[0033] The utility model provides a lubrication structure of lathe guide rail, through front oil passage 41 extends to the positive axial upper side of guide rail body 2 from slide 3, and rear oil passage 42 extends to the negative axial upper side of guide rail body 2 from slide 3, forms the path of bidirectional delivery lubricating oil, increases the coverage area and distribution uniformity of lubricating oil.Moreover, when slide 3 is sliding along guide rail body 2, slide 3 can flow out lubricating oil at every position, keeps the lubrication state with guide rail body 2, greatly reduces the friction coefficient between guide rail body 2 and slide 3, reduces wear and energy loss, further improves the machining accuracy and service life of lathe, and ensures the stability and reliability of lubrication effect in long-term operation process.

[0034] The lubricating structure of the lathe guide rail further comprises a positioning assembly 5 arranged on the top of the slide 3, which is used to position the oil pump. Specifically, the positioning assembly 5 comprises a clamping site 51 and a positioning cover 52. The clamping site 51 is arranged on the top surface of the slide 3, and the shape of the clamping site 51 is accurately matched with the bottom profile of the oil pump.

[0035] The lubricating structure of the lathe guide rail further comprises a positioning assembly 5 arranged on the top of the slide 3, which is used to position the oil pump. Specifically, the positioning assembly 5 comprises a clamping site 51 and a positioning cover 52. The clamping site 51 is arranged on the top surface of the slide 3, and the shape of the clamping site 51 is accurately matched with the bottom profile of the oil pump. By finely polishing and processing the inside of the clamping site 51, the surface flatness and roughness thereof can meet the installation requirements, so that the oil pump can be stably and tightly supported, and displacement of the oil pump during operation due to vibration can be effectively prevented. The positioning cover 52 is detachably positioned on the clamping site 51, and a plurality of threaded holes can be arranged on the positioning cover 52 and matched with corresponding threaded columns on the clamping site 51, so as to firmly install the positioning cover 52. The clamping force of the oil pump can be adjusted by the tightening degree, so as to adapt to the installation requirements of oil pumps of different models and sizes, and ensure that the positioning of the oil pump on the slide 3 is accurate and reliable, and sufficient oil pressure is continuously and stably provided for the lubrication of the guide rail, thereby ensuring efficient operation of the entire lubricating system.

[0036] During operation of the lathe, if waste accumulates, especially fine debris, it is easy to mix into the lubricating oil path with the movement of the slide 3, scratch the inner wall of the oil path, damage the integrity of the oil film, and cause lubrication failure. Through the inclined discharge port 61, waste can be timely and completely removed to prevent it from invading the lubrication path, ensuring that the lubricating oil flows smoothly and cleanly in the oil path, and continuously providing stable lubrication for the guide rail body 2 and the slide 3.

[0037] In use, the discharge assembly 6 can be equipped with a small discharge fan, which is connected with the discharge port 61 and can further enhance the discharge capacity of the waste through the generated negative pressure airflow, especially for some small debris and dust, which can be more thoroughly sucked out and discharged from the base 1. The speed of the fan can be adjusted according to the machining conditions of the lathe. When a large amount of waste is generated during high-speed cutting, the speed of the fan is increased to ensure that the waste is discharged in time. Moreover, the airflow generated by the fan can assist in pushing the lubricating oil seeping out of the oil way of the slide 3, so as to make the lubricating oil spread more evenly on the surface of the guide rail body 2, avoid the problem of excessive or insufficient lubrication caused by the accumulation or uneven distribution of lubricating oil, and make the slide 3 slide more smoothly on the guide rail body 2, effectively reduce the friction coefficient, prolong the service life of the equipment, and improve the machining accuracy of the lathe.

