Description

Technical Field

[0001] This utility model relates to the field of machine tools, and in particular to a novel transmission lubrication supplementation device for CNC machine tools. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system logically processes programs defined by control codes or other symbolic instructions, decodes them, represents them with coded numbers, and inputs them into the CNC device via an information carrier. The lubrication system of a CNC machine tool plays a crucial role in the overall machine tool design. It not only lubricates but also cools the machine, reducing the impact of thermal deformation on machining accuracy. The design, debugging, and maintenance of the lubrication system are of paramount importance for ensuring machining accuracy and extending the machine tool's service life.

[0003] However, in the existing technology, oil pumps are usually used to directly deliver lubricating grease or lubricating oil to the transmission parts of CNC machine tools to achieve lubrication. The oil pump needs to be in operation for a long time, which can easily lead to a shortened service life of the oil pump. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a novel transmission lubrication replenishment device for CNC machine tools. To solve the above technical problem, the technical solution of this utility model is as follows:

[0005] A novel transmission lubrication replenishment device for CNC machine tools includes a grease storage tank. A partition plate is fixedly installed on the inner side of the grease storage tank. A storage bin and a feeding bin are respectively provided on both sides of the partition plate. An oil pump is installed on the inner side of the feeding bin. A temporary replenishment unit is installed at the output end of the oil pump. A conveying pipe is installed at the upper end of the temporary replenishment unit.

[0006] The temporary storage and replenishment unit includes a temporary storage box. Two push plates are slidably connected to the inner side of the temporary storage box. A sealing strip is provided between the two push plates and the temporary storage box. Multiple support springs are provided on one side of the push plates. A guide rod is installed on the inner side of the support springs. Guide frames are fixedly installed on both sides of the temporary storage box. A first electrical contact metal piece is fixedly installed on one end corner of one of the guide frames, and a second electrical contact metal piece is fixedly installed on one end of one of the guide rods.

[0007] Preferably, a level gauge is fixedly installed on the inner side of the storage bin, which is located on the inner wall of the grease storage tank, and a collecting cone seat is fixedly installed at the bottom of the grease storage tank, with the storage bin and the collecting cone seat being connected in a through manner.

[0008] Preferably, the temporary storage box is fixedly connected to the grease storage box, the upper end of the temporary storage box is fixedly connected to the conveying pipe, the output end of the oil pump is connected to the conveying pipe through the temporary storage box, and the input end of the oil pump passes through the partition plate and is inserted into the inner side of the collecting cone seat.

[0009] Preferably, an injection pipe is fixedly installed on the front end face of the oil storage box, the oil storage box is connected to the injection pipe, a sealing cover is fixedly installed on the upper end of the oil storage box, a booster pump is fixedly installed on one end corner of the sealing cover, and the output end of the booster pump passes through the sealing cover and is inserted into the inside of the storage bin.

[0010] Preferably, the plurality of guide rods pass through the guide frame, the injection tube and the support spring and are fixedly connected to the push plate. The temporary storage box is connected to both push plates by a sealing strip. The two temporary storage boxes, the sealing strip and the guide frame are symmetrically installed relative to the middle of the temporary storage box.

[0011] Preferably, the push plate is connected to the guide frame by multiple support springs, and the first electrically conductive metal piece is sleeved on the outside of one of the guide rods and in insulating contact with one of the guide rods.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Fix the grease storage box to the outside of the CNC machine tool, so that the upper end of the storage box is connected to the transmission part of the CNC machine tool through the material conveying pipe. Lubricating grease is injected into the inside of the storage bin through the injection pipe. The oil pump draws the lubricating grease from the inside of the collecting cone seat and injects it into the inside of the storage box for temporary storage. At this time, the two push plates installed symmetrically in the storage box slide in opposite directions under pressure when the lubricating grease is injected, and compress the support spring. When the first and second electrical contact metal plates separate, the oil pump is de-energized after a delay. Then, the two push plates can move towards each other under the elastic support of multiple support springs and continuously pressurize the lubricating grease, so that the lubricating grease can be continuously delivered to the transmission part of the CNC machine tool through the material conveying pipe, realizing a continuous and stable lubricating grease replenishment operation.

[0014] 2. Under the support of the support spring, the push plate drives the second energized metal plate to contact the first energized metal plate through the guide rod, thereby starting the oil pump and realizing the repeated extraction and delivery of lubricating grease. This facilitates the automatic replenishment of lubricating grease to the transmission parts of the CNC machine tool, reduces the running time of the oil pump, and extends the service life of the oil pump. At the same time, the booster pump injects air into the inside of the storage bin, so that the inside of the storage bin can maintain a full state of lubricating grease inside the collecting cone seat after being pressurized.

The storage bin 8 and the collecting cone seat 11 are connected in a through manner. The input end of the oil pump 10 passes through the partition plate 7 and is inserted into the inner side of the collecting cone seat 11, so that the oil pump 10 draws lubricating grease from the inner side of the collecting cone seat 11 under the support of the partition plate 7.

