Description

Technical Field

[0001] This invention belongs to the field of laser cutting technology, and more specifically, relates to a guide rail oiling device for laser cutting. Background Technology

[0002] The guide rails used in laser cutting machines are a key component, primarily used to support and guide the smooth movement of moving parts along a predetermined direction. These guide rail systems must be designed with high precision, high stability, and good wear resistance to ensure accurate position control of the cutting head or worktable during high-speed movement.

[0003] The existing technology for laser cutting still has the following drawbacks:

[0004] First, during long-term operation, the guide rails of laser cutting equipment are prone to accumulating a large amount of metal dust, slag particles, and oil impurities. Traditional guide rail lubrication devices usually lubricate the guide rails directly, lacking an effective pre-cleaning and dust collection structure. This causes the lubricating oil to mix with the dust, forming sludge, which can easily affect the smoothness of the sliding of the guide rails and sliders and aggravate the wear of the guide rails.

[0005] Secondly, most guide rail lubrication structures use a continuous oil supply method, which cannot dynamically adjust the oil output according to the dust level on the guide rail surface. When there is a lot of dust on the guide rail surface, the lubricating oil continues to be output, which can easily cause local oil accumulation, uneven lubrication, and sludge buildup, thereby affecting the movement stability and cutting accuracy of the laser cutting equipment.

[0006] Third, during the lubrication process, the guide rail oiling device usually lacks a structure for uniform oil application and residual oil recycling. The lubricating oil tends to accumulate in local areas, making it difficult to form a uniform oil film on the guide rail surface. At the same time, excess lubricating oil cannot be effectively recycled, resulting in poor lubrication effect and significant lubricating oil waste.

[0007] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a laser-cut guide rail oiling device in order to achieve a more practical and valuable purpose. Summary of the Invention

[0008] This invention provides a guide rail oiling device for laser cutting, which overcomes the above-mentioned defects in the prior art.

[0009] The purpose and effect of the laser-cut guide rail oiling device of the present invention are achieved by the following specific technical means:

[0010] A guide rail oiling device for laser cutting includes a movable base and a laser cutting device disposed on the movable base. The movable base is provided with a housing, and further includes:

[0011] A cleaning component, disposed on the housing, is used to contact the surface of the guide rail when the movable seat moves along the guide rail;

[0012] A negative pressure chip collection assembly is disposed on the housing and located on the rear side of the cleaning assembly;

[0013] A feedback oil control component is disposed on the housing and cooperates with the negative pressure chip collection component to control the output state of lubricating oil according to the chip collection state in the negative pressure chip collection component;

[0014] An oil spreading component is disposed on the housing and located behind the negative pressure chip collection component, and is used to apply lubricating oil to the surface of the guide rail.

[0015] In this solution, the guide rail is first cleaned, then dust is sucked up, then oil is applied according to the dust state, and finally oil is applied evenly, which reduces the formation of sludge and improves the uniformity of lubrication.

[0016] Preferably, the cleaning assembly includes a track slider and a cleaning component disposed on the track slider, the track slider being used to slide with a guide rail, and the cleaning component being located in a groove of the track slider.

[0017] Preferably, the negative pressure dust collection assembly includes a dust collection frame, a dust collection chamber, and a collection chamber. The dust collection frame is connected to the dust collection chamber, and an inlet is provided between the dust collection chamber and the collection chamber. An air pump is installed inside the dust collection chamber.

[0018] Preferably, the negative pressure dust collection assembly further includes a filter screen, an arc-shaped component, and a torsion spring. The filter screen is hinged within the dust collection chamber, the free end of the filter screen slides in conjunction with the arc-shaped component, and the torsion spring is used to drive the filter screen to reset.

[0019] Preferably, the arc-shaped member is provided with a first limiting member and a second limiting member at intervals along the swing path of the filter screen, and the second limiting member is used to trigger the feedback oil control component when the filter screen deflects to a preset position.

[0020] Preferably, the feedback oil control assembly includes a valve body, a slide rod, a blocking component, and a telescopic drive component. The blocking component is disposed on the slide rod, and the telescopic drive component is connected to the slide rod to drive the blocking component to block or open the oil passage of the valve body.

[0021] Preferably, the valve body is connected to the oil chamber, a port is provided between the valve body and the oil pipe, and several through holes are provided between the oil pipe and the oil equalization component.

