This invention provides a special disassembly tool and method for abrasive rollers in automotive clutch steel sheet grinding equipment. The tool includes: a first fixing component mounted on the rotating shaft of the abrasive roller; a first disassembly component mounted on a first fixing nut on the rotating shaft of the abrasive roller; a second fixing component mounted on the back plate of the grinding equipment; and a second disassembly component fitted onto a second fixing nut on the rotating shaft of the abrasive roller. Both the first and second fixing components have contour holes that mate with the rotating shaft of the abrasive roller. The first fixing component manually restricts the rotation of the rotating shaft, and the second fixing component restricts the rotation of the rotating shaft by being fixed to the back plate and engaging with the contour holes. Both the first and second disassembly components have disassembly teeth, allowing the first and second fixing nuts to be disassembled by rotating the disassembly teeth. This invention solves the problems of inability to circumferentially lock the rotating shaft of the abrasive roller during disassembly and installation, and the inability of commonly used tools to achieve effective rotation in confined spaces.

The utility model discloses a composite damper based on electromagnetic-hydraulic-metal buckling coupling. The composite damper comprises a magnetic conductive rod body unit, an electromagnetic induction unit, a hydraulic damping unit and a rotary connecting unit. The magnetic conductive rod body unit penetrates through an inner cavity of the electromagnetic induction unit, and two ends of the magnetic conductive rod body unit are connected with the outside through the rotary connecting unit; the electromagnetic induction unit comprises a conductive layer in clearance fit with the magnetic conductive rod body unit and a cooling medium layer surrounding the conductive layer. The hydraulic damping unit is composed of viscous fluid filled in a cavity between the magnetic conductive rod body unit and the electromagnetic induction unit; and each magnetic conductive rod body unit comprises an energy dissipation structure capable of generating plastic deformation. Through electromagnetic induction and fluid damping composite energy consumption, a copper barrel-shaped structure is arranged, eddy current damping force is generated through the Lenz's law, mechanical energy is converted into heat energy, mechanical friction is not needed, and the maintenance cost is low; meanwhile, the hydraulic oil hinders the connecting rod from sliding through viscous resistance, and kinetic energy is further consumed.
