Description

Technical Field

[0001] The present invention belongs to the technical field of welding, and specifically discloses a laser welding device for the maintenance of aviation mechanical parts. Background Art

[0002] When aviation machinery is in use, it is necessary to regularly maintain the oil rail of the aviation machinery. If the oil rail is damaged, a laser welding device is required to weld the oil rail. After retrieval, the existing patent document CN118478092B shows a laser welding device for oil rail processing that can be adjusted in multiple directions for the oil rail welding of aviation machinery. In this device, the pipeline is placed on the third support and the second support. The output end of the hydraulic cylinder drives the pressing block to fit on the pipeline. The output end of the second driving motor drives two moving blocks, and each drives a pipeline to move towards the middle position of the first support through a third support, so that the ends of the two pipelines are fitted together. Subsequently, driving the spur gear ring drives the pipeline to perform a circular motion through the rotating ring, which can drive the two pipelines to perform full-range welding. When this device is actually used, it can indeed make the ends of the two pipelines abut against each other, and at the same time, it can also achieve full-range welding of the two abutting pipelines. However, in the actual use process, there are still some deficiencies, such as: Although the driving spur gear ring in this device can drive the pipeline to perform a circular motion through the rotating ring, the spur gear rings are distributed at the opposite parts of the two pipelines. This leads to the way the spur gear ring drives the pipeline is from both sides to the middle. At the same time, there is no transmission structure at the welding ends of the two pipelines. If the third support at the welding end of the pipeline adheres to welding slag, the welding slag will affect the rotation of the pipeline on the third support, which will cause the welding parts of the two pipelines to rotate out of sync, and then cause the welding parts of the two pipelines to not always be in a pressed state, affecting the welding accuracy of the device for the pipeline.

[0003] Therefore, we propose a laser welding device for the maintenance of aviation mechanical parts to solve the problem that the welding parts of the two pipelines rotate out of sync, resulting in the welding parts of the two pipelines not always being in a pressed state.

DETAILED DESCRIPTION OF THE INVENTION

[0021] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific embodiments.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0023] The existing welding device usually transmits the oil rail pipeline in a way that it is transmitted from both sides to the middle. At the same time, there is no transmission structure at the welding ends of the two pipelines, which easily leads to the asynchronous rotation of the welded parts of the two pipelines, resulting in the inability of the welded parts of the two pipelines to always be in a compressed state, affecting the welding accuracy of the device for the pipeline. To solve the above problems, the following structure is proposed.

[0024] Embodiment 1: Please refer to Figures 1 - 3 As shown in the figure, the present invention provides a technical solution: The present invention is a laser welding device for repairing aviation mechanical parts, including a welding device 1 and a mounting table 2 fixedly connected to the welding device 1. Adjusting sliders 3 are symmetrically and fixedly connected to the mounting table 2. The output end of the adjusting slider 3 is fixedly connected to a support structure 6. A plug-in member 8 is rotatably connected to the support structure 6. A transmission structure and the support structure 6 are detachably connected to the plug-in member 8. A first clamping head 11 is fixedly connected to the end of one of the plug-in members 8, and a second clamping head 12 is fixedly connected to the end of the other plug-in member 8. The first clamping head 11 and the second clamping head 12 are clamped. The support structure 6 includes support pipes 71 evenly distributed on the plug-in member 8. A pipeline member 5 is sleeved on the support pipe 71. When the laser welding device is actually used, the user pre-sleeves the pipeline member 5 on the support pipe 71, which can realize that the two relatively welded pipeline members 5 are distributed near the welding end of the laser welding device. When the output end of the adjusting slider 3 drives the pipeline members 5 on the plug-in member 8 to approach each other through the support structure 6, when the pipeline members 5 on the plug-in member 8 are in contact with each other, the first clamping head 11 and the second clamping head 12 can be clamped. At this time, the two plug-in members 8 can be assembled into an integral rod-shaped structure. When the transmission structure drives the plug-in member 8 to rotate, the plug-in member 8 can also drive the two pipeline members 5 to rotate synchronously, which can avoid the phenomenon of asynchronous rotation at the welding ends of the two pipeline members 5. Embodiment 2: Please refer to Figures 1 - 8 As shown in the figure, based on Embodiment 1, the present invention provides a technical solution. Different from Embodiment 1, this embodiment can avoid the pipeline member 5 containing more welding fumes and hot air, improve the welding quality of the pipeline member 5, and avoid damage to the support pipe 71 at the same time. A connecting elbow pipe 7 is fixedly connected between every two support pipes 71. An air guide pipe 710 is fixedly connected to the support pipe 71. The inner cavity of the air guide pipe 710 is communicated with the inner cavity of the plug-in member 8. The connecting elbow pipe 7 is an arc-shaped tubular structure. When the connecting elbow pipe 7 is fixed between every two support pipes 71, it can avoid the deformation of the support pipe 71. The air guide pipe 710 is a metal tubular structure. The air guide pipe 710 is fixedly connected to the support pipe 71, which can improve the support strength of the support pipe 71 for the pipeline member 5.

