Problems solved by technology
However, in this method, when the cam bar moves along the edge of the template, it is necessary to make the grinding wheel uniformly perpendicular to the curve of the edge of the template. It is difficult to ensure that the curve of the grinding wheel and the edge of the formwork are exactly the same while the camber rod is attached
Once inconsistent, the curve of the milling cutter will not match the design curve, which will eventually affect the machining accuracy of the screw, resulting in low delivery efficiency and high operating noise of the screw pump

Description
technical field [0001] The patent belongs to the technical field of screw pump rotor processing, in particular to a screw pump rotor milling cutter grinder. Background technique [0002] At present, the profile of the rotor of the screw pump is mostly processed by milling, and the processing accuracy of milling depends largely on the accuracy of the milling cutter head. At present, when the milling cutter head wears out after a period of use and needs to be re-sharpened, it is done by profiling. Specifically, by placing a positioning rod against the side edge of a fixed template, This template is consistent with the molded line of the milling cutter, so that the positioning rod and the grinding wheel are linked through a movable tool holder, and the cam lever moves along and close to the side edge of the template, so that the grinding wheel also moves along the same curve , to process the milling cutter curve consistent with the template curve. However, in this method, whe...
