Description

Technical Field

[0001] The present invention relates to the technical field of machining, and specifically relates to a laser welding seam cleaning device. Background Art

[0002] The welding method often used in laser welding is wire filling welding. Laser wire filling welding is a method in which a specific welding material is pre-filled in the weld seam and then irradiated with a laser to melt it, or the welding material is filled while irradiating with a laser to form a welded joint. Laser wire filling welding utilizes the excellent directivity and high power density of the laser beam and other characteristics. Through the optical system, the laser beam is focused in a very small area, so that a heat source area with highly concentrated energy is formed at the welded part, melting the welded object and forming firm solder joints and weld seams.

[0003] After laser wire filling welding, there are impurities such as welding slag and oxides at the weld seam. It is necessary to use a weld seam cleaning device to mechanically clean these defects to prevent these defects from reducing the reliability of the welding and improving the aesthetics of the welding.

[0004] However, during the mechanical cleaning of impurities such as welding slag and oxides by the existing weld seam cleaning devices, it is difficult to clean the through-hole structure. As a result, during the cleaning process, it is difficult to reach and effectively clean the internal area of the through-hole. Therefore, additional manual steps are often required for separate cleaning, which not only increases the processes in the cleaning process but also significantly reduces the overall cleaning efficiency.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-12 , and the present invention provides a technical solution for a laser welding seam cleaning device:

[0034] According to Figures 1-7As shown in the figure, a laser welding seam cleaning device includes an equipment support 1. A first motor 2 and a second motor 4 are fixedly installed on the equipment support 1. The output shaft of the first motor 2 is fixedly installed with a cleaning wheel 3, and the output shaft of the second motor 4 is fixedly installed with a driving wheel 5. Since there is a 1° inclination between the driving wheel 5 and the cylindrical component 6, the surface of the cleaning wheel 3 is made of abrasive material, which is used for mechanically cleaning the oxides and welding slag on the weld seam. The cleanable area of the cleaning wheel 3 is also significantly larger. Therefore, the driving wheel 5 not only drives the cylindrical component 6 to rotate, but also causes the cylindrical component 6 to slowly move along the feeding channel 702. Even when the cleaning path is a spiral line on the outer surface of the cylindrical component 6, the outer surface of the cylindrical component 6 can be cleaned, thus ensuring a comprehensive cleaning of the surface of the cylindrical component 6. A feeding channel 702 is fixedly installed on the equipment support 1. A cylindrical component 6 is movably arranged on the feeding channel 702. A through hole 601 is provided on the surface of the cylindrical component 6, and a conical head 602 is fixedly connected to one end of the cylindrical component 6.

[0035] Among them, a through hole cleaning mechanism is arranged on the equipment support 1. The through hole cleaning mechanism includes a cleaning roller 703 and a third motor 701. A support frame 709 is fixedly installed on the equipment support 1. The third motor 701 is fixedly installed on the surface of the support frame 709. The third motor 701 can drive the cleaning roller 703 to rotate for cleaning the through hole 601. The output shaft of the third motor 701 is fixedly installed with a first rotating shaft 708. One end of the first rotating shaft 708 is fixedly connected to a second gear 707. A rotating connection frame 712 is fixedly installed on the surface of the support frame 709. A second rotating shaft 713 is rotatably connected inside the rotating connection frame 712. One end of the cleaning roller 703 is fixedly connected to a cylinder 704. A second spring 717 is arranged inside the cylinder 704. Through the second spring 717, the sphere 718 can always closely adhere to and follow the surface contour of the cylindrical component 6. And when one end of the cleaning roller 703 is aligned with the through hole 601, the second spring 717 can push the cleaning roller 703 into the through hole 601. A round rod 705 is slidably inserted into the cylinder 704. The round rod 705 is rotatably connected to the rotating part 711 through a bearing 710.

