Cutter row used for reverse turning of end face on vertical lathe

Abstract

The invention belongs to the technical field of cutter rows, and particularly relates to a cutter row used for reverse turning of the end face on a vertical lathe. The cutter row is characterized by comprising a cylindrical cutter row rod with the side face provided with an installing positioning plane, a cylindrical cutter row middle part fixedly arranged at the lower end of the cutter row rod and forming a concentric step shape with the cutter row rod, a cylindrical cutter row bottom part fixedly arranged at the lower end of the cutter row middle part and forming a non-concentric step shaft shape with the cylindrical cutter row middle part, and a cutter arranged on the side face of the cylindrical cutter row bottom part. A transition circular bead is arranged at the connecting position of the cylindrical cutter row bottom part and the cylindrical cutter row middle part. The cutter row rod, the cutter row middle part and the cutter row bottom part are integrally formed. The cutter row is high in stress strength, good in anti-knock performance and low in manufacturing cost, safety is achieved during using, the quality of machined products can be guaranteed, and the machining efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of vertical lathe parts processing, and in particular relates to a cutter row used for reverse turning end faces of vertical lathes. Background technique [0002] During the processing of parts on the vertical lathe, in order to ensure the processing quality, that is, to ensure the coaxiality under normal circumstances, one-time clamping is often adopted, which will cause some processing surfaces to be difficult to process from the tool feed direction, so the processing of these surfaces Processing requires reverse turning, that is, moving the tool from far to near for processing. However, due to the large processing surface of some parts, the overhang of the tool should be increased correspondingly when reverse turning, which will generate a greater impact on the knife row, and the knife row is easy to vibrate, and the wall thickness on the stressed side is less likely to cause cracking Phenomenon, the fla...
