Description

Technical Field

[0001] This invention relates to the field of machine tool lubrication devices, specifically a lubrication device for the maintenance of CNC machine tools. Background Technology

[0002] The lubrication device for CNC machine tool maintenance is a key component of the CNC machine tool lubrication system. It is mainly responsible for providing clean and sufficient lubricating oil to the various moving parts of the machine tool to reduce friction and wear, and ensure the machining accuracy and operational stability of the machine tool. The device usually consists of an oil tank, oil pump, filter assembly, control unit and pipelines. The filter assembly is used to intercept impurities in the oil, ensure the quality of the lubricating oil and extend the service life of the machine tool.

[0003] Under current technological conditions, refueling an oil tank generally requires workers to first unscrew the oil cap and open the filler neck, then tilt the heavy oil drum to slowly pour the oil through the narrow filler neck. During this process, the oil must be filtered by a filter cartridge before entering the oil tank. After refueling, to ensure that the lubricating oil inside the oil tank is effectively isolated from the external environment, the oil cap must be accurately reset and tightened again. The entire refueling process is cumbersome and inefficient. In addition, the filter cartridge is prone to clogging due to the accumulation of impurities during long-term use. The common cleaning method is to manually remove the filter cartridge from the oil tank and then manually clean it. This operation is not only inconvenient but also easily causes workers' hands to become oily, resulting in discomfort. Therefore, in view of the above problems, a lubrication device for the maintenance of CNC machine tools is proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a lubrication device for the maintenance of CNC machine tools, so as to solve the problem that the lubrication oil addition operation of existing lubrication devices for the maintenance of CNC machine tools is cumbersome and inefficient.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A lubrication device for CNC machine tool maintenance includes an oil tank, which comprises a tank body. A cover is installed on the upper side of the tank body, and an oil filling port is opened on the upper side of the cover. An oil delivery assembly is installed on the cover, and an oil filling module is installed on the upper side of the cover. The oil filling module includes a cover fixed inside the oil filling port. A rotating opening is opened on the upper side of the cover, and several guide holes are opened on the upper side of the cover surrounding the outside of the rotating opening. A filter cartridge is rotatably connected to the inner side of the rotating opening, and a sealing part is installed on the outer side of the filter cartridge. The sealing part includes several guide rods slidably connected to the guide holes. A sealing seat for sealing the lower opening of the filter cartridge is fixedly connected to the lower end of the guide rods. An oil guide bucket is fixedly connected to the upper end of the guide rods, and a connecting fitting tube is fixedly connected to the lower side of the oil guide bucket. A spring is sleeved on the outer side of each guide rod.

[0006] Preferably, a controller is installed on the upper side of the cover, a gap is provided between the oil guide bucket and the upper end face of the cover, and all springs are disposed between the oil guide bucket and the cover.

[0007] Preferably, the upper end face of the sealing seat is in contact with the lower end face of the filter cartridge, and the sealing seat is composed of a base and a sealing ring fixed on the outside of the base. The outer curved surface of the sealing ring of the sealing seat is in close contact with the inner wall of the lower opening of the cover.

[0008] Preferably, the lower end of the fitting tube is inserted into the filter cartridge, the diameter of the fitting tube is the same as the inner diameter of the filter cartridge, and the outer curved surface of the fitting tube fits against the inner curved surface of the filter cartridge.

[0009] Preferably, the upper left side of the cover has a sliding opening, the left side of the cover has a pair of insertion ports, the left side of the refueling module has a dredging part, the dredging part includes a side shell fixed to the left side of the cover, the right side of the side shell has a pair of vent plates passing through the insertion ports, the right side of the side shell has a rail opening aligned with the sliding opening, the inner side of the rail opening has a locking component, the locking component includes a transmission block slidably connected to the rail opening and the sliding opening, the right notch of the transmission block has a locking block fixedly connected, the left side of the left guide rod has a slot, the lower side of the transmission block has a protrusion fixedly connected, the right end face of the protrusion is fixedly connected to the right inner wall of the side shell, the upper side of the side shell has an interface, the inner side of the interface has an air supply pipe fixedly connected, the left end of the air supply pipe has a fixedly connected air pump in a communicating manner, and the air pump is fixed on the upper side of the cover, and the inner side of the filter cartridge has a discharge component.

[0010] Preferably, the discharge component includes a rubber pad that fits against the lower inner wall of the filter cartridge, a connecting rod is fixedly connected to the upper side of the rubber pad, and a pinch block is fixedly connected to the upper end of the connecting rod.

