The invention has the technical effects that:
the invention is a universal device for the turning procedure and the welding procedure of the stator shielding sleeve, changes the original processing mode, only improves the working efficiency, reduces the risks of collision, scratch and the like caused by the previous turning procedure processing, and reduces the risks of the turning procedure clamping and transferring of the stator shielding sleeve.
1. Safer, not having adopted stator housing to rise child and turning stator housing alone, direct mount has avoided the extrusion deformation when adopting the child that rises and has transported the fish tail that collides with that the emergence.
2. The efficiency is higher, installs this device well for turning and the welding process of stator shield cover.
3. The invention changes the turning mode of the stator shielding sleeve, so that the stator shielding sleeve is directly arranged on the inner hole of the stator, the device is used for fixing the stator shielding sleeve to complete the turning process, the device is not disassembled after the turning process is completed, the welding process is switched, and the device is used for adjusting the center and welding the stator shielding sleeve in the inner hole of the stator. Therefore, the processing efficiency can be obviously improved, and the quality and the quantity can be better guaranteed.
