Robot drive mechanism used in high temperature vacuum environment

Abstract

The invention discloses a robot drive mechanism used in a high temperature vacuum environment, which comprises a motor frame, wherein a high-temperature motor is arranged in the motor frame, a screw is fixedly arranged on a motor shaft of the high-temperature motor, the other end of the screw is provided with a screw nut which is arranged in correspondence with the screw, the screw extends in an inner cavity of a sliding rod, and the screw nut on the screw is fixedly connected with the inner wall of the inner cavity of the sliding rod; a flange is fastened and arranged on the left side of themotor frame and matched with a groove of the motor frame; a metal corrugated pipe is sheathed outside the motor frame, a joint flange of the metal corrugated pipe is paired and hermetically connectedwith the flange, the metal corrugated pipe extends and is sheathed outside the sliding rod, the sliding rod extends out of the metal corrugated pipe, and the contact surfaces of the metal corrugated pipe and the sliding rod are hermetically and fixedly connected; and an auxiliary support mechanism is arranged outside the metal corrugated pipe. The robot drive mechanism has the advantages that thestructure is simple, and the weight is light; the work environment of inner parts is separated from the outer vacuum environment through the use of the metal corrugated pipe for seal, and the vacuum environment is effectively prevented from pollution; in addition, the drive force is large, and the locating accuracy is high.

Description

technical field [0001] The invention relates to the field of robot drive mechanisms, in particular to a linear drive mechanism of a telescopic rod type robot that can withstand an operating temperature of 150°C and does not pollute the vacuum environment. Background technique [0002] In order to cope with the energy crisis that the world will face in the future, many countries in the world are actively researching a controllable magnetic confinement nuclear fusion reaction device in recent years, which is called a tokamak internationally. The tokamak device contains an annular vacuum chamber used to accommodate fusion reaction substances. When the tokamak device is in operation, the internal components of the vacuum chamber will be damaged to varying degrees. In order to understand the degree of damage to the internal components of the vacuum chamber and determine whether the tokamak device can continue to operate, a robot that can be used to inspect and maintain the in...
