Discarded type sleeve cutterhead

Abstract

The invention provides a discarded type sleeve cutterhead. The discarded type sleeve cutterhead comprises a cutterhead body, a cutter handle, cutter clamps and cutter blades; a transitional bevel edgeis arranged between the cutterhead body and the cutter handle; the end face of the cutter handle is provided with a first hole groove used for mounting a milling cutter handle, and a groove is formedin the end face of the cutter handle, and the milling cutter handle and the groove are mounted in a matched mode; the end face of the cutterhead body is provided with a second hole groove for accommodating cutting chippings, and the bottom end of the second hole groove is provided with a third hole groove for avoiding interference of parts; the end face of the cutterhead body is provided with four protrusion parts, the cutter blade is locked and fixed to the corresponding pair of adjacent protrusion parts, the cutter clamps are mounted on the other pair of adjacent protrusion parts, and the cutter blades are locked and fixed to the cutter clamps; and an included angle of the cutting faces of the adjacent cutter blades is 90 degrees, the cutting edges of the cutter blades are located on the same plane and perpendicular to the axis of the cutterhead body. The discarded type sleeve cutterhead adopts fixed and floating blade edge design, the cutter blades fixed to the cutterhead body canbear large cutting force, the size cannot be adjusted, and the cutter clamps can avoid the situations of vibration edge, poor finish degree and the unstable workpiece size due to uniformity of blank oxide skin by adjusting the size.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a discarded set cutter head. Background technique [0002] The existing blades are mainly fixed on the handle by welding. After using for a period of time, once the cutting edge of the blade is worn out, the whole blade can no longer be used, which wastes resources; high. [0003] Ordinary sets of cutters have a 4-blade symmetrical structure. When the machining allowance is large, due to the instability of the rough blank, it is easy to cause knife vibration, resulting in poor finish and unstable dimensions of the processed outer circle. Contents of the invention [0004] The object of the present invention is to provide a discarded cutterhead which can adjust the blade by an adjustable holder to avoid edge vibration. [0005] In order to achieve the above object, the present invention proposes a discarded cutter head, including a cutter head, a knife handle, a knife holder and a blade; a tr...
