] As a further description of the above technical solution:

[0010] The fixed block has a sliding groove inside, and the sliding groove has multiple symmetrical rectangular grooves inside.

[0011] As a further description of the above technical solution:

[0012] A fixed plate is slidably installed inside the sliding groove, and movable blocks are fixedly installed on both sides of the fixed plate.

[0013] As a further description of the above technical solution:

[0014] The movable block has a moving groove inside, and the fixed block has a rotating groove inside one side.

[0015] As a further description of the above technical solution:

[0016] A sliding column is fixedly installed inside the sliding groove, and the position of the sliding column corresponds to the position of the moving groove. A rotating column is rotatably installed inside the rotating groove, and the position of the rotating column corresponds to the position of the fixed plate. A slider is slidably installed on the surface of the guide rail, and multiple fixed grooves are opened on the top of the slider.

[0017] As a further description of the above technical solution:

[0018] The slider has multiple mounting grooves on both sides, a connecting groove on one side, and a V-shaped groove on the bottom, with the position of the V-shaped groove corresponding to the position of the V-shaped sliding surface.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0020] 1. In this utility model, by setting a fixed plate and a rotating column, after the V-shaped sliding surface is placed on the top of the required machine tool, the fixed plate is moved upward inside the sliding groove by rotating the rotating column. The fixed plate also drives the movable blocks fixed on both sides to slide inside the rectangular groove, so as to ensure that the fixed plate can move upward smoothly inside the sliding groove. When the fixed plate is raised and contacts the bottom of the worktable, the fixed plates on both sides of the worktable are moved and fixed to the bottom of the worktable to ensure that the fixed blocks are fixed on the top of the guide rail. Through the modular block disassembly structure, the high-strength machine tool guide rail shaft can achieve a generational improvement in terms of maintenance cost, thermal management accuracy and functional expandability.

[0021] 2. In this utility model, by setting a guide rail and a slider, a high-strength machine tool linear guide rail shaft is constructed. After the guide rail is fixed to the top of the worktable, the V-shaped groove at the bottom of the slider is installed corresponding to the V-shaped sliding surface. After the slider is installed on the surface of the guide rail, the collaborative design of the guide rail and the slider, through high rigidity structure, low friction transmission, long life materials and intelligent monitoring, significantly improves the machining accuracy, dynamic performance and reliability of the machine tool.

[0029] 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.

[0030] Please see the appendix Figure 1 -Appendix Figure 5This utility model provides a technical solution: a high-strength machine tool linear guide shaft, including a worktable 1, a guide rail 2 on the top of the worktable 1, multiple fixing holes 3 on the surface of the guide rail 2, V-shaped sliding surfaces 4 on both sides of the guide rail 2, and fixing blocks 5 fixedly installed at both ends of the V-shaped sliding surfaces 4.

[0031] The specific implementation method is as follows: a sliding groove 6 is provided inside the fixed block 5, and rectangular grooves 7 are symmetrically provided in multiple places inside the sliding groove 6.

[0032] By setting fixed blocks 5 and sliding grooves 6, fixed blocks 5 are fixedly installed at both ends of the guide rail 2. After the guide rail 2 is placed on the top of the worktable 1, multiple moving blocks 9 slide inside the sliding grooves 6 to the bottom of the worktable 1 to fix the fixed blocks 5 on the top of the worktable 1, ensuring that the machine tool can operate.

[0033] The specific implementation method is as follows: a fixed plate 8 is slidably installed inside the sliding groove 6, and movable blocks 9 are fixedly installed on both sides of the fixed plate 8.

[0034] By setting a fixed plate 8 and a movable block 9, rotating the rotating column 13 causes the fixed plate 8 to slide inside the sliding groove 6. By causing the movable blocks 9 fixedly installed on both sides of the fixed plate 8 to slide inside the rectangular groove 7, it is ensured that the fixed plate 8 can slide upward smoothly and smoothly transition to the bottom of the worktable 1 to fix the guide rail 2.

[0035] The specific implementation method is as follows: the movable block 9 has a movable groove 10 inside, and the fixed block 5 has a rotating groove 11 inside one side.

[0036] By setting the moving groove 10 and the rotating groove 11, the rotating column 13 slides inside the rotating groove 11, which drives the moving groove 10 to slide on the surface of the sliding column 12, so as to move the fixed plate 8 upward and attach the fixed plate 8 to the bottom of the worktable 1, so as to fix the guide rail 2 to the top of the worktable 1, ensuring that the machine tool can be installed in the next step.

[0037] The specific implementation method is as follows: a sliding column 12 is fixedly installed inside the sliding groove 6, and the position of the sliding column 12 corresponds to the position of the moving groove 10; a rotating column 13 is rotatably installed inside the rotating groove 11, and the position of the rotating column 13 corresponds to the position of the fixed plate 8; a slider 14 is slidably installed on the surface of the guide rail 2, and a number of fixed grooves 15 are provided on the top of the slider 14.

[0038] By setting up a sliding column 12 and a rotating column 13, rotating the rotating column 13 causes the fixing plate 8 to slide on the surface of the sliding column 12 to the bottom of the worktable 1, so as to fix the guide rail 2 to the top of the worktable 1. When the guide rail 2 needs to be replaced, simply rotate the rotating column 13 in the opposite direction to move the fixing plate 8 downward, so as to quickly disassemble the guide rail 2.

[0039] The specific implementation method is as follows: multiple mounting grooves 16 are provided on both sides of the slider 14, a connecting groove 17 is provided on one side of the slider 14, and a V-shaped groove 18 is provided on the bottom of the slider 14, and the position of the V-shaped groove 18 corresponds to the position of the V-shaped sliding surface 4.

[0040] By setting up slider 14 and V-groove 18, the V-groove 18 at the bottom of slider 14 matches the V-shaped sliding surface 4 on both sides of guide rail 2. By applying lubricating oil to the surface of V-shaped sliding surface 4, slider 14 can slide on the surface of guide rail 2 to carry out production operations.

[0041] Working principle and usage: When using this device, first place the guide rail 2 on the top of the workbench 1. By sliding the rotating column 13, which is rotatably installed inside the fixing block 5, inside the rotating groove 11, the fixing plate 8 is driven to slide upward inside the sliding groove 6. The fixing plate 8 also drives the moving blocks 9 on both sides to slide inside the rectangular groove 7. After the multiple fixing plates 8 move to the bottom of the workbench 1, the guide rail 2 is fixed to the top of the workbench 1. If the guide rail 2 needs to be replaced, simply flip the rotating column 13 to drive the fixing plate 8 away from the bottom of the workbench 1, so that the guide rail 2 can be disassembled and replaced or changed to a different production line.

[0042] 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.