[0022] Preferably, a rotating shaft is rotatably provided inside the oil pipe, and a spiral component is provided on the rotating shaft. One end of the rotating shaft extends into the dust collection frame and is provided with a fan wheel. The fan wheel is used to drive the rotating shaft to rotate under the action of negative pressure airflow.

[0023] Preferably, the oil equalization assembly includes a frame, a roller seat slider, a rotating shaft, and an oil equalization roller. The roller seat slider is slidably disposed on the frame, the rotating shaft is rotatably disposed on the roller seat slider, and the oil equalization roller is disposed on the rotating shaft and used to contact the guide rail surface.

[0024] Preferably, the oil equalization assembly further includes a movable component, a scraper, an electric telescopic rod, and a linkage swing rod. The scraper is disposed on the movable component, the electric telescopic rod is connected to the movable component, and the linkage swing rod is connected between the movable component and the roller seat slider, so that when the scraper approaches the guide rail, it drives the oil equalization roller away from the guide rail. The inner side wall of the frame is provided with a flow guide, one side of which has an inclined structure. A small oil pump is installed on the outside of the frame. One end of the small oil pump is connected to the lower inner side of the frame, and the other end of the small oil pump is connected to the oil pipe.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] This invention discloses a guide rail lubrication device for laser cutting. By incorporating a cleaning component and a negative pressure chip collection component, the device scrapes and removes metal dust, slag particles, and attached impurities from the guide rail surface before lubrication. This reduces dust retention on the guide rail surface and prevents lubricating oil from directly mixing with large amounts of dust to form sludge, thereby improving the cleanliness of the guide rail surface and the stability of guide rail operation.

[0027] This invention discloses a guide rail lubrication device for laser cutting. Through a feedback oil control component, and utilizing the deflection state of a filter screen under the impact of dusty airflow, the opening and closing of the oil passage in the valve body is controlled. This allows for pausing or delaying oil output when dust levels are high, and resuming lubrication output once dust levels decrease. This achieves adjustment of lubrication output based on the dust level of the guide rail, reducing localized oil accumulation and sludge buildup, and improving the uniformity of guide rail lubrication. Furthermore, by incorporating an oil distribution component, an oil distribution roller rotates in contact with the guide rail to evenly coat the guide rail surface. A guide component directs the lubrication, and a small oil pump circulates excess lubrication, further improving the uniformity of lubrication distribution and utilization rate, thereby extending the service life of the guide rail and track slider.

[0028] The present invention discloses a guide rail oiling device for laser cutting. By setting up a movable part, a scraper, an electric telescopic rod and a linkage swing rod, the scraper can be brought closer to the guide rail for further scraping and cleaning when there is a lot of dust. At the same time, the oil spreading roller is driven away from the guide rail, reducing the contact between the oil spreading roller and the dust, thereby reducing the probability of impurities adhering to the outer wall of the oil spreading roller and improving the subsequent guide rail oiling effect.

[0061] Preferred options are shown in the appendix. Figure 7 Appendix Figure 10 The feedback oil control component includes a telescopic drive member 34, and a connector 31 is provided between the extended end of the telescopic drive member 34 and one end of the slide rod 32. A contact button is installed on the second limiting member 45, and the contact button transmits a signal to the control system to control the extension and retraction of the telescopic drive member 34.

[0062] Specific usage of this invention:

[0063] During operation, the movable seat 10 moves along the guide rail, driving the laser cutting equipment 50 to move synchronously in the horizontal direction. Two pairs of track sliders 12 are respectively engaged with the two guide rails for limiting sliding, so that the movable seat 10 and the laser cutting equipment 50 can move smoothly, so as to perform laser cutting on workpieces at different positions.

[0064] During the movement of the movable seat 10, the track slider 12 and the cleaning component 13 located on the front side first contact the guide rail surface. The cleaning component 13 scrapes off the metal dust, slag particles and attached impurities on the guide rail surface, causing the impurities to loosen or detach from the guide rail surface.

[0065] Subsequently, the air pump 46 starts, creating a negative pressure suction airflow within the dust collection frame 48. Dust and debris scraped off by the cleaning component 13 enter the dust collection chamber 38 under the influence of the negative pressure suction airflow. The dust-laden airflow entering the dust collection chamber 38 is filtered through the filter screen 42 and then discharged by the air pump 46, with the filtered impurities retained at the filter screen 42. The air pump 46 draws air intermittently; when the air pump 46 stops drawing air, the impurities on the filter screen 42 fall to the guide member 41 under their own weight and the resetting vibration of the filter screen 42, and are guided by the guide member 41 before entering the collection chamber 39 through the inlet 40 for storage, thereby reducing dust retention on the guide rail surface.

