When the press-fitting is completed, the two second hydraulic rods can be started to jointly push the L-shaped baffle to move vertically downward and detach from the sensor housing, so that when the first hydraulic rod is continued to be started to push the push plate to move horizontally to the right, the sensor housing and the inner core bushing after the press-fitting can be pushed out of the inner cavity of the first frame and sent to the pad, thereby realizing the automatic discharge of the workpiece and reducing the labor intensity of the staff in taking the material;

[0015] 3. Through the setting of the first infrared transmitter, the first infrared receiver, the first indicator light, the second infrared transmitter, the second infrared receiver, the second indicator light and the controller, after the sensor housing is inserted into the inner cavity of the first frame, the first infrared transmitter can be started to emit infrared rays downward. When the first infrared receiver receives the signal and starts the first indicator light under the linkage action of the controller, it indicates that the right side of the sensor housing has been placed in place. Similarly, when the second indicator light is on, the surface inner core bushing is placed in place. By correcting the initial positions of the sensor housing and the inner core bushing, when the first hydraulic rod pushes the push plate for press fitting, the success rate of press fitting can be improved, thereby improving the yield rate of press fitting of the inner core bushing.
