Central air-conditioning wind pipe motor pre-pressure and run-out detection device

Abstract

The invention discloses a central air-conditioning air duct motor preloading and beating detection device, which includes a base, a V-shaped clamp block, a length ruler, a slide rail, a translation platform, a translation block, a rotating shaft fixture, a support rod, a drive motor, a screw and A jumping instrument, a V-shaped clamp block is fixedly installed on the base, a translation platform is slidably installed on the slide rail, a translation block is also slidably installed on the translation platform, and a rotating shaft is fixedly installed at the center of the upper surface of the translation block Fixture; a wire sleeve is threaded on the lead screw, and a run-out meter is fixedly installed under the wire sleeve; setting a length gauge can prevent the motor from being unqualified due to wrong use of the rotating shaft or reverse installation of the rotor during production; motor preloading is added to the device The detection can effectively reduce the phenomenon of motor jamming and noise caused by unqualified motor preloading; the device can also perform full detection of the end face and axial runout of the rotating shaft at the same time, reducing the situation of the fan blade running due to excessive runout of the motor shaft, etc. Improve the qualification rate of the motor.

Description

technical field [0001] The invention relates to a motor production and processing device, in particular to a central air-conditioning air duct motor preloading and beating detection device. Background technique [0002] Most of the air duct motors used in central air conditioners are double-axis motors. Due to the relatively long shaft of this type of motor, if the concentricity of the motor shaft is not controlled, the fan blades will easily swing when the motor is assembled on the central air conditioner, which will cause the noise of the whole machine. , but in the production process of the motor, since the runout of both sides of the shaft needs to be checked, the position of the motor needs to be frequently adjusted, so the efficiency of manual runout detection is low, and it is impossible to check the axial runout of the motor. When preloading, only manual pressing is used, and experience is used to judge the preloading amount. It is impossible to accurately judge whet...

[0002] Most of the air duct motors used in central air conditioners are double-axis motors. Due to the relatively long shaft of this type of motor, if the concentricity of the motor shaft is not controlled, the fan blades will easily swing when the motor is assembled on the central air conditioner, which will cause the noise of the whole machine. , but in the production process of the motor, since the runout of both sides of the shaft needs to be checked, the position of the motor needs to be frequently adjusted, so the efficiency of manual runout detection is low, and it is impossible to check the axial runout of the motor. When preloading, only manual pressing is used, and experience is used to judge the amount of preloading. It is impossible to accurately judge whether the amount of preloading is within the range. If the preloading is too small, it will easily cause the motor to be stuck and affect the quality of the motor.
