AI Technical Summary
During the processing of existing motor housing drilling devices, the drill rod is prone to deflection due to contact with the arc-shaped or inclined outer surface of the motor housing, which can damage the device and affect its service life.
A limiting component was designed, including a connecting sleeve, a rotating ring, a connecting block, a spiral spring, and an arc-shaped strip. Through the coordinated movement of these components, the drill rod is ensured to fit tightly against the motor housing, providing stable support and preventing the drill rod from breaking due to uneven surfaces.
This effectively prevents the drill rod from breaking when drilling on uneven surfaces of the motor housing, thus improving the efficiency and stability of the device.