[0011] Preferably, rubber baffles are fixedly connected to the front and rear inner walls of the ventilation insert, with the opposing ends of the rubber baffles on the front and rear sides abutting each other, the locking block and the locking groove being horizontally aligned, and the locking element being located on the lower side of the interface.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the structure including the cover, spring 1, sealing part, and filter cylinder allows the filter cylinder to be installed inside the cover, ensuring that all lubricating oil passing through the cover is filtered by the filter cylinder. The sealing part, in conjunction with spring 1, normally seals the lower opening of the cover, which in turn seals the oil tank. When adding oil, spring 1 contracts, and the sealing part no longer seals the lower opening of the cover. After adding oil, spring 1 returns to its original position and the sealing part seals the lower opening of the cover again, thus completing the sealing of the oil tank. This invention enables operators to directly add lubricating oil to the sealed oil tank in the lubrication device for CNC machine tool maintenance, and automatically isolates the lubricating oil from the external environment after adding oil. This solves the problem of cumbersome lubrication adding operations and low efficiency in existing CNC machine tool maintenance lubrication devices. 2. In this invention, the structure of the unblocking part, the discharge part, the filter cylinder, and the discharge part allows the airflow from the unblocking part to partially backflush the filter cylinder and position the sealing part. The discharge part can rotate the filter cylinder, allowing it to be fully unblocked by the unblocking part, so that the impurities fall onto the rubber pad of the discharge part. Furthermore, the impurities inside the filter cylinder can be cleaned out by removing the discharge part, thus solving the problems of inconvenient manual cleaning of the filter cylinder and psychological discomfort caused by oil stains.

[0015] Please see Figure 1-11 The present invention provides a technical solution: A lubrication device for CNC machine tool maintenance includes an oil tank 1, which includes a housing 11. A cover 12 is mounted on the upper side of the housing 11, and an oil filling port 13 is provided on the upper side of the cover 12. An oil delivery assembly 2 is mounted on the cover 12, and an oil filling module 4 is mounted on the upper side of the cover 12. The oil filling module 4 includes a cover 41 fixed inside the oil filling port 13, a pivot 42 is provided on the upper side of the cover 41, and several guide holes 4 are provided on the upper side of the cover 41 surrounding the outer side of the pivot 42. 3. A filter cartridge 46 is rotatably connected to the inner side of the rotating port 42. A sealing part 47 is installed on the outer side of the filter cartridge 46. The sealing part 47 includes several guide rods 471 that are slidably connected to the guide holes 43. A sealing seat 472 for sealing the lower opening of the filter cartridge 46 is fixedly connected to the lower end of the guide rods 471. An oil guide hopper 473 is fixedly connected to the upper end of the guide rods 471. A mating tube 474 that is connected in a continuous manner is fixedly connected to the lower side of the oil guide hopper 473. A spring is sleeved on the outer side of each guide rod 471. 48; A controller 3 is installed on the upper side of the cover 12. A gap is provided between the oil guide hopper 473 and the upper end face of the cover 41. Springs 48 are all set between the oil guide hopper 473 and the cover 41. This arrangement allows the oil guide hopper 473 to move downward, and the springs 48 can reset the downward-moving oil guide hopper 473 upward. The upper end face of the sealing seat 472 is in contact with the lower end face of the filter cartridge 46. The sealing seat 472 consists of a base and a sealing ring fixed on the outside of the base. The outer curved surface of the sealing ring of the sealing seat 472 fits tightly against the inner wall of the lower opening of the cover 41. This arrangement allows the sealing seat 472 to seal the lower opening of the cover 41. The lower end of the fitting tube 474 is inserted into the filter cartridge 46. The diameter of the fitting tube 474 is the same as the inner diameter of the filter cartridge 46. The outer curved surface of the fitting tube 474 fits against the inner curved surface of the filter cartridge 46. This arrangement allows the oil guide bucket 473 to move downward without affecting the connection between the oil guide bucket 473 and the filter cartridge 46.

