Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine guide rail technology, specifically a wear-resistant laser cutting machine guide rail. Background Technology

[0002] The guide rail of a laser cutting machine is a key component that supports and guides the laser cutting head to move precisely within the working area. The design and quality of the guide rail system directly affect the cutting accuracy, stability, and service life of the laser cutting machine.

[0003] Laser cutting machine guideways require regular lubrication during use, primarily because friction occurs between the guideway and the slider during prolonged operation. According to tribological principles, friction is determined by factors such as the material properties, surface roughness, contact pressure, and relative speed of the contact surfaces. In the high-precision motion of a laser cutting machine, the guideway system needs to withstand significant loads and frequent movements, leading to increased friction between the slider and guideway. Without proper lubrication, this friction increases, causing wear, exacerbating surface roughness, increasing motion resistance, and resulting in unstable system movement, affecting cutting accuracy. Furthermore, lack of lubrication can cause the temperature between the guideway and slider surfaces to rise. According to thermodynamic principles, when the contact surface temperature rises, the material expands or deforms, further affecting the system's geometric stability. Lubricating oil reduces friction and wear by forming an oil film on the contact surfaces and effectively disperses generated heat, thereby extending the guideway's lifespan and maintaining motion accuracy. However, manual lubrication requires regular application, and the lubricating oil can be affected by environmental pollution, temperature changes, or overuse, leading to unstable lubrication effects and causing inconvenience for equipment maintenance.

[0004] In view of this, we propose a wear-resistant guide rail for laser cutting machines. Utility Model Content

[0005] The purpose of this invention is to provide a wear-resistant guide rail for laser cutting machines, which solves the problem of the tedious need for regular manual lubrication of laser cutting machine guide rails.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wear-resistant laser cutting machine guide rail includes a machine body, a laser cutting head, and a guide rail. The guide rail is equipped with a lubrication mechanism, which includes: an oil reservoir threadedly connected to the inner wall of the guide rail; a hollow connecting channel formed in the inner wall of the guide rail, the inner wall of which communicates with the inner wall of the oil reservoir; a middle connecting groove, a lower connecting groove, and an upper connecting groove formed in the inner wall of the guide rail; one end of a return spring fixedly connected to the inner wall of the guide rail; the other end of the return spring fixedly connected to a lower guide post; a middle guide post fixedly connected to the top of the lower guide post; an upper guide post fixedly connected to the top of the middle guide post; the top of the upper guide post is arc-shaped; a through hole is formed in the outer wall of the middle guide post; and the inner wall of the middle connecting groove is piston-connected to the middle guide post. The oil reservoir is equipped with a reminder mechanism to indicate insufficient lubricating oil in the reservoir.

[0008] Preferably, a laser cutting head is provided on the top of the machine body, and the laser cutting head is slidably connected to the machine body via a guide rail.

[0009] Preferably, the top of the oil storage tank has an inlet for refueling.

[0010] Preferably, there are several middle connecting grooves, lower connecting grooves, and upper connecting grooves, and the inner wall of the lower connecting groove is connected to the inner wall of the hollow connecting channel.

[0011] Preferably, the bottom of the lower guide post is provided with a chamfer, which is used to facilitate connection with the lower connecting groove piston.

[0012] Preferably, the reminder mechanism includes a cover, which is disposed on the top of the oil storage tank. A slide rod is slidably connected to the inner wall of the cover. A float is fixedly connected to the bottom of the slide rod, and a cylindrical block is fixedly connected to the top of the slide rod.

[0013] Preferably, a buzzer is provided on the top of the cover, the buzzer is located at the bottom of the cylindrical block, and a switch is provided on the top of the buzzer.

[0014] By employing the above technical solution, this utility model provides a wear-resistant laser cutting machine guide rail. It possesses at least the following beneficial effects:

[0015] 1. This utility model incorporates a lubrication mechanism. When no laser cutting head slides over the top of the guide rail, the lower guide post, middle guide post, and upper guide post are positioned as follows under the action of the return spring: Figure 4At this position, the upper guide post is connected to the piston in the upper connecting groove, preventing the lubricating oil in the middle connecting groove from being output through the upper connecting groove. When the laser cutting head slides over it, the lower guide post, middle guide post, and upper guide post move downwards. At this time, the lower guide post connects to the piston in the lower connecting groove, preventing the lubricating oil in the hollow connecting channel from passing through the lower connecting groove. Meanwhile, the upper guide post moves downwards and is no longer connected to the piston in the upper connecting groove. At this point, the lubricating oil in the middle connecting groove is output through the upper connecting groove under the action of the submerged upper guide post, lubricating the guide rail. When the laser cutting head presses down on the upper guide post and moves it halfway downwards, the upper guide post will not disengage from the piston connection in the upper connecting groove. Only when the upper connecting groove and the upper guide post are disengaged from the piston will the lower guide post connect with the piston in the lower connecting groove. This provides real-time lubrication, allowing the flow of lubricating oil to be adjusted in real time according to whether the laser cutting head passes over the guide rail. As the laser cutting head slides, lubricating oil is effectively delivered to the guide rail for lubrication, ensuring that the guide rail is always properly lubricated, reducing friction and wear, making the guide rail more wear-resistant, and this automatic lubrication design reduces manual intervention, ensures continuous lubrication of the system, and simplifies equipment maintenance.

