High-precision clamp and high-precision clamping device

The invention discloses a high-precision clamping device. The device comprises a pedestal and a high-precision clamp arranged on the pedestal. The high-precision clamp comprises a base. A clamping mechanism used for clamping materials is arranged on the base, a pushing mechanism and a distance measuring mechanism are arranged on one side of the clamping mechanism, the pushing mechanism is used forpushing out the materials in the clamping mechanism, and the distance measuring mechanism is used for measuring the depth of the materials inserted into the clamping mechanism. With the clamping mechanism, the clamp can adapt to materials with different outer diameters, and the requirement for flexible production is met; with the pushing mechanism, the clamping mechanism can adapt to materials with different heights when be used for clamping the materials, the requirement for flexible production is met; meanwhile, the clamping mechanism can stably and accurately get away to release the materials, and the assembling p
