Technical Field

[0001] The utility model relates to the technical field of laser cladding, in particular to a multi-channel coordinated laser cladding head with adjustable angles. Background Art

[0002] Laser cladding technology is a highly cost-effective surface treatment technology with the advantages of high-speed heating and cooling, low coating dilution rate, and small heat-affected zone. As the core component of laser cladding equipment, the design and performance of the laser cladding head have an important impact on the quality and efficiency of the laser cladding process. An excellent laser cladding head should have the characteristics of stable laser output, high-precision focus adjustment, reliable powder supply and gas protection system, as well as good coordination with robots or CNC systems, so as to ensure the stability, consistency and controllability of the cladding process.

[0003] At present, laser cladding heads usually use a single-channel nozzle for cladding. The single-channel nozzle cladding head is prone to uneven cladding during the laser cladding process, which affects the cladding accuracy and quality. Therefore, in engineering applications, there is an urgent need for a laser cladding head that can achieve uniform material cladding to further improve the cladding accuracy and quality.

[0006] The pipe seat is rotatably connected to one end of the powder feeding joint, and the at least two cladding nozzles are respectively connected to the pipe seat through adjustment components to adjust the angle of the cladding nozzles;

[0007] The at least two connecting pipes are both connected to the cladding nozzle, and one end of the connecting pipe away from the pipe seat is connected to the cladding nozzle for conveying powder to the cladding nozzle.

[0008] Furthermore, the cladding nozzle is L-shaped.

[0009] Furthermore, the at least two cladding nozzles are distributed on the outside of the pipe seat in a ring array.

[0010] Furthermore, the connecting pipe is a polytetrafluoroethylene metal hose.

[0011] Further, the adjustment assembly includes a mounting seat, a connecting tube and a universal ball;

[0012] The mounting seat is arranged outside the pipe seat and close to its bottom end, the connecting tube is assembled on the side of the mounting seat away from the pipe seat, and the universal ball is rotatably connected inside the connecting tube.

[0013] Furthermore, a circular connection port for the universal ball to rotate is provided inside the tube seat, and the diameter of the opening of the connection port is smaller than the diameter of the universal ball.

[0014] Furthermore, the outer side of the connecting tube is threadedly connected to a fastener whose end abuts against the universal ball.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0016] The multi-channel coordinated laser cladding head with adjustable angle increases the uniformity of coating by adding multiple cladding nozzles on the outer surface of the tube holder, and adjusts the angle of the cladding nozzle by adjusting the components to achieve cladding processing of workpieces of different shapes. The multi-cladding nozzles of the laser cladding head work together at multiple angles to effectively improve the flexibility and uniformity of the cladding process, thereby improving the cladding efficiency and quality.

[0022] Specifically, it includes a powder feeding joint 1, a pipe seat 2, at least two adjustment components 3, at least two cladding nozzles 4 and at least two connecting pipes 5; the pipe seat 2 is rotatably connected to one end of the powder feeding joint 1, and at least two cladding nozzles 4 are respectively connected to the pipe seat 2 through the adjustment components 3 to adjust the angle of the cladding nozzle 4; at least two connecting pipes 5 are connected to the cladding nozzle 4, and one end of the connecting pipe 5 away from the pipe seat 2 is connected to the cladding nozzle 4 to transport powder to the cladding nozzle 4.

[0023] In actual settings, multiple cladding nozzles 4 are added to the outer surface of the tube holder 2 to increase the uniformity of the coating. At the same time, the angle of a single cladding nozzle 4 is adjusted by adjusting the component 3 to achieve cladding treatment of workpieces of different shapes, thereby effectively improving the production efficiency during the cladding process.

[0024] It should be noted that the cladding nozzle 4 is L-shaped, at least two cladding nozzles 4 are distributed in a circular array on the outside of the pipe seat 2, and the connecting pipe 5 is a polytetrafluoroethylene metal hose.

[0028] In actual use, the angle of the cladding nozzle 4 is adjusted by rotating the cladding nozzle 4 and driving the universal ball 303 to rotate inside the connecting tube 302. The design of the universal ball 303 can achieve smooth rotation in all directions, and can achieve fine adjustment of the angle of the cladding nozzle 4, thereby improving the accuracy and flexibility of adjustment.