[0016] like Figures 4-11 As shown, a sliding opening 44 is provided on the upper left side of the cover 41, and a pair of insertion ports 45 are provided on the left side of the cover 41. A dredging part 5 is installed on the left side of the refueling module 4. The dredging part 5 includes a side shell 51 fixed to the left side of the cover 41. A pair of vent plates 52 passing through the insertion ports 45 are fixedly connected to the right side of the side shell 51. A rail opening 54 is provided on the right side of the side shell 51, which is aligned with the sliding opening 44. A locking member 55 is installed inside the rail opening 54. The locking member 55 includes a transmission block 551 that is slidably connected to the rail opening 54 and the sliding opening 44. The right notch of the transmission block 551 is fixed inside the rail opening 551. A locking block 552 is connected, and a slot 475 is provided on the left side of the left guide rod 471. A protrusion 553 is fixedly connected to the lower side of the transmission block 551. A spring 56 is fixedly connected between the right end face of the protrusion 553 and the right inner wall of the side shell 51. An interface 57 is provided on the upper side of the side shell 51. An air supply pipe 58 is fixedly connected to the inner side of the interface 57. An air pump 59 is fixedly connected to the left end of the air supply pipe 58 and is fixed on the upper side of the cover 12. A discharge part 6 is installed inside the filter cartridge 46. This arrangement allows the airflow from the unblocking part 5 to flow through to one side. The filter cartridge 46 can be partially backflushed, and the sealing part 47 can be positioned. The discharge part 6 includes a rubber pad 62 that fits against the lower inner wall of the filter cartridge 46. A connecting rod 61 is fixedly connected to the upper side of the rubber pad 62, and a pinch block 63 is fixedly connected to the upper end of the connecting rod 61. With this arrangement, the discharge part 6 can rotate to drive the filter cartridge 46 to rotate, so that the filter cartridge 46 can be fully backflushed and cleared by the clearing part 5, so that the impurities that are cleared fall onto the rubber pad 62 of the discharge part 6. On the other hand, the filter cartridge 46 can be cleaned by removing the discharge part 6. Impurities are removed; rubber baffles 53 are fixedly connected to the front and rear inner walls of the vent plate 52, and the opposing ends of the front and rear rubber baffles 53 are in contact with each other. This setting can prevent lubricating oil from entering the side shell 51 through the vent plate 52 when refueling. The locking block 552 and the slot 475 are horizontally aligned. The locking element 55 is located on the lower side of the interface 57. This setting allows the gas sprayed downward from the interface 57 to push the locking element 55 to the right, so that the locking block 552 of the locking element 55 is inserted into the inner side of the slot 475 to position the sealing part 47.

[0017] Workflow: Note 1: All electrical appliances used in this application are externally powered and controlled by controller 3; Note 2: The oil delivery assembly 2 is existing technology equipment, consisting of an oil pump, pressure gauge, oil drain, and delivery pipeline, used to deliver clean and sufficient lubricating oil to various moving parts of the machine tool; The lubrication operation of the CNC machine tool maintenance lubrication device is as follows: When the lubricating oil in the housing 11 is insufficient, the operator tilts the oil drum and presses it onto the oil guide hopper 473 of the sealing part 47. The pressure on the oil guide hopper 473 pushes the sealing seat 472 downward through the guide rod 471, compressing the spring 48. The downward movement of the sealing seat 472 opens the lower opening of the cover 41; simultaneously, the lubricating oil in the oil drum is tilted and poured into the oil guide hopper 473, through which... The lubricating oil is guided into the filter cartridge 46 through the connecting tube 474. The lubricating oil then moves outward through the filter cartridge 46 and finally exits from the lower opening of the cover 41, entering the tank 11. During this process, the filter cartridge 46 filters impurities from the lubricating oil. When the oil level in the tank 11 reaches a suitable height, the oil drum is removed from the upper side of the oil guide hopper 473, and the oil guide hopper 473 is no longer pressed down. At this time, each spring 48 will elastically unfold, pushing the oil guide hopper 473, guide rod 471, and sealing seat 472 of the sealing part 47 upward to reset, causing the sealing seat 472 to reseal the lower opening of the cover 41, thus effectively isolating the lubricating oil in the oil tank 1 from the outside. The above steps complete the refueling operation. The lubrication device for CNC machine tool maintenance allows operators to directly add lubricating oil to the sealed oil tank 1, and automatically isolates the lubricating oil from the external environment after adding oil. This solves the problem of cumbersome lubrication adding operations and low efficiency of existing CNC machine tool maintenance lubrication devices. Cleaning operation: When it is necessary to clean the impurities clogging the inner wall of the filter cartridge 46, the air pump 59 is started by the controller 3. The air pump 59 delivers externally drawn airflow through the air supply pipe 58 and interface 57 from top to bottom into the side shell 51. During this process, the airflow pushes the locking member 55 to the right, causing the locking block 552 of the locking member 55 to insert into the slot 475 of the sealing part 47, thus sealing the part. Positioning is performed at 47 to keep the sealing seat 472 in place; at the same time, the gas in the side shell 51 will push the rubber baffle 53 to deform elastically, allowing the gas to be ejected through the vent plate 52, and partially backflushing the filter cartridge 46 from left to right. At this time, the operator can rotate the squeezing block 63, connecting rod 61 and rubber pad 62 of the discharge part 6 to drive the filter cartridge 46 to rotate, so that the backflushing airflow can fully backflush and unclog the filter cartridge 46. The unclogged impurities will fall onto the rubber pad 62. At this time, the operator only needs to pull up the discharge part 6 to remove the discharge part 6 and impurities from the filter cartridge 46, completing the unclogging and cleaning of the filter cartridge 46. This solves the problems of inconvenience in manually cleaning the filter cartridge 46 and psychological discomfort caused by oil stains.
