Description

Technical Field

[0001] This invention belongs to the field of guide rail maintenance technology, specifically an auxiliary lubrication device for machine tool guide rails. Background Technology

[0002] The guide rail is a crucial component of a machine tool, used to support and guide moving parts along a predetermined path for machining components. Therefore, the design, manufacturing, and maintenance of the guide rail are all very important.

[0003] To ensure the smooth movement of components on the guide rail, it is generally necessary to apply lubricating oil regularly. However, existing technology typically requires workers to manually clean the old lubricating oil from the guide rail and manually apply new lubricating oil. Since the guide rail is located inside the machine tool, workers need to extend their bodies into the machine tool. This operation not only compromises the safety of the operators but also significantly prolongs the manual maintenance time. Therefore, we provide an auxiliary lubrication device for machine tool guide rails. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides an auxiliary lubrication device for machine tool guideways, which solves the problem that it is very inconvenient for operators to manually clean and replace the lubricating oil on the guideways by having to put their bodies into the machine tool, thus greatly increasing the maintenance time.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary lubrication device for machine tool guideways, comprising a machine tool guideway and a central bar placed on top of the machine tool guideway, and further comprising;

Several expansion blocks are movably installed circumferentially at equal angles inside the spraying pipe. A guide block is fixedly installed at the bottom of the water box. The top of the expansion block abuts against the bottom of the guide block through a guide rod. Several expansion blocks arranged circumferentially at equal angles are fixedly connected by two limiting rings distributed vertically. Spraying holes are equidistantly arranged on the outer periphery of the expansion block and the spraying pipe. The expansion block is connected to the inside of the spraying pipe. The bottom of the lower limiting ring is elastically connected to the inside of the spraying pipe through a spring.

[0015] Preferably, the spring is set on the outer periphery of the oil pipe, and a trapezoidal block is movably installed inside the oil storage box. The trapezoidal block divides the interior of the oil storage box into two chambers. The oil pipe passes through the trapezoidal block and is connected to the chamber away from the threaded rod. Several holes are equidistantly arranged on the outer side of the protective shell, and the outer side of the holes contacts the protective shell.

[0016] Preferably, the power assembly includes a motor fixed to the top of the center bar, the output shaft of the motor is driven by a second gear, the bottom of the motor is movably mounted with a first gear, the second gear is driven by a first chain, the first gear is driven by a second chain, the output shaft of the motor is driven by a guide rod, and the bottom of the guide rod is movably mounted with a push rod.

[0017] Preferably, gear one meshes with gear two, chain one and chain two are respectively connected to two spray pipes for transmission, the middle part of the push rod is hollow, and the bottom of the guide rod is movable inside the push rod.

[0018] Preferably, the oil injection assembly includes a limiting frame fixed to the top of two protective shells. A double-layer corrugated pipe is fixed inside the limiting frame. Two one-way valves are symmetrically arranged on the top of the double-layer corrugated pipe. The interior of the double-layer corrugated pipe is connected to the interior of the limiting frame through two symmetrically arranged one-way valves. A straight rod is fixed inside the double-layer corrugated pipe. The straight rod passes through the side of the double-layer corrugated pipe and is fixedly connected to the push rod. A transport pipe is connected to each side of the limiting frame.

[0019] Preferably, the double-layer corrugated pipe restricts the axial movement of the push rod by a straight rod, the output shaft of the motor drives the guide rod to rotate and push the push rod to move back and forth, the inside of the motor is divided into two independent inner cavities by a metal partition, the straight rod is fixed to the metal partition, and the push rod pushes the metal partition to reciprocate and squeeze the inside of the double-layer corrugated pipe through the straight rod.

[0020] Preferably, the two one-way valves are connected to the two inner cavities inside the double-layer corrugated pipe, and the transport pipe is connected to the interior of the two water boxes.

