Flange plate grinding device

Abstract

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.

Description

technical field [0001] The invention belongs to the field of grinding devices, in particular to a flange grinding device. Background technique [0002] The tapered flange uses a tapered short neck to strengthen the flange ring, and the small end of the tapered neck is welded together with the cylindrical shell, which increases the rotational stiffness of the flange, thereby reducing the stress in the flange and improving the performance of the flange. The gasket sealing condition is more economical and effective than increasing the thickness or diameter of the flange ring, so it is mostly used in medium and high pressure occasions. The surface of the flange needs to be ground before it can be used. At present, the grinding machine is mainly a grinding wheel grinder, which fixes the flange on the workbench and then grinds it through a sharpener. This operation can only grind a part of the flange each time, that is, Either grind the inner ring or the outside of the flange, wh...

Problems solved by technology

[0004] Although the above-mentioned patent can also grind the side of the flange while grinding the end face of the flange, because the position of the mounting plate is fixed, it can only grind the cylindrical flange to remove the burrs on the side. When grinding a tapered flange, the angle cannot be changed with the taper of the flange, and grinding cannot be performed
