[0002] Laser cladding metal surface strengthening equipment is an advanced surface engineering technology. Its core principle is to melt synchronously transported alloy powder or wire with a high-energy laser beam to form a metallurgically bonded strengthening coating on the substrate surface. With the development of high-power lasers, CNC systems and materials science, it has gradually matured and has now become a key surface modification method in aerospace, energy equipment, automobile manufacturing and other fields.

[0003] Currently, during the laser cladding process, the powder feeding tube may experience slight blockage or powder agglomeration due to moisture, resulting in unstable powder feeding and affecting the uniformity of the cladding layer. This problem is often not immediately noticeable because the initial manifestation may only be a slight fluctuation in the thickness or surface quality of the cladding layer. However, long-term accumulation can lead to a decline in coating performance and even defects such as porosity or poor bonding. Utility Model Content

Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example

[0029] Reference Figures 1-4 This is an embodiment of the present invention, which provides a laser cladding metal surface strengthening treatment device, comprising,

[0030] The operating mechanism 100 includes a base 110, a robotic arm 120 fixedly mounted on the top of the base 110 for operation, and a laser assembly 130 fixedly mounted on the outside of the robotic arm 120 for laser cladding of metal surfaces.

[0031] The vibration anti-blocking mechanism 200 includes a mounting plate 210 fixedly installed on the outside of the robotic arm 120, a powder hopper 220 fixedly installed in the inner cavity of the mounting plate 210 for placing powder, a shaft 230 rotatably installed in the inner cavity of the powder hopper 220, a damping assembly 240 provided at the end of the shaft 230, and a swing assembly 250 provided on the outside of the damping assembly 240 for cooperative use.

[0032] The damping assembly 240 includes a fixed ring plate 241 fixedly sleeved on the outside of the shaft 230, a housing 242 fixedly installed on the outside of the fixed ring plate 241, and a toothed column 243 fixedly installed in the inner cavity of the housing 242 for generating misaligned vibration during rotation.

[0033] The vibration-type anti-blocking mechanism 200 drives the damping component 240 to rotate via the servo motor 280, which in turn drives the swing component 250 to move, keeping the powder in the powder hopper 220 in a loose and flowing state, effectively preventing the powder from getting damp and clumping or the powder feeding pipe 134 from getting blocked. Compared with the traditional powder feeding system, the vibration-type anti-blocking mechanism 200 can automatically adjust the powder flowability without interrupting the laser cladding process, ensuring uniform and stable powder feeding, thereby improving the density and bonding strength of the cladding layer and reducing the generation of defects such as pores and cracks. In addition, it can be directly integrated into the robotic arm 120 without affecting the overall operational flexibility of the equipment.

[0034] The damping assembly 240 consists of a fixed ring plate 241, a housing 242, a toothed column 243, and a toothed sleeve 244. Its core function is to generate intermittent resistance during rotation, resulting in slight vibration.

[0035] Specifically, the damping assembly 240 also includes a toothed sleeve 244 that engages with the outside of the toothed post 243 to achieve damped rotation, and a movable channel 245 opened on the outside of the housing 242.

[0036] When the servo motor 280 drives the housing 242 to rotate, the toothed column 243 and the toothed sleeve 244 mesh with each other. However, due to the design of the toothed structure, the two will continuously misalign during rotation, thus generating a periodic damping effect. This damping effect can not only prevent the powder from being compacted and agglomerated due to long-term static storage, but also transmit the vibration to the inner wall of the powder hopper 220, so that the powder always remains in a loose state and avoids the powder feeding pipe 134 from being blocked.

[0037] Furthermore, the swing assembly 250 includes a horizontal plate 251 fixedly connected to the outside of the toothed sleeve 244, a toothed protrusion 252 fixedly installed on the outside of the horizontal plate 251, a bracket 253 fixedly installed on the other side of the horizontal plate 251, and a limiting channel 254 opened in the inner cavity of the bracket 253. The swing assembly 250 also includes a limiting plate 255 movably locked in the inner cavity of the limiting channel 254, a rotating shaft 256 rotatably installed on the outside of the limiting plate 255, and a rotating plate 257 fixedly installed at the end of the rotating shaft 256 to swing and turbulent the powder.

