Description

Technical Field

[0001] This utility model belongs to the field of laser welding auxiliary equipment, specifically relating to a turbine fan welding fixture. Background Technology

[0002] A turbofan is a type of hydrodynamic machine that converts power into the kinetic energy of a fluid through rotating blades, thereby generating airflow. This device is widely used in aviation, automotive, air conditioning, ventilation systems, and other fields requiring airflow.

[0003] With increasing emphasis on energy conservation, emission reduction, and environmental protection in the aviation, automotive, and other industrial sectors, the design and manufacturing technologies of turbofans are constantly being optimized. The existing turbofan manufacturing process covers multiple stages from raw material preparation to the final product, including casting, rough machining, finish machining, heat treatment, and surface treatment. Specifically, when performing surface treatment on turbofans using finish machining techniques, the turbofan needs to be clamped in a fixture for laser processing.

[0004] Existing turbine fan fixtures are often immovable, requiring multiple starts and stops and adjustments to the laser welding head position during laser welding, as well as precise positioning of each fan blade's corresponding processing position for sequential processing. This makes the laser welding process extremely cumbersome. Furthermore, existing turbine fan fixtures often only clamp the turbine fan as a whole, neglecting the issue that the continuous impact of the laser during welding can cause the fan blades to bend downwards and deform, resulting in low overall quality of the produced turbine fans. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a turbine fan welding fixture to solve the problem of the cumbersome laser welding process caused by the immovable turbine fan fixture in the prior art, as well as the problem that it only clamps the turbine fan as a whole and ignores the problem that the fan blades may bend downward and deform during the laser welding process.

[0006] One aspect of this utility model provides a turbine fan welding fixture, including a fixture assembly, the fixture assembly being mounted on a processing table, the processing table being equipped with a laser assembly, the laser assembly being used to process a turbine fan, the turbine fan including a fan body and fan blades;

[0007] The clamp assembly includes:

[0008] Clamping components are used in conjunction with limiting components to control the stability of the fan blades during the welding process;

[0009] Limiting components are used to support and limit the fan body and blades, and to control the rotation of the fan body and blades.

[0010] It should be noted that both the clamping and limiting components are mounted on the processing table and are located below the laser assembly. The laser assembly includes an external laser welding device and a laser welding head mounted on the laser welding device. In actual use, the laser welding head can be controlled to move to the preset welding point during the welding process by directly setting the preset welding point of the laser welding device, thereby controlling the specific welding position according to the actual processing requirements.

[0011] It should be noted that in actual use, during the preparation process, the operator needs to load the turbine fan. At this time, the limiting and clamping components in the fixture assembly work together to ensure that the fan body and the fan blades are in contact, with the fan blades in the processing position. During the welding process, the laser welding head in the laser assembly starts working until the welding of a single fan blade is completed. Then, the operator controls the laser welding head to stop working and controls the clamping component to stop contacting the fan blade. The limiting component then controls the fan body and the fan blades to rotate together until the next unwelded fan blade is in the processing position. At this time, the operator again controls the clamping component to ensure that the fan body and the fan blades are in contact, and controls the laser welding head to work again until the welding of that fan blade is completed. Repeating the above operation completes the processing of the turbine fan.

[0012] In this solution, the rotation of the turbine fan on the fixture assembly can be controlled by the cooperation of the laser component and the fixture assembly. Therefore, during the processing, it is only necessary to control the rotation of the turbine fan on the fixture assembly and the operation of the laser component in sequence, repeating this process until all blades on the turbine fan are welded, which greatly simplifies the laser welding process. In addition, this utility model supports and limits the fan body and blades through the limiting component, which greatly reduces the downward bending and deformation of the blades during the processing, thereby improving the overall production quality of the turbine fan.

[0013] In one embodiment, the limiting component includes a support member and a rotating member, with the support member mounted on the rotating member.

[0014] It should be noted that the support component is used to provide support and limit the fan body and fan blades to enhance the stability of the fan body and fan blades in the subsequent laser welding process; the rotating component is used to control the movement of the next fan blade to the processing position for processing after the processing of a single fan blade is completed.

[0015] In one embodiment, the rotating component includes a rotating disk and a connecting component. The connecting component is mounted on the rotating disk, and the support component has a connecting hole. The connecting component connects the support component and the rotating disk through the connecting hole.

[0016] It should be noted that the connector can be a connecting rod, and the support can be installed onto the rotating disk through the connecting hole.

[0017] It should be noted that, in actual use, the rotating component 32 also includes a servo motor and a harmonic reducer, which are used to drive the rotating disk 321 to rotate.

[0018] In this solution, by opening connecting holes on the support and setting connecting parts on the rotating disk, the support can be made to rotate synchronously with the rotating disk, which makes it easier to control the movement of the fan blades to the processing position during the laser welding process.

[0019] In one embodiment, the support member includes a support base, the support base including a main body mounting groove and a fan blade mounting groove, the fan blade mounting groove surrounding the main body mounting groove.

