AI Technical Summary
Existing laser cladding lenses lack effective protective structures when processing deep holes, making it difficult to control the distance between the lens and the workpiece hole wall, and easily causing collision damage.
A laser cladding lens with an ultra-fine inner hole was designed. It adopts an end protection component and a protective component. The screw rod driven by a micro servo motor is adjusted to ensure the stability of the distance between the light output powder feeding connector and the workpiece hole wall. The anti-collision cap and spring are used to buffer the collision force and prevent lens wear.
This effectively prevents the lens from colliding and wearing when it penetrates deep into the inner hole of the workpiece, thus improving the stability of the processing and the service life of the lens.
