Description

Numerical control machining device for surface highlight chamfering of watchcase Technical Field The utility model relates to the technical field of watchcase processing, in particular to a numerical control processing device for a highlight chamfer of a watchcase surface. Background Watchcase processing refers to a process of precisely machining a shell (usually metal, ceramic or composite material) of a product such as a clock, intelligent wearing equipment and the like, and comprises the procedures of cutting, milling, drilling, chamfering, polishing and the like so as to achieve the dimensional accuracy, surface finish and assembly suitability required by design. The prior patent (bulletin number: CN 220783447U) discloses a watch case polishing machine, and relates to the technical field of watch case polishing. This watch case polishing machine, including the bottom plate, through the surface mounting of bottom plate has two fixed plates, the side fixed mounting of bottom plate has first connecting plate, make the staff place the watch case on the surface of second gasket, then rotate the knob and make the lead screw rotate and promote a fixed plate, make the watch case fixed, fix through the staff is manual, make the fixed more firm of watch case, and can not cause the damage to the watch case, through starting first motor, drive second gear through first motor and make first gear and third gear prolong to the rack and remove, then start the second motor, make the second motor drive polishing piece polish the watch case, make the polishing piece can carry out the omnidirectional polishing to the watch case, polishing area is bigger more thorough, the labour has been saved. The polishing piece can polish the watch case in an omnibearing way in the using process of the polishing machine, the polishing area is larger and more thorough, and the labor force is saved, however, the polishing work can be sequentially carried out on the front side and the back side of the watch case only when the watch case is polished due to the fact that the fixing plate and the bottom plate slide on each other, and in the process, the watch case needs to be fixed for many times, and the whole process is complex.