[0021] Preferably, the top of the limiting frame is fixedly connected to the bottom of the motor, the bottom of the limiting frame is made of plastic, and the inside of the double-layer corrugated pipe is filled with cleaning agent.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This invention utilizes a combination of cleaning components and machine tool guide rails. A spray pipe drives an extension block to rotate, spraying cleaning agent through spray nozzles onto the side of the machine tool guide rail in a rotating motion. The rotation of the extension block causes a guide rod to slide along the bottom of the guide block and move up and down in a closed-loop, wave-like trajectory, thereby increasing the spraying range of the cleaning agent. When the cleaning agent comes into contact with oil stains on the side of the machine tool guide rail, it dissolves the oil and flows downwards into the protective shell. If the oil stains contain fine iron filings from machine tool processing, or if the oil stains are firmly adhered and the cleaning agent cannot dissolve them in time, a rubber plate will block these foreign objects. Finally, a sponge wipes away any remaining cleaning agent on the side of the machine tool guide rail, ensuring that new lubricating oil is not dissolved by the residual cleaning agent. During the cleaning process, the operator only needs to manually slide the device to clean the oil stains on the side of the machine tool guide rail, thus improving the efficiency of the device.

[0024] This invention, through the coordinated arrangement of a lubrication assembly and machine tool guide rails, utilizes a rotating threaded rod to force a guide plate downwards. This guide plate is then pushed to one side by the inclined surface of a trapezoidal block, squeezing the lubricating oil from the inner cavity of the oil reservoir. The oil then contacts a cotton strip through a groove on its side. After lubrication and continuous soaking of the cotton strip, excess lubricating oil seeps out onto the surface of the cotton strip, allowing it to contact the side of the machine tool guide rail. Since the device continuously moves around the outer periphery of the guide rail, the cotton strip does not remain on the same part of the guide rail side for too long. This ensures that the amount of lubricating oil on each part of the guide rail side is as uniform as possible, further reducing operator workload.

[0025] This invention, through the coordinated arrangement of an oil injection component and a cleaning component, ensures that when the right chamber inside the double-layer corrugated pipe is compressed, the cleaning agent inside enters the limiting frame through the right one-way valve and is ultimately supplied to the spray pipe. When the left chamber is compressed, the cleaning agent in that section enters the limiting frame through the left one-way valve. This allows the limiting frame to continuously supply cleaning agent to the spray pipe through the transport pipe, thereby ensuring that the spraying component can continuously spray cleaning agent onto the side of the machine tool guide rail during operation and improving the smoothness of the device's operation. When the right chamber is compressed, the left side is under negative pressure, forcing the left one-way valve to open, allowing external air to enter the left side through the one-way valve. This ensures that when the left chamber is compressed, the cleaning agent inside can be quickly discharged, simultaneously improving the efficiency of the device's operation.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] like Figures 1 to 13 As shown, the present invention provides an auxiliary lubrication device for machine tool guideways, including a machine tool guideway 1 and a central bar 3 placed on top of the machine tool guideway 1, and further comprising;

[0042] Two cleaning components 4 are symmetrically arranged at both ends of the bottom of the middle bar 3;

[0043] The cleaning component 4 includes a protective shell 41 fixedly connected to the bottom of the middle bar 3. Two spraying components 42 are symmetrically arranged inside the protective shell 41. A rubber plate 47 is fixedly installed inside the protective shell 41 between the two spraying components 42.

[0044] The spraying assembly 42 includes a water tank 421 fixedly connected to the top of the protective shell 41. A spraying pipe 422 is movably installed inside the water tank 421. Several expansion blocks 423 are movably installed circumferentially at equal angles inside the spraying pipe 422. A guide block 425 is fixedly installed at the bottom of the water tank 421. The top of the expansion block 423 abuts against the bottom of the guide block 425 through a guide rod 424. Several expansion blocks 423 arranged circumferentially at equal angles are fixedly connected by two limiting rings 427 distributed vertically. Spray holes 426 are equidistantly arranged on the outer periphery of the expansion block 423 and the spraying pipe 422. The expansion block 423 is connected to the interior of the spraying pipe 422. The bottom of the lower limiting ring 427 is elastically connected to the interior of the spraying pipe 422 through a spring 428.

