Description

Technical Field

[0001] This utility model relates to the field of machine tool guideway technology, and more specifically, to a self-circulating lubrication structure for machine tool guideways. Background Technology

[0002] In the daily operation of machine tool guideways, lubrication is a crucial factor in ensuring their normal operation and extending their service life. Traditional machine tool guideway lubrication methods typically rely on manual periodic application of lubricating oil, which has several drawbacks. On the one hand, manual operation makes it difficult to accurately control the amount of lubricating oil applied, easily resulting in uneven application. This leads to insufficient lubrication in some areas and excessive lubricating oil in others, causing waste and potentially exacerbating guideway wear due to the accumulation of impurities in the lubricating oil. On the other hand, manual periodic oil replenishment requires machine shutdown, affecting the machine tool's working efficiency and preventing the recycling of lubricating oil, thus increasing operating costs and environmental pollution risks.

[0003] A utility model patent with announcement number CN222359816U discloses a CNC machine tool guide rail lubrication device, including: a magnet, a first oil storage box fixedly connected to the bottom of the magnet by a connecting rod, an oil brush cotton provided on the inner surface of the first oil storage box, a second cleaning module provided on one side of the first oil storage box, a first nozzle symmetrically installed on the side of the second cleaning module away from the first oil storage box, two second cleaning modules symmetrically arranged vertically, a first cleaning module provided on both the left and right sides of the second cleaning module, and a second nozzle symmetrically arranged on the surface of the first cleaning module.

[0004] Although this utility model has the advantages of good protection for guide rails, convenient disassembly and assembly of scraper blades, and convenient use of screw lubrication components, there are still problems such as uneven application of lubricating oil and inability to recycle lubricating oil, resulting in waste of lubricating oil. Utility Model Content

[0005] The purpose of this invention is to provide a self-circulating lubrication structure for machine tool guideways to solve the problems mentioned in the background art.

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

[0007] A self-circulating lubrication structure for machine tool guideways includes a base plate, a machine tool guideway fixed to the center of the top surface of the base plate, a movable seat mounted on the machine tool guideway, and further includes:

[0008] A recycling mechanism for recycling lubricating oil includes two guide channels and two collection boxes. The two guide channels are both opened on the top surface of the base plate and are respectively located on the front and rear sides of the machine tool guide rail. The two collection boxes are respectively fixed on the left and right sides of the base plate, and the left and right ends of the guide channels are respectively connected to the collection boxes on both sides.

[0009] A coating mechanism for evenly applying lubricating oil includes mounting plates fixed at the four corners of the movable seat. Movable columns are slidably connected to the mounting plates. A connecting block is fixed to the top of the movable column. An oiling brush is fixed to one end of the connecting block near the adjacent corner of the movable seat. The bottom end of the oiling brush is in intermittent contact with the machine tool guide rail.

[0010] Preferably, the recycling mechanism further includes two circulation pumps fixed to the rear end of the top surface of the substrate, and the inlet of the circulation pump is connected to the collection box on the same side through a recycling pipe;

[0011] Preferably, the top surface of the collection box is hinged with a cover, and a filter plate is slidably inserted into the collection box;

[0012] These two features, through the cooperation of the circulation pump and the recovery pipe, can pressurize and deliver the lubricating oil recovered in the collection box to the coating mechanism, forming a closed-loop circulation system for the lubricating oil. This improves the level of automation and the sustainability of the lubrication system. Furthermore, the sealing cap and filter plate ensure the cleanliness of the circulating lubricating oil, preventing impurities from causing wear on the machine tool guide rails and moving seats, and extending the service life of the equipment.

[0013] Preferably, the top of the oiling brush is equipped with an oil delivery pipe, and two adjacent oil delivery pipes are connected to the outlet of the circulating pump on the same side through a T-joint.

[0014] This setting precisely delivers the lubricating oil output from the circulating pump to the oiling brush, ensuring that the oiling brush continuously receives lubricating oil during the application process. At the same time, the length of the oil delivery pipe is adapted to the range of motion of the movable seat, ensuring the continuity of lubrication operations when the movable seat moves.

[0015] Preferably, the mounting plate is inverted L-shaped, and a driven shaft is rotatably connected to the vertical plate of the mounting plate. A cam is fixed to the outer wall of the driven shaft, and the cam cooperates with the movable column.

[0016] Preferably, a collar is fixed to the outer side wall of the movable column near the bottom end, and a spring sleeved on the outside of the movable column is installed between the collar and the horizontal plate of the mounting plate.

