It is suitable for machining flat and inclined surfaces on large workpieces in batch and mass production. CNC gantry milling machines can also process curved surfaces and some special-shaped parts.

[0003] However, due to the long service life of machine tools or long-term high-load use, the internal lubrication system of the gearbox has been working for a long time and is easily blocked due to the accumulation of internal debris or the entry of external dust, resulting in unstable oil pressure and insufficient lubricating oil supply, which makes the internal gears not lubricated properly and causes gear wear. The metal debris generated by gear wear will further increase the wear inside the gearbox, and then the existing gearbox lubrication system cannot function normally. Not only that, since the gantry milling machine is suitable for continuous processing of large workpieces or large batches of workpieces, the gantry milling machine has long-term and high-intensity processing, and the gearbox easily accumulates heat during long-term processing, causing the gantry milling machine to have inconsistent accuracy during continuous processing, which urgently needs to be improved.

[0016] First, the oil delivery component can use the oil delivery pump to pump the lubricating oil in the oil tank into the gear box, and pump the lubricating oil in the gear box into the oil tank, thereby forming a circulating oil circuit between the gear box and the oil tank, which is convenient for replenishing the lubricating oil in the oil tank into the gear box; at the same time, by replenishing or replacing the lubricating oil in the oil tank, the lubricating oil in the gear box can always be kept at a reasonable liquid level, and the impurity content of the lubricating oil in the gear box can be prevented from being too high, solving the technical problem that the lubricating oil circuit in the existing gear box is easily blocked by excessive impurities; secondly, the cooling component in the present invention can take away the heat of the gear box through the mutual cooperation of the cooling fan and the cooling plate, reduce the temperature difference of the internal temperature of the gear box during the processing, thereby solving the technical problem of poor consistency of the processing accuracy of the gantry milling machine caused by the increase in the internal temperature of the gear box.

[0030] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] Please also refer to Figures 1 to 2The gearbox lubrication system provided by the present invention is now described. The gearbox lubrication system includes an oil delivery component 1 and a cooling component 2, wherein the oil delivery component 1 includes an oil delivery pump 11, an oil inlet pipeline 12, an oil outlet pipeline 13 and an oil tank 14. The oil tank 14 is arranged on the side wall of the gearbox 4. One end of the oil inlet pipeline 12 is connected to the oil inlet of the gearbox 4, and the other end is connected to the oil outlet of the oil delivery pump 11. One end of the oil outlet pipeline 13 is connected to the oil outlet of the gearbox 4, and the other end is connected to the oil inlet of the oil tank 14. One end of the oil delivery pump 11 is connected to the oil outlet of the oil tank 14, and the other end is connected to the oil inlet pipeline 12. 2 includes a cooling plate 21 and a cooling fan 22. The cooling plate 21 is closely attached to the side wall of the gear box 4. The oil inlet pipeline 12 and the oil outlet pipeline 13 are both connected to the gear box 4 through the cooling plate 21. An oil outlet flow channel 212 and an oil inlet flow channel 211 are formed in the cooling plate 21. The oil inlet flow channel 211 can connect the oil inlet pipeline 12 and the gear box 4, and the oil outlet flow channel 212 can connect the oil outlet pipeline 13 and the gear box 4. In addition, the cooling fan 22 is provided on the other side of the cooling plate 21 away from the gear box 4, and the rotation axis of the cooling fan 22 extends along the thickness direction of the cooling plate 21. The heat of the gear box 4 is taken away by the cooperation of the cooling fan 22 and the cooling plate 21, and the temperature difference of the internal temperature of the gear box 4 during the processing is reduced, thereby solving the technical problem of poor consistency of the processing accuracy of the gantry milling machine caused by the increase in the internal temperature of the gear box 4; in addition, in this embodiment, the oil delivery component 1 can use the oil delivery pump 11 to pump the lubricating oil in the oil tank 14 into the gear box 4, and pump the lubricating oil in the gear box 4 into the oil tank 14, thereby forming a circulating oil path between the gear box 4 and the oil tank 14, which is convenient for replenishing the lubricating oil in the oil tank 14 into the gear box 4; at the same time, by replenishing or replacing the lubricating oil in the oil tank 14, the lubricating oil in the gear box 4 can always be kept at a reasonable liquid level, and the impurity content of the lubricating oil in the gear box 4 can be prevented from being too high, thereby solving the technical problem that the lubricating oil path in the existing gear box 4 is easily blocked due to excessive impurities.

[0032] Based on the above embodiment, in order to prevent the rotation of the cooling fan 22 from interfering with the work of the workshop operator, a feasible implementation method is proposed. Specifically, the cooling assembly 2 also includes a protective cover 23 and a drive motor 24. The protective cover 23 is connected to the cooling plate 21, and a storage space for accommodating the cooling plate 21 is formed between the protective cover 23 and the cooling plate 21. The drive motor 24 is arranged in the protective cover 23, and the drive motor 24 is used to drive the cooling fan 22 to rotate. In this embodiment, the protective cover 23 can cover the cooling fan 22 between the cooling plate 21 and the protective cover 23, preventing the cooling fan 22 from posing a safety hazard to the workshop operator during rotation, and is conducive to the continuous operation of the cooling fan 22. Not only that, in the process of driving the cooling fan 22 to rotate, the cooling fan 22 can also dissipate heat from the drive motor 24 to prevent the drive motor 24 from overheating.

