Description

Technical Field

[0001] This utility model relates to a cleaning and maintenance system for gear hobbing machines, specifically a cleaning and maintenance system based on micro-lubrication applied to gear hobbing machines. Background Technology

[0002] In the manufacturing sector, machine tools have widely adopted micro-lubrication technology from their initial design or after secondary modifications. The application of this technology varies depending on the process and the materials being processed. When machine tools using micro-lubrication technology process materials with high hardness, they generate a significant amount of powdery particles or other shaped removal materials. For example, after modifying a gear hobbing machine for micro-lubrication, a large amount of iron filings and powder easily accumulates inside the equipment. Traditional oil bath or liquid bath lubrication methods can flush these removal materials into the oil tank using liquid, but micro-lubrication technology uses compressed air as a power source, spraying out a very small amount of oil or liquid, thus failing to effectively remove these particulate powders.

[0003] In existing technologies, the handling of these powdery particles mostly relies on manual wiping or magnetic removal, which is extremely inefficient. Typically, cleaning one machine takes nearly two hours. Some higher-priced machines are equipped with self-cleaning functions. For example, patent CN217475492U discloses a chip removal device for CNC machine tools. During processing, water is sprayed onto the processing table and product through the nozzles of the cleaning mechanism to wash away debris and prevent it from remaining on the processing table and product.

[0004] However, older equipment typically lacks this function, and manual wiping or magnetic rod removal methods are inefficient and ineffective at removing solid waste such as iron filings and sludge accumulated inside the equipment. Therefore, for minor lubrication retrofits of older equipment, an advanced cleaning method is urgently needed to improve equipment maintenance efficiency. Utility Model Content

The oscillator mounting base includes an oscillator horizontal support 43, an oscillator fixing groove plate 45, and a triangular support 46.

[0048] like Figure 2 As shown, there are two triangular brackets 46, which are threadedly fixed to both sides of the oil drain port of the machine tool 11, presenting a symmetrical structure. There are two oscillator cross brackets 43, which are welded to the two triangular brackets 46 respectively; the oscillator fixing groove plate 45 is fixed to the two oscillator cross brackets 43 with screws; the power oscillator 31 is fixedly installed on the oscillator fixing groove plate 45.

[0049] like Figure 3 As shown, the oscillator controller 32 is mounted on the outer wall of the machine tool 11 and is electrically connected to the power oscillator 31 to control the operation of the power oscillator 31.

[0050] The oil guide groove 41 is installed below the two oscillator cross supports 43. One end of it is connected to the oil discharge port of the machine tool 11, and the other end corresponds to the input port of the chip conveyor 13.

[0051] The vibrating chip conveying groove 42 is installed inside the oil guide groove 41. One end of it is connected to the chip discharge port of the machine tool 11, and the other end corresponds to the input port of the chip conveyor 13.

[0052] There are two oscillator connection plates 44, symmetrically arranged on both sides of the power oscillator 31. The lower ends of the two oscillator connection plates 44 are threaded to the oscillation chip removal groove 42, and the upper ends are connected to the output end of the power oscillator 31.

[0053] The filter spraying module includes a liquid suction pipe 24, a liquid spraying pipe 25, and a cleaning machine 21; the cleaning machine 21 is equipped with a slag suction filter port 22 and a liquid outlet 23.

[0054] One end of the suction pipe 24 is connected to the output port of the oil tank 12, and the other end is connected to the sludge suction filter port 22. The sludge suction filter port 22 has a built-in filter screen and a suction oil pump. The suction pipe 24 is used to transport the iron filings, oil and sludge in the oil tank 12 to the cleaning machine 21. The filter screen of the sludge suction filter port 22 filters the iron filings, oil and sludge.

[0055] One end of the spray pipe 25 is connected to the outlet 23, and the other end is equipped with a high-pressure spray gun. The high-pressure spray gun extends into the oil inlet of the machine tool 11 to clean the iron powder and iron filings inside the machine tool 11. The outlet 23 has a built-in oil pump.

[0056] The cleaning machine 21 has a built-in oil tank with a capacity of ≥100L.

[0057] During use, this utility model can be divided into normal equipment processing and shutdown cleaning and maintenance processes. The cleaning machine 21 is placed on a mobile trailer and can be used to clean and maintain multiple machine tools 11.

[0058] Normal processing procedure of the equipment:

[0059] See Figure 1 , Figure 2 During normal processing, the power oscillator 31 is controlled by the oscillator controller 32 and operates in a high-frequency vibration state. The oscillator controller 32 is mainly used to adjust the oscillation frequency. The power oscillator 31 transmits the high-frequency oscillation to the oscillating chip removal groove 42 through the oscillator connecting plate 44. Under the control of the power oscillator 31, the oscillating chip removal groove 42 generates high-frequency vibration. After the waste chips generated inside the machine tool 11 enter the oscillating chip removal groove 42, they gradually flow into the chip conveyor 13 as the oscillating chip removal groove 42 vibrates at high frequency. The switch of the chip conveyor 13 is turned on, and the chip conveyor 13 discharges the waste chips through the second output port and inputs the filtered oil into the oil tank 12 through the first output port.

[0061] See Figure 1 , Figure 2 During the shutdown cleaning and maintenance process, machine tool 11 is in a stopped state, and cleaning machine 21 is controlled by a separate 220V power supply. The oil tank inside cleaning machine 21 is full of oil. Cleaning machine 21 is started, and the oil pump built into outlet 23 is opened, which draws oil from the tank. The spray pipe 25 is manually operated to use the pumped oil to clean the iron powder and accumulated iron filings inside machine tool 11. The washed-off iron powder and iron filings are discharged into chip conveyor 13 through vibrating chip conveying trough 42. Part of the liquid oil flows into chip conveyor 13 through oil guide trough 41, and the other part flows into chip conveyor 13 through vibrating chip conveying trough 42. After the chip conveyor 13 filters the liquid oil once, it is delivered to oil tank 12.

[0062] After the machine tool 11 is manually rinsed, the liquid pump in the suction filter port 22 is turned on, and the liquid oil, remaining iron filings and sludge in the oil tank 12 are all sucked in through the suction pipe 24. The filter screen built into the suction filter port 22 filters out the iron filings and sludge, and the liquid oil is stored in the oil tank built into the cleaning machine 21 for cleaning the next micro-lubrication equipment.
