Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary devices, in particular to a roller coating auxiliary device. Background Art

[0002] Hobs are gear processing tools with teeth arranged in a spiral line along a cylinder or cone. They are used to process cylindrical gears, worm gears and other cylindrical toothed workpieces by the development method. During the production and processing of hobs, a layer of transition metal compounds with wear resistance, corrosion resistance and good bonding strength needs to be plated on the surface of the hobs to reduce the wear of the tools during the cutting process, improve the service life of the tools and the surface quality of the processed parts. During the coating process of the hobs, auxiliary devices are needed to clamp the hobs so that the hobs can be stably coated.

[0003] For example, the authorized patent with announcement number CN 206607311 U (a cylindrical shank tool coating fixture device in a vacuum coating machine) includes a tool fixing sleeve, a pinion, a large gear and a bottom tray.

The pinion is installed on the positioning pin of the bottom tray and meshes with the large gear. The pinion is installed on the self-rotating rod of the coating machine rotating frame through the bottom tray.
