Description

Technical Field

[0001] This utility model relates to the field of laser cladding technology, and in particular to an adjustable laser cladding nozzle. Background Technology

[0002] Laser cladding, also known as laser bonding or laser coating, is a new surface modification technology. It involves adding cladding material to the surface of a substrate and using a high-energy-density laser beam to fuse it together with a thin layer on the substrate surface, thus forming a metallurgically bonded filler cladding layer on the substrate surface.

[0003] In the existing technology, laser cladding nozzles are required when performing cladding treatment on the surface of a substrate. However, most laser cladding nozzles have simple structures and poor functionality, which makes it impossible to effectively control the amount of powder ejected from the nozzle when performing cladding treatment on the substrate surface. This seriously affects the quality of laser cladding repair on the workpiece and reduces its practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problem that the above-mentioned equipment has poor practicality due to the inability to control the amount of powder ejected from the cladding nozzle during use. Therefore, an adjustable laser cladding nozzle is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable laser cladding nozzle, comprising a fixed shell, an outer shell fixedly installed at the bottom of the fixed shell, a plurality of conveying pipes provided on the inner surface wall of the outer shell, a fixed plate fixedly installed on the outer surface wall of the fixed shell, and the outer surface wall of the conveying pipes disposed inside the fixed plate, an embedding groove provided on the outer surface wall of the outer shell, an adjusting plate movably embedded on the inner surface wall of the embedding groove, and a plurality of circular grooves provided on the outer surface wall of the adjusting plate, one side of the outer surface wall of the outer shell, and the inner surface wall of the embedding groove.

[0006] Preferably, the output end of the conveying pipe is fixedly connected to a circular groove on one side of the inner wall of the embedded groove, and a motor is fixedly installed on the outer wall of the outer shell.

[0007] Preferably, the output end of the motor is fixedly fitted with a gear, and the outer wall of the gear meshes with the outer wall of the adjusting plate.

[0008] Preferably, the inner surface of the fixed shell is movably fitted with the mounting shell, and the outer surface of the mounting shell is provided with two sets of limiting grooves.

[0009] Preferably, a lens holder is movably inserted into the inner surface wall of the mounting housing, and two limiting brackets are fixedly installed on the outer surface wall of the lens holder.

[0010] Preferably, the inner surface of both limiting frames is movably inserted with limiting rods, and the limiting rods are movably inserted inside the limiting grooves.

[0011] Preferably, the inner wall of the lens holder is provided with a lens body, and two fixing brackets are fixedly installed on the outer wall of the fixing shell. Threaded rods are movably inserted into the inner walls of both fixing brackets, and arc-shaped plates are fixedly connected to the outer walls of the two threaded rods via bearings.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In use, this utility model, through the interaction of a series of components, when laser cladding repair of a workpiece is required, generates a laser beam through a laser emitting device and acts on the workpiece surface. Simultaneously, powder is ejected from a circular groove on one side of the outer wall of the outer shell through a conveying pipe and reaches the workpiece surface.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-5 As shown, this utility model provides an adjustable laser cladding nozzle, including a fixed shell 1, an outer shell 11 fixedly installed at the bottom of the fixed shell 1, a plurality of conveying pipes 12 provided on the inner surface wall of the outer shell 11, a fixed plate 13 fixedly installed on the outer surface wall of the fixed shell 1, and the outer surface wall of the conveying pipes 12 disposed inside the fixed plate 13, an embedding groove 14 is opened on the outer surface wall of the outer shell 11, an adjusting plate 15 is movably embedded in the inner surface wall of the embedding groove 14, a plurality of circular grooves 16 are opened on the outer surface wall of the adjusting plate 15, one side of the outer surface wall of the outer shell 11, and the inner surface wall of the embedding groove 14, the output end of the conveying pipes 12 is fixedly connected to the circular groove 16 on one side of the inner surface wall of the embedding groove 14, a motor 17 is fixedly installed on the outer surface wall of the outer shell 11, a gear 18 is fixedly sleeved on the output end of the motor 17, and the outer surface wall of the gear 18 is meshed with the outer surface wall of the adjusting plate 15.

