Cutter body structure with replaceable turning portion

Abstract

The invention discloses a cutter body structure with a replaceable turning portion, and belongs to the technical field of machine tool cutters. The cutter body structure with the replaceable turning portion comprises a cutter handle. A left deep connecting hole and a right deep connecting hole are formed in the cutter handle. A cutter head is arranged at the front end of the cutter handle, a firstconnecting groove and a second connecting groove are formed in the upper portion of the cutter head, a locating groove is formed in the lower portion of the cutter head, and a left fastening groove and a right fastening groove are formed in the groove bottom surface of the locating groove. One end of the cutter handle is arranged in the locating groove. Fasteners are arranged in the left deep connecting hole and the right deep connecting hole, and the heads of the fasteners are connected to the interiors of the left fastening groove and the right fastening groove. The end of the cutter handleis connected with the groove bottom of the locating groove in a closely attached mode. The cutter body structure with the replaceable turning portion is novel in structure and clear in working principle. Compared with a conventional turning tool structure, the cutter body structure with the replaceable turning portion has the advantages that the number of cutter manufacturing consumables is reduced, the machining cost is reduced, the cutter body structure can be used and popularized, the key point lies in the fact that the cutter head can be replaced under the condition that a cutter body does not need to be disassembled when turning is conducted, the cutter head is conveniently replaced, tool setting operation does not need to be conducted, and the turning accuracy is further improved.

Description

technical field [0001] The invention belongs to the technical field of machine tools and relates to a turning tool structure, in particular to a replaceable turning part tool body structure. Background technique [0002] That is, lathe processing, which is a part of mechanical processing. Lathe processing mainly uses turning tools to turn rotating workpieces. Lathes are mainly used to process shafts, disks, sleeves and other workpieces with rotating surfaces, and are the most widely used type of machine tool processing in machinery manufacturing and repair factories. The lathe uses different turning tools or other tools to process various rotating surfaces, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, threads, groove turning grooves, end faces and forming surfaces, etc. The machining accuracy can reach IT8~IT7, and the surface roughness Ra The value is 1.6-0.8. Turning is often used to process single-axis parts, such as straight shafts, g...
