Description

Technical Field

[0001] The utility model relates to a tool, in particular to a tool for adjusting the relative angle of a micro motor shaft. Background Art

[0002] At present, micro motors are mainly used in air conditioning equipment (fans, air conditioners, heaters, etc.) in shaking mechanisms, swing blade mechanisms and other mechanisms. These mechanisms are generally equipped with a transmission sleeve, and the transmission sleeve has a directional shaft hole that matches the output shaft of the micro motor. In view of the fact that the shell surface of the micro motor has connection positions such as mounting ears or mounting holes, the micro motor must be installed only when the connection position and the output shaft are aligned with the connection position and the transmission sleeve of the application equipment respectively. However, since the relative angle between the output shaft and the connection position of the micro motor is uncertain during the assembly process, the installer often needs to manually rotate the output shaft to a roughly similar angle according to the needs of the application equipment before installing it. Then the installation process may require repeated fine-tuning and modification to meet the requirements before installation can be achieved.

[0003] After the improvement, through the tooling mold, it is only necessary to align the motor output shaft with the debugging hole of the tooling, and rotate it to the specified position after matching. The relative angle between the output shaft and the motor connection position is fixed, and then it can be installed directly and accurately. Utility Model Content
