Abstract
Description
Technical Field
[0001] The invention relates to the technical field of motor manufacturing, and in particular to a gyro motor stator installation line limiting method and a pressing tool. Background Art
[0002] The fault phenomenon of the existing gyro motor is that the impedance of the A / B phase of the 2-channel gyro is infinite, and the product is reset to zero. In the process of finding the cause of the reset, the gyro is disassembled layer by layer. When it is disassembled to the gyro motor stator, it is found that the A / B phase installation wires of the two gyro motors interfere with the bottom surface of the end cover bearing, the insulation layer of the installation wire has been damaged and the core wire is exposed, and the end cover bearing is in contact with the exposed point of the core wire, causing a short circuit, which leads to the insulation performance of the gyro motor being unqualified. The fault phenomenon is transmitted to the outside through the inflation nozzle of the float assembly. When it is transmitted to the conductive hairspring of the wire guard assembly, the corresponding conductive hairspring is instantly melted due to excessive current, causing the gyro to fail. After analysis, it was found that the insulation layer of the stator installation wire is wrapped with polytetrafluoroethylene material, and the characteristic of polytetrafluoroethylene itself is that it is easy to debond. The existing process method only requires a small amount of glue on the bottom surface of the installation wire, which cannot meet the sealing requirements. Instead, in the subsequent operation process, the installation wire may be separated from the original glue layer by the force of the assembly link and rebound to contact the bottom surface of the end cover bearing. Under high-speed operation, the insulation layer at the contact point will be worn out quickly, resulting in an internal short circuit fault. It is urgent to study a reliable installation wire limit sealing method. Summary of the invention

[0048] Dip the room temperature epoxy glue and dispense glue from the top plane of the installation line as the attachment point. The total amount of glue used should refer to a ball with a diameter of about 2mm.
