Description

Technical Field

[0001] The utility model relates to the technical field of laser cladding heads, in particular to a high-speed laser cladding head for laser cladding. Background Technique

[0002] Laser cladding is an advanced surface modification technology. The high-energy laser beam generated by the laser cladding head melts and deposits powder or filamentous filler materials on the surface of the substrate to form one or more cladding layers, which is convenient for improving the surface performance of the substrate.

[0003] The patent specification with the publication number of CN220485835U discloses a high-speed laser cladding head for laser cladding, including a fixed table. A circular groove is opened on one side of the fixed table, a first stabilizing groove is opened at the edge of the circular groove, and an annular frame is rotatably connected inside the circular groove. This device solves the problem that the "high-speed laser cladding head" and the "rotation adjustment component" are centrally arranged at the bottom of the upgrade component, resulting in an overly complex structure, which is not conducive to the high-speed laser cladding head at the bottom to always maintain stability during the working process. Moreover, when the high-speed laser cladding head participates in the work, it should always be vertically downward. The method of controlling the high-speed laser cladding head to swing through the motor will affect the coating effect of the metal powder. In the present invention, through the cooperation of the stabilizing frame and the first fixing frame, both sides of the fixed sleeve and the coating head are restricted, and the control mechanism directly connected to the coating head is relatively simple and vertically distributed, so that the coating head can more easily maintain a vertical posture.

[0004] However, in the implementation of the related technology, it is found that the above-mentioned high-speed laser cladding head for laser cladding has the following problems: The device drives the coating head to move vertically through a servo motor, and improves the stability of the stabilizing frame during movement through the first fixing frame and the limiting plate, thereby improving the stability of the coating head during movement. During the laser cladding process, a large amount of soot is generated. When there is too much soot and the dust removal device fails to clean the soot in time, it is easy for some soot particles to adhere to the surface of the stabilizing frame. As the coating head moves up and down, the stabilizing frame moves up and down accordingly, causing the soot particles on the surface of the stabilizing frame to enter the inside of the first fixing frame, and the soot particles adhere to the inside of the first fixing frame and the surface of the limiting plate. As the device is used, the soot particles inside the first fixing frame will gradually accumulate, causing the connection between the first fixing frame and the stabilizing frame to be gradually blocked, which easily leads to difficult movement of the stabilizing frame, thereby affecting the movement of the coating head. It is easy to cause the speed of the coating head to be unstable during movement, thereby reducing the stability of the coating head during movement. In view of this, a high-speed laser cladding head for laser cladding is provided to overcome the above defects. Content of the Utility Model

[0028] During specific implementation: The fixing frame 1 is arranged inside the electric slide rail. By driving the fixing frame 1 to move through the electric slide rail, the cladding head main body 16 can be driven to move horizontally. By driving the cladding head main body 16 to move vertically up and down through the servo cylinder 15, the stability of the movement of the stabilizing rod 3 is improved by the limiting sleeve 2 and the limiting plate 4, thereby improving the stability of the vertical movement of the cladding head main body 16. When soot particles adhere to the surface of the stabilizing rod 3, when the stabilizing rod 3 moves upward, the surface of the stabilizing rod 3 is brushed by the brush 7, so that the soot particles on the surface of the stabilizing rod 3 can be brushed off, preventing the soot particles from entering the inside of the limiting sleeve 2, thereby reducing the probability of blockage at the connection between the limiting sleeve 2, the limiting plate 4 and the stabilizing rod 3. When the brush 7 has been used for a long time and has more soot particles adhering to its inside, push the two push plates 14 so that the two push plates 14 move away from each other, thereby driving the two moving rods 12 to move away from each other, causing the moving rods 12 to disengage from the positioning blocks 9. At this time, separate the positioning blocks 9 from the positioning seats 10, so that the two connecting rings 6 can be separated, so that the connecting rings 6 are disengaged from the limiting rings 5, so that the brush 7 can be removed, facilitating the replacement and cleaning of the brush 7.

[0029] As a further implementation of the above technical solution: on the sides of both connecting rings 6, a shunt pipe 17 is fixedly provided, and on the sides of both shunt pipes 17, a micro air pump 18 is fixedly provided. The shunt pipe 17 facilitates the shunting of air into a number of exhaust pipes 21.

[0030] As a further implementation of the above technical solution: on the air inlets of both micro air pumps 18, an intake pipe 19 is fixedly provided, and on the air outlets of both micro air pumps 18, an outlet pipe 20 is fixedly provided. The outlet pipe 20 facilitates the feeding of the air in the micro air pump 18 into the shunt pipe 17.

[0031] As a further implementation of the above technical solution: on the sides of both shunt pipes 17, ventilation holes are provided, and the interiors of the two ventilation holes are respectively fixedly connected to the sides of the two outlet pipes 20. The outlet pipe 20 facilitates the feeding of gas into the spray head 22.

[0032] As a further implementation of the above technical solution: on the sides of both shunt pipes 17, a number of exhaust pipes 21 are fixedly provided, and at the bottom ends of the number of exhaust pipes 21, a spray head 22 is fixedly provided. The spray head 22 facilitates the blowing of air towards the stabilizing rod 3, so that the soot particles on the surface of the stabilizing rod 3 are blown away.

[0033] During specific implementation: when the stabilizing rod 3 moves upward, the micro air pump 18 is started. The micro air pump 18 extracts the filtered air, so that the air enters the micro air pump 18 through the intake pipe 19. The micro air pump 18 feeds the air into the shunt pipe 17 through the outlet pipe 20, and shunts the air through a number of exhaust pipes 21, so that the air is sprayed onto the side of the stabilizing rod 3 through a number of spray heads 22, blowing away the soot particles on the surface of the stabilizing rod 3. Thus, the soot particles on the surface of the stabilizing rod 3 can be reduced. Then, the remaining soot particles on the stabilizing rod 3 are brushed off by the brush 7. By spraying the air onto the side of the stabilizing rod 3 simultaneously through multiple spray heads 22, the cleaning of the soot on the surface of the stabilizing rod 3 is more thorough, thereby improving the cleaning efficiency of the device for the soot particles on the surface of the stabilizing rod 3. Thus, the device facilitates the blowing away of the soot particles on the surface of the stabilizing rod 3, further improving the cleaning efficiency of the soot on the surface of the stabilizing rod 3, further reducing the probability of blockage at the connection between the stabilizing rod 3 and the limit sleeve 2, and further improving the stability of the movement of the stabilizing rod 3 and the cladding head main body 16.