[0025] The overall effect of Embodiment 1 is that when laser cladding repair of a workpiece is required, a laser beam is generated by a laser emitting device and acts on the surface of the workpiece. At the same time, powder enters the delivery pipe 12 through an external storage and pressurization device, and then is ejected from the circular groove 16 opened on one side of the outer wall of the outer shell 11 through the delivery pipe 12. It reaches the surface of the workpiece and, in conjunction with the laser, performs laser cladding repair on the surface of the workpiece. When the powder is sprayed onto the surface of the workpiece, the gear 18 can be rotated by the action of the motor 17, thereby driving the adjustment plate 15 to rotate inside the embedding groove 14. Through the rotation of the adjustment plate 15, the circular groove 16 opened on the adjustment plate 15 is no longer completely aligned with the circular groove 16 opened on one side of the outer wall of the outer shell 11 and the inner wall of the embedding groove 14. Thus, by rotating the adjustment plate 15, the amount of powder sprayed can be adjusted and controlled, improving the quality of workpiece cladding repair, avoiding powder waste, and reducing cost consumption.

[0026] Example 2: As Figures 2-5 As shown, the inner surface of the fixed shell 1 is movably fitted with the mounting shell 2. The outer surface of the mounting shell 2 is provided with two sets of limiting grooves 3. The inner surface of the mounting shell 2 is movably inserted with the lens holder 4. The outer surface of the lens holder 4 is fixedly installed with two limiting frames 5. The inner surface of each limiting frame 5 is movably inserted with a limiting rod 6, and the limiting rod 6 is movably inserted inside the limiting groove 3. The inner surface of the lens holder 4 is provided with the lens body 7. The outer surface of the fixed shell 1 is fixedly installed with two fixing frames 8. The inner surface of each fixing frame 8 is movably inserted with a threaded rod 9. The outer surface of the two threaded rods 9 is fixedly connected with an arc plate 10 through a bearing.

[0027] The overall effect of Embodiment 2 is as follows: Before laser cladding repair of the workpiece, the limiting rod 6 is first removed from the inside of the limiting groove 3 and the limiting frame 5 under the operation of the operator, so that it no longer serves to fix and limit the lens frame 4. This allows the lens frame 4 to be moved to a suitable position inside the mounting shell 2, and then fixed by the limiting rod 6. This allows for adjustment as needed, improving its practicality. Then, the threaded rod 9 inside the fixing frame 8 is rotated, causing the arc plate 10 to move outward and no longer serve to fix the mounting shell 2. This allows for adjustment of the height of the mounting shell 2, and further adjustment of the distance between the lens and the workpiece, so that the laser beam can be more focused on the workpiece, improving the quality of laser cladding repair. After long-term use, the lens inside the device is prone to severe wear. At this time, by the action of the limiting rod 6, the limiting groove 3 and the limiting frame 5, the lens frame 4 can be removed from the inside of the mounting shell 2, thereby maintaining or replacing the lens, improving the quality of laser cladding repair of the workpiece.

[0028] Working Principle: Before laser cladding repair of a workpiece, the limiting rod 6 is removed from the limiting groove 3 and the limiting frame 5 by the operator, so that it no longer serves to fix the lens frame 4. This allows the lens frame 4 to be moved to a suitable position inside the mounting shell 2 and then fixed by the limiting rod 6. Adjustment is then possible as needed. Next, the threaded rod 9 inside the fixing frame 8 is rotated, causing the arc plate 10 to move outward and no longer fix the mounting shell 2. This allows the height of the mounting shell 2 to be adjusted, enabling the laser beam to be more focused on the workpiece. During laser cladding repair, a laser beam is generated by the laser emitting device and acts on the workpiece surface. Simultaneously, powder enters the conveying pipe 12 through an external storage and pressurization device, and then exits from the outer shell via the conveying pipe 12. The powder is sprayed from the circular groove 16 on one side of the outer wall of the housing 11 and reaches the surface of the workpiece. With the cooperation of the laser, the surface of the workpiece is treated by laser cladding repair. When the powder is sprayed onto the surface of the workpiece, the gear 18 can be rotated by the motor 17, which in turn drives the adjustment plate 15 to rotate inside the embedding groove 14. By rotating the adjustment plate 15, the circular groove 16 on the adjustment plate 15 is no longer completely aligned with the circular groove 16 on the outer wall of the housing 11 and the inner wall of the embedding groove 14. This allows for adjustment and control of the amount of powder sprayed, improving the quality of the workpiece cladding repair. After long-term use, the lens inside the device is prone to severe wear. At this time, the lens holder 4 can be removed from the mounting shell 2 by the action of the limiting rod 6, the limiting groove 3 and the limiting frame 5, making it easier to maintain or replace the lens.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
