Polishing device for rotating shaft of washing machine

Abstract

The invention belongs to the field of washing machine production devices and particularly discloses a polishing device for a rotating shaft of a washing machine. The polishing device comprises a rack,a polishing motor and a polishing disk. The polishing motor is fixed to the rack. The polishing device further comprises a drive motor, a thread column, a thread piece, a rotation shaft and a fixingpart which can clamp the rotating shaft. The drive motor is fixed to the rack and drives the thread column to rotate. The thread column is rotationally connected with the rack. The end, far away fromthe drive motor, of the thread column is fixedly connected with the fixing part. The thread column is in thread fit with the thread piece. An output shaft of the polishing motor is connected with therotation shaft, the free end of the rotation shaft is connected with the polishing disk, the rotation shaft is provided with a cam, the rack is in sliding connection with a limiting piece which can limit the thread piece from rotating, the cam abuts against the limiting piece, and a spring is arranged between the limiting piece and the rack. The polishing device can polish the rotating shaft of the washing machine uniformly.

Description

technical field [0001] The invention relates to the field of washing machine production devices, in particular to a grinding device for a rotating shaft of a washing machine. Background technique [0002] Washing machines are cleaning appliances that use electric energy to generate mechanical action to wash clothes. They are divided into household and collective use according to their rated washing capacity. [0003] China stipulates that household washing machines with a washing capacity of less than 6 kg are household washing machines: household washing machines are mainly composed of a cabinet, a washing and dehydrating bucket (some washing and dehydrating buckets are separated), transmission and control systems, and some are also equipped with heating devices. Washing machines generally refer to the use of water as the main cleaning liquid, which is different from the use of special cleaning solutions and dry cleaning that are usually handled by a dedicated person.

Problems solved by technology

[0004] The rotating shaft of the washing machine is an important part to ensure the rotation of the washing machine. The surrounding wall needs to be polished before the rotating shaft is installed. The traditional grinding device is mostly polished by a hand-held grinding device. When grinding around the rotating shaft, it is impossible to ensure that the grinding of the outer wall of the rotating shaft is uniform, and the artificial hand-held grinding disc moves along the axial direction of the rotating shaft, which cannot ensure that the distance of each movement is the same, resulting in uneven grinding