[0038] The lubricating structure of the lathe guide rail further comprises a disassembly and assembly assembly 7 arranged at the side end of the base 1, and the guide rail body 2 is positioned in the disassembly and assembly assembly 7. The disassembly and assembly assembly 7 is used for disassembling and assembling the guide rail body 2. Specifically, the disassembly and assembly assembly 7 comprises an opening 71 and a mounting plate 72. The opening 71 is arranged at the side end of the base 1, and the mounting plate 72 is detachably positioned in the opening 71. The mounting plate 72 can be made of high-strength aluminum alloy material, which can effectively reduce the overall weight while ensuring sufficient rigidity, and is convenient for operators to disassemble and assemble. The guide rail body 2 is positioned in the mounting plate 72.

[0039] By arranging the mounting plate 72 to be detachably positioned in the opening 71, the replacement and maintenance of the guide rail body 2 becomes efficient and convenient. When the guide rail body 2 is disassembled and maintained, since the mounting plate 72 can be removed conveniently, the operators can directly contact each lubrication point of the guide rail body 2, which facilitates the thorough cleaning of the long-term accumulated dirt and impurities, prevents the oil way from being blocked, ensures that the subsequent lubricating oil can flow smoothly inside the guide rail body 2, and maintains good lubricating effect.

[0040] Preferably, a plurality of precisely machined positioning pin holes and threaded holes can be arranged on the mounting plate 72. These hole positions are matched with the corresponding hole positions on the guide rail body 2. Through the precise positioning of the positioning pin and the fastening connection of the bolt, the installation position of the guide rail body 2 on the mounting plate 72 can be ensured to be accurate, which guarantees the cooperation accuracy between the guide rail body 2 and the slide 3, and further maintains the machining accuracy of the lathe.

[0041] Preferably, the surface of the guide rail body 2 is provided with a wear-resistant protective layer 8 for protecting the guide rail body 2, which can adopt a phosphating coating. In small mechanical processing plants, the phosphating coating plays a protective role for the guide rail body 2, so that the guide rail body 2 has a complete shape and ensures the smooth operation of the slide block 3. After the lubricating oil uniformly seeps out of the oil channel of the slide block 3, it can smoothly spread on the surface of the phosphating coating, reducing the rupture of the oil film and the local lack of oil caused by the unevenness or wear of the guide rail surface, and continuously providing stable lubrication for the relative movement of the slide block 3 and the guide rail.

[0042] The lubricating structure of the lathe guide rail further comprises a tool positioning plate 9 which is detachably positioned on the top of the slide block 3 and can be screw-connected with the slide block 3. The tool positioning plate 9 is used for positioning the tool. When different types and specifications of tools need to be switched to adapt to diversified processing tasks, the operator only needs to loosen the fastening device on the tool positioning plate 9 to easily remove the old tool and install a new tool. The whole process is simple and efficient, greatly shortening the tool changing time and improving the operation efficiency of the lathe. Moreover, since the tool positioning plate 9 is detachable, it can be taken out alone during daily maintenance to comprehensively clean and lubricate the top of the slide block 3, the tool positioning plate 9 itself and the contact part of the tool and the positioning plate, effectively preventing the accumulation of chips and rust from affecting the positioning accuracy of the tool, further ensuring the long-term stable operation of the lathe, reducing the processing scrap rate caused by poor tool positioning and enhancing the stability of product quality.

[0043] Further, the tool positioning plate 9 is attached to the top of the slide block 3 to enhance the rigidity of the whole slide block 3 and reduce the deformation of the slide block 3 caused by cutting force, vibration and other factors during processing. The stable structure of the slide block 3 is conducive to maintaining the stable pressure and oil outlet state of the oil channel, so that the lubricating oil can uniformly and continuously flow to the guide rail body 2, avoiding the local pressure or obstruction of the oil channel caused by the deformation of the slide block 3, ensuring that the tool is accurately positioned while the friction between the slide block 3 and the guide rail body 2 is always in a good lubricated state, thereby improving the processing accuracy and stability of the lathe and prolonging the service life of the equipment.

[0044] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application is disclosed as above, it is not intended to limit the present application.
