Convenient-to-fix auxiliary device for motor rotor processing

Abstract

The invention discloses a convenient-to-fix auxiliary device structure for motor rotor processing. The convenient-to-fix auxiliary device comprises a semi-closed box, wherein a two-way threaded rod ishorizontally arranged inside the semi-closed box; the two-way threaded rod is located at the middle line of a longitudinal side wall of the semi-closed box; a connecting rod is horizontally welded atone end of the two-way threaded rod; the other end of the two-way threaded rod is rotationally connected with an inner side wall of the semi-closed box through a bearing; and the two-way threaded rodis sleeved with two thread bushings. Firstly, double fixing assemblies are arranged in the device, so that a good fixing effect is achieved, and a rotor can be supported. Secondly, the distance between two clamping plates can be adjusted manually, which is suitable for fixing rotors of different sizes, thereby achieving high variability. Finally, the assemblies used for adjusting the distance between the clamping plates are isolated, so that the situation that the assemblies cannot be used normally when debris generated during drilling enters the assemblies is avoided.

Description

technical field [0001] The invention relates to the technical field of motor rotor processing, in particular to a conveniently fixed motor rotor processing auxiliary device. Background technique [0002] Rotor is a technical term that refers to a rotating body supported by a bearing, such as an object without a rotating shaft itself, such as a disc. When it adopts a rigid connection or an additional shaft, it can be regarded as a rotor. According to the ISO standard, the rotating body supported by a bearing The body is called the rotor, and the rotor is mostly the main rotating part in power machinery and working machinery. When the rotor rotates at a certain speed, it will deform greatly and cause resonance. The speed at which resonance is caused is called the critical speed of the rotor. , The motor rotor processing is one of the main processes of the motor, especially the end face of the motor rotor is one of the main processes of the motor rotor calibration and balance. ...

AI Technical Summary

Problems solved by technology

[0003] Due to the simple structure of the existing fixing components when the rotor is drilled, the rotor cannot be effectively fixed, and the drilling tool will exert pressure on the rotor. The rotor does not have a strong support, and the processing surface will topple over, resulting in the deviation of the aperture. If the hole is processed to a large size Not uniform, the quality of the inner hole is unqualified, which directly affects the appearance grade of the motor rotor and the life of the motor, and there are many types of motors, the existing fixing components cannot be applied to different sizes of rotors, when it is necessary to drill holes for different sizes of rotors When drilling, it is necessary to replace the fixed components, the steps are cumbersome, the variability is poor, and a lot of waste will be generated during drilling. If the waste is stuck on important components, it will affect the use effect
