Description

Technical Field

[0001] This invention relates to the field of laser cladding equipment technology, specifically a rotary laser cladding device. Background Technology

[0002] Rotary laser cladding equipment is a high-efficiency laser surface modification / repair equipment for rotating parts (shafts, rollers, cylinders, discs, impellers, etc.). The core is to rotate the workpiece or cladding head, and in conjunction with the laser and powder feeding, form a high-performance coating with metallurgical bonding on the surface of the part.

[0003] When using traditional laser cladding equipment, protective gas needs to be released onto the cladding location on the outer wall of the workpiece during the rotary laser cladding process. Traditional protective gas is often blown directly from a single point or side nozzle. The protective gas is easily diffused into the surrounding air and diluted by the air, making it difficult to form a stable and uniform inert protective environment in the molten pool area. This leads to defects such as oxidation, porosity, inclusions, and cracks caused by the contact between the molten pool and the air, which seriously affects the quality of the cladding layer.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-10 A rotary laser cladding device includes a processing base 1, a mounting base 2 mounted on the top of the processing base 1, an adjusting base 3 rotatably connected to the top of the mounting base 2, a first robotic arm 4 rotatably connected to the outer wall of the adjusting base 3, a second robotic arm 5 rotatably connected to the outer wall of the first robotic arm 4, a rotating base 6 rotatably connected to the outer wall of the second robotic arm 5, a laser base 7 fixedly mounted on the outer wall of the rotating base 6, a laser emitting gun 8 mounted at the end of the laser base 7, a protective component 9 provided on the outer wall of the laser emitting gun 8, a gas guiding component 10 provided on the outer wall of the rotating base 6, a fixed base 11 mounted on the outer wall of the processing base 1, a clamping base 13 movably sleeved on the top of the processing base 1, a workpiece 12 movably sleeved on the outer wall of the fixed base 11, a connecting pipe 14 mounted on the end of the laser base 7 away from the laser emitting gun 8, and a support frame 15 mounted on the top of the second robotic arm 5. In the above structure, by using the fixed seat 11 and clamping seat 13 provided on the top of the processing seat 1, when it is necessary to perform laser cladding on the outer wall of the workpiece 12, the workpiece 12 is installed between the fixed seat 11 and clamping seat 13 and driven so that the workpiece 12 rotates under the support and clamping of the fixed seat 11 and clamping seat 13. Thus, as the workpiece 12 rotates, the outer wall of the workpiece 12 can be laser clad under the action of the laser emitting gun 8.

[0021] In a preferred embodiment: the protective component 9 includes a fixed frame 901, a left adjusting frame 902 is rotatably connected to the outer wall of the fixed frame 901, a right adjusting frame 903 is rotatably connected to the outer wall of the fixed frame 901, an adjusting rod 904 is fixedly mounted on the outer wall of the right adjusting frame 903, a connecting sleeve 905 is fixedly mounted on the end of the adjusting rod 904, and a movable plate 906 is movably sleeved in the inner cavity of the connecting sleeve 905; In the above structure, by rotating the left adjusting frame 902 and the right adjusting frame 903 on the outer walls of both sides of the fixed frame 901, the fixed frame 901, the left adjusting frame 902 and the right adjusting frame 903 form an overall arc shape. Thus, when the laser emitting gun 8 is used to clad the outer wall of the workpiece 12, the fixed frame 901, the left adjusting frame 902 and the right adjusting frame 903 can form a relatively closed space, so that the protective gas can act well on the outer wall of the workpiece 12, and prevent the protective gas from being released directly to the outside and escaping into the air in large quantities. This keeps the molten pool in a stable and uniform inert gas protective environment, thereby continuously and stably cladding the outer wall of the workpiece 12.

[0022] In a preferred embodiment: the outer wall of the movable plate 906 is rotatably connected to the lifting seat 907, the outer wall of the laser seat 7 is fixedly equipped with the drive motor 908, the power output shaft of the drive motor 908 is fixedly equipped with the drive screw 909, the outer wall of the fixed frame 901 is equipped with the sealing plate 9010, the outer wall of the fixed frame 901 is equipped with the side sealing net 9011, and the outer wall of the side sealing net 9011 is fixedly equipped with the deformation rod 9012. In the above structure, by setting the adjusting rods 904 on the outer walls of the left adjusting frame 902 and the right adjusting frame 903 on both sides, when the drive motor 908 drives the drive screw 909, the lifting seat 907 is driven, thereby driving the connecting sleeve 905 and the adjusting rods 904, and thus adjusting the angle of the left adjusting frame 902 and the right adjusting frame 903. This changes the arc angle between the fixed frame 901, the left adjusting frame 902 and the right adjusting frame 903, so that when cladding workpieces 12 of different diameters, the angle between the left adjusting frame 902 and the right adjusting frame 903 and the fixed frame 901 can be adjusted, so that they can better adhere to the outside of the workpiece 12, forming a relatively closed space, so that the protective gas introduced from the outside can better act on the molten pool.

