Flexible clamping device and dynamic clamping method for laser additive manufacturing

The invention relates to a flexible clamping device for laser additive manufacturing and a dynamic clamping method for the flexible clamping device for laser additive manufacturing. The method comprises the steps that the position and number of the clamping device are set according to the structure and size of a workpiece needing additive manufacturing; the workpiece needing laser additive manufacturing is started and placed on a base plate of a workbench, and the height of a clamping head is adjusted; the magnitude of clamping force of the clamping head is adjusted; the angle of the clampinghead is adjusted; along with increasing of the workpiece, a height adjusting mechanism drives a pneumatic clamping mechanism to increase along with the workpiece, and displacement of a piston rod is adjusted; the pneumatic clamping mechanism is adjusted to adjust the angle of the clamping head; and equipment is reset till preparation is completed. According to the structure and method, the problems that the interruption f
