AI Technical Summary

Technical Problem

Existing boring tools for square holes require multiple adjustments for tool movement, leading to difficulty in controlling square hole size accuracy and prone to errors during the complex operation of boring square holes.

Method used

A combined tool design with a telescopic sleeve assembly, square hole filing assembly, and a boring tool fixing head, allowing for integrated boring and filing functions, enabling the formation of a square hole in one operation using a single set of tools without mid-process changes.

Benefits of technology

Ensures uniform hole size during the filing process by simultaneous operation of right-angle filing tools, simplifying the processing flow and improving accuracy by eliminating the need for multiple adjustments, thus enhancing the precision of square hole formation.

Abstract

The invention relates to the technical field of boring cutters, in particular to a boring cutter for square hole machining, which comprises a boring shaft rod, a telescopic sleeve assembly is arranged outside the boring shaft rod, and a square hole filing assembly is arranged below the telescopic sleeve assembly; the boring and filing integrated tool system has the beneficial effects that the telescopic sleeve assembly, the square hole filing assembly and the boring cutter fixing head are matched to form the boring and filing integrated tool system, and the boring cutter head and the boring cutter fixing head rotate to conduct round hole boring firstly; then, the mounting disc moves downwards under the cooperation of the first sleeve and the second sleeve to enable the right-angle filing cutters to be symmetrically distributed on the outer side of the boring cutter head, the workbench of the boring vehicle body continues feeding to file the bored round hole, feeding and retreating repeated operation is continuously conducted, and meanwhile the right-angle filing cutter frame expands outwards point by point; a square hole with the side length equal to the diameter of a round hole can be filed, the whole process from round hole boring to square hole filing can be completed through one set of cutter, and the cutter does not need to be replaced midway.
