The invention relates to an adaptive regulating mechanism with a plurality of evenly stressed wire ropes. The adaptive regulating mechanism comprises an evenly stressed rope group A, an evenly stressed rope group B and a balance hammer. The rope group A and the rope group B are connected with a connecting support through a crankshaft III. The connecting support is connected with the balance hammer through a supporting seat. The rope group A includes a left wire rope I and a right wire rope II, and the wire rope I and the wire rope II are connected with the upper end of a connecting plate I through a crankshaft I. The rope group B includes a left wire rope IV and a right wire rope III, and the wire rope IV and the wire rope III are connected with the upper end of a connecting plate II through a crankshaft II. The lower end of the connecting plate I and the lower end of the connecting plate II are connected with the connecting support through a crankshaft III. The adaptive regulating mechanism is effective in adaptive regulation, the service lives of the wire ropes can be prolonged effectively, equipment safety is improved, and the adaptive regulating mechanism is an ideal structure for hammer-balanced machine tools and has fine practical application value and popularization value.
