The invention is described in further detail below with reference to the attached drawings and embodiments:
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.
Preferably, a convex ring 22 is circumferentially arranged on the inner ring of the bushing seat 2 near the other end face of the bushing 1, and three semicircular through grooves 23 are uniformly distributed on the surface of the convex ring 22 along the axial direction at intervals. The convex ring and the semicircular through groove are arranged so as to facilitate the bushing to be taken out when the bushing is replaced, and the bushing can be detached from the step on the end face of the bushing seat only by pushing the toothed sleeve through the semicircular through groove by adopting the rod piece.
The using method of the tool is as follows:
1. when the squirrel cage or the hoop breaks away from the motor stator assembly, the lining seat of the tool is vertically arranged on a stable tabletop, one surface without the lining faces upwards, the motor stator assembly welded by laser and the bottom surface of the round splicing tool are arranged on the lining seat of the tool, and after a certain force is applied to the motor stator assembly and the end surface of the round splicing tool by adopting an ejector rod, the clasping force of the motor stator to the round splicing tool mandrel is far greater than the clasping force of the squirrel cage or the hoop to the motor stator, so that the squirrel cage or the hoop breaks away from the motor stator assembly firstly.
2. The lining seat of the tool is vertically placed on a stable tabletop again, one surface with the lining faces upwards, the motor stator assembly after the squirrel cage or the hoop is removed through the previous procedure and the mandrel part of the round splicing tool are placed on the lining of the tool, after a certain force is applied to the motor stator assembly and the ejector rod on the end face of the mandrel part, the mandrel of the round splicing tool can be separated from the motor stator assembly, and therefore the squirrel cage or the hoop and the round splicing tool are removed from the motor stator assembly.
The tool optimizes the manufacturing process of motor stator parts, provides a reference thought for equipment manufacture during mass production of motor products, reduces the research and development cost of the equipment and improves the quality of the motor products. After the stator assembly is subjected to laser welding, the stator assembly round-splicing tool and the squirrel cage or anchor ear can be simply taken out from the motor stator assembly. The assembly working efficiency of the motor stator assembly is improved, and the assembly quality of the motor stator assembly is ensured.
