Abstract

The invention provides a laser-shock-based device for deformation connection of metal sheets and a method thereof. The device is composed of a laser emission system, a control system and a deformation connecting system. The laser emission system is composed of a pulsed laser device, a mirror, an adjustable focusing lens, a lens support and a base. The control system is composed of a laser controller, a computer, a hydraulic control system and a three-dimensional moving platform controller. The deformation connecting system is composed of an edge pressing device, a workpiece system, a combined female die, an automatic die opening and closing device and a three-dimensional moving platform. According to the laser-shock-based device, pulsed lasers are used as an energy source, deformation connection of two or more layers of the same or dissimilar metal sheets is achieved through the combined female die, the clamping-connection degree between the metal sheets is improved, and the connection strength is improved. The female die is automatically opened and closed through the automatic die opening and closing device, so that the work efficiency is improved; when the female die is closed, the laser-shock-based device has a self-locking function, so that the precision of deformation connection is guaranteed.
