It is mainly used in basic engineering and technological sciences and mechanical engineering fields. Its main functions include laser cutting, drilling, welding, and surface deposition, and it is suitable for precision processing of materials such as metals and ceramics.

[0003] However, in the existing technology, the installation of the coaxial air-blowing protective nozzle structure requires the operation of professional technicians or the use of special tools, which increases labor costs. When the nozzle needs to be cleaned or replaced, the complex installation structure will prolong downtime. In addition, the structure cannot be adjusted according to the optical path parameters of different laser processing machines. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where installation requires the operation of professional technicians or the use of special tools, which increases labor costs and makes it impossible to adjust according to the optical path parameters of different laser processing machines. Therefore, this invention proposes a coaxial air blowing protection nozzle structure for laser processing machines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a coaxial air blowing protection nozzle structure for a laser processing machine, comprising a main body, a through hole in the middle of the main body, a drive mechanism installed inside the main body, and three connecting mechanisms connected to the top of the drive mechanism; The drive mechanism includes a rotating plate, a toothed ring fixedly connected to the outer edge of the bottom of the rotating plate, a track fixedly connected to the top of the rotating plate, a moving block slidably connected to the inner side of the track, and a sliding block fixedly connected to the top of the moving block. The connecting mechanism includes a support plate, the bottom of which is fixedly connected to the top of the sliding block, and a sliding sleeve is slidably connected to the outer surface of the top of the support plate. A clamp is fixedly connected to the side wall of the sliding sleeve, and a threaded rod is rotatably connected to the top of the clamp.

[0006] Preferably, a nozzle structure is fixedly connected to the bottom of the main body, and the rotating plate is rotatably connected to the inner wall of the main body.

[0007] Preferably, the main body surface is provided with a groove, and the groove is slidably connected to the sliding block.

[0008] Preferably, the bottom of the gear ring is connected to three drive gears, which are rotatably connected to the main body.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the rotation of the active gear effectively drives the gear ring, rotating plate and track, so that all parts of the entire connecting mechanism move synchronously, thereby realizing the precise adjustment of the laser processing machine parameters. The coordinated movement of the moving block and the sliding block ensures the stability and accuracy of the equipment and avoids processing errors caused by looseness or misalignment. In addition, the design of the extrusion pad makes the docking with different laser processing machine models more tight, improving the installation accuracy and stability. The sliding sleeve slides flexibly on the support plate, which makes it easy to adjust the height of the extrusion pad and adapt to laser processing machines of different sizes, enhancing the adaptability of the equipment and the convenience of installation. 2. In this utility model, during the adjustment process, the wrench drives the active gear to rotate, causing the gear ring to rotate synchronously, thereby precisely controlling the position of the connecting mechanism, ensuring high precision and stability in each adjustment, and avoiding human error.

[0014] 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.

[0015] 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.

[0016] Example 1: As Figures 1-4 As shown, this utility model provides a coaxial air blowing protection nozzle structure for a laser processing machine, including a main body 1, a through hole 3 in the middle of the main body 1, a drive mechanism 4 installed inside the main body 1, and three connecting mechanisms 2 connected to the top of the drive mechanism 4. The drive mechanism 4 includes a rotating plate 43, a toothed ring 42 fixedly connected to the bottom outer edge of the rotating plate 43, a track 44 fixedly connected to the top of the rotating plate 43, a moving block 45 slidably connected to the inner side of the track 44, and a sliding block 46 fixedly connected to the top of the moving block 45. The connecting mechanism 2 includes a support plate 27, the bottom of which is fixedly connected to the top of the sliding block 46, and a sliding sleeve 26 is slidably connected to the outer surface of the top of the support plate 27. A clamp 24 is fixedly connected to the side wall of the sliding sleeve 26, and a threaded rod 22 is rotatably connected to the top of the clamp 24.

[0017] The specific settings and functions of this embodiment are described below. First, when the drive gear 41 rotates, it applies a force to the gear ring 42. The rotation of the gear ring 42 then drives the rotating plate 43 to rotate. Since the rotating plate 43 is connected to the track 44, the track 44 also rotates, and the applied force is further transmitted to the moving block 45. When the moving block 45 starts to move, the generated force is transmitted to the sliding block 46, which moves linearly under the constraint of the slide groove 11. At this time, the movement of the sliding block 46 not only makes the rotating plate 43 and the track 44 move in coordination, but also realizes the synchronous movement of the three parts of the connecting mechanism 2. This allows for precise adjustment and control of various parameters of the laser processing machine.

