Laser cladding device with an improved nozzle

摘要

A laser cladding device for applying a coating to a part comprising a laser which can generate laser light, which is adapted to heat the coating and the part, a main body defining a laser light channel adapted to transmit the laser light to the part, a coating channel adapted to transmit the coating to the part, and a vacuum channel and a nozzle having an exit. The nozzle comprises a delivery port at one end of the laser light channel, a coating port at one end of the coating channel, and a vacuum port at one end of the vacuum channel, wherein the vacuum port is positioned generally adjacent the delivery port In operation the vacuum port draws a vacuum, pulling the coating towards the part.

1. A laser cladding device for applying a coating to a part, comprising:
a laser configured to generate laser light; a main body defining: (i) a laser light channel configured to transmit the laser light to the part, (ii) a coating channel configured to transmit the coating to the part, and (iii) a vacuum channel; a nozzle attached to the main body and defining (i) a delivery port at one end of the laser light channel, (ii) a coating port at one end of the coating channel, and (iii) a vacuum port at one end of the vacuum channel, wherein the vacuum port is positioned generally adjacent the delivery port and in operation the vacuum port draws a vacuum; a zoom lens assembly configured to receive the laser light and transmit the laser light to the part, wherein the laser light heats the coating and the part in a laser work zone; and a controller configured to adjust the zoom lens assembly such that a size of the laser work zone is variable.
