Description

Technical Field

[0001] The utility model relates to the technical field of motor assembly, and more specifically, to an assembly tool for a housing and a stator of a motor. Background Art

[0002] The servo motor is mainly composed of a housing, a stator, a rotor, an end cover and other components. The stator is installed in the housing through interference fit. Usually, the housing and the stator need to be assembled by shrink fitting. In the prior art, the stator is first placed on a press to fix it, and then the housing is placed in an oven and heated to a certain temperature (the temperature is calculated according to the design value of the interference). The worker wears heat-insulating gloves to quickly take out the housing and place it on the stator to align it. Finally, the press presses the housing down to complete the process. For example, the prior art publication number (CN110649769 B) describes an assembly tool for a servo motor casing and stator, comprising a base, a guide rod, a support ring and a guide ring, wherein the upper end of the base is symmetrically connected to the guide rod, the center of the upper end surface of the base is provided with a base boss extending upward, the upper end surface of the base is installed with a support ring, the support ring is located between the base boss and the guide rod and the height of the support ring is lower than the height of the base boss, the outer wall of the base boss is fitted with a stator, the stator comprises a cylindrical stator core and a stator winding, and the stator core is formed by circumferential splicing of evenly divided multi-petal T-shaped cores.

[0003] When the above device is in use, the base, support ring, shield, sleeve and clamp can not only firmly and reliably fix the stator, but also completely protect the stator winding of the stator, ensuring that the stator winding will not be accidentally damaged during the press-fitting process; through the arrangement of the guide ring and the insulation ring, the concentric positioning accuracy between the casing and the stator is reliable, the operation is convenient, the work efficiency is effectively improved, and the temperature of the casing will not drop rapidly, but its structure is relatively complicated, and when the insulation ring flange moves downward, the casing is easy to fall off the surface of the insulation ring flange, which affects the stability of the casing installation and the speed of assembly of the motor casing and the stator.
