Positioning tool for new energy motor shell and using method thereof

The invention discloses a positioning tool for a new energy motor shell and a using method thereof. The positioning tool aims to overcome the defect that a positioning tool for the motor shell is poorin precision. The positioning tool comprises an inner edge positioning part and an outer edge positioning part, wherein the outer edge positioning part and the inner edge positioning part are used for positioning the outer edge and the inner edge of the motor shell respectively. By adopting an inner edge positioning mode, the positioning precision of a product is improved, the machining precisiongrade and stability of the product are improved, flexible interchange is realized for a multi-variety and few-batch production line, the production efficiency is improved, the high-strength design isadded to low-strength and high-impact positions of the tool, for machining an area with high torque and easy vibration of the product, the necessary auxiliary supporting design is added, and strong supporting force and retenti
