Description

Technical Field

[0001] The utility model relates to the technical field of chip liquid filtration, in particular to a chip liquid recycling filtration device for chain pin shaft processing. Background Art

[0002] Chain pins are crucial components in chain transmissions and are widely used in transmission systems across a wide range of machinery, including automobiles, motorcycles, and bicycles. Chain pin machining typically requires high-precision CNC machine tools and specialized equipment to ensure dimensional accuracy and surface quality. Furthermore, to improve machining efficiency and extend tool life, cutting fluids are often used for cooling and lubrication. These fluids play a crucial role in the machining process, providing cooling, lubrication, chip removal, and rust prevention. The cutting fluid used in chain pin machining is filtered to ensure reusability. By effectively filtering out metal debris and impurities from the cutting fluid, the fluid's cleanliness is ensured, extending its service life while reducing production costs and environmental pollution.

[0003] Publication number CN218856339U discloses a chip liquid filtering device for a machining center, comprising a base plate, two groups of pillars are fixedly mounted on the top of the base plate, a connecting seat is fixedly mounted on the top of one group of pillars, and a liquid inlet, a rectangular frame and a discharge port are provided between the two connecting seats, and a filtering mechanism is inserted into the rectangular frame. Although this type of chip liquid filtering device can remove the filter screen to clean it, thereby achieving the effect of quickly disassembling the filter screen for cleaning. However, for this type of chip liquid filtering device, when the filter screen becomes clogged and fails, the cleaning process of the existing device is relatively complicated, and multiple components need to be disassembled for cleaning, resulting in cumbersome maintenance work, increasing the difficulty of operation and maintenance time. At the same time, there is a lack of an automated cleaning mechanism, requiring frequent manual intervention, and unable to achieve efficient automatic cleaning, which affects the continuous operation capability of the equipment. Therefore, improvements are needed. Utility Model Content

[0028] Working principle: The cutting fluid generated by the chain pin processing can enter the casing 1 through the liquid inlet hopper 2. It should be noted here that the amount of cutting fluid entering should not be too much to avoid filling the casing 1 and causing the surface of the observation window 11 to be submerged by the cutting fluid and lose the observation function. The cutting fluid then passes through the filter 6, at which time the metal impurities in the cutting fluid can be filtered out, and finally the filtered cutting fluid is discharged from the liquid outlet pipe 3. After the filtration is completed, the motor 4 is turned on, and the motor 4 can then drive the shaft 5 to rotate, and the shaft 5 can then drive the filter 6 to rotate. At this time, by rotating the filter 6 and utilizing the centrifugal force, the metal impurities on the filter 6 can be thrown out or thrown to the side, so that processing can continue, and then this is repeated until the filter 6 is completely blocked and fails. After the filter 6 fails, the worker The staff can press the pressure handle 9 downward, and the pressure handle 9 can then drive the slide bar 7 to move, and the slide bar 7 can then drive the scraper 8 to move downward until the scraper 8 is close to the filter screen 6. Then, during the rotation of the filter screen 6, the stains on the surface can be blocked by the scraper 8 and thus accumulated together. In this way, when maintaining the filter screen 6 in the future, the staff only needs to open the casing 1 to clean the accumulated stains on the surface of the filter screen 6, thereby improving the maintenance efficiency. After loosening the pressure handle 9, due to the elastic force of the spring 10, the spring 10 can drive the pressure handle 9 to move upward, and the pressure handle 9 then drives the slide bar 7 to move, and the slide bar 7 then drives the scraper 8 to reset. The utility model drives the rotating shaft 5 and the filter screen 6 to rotate by the motor 4, and utilizes the centrifugal force to clean the metal impurities on the surface of the filter screen 6, thereby realizing automation. The initial cleaning process reduces manual intervention and improves cleaning efficiency. After the filter 6 becomes clogged and fails, a mechanical cleaning structure of a pressure handle 9 and a scraper 8 is designed, so that the staff can clean the stains on the surface of the filter 6 by a simple pressing operation. This design makes subsequent maintenance work more convenient. It only needs to open the housing 1 to clean it, which greatly improves maintenance efficiency. Through periodic automatic cleaning and auxiliary cleaning of the mechanical scraper 8, the clogging frequency of the filter 6 is reduced, thereby extending the service life of the filter 6 and reducing the frequency and cost of replacing the filter 6. Through the observation window 11, the staff can observe the working status of the filtration inside the housing 1. When the filter 6 fails or in other situations, manual intervention maintenance can be carried out in time. At the same time, if the observation window 1 1. If there is too much dust on the outer surface of the machine, the staff can also push the handle 14 to control the movement of the vertical rod 12. The vertical rod 12 can then drive the scraper 13 to rub the surface of the observation window 11. At this time, the observation window 11 can be cleaned. By setting the observation window 11, the staff can monitor the working status of the filter device at any time, find out the failure of the filter 6 or other abnormal conditions in time, and perform manual intervention and maintenance to ensure the normal operation of the filter device. The design of the observation window 11 makes it unnecessary to frequently open the casing 1 to check the internal status of the equipment, which simplifies the operation process and improves work efficiency. By setting the controllable vertical rod 12 and the scraper 13, the staff can easily clean the dust on the surface of the observation window 11, maintain a good field of view, and avoid the influence of dust accumulation on the observation effect.Improve the use convenience of the equipment. The cleaning function of the observation window 11 ensures that the equipment always maintains a clear monitoring field of view during operation, making equipment maintenance more timely and effective, and reducing maintenance delays or misoperation caused by unclear observation.
