Abstract

The invention discloses a robot buffering foot with adjustable pretightening force. The robot buffering foot comprises a foot bottom supporting rod, a foot basic joint, a pretightening adjustment adapter sleeve, a pretightening adjustment buffer sleeve, and an adapter sleeve anti-loosening spring, wherein the foot bottom supporting rod performs a supporting and connecting function; the foot basicjoint is cooperated with the foot bottom supporting rod through a foot end buffer spring; meanwhile, the top of the foot basic joint is connected with a power source; the pretightening adjustment adapter sleeve is arranged on the lower part of the food basic joint in a sleeving manner and is cooperated with the foot basic joint through a thread; the pretightening adjustment buffer sleeve is arranged on the foot bottom supporting rod in a sleeving manner; the adapter sleeve anti-loosening spring is positioned in the pretightening adjustment adapter sleeve for carrying out loosening prevention;after the lower part of the foot bottom supporting rod penetrates through the adapter sleeve anti-loosening spring and the pretightening adjustment adapter sleeve, the foot bottom supporting rod is connected with a foot bottom ball through a foot bottom ball connecting sleeve; and the outer circumference of the upper part of the foot bottom supporting rod is provided with one circle of first groove in which a plurality of supporting rod lubrication balls are arranged. The robot buffering foot has the characteristics of reliable structure, good buffering and vibration resistance ability, adjustable pretightening force and convenience in maintenance, adjustment and replacement.

Description

technical field [0001] The invention is designed in the field of robots, and specifically relates to a robot buffer foot with adjustable pretightening force. Background technique [0002] As an important branch of land bionic robots, multi-legged robots are increasingly favored by scientists and mechanical workers from all over the world. At present, relatively mature multi-legged robot solutions are mammalian quadruped robots and insect-like hexapod or eight-leg robots. Most of these land bionic robots work in a complex environment, especially in the field or under complex road conditions. During the movement of the robot, its feet will inevitably collide with the hard ground, and the resulting vibration will affect its motion accuracy. At the same time, long-term collision impact will also affect the life of the robot. [0003] Chinese patent CN 109774814 A discloses a multi-legged walking robot foot structure that realizes ground contact feedback, including: a front she...
