Abstract

The invention discloses an ultrasonic vibration drill hole tail end actuator which comprises a main shaft unit, an ultrasonic knife handle unit and a feeding unit. The ultrasonic vibration drill hole tail end actuator overcomes the defects of a traditional drilling technique, an ultrasonic vibration drilling technique is utilized for conducting drilling on aluminum alloy, titanium alloy, carbon fiber composite materials and other materials difficult to process through robots, especially for conducting drilling on small holes with the diameter being less than 6 mm, and the machining quality and efficiency are improved. A radial wireless transmission mode is adopted for the tail end of a rotor to transmit ultrasonic signals, interference with oil cylinder cutter movement and spindle rotation does not occur, a copper electrode penetrates through a spring rod inner hole to be connected with a knife handle inner copper electrode in cooperation with an elastic pin shaft in the knife assembling process so as to transmit ultrasonic signals, a carbon brush does not need to be replaced, device durability is improved, all power transmission devices are arranged in a main shaft, and a robot can achieve multi-angle drilling. Multiple ultrasonic knife handles can be replaced quickly, and machining efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of robot hole making, and in particular relates to an ultrasonic vibration drilling end effector. Background technique [0002] With the development of modern industry, the requirements for safety and service life of aircraft are getting higher and higher. According to statistics, 12-30% of aircraft failures are caused by fatigue damage, and most of the fatigue damage accidents are caused by the fatigue of the connecting parts. Therefore, it is of great significance to improve the processing efficiency and quality of connecting holes. Since the 1950s, the United States, the former Soviet Union and other countries have begun to develop automatic drilling and riveting equipment, and applied it to aircraft production lines. The robot hole making system belongs to the category of CNC drilling and riveting equipment. It uses industrial robots to drive the end effector to move in a large range to carry out drill...
