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 adjusting machine, in particular to a motor rotor axial gap adjusting machine. 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 end and the rear end and is installed on the end covers at both ends. The end of the motor rotor shaft extending out of the stator shell is the front end, corresponding to One end of the rotor shaft is the rear end, so the rear end of the rotor shaft is rotatably mounted on the rear end cover, while the front end of the rotor shaft passes through the front end cover and is rotatably mounted on the front end cover through bearings, and the front end cover is clamped and fixed with the stator housing. The rotor has an armature consisting of a coil with an iron core and, for the supply of electric current, a segmented commutator on which sliding contacts are arranged for the p...
