Currently, in some laser cladding processes, splatter debris often appears around the high-precision laser cladding nozzle. This splatter debris affects the coating quality and surface finish, leading to a reduction in product quality. Utility Model Content

[0027] Example
[0028] like Figures 1 to 6 As shown, this utility model proposes a high-precision laser cladding nozzle, including a laser cladding nozzle body 1, a support block 11 for supporting a suction tube 5 fixedly connected to the outer wall of the laser cladding nozzle body 1, and further including: a spiral sleeve 12 fixedly sleeved on the bottom end of the laser cladding nozzle body 1; a chip removal mechanism spirally sleeved on the spiral sleeve 12 for absorbing the debris generated by the laser cladding nozzle body 1, the chip removal mechanism including a dust collection cover 2 spirally connected to the spiral sleeve 12; a baffle mechanism set on the chip removal mechanism to prevent the absorbed debris from falling out; and an adjustment mechanism installed at the bottom of the dust collection cover 2 to adjust the suction force of the chip removal mechanism by rotation, the function of which is to adjust the powder absorption rate according to the characteristics of different materials and process requirements, avoid excessive or insufficient powder supply, and ensure the uniformity and density of the cladding layer.
[0029] Furthermore, the lint removal mechanism includes a screw cap 4 located on top of the suction cover 2. Multiple protrusions 41 arranged in a circular array are fixedly connected to the lower surface of the screw cap 4, providing leverage for the hand. A suction tube 5 is fixedly connected to the upper surface of the screw cap 4. The suction tube 5 is made of soft material, and the end of the suction tube 5 away from the suction cover 2 is connected to a vacuum pump. The suction tube 5 of a vacuum pump typically refers to a piping system connected to the vacuum pump for guiding gas flow. In vacuum pump applications, the suction tube 5 draws external gas into the pump body or transfers the negative pressure generated by the pump body to the object to be suctioned. A filter head 42 is fixedly connected to the end of the suction tube 5 near the screw cap 4. The filter head 42 is a pre-filter, which can be a HEPA filter to capture fine debris particles, ensuring that not too many fine particles enter the suction tube 5. The end of the filter head 42 away from the suction tube 5 passes through the screw cap 4, allowing for easy cleaning of dust inside the suction cover 2. The bottom of the dust collection cover 2 has multiple dust collection holes 21 arranged in a circular array for dust collection.
[0030] The baffle mechanism includes a pair of rotating grooves 24 formed within the suction hole 21. Each rotating groove 24 has a rotating hole 27 at both ends. A pair of rotating cover plates 22, which rotate downwards under gravity, are rotatably connected inside the suction hole 21. The rotating cover plates 22 are made of rubber, and their maximum upward rotation angle is less than 90°, allowing them to automatically rotate downwards and block the suction hole 21 when not subjected to suction. Rotating rods 26, which engage with the rotating holes 27, are fixedly connected to both ends of the rotating cover plates 22.
[0031] Furthermore, the adjustment mechanism includes an adjustment baffle 3 located at the bottom of the dust collection cover 2. The lower surface of the adjustment baffle 3 has multiple protrusions 32 arranged in a circular array. Each protrusion 32 has a pair of arc-shaped dust-guiding surfaces 33 that facilitate the entry of debris into the baffle holes 31. A raised edge 35 is fixedly connected to the bottom of the adjustment baffle 3, ensuring that all debris in the bottom area of the adjustment baffle 3 is covered and sucked into the baffle holes 31. A rotating groove 23 is provided at the bottom of the dust collection cover 2, and multiple baffle holes 31 corresponding to the dust collection holes 21 are provided on the adjustment baffle 3. The baffle holes 31 are slightly larger than the dust collection holes 21; the suction force of the dust collection holes 21 is maximized only when the dust collection holes 21 and the baffle holes 31 are completely aligned. A rotating locking block 34, which engages with the rotating groove 23, is fixedly connected to the upper surface of the adjustment baffle 3.
[0032] In this embodiment, when a high-precision laser cladding nozzle is required, such as... Figure 1As shown, when the laser cladding nozzle body 1 is in use, simply activating the suction pipe 5 generates suction. This suction passes through the filter head 42 and the dust collection cover 2, causing the multiple dust collection holes 21 at the bottom of the dust collection cover 2 to generate suction. At this time, each pair of rotating cover plates 22 within the dust collection holes 21 rotates around the rotating rod 26 within the rotating hole 27, causing the rotating cover plates 22 to open and generate suction, thereby drawing the debris generated at the bottom of the laser cladding nozzle body 1 into the dust collection cover 2. When the suction pipe 5 does not generate suction, the pair of rotating cover plates 22 within the dust collection holes 21 will rotate downwards under the influence of gravity and return to the state of blocking the dust collection holes 21, preventing debris from flowing out of the dust collection holes 21. When it is necessary to adjust the size of the dust collection holes 21, simply rotate the protrusion 32 at the bottom of the adjusting baffle 3. The protrusion 32 drives the adjusting baffle 3 to rotate within the rotating groove 23 via the rotating latch 34. At this time, the more the multiple baffles 31 on the adjusting baffle 3 overlap with the dust suction holes 21 at the bottom of the dust suction cover 2, the greater the suction force generated by the dust suction holes 21, and vice versa. When it is necessary to clean the debris inside the dust suction cover 2, simply rotate the protrusion 41 on the screw cap 4. The protrusion 41 drives the screw cap 4 and the filter head 42 to rotate. Since the screw cap 4 and the dust suction cover 2 are connected by a screw, the lower surface of the screw cap 4 can first disengage from the retaining ring 25 and then disengage from the top of the dust suction cover 2, so that the debris inside the dust suction cover 2 can be cleaned.
[0033] The preferred embodiments of this utility model described above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
