Adjustable auxiliary knife rest for inner diameter knife

Abstract

The invention relates to the technical field of turning tools, in particular to an adjustable auxiliary knife rest for an inner diameter knife. The adjustable auxiliary knife rest for the inner diameter knife comprises a knife sleeve and a knife apron, wherein an inner hole is machined in the knife sleeve and used for installing the inner diameter knife; the knife apron is connected with the knifesleeve; a lifting mechanism is arranged between the knife apron and the knife sleeve; and a lifting mechanism is used for driving the knife sleeve to move up and down in a reciprocating mode relativeto the knife apron. According to the adjustable auxiliary knife rest for the inner diameter knife, the knife sleeve is driven by the lifting mechanism to do reciprocating motion in the vertical direction relative to the knife apron, lifting of the knife sleeve is achieved, the inner diameter knife is driven to move up and down, and therefore, the height of the working part of the inner diameter knife is adjusted to be aligned with the center line of a main shaft. Compared with a traditional technology that a knife cushion plate is adopted for adjustment, the adjustable auxiliary knife rest for the inner diameter knife has the advantages that adjustment can be conducted through one-time clamping so as to meet the mounting requirement, the knife setting time is shortened, the labor intensity of an operator is reduced, the working efficiency is enhanced and the working quality is improved.

Description

technical field [0001] The invention relates to the technical field of turning tools, in particular to an adjustable inner diameter tool auxiliary tool holder. Background technique [0002] Cutting tool is an indispensable and important tool in cutting process. No matter it is ordinary machine tool or advanced numerical control machine tool (NC), machining center (MC) and flexible manufacturing system (FMC), it must rely on tool to complete cutting process. The development of cutting tools has an important impact on improving productivity and processing quality. [0003] The inner hole turning tool is installed on the lathe tool post by the clamping part of the tool bar. However, due to the installation requirements, when the tool is reprocessed, the machine slide plate is easy to touch the soft limit. However, the conventional tool sleeve needs Adding a backing knife plate to raise the tool tip so that its height is on the center line of the main shaft to meet the installa...
