Abstract

The invention discloses a deep hole machining manipulator, which comprises an arm assembly, a working device and a control system, wherein the arm assembly can be used for at least providing axial feed and peripheral feed; the working device is fixed at the output end of the arm assembly, and is used for machining or detecting; the control system is used for controlling the feeding direction of the arm assembly and the working state of the working device; and the arm assembly comprises a fixed arm, a telescopic arm which is axially connected to the fixed arm at a single degree of freedom in a sliding way, and a rotating arm which is circumferentially connected to the telescopic arm at a single degree of freedom. Due to the adoption of the deep hole machining manipulator disclosed by the invention, deep hole machining and detecting can be performed by breaking through the limit of a deep hole aperture, the length-diameter ratio of a tool can be reduced greatly, the tool has high strength and high rigidity, the deep hole machining accuracy and surface quality can be ensured, the machining requirements of special structures such as inner splines machined in deep holes, in-hole curve structures, inner spiral grooves, and curved teeth are met, and integral machining and forming of deep hole parts having the special structures are realized.

Description

technical field

[0001] The invention relates to hole processing technology, in particular to a deep hole processing manipulator. Background technique

[0002] Traditional hole processing is generally carried out on lathes or drilling machines. By clamping tools such as drills, boring tools or reaming drills on the tool holder of the lathe or drilling machine, the processing of conventional holes such as drilling, boring and reaming can be realized. When processing deep holes, due to the limitation of the hole diameter, the tool holder is small in diameter, large in length, poor in rigidity, and low in strength. It is prone to vibration, ripples and tapers during cutting, which affects the straightness and surface roughness of deep holes. In most cases, The depth-to-diameter ratio of lower deep holes is as high as L / d≥100, such as cylinder holes, shaft axial oil holes, etc. These holes not only have a large depth-to-diameter ratio, but also require high machining accuracy and...
