    Abstract: The present disclosure provides a flexible clamping device, which is composed of a housing, a shaft I, a sleeve I, a cylinder, a connector, a shaft II, a clamping spring, a protective pad, a pressure block, a shaft III, a sleeve II and a bottom plate. The bottom plate is provided with two steps on which wheels having different sizes are fixed respectively. When the large-sized wheel is put on the bottom step, the cylinder drives the connector to move right in a plane, the protective pad on the pressure block presses the hub of the wheel, and the function of compacting the large-sized wheel is thus realized; when the small-sized wheel is put on the bottom step, the cylinder drives the connector to continuously move right in the plane, the protective pad on the pressure block presses the hub of the wheel, and the function of compacting the small-sized wheel is thus realized. The flexible clamping device in use can meet the requirement of mixed-line high precision clamping in the wheel burr brushing process, has the characteristics of ideal effect, high efficiency, safety and reliability in work and high degree of automation, and is particularly suitable for batch production on production lines.
