Description

Technical Field

[0001] This utility model relates to the field of cutting machine guide rail technology, specifically a laser cutting machine guide rail with shock absorption and noise reduction. Background Technology

[0002] The guide rail is a crucial component in a laser cutting machine, used to support and guide the cutting head to move precisely along a predetermined path. The design and precision of the guide rail are critical to the performance, cutting quality, and stability of the laser cutting machine.

[0003] During use, dust, metal shavings, and other tiny particles easily adhere to the guide rails of laser cutting machines. This is because the heat generated during cutting and the high temperature of the laser beam cause metal shavings, cutting fumes, and dust from the material being cut to be released into the surrounding air, where they then deposit on the guide rails. According to fluid mechanics principles, the high temperature and high-speed airflow of the laser cutting machine bring these tiny particles to the vicinity of the guide rails. Due to their material and motion characteristics, the guide rail surface easily becomes an accumulation point for these particles. Dust and particles on the guide rail surface increase sliding friction, altering the smoothness of the guide rail and making the contact surface between the slider and the guide rail rougher. According to tribology principles, increased surface roughness leads to increased friction at the contact surface, thereby increasing motion resistance and energy loss, and even affecting the precise movement of the cutting head. Prolonged dust accumulation can also cause wear on the guide rails, altering their original geometry and affecting the cutting machine's accuracy. Furthermore, dust accumulation can form a thin film, changing the thermal conductivity of the guide rail surface, leading to localized overheating or thermal expansion and contraction, thus exacerbating guide rail deformation. According to thermodynamic principles, an increase in the temperature of the guide rail surface will cause changes in its physical properties, further affecting the system's stability and accuracy. Therefore, dust and particles on the guide rail not only affect the smoothness of the guide rail's movement but also negatively impact the overall accuracy, lifespan, and working efficiency of the laser cutting machine.

[0004] In view of this, we propose a vibration-damping and noise-reducing guide rail for laser cutting machines. Utility Model Content

[0005] The purpose of this utility model is to provide a shock-absorbing and noise-reducing laser cutting machine guide rail. This shock-absorbing and noise-reducing laser cutting machine guide rail solves the problem that dust and metal chips adhering to the surface of the laser cutting machine guide rail increase friction, change heat conduction performance, lead to increased movement resistance, reduced precision, and thus affect the cutting effect and equipment stability.

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

[0007] A vibration-damping and noise-reducing laser cutting machine guide rail includes a machine body, a laser cutting head, and a moving mechanism. The moving mechanism includes a bottom electric support, a top electric support, and a connecting guide rail. A cleaning mechanism is provided on the connecting guide rail. The cleaning mechanism includes: a guide rail bracket, which is mounted on the connecting guide rail. A top electric support is fixedly connected to the top of the guide rail bracket. An air inlet is fixedly connected to the inner wall of the top electric support. A main pipe is fixedly connected to the air inlet. An insertion storage box is inserted into the outer wall of the main pipe. The outer wall of the insertion storage box is inserted into the inner wall of the top electric support. A branch pipe is fixedly connected to the inner wall of the main pipe. A reinforcing mechanism is provided on the branch pipe for wiping the connecting guide rail.

[0008] Preferably, a laser cutting head is provided on the top of the machine body, and a moving mechanism is provided on the machine body.

[0009] Preferably, the bottom electric support is located on the top of the machine body, and a top electric support is provided on the top of the bottom electric support.

[0010] Preferably, both the bottom electric bracket and the top electric bracket are provided with connecting guide rails at their bottoms.

[0011] Preferably, the inner wall of the plug-in storage box is hollow, and a filter screen is provided on the inner wall of the plug-in storage box.

[0012] Preferably, the reinforcing mechanism includes a first support rod, which is fixedly connected to the branch pipe. A connecting shaft is rotatably connected to the outer wall of the first support rod. A cleaning component is fixedly connected to the bottom of the connecting shaft. One end of a return spring is fixedly connected to the outer wall of the connecting shaft. The other end of the return spring is fixedly connected to the inner wall of the branch pipe. A second support rod is fixedly connected to the inner wall of the branch pipe. A fan blade shaft is rotatably connected to the inner wall of the second support rod. An arc-shaped frame is fixedly connected to the fan blade shaft. The top of the connecting shaft is located on the inner wall of the arc-shaped frame.

[0013] Preferably, the cleaning component is U-shaped to facilitate cleaning of the sides and top of the connecting rail.

[0014] By means of the above technical solution, this utility model provides a laser cutting machine guide rail with shock absorption and noise reduction.

[0015] It has at least the following beneficial effects:

[0016] 1. This utility model incorporates a cleaning mechanism. The air compressor hose is connected to the air inlet, and the high-pressure air in the inlet is discharged to the outside through the main pipe and the plug-in storage box. At this time, the air flow rate in the main pipe is fast, while the air flow rate in the branch pipes is slow. According to Bernoulli's principle, the faster the fluid flow, the lower the fluid pressure. This causes the air in the branch pipes to move towards the main pipe, creating a negative pressure at the bottom of the branch pipes. This adsorbs impurities and dust on the connecting guide rails and then enters the plug-in storage box along the main pipe for storage. This effectively cleans the surface of the connecting guide rails, reduces the impact of dust and impurities on cutting accuracy, and ensures the stable operation of the laser cutting machine.

