Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor spindle detection technology, and in particular to a motor spindle coaxiality detection component. Background Technology
[0002] The motor spindle is an important component of a motor. As the link between the motor and the equipment for electromechanical energy conversion, it supports rotating parts, transmits torque, and determines the relative position of rotating parts with respect to the stator. In order to ensure the stability of the motor output, it is necessary to test the coaxiality of the motor spindle to prevent it from running out of control, which would accelerate the damage to the equipment.
[0003] A device for detecting the coaxiality of a motor spindle, disclosed in CN221992605U, includes a worktable with a test bracket fixed on it. The test bracket has arc-shaped grooves adapted to the end shafts of both ends of the motor spindle. A vertical plate is fixed to the upper surface of the worktable, located behind the test bracket. The vertical plate has an L-shaped structure and three horizontally movable sleeves. Each sleeve contains a vertically movable sliding rod. This device can save testing time and improve testing efficiency, making it suitable for detecting the coaxiality of large batches of motor spindles. However, existing testing devices often require disassembling bolts on the sleeves, moving the sleeves to the designated position, and then screwing the bolts back on when adjusting the position of the measuring gauge to measure spindles of different specifications. This operation is cumbersome and affects adjustment efficiency. Utility Model Content