[0016] 2. This utility model incorporates a reminder mechanism. When the lubricating oil level in the oil tank is low, the float in the oil tank moves downward under the influence of gravity, causing the sliding rod and cylindrical block to move downward as well. The cylindrical block then touches the buzzer to sound an alarm, reminding the staff to add lubricating oil. This prevents insufficient lubrication due to insufficient oil level, thereby reducing the risk of friction, wear, or equipment failure. Attached Figure Description

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 7As shown, this utility model provides a technical solution: a wear-resistant laser cutting machine guide rail, including a machine body 1, a laser cutting head 2, and a guide rail 3. A lubrication mechanism 4 is provided on the guide rail 3. The lubrication mechanism 4 includes: an oil reservoir 41, which is threadedly connected to the inner wall of the guide rail 3; a hollow connecting channel 42 is formed on the inner wall of the guide rail 3, and the inner wall of the hollow connecting channel 42 communicates with the inner wall of the oil reservoir 41; a middle connecting groove 43 is formed on the inner wall of the guide rail 3; and a lower connecting groove is formed on the inner wall of the guide rail 3. The guide rail 3 has an upper connecting groove 45 on its inner wall. One end of a return spring 46 is fixedly connected to the inner wall of the guide rail 3. The other end of the return spring 46 is fixedly connected to a lower guide post 47. A middle guide post 48 is fixedly connected to the top of the lower guide post 47, and an upper guide post 49 is fixedly connected to the top of the middle guide post 48. The top of the upper guide post 49 is arc-shaped to facilitate downward movement during sliding. A through hole is provided on the outer wall of the middle guide post 48 to allow lubricating oil to pass through. When stationary... The outer wall of the upper guide column 49 is connected to the piston of the upper connecting groove 45, the inner wall of the middle connecting groove 43 is connected to the piston of the middle guide column 48, and the lower guide column 47 will connect to the piston of the lower connecting groove 44 when it moves downward; a reminder mechanism 5 is provided on the oil storage tank 41, which is used to remind that the lubricating oil in the oil storage tank 41 is insufficient, so that the staff can add it in time; a laser cutting head 2 is provided on the top of the machine body 1, and the laser cutting head 2 is slidably connected to the machine body 1 through the guide rail 3; an inlet is opened on the top of the oil storage tank 41. The top inlet of the oil storage tank 41 is used for refueling. When threaded connection is made, the top inlet of the oil storage tank 41 is rotated to the top to ensure that the oil in the oil storage tank 41 enters the hollow connecting channel 42 under the action of gravity. Several middle connecting grooves 43, lower connecting grooves 44 and upper connecting grooves 45 are provided. The inner wall of the lower connecting groove 44 is connected to the inner wall of the hollow connecting channel 42 for conveying lubricating oil. The bottom of the lower guide post 47 is provided with a chamfer. The chamfer of the lower guide post 47 is used to facilitate piston connection with the lower connecting groove 44.

[0028] The reminder mechanism 5 includes a cover 51, which is located on the top of the oil storage tank 41. A slide rod 52 is slidably connected to the inner wall of the cover 51. A float 53 is fixedly connected to the bottom of the slide rod 52. A cylindrical block 54 is fixedly connected to the top of the slide rod 52. A buzzer 55 is located on the top of the cover 51 and is located at the bottom of the cylindrical block 54. A switch is located on the top of the buzzer 55.

[0029] In use, the wear-resistant laser cutting machine guide rail of this utility model involves threading an oil reservoir 41 onto the guide rail 3, then injecting lubricating oil. The lubricating oil in the oil reservoir 41 enters the middle connecting groove 43 through the hollow connecting channel 42 and the lower connecting groove 44. When no laser cutting head 2 slides across the top of the guide rail 3, the lower guide post 47, the middle guide post 48, and the upper guide post 49 are positioned as follows under the action of the return spring 46. Figure 4At this position, the upper guide post 49 is piston-connected to the upper connecting groove 45, preventing the lubricating oil in the middle connecting groove 43 from being output through the upper connecting groove 45. When the laser cutting head 2 slides past, the lower guide post 47, middle guide post 48, and upper guide post 49 move downwards. At this time, the lower guide post 47 is piston-connected to the lower connecting groove 44, preventing the lubricating oil in the hollow connecting channel 42 from passing through the lower connecting groove 44. Meanwhile, the upper guide post 49 moves downwards and is no longer piston-connected to the upper connecting groove 45. At this time, the lubricating oil in the middle connecting groove 43 is output through the upper connecting groove 45 under the action of the submerged upper guide post 49, lubricating the guide rail 3. When the laser cutting head 2 presses down on the upper guide post 49 and moves downwards halfway, the upper guide post 49 will not disengage from the piston connection with the upper connecting groove 45. Only when the upper connecting groove 45 and the upper guide post 49 are disengaged from the piston connection will the lower guide post 47 connect with the piston of the lower connecting groove 44. This provides real-time lubrication, allowing the flow of lubricating oil to be adjusted in real time according to whether the laser cutting head 2 passes through the guide rail 3. As the laser cutting head 2 slides, lubricating oil is effectively delivered to the guide rail 3 for lubrication, ensuring that the guide rail 3 always maintains proper lubrication, reducing friction and wear, making the guide rail 3 more wear-resistant, and this automatic lubrication design can reduce manual intervention, ensure continuous lubrication of the system, and simplify equipment maintenance.

[0030] When the lubricating oil in the oil storage tank 41 is at a low level, the float 53 in the oil storage tank 41 moves downward under the action of gravity, causing the slide bar 52 and the cylindrical block 54 to move downward as well. The cylindrical block 54 moves downward and touches the buzzer 55 to sound an alarm, reminding the staff to add lubricating oil to avoid insufficient lubrication due to insufficient oil, thereby reducing the risk of friction, wear or equipment failure.

[0031] The buzzer 55 is existing technology and will not be described in detail in this application.
