Abstract

The present invention relates to an integrated joint, in particular to an integrated joint of an oil running oscillating cylinder. The problems that an existing robot joint is insufficient in drivingtorque and too small in loading torque are solved. The integrated joint of the oil running oscillating cylinder comprises a first round nut, a left actuator, a left cylinder cover, a cylinder body, aright actuator, a right cylinder cover, a second round nut and an output shaft. The cylinder body sleeves the middle of the output shaft, the first round nut and the left actuator and the left cylinder cover sleeve the left end of the output shaft in order from left to right, and the second round nut, the right actuator and the right cylinder cover sleeves the right end of the output shaft in order from right to left. The present invention belongs to the field of robots.

Description

technical field [0001] The invention relates to an integrated joint, in particular to an integrated joint of an oil traveling swing cylinder, which belongs to the field of robots. Background technique [0002] Nowadays, the joint drive of robots is mainly divided into two modes: motor drive and hydraulic drive: the motor-driven robot joint has the advantages of simple structure, easy control, and flexible movement, but its power density is low and the load is low; hydraulically driven motion joints are mostly Linear cylinders are widely used due to the advantages of simple structure, reliable sealing, and high power density, but they need to design a transmission mechanism to convert the linear motion of the hydraulic cylinder into the rotary motion of the joint. At present, most hydraulically driven robots use linear cylinders. The transmission mechanism of hydraulic cylinder plus connecting rod or rack and pinion realizes the conversion of motion, and the oil passage throu...
