Abstract

The present invention discloses an axial clearance measuring apparatus of a rotor of an automobile cooling fan motor. The apparatus includes a rack. The rack is provided with an operation platform. A lower female die is fixed on the operation platform. The lower female die is provided with a jack. A lower ejector pin is vertically installed on the rack in a sliding manner. The lower ejector pin is driven by a lower ejector pin lifting power apparatus. An upper pressing die is vertically installed on the rack in the sliding manner. The upper pressing die is provided with a through hole corresponding to a motor rotor shaft. An upper ejector pin corresponding to the rear end of the motor rotor shaft is vertically installed on the rack in the sliding manner. The upper ejector pin is in the through hole and is driven by an upper ejector pin lifting power apparatus. The rack is provided with a measuring mechanism for measuring an upper ejector pin moving distance or a lower ejector pin moving distance. The axial clearance measuring apparatus can measure an axial clearance of the rotor of the motor rapidly, a measurement result is more accurate, measurement efficiency is higher, and the apparatus can be applied to axial detection of clearances of a large scale of motor rotors.

Description

Technical field [0001] The invention relates to an axial gap measuring device, in particular to a rotor axial gap measuring device of an automobile cooling fan motor. Background technique [0002] The cooling fan of the vehicle is driven by a motor. This motor has a rotor. The rotor shaft of the rotor is supported by bearings at the front and rear ends and installed on the end covers at both ends. The end of the motor’s rotor shaft protruding from the stator shell is the front end. One end of the rotor shaft is the rear end, so the rear end of the rotor shaft is rotatably mounted on the back end cover, and the front end of the rotor shaft penetrates the front end cover and is rotatably mounted on the front end cover through the bearing, and the front end cover is clamped and fixed to the stator shell. The rotor has an armature composed of a coil with an iron core, and a segmented commutator for supplying current, and a sliding contact for power supply is provided on the commutato...
