Abstract

The invention discloses a drilling terminal end actuator used for industrial robots, comprising a spindle unit, a feed unit and a supporting unit. The spindle unit comprises a precise spindle head, a spindle motor and drive, an ER spring collet, a tool holder, a tool, a synchronous belt and a pulley; the feed unit comprises a linear ball bearing guide bushing and a special axis, a screw pair, a feed motor and drive, the synchronous belt and the pulley; and the supporting unit comprises a pedestal, a shaft seat, a precise spindle head support, a cylinder support, a pressure head pipe shell, a presser foot, a front plate, a rear plate, an electromagnetic valve connecting plate, a spindle motor connecting plate and a limit switch connecting plate. The spindle unit realizes the adjustable cutting speed of the drill, the feed unit realizes the adjustable feed speed and feed travel of the drill, and the supporting unit ensures the whole stiffness of the terminal end actuator. The drilling terminal end actuator can constitute a flexible drilling and cutting system by being combined with the robot for use, which can improve the drilling efficiency and accuracy, improve the drilling quality and reduce the labor duplication of workers.

Description

technical field [0001] The invention relates to the field of robot drilling, more particularly, to a drilling end effector suitable for industrial robots. Background technique [0002] Hole processing plays an important role in aviation manufacturing. It has been reported in the literature that about 40 million holes are drilled and processed each year on an assembly line of a wing. Traditional manual drilling involves heavy workload, boring process, low drilling efficiency, difficulty in ensuring consistency in hole accuracy and quality, and high manpower and material costs for mass production. With the improvement of the robot's position accuracy, load capacity and the development of position and stiffness compensation technology, the robot can be used as an efficient mobile platform, and combined with the drilling end effector, a flexible drilling system can be formed, which improves productivity and It embodies the concept of lean system. The end effector is a key part...
