Abstract

The invention relates to a multifunctional robot wrist with a replaceable end actuator. The multifunctional robot wrist is aimed at solving the problems that in the prior art, most robot wrists are connected with end actuators, so that the function that one wrist drives various end actuators can not be achieved, manufacturing cost is high, and using is inconvenient. The multifunctional robot wrist comprises an outer power output mechanism, a middle locking and unlocking mechanism, an inner power output mechanism and a tool mechanism. The outer power output mechanism and the middle locking and unlocking mechanism are sequentially arranged on the inner power output mechanism from outside to inside in a sleeving mode. The tool mechanism is installed at the power output end of the outer power output mechanism, the power output end of the middle locking and unlocking mechanism and the power output end of the inner power output mechanism. The multifunctional robot wrist is applied to the field where end actuators need to be replaced and actuators need to be locked.

Description

technical field [0001] The invention relates to a robot wrist with a replaceable end effector, in particular to a multifunctional robot wrist with a replaceable end effector. Background technique [0002] The robot wrist has been widely used in industrial robots, and it plays an important role in industrial production. In order to meet different job requirements, the functions of robot end effectors are often different. In order to maximize production efficiency and reduce costs, a robot wrist should be able to drive a variety of end effectors. In order to achieve the above goals, the robot wrist needs to be docked and locked with different end effectors driven by the mechanical arm. At the same time, the robot wrist also needs to provide a certain amount of power input for the end effector to facilitate the operation of the end effector. Many current robot wrists are connected to end effectors, which cannot realize the function of driving multiple end effectors with the ...
