Description

Technical Field

[0001] The utility model relates to a linear guide rail, in particular to a linear guide rail with adjustable spacing for numerically controlled machine tools. Background Art

[0002] Linear guides for CNC machine tools are important mechanical components, primarily used to achieve precise linear motion of various machine tool components. Linear guides utilize high-precision balls or rollers to enable precise linear motion of machine tool components along the guides. Linear guides utilize high-precision balls or rollers to enable precise linear motion of machine tool components along the guides. Reasonable guide design allows them to withstand the heavy loads generated during machine tool operation, ensuring stable operation. Compared to traditional sliding guides, linear guides offer less friction, significantly improving machine tool efficiency and lifespan.

[0003] During the installation process, if there is an error in the guide rail spacing, it may cause the moving parts to become stuck, non-parallel, or even wear due to the inability to adjust, affecting the normal operation and accuracy of the equipment.

[0004] It should be noted that the above content falls within the technical cognition of the utility model applicant and does not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the purpose of this utility model is to provide a linear guide rail for CNC machine tools with adjustable spacing.

[0006] To achieve the above-mentioned purpose, the present invention proposes a linear guide rail for CNC machine tools with adjustable spacing, comprising two bases:

[0007] A horizontal plate is fixedly provided at the middle position of the top of the two bases, and a linear guide rail is fixedly provided at the top of the two horizontal plates. Strip grooves are opened on both sides of the top of the two bases, and a sliding column is slidably provided inside each of the strip grooves. One end of the sliding column arranged in pairs is hinged to the two ends of the corresponding horizontal frame, and the intersection position between the two horizontal frames is connected by a connecting shaft. Two rod seats are fixed at the middle position of the bottom end of the two bases, and the four rod seats are connected to the corresponding two sliding rods.

[0008] In one example, both ends of the two sliding rods are fixedly connected to the side walls of the two side panels, and the two side panels are fixedly arranged on both sides of the top end of the base.

[0009] In one example, a threaded hole is formed inside each of the sliding posts, and a limiting nut is threadedly connected inside each of the threaded holes.

[0010] In one example, a fixing column is fixedly provided at the bottom end of the connecting shaft, and the bottom end of the fixing column is fixedly connected to the middle position of the top end of the base.

[0011] In one example, the top end of the connecting shaft is threadedly connected to a limit rotary disc.

[0012] The utility model provides a linear guide rail for CNC machine tools with adjustable spacing, which can bring the following beneficial effects:

[0013] The utility model is cross-arranged through side panels, a base, a sliding rod, a rod seat, a pedestal, a cross frame, a cross plate, a linear guide rail, a strip slot, a sliding column, a threaded hole, a limit nut, a fixing column, a limit disc and a connecting shaft. The two cross frames can drive the two linear guide rails to move toward or away from each other during relative rotation, thereby achieving the adjustment of the spacing between the two linear guide rails. Therefore, fine-tuning is allowed according to actual conditions during the installation process, which simplifies the installation process and reduces assembly problems caused by mismatched guide rail spacing. It can also adapt to workpieces of different specifications and sizes, enhances the versatility of the equipment, and reduces the demand for guide rails of different models.

[0025] like Figures 1 to 3 As shown, the embodiment of the present invention provides a linear guide rail for a CNC machine tool with adjustable spacing, comprising two bases 5:

[0026] A horizontal plate 7 is fixedly provided at the middle position of the top of the two bases 5, and a linear guide rail 8 is fixedly provided at the top of the two horizontal plates 7. Strip grooves 9 are provided on both sides of the top of the two bases 5, and a sliding column 10 is slidably provided inside each of the strip grooves 9. One end of the sliding column 10 staggered in pairs is hinged to the two ends of the corresponding horizontal frame 6, and the intersection position between the two horizontal frames 6 is connected by a connecting shaft 15. Two rod seats 4 are fixed at the middle position of the bottom end of the two bases 5, and the four rod seats 4 are connected to the corresponding two sliding rods 3.

[0027] Specifically, both ends of the two sliding rods 3 are fixedly connected to the side walls of the two side panels 1 , respectively, and the two side panels 1 are fixedly arranged on both sides of the top end of the base 2 .

[0028] Specifically, a threaded hole 11 is formed inside each of the sliding posts 10 , and a limiting nut 12 is threadedly connected inside each of the threaded holes 11 .

[0029] Specifically, a fixing column 13 is fixedly provided at the bottom end of the connecting shaft 15 , and the bottom end of the fixing column 13 is fixedly connected to the middle position of the top end of the base 2 .

[0030] Specifically, the top end of the connecting shaft 15 is threadedly connected to the limiting rotary disc 14 .

[0031] Working principle: When in use, rotate the connecting shaft 15, and the connecting shaft 15 rotates with the fixed column 13 as the axis. The intersection between the two cross frames 6 is the connecting shaft 15, and the two cross frames 6 rotate. Since the sliding column 10 is placed inside the strip groove 9 on the base 5, the cross frame 6 rotates. The sliding column 10 slides inside the strip groove 9, and the rod seat 4 at the bottom of the base 5 slides on the sliding rod 3, and can move toward or away from each other. Then, the corresponding limiting nut 12 is rotated to the inside of the corresponding threaded hole 11, and the limiting nut 12 contacts the base 5 to limit the position of the two cross frames 6, and then the limiting dial 14 is rotated to limit and fix the middle position of the two cross frames 6.
