Description

Technical Field

[0001] The utility model relates to the technical field of roller processing, in particular to a feeding device for roller processing. Background Art

[0002] To put it simply, a roller is an axis structure that can be used for rolling. The axis can be rolled by connecting it to a driving device, such as the rotating shaft of a motor.

[0003] Roller processing in Chinese means processing rollers, which usually refers to the process of manufacturing and modifying rollers through machining, heat treatment, surface treatment, etc. Rollers are a common mechanical part, widely used in various transmission systems, conveying equipment and other fields.

[0004] Shaft surface drilling refers to machining one or more holes on the surface of the shaft, usually for the purpose of installing and fixing other components, increasing lubrication or reducing weight.

[0005] Holes can be made by drilling, boring, milling, etc. Depending on the needs, the shape and size of the hole will also be different, such as round, square, rectangular, etc. When drilling holes on the shaft surface, the position, size, depth and other parameters of the hole need to be determined according to the actual application and design requirements.

[0006] Shaft surface grinding refers to the treatment of the shaft surface by using abrasive tools such as sandpaper, grinding wheels, and polishing wheels to improve surface quality, reduce surface roughness, eliminate stress, and improve corrosion resistance. Shaft surface grinding is usually divided into several stages: rough grinding, semi-finishing grinding, and fine grinding.

Due to the different diameters and lengths of the shaft, during processing, in order to ensure that the processing area of ​​the shaft can contact the drilling head of the drilling machine or the grinding head of the polishing grinder, it is necessary to ensure that the up and down movement adjustment of the shaft is stable, that is, it is also necessary to design a structure that can facilitate loading to facilitate the processing of the roller.