[0045] The cleaning assembly 4 also includes a baffle 44 hinged to the inner wall of the protective shell 41. The hinge of the baffle 44 and the protective shell 41 is elastically connected to the inner wall of the protective shell 41 by two springs 45. The outer side of the baffle 44 is elastically connected to the inner wall of the protective shell 41 by springs 45. Two spray pipes 422 located on the same protective shell 41 are connected by a chain 43. A sponge 48 is fixed inside the protective shell 41 on the side away from the baffle 44.

[0046] Two lubrication components 5 are respectively provided on the sides of the two protective shells 41. The lubrication components 5 are used to apply lubricating oil to the sides of the machine tool guide rail 1.

[0047] The power assembly 2 is located at the top of the middle bar 3 and is used to drive the spray pipe 422 to rotate.

[0048] The oiling assembly 6, which is located on top of the two cleaning assemblies 4, is driven by the power assembly 2 to inject cleaning agent into the interior of each water box 421.

[0049] The interior of the water box 421 is connected to the interior of the spraying assembly 42. The bottom of the guide block 425 is in a closed-loop wave shape. The sides of the baffle 44, rubber plate 47 and sponge 48 are adapted to the sides of the machine tool guide rail 1.

[0050] Using the above solution: when the machine tool guide rail 1 needs to be cleaned, the power unit 2 can be started;

[0051] The power unit 2 drives one of the spray pipes 422 of the two cleaning components 4 to rotate, and the spray pipe 422 drives the other spray pipe 422 to rotate. At this time, both cleaning components 4 enter the working state.

[0052] As the spray pipe 422 rotates, the power unit 2 also drives the oil injection unit 6 to inject cleaning agent into the water box 421. The cleaning agent eventually enters the spray pipe 422. However, since the spray pipe 422 is rotating, it drives several extension blocks 423 to rotate synchronously. At this time, the cleaning agent is sprayed onto the side of the machine tool guide rail 1 through the spray hole 426 in a rotating posture.

[0053] It is important to note that the guide block 425 is in a fixed state, while the spring 428 continuously supports the expansion block 423 to rise through the lower limiting ring 427. The expansion block 423 pushes the guide rod 424 to press against the bottom of the guide block 425. When the expansion block 423 rotates, it drives the guide rod 424 to slide at the bottom of the guide block 425 and move up and down through a closed-loop wave-like trajectory, thereby increasing the spraying range of the cleaning agent. When the cleaning agent comes into contact with the oil stains on the side of the machine tool guide rail 1, it can dissolve them and flow downwards. The side of the protective shell 41 is in contact with the side of the machine tool guide rail 1, which allows the liquid after the cleaning agent and oil stains are dissolved to flow into the interior of the protective shell 41.

[0054] When the oil stains contain fine iron filings from machine tool processing, or when the oil stains are firmly adhered and the cleaning agent cannot dissolve them in time, the rubber sheet 47 will block these foreign objects. Figure 8 The spray pipe 422 shown in the figure will be driven by the power unit 2 to rotate counterclockwise and spray the cleaning agent onto the side of the machine tool guide rail 1 and the side of the rubber plate 47 in sequence, thereby avoiding the cleaning agent from spilling outward through the gap between the baffle 44 and the machine tool guide rail 1 and causing waste.

[0055] The oil stains scraped off by the rubber plate 47 are dissolved, and the iron filings encased in it will fall into the interior of the machine tool guide rail 1, thereby reducing the need for subsequent cleaning of the rubber plate 47. The toughness of the rubber plate 47 allows it to better fit the side of the machine tool guide rail 1. After the rubber plate 47 scrapes off the oil stains, the oil stains that are still not cleaned from the side of the machine tool guide rail 1 will pass through the second spray component 42, and then undergo the cleaning agent dissolution process again. Finally, the sponge 48 wipes off the residual cleaning agent from the side of the machine tool guide rail 1 to ensure that when new lubricating oil is applied later, it will not be dissolved by the cleaning agent remaining on the side of the machine tool guide rail 1.