[0036] Among them, a first gear 706 is fixedly connected to the surface of the round rod 705. The rotating part 711 is fixedly connected to the surface of the second rotating shaft 713. Connecting pieces 714 are welded to both the upper and lower ends of the second rotating shaft 713. Side frames 716 are fixedly connected to both sides of the upper and lower ends of the rotating connecting frame 712. A first spring 715 is fixedly connected to the side frame 716. Each two corresponding first springs 715 are fixedly connected to both sides of the connecting piece 714. The cylinder 704 and the round rod 705 need to be squeezed to achieve expansion and contraction, and lateral pressure will occur during the squeezing process. Therefore, the elastic limit of the four first springs 715 is greater than that of the second spring 717. When the cleaning roller 703 rotates, the four first springs 715 can prevent the cleaning roller 703 from rotating out of alignment with the through hole 601, and when the pressure is sufficient, it does not affect the rotation of the cleaning roller 703. The first gear 706 meshes with the second gear 707. When the first gear 706 and the second gear 707 come into contact and mesh, even if tooth hooking occurs, meshing can be achieved by slightly rotating, so as to smoothly complete the power transmission. One end of the second spring 717 is fixedly connected to one end of the round rod 705 located inside the cylinder 704. A sphere 718 is arranged inside one end of the cleaning roller 703. The sphere 718 and the cleaning roller 703 form a ball-and-socket structure. By means of the rotatable sphere 718, the surface of the cylindrical part 6 can be prevented from being scratched when the cleaning roller 703 moves along the surface of the cylindrical part 6.

[0037] During specific use, the cylindrical component 6 is located on the feeding channel 702. While the cleaning wheel 3 cleans the cylindrical component 6, the driving wheel 5 that rotates drives the cylindrical component 6 to rotate and move slowly. The driving wheel 5 not only drives the cylindrical component 6 to rotate but also prompts the cylindrical component 6 to move slowly along the feeding channel 702, thereby ensuring a comprehensive cleaning of the surface of the cylindrical component 6. When the cylindrical component 6 moves to contact the sphere 718 on the cleaning roller 703, it will exert pressure on the cleaning roller 703 and push the sphere 718 to always closely adhere to and follow the surface contour of the cylindrical component 6 through the second spring 717. As the cylindrical component 6 continues to move until one end of the cleaning roller 703 aligns with the through hole 601, the second spring 717 pushes the cleaning roller 703 that matches the size of the through hole 601 into the through hole 601. Since the cleaning roller 703 is a polyurethane rubber roller and is externally coated with a steel wire brush, it has the ability of elastic deformation and the steel wire brush can play a cleaning role. Therefore, when the cleaning roller 703 is inserted into the through hole 601, it can closely adhere to the inner wall of the through hole 601. And the driving wheel 5 and the cylindrical component 6 are inclined at 1°. The cleaning area of the cleaning wheel 3 is relatively large and lower than the deformable degree of the cleaning roller 703. The cleaning roller 703 has a high error tolerance rate and can be driven by the third motor 701 to rotate to perform mechanical cleaning on the through hole 601. As the cylindrical component 6 continues to move and the cleaning roller 703 abuts against the inner wall of the through hole 601, the applied pressure exceeds the elastic limit of the four first springs 715. This change prompts the cleaning roller 703 to rotate in the horizontal direction and smoothly move out of the through hole 601, completing the cleaning operation of the through hole 601.

[0038] According to Figure 4 、 Figure 8 and Figure 9 As shown, a conical cleaning mechanism with cleaning sheets 809 is provided on the equipment support 1. The conical cleaning mechanism consists of cleaning sheets 809, third springs 807 and a fourth motor 801. The fourth motor 801 is fixedly installed on the equipment support 1. The four cleaning sheets 809 are all made of abrasive material and are used for mechanical cleaning of oxides and welding slag on the weld. The fourth motor 801 can drive the four cleaning sheets 809 to perform cleaning operations around the tip weld of the cylindrical component 6. The output shaft of the fourth motor 801 is fixedly connected with a third gear 802. The equipment support 1 is fixedly connected with a sliding support 803. The upper end of the sliding support 803 is slidably connected with an annular slide rail 804. The surface of the annular slide rail 804 is fixedly connected with an annular gear 805. The surface of the annular gear 805 is fixedly connected with a frame 808. Four cleaning brackets 806 are inserted into the interior of the frame 808. The four cleaning sheets 809 are respectively fixedly connected to the long arm ends of the four cleaning brackets 806. The four cleaning sheets 809 can perform all-round mechanical cleaning treatment on the tip of the cylindrical component 6.

