Problems solved by technology

The current laser cladding head, the adjustment of the spot diameter can only rely on the change of the distance between the laser cladding head and the cladding workpiece, but the change of the distance between the laser cladding head and the cladding workpiece will lead to the change of the powder feeding focus point, thus affecting the melting cover quality

Embodiment 1

[0020] Embodiment 1: Circular spot cladding.

[0021] The steps are as follows:

[0022] (1) Rotate the rotating shaft 10 of the integrating mirror so that the integrating mirror 8 is at a side position where the beam does not pass through;

[0023] (2) According to actual cladding needs, turn on the focusing mirror lock switch 11, and adjust the position of the focusing mirror 6 in the main body 7 of the cladding head until the optimum spot diameter is obtained. If it is necessary to obtain a cladding spot with a smaller diameter, the focusing lens 6 is placed at the upper position of the cladding head body 7; lower position;

[0024] (3) Turn off the focusing mirror lock switch 11 so that the focusing mirror 6 is fixed at a certain position inside the main body 7 of the cladding head.

Embodiment 2

[0025] Embodiment 2: Rectangular spot cladding.

[0026] The steps are as follows:

[0027] (1) Rotate the rotating shaft 10 of the integrating mirror so that the integrating mirror 8 is in the central position where the beam passes;

[0028] (2) According to actual cladding needs, turn on the locking switch 11 of the focusing mirror, and adjust the position of the focusing mirror 6 in the main body 7 of the cladding head until the optimum spot diameter is obtained; you can also turn on the locking switch 12 of the integrating mirror , adjust the position of the integrating mirror 8 in the cladding head main body 7 until the optimum spot diameter is obtained;

[0029] (3) Turn off the focusing mirror locking switch 11 (or integrating mirror locking switch 12 ), so that the focusing mirror 6 (or integrating mirror 8 ) is fixed at a certain position in the main body 7 of the cladding head.

Abstract

The invention provides a spot-adjustable laser cladding head. The laser cladding head mainly comprises a laser channel, a reflection mirror, a retroreflector and a cladding head main body, and is characterized by further comprising main components such as a focusing mirror, an integral mirror, an integral mirror fixing bracket, an integral mirror rotating shaft, a focusing mirror locking switch and an integral mirror locking switch and the like. According to the spot-adjustable laser cladding head, the position of the focusing mirror in the cladding head main body can be changed, so that the size of the cladding spot can be changed; the shape of the cladding spot can be changed by moving the integral mirror.

Description

technical field [0001] The invention relates to the field of laser cladding, in particular to a laser cladding head with adjustable light spot. Background technique [0002] During the laser cladding process, when the laser power, scanning speed and powder feeding rate are constant, as the spot diameter increases, the laser specific energy will gradually decrease, while the crack rate of the cladding layer will gradually increase, and the cracking tendency will increase. But on the other hand, as the diameter of the laser spot increases, the number of cladding passes will be reduced, the cladding energy will be homogenized, the dilution rate of the cladding layer will be reduced, the hardness of the cladding layer will be increased, and the surface quality of the cladding layer will be improved; Moreover, as the diameter of the laser spot increases, the cladding rate can also be increased. Therefore, in the laser cladding process, different optimal spot diameters should be ...
