Riveting quality detection device and method for multi-point riveting machine

The invention relates to a riveting quality detection device and method for a multi-point riveting machine. The riveting quality detection device comprises a displacement sensor, a pressure sensor anda controller, wherein the displacement sensor is used for detecting riveting displacement; the pressure sensor is arranged below riveting points and used for detecting riveting pressure; and the controller is used for drawing a corresponding relation curve of the riveting displacement and the riveting pressure and judging whether the riveting quality of the riveting points is qualified or not according to the relation between the corresponding relation curve and a standard curve tolerance zone. According to the technical scheme provided by the invention, the riveting quality detection devicedraws the corresponding relation curve of the riveting displacement and the riveting pressure for any riveting point by detecting the riveting displacement of the multi-point riveting machine and theriveting pressure at the ri