[0066] At the same time, the airflow in the dust collection frame 48 drives the impeller 49 to rotate, and the impeller 49 drives the rotating shaft 24 to rotate synchronously, providing power for the dispersion of lubricating oil in the subsequent oil pipe 23.

[0067] When the amount of dust entering the dust collection chamber 38 is large, the dust-laden airflow generates a large wind resistance thrust on the filter screen 42, causing the filter screen 42 to deflect significantly against the elastic force of the torsion spring 47. One end of the filter screen 42 moves from the first limiting member 44 to contact the second limiting member 45. After the contact button at the second limiting member 45 is triggered, the control system controls the telescopic drive member 34 to retract. The telescopic drive member 34 drives the slide rod 32 to move through the connecting member 31. The slide rod 32 drives several pairs of blocking members 33 to move, causing the blocking members 33 to block the oil passage in the valve body 27, thereby pausing or delaying the output of lubricating oil and preventing lubricating oil from entering the guide rail surface and mixing with the dust to form sludge when there is a lot of dust.

[0068] While pausing or delaying oil discharge, the control system extends several electric telescopic rods 20. These rods push the movable part 18 and the scraper 19 closer to the guide rail, causing the scraper 19 to contact the guide rail for further cleaning. During the movement of the movable part 18, the adjacent roller seat slider 15 moves via the linkage rocker arm 21. The roller seat slider 15 moves the rotating shaft 16 and the oil equalization roller 17 away from the guide rail, disengaging the oil equalization roller 17 from the guide rail and preventing impurities on the guide rail surface from adhering to the outer wall of the oil equalization roller 17 when there is a lot of dust.

[0069] As the amount of dust gradually decreases, the airflow resistance to the filter 42 decreases, and the filter 42 resets or deflects only slightly under the elastic force of the torsion spring 47, no longer triggering the second limit member 45. At this time, the control system controls the extension drive member 34 to extend, and the extension drive member 34 drives the blockage member 33 to reset through the connector 31 and the slide rod 32, so that the oil passage in the valve body 27 is reopened.

[0070] After the valve body 27 is opened, the lubricating oil in the oil chamber 29 enters the valve body 27 and flows into the oil pipe 23 through the port 35. The rotating shaft 24 rotates under the drive of the impeller 49, which in turn drives the spiral component 25 to rotate, causing the lubricating oil entering the oil pipe 23 to be dispersed along the length of the oil pipe 23. Subsequently, the lubricating oil flows into the frame 14 through several through holes 36.

[0071] Simultaneously, the control system controls several electric telescopic rods 20 to retract. The electric telescopic rods 20 drive the movable part 18 and the scraper 19 away from the guide rail, causing the scraper 19 to disengage from the guide rail. When the movable part 18 returns to its original position, it drives the adjacent roller seat slider 15 to move via the linkage rocker arm 21. The roller seat slider 15 drives the rotating shaft 16 and the oil equalization roller 17 to move closer to the guide rail, causing the oil equalization roller 17 to contact the guide rail.

[0072] As the movable seat 10 continues to move along the guide rail, the oil-spreading roller 17 rotates around the rotating shaft 16 under the friction of the guide rail. During its rotation, the oil-spreading roller 17 comes into contact with the lubricating oil inside the frame 14 and evenly spreads the lubricating oil on the surface of the guide rail. The guide member 22 guides the lubricating oil inside the frame 14 through its inclined surface, allowing the lubricating oil to flow fully to the oil-spreading roller 17 and improving the contact between the lubricating oil and the oil-spreading roller 17. The lubricating oil accumulated on the lower side inside the frame 14 is transported back to the oil pipe 23 by the small oil pump 26 to achieve lubricating oil recycling.

[0073] Therefore, the device can sequentially complete the following steps during the movement of the movable seat 10 along the guide rail: initial scraping of the guide rail surface, negative pressure dust suction, dust quantity judgment, pausing oil output and strengthening cleaning when there is a lot of dust, resuming oil output after the dust decreases, applying oil to the oil distribution roller 17, and recycling the remaining oil, thereby reducing sludge formation and improving the cleanliness and lubrication uniformity of the guide rail.

[0074] The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.
