[0002] At present, whether the installation of the motor rotor bearing is qualified or not, the following method is usually used: drive the motor to run, listen to the sound of the motor rotor bearing rotation, if the sound is smooth, it is judged that the pre-installation of the motor rotor bearing is qualified; otherwise it is judged as unqualified; this detection method cannot Accurately measure the axial clearance between the motor rotor output shaft and the motor rotor bearing. Sometimes the motor rotor bearing rotates smoothly, but in fact the axial clearance between the motor rotor output shaft and the motor rotor bearing is too small or too large. Large, affecting service life

The invention discloses a motor rotor bearing preassembly detection device. The device comprises a support table; a motor positioning jig and a support frame are arranged on the support table; a sliderail is vertically arranged on one side face of the support frame; a sliding support seat which can move up and down along the slide rail is arranged on the sliding rail; a first air cylinder is vertically arranged on the sliding support seat, the piston rod head of the first air cylinder is also vertically arranged and is connected with a prepressing head; a disc is arranged at the upper regionof the prepressing head; a displacement sensor is arranged on the disc; and one end of the displacement sensor is arranged on the disc, and the other end is arranged on the sliding support seat. According to the motor rotor bearing preassembly detection device, a motor rotor output shaft can be pressed by the prepressing head when the sliding support seat moves downwards, a second air cylinder stops working at the moment, the first air cylinder extends out of a piston rod to drive the prepressing head to press the motor rotor output shaft down, thereby enabling the displacement sensor to measure the axial displacement of the motor rotor output shaft, and the device is simple in structure and high in detection precision.
Description
technical field [0001] The invention relates to a motor rotor bearing pre-installation detection device which can reduce the working intensity, improve the detection efficiency and reduce the detection cost. Background technique [0002] At present, whether the installation of the motor rotor bearing is qualified or not, the following method is usually used: drive the motor to run, listen to the sound of the motor rotor bearing rotation, if the sound is smooth, it is judged that the pre-installation of the motor rotor bearing is qualified; otherwise it is judged as unqualified; this detection method cannot Accurately measure the axial clearance between the motor rotor output shaft and the motor rotor bearing. Sometimes the motor rotor bearing rotates smoothly, but in fact the axial clearance between the motor rotor output shaft and the motor rotor bearing is too small or too large. Large, affect the service life. [0003] For this reason, we have developed a motor rotor bea...
