Description

Technical Field

[0001] This utility model relates to the field of laser cladding device technology, and in particular to a laser cladding head anti-splash mechanism. Background Technology

[0002] Laser cladding, also known as laser bonding or laser coating, is a novel surface modification technology. It involves adding a cladding material to the substrate surface and using a high-energy-density laser beam to fuse it together with a thin layer on the substrate surface, forming a metallurgically bonded cladding layer. Laser cladding is characterized by low dilution but strong adhesion, exhibiting a metallurgical bond with the substrate. It can significantly improve the wear resistance, corrosion resistance, heat resistance, oxidation resistance, or electrical properties of the substrate material surface, thereby achieving surface modification or repair. It meets specific performance requirements of the material surface while saving significant material costs. However, during laser cladding, splattering can easily occur when the laser head is positioned directly on the object.

[0003] Chinese Patent Publication No. CN220317957U discloses an anti-splash laser cladding inner nozzle, comprising a laser head and a nozzle. The nozzle is fixedly installed at the bottom of the laser head, and a protective gas tube assembly is installed through the outer surface of the laser head. Simultaneously, a powder feeding side head assembly is fixedly installed on the outer surface of the nozzle. A mounting platform is fitted on the outer surface of the laser head, and an anti-splash mechanism is provided on the outer surface of the nozzle near the bottom of the powder feeding side head assembly. The anti-splash mechanism includes a conical protective cover fitted on the outer surface of the nozzle, and the conical protective cover and the mounting platform are fixedly connected by a fixture. The anti-splash mechanism enables the entire nozzle to have a protective and isolated structure. The conical protective cover can isolate the molten pool during the laser cladding process, preventing splashing inside the molten pool from causing safety accidents and improving operational safety.

[0004] The existing anti-splatter mechanism for laser cladding heads is installed at the laser cladding head position, making it difficult for external users to observe the interior during the laser cladding process, thus affecting the process. In addition, this laser cladding shielding mechanism is also easily limited by the structure of the irregularly shaped object being clad, resulting in the inability to effectively and completely shield it. To address this, we propose an anti-splatter mechanism for laser cladding heads. Utility Model Content

[0005] One object of this invention is to solve at least the problems described above and to provide at least the advantages that will be explained later.

[0006] Another objective of this invention is to provide a splash-proof mechanism for laser cladding heads, which prevents splashing at the laser cladding head without affecting user observation, and this splash-proof mechanism is more adaptable to objects of different shapes that are laser clad.

[0007] To achieve the above objectives and some other objectives, the present invention adopts the following technical solution:

[0008] A laser cladding head anti-splatter mechanism includes: a laser cladding platform, an anti-splatter placement groove, a limiting component, an anti-splatter shielding component, a pushing component, and a laser cladding component. The laser cladding platform has an anti-splatter placement groove on its outer wall. Limiting components for limiting object displacement are installed on both sides inside the anti-splatter placement groove. Anti-splatter shielding components are installed on both sides above the anti-splatter placement groove. A pushing component for pushing the object out of the groove is installed at one end of the anti-splatter placement groove. The laser cladding component is installed on one side of the anti-splatter placement groove.

[0009] Preferably, the anti-splash placement slot has multiple horizontally spaced assembly slots on both sides, and a protective baffle is installed on the outer wall of the assembly slot.

[0010] Preferably, a first electric telescopic rod is installed inside the assembly slot, and the telescopic end of the first electric telescopic rod extends into the anti-splash placement slot through a through hole in the protective baffle. A limit plate is installed at the end of the telescopic end of the first electric telescopic rod.

[0011] Preferably, the splash shielding assembly includes a rotating shaft installed at both ends of the splash shield placement slot, an assembly frame installed on the outer wall of the rotating shaft, a splash shield installed between the assembly frames, a bracket installed at one end of the rotating shaft, a rotating handle installed on the outer wall of the bracket, and one end of the rotating handle connected to the rotating shaft.

[0012] Preferably, the other end of the anti-splash placement trough is provided with a discharge port, the pushing component includes a mounting base, a second electric telescopic rod is installed on the outer wall of the mounting base, and a pushing plate is installed on the telescopic end of the second electric telescopic rod.

[0013] Preferably, the laser cladding assembly includes a laser cladding head, a third lead screw module is mounted above the laser cladding head, a second lead screw module is mounted at one end of the third lead screw module, and a first lead screw module is mounted below the second lead screw module.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. Compared with existing devices, this laser cladding head anti-spatter mechanism places the object to be laser clad in an anti-spatter placement slot. The slot has a depth relative to the laser cladding platform, which limits the amount of spatter generated during the laser cladding process, making it difficult for spatter to splash from the slot onto the platform and adversely affect other components. Furthermore, anti-spatter shielding components are installed on both sides above the anti-spatter placement slot. These components further protect the space above the slot, ensuring that even if spatter falls outside the slot, it is still blocked by this structure, effectively improving the anti-spatter effect of the laser cladding head. The anti-spatter shields can be rotated by a handle, and through the connection of the mounting bracket, the anti-spatter shields can change their position as they rotate. The distance between the two anti-spatter shields can be further reduced as needed to improve the anti-spatter shielding effect. This structure can perform anti-spatter operations on objects of different shapes, providing a more comprehensive overall anti-spatter effect, effectively protecting equipment and components on the platform, and facilitating user observation with less restricted field of vision.

