Description

Technical Field

[0001] This utility model relates to the field of nozzle technology for laser cladding equipment, specifically a powder feeding nozzle structure for laser cladding equipment. 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 surface of a substrate and then using a high-energy-density laser beam to fuse the material with a thin layer on the substrate surface, forming a metallurgically bonded cladding layer. Laser cladding equipment is typically equipped with powder feeding nozzles for powder delivery.

[0003] For example, an existing Chinese patent (publication number: CN119615147A) discloses a laser cladding device and method that integrates wire feeding and powder feeding functions. The universal rotation mechanism is installed at the lower end of the robotic arm steering mechanism located at the tail end of the robotic arm. The laser cladding nozzle mounting plate is fixedly connected to the universal rotation mechanism, and the laser cladding nozzle is fixedly connected to the laser cladding nozzle mounting plate.

[0004] However, the laser cladding device with integrated wire and powder feeding functions designed above still has some drawbacks in actual use: Although the laser cladding device with integrated wire and powder feeding functions is equipped with a laser cladding nozzle to facilitate powder feeding, the laser cladding nozzle is fixed to the laser cladding nozzle mounting plate, and the laser cladding nozzle will require maintenance and unclogging due to the adhesion of a large amount of powder after long-term use. Therefore, it is inconvenient for personnel to maintain and repair the nozzle, and it is impossible to disassemble it for maintenance.

[0005] To address these issues, we designed a powder feeding nozzle structure for laser cladding equipment. Utility Model Content

[0006] The purpose of this invention is to provide a powder feeding nozzle structure for laser cladding equipment to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides a powder feeding nozzle structure for laser cladding equipment, including a nozzle assembly. The nozzle assembly includes a nozzle body and a mounting component. The nozzle body is slidably inserted into the bottom of the mounting component. A fixing ring is fixedly sleeved on the nozzle body. A positioning component is fixedly installed on the top of the fixing ring. The top end of the positioning component is slidably inserted into the mounting component. A sliding rod is slidably inserted into the side of the mounting component, with one end extending into the positioning component. A fixing plate is fixedly sleeved on the sliding rod. A spring is provided on one side of the fixing plate, and the other end of the spring is disposed in the mounting component.

[0008] Furthermore, a positioning groove is provided on one side of the positioning member, and one end of the slide rod is slidably inserted into the positioning groove.

[0009] Furthermore, the number of positioning elements is two, and the two positioning elements are respectively fixedly installed at both ends of the top of the fixing ring.

[0010] Furthermore, a pull block is fixedly installed at the end of the slide rod away from the positioning member, and the width of the pull block is much larger than the diameter of the slide rod.

[0011] Furthermore, the mounting component has an installation cavity, a sliding opening, and a fixing opening respectively on its interior, bottom, and one side. The installation cavity, sliding opening, and fixing opening are connected and their number corresponds to that of the positioning component. The sliding rod is slidably inserted into the fixing opening. The side of the spring away from the fixing plate is fixedly installed on the inner side wall of the installation cavity. One end of the positioning component is slidably inserted into the sliding opening.

[0012] Furthermore, two iron blocks are symmetrically fixedly installed on one side of the fixing plate, and two permanent magnets are symmetrically arranged on the inner sidewall of the mounting cavity. The iron blocks and the permanent magnets are magnetically connected in cooperation.

[0013] Furthermore, a limiting groove is provided at the bottom of the mounting component, and the top end of the nozzle body is slidably inserted into the limiting groove.

[0014] Furthermore, a positioning piece is fixedly sleeved at the top position of the mounting component, and a positioning bolt is threaded into the bottom of the positioning piece. There are multiple positioning bolts, and the multiple positioning bolts are threaded into the bottom of the positioning piece at equal intervals.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by pulling the slide rod horizontally, the slide rod can drive the fixed plate to compress the spring, and one end of the slide rod can slide out of the positioning groove. Then, by pulling the nozzle body downward, the nozzle body can be separated from the mounting part, thereby facilitating the maintenance of the mounting part.

[0016] Compared with the prior art, the beneficial effects of this utility model are: when the pull block is pulled, the fixing plate can drive the iron block to resist the permanent magnet. At this time, the permanent magnet can attract the iron block, which can simply limit the fixing plate and the sliding rod, thus facilitating the disassembly and assembly of the parts.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution: a powder feeding nozzle structure for laser cladding equipment, including a nozzle assembly, the nozzle assembly including a nozzle body 1 and a mounting part 2, the nozzle body 1 is slidably inserted into the bottom of the mounting part 2, a fixing ring 3 is fixedly sleeved on the nozzle body 1, a positioning part 4 is fixedly installed on the top of the fixing ring 3, the top end of the positioning part 4 is slidably inserted into the mounting part 2, a sliding rod 5 is slidably inserted into the side of the mounting part 2, and one end extends into the positioning part 4, a fixing piece 6 is fixedly sleeved on the sliding rod 5, a spring 7 is provided on one side of the fixing piece 6, and the other end of the spring 7 is provided in the mounting part 2;

[0024] A positioning groove 8 is provided on one side of the positioning component 4, and one end of the slide rod 5 is slidably inserted into the positioning groove 8.