[0025] The support structure 6 further includes a sleeve pipe 74 fixedly connected to the socket 8, the support pipes 71 are fixedly connected to the sleeve pipe 74 at equal intervals, an air collecting cavity 79 is formed at one end of the support pipe 71 facing away from the sleeve pipe 74, the air collecting cavity 79 communicates with the inner cavity of the air guide pipe 710, exhaust holes 72 are formed in the support pipe 71, and the exhaust holes 72 communicate with the inside of the air collecting cavity 79; By arranging the support pipes 71 on the sleeve pipe 74 at equal intervals, the support pipes 71 can support the pipe fitting 5 with uniform force, which can avoid the deformation of the welding end of the pipe fitting 5 during welding. At the same time, when the pipe fitting 5 is welded on the socket 8, the welding fume and hot air inside the pipe fitting 5 can enter the inside of the air collecting cavity 79 through the exhaust holes 72, and finally the hot air and welding fume inside the air collecting cavity 79 can be discharged to the outside through the socket 8.

[0026] The inner cavities of the support pipe 71 and the air guide pipe 710 communicate through the inner cavities of the sleeve pipe 74 and the socket 8. A sliding cavity 76 is formed inside the support pipe 71, and a sliding ring 78 is slidably connected inside the sliding cavity 76; When the support pipe 71 supports the pipe fitting 5, the air guide pipe 710 can drain the welding fume and hot air inside the air collecting cavity 79 to the inside of the socket 8. When the external device discharges the air inside the socket 8, the welding fume and hot air can be quickly dissipated.

[0027] Embodiment Three: Please refer to Figures 2 - 8 As shown, based on Embodiment Two, the present invention provides a technical solution. Different from Embodiment Two, this embodiment can drive the abutting head 73 to support the pipe fitting 5, and can realize the clamping of the pipe fitting 5 with different diameters by the support pipe 71, so as to realize the stable welding of the welding end of the pipe fitting 5; A connecting spring 77 is fixedly connected between the sliding ring 78 and the bottom wall of the inner cavity of the sliding cavity 76. A plugging rod 75 is fixedly connected to the sliding ring 78, and the upper end of the plugging rod 75 penetrates through the support pipe 71.

[0028] An abutting head 73 is fixedly connected to the upper end of the plugging rod 75, and a magnetic head 711 is fixedly connected to the lower end of the plugging rod 75. The magnetic head 711 is inserted into the inside of the sleeve pipe 74; The sliding ring 78 can drive the plugging rod 75 to slide inside the support pipe 71, so as to realize the support of the pipe fitting 5 with different diameters by the plugging rod 75 driving the abutting head 73. When the sliding ring 78 drives the plugging rod 75 to move inside the support pipe 71, the connecting spring 77 can store energy and work, and the repulsive force generated by the connecting spring 77 can drive the sliding ring 78 to reset.

[0029] The support structure 6 includes a socket cover 61 sleeved on the plug-in member 8. The plug-in member 8 and the socket cover 61 are rotatably connected. A support rod 63 is fixedly connected to the bottom of the socket cover 61. The lower end of the support rod 63 is fixedly connected to a fixed seat 64, and the fixed seat 64 is fixed to the output end of the adjustment slide 3. During actual use, the output end of the adjustment slide 3 can adjust the position of the support rod 63 through the fixed seat 64, thereby realizing the position adjustment of the support tube 71 driven by the plug-in member 8 by the support structure 6, and the position adjustment of the pipeline member 5 on the plug-in member 8 can be realized.

[0030] The inner cavity of the socket cover 61 communicates with the inner cavity of the plug-in member 8. An exhaust pipe 62 is fixedly connected to the socket cover 61, and the inner cavity of the exhaust pipe 62 communicates with the inner cavity of the socket cover 61. The inner cavity of the exhaust pipe 62 communicates with the inner cavity of the plug-in member 8 through the socket cover 61. When the exhaust end of the exhaust pipe 62 is connected to an external air extraction device, the hot air and welding fumes inside the plug-in member 8 can be quickly discharged through the exhaust pipe 62.

[0031] A fixing ring 43 is fixedly connected to the socket cover 61. A blocking ring 45 is fixedly connected to the inner wall of the fixing ring 43, and an adjustment pipe 4 is fixedly connected to the fixing ring 43. The blocking ring 45 can block the inner cavity of the adjustment pipe 4, preventing the hot air and welding fumes in the inner cavity of the plug-in member 8 from entering the inside of the adjustment pipe 4, avoiding contact between the hot air and welding fumes and the screw member 42, and preventing excessive wear of the screw member 42 when the adjustment pipe 4 rotates.

