Heavy hammer type bearing pulling device

The utility model relates to a heavy hammer type bearing pulling device. One end of a screw rod is welded with a handle and a punching pad, and a punching hammer sleeves behind the punching pad, and the middle part is rotationally connected with a connecting lever; the other end is rotationally connected with an expanding head; both ends of the connecting lever are connected with positive and opposite face pulling rods through a pin shaft, and positive and opposite face pulling rod heads are provided with overturned positive and opposite hooking heads. When the heavy hammer type bearing pulling device is in use, inner oblique faces of the positive and opposite face pulling rods are tightly bonded to expanding heads, and bearing inner races are inserted, and the handle is rotated in anticlockwise direction; under the effect of the expanding head, the positive and opposite face pulling rods are expanded, and the positive and opposite face pulling rod heads are overturned, and the positive and opposite hooking heads are buckled on the bearing inner races; the heavy hammer is glided reversely towards the punching pad by manual force, so as to further impact the punching pad; the punching pad drives the screw, the connecting levers rotationally screwed to the screw rod, the pin shaft, and the positive and opposite face pulling rod heads to move outwards; the positive and opposite hooking heads hook the bearing inner races so that the bearings are moved outwards, and then the bearings are pulled out. The heavy hammer type bearing pulling device is simple in structure, convenient to operate, labor-saving, and capable of rapidly pulling out various bearings and not damaging them.
