Description

Technical Field

[0001] This application relates to the field of electric motor stator technology, specifically to a device for shaping the surface of an electric motor stator assembly. Background Technology

[0002] The stator of an electric motor is the stationary part of the motor, and together with the rotor, it constitutes the core component of the motor. It mainly consists of three parts: the stator core, the stator windings, and the frame. Its core function is to generate a rotating magnetic field by passing alternating current through it, providing electromagnetic force to the rotor, thereby driving the rotor to rotate and realizing the conversion of electrical energy into mechanical energy.

[0003] For example, Chinese utility model patent publication number "CN221081107U" discloses a stator assembly surface shaping device for an electric motor. This utility model involves mounting the stator assembly on a stator assembly guide turntable, then rotating the stator assembly guide turntable to the coil shaping mechanism at both ends via a Geneva mechanism. An electric slide rail drives two shaping rollers to contact the coils exposed at the upper and lower ends of the stator assembly. A rotary motor then drives the shaping rollers to rotate. With the cooperation of the stator assembly guide turntable, the shaping rollers can drive the stator assembly guide turntable and the stator assembly on its surface to rotate, thereby rolling and rounding the coils exposed at both ends of the stator assembly. Afterwards, the Geneva mechanism rotates the stator assembly to the flattening shaping mechanism, and a cylinder extends to drive the shaping pressure plate to move down, flattening the coils exposed at the upper and lower ends of the stator assembly, thus completing the shaping. It is easy to use, and can then be rotated again, making it convenient for operators to unload materials. It can achieve continuous processing and is even more convenient to use.

[0004] In the aforementioned patent, the stator assembly can automatically rotate to the coil shaping mechanism and the flattening shaping mechanism at both ends for sequential shaping. However, its rotating mechanism adopts the Geneva mechanism. After long-term use, this structure is prone to mechanical wear due to the frequent contact and friction between the active dial and the driven groove wheel, which in turn leads to positioning errors when switching workstations and affects the shaping accuracy.

[0035] Working Principle: When using this device, first place the motor stator assembly on the stator assembly guide turntable 207. Start motor 203 via the control panel.

Start cylinder 305, which pushes the sliding plate 304 to slide along the mounting plate 301, moving the connecting frame 306 so that the forming roller 309 contacts the coils at both ends of the stator assembly. Then start motor 307, which drives the rotating shaft 308 to rotate, causing the forming roller 309 to rotate and roll the coils into a round shape. After the rounding is completed, cylinder 209 is activated to reset the limit block 210. Then, motor 203 is activated to continue rotating the rotating plate 204, moving the stator assembly below the pressure plate 303. Cylinder 302 is then activated to push the pressure plate 303 downward, flattening and shaping both ends of the stator assembly. After shaping, all components are reset, and the stator assembly can be removed. The entire process does not require moving the stator assembly back and forth, making operation convenient and improving work efficiency.