[0032] A screw member 42 penetrates through the adjustment pipe 4. A fixing rod 44 and a rotating head 41 are fixedly connected to the screw member 42. An insertion pipe 82 is fixedly connected to the fixing rod 44. An insertion column 83 is inserted into the insertion pipe 82, and the insertion column 83 is fixedly connected inside the plug-in member 8. The fixing rod 44 and the insertion pipe 82 are inserted into the inside of the plug-in member 8, and magnetic blocks 81 are fixedly connected to the insertion pipe 82 and the fixing rod 44. When the rotating head 41 drives the screw member 42 to rotate on the adjusting pipe 4, the screw member 42 can drive the fixing rod 44 and adjust the use position of the insertion pipe 82. At this time, the insertion pipe 82 can be sleeved on the insertion column 83. It should be noted that when the insertion pipe 82 is sleeved on the insertion column 83, the air inside the insertion pipe 82 can be discharged through the gap between the insertion pipe 82 and the insertion column 83. When the insertion pipe 82 is sleeved on the insertion column 83, the insertion pipe 82 can drive the use position of the magnet block 81 to be adjusted. When the magnet block 81 approaches the magnetic head 711, the repulsive force generated by the magnet block 81 will drive the magnetic head 711 to move inside the sleeve pipe 74. At this time, the insertion rod 75 can drive the abutting head 73 to separate from the support pipe 71, and the abutting head 73 can clamp the pipe fitting 5, so that pipe fittings 5 with different diameters can be clamped on the support pipe 71. It should be noted that the inner diameter of the magnet block 81 is smaller than the inner diameter of the insertion member 8, so that the welding fume and hot air can penetrate inside the insertion member 8.

[0033] Embodiment 4: Please refer to Figures 2 - 8 As shown in the figure, based on Embodiment 2, the present invention provides a technical solution. Different from Embodiment 2, this embodiment can drive the pipe fitting 5 on the abutting head 73 to rotate slowly, which can avoid damage to the welding end of the pipe fitting 5 caused by centrifugal force; The transmission structure includes a transmission seat 14, which is fixedly connected to the insertion member 8 at a position close to the support structure 6. A first transmission disk 13 is fixedly connected to the transmission seat 14. A second transmission disk 15 is engaged with the first transmission disk 13. A transmission motor 10 is fixedly connected to the installation table 2 at a position close to the second transmission disk 15. The output end of the transmission motor 10 is fixedly connected to a speed reducer 9, and the output end of the speed reducer 9 is fixedly connected to the second transmission disk 15; During actual use, the output shaft of the transmission motor 10 can drive the second transmission disk 15 to rotate through the speed reducer 9. The second transmission disk 15 can drive the insertion member 8 to rotate through the first transmission disk 13. Since the insertion pipe 82 and the insertion column 83 are inserted, the insertion pipe 82 will not rotate synchronously during this process. At this time, the pipe fitting 5 on the insertion member 8 can rotate during welding, and the welding part of the pipe fitting 5 can be adjusted. Since the output shaft of the transmission motor 10 is connected to the speed reducer 9, this can prevent the output shaft of the transmission motor 10 from driving the insertion member 8 to rotate rapidly, avoid deformation of the welding end of the pipe fitting 5 under the action of centrifugal force, and thus improve the welding quality of the pipe fitting 5.

[0034] Working principle: During the actual use of the laser welding device, the staff first sleeved the pipe fitting 5 on the support pipe 71, and then rotated the screw member 42 through the rotating head 41. During the rotation of the screw member 42, the magnet block 81 can be driven to approach the magnetic head 711. Since the magnetic poles of the magnet block 81 and the magnetic head 711 repel each other, at this time, the magnetic head 711 will drive the abutting head 73 to abut against the pipe fitting 5 through the insertion rod 75, realizing the fixation of the pipe fitting 5 on the connector 8. Subsequently, the staff turns on the adjustment slide 3 to work. During this process, the first clamping head 11 and the second clamping head 12 can be clamped. At this time, the two connectors 8 can be assembled into an integral rod-shaped structure, enabling the welding parts of the two pipe fittings 5 to abut against each other, avoiding the asynchronous rotation of the welding parts of the two pipe fittings 5. Then, when the staff connects the exhaust end of the exhaust pipe 62 to an external air extraction device, the hot air and welding fumes inside the connector 8 can be quickly discharged through the exhaust pipe 62. At the same time, the staff turns on the drive motor 10 to work. The output end of the drive motor 10 can drive the first drive disk 13 to rotate through the second drive disk 15. At this time, the first drive disk 13 can drive the pipe fitting 5 to rotate and weld on the welding device 1 through the connector 8.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification is only the principle of the present invention.
