Turning cutter head and cylindrical workpiece turning machining device

Abstract

The utility model provides a square turning cutterhead which comprises a cutterhead body and a guide cylinder which are coaxially arranged, a movable disc is arranged on the guide cylinder in a sleeved mode, a plurality of guide portions are arranged on the movable disc at equal intervals, guide grooves are formed in the guide portions respectively, the length direction of the guide grooves is not parallel to the axial direction of the movable disc, and a plurality of installation portions are arranged on the cutterhead body at equal intervals. A mounting groove is formed in the mounting part, a cutter is arranged in the mounting groove, a positioning groove is formed in the mounting part, a push block is arranged in the positioning groove, one end of two opposite ends of the push block abuts against the cutter, a guide rod is arranged at the other end of the push block, the distance between the end, abutting against the cutter, of each push block and the center shaft of the disc body is consistent, and the guide rod is correspondingly matched with the guide groove. The utility model further provides a cylindrical workpiece turning machining device which comprises the turning cutter head. The cutter bar solves the technical problems that the cutter bar on an existing cutter head is tedious in cutter adjusting operation and long in consumed time, and the technical effects that the positions of the cutters on the cutter head body can be conveniently adjusted, and it is guaranteed that the extending lengths of the cutters are consistent are achieved.
