ABSTRACT: Based on an analysis of clamping methods for the automatic assembly of small solid rockets, clamping force calculation, simulation, and experimental verification were carried out for different clamping solutions. The results show that when using a three-jaw chuck fitted with a 0.5 mm thick graphite rubber pad between the chuck jaws and the rocket shell, a clamping pressure of 0.5 MPa can prevent slippage even under the maximum torque load of 390 N∙m. The resulting deformation has no adverse impact on product quality and assembly performance. Considering the profile characteristics of the clamping surface of small solid rockets and economic efficiency, a universal clamping tooling was designed. This work lays a foundation for the automatic assembly of small solid rockets.