[0017] Preferably, a drive shaft is rotatably connected to the vertical plate of the mounting plate, and the drive shaft and the driven shaft are connected by belt drive.

[0018] Preferably, a gear is fixed to the outer wall of the drive shaft, and racks are fixed to the top surface of the base plate on both the front and rear sides of the machine tool guide rail, with the gear meshing with the racks on the same side;

[0019] These four settings utilize an inverted L-shaped mounting plate and a sliding connection between the cam and the movable column. The spring elastic reset allows the oiling brush to intermittently contact the guide rail for oiling, preventing over-applying and brush wear. With the help of the drive shaft, driven shaft, and belt transmission structure, combined with the meshing drive of gears and racks, the oiling action can be synchronized with the movement of the movable seat without additional power. This ensures lubrication while reducing energy consumption, vibration, and noise, and improving the smoothness and reliability of the mechanism's operation.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model, through the cooperation of components such as the guide channel, collection box, circulation pump and recycling pipe in the recycling mechanism, collects excess lubricating oil on the machine tool guide rail and pressurizes and delivers it to the coating mechanism, forming a closed-loop circulation system. It eliminates the need for frequent manual addition of lubricating oil, significantly reduces the cost of lubricating oil use, and also reduces the generation of waste, making it more environmentally friendly.

[0022] 2. This utility model, through the intermittent contact design between the oiling brush and the machine tool guide rail in the coating mechanism, combined with the functions of components such as cams, movable columns, and springs, can achieve uniform application of lubricating oil when the movable seat moves. This avoids the problem of excessive application of lubricating oil or brush wear caused by continuous contact of the oiling brush with the guide rail. While ensuring the lubrication effect, it optimizes the lubrication efficiency and reduces the waste of lubricating oil. Attached Figure Description

[0033] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] Please see Figures 1-4 The present invention provides the following technical solution:

[0035] The machine tool guide rail self-circulating lubrication structure includes a base plate 100, a machine tool guide rail 200 fixed in the center of the top surface of the base plate 100, a movable seat 300 mounted on the machine tool guide rail 200, and further includes:

[0036] The recycling mechanism 400 for recycling lubricating oil includes two guide channels 401 and two collection boxes 402. The two guide channels 401 are both opened on the top surface of the base plate 100 and are located on the front and rear sides of the machine tool guide rail 200, respectively. The two collection boxes 402 are fixed on the left and right sides of the base plate 100, respectively. By setting the guide channels 401 and collection boxes 402 of the recycling mechanism 400, the left and right ends of the guide channels 401 are connected to the collection boxes 402 on both sides, respectively. Excess lubricating oil on the machine tool guide rail 200 can be collected into the collection boxes 402 through the guide channels 401, so as to achieve the initial recycling of lubricating oil.

[0037] A coating mechanism 500 for evenly applying lubricating oil includes mounting plates 501 fixed at the four corners of the movable seat 300. A movable column 504 is slidably connected to the mounting plate 501. A connecting block 507 is fixed to the top of the movable column 504. An oiling brush 508 is fixed to one end of the connecting block 507 near the adjacent corner of the movable seat 300. The bottom end of the oiling brush 508 intermittently contacts the machine tool guide rail 200. The intermittent contact between the oiling brush 508 of the coating mechanism 500 and the machine tool guide rail 200 allows for even application of lubricating oil as the movable seat 300 moves, reducing lubricating oil waste and improving lubrication efficiency.

[0038] In this embodiment, please refer to Figures 1-4 The recycling mechanism 400 also includes two circulation pumps 406 fixed to the rear end of the top surface of the substrate 100. The inlet of the circulation pump 406 is connected to the collection box 402 on the same side through a recycling pipe 405. The lubricating oil recovered in the collection box 402 can be pressurized and transported to the coating mechanism 500 through the circulation pump 406 to form a closed-loop circulation system of lubricating oil. There is no need for frequent manual addition of lubricating oil, which improves the degree of automation and the sustainability of the lubrication system.

[0039] Specifically, a cover 403 is hinged to the top surface of the collection box 402 to prevent debris from falling into the collection box 402 and contaminating the lubricating oil. A filter plate 404 is slidably inserted into the collection box 402 to filter and recover impurities in the lubricating oil, ensuring the cleanliness of the circulating lubricating oil, avoiding wear on the machine tool guide rail 200 and movable seat 300 caused by impurities, and extending the service life of the equipment.

