Description

Technical Field

[0001] This utility model relates to the field of thin oil treatment technology, specifically a thin oil lubrication device for CNC machine tools. Background Technology

[0002] CNC machine tools require regular lubrication to prevent wear and rust. A centralized thin oil lubrication system offers significant advantages because the pressure-fed oil supply provides sufficient volume, ensuring timely lubrication of numerous, widely distributed lubrication points. Simultaneously, it removes the friction heat generated by the friction pairs; metal abrasive particles and other mechanical impurities on the friction surfaces are carried away and cleaned by the oil flow and circulation. This achieves good lubrication, reduced friction, lower wear, reduced consumption of vulnerable parts, reduced power consumption, and extended equipment lifespan. However, traditional thin oil lubrication systems often fail to effectively cool the oil during operation.

[0003] Chinese patent discloses a thin oil lubrication device for CNC machine tools (authorization announcement number CN 218837025 U). This patented technology can fully stir and evenly cool the thin oil, preventing filter plate clogging and improving filtration efficiency. However, it lacks a debris collection device, leading to easy accumulation of debris, and requires additional oil heating in winter. Therefore, this utility model provides a thin oil lubrication device for CNC machine tools to solve the problems mentioned in the background art. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 In this embodiment of the utility model, the thin oil lubrication device for CNC machine tools includes a collection tank 1, a partition 2 fixed inside the collection tank 1, a collection frame 3 on the right side of the partition 2, a cleaning mesh plate 14 on the left side of the partition 2, a heat dissipation box 4 on the left side of the collection tank 1, a storage box 5 and a coil 8 on the lower side of the heat dissipation box 4 respectively through a three-way pipe 16, a three-way valve at the three-way pipe 16, a telescopic pipe 6 connecting the lower side of the storage box 5 to the coil 8, a corrugated pipe connecting the upper end of the coil 8 to the liquid outlet, a temperature sensor at the liquid outlet, an electric telescopic rod 7 connecting the coil 8, heat dissipation fins on the outer side of the heat dissipation box 4, a heat dissipation plate 10 on the lower side of the heat dissipation box 4, and a heat dissipation fan 9 connected to the heat dissipation plate 10.

[0026] The stirring blade 12 is rotatably connected inside the heat dissipation box 4. The upper end of the stirring blade 12 is connected to the motor 11 via a worm gear. The motor 11 is connected to the transmission rod 18 via a worm gear. The upper end of the transmission rod 18 is connected to the collection plate 15 via a bevel gear set 17. The cleaning screen 14 is slidably connected inside the collection plate 15. The lower end of the cleaning screen 14 is provided with a brush. The brush presses against the filter screen on the lower side to clean the impurities on the filter screen. Both the front and rear ends of the cleaning screen 14 are rotatably connected to rollers. The rollers are rotatably connected in the guide groove 13. The guide groove 13 is located on the inner wall of the collection tank 1. The lower side of the guide groove 13 is parallel to the left side of the partition 2 and the bottom of the collection tank 1. The guide groove 13 is a closed loop with rounded corners. The heat dissipation plate 10 is circular, and the upper opening of the heat dissipation plate 10 faces the outside of the heat dissipation box 4. The telescopic tube 6 is connected by a sleeve and a movable tube. The sleeve is connected to a water pump. The lower end of the movable tube is provided with a sealing ring to improve the sealing between it and the sleeve.

[0027] The working principle of this utility model is as follows: When in use, after the thin oil is lubricated by the CNC machine tool, the thin oil is collected on the left side of the collection tank 1, falls into the heat dissipation box 4 after passing through the filter screen, and then enters the storage box 5 through the three-way pipe 16. Finally, the thin oil is pumped through the telescopic pipe 6 and the coil 8 to the outlet, where a temperature sensor is installed for recycling.

[0028] After a period of use, impurities accumulate on the left side of the collection tank 1. The motor 11 drives the transmission rod 18 to rotate, and the transmission rod 18 drives the collection plate 15 to rotate through the bevel gear set 17, which in turn drives the cleaning screen 14 to move. The cleaning screen 14 pushes the impurities to the partition 2 through the restriction of the guide groove 13, and pushes the impurities accumulated on the partition 2 to the upper right and into the collection frame 3 for collection.

[0029] After a period of use, the temperature of the thin oil rises and is dissipated through the fins on the outside of the heat sink 4. Finally, it is discharged through the pump. The temperature at the outlet is monitored by a temperature sensor. When the temperature at the outlet is low, the three-way pipe 16 connects to the coil 8, the electric telescopic rod 7 extends, and the coil 8 is positioned on the outside of the heat sink 4 to be heated by the temperature of the heat sink 4. When the temperature at the outlet is high, the three-way pipe 16 connects to the storage tank 5, the electric telescopic rod 7 shortens, and the coil 8 provides auxiliary heat dissipation. When the temperature continues to rise, the cooling fan 9 blows cold air, the heat sink 10 cools the fins with the cold air, and the stirring blade 12 stirs to improve uniformity.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