[0023] In a preferred embodiment: adjustment rods 904 are installed on the outer walls of the left adjustment frame 902 and the right adjustment frame 903, the inner wall of the lifting seat 907 is threadedly connected to the outer wall of the drive screw 909, and the two ends of the lifting seat 907 are rotatably connected to the outer walls of the two side moving plates 906 respectively. In the above structure, the drive motor 908 installed on the outer wall of the laser base 7 drives the drive screw 909 to rotate, thereby moving the lifting base 907. The lifting base 907 moves along the outer wall of the drive screw 909, thereby driving the rotation of the moving plate 906 and the connecting sleeve 905. This causes the left adjusting frame 902 and the right adjusting frame 903 to rotate on the outer wall of the fixed frame 901, thus changing the overall curvature. During the change of curvature between the left adjusting frame 902 and the right adjusting frame 903 and the fixed frame 901, the side sealing net 9011 and the deformation rod 9012 will also undergo corresponding deformation, thereby forming a relatively enclosed space.

[0024] In a preferred embodiment: the sealing plate 9010 is made of stainless steel corrugated plate, the side sealing mesh 9011 is woven from stainless steel wire, and the deformation rod 9012 is stainless steel corrugated pipe. In the above structure, the sealing plate 9010 installed between the fixed frame 901, the left adjusting frame 902 and the right adjusting frame 903 will also deform when the left adjusting frame 902 and the right adjusting frame 903 rotate along the outer wall of the fixed frame 901, so as to better form a relatively closed environment. Then, protective gas can be introduced during the cladding process to prevent the protective gas from being released directly into the air and to better enable the protective gas to act on the outer wall of the workpiece 12.

[0025] In a preferred embodiment: the air guiding assembly 10 includes an air guiding pipe 1001, a sealing box 1002 is fixedly mounted on the outer wall of the air guiding pipe 1001, an impeller 1003 is rotatably connected to the inner cavity of the sealing box 1002, an air guiding box 1004 is fixedly mounted on the outer wall of the sealing box 1002, and a release pipe 1005 is installed on the outer wall of the air guiding box 1004. In the above structure, the external protective gas is guided and released through the gas guide pipe 1001, the sealing box 1002, the gas guide box 1004, and the release pipe 1005. The external protective gas is released through the gas guide pipe 1001, the sealing box 1002, the gas guide box 1004, and the release pipe 1005 into the closed space formed by the fixed frame 901, the left adjustment frame 902, and the right adjustment frame 903. This ensures that the outer wall of the workpiece 12 undergoing cladding is in a space filled with inert gas, thereby improving the cladding operation.

[0026] In a preferred embodiment: a connecting plate 1006 is fixedly assembled on the outer wall of the sealing box 1002, a mounting bracket 1007 is installed on the outer wall of the connecting plate 1006, a blowing blade 1008 is rotatably connected to the inner cavity of the mounting bracket 1007, and a connecting shaft 1009 is fixedly assembled at one end of the blowing blade 1008 near the sealing box 1002. In the above structure, the impeller 1003 installed in the inner cavity of the sealing box 1002 can be driven when the protective gas is released into the inner cavity of the sealing box 1002 by the air guide pipe 1001. This causes the impeller 1003 to rotate in the inner cavity of the sealing box 1002, thereby transmitting power downwards and synchronously driving the rotation of the connecting shaft 1009 and the blowing blade 1008. At this time, the blowing blade 1008 can rotate to generate cold air. The cold air will act on the position of the outer wall of the workpiece 12 where the cladding has been completed, to blow away the cladding position and quickly remove the residual slag, oxides, and unbonded small splashes on the surface of the workpiece 12, preventing them from adhering and solidifying, and making the surface of the cladding layer cleaner.

[0027] In a preferred embodiment: the end of the connecting shaft 1009 away from the blowing blade 1008 is connected to the outer wall of the impeller 1003, and the outer wall diameter of the impeller 1003 matches the inner wall diameter of the sealing box 1002; In the above structure, the connecting shaft 1009 between the impeller 1003 and the blowing blade 1008 can transmit the rotational power of the impeller 1003 downwards under the action of the connecting shaft 1009, so that the blowing blade 1008 rotates with the impeller 1003, thereby generating wind. During the process of the laser emitting gun 8 continuously cladding the outer wall of the workpiece 12, protective gas is continuously supplied, thereby continuously generating blowing air to clean the outer wall of the workpiece 12.

