The invention relates to press fitting equipment and a press fitting mechanism. The press fitting mechanism comprises a press fitting assembly, a displacement sensor, a pressure sensor and a guide assembly. The press fitting assembly comprises a pressing head, the pressing head comprises a first end and a second end, the displacement sensor comprises a main body and a pull rod, the main body is fixed to the first end, and the pull rod penetrates in the main body in a sliding mode. The pressure sensor is arranged at the first end. The guide assembly comprises a guide sleeve and a pressing block. A guide hole is formed in the guide sleeve in the axial direction. The second end penetrates in the guide hole in a sliding mode. The pressing block is arranged on the outer peripheral edge of the guide sleeve. One end of the pull rod abuts against the pressing block. The press fitting equipment comprises a machine frame, the press fitting mechanism and a hydraulic cylinder. The guide assembly of the press fitting mechanism is fixed to the machine frame. The hydraulic cylinder is arranged on the machine frame and provided with a telescopic rod. The telescopic rod pushes the pressing head to move. The displacement sensor can accurately detect the press-fitting depth, force detected by the pressure sensor is press fitting force, and the press fitting mechanism is high in press fitting precision and simple in structure.
