Description

Technical Field

[0001] This application relates to the field of stator processing, and more particularly, to a stator shaping and rounding device. Background Art

[0002] An electric motor generally includes two parts: a stator and a rotor. Taking an AC motor as an example, the rotor is placed inside the stator. By passing alternating current through the stator, an alternating magnetic field is generated to drive the rotor to rotate. Traditional stators are of two types: squirrel-cage type and wound-rotor type. Now, due to the high degree of automation in production, the structural form of the stator has also changed greatly. There is a new type of combined stator, which disassembles the stator into individual stator blocks. Each stator block is independently wound as an excitation winding, and then several stator blocks are fitted into a circle and nested inside an annular forming hoop, thus assembling the stator of the electric motor.

[0003] Currently, when processing such a stator, first use a winding machine to wind each stator block, then workers manually fit the stator blocks into a circle, and then fetch a matching forming hoop and use a machine to forcibly press the forming hoop downward onto the circle formed by the fitted stator blocks, so as to tightly fit the stator blocks inside the forming hoop. In the prior art, the rounding efficiency of the stator is low when rounding, and the rounding effect is not good. Summary of the Utility Model

At the same time, the fourth cylinder 310 is driven to lower the pressing head 311 to the upper end of the pre-formed circular stator and abut against the top of the pre-formed circular stator to fix the pre-formed circular stator. Then, the pre-formed circular stator is welded by the welding gun 408 to complete the stator circular forming operation. Finally, the formed circular stator is clamped by another machine gripper 307 and sent to the next process.