[0040] In this embodiment, please refer to Figures 1-4 The top of the oiling brush 508 is equipped with an oil supply pipe 509. Two adjacent oil supply pipes 509 are connected to the outlet of the circulating pump 406 on the same side through a T-joint. The oil supply pipe 509 needs to be long enough to be used when the movable seat 300 moves.

[0041] In this embodiment, please refer to Figures 1-3 The mounting plate 501 is inverted L-shaped. A driven shaft 502 is rotatably connected to the vertical plate of the mounting plate 501. A cam 503 is fixed on the outer wall of the driven shaft 502. The cam 503 cooperates with the movable column 504. When the driven shaft 502 rotates, the cam 503 pushes the movable column 504 to slide up and down, so that the oiling brush 508 can achieve intermittent action of contacting the machine tool guide rail 200 to apply oil and disengaging from the machine tool guide rail 200 to lift up. This avoids the oiling brush 508 continuously contacting the guide rail, which would cause excessive application of lubricating oil or wear of the brush, thus optimizing the lubrication effect and component life.

[0042] Specifically, a collar 505 is fixed near the bottom of the outer wall of the movable column 504. A spring 506 is installed between the collar 505 and the horizontal plate of the mounting plate 501, which is sleeved on the movable column 504. The elastic force of the spring 506 can make the movable column 504 automatically reset after the cam 503 rotates, ensuring that the oiling brush 508 stably contacts or separates from the machine tool guide rail 200. At the same time, it buffers the impact between the cam 503 and the movable column 504, reduces mechanical vibration and noise, and improves the smoothness of the mechanism operation.

[0043] Furthermore, a drive shaft 510 is rotatably connected to the vertical plate of the mounting plate 501. The drive shaft 510 and the driven shaft 502 are connected by a belt 511. The transmission method is simple in structure and easy to maintain. Moreover, the belt 511 has a certain elasticity, which can adapt to installation errors and ensure the reliability of power transmission.

[0044] In addition, a gear 512 is fixed to the outer wall of the drive shaft 510, and racks 513 are fixed to both the front and rear sides of the machine tool guide rail 200 on the top surface of the base plate 100. The gear 512 meshes with the rack 513 on the same side, and the coating mechanism 500 is passively driven without the need for an additional power source, saving energy. It also makes the movement of the oil brush 508 synchronize with the movement of the movable seat 300, ensuring that the guide rail is lubricated in real time during the movement.

[0045] Finally, it should be noted that the movable seat 300 and circulating pump 406 involved in this utility model are all general standard parts or parts known to those skilled in the art. Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components and the matching controller and power supply, are connected by wires. The specific connection method should refer to the working principle in this utility model. The electrical connection between each electrical component is completed in the order of operation. The detailed connection method is a technology known in the art.

[0046] In use, the self-circulating lubrication structure of the machine tool guide rail of this utility model has the machine tool guide rail 200 fixed in the middle of the base plate 100, the movable seat 300 installed on the guide rail and can move back and forth along the guide rail, the filter plate 404 installed in the collection box 402, the cover 403 closed to prevent debris from falling in, the circulation pump 406 connected to the collection box 402 through the recovery pipe 405, the collection box initially stores a certain amount of lubricating oil, and the cover 403 can also be opened to add lubricating oil, the mounting plate 501 fixed at the four corners of the movable seat 300 to avoid interfering with the operation of the movable seat 300;

[0047] When the movable seat 300 moves along the machine tool guide rail 200, the gear 512 on the mounting plate 501 meshes with the rack 513 on the base plate 100, driving the drive shaft 510 to rotate. The drive shaft 510 is transmitted to the driven shaft 502 through the belt 511, driving the cam 503 to rotate. When the cam 503 rotates, its contour pushes the movable column 504 to move upward against the elastic force of the spring 506, causing the oiling brush 508 to disengage from the machine tool guide rail 200. After the cam 503 rotates past the protrusion, the spring 506 resets the movable column 504, and the oiling brush 508 descends to contact the machine tool guide rail 200 and applies lubricating oil, avoiding continuous contact that could lead to wear or waste of lubricating oil.

[0048] Excess lubricating oil on the machine tool guide rail 200 flows into the guide groove 401 on the top surface of the base plate 100 under the action of gravity. It flows into the collection boxes 402 on both sides along the left and right ends of the guide groove 401. The circulation pump 406 pressurizes the lubricating oil in the collection box 402 and delivers it to the oil supply pipe 509 through the recovery pipe 405. It is then distributed to each oiling brush 508 through the three-way connector to ensure that the oiling brush 508 is continuously supplied with oil.

[0049] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
