the weight of the first positioning piece 5 and the second positioning piece 6 is reduced, so that the force applied to the bidirectional screw rod 3 and the first guide rod 4 when the shaft is inserted into the inner ring of the bearing body 23 is reduced.
In summary, after the bearing body 23 is clamped and positioned by the relative movement of the first positioning piece 5 and the second positioning piece 6, the inner ring of the bearing body 23 is heated by the heating wire 20, and after the heating, the shaft is directly inserted into the inner ring of the bearing body 23 by the existing equipment;
compared with the heating of the bearing body 23 by a traditional heating furnace, the shaft can be inserted immediately after the inner ring of the bearing body 23 is heated to the specified temperature, the heating furnace needs to take out the bearing body 23 from the furnace, and the bearing body 23 is cooled to a certain degree in the process, so that the insertion of the shaft is influenced to a certain degree;