[0038] The oscillating assembly 250 consists of a horizontal plate 251, toothed protrusions 252, a bracket 253, a limiting plate 255, a rotating shaft 256, and a rotating plate 257. Its main function is to actively agitate the powder in the powder hopper 220 under the drive of the damping assembly 240. When the damping assembly 240 rotates, the horizontal plate 251 drives the toothed protrusions 252 to move along the toothed ring 260. Due to the meshing action between the toothed protrusions 252 and the toothed ring 260, the horizontal plate 251 will swing up and down while rotating, and then drive the rotating plate 257 to swing back and forth in the powder hopper 220 through the rotating shaft 256. This oscillating action can effectively break up the clumps of powder and promote the uniform flow of powder, avoiding the powder feeding pipe 134 from being blocked due to powder accumulation.

[0039] Preferably, the vibration anti-blocking mechanism 200 also includes a toothed ring 260 fixedly installed in the inner cavity of the powder hopper 220, a cover plate 270 fixedly installed at the opening of the powder hopper 220, a servo motor 280 fixedly installed on the outside of the cover plate 270, and a feed pipe head 290 fixedly installed on the outside of the cover plate 270. The output end of the servo motor 280 is fixedly connected to the outside of the housing 242, and the toothed protrusion 252 meshes with the toothed ring 260.

[0040] The toothed ring 260 is fixed inside the powder hopper 220 and meshes with the toothed protrusion 252, enabling the oscillating component 250 to generate regular vibrations during rotation. This design not only enhances the vibration effect but also ensures that the oscillation amplitude is controllable, preventing powder splashing or equipment structural fatigue due to excessive vibration. At the same time, the toothed structure of the toothed ring 260 can be adjusted according to actual needs to adapt to the flowability requirements of different powders, improving the applicability of the mechanism. The servo motor 280, as a power source, can precisely control the rotation speed of the damping component 240, thereby adjusting the vibration frequency to meet the powder feeding requirements under different working conditions. The feed pipe head 290 adopts a sealed design to prevent external moisture from entering the powder hopper 220, further reducing the risk of powder becoming damp and clumping.

[0041] Furthermore, the laser assembly 130 includes a coaxial powder feeding and cladding head 131 fixedly mounted at the end of the robotic arm 120, a support ring sleeve 132 fixedly mounted on the outside of the coaxial powder feeding and cladding head 131, an airflow branch pipe 133 fixedly mounted in a ring shape on the outside of the coaxial powder feeding and cladding head 131, a powder feeding pipe 134 fixedly mounted on the outside of the coaxial powder feeding and cladding head 131, and a laser head 135 fixedly mounted at the end of the coaxial powder feeding and cladding head 131.

[0042] Among them, the coaxial powder feeding and cladding head 131 of the laser component 130 works in conjunction with the vibration anti-blocking mechanism 200 to ensure that powder feeding and laser cladding are carried out synchronously. The design of the support ring 132 and the airflow branch pipe 133 not only improves the accuracy of powder feeding, but also reduces the adhesion of powder in the powder feeding pipe 134 through airflow assistance, further reducing the risk of blockage. The precise focusing capability of the laser head 135 combined with the stable powder feeding system ultimately achieves the preparation of a high-quality, defect-free cladding layer.

[0043] In use, the servo motor 280 drives the housing 242 of the damping component 240 to rotate, and the periodic damping vibration is generated by the meshing of the toothed column 243 and the toothed sleeve 244. This vibration is transmitted to the swing component 250, which causes the horizontal plate 251 to drive the toothed protrusion 252 to move along the toothed ring 260, generating an up-and-down swinging motion. In turn, the rotating shaft 256 drives the rotating plate 257 to swing back and forth in the powder hopper 220, continuously breaking up any powder that may clump together.

[0044] Meanwhile, with the assistance of the airflow branch pipe 133, the coaxial powder feeding and cladding head 131 of the laser component 130 accurately delivers the anti-clogging powder to the action area of ​​the laser head 135, achieving precise synchronization between powder delivery and laser cladding, and finally obtaining a dense and uniform high-quality cladding layer.

[0045] In summary, the innovative vibration-type anti-blocking mechanism 200, in synergy with the laser component 130, effectively solves the technical problems of powder agglomeration and uneven powder feeding in traditional laser cladding processes. The vibration-type anti-blocking mechanism 200 drives the damping component 240 to generate regular vibration through the servo motor 280, which in turn drives the swing component 250 to continuously agitate the powder in the powder hopper 220, ensuring that the powder always remains in a loose and flowing state. This not only significantly improves the stability of powder feeding but also avoids defects in the cladding layer quality caused by powder blockage. At the same time, the entire system structure can be directly integrated into the robotic arm 120, ensuring both the flexibility of equipment operation and the realization of automated anti-blocking function.
