Description

Technical Field

[0002] The divertor module is an important component of the nuclear fusion device, which works in a vacuum chamber with nuclear radiation and high temperature. Therefore, when the divertor module needs to be maintained, the experimenter cannot perform maintenance directly at its workstation, but needs to dismantle it and move it out of the vacuum chamber for maintenance. After the maintenance is completed, it is moved and installed to the original workstation. Generally, the fasteners on the divertor module are removed and installed by a mechanical arm equipped with a wrench tool, but the connection strength of the fasteners of the target plate of the divertor module is much stronger than that of the fasteners at other positions of the divertor module. Using a general-purpose mechanical arm in the vacuum chamber to loosen or tighten the fasteners of the target plate will cause the mechanical arm to be subjected to a large torque. After being subjected to the torque, the mechanical arm is prone to reduce its accuracy, affecting subsequent work and reducing its service life. Summary of the invention
