Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an anti-clogging laser cladding nozzle. Background Technology

[0002] Laser cladding is a process in which a laser beam is emitted from a nozzle, simultaneously or with pre-placed materials, to add external materials to the molten pool formed after laser irradiation of the substrate. Both materials then rapidly solidify to form a coating layer. This process can significantly improve the surface properties of the substrate material. The nozzle, as a crucial component of laser cladding coating technology, has a vital impact on coating quality and work efficiency due to its performance and stability.

[0003] In response, Chinese utility model patent CN217459605U discloses a laser cladding head for easy powder filling, comprising a laser cladding head, a nozzle, a connector, and a vertical tube. The nozzle is installed at the bottom of the laser cladding head, and connectors are inserted into both sides of the outer wall of the nozzle. A vertical tube is fixedly connected inside the nozzle. The laser cladding head for easy powder filling also includes an anti-clogging component installed inside the nozzle; wherein the anti-clogging component is used to clear the powder inside the nozzle. This utility model, through the coordinated use of the outer shell, support block, adjusting tube, fiber optic interface, nozzle, connector, and vertical tube, achieves both laser cladding and powder ejection. Through the coordinated use of the turntable, stirring rod, support rod, and ring, it enables rapid clearing of powder deposits and blockages inside the nozzle during operation, eliminating the need to replace the nozzle.

[0004] The laser cladding nozzle is equipped with an anti-clogging component. After the machine stops due to blockage, the ring is manually rotated to drive the turntable to rotate inside the nozzle via the support rod. When the turntable rotates, it drives the stirring rod to rotate inside the nozzle, thus completing the unblocking work. The manual rotation operation is quite laborious.

[0005] To address this issue, we propose an anti-clogging laser cladding nozzle. Utility Model Content

[0006] The purpose of this invention is to provide an anti-clogging laser cladding nozzle to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-clogging laser cladding nozzle, comprising a nozzle, with connectors internally threaded to both sides of the nozzle, and fixing blocks fixedly attached to both sides of the nozzle, a motor fixedly mounted on the bottom surface of one of the fixing blocks, a rotating rod fixedly attached to the motor shaft, a gear fixedly attached to the outer surface of the rotating rod, a gear ring meshing with one side of the gear, a stirring rod fixedly attached to both ends of the inner side of the gear ring, an installation groove formed on the inner wall of the nozzle, the gear ring contacting the installation groove, a limiting ring block fixedly attached to the bottom surface of the gear ring, a rotating ring groove formed on the bottom surface of the installation groove, and the limiting ring block rotatably connected to the rotating ring groove.

[0008] Preferably, a connecting groove is formed in one of the fixing blocks, and the connecting groove and the mounting groove are internally connected.

[0009] Preferably, a vertical tube is fixedly installed inside the nozzle.

[0010] Preferably, the nozzle is threadedly connected to an adjustment tube at its top.

[0011] Preferably, a feed inlet is provided on one side of the connector, the feed inlet is connected to the inside of the nozzle, and a filter plate is detachably installed inside the feed inlet.

[0012] Preferably, a cover is detachably mounted on the bottom surface of one of the fixing blocks, and the motor is located inside the cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention incorporates a motor, rotating rod, gears, gear ring, stirring rod, and limiting ring block. When a blockage occurs, the motor drives the rotating rod and gears to rotate, which in turn drives the gear ring to rotate. This causes the stirring rod to rotate inside the nozzle, thus clearing the blockage and effectively preventing further blockages. Compared to manual operation, this method is more labor-saving and convenient. Attached Figure Description

[0021] Example 1:

[0022] Please see Figure 1-4 This is the first embodiment of the present invention, which provides a technical solution: an anti-clogging laser cladding nozzle, including a nozzle 1, with connectors 3 internally threaded on both sides of the nozzle 1, and fixing blocks 4 fixedly attached to both sides of the nozzle 1. A motor 6 is fixedly mounted on the bottom surface of one of the fixing blocks 4, and a rotating rod 7 is fixedly attached to the shaft of the motor 6. A gear 8 is fixedly attached to the outer surface of the rotating rod 7, and a gear ring 9 is meshed with one side of the gear 8. A stirring rod 11 is fixedly attached to both ends of the inner side of the gear ring 9. An installation groove 10 is opened in the inner wall of the nozzle 1, and the gear ring 9 contacts the installation groove 10. A limiting ring block 15 is fixedly attached to the bottom surface of the gear ring 9. A rotating ring groove 101 is opened in the bottom surface of the installation groove 10. The limiting ring block 15 is rotatably connected to the rotating ring groove 101, which can effectively limit the rotation of the gear ring 9. When the gear ring 9 rotates, the limiting ring block 15 rotates with it in the rotating ring groove 101, thereby improving the stability of the rotation of the gear ring 9.

[0023] Example 2:

[0024] Please see Figure 1-4 This is the second embodiment of the present utility model. This embodiment is based on the previous embodiment, in which a connecting groove 41 is formed in one of the fixing blocks 4, and the connecting groove 41 and the mounting groove 10 are internally connected.

[0025] A vertical tube 12 is fixedly installed inside the nozzle 1.

[0026] The nozzle 1 is threadedly connected to the top of the regulating tube 2.

[0027] A feed inlet 14 is provided on one side of the connector 3. The feed inlet 14 is connected to the inside of the nozzle 1. A filter plate 5 is detachably installed inside the feed inlet 14. The filter plate 5 can filter impurities in the powder to prevent clogging. The filter plate 5 is easy to install and remove. In use, the powder connecting pipe is connected to the connector 3. After the connection is completed, the laser is controlled by the external control unit to be emitted through the vertical pipe 12 and the bottom of the nozzle 1. At the same time as the laser is emitted, the protective gas is also ejected. After being ejected, the powder enters the bottom of the nozzle 1 through the feed inlet 14 of the connector 3. After entering, it is ejected at the same time as the protective gas to carry out the cladding work.

[0028] One of the fixing blocks 4 has a cover 13 that can be detachably installed on its bottom surface. The motor 6 is located inside the cover 13, which can effectively protect the motor 6.

[0029] Example 3:

[0030] Please see Figure 1-4 This is the third embodiment of the present invention. This embodiment is based on the above two embodiments. In actual use, when the amount of powder sprayed from the nozzle decreases, the powder inside the nozzle will become clogged. After the clog occurs, the machine is stopped. The motor 6 is connected to an external power supply. After the machine stops, the controller drives the motor 6 to rotate the rotating rod 7 and the gear 8, and at the same time, it drives the gear ring 9 to rotate, which drives the stirring rod 11 to rotate inside the nozzle 1, thereby completing the unblocking work and effectively preventing clogging. Compared with manual rotation operation, it is more labor-saving and convenient.
