FIG. 1 is a schematic diagram of a tool for disassembling a motor stator rounding tool and a stator outer hoop;
fig. 2 is an exploded view of the present tool.
Detailed Description
The tool for disassembling the motor stator rounding tool and the stator outer hoop comprises a bushing 1 and a bushing seat 2, wherein the bushing 1 is in a ring shape and the inner diameter is smaller than the outer diameter of the motor stator, a cylindrical knife edge section 11 is arranged at the edge of the inner ring of the end face of the bushing 1, the cylindrical knife edge section 11 is a straight cylindrical section and corresponds to a female die part of a die, and when the tool is used, the tool plays a role in supporting a jaw of a bench clamp, and the inner ring of the bushing 1 inwards along the cylindrical knife edge section 11 is a material returning section with a conical surface; the bushing seat 2 is in a hollow cylindrical shape, the end face of the bushing seat 2 is provided with a step 21, the bushing 1 is arranged on the step 21 of the end face of the bushing seat 2, the end faces of the bushing 1 and the bushing seat 2 are flush, the minimum diameter of the inner ring of the bushing seat 2 is larger than or equal to the maximum diameter of the bushing 1, namely the inner diameter of the stepped circle of the bushing seat is larger than or equal to the maximum diameter of the conical surface of the bushing, and the inner diameter of the other end face of the bushing seat 2 is larger than the outer diameter of the motor stator.
