Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of potting tools, in particular to a detachable enameled wire potting tool. Background Technique
[0002] At present, the known potting tool structure is composed of five parts: an upper end plate, a lower end plate, a bottom plate, an inner cylinder and a top plate. Sealing grooves are opened at the joint between the lower end plate and the end face of the stator core and at the contact surface between the bottom plate and the lower end plate to embed O-rings to prevent the potting adhesive from oozing out. Sealing grooves are also opened at the joint between the upper short plate and the end face of the stator core, and O-ring seals are also installed. The bottom plate of the tool is also provided with a groove for cooperating with the inner cylinder to realize the overall potting process. However, the existing potting process is difficult to demold. Since general potting adhesives have a certain bonding property, in order to separate the stator from the tool, the current method is to axially extrude or strongly pull. Even if a release agent is applied, the improvement effect is not significant, and the stator is easily damaged during the disassembly process. In addition, when the enameled wire is transferred to the teeth of the stator core, the wire will become loose, and the enameled wire is easy to fall off. At the same time, the existing tool places all the wire ends of the enameled wire on the upper end face of the stator, and the enameled wire is not formed, so that the wire ends of each phase sequence are intertwined with each other after potting, making it difficult to comb the wire sequence after potting and affecting the potting efficiency. Content of the Utility Model