[0056] Furthermore, when the oil stains attached to the side of the machine tool guide rail 1 contain too many impurities, causing the side of the machine tool guide rail 1 to no longer be flat, the baffle 44 will be tilted when it passes over these impurities, thereby reducing the amount of cleaning agent sprayed to the outside of the protective shell 41. Then, the second spring 45 will push the baffle 44 to its initial position, and the spring plate 46 will always support the side of the baffle 44 to ensure that it is tilted, thereby passing over the impurities better. Similarly, it avoids that impurities and oil stains are blocked too much on the outside of the baffle 44, further improving the device's ability to clean oil stains, while also reducing the subsequent cleaning work of the cleaning component 4.

[0057] During the cleaning process, the operator only needs to manually slide the device to clean the oil stains on the side of the machine tool guide rail 1, thereby improving the efficiency of the device.

[0058] like Figures 1 to 4 , Figure 13 As shown, the lubrication assembly 5 includes an oil reservoir 51 fixed to the side of the protective shell 41. A threaded rod 53 is movably installed inside the oil reservoir 51. A guide plate 54 is threaded on the outer periphery of the threaded rod 53. The inside of the oil reservoir 51 is pushed by a spring 3 56 to contact the inclined surface of the trapezoidal block 55 with the guide plate 54. An oil pipe 57 is fixedly passed through the side of the oil reservoir 51. The threaded rod 53 is connected to the spray pipe 422 via a chain 4 58.

[0059] Spring 56 is sleeved on the outer periphery of oil pipe 57. Trapezoidal block 55 is movably installed inside oil reservoir 51. Trapezoidal block 55 divides the interior of oil reservoir 51 into two chambers. Oil pipe 57 passes through trapezoidal block 55 and is connected to the chamber away from threaded rod 53. Several holes are equidistantly arranged on the outer side of protective shell 41. The outer side of the holes contacts protective shell 41.

[0060] Using the above solution: A nut is provided on the outside of the oil pipe 57. After removing the nut, new lubricating oil can be injected into the inner cavity of the oil reservoir 51 away from the threaded rod 53 through the oil pipe 57.

[0061] When the device is working, the spray pipe 422 drives the threaded rod 53 to rotate via the chain 4 58. Since the trapezoidal block 55 is always in contact with the side of the guide plate 54, the rotation of the threaded rod 53 will force the guide plate 54 to descend. The length of the guide plate 54 is fixed vertical, but the side of the trapezoidal block 55 near the guide plate 54 is inclined. During the descent of the guide plate 54, it will push the trapezoidal block 55 to one side through the inclined surface of the trapezoidal block 55, thereby squeezing the lubricating oil in the inner cavity of the oil storage box 51. This allows the lubricating oil to contact the cotton strip 52 through the groove on the side of the oil storage box 51. After lubrication and continuous soaking of the cotton strip 52, the excess lubricating oil will seep out to the surface of the cotton strip 52, thus allowing the lubricating oil to contact the side of the machine tool guide rail 1. Since the device is constantly moving around the outer periphery of the machine tool guide rail 1, this prevents the cotton strip 52 from staying in the same part of the side of the machine tool guide rail 1 for too long, thereby ensuring that the amount of lubricating oil on each part of the side of the machine tool guide rail 1 is the same as much as possible, and further reducing the working time of the operator.

[0062] like Figure 1 , Figures 9 to 12 As shown, the power assembly 2 includes a motor 21 fixed to the top of the center bar 3. The output shaft of the motor 21 is driven by a gear 23. A gear 22 is movably mounted on the bottom of the motor 21. A chain 24 is driven by the gear 23. A chain 25 is driven by the gear 22. A guide rod 26 is driven by the output shaft of the motor 21. A push rod 27 is movably mounted on the bottom of the guide rod 26.

