Abstract

The invention discloses a robot and a large-torque rotatable joint power device thereof. The large-torque rotatable joint power device is mounted on a rotating joint of a pedestal or a waist arm or alarge arm or a small arm or a wrist part of the robot. The large-torque rotatable joint power device comprises a piston capable of doing reciprocating motion and a guide part connected with the piston; a main power system and a resetting power system are respectively arranged at the piston end and the guide part end; the guide part is connected with a piston rod; and the axial reciprocating motionof the guide part is converted into the radial rotation of the piston rod. The large-torque rotatable joint power device is used for converting the returning thrust into rotation torque force; when the large-torque rotatable joint power device is applied to the robot joint part and is used for replacing the servo motor, so that the energy is saved, and the pollution is low.

Description

technical field [0001] The invention relates to a robot, in particular to a robot using a high-torque rotatable joint power device. Background technique [0002] A common rotatable joint power device uses power to make the rotating member rotate in the radial direction, and power is also required for reverse reset. The force generated by the radial rotation can be used as the power source of the rotating shaft. [0003] The invention with the patent No. 201410395121.0 discloses a non-powered rotary clamp, which includes a rotary cylinder piston, cylinder body, nitrogen spring, cylinder end cover and compression arm. Several nitrogen gas springs are placed around the piston rod A on the upper surface of the large end. This invention utilizes high-pressure sealed nitrogen gas springs to propel and clamp the workpiece through the rotation of the rotary oil cylinder piston, without additional external power source, and relies on nitrogen gas springs to maintain pressure and cl...
