The invention belongs to the field of
grinding devices, and particularly relates to a
flange plate
grinding device. The
flange plate
grinding device comprises a
machine frame and a grinding knife, wherein the
machine frame is provided with a positioning spigot, a rotating shaft is arranged on the
machine frame in a penetrating mode, one end of the rotating shaft is located in the positioning spigot, and the other end of the rotating shaft is connected with a motor; fan blades are further arranged on the rotating shaft, and an air collecting opening is formed in one side of one
fan blade; a knife placing groove for allowing the grinding knife to rotate is further formed in one side of the positioning spigot, a cavity is formed in the grinding knife, and a vent
pipe is arranged in the bottomof the knife placing groove and penetrates through the machine frame; one end of the vent
pipe communicates with the cavity of the grinding knife, and the other end of the vent
pipe communicates withthe air collecting opening; air holes are further formed in the grinding knife, a first air cylinder is further fixedly connected to the machine frame, and an output rod of the first air cylinder isfixedly connected with a rack; and a gear way is arranged on the machine frame, a gear is arranged between the rack and the gear way in a meshed mode, and the grinding knife is rigidly connected withthe gear. According to the scheme, the
flange plate grinding device can be used for
machining a flange plate with a taper, and is mostly used for
machining the flange plate with the taper.
