Isomagnetic self-adaption positioning mechanism for multiple groups of laser tailor welded blanks

The utility model relates to laser processing positioning equipment, in particular to an isomagnetic self-adaption positioning mechanism for multiple groups of laser tailor welded blanks. The isomagnetic self-adaption positioning mechanism comprises a support, a spindle, two joint retractable arms and a plurality of magnetic force layering units, wherein the spindle is rotationally mounted on the support, one end of the spindle extends out of the support and is connected to a first handle, the plurality of the magnetic force layering units are uniformly distributed on two sides of the spindle, each magnetic force layer unit moves back and forth along a guide rail arranged along the length direction of the support through sliders, is connected with the spindle through the two joint retractable arms, drives the spindle to rotate through the first handle, and moves back and forth along the direction perpendicular to the spindle. Since each magnetic force layer unit can move back and forth along the axial directi