[0033] To enhance the cooling effect of the cooling assembly 2 on the gearbox 4, a feasible implementation is proposed. Specifically, a heat sink is provided on the side of the cooling plate 21 facing away from the gearbox 4. The heat sink's surface is perpendicular to the surface of the cooling plate 21. This increases the heat dissipation area of the cooling plate 21, thereby enhancing the heat exchange capacity of the cooling plate 21 and improving the heat dissipation effect of the cooling fan 22 on the cooling plate 21.

[0034] Furthermore, a feasible implementation method is proposed. Specifically, the oil outlet channel 212 and the oil inlet channel 211 are both arranged in a "J" shape in the cooling plate 21 to enhance the flow area of the lubricating oil in the cooling plate 21 and improve the heat exchange capacity of the cooling plate 21. Preferably, the oil outlet channel 212 and the oil inlet channel 211 are symmetrically distributed in the cooling plate 21 to facilitate the assembly and processing of the cooling plate 21.

[0035] In addition to the above-mentioned feasible embodiments, a feasible embodiment is proposed to solve the technical problem of colloids and metal debris clogging the lubricating oil circuit. Specifically, in this embodiment, a filter assembly 3 is provided between the oil pump 11 and the gearbox 4. The filter assembly 3 includes a filter line 31 and a filter element 32. The filter element 32 is filled in the filter line 31. The filter element 32 is used to filter the lubricating oil flowing through the filter line 31, making the lubricating oil cleaner. This solves the existing technical problem of lubricating oil clogging the oil circuit due to excessive impurities, reduces the amount of oil added to the oil tank 14, and allows the current amount of oil in the oil tank 14 to provide a longer service life. Optionally, the filter element 32 is configured as a return oil filter element 32, which only requires a relatively low pressure to allow the oil to pass through the filter element 32, thereby reducing the flow resistance of the lubricating oil in the entire oil circuit.

[0036] In order to reduce the number of times the filter element 32 needs to be replaced and reduce the iron filings content in the lubricating oil, the filter assembly 3 also includes a magnetic block arranged in the filter pipeline 31. The magnetic block is used to adsorb ferromagnetic particles in the lubricating oil. When the magnetic block adsorbs a large amount of iron filings, the magnetic block is removed from the filter pipeline 31, cleaned, and then put back into the filter pipeline 31 to continue adsorbing the iron filings in the filter pipeline 31.

[0037] Based on the above embodiment, a more preferred embodiment is proposed. Specifically, the cooling assembly 2 further includes a mounting bolt 33, to which a magnetic block is integrally connected, and the mounting bolt 33 can be threadedly connected to the side wall of the filter pipe 31. The magnetic block can be removed or installed by removing and installing the mounting bolt 33 from the filter pipe 31, making the removal and installation of the magnetic block in the filter pipe 31 more portable. Optionally, the mounting bolt 33 with the magnetic block is located upstream of the filter element 32 to preemptively absorb iron filings in the filter pipe 31. This is because the removal and installation of the mounting bolt 33 makes the filter element 32 more portable and can reduce the frequency of filter element 32 replacement.

[0038] In summary, compared with the existing technology, the present invention can form a circulating flow of the lubricating oil circuit through the mutual cooperation between the oil pump 11, the oil tank 14 and each pipeline, and reduce the temperature of the lubricating oil through the joint action of the cooling plate 21 and the fan, which can not only ensure the quality of the lubricating oil in the gear box 4, but also reduce the temperature difference of the internal temperature of the gear box 4 during the processing process through the cooled lubricating oil, thereby solving the technical problem of poor consistency of the processing accuracy of the gantry milling machine caused by the increase in the internal temperature of the gear box 4. Not only that, the protective cover 23 in the present invention can prevent the cooling fan 22 from causing damage to the operator of the lathe, and also provide a suitable installation position for the drive motor 24; in addition, the filter assembly 3 in the present invention can absorb iron chips through the filter element 32 and the magnetic block, improve the quality of the lubricating oil, and reduce the amount of lubricating oil added to the oil tank 14.

[0039] Based on the same inventive concept, the present invention also provides a gantry milling machine, which includes the gear box lubrication system mentioned above.

[0040] Compared with the existing technology, the gantry milling machine in the present invention can lubricate the internal structure of the gear box 4 through the above-mentioned gear box lubrication system, and can keep the internal temperature of the gantry milling machine gear box 4 relatively consistent through the cooling component 2, thereby solving the technical problem that the existing gantry milling machine cannot maintain consistency in precision during long-term and high-intensity milling operations.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