[0024] A filling pipe 3 is fixedly installed on the front end of the grease storage tank 1. The grease storage tank 1 is connected to the filling pipe 3.

The output end of the booster pump 4 passes through the sealing cover 2 and is inserted into the inside of the storage silo 8. The booster pump 4 injects air into the inside of the storage silo 8, so that the inside of the storage silo 8 can maintain a full state of lubricating grease inside the collecting cone seat 11 after being pressurized.

[0025] As a preferred technical solution in this embodiment, such as Figures 2 to 5 As shown, a temporary feeding unit 12 is installed at the output end of the oil pump 10. A conveying pipe 5 is installed at the upper end of the temporary feeding unit 12. The temporary feeding unit 12 includes a temporary storage box 13, which is fixedly connected to the oil storage box 1. The upper end of the temporary storage box 13 is fixedly connected to the conveying pipe 5. The output end of the oil pump 10 and the conveying pipe 5 are connected through the temporary storage box 13. Two push plates 19 are slidably connected to the inner side of the temporary storage box 13. A sealing strip 20 is provided between the two push plates 19 and the temporary storage box 13. The temporary storage box 13 and the two push plates 19 are connected through... The sealing strip 20 is connected, and multiple support springs 18 are provided on one side of the push plate 19. A guide rod 15 is installed on the inner side of the support spring 18. Guide frames 14 are fixedly installed on both sides of the temporary storage box 13. The push plate 19 and the guide frame 14 are connected by multiple support springs 18. Under the elastic support of multiple support springs 18, the two push plates 19 can move towards each other and continuously pressurize the lubricating grease, so that the lubricating grease can be continuously delivered to the transmission part of the CNC machine tool through the conveying pipe 5, realizing a continuous and stable lubricating grease replenishment operation.

[0026] Two temporary storage boxes 13, sealing strips 20, and guide frames 14 are symmetrically installed relative to the center of the temporary storage box 13. Multiple guide rods 15 pass through the guide frame 14, the injection tube 3, and the support spring 18 and are fixedly connected to the push plate 19. A first electrically connected metal piece 16 is fixedly installed on one end corner of one of the guide frames 14, and a second electrically connected metal piece 17 is fixedly installed on one end of one of the guide rods 15. The first electrically connected metal piece 16 is fitted onto the outside of one of the guide rods 15 and makes insulated contact with one of the guide rods 15. When the first electrically connected metal piece 16 separates from the second electrically connected metal piece 17, the oil pump 10 is de-energized after a delay. When the second electrically connected metal piece 17 contacts the first electrically connected metal piece 16, the oil pump 10 is energized and started, thereby realizing the repeated extraction and delivery of lubricating grease, which facilitates the automatic replenishment of lubricating grease to the transmission parts of the CNC machine tool.

[0027] Working principle: When replenishing the lubricating grease in the transmission parts of the CNC machine tool, the grease storage box 1 is fixed on the outside of the CNC machine tool, so that the upper end of the temporary storage box 13 is connected to the transmission parts of the CNC machine tool through the material conveying pipe 5. The power is turned on, and the lubricating grease is injected into the inside of the storage bin 8 through the injection pipe 3. The oil pump 10 is started, so that the oil pump 10, under the support of the partition angle plate 7, draws the lubricating grease from the inside of the collecting cone seat 11 and injects it into the inside of the temporary storage box 13 for temporary storage.

[0028] At this time, the two push plates 19, which are symmetrically installed in the temporary storage box 13, slide in opposite directions under pressure when the lubricating grease is injected, and compress the support spring 18. The guide rod 15 drives the second energized metal piece 17 to separate from the first energized metal piece 16. After the first energized metal piece 16 separates from the second energized metal piece 17, the oil pump 10 is de-energized after a delay. Then, the two push plates 19 can move towards each other under the elastic support of multiple support springs 18 and continuously pressurize the lubricating grease. One-way valves are provided at the bottom of the injection pipe 3 and the output end of the oil pump 10, so that the lubricating grease can be continuously delivered to the transmission part of the CNC machine tool through the delivery pipe 5, realizing a continuous and stable lubricating grease replenishment operation.

[0029] When the push plate 19, supported by the support spring 18, drives the second electrically connected metal piece 17 to contact the first electrically connected metal piece 16 through the guide rod 15, the oil pump 10 is powered on and started, thereby realizing the repeated extraction and delivery of lubricating grease. This facilitates the automatic replenishment of lubricating grease to the transmission parts of the CNC machine tool, reduces the running time of the oil pump 10, and extends the service life of the oil pump 10. At the same time, the booster pump 4 injects air into the inside of the storage bin 8, so that the inside of the storage bin 8 can maintain a full state of lubricating grease inside the collecting cone seat 11 after being pressurized.
