The invention discloses a flexible clamp switching system. The flexible clamp switching system is used for the clamp switching field. The system comprises a sliding table, a trolley moving mechanism,and multiple clamp warehouses; the sliding table is provided with a first linear guide rail, the trolley moving mechanism can transport clamps along the first linear guide rail, the clamp warehouses are distributed on one side or two sides of the sliding table, and the clamp warehouses can carry clamp switching with the trolley moving mechanism. Each clamp warehouse corresponds to a tool clamp ofone vehicle type, the manner that multiple vehicle types use the independent tool clamps is adopted, the mechanical structure is simplified, and the mounting and maintaining difficulty is reduced; theclamp warehouses are arranged on one side or two sides of the sliding table, the tool clamps of multiple vehicle types can be stored in an online manner, clamp switching is achieved through the sliding table and the trolley moving mechanism, and rapid switching of production of multiple vehicle types can be achieved. According to the system, in the planning stage, a guide-in space of a new vehicle type is reserved, when the new vehicle type is guided in on the later period, only a new clamp warehouse needs to be directly guided in, the transformation construction period is greatly shortened,and the cost is greatly reduced.
