The invention discloses a cylinder head duct press-fitting method, system and device with self-adaptive characteristics. The press-fitting method includes the following steps: obtaining the air pressure signal sprayed between the bottom surface of the press-fitting head and the cylinder head press-fitting step surface; according to the obtained air pressure signal to obtain the real-time distance from the bottom surface of the press-fit head to the press-fit step surface of the cylinder head; according to the obtained real-time distance, obtain the press-fit depth value of the conduit to be pressed into the conduit hole of the cylinder head, and judge the numerical range of the press-fit depth value ; When it is detected that the press-fit depth value does not reach the preset value range, the control drives the press-fit head to move down until the press-fit depth value reaches the preset value range. The cylinder head conduit press-fitting method with self-adaptive characteristics provided by the present invention controls and drives the press-fitting head to adjust adaptively until the press-fit depth value reaches a preset value range, avoiding the occurrence of bad press-fitting phenomena; improving the efficiency of cylinder head press-fit conduit Increase production efficiency and reduce waste rate.
