Technical Field

The utility model relates to motor assembly, in particular to a rotor loose piece shaft-entering tool.

Background

A large number of motors are used in household appliances, when the motors are produced, the rotating shaft needs to be pressed into a center hole of a die casting in an interference fit mode, a rotor pressing shaft part consists of the die casting and the rotating shaft, a rotor sheet is provided with a ventilation heat dissipation hole and a center hole, the die casting is formed by die casting after the rotor sheet with certain stacking thickness and chute span is stacked, a chute of the die casting needs to be guaranteed, and the chute plays an important role in the performances of the motor such as rotating speed, starting torque and noise.

The traditional working mode is as follows: and a die-casting process, wherein if the rotor punching sheet is a common single punching sheet, workers sleeve the rotor sheet bulk sheets stacked to a certain thickness into the mandrel, the relative positions of the rotor sheet bulk sheets are not fixed, one end of the mandrel is larger than the diameter of a central hole of the rotor sheet, such as a hexagon head, a cylinder head or other shapes, and the other end of the mandrel is smaller than the diameter of the central hole of the rotor sheet, such as a cylinder and the tail end of the mandrel is provided with threads, the rotor sheet bulk sheets are twisted into a certain chute span by manually twisting the chute, and the rotor sheet bulk sheets twisted with the chute are screwed and fixed by nuts for die-casting. If the rotor sheet is a high-speed stamped sheet, a die-casting worker sleeves the high-speed stamped rotor lamination which is riveted into a certain thickness and has a chute span into the mandrel, and the relative position of the rotor lamination is fixed for die-casting. After the common punching sheet or the high-speed punching sheet is subjected to die casting, the nut at the end of the mandrel needs to be loosened, the mandrel and the nut are taken down, then the die casting is placed into a workpiece box, then the die casting is transferred to the next procedure, and a working field of a pressing shaft is entered for pressing the shaft of the die casting. The method comprises the following steps that all certain space distances of a die-casting and shaft-pressing working field need to be transported, a shaft-pressing die is usually a single-station shaft-pressing die, a shaft-pressing worker takes out die-casting parts and a rotating shaft from a workpiece box, the rotating shaft is sleeved into a central hole of each die-casting part, then the die-casting parts sleeved with the rotating shaft are placed into positioning holes of the shaft-pressing die, a press is started to press the rotating shaft to a specified size, the shaft-pressing die is started to reset, the rotor shaft-pressing parts are taken out after shaft pressing and placed into the workpiece box, and then the next die-casting part sleeved with the rotating shaft is placed into the workpiece box to repeat the actions. Traditional die-casting, last item production efficiency is low, because the simplex position last item during the last item, needs the handle to stretch into and press the axle die region for the maloperation easily appears in the staff, and the handle is crushed, has the potential safety hazard.

Therefore, a new solution is needed to solve this problem.
