A three-axis linkage mechanical arm for boring processing

Abstract

The invention discloses a three-axis linkage boring mechanical arm which comprises a cylindrical tool handle and a tool. The tool is installed in a cutting segment at the front end of the tool handle. The three-axis linkage boring mechanical arm is characterized in that a radial feed control segment for controlling tool radial feed, a circumferential rotation control segment for controlling the circumferential rotation of the tool cutting segment, and an axial telescopic control segment for controlling axial telescopic movement of the tool cutting segment are formed at the rear end of the cutting segment of the tool handle sequentially backwards, and a tool stable supporting device for supporting in a machined hole is arranged on the tool handle. The three-axis linkage boring mechanical arm can achieve independent boring and has the advantages of being large in boring range, wide in applicability, high in machining precision and the like.

Description

technical field [0001] The invention belongs to the field of boring processing of complex hole wall shapes, and in particular relates to a three-axis linkage mechanical arm for boring processing. Background technique [0002] Boring is the internal diameter cutting process of enlarging a hole or other circular profile with a tool. Its applications generally range from semi-roughing to finishing. The tool used is usually a boring tool or boring bar. Boring is the further processing of forged, cast or drilled holes, which is a kind of boring method. Boring can enlarge the aperture, improve precision, reduce surface roughness, and can better correct the deviation of the original hole axis. [0003] The common boring tool structure generally includes a tool handle and a tool arranged at the front end of the tool handle, and the rear end of the tool handle is installed on the machine tool, and the machine tool is used to provide power for boring processing. However, for some si...

Problems solved by technology

However, for some situations that are not suitable for processing by machine tools, such as the technical transformation of some installed larger equipment that requires reaming and boring processing, it is difficult to use existing processing equipment to achieve processing

[0004] In addition, the existing boring tools have limited boring processing performance. For deep hole boring processing with a depth greater than 6 times the diameter, and some more complex structures such as spiral partition grooves, straight grooves, inclined grooves, and arc grooves , screw thread, helical surface, arc surface, local expansion of the inner hole, etc., it is also difficult to guarantee the accuracy and processing efficiency
