Document Type and Number:
WIPO Patent Application WO/2023/165038
Kind Code:
A1
Abstract:
A laser cladding apparatus which has an adjustable duty ratio, the apparatus comprising a lens holder, a parabolic focusing lens, a fixed conical lens, a movable conical lens and a powder nozzle; the fixed conical lens and the parabolic focusing lens are annular structures, and reflecting surfaces of the movable conical lens and the fixed conical lens are arranged opposite to a reflecting focusing surface of the parabolic focusing lens so as to reflect, along the circumferential direction, an incident beam from the central axis direction of the parabolic focusing lens to the reflecting focusing surface, and reflect and focus the incident beam via the reflecting focusing surface; the lens holder comprises a first annular fixing part arranged on the outer periphery, a second annular fixing part arranged on the inner periphery, and a rib plate connecting the first annular fixing part and the second annular fixing part; the parabolic focusing lens is fixed on the first annular fixing part, and the fixed conical lens is fixed on the second annular fixing part; the lens holder further comprises a movement adjusting part which passes through the second annular fixing part and drives the movable conical lens to move along the central axis direction of the parabolic focusing lens, the movable conical lens is fixed at the top end of the movement adjusting part, and the powder nozzle is fixed at the bottom end of the movement adjusting part.
