Abstract

The invention discloses a robot end effector and a robot, belonging to the technical field of grinding and processing. The end effector of the robot is used for grinding and processing the workpiece, including the execution tool, the rotary unit, the rotation unit, the ultrasonic vibrator and the constant force control component, wherein, one end of the rotary unit is connected with the execution tool, and the rotary unit is used to drive the execution tool to rotate Movement; the rotary unit is used to drive the rotary unit to perform rotary motion, and the direction of the rotary motion is not in the same direction as the rotary motion direction; the ultrasonic vibrator is connected to the rotary unit, and the ultrasonic vibrator is used to drive the rotary unit and the execution tool to vibrate axially; constant force control components Used to maintain a constant contact pressure between the implement and the workpiece. A robot includes the above-mentioned robot end effector. The robot end effector provided by the invention simplifies the structure, reduces the difficulty of control, and improves the processing quality and work efficiency through structural design and constant contact pressure control.

Description

technical field

[0001] The invention relates to the technical field of grinding and processing, in particular to a robot end effector and a robot. Background technique

[0002] At present, the overall processing of the aircraft body and large parts is the most important and most difficult process in the coating process for civil aircraft manufacturers and maintenance plants. The defects generated by processing will directly reflect the final appearance. The surface finish quality largely determines the final paint quality and effect of the aircraft. At present, hand-held pneumatic grinding machines are generally used in the aircraft manufacturing process, which completely relies on human experience to control the grinding force, angle, and time. There are problems such as poor processing quality stability and low efficiency, especially when processing composite materials. The reliability of the fuselage is difficult to guarantee, and the processing A large amount of dust in...