[0016] 2. Compared with existing devices, the anti-splatter mechanism of this laser cladding head has a horizontally spaced assembly slot in the anti-splatter placement slot, which is used to install multiple sets of limiting components. The limiting components include a first electric telescopic rod. The first electric telescopic rod drives the limiting plate at its telescopic end to limit and fix the object to be laser clad, making the object more stable during the laser cladding process. The opening of the assembly slot is equipped with a protective baffle to block the splashes at that position and protect the first electric telescopic rod inside. An opening is also provided for the first electric telescopic rod to extend and retract.

[0017] 3. After the laser cladding of the internally placed object is completed, the limiting component at its location is released so that the limiting component no longer restricts it. Then, the pushing component is opened, and the object is pushed forward by the second electric telescopic rod. Finally, the object is pushed to the discharge port and removed from the anti-splash placement tank. This allows the equipment to also perform unloading operations on the laser-clad objects, improving its functionality.

[0018] Other advantages, objectives and features of this invention will be partly apparent from the following description, and partly understood by those skilled in the art through study and practice of this invention. Attached Figure Description

[0022] Figure 4 This is a top view of the entire utility model. Detailed Implementation

[0023] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can implement it after referring to this specification.

[0024] like Figure 1-4 As shown, a laser cladding head anti-splatter mechanism includes: a laser cladding platform 1, an anti-splatter placement groove 2, a limiting component 3, an anti-splatter shielding component 4, a pushing component 5, and a laser cladding component 6. The laser cladding platform 1 has an anti-splatter placement groove 2 on its outer wall. Limiting components 3 for limiting the displacement of objects are installed on both sides inside the anti-splatter placement groove 2. Anti-splatter shielding components 4 are installed on both sides above the anti-splatter placement groove 2. A pushing component 5 for pushing objects out of the groove is installed at one end of the anti-splatter placement groove 2. A laser cladding component 6 is installed on one side of the anti-splatter placement groove 2. The anti-splatter shielding component 4 includes a rotating shaft 401 installed at both ends of the anti-splatter placement groove 2. An assembly frame 402 is installed on the outer wall of the rotating shaft 401. An anti-splatter baffle 403 is installed between the assembly frames 402. A bracket 404 is installed at one end of the rotating shaft 401. A rotating handle 405 is installed on the outer wall of the bracket 404. One end of the rotating handle 405 is connected to the rotating shaft 401.

[0025] In the above solution, the object to be laser cladding is placed in an anti-splash placement slot. There is a depth between the slot and the laser cladding platform. The depth of the slot restricts the splashes generated during the laser cladding process, making it difficult for the splashes to fly from the slot to the platform and adversely affect other components on the platform. In addition, anti-splash shielding components are installed on both sides above the anti-splash placement slot. The anti-splash shielding components are used as anti-splash baffles to further protect the space above the slot. Even if the splashes fly out of the slot, they will still be blocked by the structure, thereby effectively improving the anti-splash effect at the laser cladding head. The anti-splash baffle can be rotated by a rotating handle to drive the rotating shaft. Through the connection of the assembly frame, the anti-splash baffle can change its anti-splash position as it rotates. The distance between the two anti-splash baffles can be further reduced as needed to improve the anti-splash shielding effect.

[0026] In a preferred embodiment, multiple horizontally spaced assembly slots 201 are provided on both sides of the interior of the splash-proof placement slot 2. A protective baffle 202 is installed on the outer wall of the assembly slot 201. A first electric telescopic rod 301 is installed inside the assembly slot 201. The telescopic end of the first electric telescopic rod 301 extends into the splash-proof placement slot 2 through the through hole on the protective baffle 202. A limit plate 302 is installed at the end of the telescopic end of the first electric telescopic rod 301.

[0027] In the above scheme, the assembly slots in the anti-splash placement slot are arranged horizontally at intervals to install multiple sets of limiting components. Each limiting component includes a first electric telescopic rod. The first electric telescopic rod drives the limiting plate at its telescopic end to limit and fix the object to be laser clad, making the object more stable during the laser cladding process. The opening of the assembly slot is equipped with a protective baffle to block the splashes at that position, protect the first electric telescopic rod inside, and has an opening for the first electric telescopic rod to extend and retract.

[0028] In a preferred embodiment, the other end of the anti-splash placement trough 2 is provided with a discharge port 203, and the pushing assembly 5 includes a mounting base 501. A second electric telescopic rod 502 is installed on the outer wall of the mounting base 501, and a pushing plate 503 is installed on the telescopic end of the second electric telescopic rod 502.

[0029] In the above scheme, after the laser cladding of the internally placed object is completed, the limiting component at its location is released so that the limiting component no longer restricts it. Then, the pushing component is opened, and the object is pushed forward by the second electric telescopic rod. Finally, the object is pushed to the discharge port and removed from the anti-splash placement tank. This allows the equipment to also perform unloading operations on the laser-clad objects, improving its functionality.

[0030] In a preferred embodiment, the laser cladding assembly 6 includes a laser cladding head 604, a third lead screw module 603 mounted above the laser cladding head 604, a second lead screw module 602 mounted at one end of the third lead screw module 603, and a first lead screw module 601 mounted below the second lead screw module 602.

[0031] In the above scheme, the laser cladding head is moved back and forth by the third lead screw module, adjusted in height by the second lead screw module, and moved laterally by the first lead screw module, making the laser cladding head more flexible. The lead screw modules mentioned above are all existing technologies in the field and will not be described in detail here.

[0032] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
