Description

Technical Field

[0001] The invention relates to the technical field of motor shaft hole processing, in particular to a motor shaft hole depth processing device. Background Art

[0002] The motor shaft is a crucial component in a motor. As the link for electromechanical energy conversion between the motor and the equipment, it supports rotating components, transmits torque, and determines the relative position of rotating components to the stator. Drilling a hole in the motor shaft is one of the steps in motor shaft processing. The center holes at both ends of the shaft serve as the reference for turning, grinding, and other processing steps, ensuring the coaxiality of the shaft's stepped surfaces and avoiding reference offset problems caused by multiple clamping. Punching holes on the side of the motor is conducive to fixing accessories: when installing transmission components such as pulleys, fan blades, gears, couplings, etc., punching holes facilitates bolt fixation to ensure the stability and reliability of the transmission system.
