[0002] A cylindrical grinding machine is an important machining equipment, mainly used for machining the outer surfaces and shoulder end faces of workpieces with cylindrical, conical or other shaped generatrix surfaces. The working principle of a cylindrical grinding machine is that the workpiece is supported between the two centers of the headstock and the tailstock, and is driven by the indexing plate of the headstock to rotate for circular feed motion. The grinding wheel is installed on the main shaft and rotates for grinding, so that the outer cylindrical surface of the workpiece can be accurately machined. For workpieces or metal parts with higher hardness, the effect of the grinding machine is particularly prominent. When the cylindrical grinding machine grinds, coolant is sprayed while grinding, and the debris and waste during grinding will be washed away by the coolant and collected centrally.

[0003] After collecting the coolant and waste, by adopting the method of natural sedimentation, the waste is not easy to take out. Some devices filter the waste. Although this method can separate the waste from the coolant, the waste falls simultaneously, and the interaction between them easily blocks the filter screen, affecting the filtering efficiency, and the coolant cannot be reused, resulting in poor economic benefits. Therefore, to solve the above problems, this application provides a waste collection device for a cylindrical grinding machine. Utility Model Content

[0028] The lower wall of the filter tank 12 is provided with a filter screen 22, and the filter tank 12 is communicated with the water collection tank 13 through the filter screen 22. A motor 18 is arranged inside the base 1, and the operation of the motor 18 is controlled by an external controller. The rotating shaft of the motor 18 is coaxially and fixedly connected with a rotating rod 17. The rotating rod 17 penetrates through the water collection tank 13 and the filter screen 22 and is rotatably connected to both of them. The connection between the rotating rod 17 and the water collection tank 13 needs to be sealed to avoid affecting the normal operation of the motor 18.