[0017] 2. This utility model incorporates a reinforcing mechanism. The airflow within the pipe drives the fan blades to rotate, which in turn drives the arc-shaped frame to rotate. As the arc-shaped frame rotates, the connecting shaft reciprocates under the action of a spring return spring. For example, in... Figure 5 , Figure 6 In the case shown, one side of the inner wall of the arc-shaped frame abuts against the connecting shaft. Under the action of the arc-shaped frame, the connecting shaft stretches the return spring. When the arc-shaped frame rotates half a turn, the connecting shaft will rotate to the other side of the inner wall of the arc-shaped frame under the action of the return spring. Since the groove inside the arc-shaped frame is elliptical, it can smoothly abut against the connecting shaft during the rotation, causing the connecting shaft to rotate back and forth. The connecting shaft drives the cleaning component to rotate back and forth, cleaning the connecting guide rail. This allows stubborn impurities on the surface of the connecting guide rail to be continuously wiped and loosened, making it easier for the cleaning mechanism to absorb and remove them.

[0026] 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 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 6 As shown, this utility model provides a technical solution: a vibration-damping and noise-reducing laser cutting machine guide rail, including a machine body 1, a laser cutting head 2, and a moving mechanism 3. The moving mechanism 3 includes a bottom electric support 31, a top electric support 32, and a connecting guide rail 33. A cleaning mechanism 4 is provided on the connecting guide rail 33. The cleaning mechanism 4 includes: a guide rail support 42, which is set on the connecting guide rail 33 to ensure that the connecting guide rail 33 can stably bear and guide the movement. A top electric support 32 is fixedly connected to the top of the guide rail support 42. An air inlet 43 is fixedly connected to the inner wall of the top electric support 32. A main pipe 45 is fixedly connected to the air inlet 43. An insertion storage box 44 is inserted into the outer wall of the main pipe 45. The outer wall of the insertion storage box 44 is inserted into the inner wall of the top electric support 32. A branch pipe 46 is fixedly connected to the inner wall of the main pipe 45. A reinforcing mechanism 5 is provided on the branch pipe 46 for wiping the connecting guide rail 33.

[0028] A laser cutting head 2 is installed on the top of the machine body 1. A moving mechanism 3 is also installed on the machine body 1. The moving mechanism 3 plays a crucial role in the laser cutting machine. Its function is to enable the fixed workpiece to move precisely along the guide rails such as the X-axis and Y-axis on the machine body 1, so as to facilitate the cutting by the laser cutting head 2. The bottom electric support 31 is installed on the top of the machine body 1. A top electric support 32 is installed on the top of the bottom electric support 31. Both the bottom electric support 31 and the top electric support 32 are equipped with connecting guide rails 33. The connecting guide rails 33 enable the bottom electric support 31 and the top electric support 32 to slide back and forth stably. The bottom electric support 31 and the top electric support 32 can move freely. The inner wall of the insertion storage box 44 is hollow. A filter screen is installed on the inner wall of the insertion storage box 44. When the air in the main pipe 45 passes through the insertion storage box 44 to the outside, the filter screen of the insertion storage box 44 filters and stores dust and impurities.

[0029] The reinforcing mechanism 5 includes a support rod 51, which is fixedly connected to the branch pipe 46. A connecting shaft 52 is rotatably connected to the outer wall of the support rod 51. A cleaning component 53 is fixedly connected to the bottom of the connecting shaft 52. One end of a return spring 54 is fixedly connected to the outer wall of the connecting shaft 52. The other end of the return spring 54 is fixedly connected to the inner wall of the branch pipe 46. A second support rod 55 is fixedly connected to the inner wall of the second support rod 55. The shaft of a fan blade 56 is rotatably connected to the inner wall of the second support rod 55. An arc-shaped frame 57 is fixedly connected to the shaft of the fan blade 56. The top of the connecting shaft 52 is located on the inner wall of the arc-shaped frame 57. The cleaning component 53 is U-shaped and is used to facilitate cleaning of the sides and top of the connecting guide rail 33.

[0030] In use, the vibration-damping and noise-reducing guide rail of this utility model connects the air compressor hose to the air inlet 43. The high-pressure air in the air inlet 43 is discharged to the outside through the main pipe 45 and the plug-in storage box 44. At this time, the air flow rate in the main pipe 45 is fast, while the air flow rate in the branch pipe 46 is slow. According to Bernoulli's principle, the faster the fluid flow, the lower the fluid pressure. This causes the air in the branch pipe 46 to move towards the main pipe 45, creating a negative pressure at the bottom of the branch pipe 46. This negative pressure attracts impurities and dust from the connecting guide rail 33, which then enter the plug-in storage box 44 along the main pipe 45 for storage. This effectively cleans the surface of the connecting guide rail 33, reduces the impact of dust and impurities on cutting accuracy, and ensures the stable operation of the laser cutting machine.

[0031] Simultaneously, the airflow within the branch pipe 46 drives the fan blades 56 to rotate, which in turn drives the arc-shaped frame 57 to rotate. As the arc-shaped frame 57 rotates, the connecting shaft 52 reciprocates under the action of the spring return spring 54, for example, in... Figure 5 , Figure 6In the case shown, one side of the inner wall of the arc-shaped frame 57 abuts against the connecting shaft 52. Under the action of the arc-shaped frame 57, the connecting shaft 52 stretches the return spring 54. When the arc-shaped frame 57 rotates half a turn, the connecting shaft 52 will rotate to the other side of the inner wall of the arc-shaped frame 57 under the action of the return spring 54. Since the groove inside the arc-shaped frame 57 is elliptical, it can smoothly abut against the connecting shaft 52 during the rotation, causing the connecting shaft 52 to rotate back and forth. The connecting shaft 52 drives the cleaning component 53 to rotate back and forth, cleaning the connecting guide rail 33, so that the stubborn impurities on the surface of the connecting guide rail 33 are continuously wiped and loosened, making it easy for the cleaning mechanism 4 to absorb them away.

[0032] By reducing dust on the guide rail surface, noise and vibration are reduced.
