Description

Rotary shaft for marking machine

Technical Field

The utility model belongs to the technical field of laser marking machines, and mainly relates to a rotating shaft for a marking machine.

Background

Laser marking is the use of a laser beam to mark the surface of a variety of different substances permanently. The effect of marking is to expose deep layer substances through evaporation of surface layer substances, or to "imprint" marks through chemical-physical changes of the surface layer substances caused by light energy, or to burn out part of substances through light energy, so as to display patterns and characters to be etched.

The rotating shaft of the existing laser marking machine clamp can only be controlled in a single shaft, and marking can only be carried out on a single circumferential surface. When the marking is needed on the inclined plane of one rotating body part, the fixing screw of the rotating shaft is needed to be manually disassembled, and the rotating shaft is manually rotated for a certain angle and then locked again, so that the marking can be performed. If the surface shape of the rotating body part is changed greatly, the positions are more, a great amount of time is required for manually and frequently rotating the rotating shaft, and the accumulated position errors are also larger as the number of times of rotation is larger, on the other hand, the continuous marking of multiple inclined planes cannot be realized by a single rotating shaft.
