Centering and laminating device

The invention relates to the technical field of mechanical tools, aims to solve the technical problem that the fitting yield of a first product and a second product is low, and provides a centering fitting device which comprises a rack, a bearing part, a plurality of sets of centering assemblies, a centering driving mechanism and a profiling part. The bearing piece is provided with a receding opening and used for bearing a first product. The centering assembly comprises two centering pieces, the two centering pieces are arranged on the two oppositely-arranged sides of the receding opening correspondingly, the oppositely-arranged side faces of the two centering pieces are centering inclined faces, and the centering inclined faces incline in the inner diameter direction of the receding opening in the direction away from the machine frame. The centering driving mechanism is used for driving the two centering pieces of the multiple sets of centering assemblies to be close to each other on the centering plane perp
