Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 2 to 5, the present invention provides a technical solution: a polishing device for MIG welding color belts of rear flanges of inner cylinders of washing machines comprises a polishing mechanism and a polishing platform 1.
Grinding machanism includes arm 2 and first motor 3, and arm 2 adopts the HX series product of modern heavy industry production, and first motor 3 is installed on arm 2, and first motor 3's output shaft sets up polishing piece 4.
The polishing platform 1 is provided with a rotary clamping mechanism, the rotary clamping mechanism comprises an oil cylinder 5, a second motor 6 and a chuck 7, the second motor 6 is fixedly connected with the polishing platform 1, an output shaft of the second motor 6 is provided with a first gear, the chuck 7 is rotatably connected with the polishing platform 1 through a rotary support 8, and the lower end of the chuck 7 is provided with a second gear meshed with the first gear.
The chuck 7 comprises a chuck body 71 and jaws, a through hole is formed in the center of the chuck body 71 and is in sliding connection with a driving ring 72, three inclined first sliding grooves are uniformly distributed in the periphery of the driving ring 72 (inclined towards the axis direction of the driving ring), and three second sliding grooves extending in the horizontal direction are uniformly distributed in the circumferential direction of the upper end face of the chuck body 71.
