Description

Technical Field

[0001] The utility model relates to the field of laser cladding machines, in particular to a numerically controlled laser cladding machine. Background Art

[0002] CNC laser cladding machine is a device that uses laser technology for cladding processing. It controls the laser beam to scan the surface of the workpiece, causing the local area of ​​the workpiece surface to melt due to heat, and then sprays the added material onto the molten surface to form a new covering layer. This processing method can improve the hardness, wear resistance and corrosion resistance of the workpiece surface, and can also repair and reinforce damaged parts.

[0003] In order to improve the quality of metal parts and extend the service life of metal parts, it is necessary to coat the surface of metal parts with the help of a CNC laser cladding machine. For example, the prior art Chinese patent announcement number "CN114686877A" discloses a laser cladding machine for shaft parts, including a support column, the top of the support column is fixedly connected to a top slide rail, the top of the top slide rail is slidably connected to a support slide seat, the outside of the support slide seat is fixedly connected to a cantilever slide rail, the outside of the cantilever slide rail is slidably connected to a vertical slider, the outside of the vertical slider is slidably connected to a mounting slider, a laser head is arranged outside the mounting slider, and a positioning fixture is arranged outside the laser head. By fixing the target workpiece on the positioning fixture, the laser cladding processing system controls the coordinated use of the top slide rail, the support slide seat, the cantilever slide rail, the vertical slider and the mounting slider to complete the laser cladding processing of the target workpiece, and the laser cladding processing effectively guarantees the quality of the laser repair processing through the laser cladding processing. Avoid the reduction of material properties, improve the efficiency of the repair processing, improve the degree of automation and the repair accuracy, thereby improving its application range.

[0004] Some laser cladding machines use clamps to fix metal parts and cooperate with laser heads and powder feeding heads to coat metal parts. However, in actual operations, considering that the metal parts to be clad may be tubular or plate-shaped, the clamps of similar laser cladding machines can only clamp and fix metal parts of one shape. On the one hand, this reduces the adaptability of the laser cladding machine. On the other hand, replacing clamps with different clamping shapes will affect the cladding efficiency of the metal parts, resulting in reduced practicality of the device. Utility Model Content

[0022] Specifically, the laser head 6 and the powder feeding head 7 can be moved horizontally and vertically through the first slide rail 42 and the second slide rail 44 .

[0023] To go further, a first motor 45 is fixedly installed on the side of one of the rotating seats 41, and an extension rod 451 is fixedly connected to the axial end of the first motor 45, and the rotating seats 41 on adjacent sides are connected by the extension rod 451 to achieve synchronous rotation, a second motor 51 and a cylinder 9 are fixedly installed on the top of the movable plate 5, a gear 52 is fixedly installed on the axial end of the second motor 51 passing through the movable plate 5, a tooth plate 53 is fixedly installed on the side of the second slide rail 44, the gear 52 and the tooth plate 53 are meshed and rotated, and the laser head 6 and the powder feeding head 7 are fixedly connected to the axial end of the cylinder 9.

[0024] The specific operation is that a roller is rotatably connected inside the rotating seat 41, and the synchronous belt 43 is sleeved on the roller.