[0063] Gear 1 22 meshes with gear 23, chain 1 24 and chain 2 25 are respectively connected to the two spray pipes 422 for transmission, the middle part of the push rod 27 is hollow, and the bottom of the guide rod 26 moves inside the push rod 27.

[0064] The double-layer corrugated pipe 62 restricts the axial movement of the push rod 27 by the straight rod 64. The output shaft of the motor 21 drives the guide rod 26 to rotate and pushes the push rod 27 to move back and forth. The interior of the motor 21 is divided into two independent inner cavities by a metal partition. The straight rod 64 is fixed on the metal partition. The push rod 27 pushes the metal partition to reciprocate and squeeze the interior of the double-layer corrugated pipe 62 through the straight rod 64.

[0065] Using the above scheme: After motor 21 starts, it drives gear 23 and gear 22 to rotate simultaneously via its output shaft. Gear 23 meshes with gear 22, which causes gear 22 to rotate the spray pipe 422 via chain 25 in the opposite direction to the rotation of the other spray pipe 422 by gear 23 via chain 24. Figure 8The power assembly 2 and the two spray pipes 422 shown in the diagram rotate counterclockwise on the left and clockwise on the right, so that both spray assemblies 42 are in normal working condition. The cleaning agent sprayed by the two spray pipes 422 will not leak out through the gap between the baffle 44 and the side of the machine tool guide rail 1, thus avoiding waste of cleaning agent.

[0066] The straight rod 64 passes through the side of the double-layer corrugated pipe 62 and is fixed vertically to the side of the metal partition. This allows the straight rod 64 and the push rod 27 to move only horizontally. The output shaft of the motor 21 will also drive the guide rod 26 to rotate. The bottom of the guide rod 26 is also movable in the hollow part of the push rod 27. This allows the rotation of the guide rod 26 to drive the push rod 27 to move horizontally back and forth and squeeze the inside of the double-layer corrugated pipe 62. At this time, the oil injection component 6 can normally squeeze the cleaning agent into the inside of the spray pipe 422, thereby ensuring the smooth operation of the device.

[0067] like Figures 1 to 4 and Figure 12 As shown, the oil injection assembly 6 includes a limiting frame 61 fixed to the top of two protective shells 41. A double-layer bellows 62 is fixed inside the limiting frame 61. Two one-way valves 66 are symmetrically arranged on the top of the double-layer bellows 62. The interior of the double-layer bellows 62 is connected to the interior of the limiting frame 61 through two symmetrically arranged one-way valves 65. A straight rod 64 is fixed inside the double-layer bellows 62. The straight rod 64 passes through the side of the double-layer bellows 62 and is fixedly connected to the push rod 27. A transport pipe 63 is connected to each side of the limiting frame 61.

[0068] Two one-way valves 65 and 66 are respectively connected to the two inner cavities inside the double-layer corrugated pipe 62, and the transport pipe 63 is connected to the interior of the two water boxes 421.

[0069] The top of the limiting frame 61 is fixedly connected to the bottom of the motor 21. The bottom of the limiting frame 61 is made of plastic, and the inside of the double-layer corrugated pipe 62 is filled with cleaning agent.

[0070] Using the above scheme: the push rod 27 moves the metal partition back and forth through the straight rod 64, so that the two chambers inside the double-layer corrugated pipe 62 can be squeezed back and forth;

[0071] like Figure 11The double-walled bellows 62 and the one-way valve 65 shown in the diagram allow the cleaning agent inside the right chamber of the double-walled bellows 62 to enter the interior of the limiting frame 61 through the right one-way valve 65 when the right chamber is squeezed. The cleaning agent is then delivered to the spray pipe 422 through the transport pipe 63. When the left chamber is squeezed, the cleaning agent in that chamber will enter the interior of the limiting frame 61 through the left one-way valve 65. This ensures that the limiting frame 61 can always deliver the cleaning agent to the interior of the spray pipe 422 through the transport pipe 63, thereby ensuring that the spraying assembly 42 can continuously spray the cleaning agent onto the side of the machine tool guide rail 1 during operation and improving the smoothness of the device's operation.