[0025] In practice, when it is necessary to remove the nozzle body 1 from the mounting part 2 for maintenance, first pull the slide bar 5 horizontally. During this process, the fixing plate 6 will move with the slide bar 5 and compress the spring 7 until one end of the slide bar 5 slides out of the positioning groove 8. Then pull the nozzle body 1 downward so that the positioning part 4 slides out of the mounting cavity 10 and the nozzle body 1 slides out of the limiting groove 15. The nozzle body 1 can then be separated from the mounting part 2, which facilitates maintenance of the mounting part 2. Based on the above principle, the nozzle body 1 can also be easily installed at the bottom of the mounting part 2, achieving the effect of easy disassembly and assembly.

[0026] See Figure 1-4There are two positioning elements 4, and the two positioning elements 4 are fixedly installed at both ends of the top of the fixing ring 3. The setting of the two positioning elements 4 can position the mounting element 2 on both sides of the nozzle body 1, thereby improving the stability of the nozzle body 1 during use.

[0027] See Figure 1-4 A pull block 9 is fixedly installed at the end of the slide rod 5 away from the positioning part 4. The width of the pull block 9 is much larger than the diameter of the slide rod 5. By pulling the pull block 9, the slide rod 5 can be moved, thus allowing for better force application when a person pulls the slide rod 5.

[0028] See Figure 1-4 The mounting component 2 has a mounting cavity 10, a sliding opening 11, and a fixing opening 12 respectively on its interior, bottom, and one side. The mounting cavity 10, sliding opening 11, and fixing opening 12 are connected and their number corresponds to that of the positioning component 4. The sliding rod 5 is slidably inserted into the fixing opening 12. The side of the spring 7 away from the fixing piece 6 is fixedly installed on the inner side wall of the mounting cavity 10. One end of the positioning component 4 is slidably inserted into the sliding opening 11. This ensures that the components inside the mounting component 2 can move normally, thereby avoiding the problem of motion interference.

[0029] See Figure 1-4 Two iron blocks 13 are symmetrically fixed on one side of the fixing plate 6, and two permanent magnets 14 are symmetrically arranged on the inner wall of the mounting cavity 10. The iron blocks 13 and the permanent magnets 14 are magnetically connected.

[0030] In specific implementation, based on the above implementation, when the pull block 9 is pulled, the fixing plate 6 can cause the iron block 13 to abut against the permanent magnet 14. At this time, the permanent magnet 14 can attract the iron block 13, which can simply limit the fixing plate 6 and the slide rod 5, thereby facilitating the disassembly and assembly of the installation component 2.

[0031] It should be noted that, regarding the magnetic connection between the iron block 13 and the permanent magnet 14, the permanent magnet 14 can only attract the iron block 13 when the iron block 13 is close enough to reach half the total distance between the iron block 13 and the permanent magnet 14, so as to avoid the problem of the permanent magnet 14 attracting itself.

[0032] See Figure 1-4 The bottom of the mounting component 2 has a limiting groove 15, and the top end of the nozzle body 1 is slidably inserted into the limiting groove 15. This helps to improve the sealing between the nozzle body 1 and the mounting component 2.

[0033] See Figure 1-4A positioning piece 16 is fixedly sleeved at the top of the mounting component 2. Positioning bolts 17 are threaded into the bottom of the positioning piece 16. Multiple positioning bolts 17 are threaded at equal intervals into the bottom of the positioning piece 16. This allows the mounting component 2 to be easily installed in a suitable position on the laser cladding equipment, and the multiple positioning bolts 17 improve its installation stability.

[0034] Working principle: When using the nozzle body 1, if it is necessary to remove the nozzle body 1 from the mounting part 2 for maintenance, first pull the pull block 9 horizontally, which will cause the pull block 9 to drive the slide rod 5 to slide horizontally. During this process, the fixing plate 6 will move with the slide rod 5 and compress the spring 7 until one end of the slide rod 5 slides out of the positioning groove 8. Then pull the nozzle body 1 downward, so that the positioning part 4 slides out of the mounting cavity 10, and at the same time, the nozzle body 1 slides out of the limiting groove 15, so that the nozzle body 1 can be separated from the mounting part 2, which facilitates the maintenance of the mounting part 2. Based on the above principle, the nozzle body 1 can also be easily installed at the bottom of the mounting part 2, achieving the effect of easy disassembly and assembly.

[0035] During the above operation, when the pull block 9 is pulled, the fixing plate 6 can cause the iron block 13 to come into contact with the permanent magnet 14. At this time, the permanent magnet 14 can attract the iron block 13, which can simply limit the fixing plate 6 and the slide bar 5, thus facilitating the disassembly and assembly of the installation part 2.
