制孔末端执行器

Drilling tail end actuator

Abstract

The invention discloses a drilling tail end actuator which comprises a butt joint support assembly, a cutter revolution assembly arranged at one end of the butt joint support assembly in a rotation mode, a cutter rotation assembly arranged in the cutter revolution assembly in a rotation mode, an axial feeding assembly arranged at the other end of the butt joint support assembly and used for controlling axial feeding of a cutter, and a cutter deviation adjusting assembly arranged on the cutter revolution assembly and used for performing deviation adjustment on the cutter. The drilling tail end actuator has the advantages that the cutter deviation adjusting assembly is arranged so that the drilling tail end actuator clamps the cutter capable of machining various apertures, a cutter changing link is avoided, and drilling efficiency is improved. The cutter revolution assembly and the cutter rotation assembly are arranged so that double functions of drilling and milling holes in a screwed mode of the drilling tail end actuator are achieved. Externally exposed arrangement of the cutter deviation adjusting assembly is achieved so that transmission design among moving components is convenient, and the design difficulties of the drilling end tail actuator are reduced.
本发明公开了一种制孔末端执行器,包括对接支撑组件、转动设置在对接支撑组件一端的刀具公转组件、转动设置在刀具公转组件内的刀具自转组件、设置在对接支撑组件另一端用于控制刀具轴向进给的轴向进给组件和设置在刀具公转组件上用于对刀具进行偏心调节的刀具调偏组件。本发明的有益效果是:刀具调偏组件的设置,使制孔末端执行器夹持一把刀具可加工多种孔径,避免了换刀环节,提高制孔效率。刀具公转组件与刀具自转组件的设置,使制孔末端执行器可实现钻孔与螺旋铣孔双重功能。本发明实现了刀具调偏组件的外露布局,便于运动部件间传动设计,降低了制孔末端执行器的设计难度。
