Cutter head grinding device

Abstract

The invention discloses a cutter head grinding device. The cutter head grinding device comprises a lathe bed, a workpiece box body, a stand column, a B-axis box body, a grinding wheel box body and a relative motion driving mechanism. The workpiece box body is arranged on the lathe bed and internally provided with a workpiece rotating shaft, wherein the workpiece rotating shaft is used for allowinga workpiece to be fixedly mounted thereon, and the workpiece rotating shaft is rotatably arranged in the workpiece box body. The stand column is arranged on the lathe bed. The B-axis box body is arranged on the stand column and internally provided with a grinding wheel box body swinging shaft, wherein the grinding wheel box body swinging shaft is used for allowing the grinding wheel box body to be fixedly mounted thereon, and the grinding wheel box body swinging shaft is rotatably arranged in the B-axis box body. The grinding wheel box body is arranged on the B-axis box body and provided witha grinding wheel rotating shaft, wherein the grinding wheel rotating shaft is used for allowing a grinding wheel to be fixedly mounted thereon; the grinding wheel rotating shaft is rotatably arrangedin the grinding wheel box body; and the grinding wheel box body can rotate relative to the stand column, and the rotation axis direction is perpendicular to the grinding wheel rotating shaft. The relative motion driving mechanism is arranged on the lathe bed and used for driving the workpiece box body to move relative to the stand column. By means of the cutter head grinding device, machining efficiency and machining precision are improved.

Description

technical field [0001] The invention relates to the technical field of machine tools, in particular to a cutter head grinding device. Background technique [0002] At present, the processing of the cutter head generally adopts the method of slow wire cutting. Slow wire cutting is a kind of wire electric discharge cutting. By using a continuously moving thin metal wire (called an electrode wire) as an electrode, the workpiece is subjected to pulse spark discharge to etch the metal and cut into shape, and then processed into a cutter head. [0003] However, the cutting time of slow wire cutting is long, and the cutting precision is not high, which leads to low processing efficiency and processing precision of the cutter head. [0004] Therefore, how to improve the machining efficiency and machining accuracy of the cutter head has become a technical problem to be solved urgently by those skilled in the art. Contents of the invention [0005] The object of the present inven...
