The invention discloses a device and method for detecting the welding quality of PINs, and particularly relates to the technical field of welding quality detection.The device comprises a working platform, a rack, a clamp, a detection assembly and a controller, and the clamp is used for fixing a to-be-detected weldment; the detection assembly comprises a detection head, sensors and a driving device, the detection head is used for pushing the PINs, the sensors comprise a force sensor and a displacement sensor, the force sensor is used for collecting the stress of the PINs, the displacement sensor is used for collecting the positions of the PINs, and the driving device is used for driving the detection assembly to move; the controller is connected with the detection assembly and used for receiving data of the detection assembly and controlling the detection assembly. And comparing the detected parameter curve with a set parameter curve, and comparing the calculated deformation Delta X of the PIN with a reference
