Sixteen-station flexible tool clamp

The sixteen-station flexible tool clamp comprises a cross-shaped rotary table column, a front connecting and positioning assembly, a rear connecting and positioning assembly and four positioning bottom plates, the front connecting and positioning assembly and the rear connecting and positioning assembly are arranged on the front end face and the rear end face of the cross-shaped rotary table column respectively, and the four positioning bottom plates are all fixedly arranged on the cross-shaped rotary table column. A front fixing boss, a front wedge-shaped expansion clamping device, a middle fixing boss, a rear wedge-shaped expansion clamping device and a rear fixing boss are sequentially arranged on the surface of each positioning bottom plate from front to back. The tool clamp is formed by assembling split structures, the structure is compact, connection is reliable, positioning is accurate, and the machining efficiency is greatly improved through sixteen clamping stations.