[0072] For example Figure 2 The limiting frame 61 and the two one-way valves 66 shown in the diagram create a negative pressure on the left side when the right chamber is squeezed, which forces the left one-way valve 66 to open. External air enters the left side through the one-way valve 66 on that side, thus ensuring that the cleaning agent inside the left chamber can be quickly discharged when it is squeezed, and at the same time improving the efficiency of the device.

[0073] Working principle and usage process of this invention:

[0074] When the machine tool guide rail 1 needs to be cleaned, a nut is provided on the outside of the oil pipe 57. After removing the nut, new lubricating oil can be injected into the inner cavity of the oil reservoir 51 away from the threaded rod 53 through the oil pipe 57.

[0075] Then the motor 21 is started, and its output shaft drives gear 23 and gear 1 22 to rotate simultaneously. Gear 23 meshes with gear 1 22, which makes gear 1 22 rotate the spray pipe 422 in the opposite direction to the direction that gear 2 23 drives the other spray pipe 422 to rotate ...1 22 drives in the opposite direction to the direction that gear 2 23 drives in the opposite direction to the direction that gear 1 24 drives the other spray pipe 422 to rotate.

[0076] The output shaft of motor 21 drives guide rod 26 to rotate, and drives push rod 27 to move horizontally back and forth. Push rod 27 moves metal partition back and forth through straight rod 64, and the two chambers inside double-layer corrugated pipe 62 can be squeezed back and forth.

[0077] When the right chamber is squeezed, the cleaning agent inside it enters the interior of the limiting frame 61 through the right one-way valve 65, and is finally injected into the spray pipe 422 through the transport pipe 63. When the left chamber is squeezed, the cleaning agent in this part will enter the interior of the limiting frame 61 through the left one-way valve 65. The limiting frame 61 can always inject cleaning agent into the interior of the spray pipe 422 through the transport pipe 63.

[0078] The spray pipe 422 drives several extension blocks 423 to rotate synchronously. The cleaning agent is sprayed onto the side of the machine tool guide rail 1 through the spray hole 426 in a rotating posture. The guide block 425 is fixed. The spring 428 supports the extension block 423 to rise through the lower limit ring 427. The extension block 423 pushes the guide rod 424 to stick to the bottom of the guide block 425. When the extension block 423 rotates, it drives the guide rod 424 to slide on the bottom of the guide block 425 and move up and down through a closed-loop wave-shaped trajectory. The side of the protective shell 41 contacts the side of the machine tool guide rail 1. The liquid after the cleaning agent and oil stains are dissolved will flow into the interior of the protective shell 41.

[0079] After the rubber plate 47 scrapes against the oil stains, the oil stains that cannot be cleaned from the side of the machine tool guide rail 1 will pass through the second spray component 42 to dissolve the cleaning agent again. Finally, the sponge 48 will wipe away the residual cleaning agent from the side of the machine tool guide rail 1.

[0080] The spray pipe 422 drives the threaded rod 53 to rotate via the chain 4 58. The rotation of the threaded rod 53 will force the guide plate 54 to descend. It will push the trapezoidal block 55 to one side through the inclined surface of the trapezoidal block 55, thereby squeezing the lubricating oil in the inner cavity of the oil reservoir 51. This will cause the lubricating oil to contact the cotton strip 52 through the groove on the side of the oil reservoir 51. After lubrication, the cotton strip 52 will be continuously soaked. The excess lubricating oil will seep out to the surface of the cotton strip 52, thereby making the lubricating oil applied to the side of the machine tool guide rail 1.
