Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of guide rail oil recovery, specifically a guide rail oil recovery structure for CNC machine tools. Background Technology
[0002] CNC machine tool guideway oil has excellent anti-friction properties, minimizing vibration or intermittent sliding at low speeds, ensuring sensitive, accurate, and stable operation of the hydraulic system, and extending the service life of the machine tool. Therefore, it is an essential component in the use of CNC machine tools. However, feedback from the domestic and international CNC machine tool markets indicates that few machine tool manufacturers consider the recycling and reuse of CNC machine tool guideway oil.
[0003] Currently, due to design flaws in the base structure of similar CNC machine tools both domestically and internationally, guide rail oil intermittently flows from the guide rail grooves into the base recess during machine operation and part processing. Because the rear end of the base recess is designed with an open structure, the guide rail oil flows down the recess from higher to lower levels, eventually flowing into the cutting fluid tank and mixing with the cutting fluid. To prevent guide rail oil contamination of the cutting fluid, designers typically incorporate an oil-fluid separator within the cutting fluid tank. Such a separator not only presents structural design challenges but also incurs high design costs. Furthermore, the separated guide rail oil cannot be recycled or reused. Utility Model Content
[0004] The purpose of this invention is to provide a CNC machine tool guide rail oil recovery structure to solve the problems mentioned in the background art.

[0006] As a further embodiment of this utility model: a groove is provided on one side of the oil drain pipe, and an installation plate is detachably installed in the groove by bolts. A filter block is provided on the side of the installation plate facing the inner cavity of the oil drain pipe, and the outer dimensions of the filter block correspond to the inner dimensions of the oil drain pipe.
[0007] As a further improvement of this utility model: a support plate is connected to one side of the bottom of the mounting plate, the support plate is U-shaped, and the filter block is placed on the support plate.

[0009] As a further improvement of this utility model: the bottom end of the slider is provided with a through groove, and the two ends of the through groove extend to the two ends of the slider.
[0010] This utility model has the following advantages: the structure uses an oil drain port and an oil drain pipe to drain the oil in the guide rail into the oil tank for collection, and then uses an oil pump, an oil pipe, and a diversion hole to transport the oil to the connection between the slider and the track rod, realizing the recovery and recycling of the oil, improving the connection effect between the track rod and the slider, and the oil drain pipe is equipped with a filter component, which can filter the oil during the recovery process, thus having stronger functionality and practicality.
