Clamp suitable for multi-vehicle NC servo switching mechanism

The utility model relates to a fixture suitable for multi-vehicle NC servo switching mechanisms, which comprises a base, three-axis servo displacement mechanisms and positioning mechanisms, a plurality of sets of three-axis servo displacement mechanisms are arranged at preset positions on the base, and each set of three-axis servo displacement mechanism is provided with one positioning mechanism. The fixture has the advantages that the requirement for flexible switching of vehicle types during multi-vehicle-type mixed-line production can be met, the fixture generalization is high, the equipment utilization rate is increased, and the production line manufacturing cost is reduced; the production requirements of multiple vehicle types can be met by only using the occupied area of one set of equipment, so that the occupied area is reduced; when vehicle types are increased in the later period, only the position information of the new vehicle type needs to be input into an electrical program, the transformation tim
