    Abstract: The present invention provides a kind of permanent magnetic lifting device, which has: a housing, at the bottom of which is a clamping surface for clamping objects; fixed magnet(s), set in housing relatively fixed to housing; a turnable magnet, set in housing relatively turnable to fixed magnet. When turnable magnet is in the first position relative to fixed magnet, the magnetic force generated by fixed magnet and turnable magnet to clamping surface is zero magnetic force; when turnable magnet is in the third position relative to fixed magnet, the magnetic force generated by fixed magnet and turnable magnet to clamping surface is the maximum magnetic force. The permanent magnetic lifting device also has a positioning mechanism for second position to position the turnable magnet in the second position relative to fixed magnet, fixed magnet and turnable magnet generate trial clamping magnetic force to clamping surface for clamping objects on trial.

    Abstract translation: 本发明提供一种永磁提升装置,其具有:壳体,其底部是夹紧物体的夹紧面; 固定磁体,设置在与壳体相对固定的壳体中; 固定在壳体内的可转动磁体可相对转动到固定磁体。 当可转动磁体相对于固定磁体位于第一位置时,由固定磁体和可转动磁体产生的夹紧磁力对零位磁力; 当可转动磁体相对于固定磁体位于第三位置时,由固定磁铁和可转动磁体产生的夹紧磁力对夹紧表面是最大的磁力。 永磁提升装置还具有用于第二位置的定位机构,用于将可转动磁体相对于固定磁体,固定磁体和可转动磁体定位在第二位置,以将试件夹紧磁力产生到夹紧表面,用于在试验中夹紧物体。
