[0025] The mounting plate 1 provides support for the whole device, and the guide rail 2 cooperates with the sliding block 3 to realize the sliding of the components. The sliding block 3 bottom square groove 4 is used to install the square plate 5, the square plate 5 bottom rubber block 6 can buffer and shock absorption, the top pressure column 7 can act under the action of pressure, the outer load spring 8 of pressure column 7 plays a buffering and pressure regulating role. The bearing plate 9 connects the pressure column 7 and the slide bar 10, the outer pressure distribution spring 11 of the slide bar 10 further disperses the pressure, the fixed block 12 on one side of the sliding block 3 cooperates with the slide bar 10 to ensure stable movement, and the rubber pressing block 13 at the bottom of the slide bar 10 plays a buffering and stabilizing role.

[0026] The top of the mounting plate 1 is provided with a first slot 14, the inner wall of the first slot 14 is fixedly connected with a first air pipe 15, the top of the first air pipe 15 is fixedly connected with a plurality of first air injection pipes 16 at equal intervals, the outer surface of the first air pipe 15 penetrates the mounting plate 1 and extends to the outside of the mounting plate 1, the other end of the first air pipe 15 is fixedly connected with a gas distribution box 17, the top of the mounting plate 1 is provided with a second slot 18, the inner wall of the second slot 18 is fixedly connected with a second air pipe 19, the top of the second air pipe 19 is fixedly connected with a plurality of second air injection pipes 20 at equal intervals, the outer surface of the second air pipe 19 penetrates the mounting plate 1 and extends to the outside of the mounting plate 1, the other end of the second air pipe 19 is fixedly connected with the outside of the gas distribution box 17, and the other side of the gas distribution box 17 is fixedly connected with an air inlet pipe 21.

[0027] The first slot 14 and the second slot 18 are respectively used to fix the first air pipe 15 and the second air pipe 19. The air inlet pipe 21 is responsible for introducing the gas from the external gas source into the gas distribution box 17, which will evenly distribute the gas to the first air pipe 15 and the second air pipe 19. The first air pipe 15 and the second air pipe 19 are respectively equipped with the first air jet pipe 16 and the second air jet pipe 20, which can accurately spray gas to the working position of the guide rail 2 and the sliding block 3. On the one hand, the sprayed gas can take away the heat generated by the guide rail 2 and the sliding block 3 during operation, thereby reducing the temperature and avoiding the influence of high temperature on the performance and service life of the components; on the other hand, the high-speed airflow can blow away the debris falling on the guide rail 2, preventing the debris from entering the gap between the sliding block 3 and the guide rail 2, effectively avoiding excessive wear caused by debris jamming, and ensuring that the sliding block 3 always slides smoothly and stably on the guide rail 2.

[0032] The tool slot 25 is provided on the top of the mounting plate 1.

[0033] The tool slot 25 provided on the top of the mounting plate 1 provides a convenient space for operators to store commonly used tools.

[0034] The mounting plate 1 is provided with a bolt 26 on the top.

[0035] The bolt 26 on the top of the mounting plate 1 is used to fix it on the numerical control machine tool, ensuring the stable operation of the linear guide rail device and the machining accuracy of the machine tool.

[0036] The working principle of the linear guide rail device of the numerical control machine tool provided by the utility model is as follows: firstly, the mounting plate 1 provides a stable support foundation for the whole device, the guide rail 2 is fixed on the top of the mounting plate 1, the sliding block 3 can freely slide on the outer surface of the guide rail 2, and the relative movement function between components is realized, which is the basic structure guarantee for normal operation of the device. When the pressure applied on the bearing plate 9 suddenly increases, the pressure column 7 connected with the bearing plate 9 is subjected to downward force and starts to press down. The load spring 8 on the outer surface of the pressure column 7 will shrink due to the downward pressing of the pressure column 7, and part of the pressure is converted into elastic potential energy and stored. With the continuous pressing of the pressure column 7, the square plate 5 connected with the bottom of the pressure column 7 gradually separates from the square groove 4 at the bottom of the sliding block 3, so that the rubber block 6 at the bottom of the square plate 5 is in contact with the surface of the guide rail 2. At this time, a relatively large friction force is generated between the rubber block 6 and the guide rail 2, and the sliding of the sliding block 3 on the guide rail 2 is prevented. Because if the sliding block 3 continues to slide, the relative position between the cutter and the workpiece will deviate greatly, and then the machined part becomes a defective product or a waste product. At the same time, the rubber block 6 plays a role of buffering and shock absorption. Then, at the same time, the sliding rod 10 at the bottom of the bearing plate 9 will be pressed down synchronously with the bearing plate 9, and the pressure distribution spring 11 outside the sliding rod 10 will also be compressed, and the pressure is further dispersed. The rubber pressing block 13 at the bottom of the sliding rod 10 contacts the surface of the mounting plate 1, provides additional buffering and stabilizes the device. Finally, when the pressure returns to the normal range, the load spring 8 and the pressure distribution spring 11 will restore the deformation by virtue of the elasticity thereof, the pressure column 7 rises, the square plate 5 returns to the square groove 4, the rubber block 6 is separated from the guide rail 2, the rubber pressing block 13 is separated from the mounting plate 1, and the device returns to the normal sliding working state.

[0037] Compared with the related art, the linear guide rail device of the numerical control machine tool provided by the utility model has the following advantages

[0038] Beneficial effects:

[0039] The utility model provides a kind of linear guide rail device of numerical control machine tool, when bearing plate 9 pressure increases suddenly, pressure column 7 presses down and makes load spring 8 shrink, square plate 5 separates from square groove 4, rubber block 6 is in contact with guide rail 2, both can increase friction force and can buffer shock absorption.

[0040] The above-mentioned is only the embodiment of the utility model, and does not limit the patent range of the utility model, and any equivalent structure or equivalent process conversion using the contents of the utility model specification and drawings, or direct or indirect application in other related technical fields, is also included in the patent protection range of the utility model.
