Abstract

The present invention discloses a motor rotor axial clearance adjusting machine. The adjusting machine includes a rack and an operation platform. A lower female die is fixed on the operation platform. A top pressing block is vertically installed on the lower female die in a sliding manner. A lower slide seat is vertically installed on the rack in the sliding manner. A top pressing transmission piece is fixed on the lower slide seat. A lower ejector pin is vertically installed on the lower slide seat in the sliding manner. The lower ejector pin is driven by a lower ejector pin lifting power apparatus. An upper slide seat is vertically installed on the rack in the sliding manner. The upper slide seat is provided with an upper pressing die. The upper pressing die is provided with a through hole. An upper ejector pin is installed on the upper slide seat in the sliding manner. The upper ejector pin is corresponding to the rear end of a motor rotor shaft. The upper ejector pin is connected with a measuring mechanism for measuring an upper ejector pin moving distance. The clearance adjusting machine can rapidly perform axial clearance adjustment on each motor before the motor leaves the factory, thereby greatly improving clearance adjustment precision, improving efficiency, facilitating adjustment, being applicable to mass production, and ensuring product quality stability.

Description

Technical field [0001] The invention relates to a gap adjuster, in particular to a motor rotor axial gap adjuster. 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 back end, so the back 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 mounted on the front end cover through the bearing rotation, 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 commutator. The commutator is at the rear end of the rotor sh...