[0020] In one embodiment, the fan blade mounting groove includes a plurality of spiral protrusions distributed around the main body mounting groove.

[0021] It should be noted that the shape of the spiral protrusion is adapted to the shape of the fan blade.

[0022] In this solution, the shape of the spiral protrusion is set to match the shape of the fan blade, and multiple spiral protrusions are distributed around the main body mounting groove. The spiral protrusions can support the fan blade and prevent the fan blade from bending downward and deforming during the laser welding process.

[0023] In one embodiment, the main body mounting groove has mounting holes.

[0024] It should be noted that the fan body also includes a mounting rod located at the bottom of the fan body. The size of the mounting hole is adapted to the mounting rod, and the mounting hole is used to limit the mounting rod so as to limit the fan body.

[0025] In this solution, by opening mounting holes in the main mounting slot, the main mounting slot can limit the fan body, and the cooperation between the mounting holes and the mounting rod can further enhance the limiting strength of the main mounting slot on the fan body.

[0026] In one embodiment, the spiral protrusion has a groove, and a magnet is disposed inside the groove.

[0027] It should be noted that both the fan body and the fan blades are made of metal.

[0028] In this solution, by creating grooves on the spiral protrusions and placing magnets inside the grooves, the connection strength between the fan blades and the spiral protrusions can be enhanced by the magnetic attraction between the magnets and the metal material. This improves the stability of the fan blades during the welding process and reduces the possibility of displacement of the fan blades under laser welding.

[0029] In one embodiment, the clamping component includes a movable seat and a reinforcing member, the reinforcing member being movably connected to the movable seat.

[0030] It should be noted that the movable base is equipped with a driver device for driving the reinforcement components.

[0031] In one embodiment, the reinforcement includes a driver and an output component. The driver is used to drive the output component to extend or retract in the horizontal direction, and the side of the output component away from the driver is adapted to the fan blade.

[0032] It should be noted that the reinforcement component can be a cylinder, the driving component can be the cylinder body, and the output component can be the cylinder output end.

[0033] In this solution, by setting up a movable seat and reinforcement components, and adapting the fan blades to the side of the output component away from the drive component, the fan blades located at the processing position can be further reinforced by the reinforcement components after the fan body and fan blades are loaded, so as to further enhance the stability of the fan blades during the welding process.

[0034] In one embodiment, a welding base and a laser base are also mounted on the processing table. The fixture assembly is mounted on the processing table via the welding base, and the laser assembly is mounted on the processing table via the laser base.

[0035] It should be noted that the welding base is equipped with a rotation drive device for controlling the rotation of the fan body and fan blades by driving and limiting components, and the laser base is equipped with a power supply device for supplying power to the laser welding head.

[0048] Please refer to Figure 1-7 In one embodiment, a turbine fan welding fixture is provided, including a fixture assembly 2, which is mounted on a processing table 1. A laser assembly 5 is mounted on the processing table 1. The laser assembly 5 is used to process a turbine fan 6, which includes a fan body 61 and fan blades 62.

[0049] The clamp assembly 2 includes:

[0050] Clamping component 4 is used in conjunction with limiting component 3 to control the stability of fan blade 62 during the welding process;

The laser assembly 5 includes an external laser welding device and a laser welding head installed on the laser welding device. In actual use, the laser welding head can be controlled to move to the preset welding point for welding during the welding process by directly setting the preset welding point of the laser welding device, thereby controlling the specific welding position according to the actual processing requirements.

[0053] It should be noted that in actual use, during the preparation process, the operator needs to load the turbine fan 6. At this time, the limiting component 3 and the clamping component 4 in the fixture assembly 2 work together to make the fan body 61 and the fan blade 62 in a contact state, with the fan blade 62 in the processing position. When the welding process is underway, the laser welding head in the laser assembly 5 starts working until the welding of a single fan blade 62 is completed. Then, the operator controls the laser welding head to stop working and controls the clamping component 4 to stop contacting the fan blade 62. The limiting component 3 then controls the fan body 61 and the fan blade 62 to rotate together until the next unwelded fan blade 62 is in the processing position. At this time, the operator controls the clamping component 4 again to make the fan body 61 and the fan blade 62 in a contact state and controls the laser welding head to work again until the welding of the fan blade 62 is completed. Repeating the above operation will complete the processing of the turbine fan 6.

[0054] In this embodiment, the cooperation of the laser component 5 and the fixture component 2 enables the turbine fan 6 to rotate on the fixture component 2. Thus, during the processing, it is only necessary to control the rotation of the turbine fan 6 on the fixture component 2 and the operation of the laser component 5 in sequence, repeating this process until all blades on the turbine fan 6 are welded, which greatly simplifies the laser welding process. In addition, the present invention supports and limits the fan body 61 and the fan blades 62 through the limiting component 3, which greatly reduces the downward bending and deformation of the fan blades 62 during the processing, thereby improving the overall production quality of the turbine fan 6.
