Cutting device for metal casting machining of hydraulic vehicle

The utility model relates to the technical field of metal casting machining, and discloses a cutting device for metal casting machining of a hydraulic vehicle, which comprises a box body, a filter plate is fixedly mounted at the upper end of the box body, filter holes are formed in the filter plate, the filter holes are communicated with the box body, and a support frame is fixedly mounted at theupper end of the box body. The metal casting is fixed through the clamping plate by starting the push rod motor, then the cutting machine is started to cut the metal casting, during cutting, the protective cover is attached to the metal casting through the spring, then the first valve is opened, and therefore the metal casting is cut in cooperation with cutting liquid. Through the arrangement of the protective cover, the cutting fluid can be prevented from sputtering and polluting the working environment, the cutting fluid and chippings can be filtered through the filter plate and the filter holes, the cutting fluid i
