Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a device for filtering grinding oil in grinding machines. Background Technology

[0002] A grinding machine is a precision machine tool that uses an abrasive wheel to grind the surface of a workpiece. It generally consists of main components such as a bed, worktable, grinding wheel head, headstock, and tailstock. The grinding wheel rotates at high speed and contacts the workpiece surface to generate a cutting action, removing excess material from the workpiece surface and thus processing the workpiece. During the grinding process, in order to reduce grinding temperature, reduce grinding wheel wear, and improve machining quality, cutting oil is usually used to cool and lubricate the grinding area. Therefore, a large amount of workpiece debris will be mixed in with the cutting oil, which requires a filtration device to filter out the impurities in the cutting oil to prevent the impurities from affecting the grinding of the workpiece.

[0003] In existing filtration devices, the sieve plates or filter elements used for filtration have relatively simple structures and generally only perform filtration once. This results in poor filtration performance, making it impossible to completely remove impurities from the grinding oil. At the same time, the filtered impurities can easily clog the sieve plates and other structures, reducing filtration efficiency. Utility Model Content

The outer surface of the oil inlet pipe 7 is rotatably connected to the driven wheel 5. An oil outlet pipe 8 is fixedly connected to the lower surface of the housing 1.

[0025] A collection box 9 is fixedly connected to the right surface of the outer casing 1. A cleaning motor 10 is fixedly connected to the right surface of the collection box 9. A rotating shaft 11 is fixedly connected to the output end of the cleaning motor 10. The outer surface of the rotating shaft 11 is rotatably connected to the collection box 9. A spiral blade 12 is fixedly connected to the outer surface of the rotating shaft 11. A cleaning brush 13 is fixedly connected to the side of the spiral blade 12 away from the rotating shaft 11. The outer surface of the cleaning brush 13 is in contact with the filter barrel 6. A collection drawer 14 is movably provided at the bottom of the collection box 9 to facilitate the collection of large particles of impurities for unified processing by workers. A guide plate 15 is fixedly connected to the inner surface of the outer casing 1 to facilitate the flow of grinding oil splashed out by the filter barrel 6.

[0026] Working principle: Grinding oil enters the filter barrel 6 through the oil inlet pipe 7. The drive motor 2 drives the transmission wheel 3 to rotate, and the transmission wheel 3 drives the driven wheel 5 to rotate through the belt 4, thereby driving the filter barrel 6 to rotate. Under the action of centrifugal force, the grinding oil inside is thrown out through the filter holes set on the outside of the filter barrel 6, while large particles of residue remain on the inner wall of the filter barrel 6. The cleaning motor 10 drives the rotating shaft 11 to rotate, thereby driving the spiral blade 12 to rotate, which in turn drives the cleaning brush 13 to rotate and sweep the residue off the inner wall of the filter barrel 6 to prevent clogging of the filter holes on the side wall of the filter barrel 6. At the same time, the swept residue is transported by the cleaning brush 13 into the collection drawer 14 inside the collection box 9 for collection. The grinding oil thrown out of the filter barrel 6 flows into the mounting frame 16 through the guide plate 15, is filtered by the filter cloth 18, and is finally discharged from the oil outlet pipe 8 for recycling. While the grinding oil is being filtered by the filter cloth 18, the magnetic frame 17 can adsorb the residue inside the grinding oil, improving the filtration effect of the grinding oil.
