[0002] When the motor rotor and the rotor shaft are assembled into the shaft, due to the interference fit between the rotor shaft and the motor rotor, a large force is required to make the motor rotor fit into the shaft. In the prior art, the motor rotor and the rotor shaft are The rotor shaft is pressed into the motor rotor by a press-fitting machine. This type of shaft installation is likely to cause the rotor to be skewed and shifted, so that the verticality and concentricity between the motor rotor and the rotor shaft cannot be guaranteed.

The invention discloses an efficient and automatic rotor-into-shaft tool which comprises a bottom plate, a base plate, a locating seat and a locating sleeve. The bottom plate, the base plate, the locating seat and the locating sleeve are sequentially arranged from bottom to top, and a pressing sleeve is arranged above the locating sleeve. A through hole is formed in the center of the base plate. A locating hole corresponding to the through hole is formed in the center of the locating seat, and the top of the locating seat extends upwards to form a plurality of first rotor limiting claws equally spaced and isometrically distributed. The locating seat is sleeved with the locating sleeve, the locating sleeve can elastically do vertical reciprocating motion along the locating seat, the top of the locating sleeve extends upwards to form a plurality of second rotor limiting claws which are higher than the first rotor limiting claws and are equally spaced and isometrically distributed, and the positions of the first rotor limiting claws correspond to the positions of the second rotor limiting claws. The central line of the pressing sleeve, the central line of the locating hole and the central line of the through hole coincide. According to the efficient and automatic rotor-into-shaft tool, when a rotor is assembled into a shaft, the structure is simple, cost is low, the rotor can be prevented from shifting, the angle bisection consistency is guaranteed, and therefore the perpendicularity and concentricity of the rotor and the rotor shaft can be guaranteed.
Description
technical field [0001] The invention relates to a motor rotor shaft-entry tooling, in particular to an efficient and automatic rotor shaft-entry tooling. Background technique [0002] When the motor rotor and the rotor shaft are assembled into the shaft, due to the interference fit between the rotor shaft and the motor rotor, a large force is required to make the motor rotor fit into the shaft. In the prior art, the motor rotor and the rotor shaft are The rotor shaft is pressed into the motor rotor by a press-fitting machine. This shaft-in installation method is likely to cause the rotor to skew and shift, so that the verticality and concentricity between the motor rotor and the rotor shaft cannot be guaranteed. Contents of the invention [0003] The purpose of the present invention is to provide a high-efficiency and automatic rotor shaft entry tooling, which has a simple structure and low cost, and can prevent the rotor from shifting when the rotor enters the shaft, and ...
