The invention relates to the technical field of tool design, and discloses a pneumatic riveting instantaneous force measuring device. The measuring device comprises a special-shaped top iron, a fixedsleeve and a force measuring component, wherein a cavity penetrating through the front end surface and the back end surface is formed in the center of the fixed sleeve, the right end of the special-shaped top iron is located in the cavity and extends out of the fixed sleeve, an adjusting nut and threads extending out of the fixed sleeve are arranged at the end, extending out of the fixed sleeve, of the fixed sleeve, a compression spring is further arranged at the right end of the special-shaped top iron in a sleeved mode, and the special-shaped top iron can do reciprocating motion along the axis direction of the fixed sleeve. The device has the advantages that the structure is simple, the operation is convenient, the instantaneous stress in the pneumatic riveting process can be measured, the initial pre-pressure i