[0018] The compression pad 23 can be stably docked and installed with the laser processing machine. This adjustment function ensures that the compression pad 23 can fit tightly with different laser processing machine models, guaranteeing stability and precision during laser processing and avoiding processing errors caused by loosening or misalignment.

[0019] When the sliding sleeve 26 slides on the surface of the support plate 27, the height of the extrusion pad 23 can be flexibly adjusted to adapt to different laser processing machine sizes and requirements. This improves the convenience and adaptability of the installation process, not only reducing the complexity of installation but also making the equipment more widely applicable in different environments.

[0020] Example 2: Figures 2-4 As shown, a nozzle structure 5 is fixedly connected to the bottom of the main body 1, and a rotating plate 43 is rotatably connected to the inner wall of the main body 1. A sliding groove 11 is formed on the surface of the main body 1, and the sliding groove 11 is slidably connected to the sliding block 46. Three drive gears 41 are meshed with the bottom of the gear ring 42, and the drive gears 41 are rotatably connected to the main body 1. A locking rod 25 is threadedly connected to the side wall of the sliding sleeve 26, and one end of the locking rod 25 abuts against the side wall of the support plate 27. A handle 21 is fixedly connected to the top of the threaded rod 22, and a compression pad 23 is fixedly connected to the bottom of the threaded rod 22.

[0021] The overall effect of this embodiment is that, during operation, when precise adjustments to the system are required, a wrench is first inserted into the drive gear 41, and rotating the wrench drives the drive gear 41 to rotate. This causes the drive gear 41 and its connected gear ring 42 to rotate synchronously, thereby precisely controlling the positions of the three connecting mechanisms 2. Through gear transmission, high-precision adjustment of the connecting mechanisms 2 is ensured, and errors caused by human operation are avoided, making each adjustment more stable and efficient.

[0022] The locking lever 25 plays a crucial role when adjusting the height of the sliding sleeve 26. During rotation, the locking lever 25 contacts the side wall of the support plate 27, ensuring that the sliding sleeve 26 remains fixed at the required height. This ensures that the height of the clamp 24 is accurately maintained within the preset range, preventing adverse consequences due to positional deviations.

[0023] During the locking process, turning the handle 21 transmits rotational force to the threaded rod 22, causing it to rotate and adjust its position. The rotation of the threaded rod 22 directly controls the position of the compression pad 23, thereby precisely adjusting the compression force of the clamp 24. Through this precise control, the compression pad 23 can tightly cooperate with the clamp 24 for compression positioning, ensuring precise fit of all components during installation.

[0024] The operating method and working principle of this device are as follows: When the drive gear 41 is driven to rotate by an external force, it applies torque to the gear ring 42 through meshing transmission, causing the gear ring 42 to rotate synchronously. The gear ring 42 is rigidly connected to the rotating plate 43, so the rotating plate 43 moves in a circular motion, and the track 44 fixed at its edge also rotates synchronously. During the rotation of the track 44, a tangential force is applied to the moving block 45 through the arc-shaped groove, causing the moving block 45 to move along the groove direction. The moving block 45 and the sliding block 46 are connected by a transmission rod. When the moving block 45 moves, it transmits force to the sliding block 46, causing the sliding block 46 to reciprocate linearly under the linear guidance of the slide groove 11. Since the sliding blocks 46 of the three connecting mechanisms 2 are connected by linkage rods, the synchronous translation of the three connecting mechanisms 2 can be realized, thereby adaptively adjusting according to the width dimensions of different laser processing machines to ensure that the extrusion pad 23 can fit tightly against the equipment shell.

[0025] For vertical adjustment, the sliding sleeve 26 can slide up and down along the guide rail of the support plate 27, driving the extrusion pad 23 to adjust its height. After the sliding sleeve 26 moves to the target position, the locking rod 25 is rotated so that the wedge block at its end presses against the side wall of the support plate 27, using friction to lock the vertical position. Precise horizontal positioning is achieved by rotating the handle 21, which is coaxially connected to the threaded rod 22. When the handle 21 is rotated, the threaded rod 22 rotates and moves axially within the threaded hole, pushing the extrusion pad 23 to move horizontally. When the extrusion pad 23 is in contact with the equipment surface, the clamping force of the fixture 24 enables stable installation and rapid positioning of the laser processing machine.

[0026] 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.
