AI Technical Summary

Technical Problem

Existing modular tools are heavy and cannot meet the processing requirements of low-power machine tools. Dynamic balance is difficult to control, which affects the processing life and quality, and the material utilization rate is low.

Method used

A honeycomb structure is set up inside the tool bar, and multiple hexagonal holes are connected into a hollow grid shape. Combined with the shell and solid connection part, it ensures rigidity and strength and reduces the weight of the tool.

Benefits of technology

The tool weight is reduced, suitable for more low-power machine tools, improving dynamic balance control, extending processing life, reducing material waste and reducing costs.

Abstract

A tool arbor and cutting tool, comprising a shank, a locking portion at one end of the shank, and a terminal portion at the other end, characterized in that a housing is provided between the locking portion and the terminal portion; and a honeycomb structure within the housing, the honeycomb structure being formed by connecting a plurality of hexagonal holes, with a support wall provided between two adjacent hexagonal holes, the support wall being connected between the locking portion and the terminal portion and parallel to the centerline of the shank, with the support walls between three adjacent hexagonal holes intersecting to form an interconnecting portion. While meeting the rigidity and strength requirements for tool machining, the present invention significantly reduces the weight of modular tools, reduces machine tool power consumption, facilitates tool dynamic balance control during tool machining, and improves tool machining life and quality.