[0028] In a preferred embodiment: the release tube 1005 passes through the outer wall of the sealing plate 9010, and the inner cavity of the air guide box 1004 communicates with the inner cavities of the sealing box 1002 and the release tube 1005 respectively. In the above structure, the protective gas in the inner cavity of the gas guide box 1004 is released into the closed space formed by the fixed frame 901, the left adjustment frame 902 and the right adjustment frame 903 under the action of the release pipe 1005 provided on the outer wall of the gas guide box 1004. This makes the position of the workpiece 12 to be clad under the protection of the gas, and then the outer wall of the workpiece 12 can be continuously clad under the action of the laser emitting gun 8.

[0029] In a preferred embodiment: the outer wall of the support frame 15 contacts the outer wall of the connecting pipe 14, the outer wall of the rotating seat 6 is fixedly fitted with a guide plate 16, and the connecting pipe 14 is movably sleeved in the inner cavity of the guide plate 16. In the above structure, the connecting pipe 14 is supported and lifted by the support frame 15 set on the outer wall of the second robotic arm 5, and the connecting pipe 14 and the air guide pipe 1001 are guided by the guide plate 16 set on the outer wall of the rotating seat 6, so that the air guide pipe 1001 stably supplies protective gas into the inner cavity of the sealing box 1002.

[0030] Working principle: During use, when laser cladding is required on workpiece 12, the position of the clamping seat 13 is adjusted, and one end of workpiece 12 is then mounted on the outer wall of the fixed seat 11. The clamping seat 13 is then adjusted again to fix the other end of workpiece 12, completing the clamping and mounting of workpiece 12. Then, the angles of the adjusting seat 3, the first robotic arm 4, the second robotic arm 5, and the rotating seat 6 are adjusted so that the laser emitting gun 8 is aligned with the outer wall of workpiece 12. As the laser emitting gun 8 moves, the protective assembly 9 also moves synchronously. The angles between the left adjusting frame 902 and the right adjusting frame 903 and the fixed frame 901 are adjusted according to the curvature of the outer wall of workpiece 12. The drive motor 908 is then activated to drive... The motor 908 drives the drive screw 909, thereby driving the lifting seat 907. This causes the lifting seat 907 to move up and down along the outer wall of the drive screw 909. During this movement, the moving plate 906 moves within the inner cavity of the connecting sleeve 905, changing the operating angle of the connecting sleeve 905. This, in turn, changes the operating angles of the left adjusting frame 902 and the right adjusting frame 903 on both sides of the fixed frame 901, altering the overall curvature of the fixed frame 901, left adjusting frame 902, and right adjusting frame 903 to match the curvature of the outer wall of the workpiece 12. At this point, the fixed frame 901, left adjusting frame 902, right adjusting frame 903, as well as the closing plate 9010 and the side sealing... The closed-loop system 9011 creates a relatively enclosed space. Protective gas is then released into the inner cavity of the sealed box 1002 through the gas guide pipe 1001. This protective gas flows through the sealed box 1002, the gas guide box 1004, and the release pipe 1005 to the outer wall of the workpiece 12, ensuring the outer wall of the workpiece 12 is covered by the protective gas for laser cladding. The position of the laser emitting gun 8 is then readjusted so that it is perpendicular to the outer wall of the workpiece 12. The equipment can then be started. Under the action of the laser emitting gun 8, laser light and alloy powder are sprayed onto the outer wall of the workpiece 12. The laser emitted by the laser emitting gun 8 is focused on the surface of the workpiece 12, instantly heating a small piece of metal in the workpiece 12 to melt, forming a small pool of liquid metal. Simultaneously, alloy powder is sprayed out. Upon entering the molten pool, the metal powder melts immediately and fuses with the workpiece 12. After the laser emitting gun 8 is removed, the molten pool instantly cools and solidifies, forming a cladding layer. Throughout the cladding process, the relatively enclosed space created by the fixed frame 901, left adjusting frame 902, and right adjusting frame 903 ensures the molten pool is covered by a protective gas. Furthermore, the laser emitting gun 8 and the protective component 9 remain synchronized throughout the cladding process, effectively covering the cladding area of ​​the workpiece 12 with a protective gas. When protective gas is introduced into the inner cavity of the sealed box 1002, it drives the impeller 1003, causing it to rotate within the sealed box 1002.This, in turn, drives the rotation of the connecting shaft 1009 and the blowing blades 1008. During the rotation of the blowing blades 1008, cold air is generated and released onto the cladding areas of the workpiece 12. This cold air cleans and cools the cladding areas, quickly removing residual slag, oxides, and unbonded small splashes from the surface, preventing them from adhering and solidifying. This results in a cleaner cladding surface. Furthermore, the gentle cleaning of the cladding areas on the workpiece 12's outer wall allows for controllable and uniform heat dissipation, reducing localized overheating and heat accumulation in the workpiece 12, minimizing temperature gradients, reducing thermal deformation, decreasing cracking tendency, and improving microstructure uniformity.
