A water tube bearing device of a vehicle radiator core assembling machine mainly comprises a pressing cylinder, a pressing block, a bearing cylinder, a water tube bearing block and a photoelectric sensor. By means of the pressing function of the pressing block and the supporting function of the bearing block, most of radiator water tubes in a tube bin of the assembling machine can be controlled to be arranged on the bearing device and above the bearing device, and therefore few water tubes are reserved at the bottom of the tube bin, and the technical problem that the bottommost water tube is prone to being deformed in the striking process due to too large pressure is effectively solved. When the water tubes at the bottom of the tube bin are reduced to a certain number, the photoelectric sensor arranged at the bottom sends out a signal, the water tube bearing block and the pressing block move forward and backward step by step to release a part of the water tubes to the bottom of the tube bin, and meanwhile the water tubes above the bearing block fall onto the bearing block so as to guarantee continuity of work.