[0039] Among them, four third springs 807 are fixedly connected to the frame 808, and the third springs 807 can push the cleaning sheet 809 to fit tightly against the surface of the tip of the cylindrical component 6, thereby enhancing the contact stability and uniformity during the cleaning process. The four third springs 807 are respectively fixedly connected to the short arm ends of the four cleaning brackets 806, and the ring gear 805 is meshed with the third gear 802.

[0040] When used specifically, when the tip of the cylindrical component 6 is inserted into the gap between the four cleaning sheets 809, the fourth motor 801 drives the ring gear 805 to rotate in coordination with the third gear 802. The four cleaning sheets 809 are prompted to rotate around the tip of the cylindrical component 6 to perform a mechanical cleaning operation. As the cylindrical component 6 moves along the preset path, the four cleaning sheets 809 can continuously and automatically clean the tip of the cylindrical component 6 in all directions. The four third springs 807 provide the necessary thrust for each cleaning sheet 809, respectively, so that the cleaning sheet 809 fits tightly to the surface of the tip of the cylindrical component 6, thereby enhancing the contact stability and uniformity during the cleaning process and significantly improving the consistency of the cleaning effect.

[0041] according to Figure 10 , Figure 11 and Figure 12 As shown, a material delivery mechanism is provided on the equipment support 1, and the material delivery mechanism includes a fifth motor 901 and a placement box 902. The fifth motor 901 is fixedly installed on the surface of the equipment support 1, and the placement box 902 is fixedly connected to the surface of the feeding channel 702. The cylindrical component 6 in the placement box 902 can roll to the feeding channel 702 under the action of gravity, thereby realizing automatic and continuous placement of the cylindrical component 6.

[0042] Among them, a first support plate 907 is fixedly connected to the equipment bracket 1, and sprockets 905 are rotatably connected at both ends of the first support plate 907. The output shaft of the fifth motor 901 is fixedly connected to the middle of one of the sprockets 905. The surfaces of the two sprockets 905 are transmission-connected with chains 906. The surfaces of the two sprockets 905 are respectively fixedly connected with a first rubber wheel 903 and a second rubber wheel 904. The elastic first rubber wheel 903 and the second rubber wheel 904 can drive the cylindrical component 6 to move when they rotate, and can adapt to the change in angle caused by the cylindrical component 6 when it changes from an inclined state to a horizontal state.

[0043] Among them, the middle part of the second rubber wheel 904 is fixedly connected with a rotating shaft 3 909, one end of the rotating shaft 3 909 is fixedly connected with a rotating plate 908, one end of the rotating plate 908 is fixedly connected with an inclined pushing piece 910, and a pushing plate 911 is inserted into the interior of the placement box 902. The inclined pushing piece 910 drives the pushing plate 911, so that the pushing plate 911 can push the blocked cylindrical component 6 to prevent the cylindrical component 6 from moving and being blocked.

[0044] Among them, two second support plates 914 are fixedly connected to the surface of the pushing plate 911. Two fourth springs 913 are respectively fixedly connected to the surfaces of the two second support plates 914. The other ends of the two fourth springs (913) are fixedly connected to the surface of the placement box (902). The fourth spring 913 can drive the pushing plate 911 to reset, so as to realize the function of reciprocating pushing. A support shaft 912 is rotatably connected to the side of the pushing plate 911. The rotatable support shaft 912 can reduce the wear on the inclined pushing piece 910.

[0045] During specific use, multiple cylindrical components 6 are arranged in an orderly manner in layers in the placement box 902. The placement box 902 is installed obliquely, and the bottom is inclined, which is convenient for the cylindrical components 6 to naturally roll into the feeding channel 702. Driven by the fifth motor 901, the elastic first rubber wheel 903 and the second rubber wheel 904 start to rotate synchronously, and the cylindrical components 6 are pushed forward in a sliding conveying manner. When the cylindrical component 6 in front of the placement box 902 is successfully transferred, the cylindrical component 6 in the placement box 902 then rolls into the feeding channel 702 under the action of gravity, realizing the automatic continuous placement of the cylindrical component 6. While rotating, the second rubber wheel 904 also drives the third rotating shaft 909 to rotate synchronously, driving the inclined pushing piece 910 on the rotating plate 908 to gently tap the support shaft 912, so that the pushing plate 911 makes a short-distance displacement towards the inside of the placement box 902, which can push the blocked cylindrical component 6 and ensure the smoothness of the feeding process.

[0046] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
