Description

Technical Field

[0001] This invention belongs to the field of brazing equipment, and particularly relates to a brazing equipment for a gas turbine sector section. Background Technology

[0002] Before brazing the gas turbine sector section, the stator blades and blade profiles are first assembled and fixed by spot welding. Then, different amounts of brazing paste are applied to the brazing joint between the stator blades and blade profiles according to processing requirements, and then the section is placed in a vacuum brazing furnace for brazing. However, existing brazing equipment has the following disadvantages:

[0003] During the application of brazing filler metal, it is impossible to guarantee that the coating area is free of water stains, oil stains, and other impurities. This results in insufficient separation of the brazing filler metal from the workpiece, affecting the brazing quality. Furthermore, it is impossible to adjust the amount of coating material at different locations according to processing requirements, and the cleaning area cannot be dynamically adjusted based on the amount of coating material, leading to a lack of quality assurance in the application of brazing filler metal. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a brazing equipment for gas turbine sector sections. This equipment utilizes a multi-degree-of-freedom robotic arm to enable a cleaning and coating component to accurately and stably clean and coat the brazed joints of the workpiece. A spherical elastic cleaning felt cleans the brazed joints while simultaneously providing contour positioning, ensuring sufficient contact between the solder and the workpiece while preventing vibration from affecting the coating position. Furthermore, increasing the injection pressure to increase the coating volume simultaneously expands the elastic inner liner and the elastic cleaning felt, thereby increasing the contact area between the elastic cleaning felt and the workpiece. This ensures that the solder remains in full contact with the workpiece without impurities. A solenoid valve controls the opening and closing of the coating process, preventing excess solder from falling onto the workpiece surface after coating and forming slag on the workpiece surface after processing in a vacuum brazing furnace.

[0005] The objective of this invention can be achieved through the following technical solution: A brazing equipment for a gas turbine fan-shaped section, comprising a base plate, characterized in that two sets of clamps are symmetrically and fixedly connected on the upper side of the base plate in an arc direction, and a lower blade plate and an upper blade plate are clamped and fixed between the two sets of clamps. Multiple stator blades are uniformly distributed and fixedly connected between the lower blade plate and the upper blade plate in the arc direction of the upper blade plate. Each stator blade is pre-fixed to the lower blade plate and the upper blade plate by spot welding. An arc-shaped sliding groove plate is fixedly connected to the upper side of the base plate away from the upper blade plate. A sliding seat is slidably connected within the arc-shaped sliding groove plate. Multiple degrees of freedom robotic arms are rotatably connected to the upper side of the sliding seat outside the arc-shaped sliding groove plate. A cleaning coating component for cleaning the weld joint and applying paste-like brazing filler is fixedly connected to the rotating end of the robotic arm away from the sliding seat. This allows the cleaning coating component to move flexibly and accurately at the brazing joint between workpieces, ensuring the stability and accuracy of the coating.

[0006] Preferably, the coating component includes a fixed rod, which is fixedly connected to the rotating end of the robotic arm away from the sliding seat. A first fixed seat is fixedly connected to the end of the fixed rod away from the robotic arm. A dryer is fixedly connected to the end of the first fixed seat near the base plate. The dryer and the first fixed seat are fastened together by multiple screws. A second shaft seat is fixedly connected to the side of the dryer near the robotic arm. A first shaft seat is fixedly connected to the side of the dryer away from the robotic arm. The dryer is fastened to the second shaft seat and the gearbox by multiple screws. Second fixed seats are symmetrically distributed and rotatably connected to the ends of the first and second shaft seats away from the first fixed seat. A hollow, spherical, elastic inner liner is fixedly connected between the two second fixed seats. A spherical, elastic cleaning felt, fixedly connected to the two second fixed seats, is fixedly connected to the outside of the elastic inner liner. This allows for cleaning of the brazed joints while coating, ensuring sufficient contact between the brazing material and the workpiece, and guaranteeing brazing quality.

[0007] Preferably, a hollow second shaft is fixedly connected to the center of the second fixed seat inside the first shaft seat, and a hollow first shaft coaxial with the second hollow shaft is fixedly connected to the center of the second fixed seat inside the second shaft seat. The two ends of the first hollow shaft and the second hollow shaft extending into the elastic inner liner are fixedly connected. A transmission shaft is rotatably connected to the side of the first fixed seat near the robotic arm, located below the first fixed seat. A gear box is drively connected to the end of the transmission shaft away from the first fixed seat and fixedly connected to the rotating end of the robotic arm away from the sliding seat. A motor is fixedly connected to the side of the gear box away from the fixed rod. The power output end of the motor is drively connected to the gear box. A driven wheel is fixedly connected to the circumferential surface of the end of the first hollow shaft extending out of the second fixed seat. A driving wheel is fixedly connected to the transmission shaft at the corresponding position of the driven wheel. A synchronous belt meshes and drives between the driving wheel and the driven wheel.

[0008] Preferably, multiple through grooves are evenly distributed on the circumferential surfaces of the first and second hollow shafts located within the elastic inner liner. A sliding groove is formed on the side of the first shaft seat away from the second shaft seat. A hollow paint head is slidably connected within the sliding groove. A communication port communicating with the opening of the second hollow shaft is formed on the upper side of the paint head near the second hollow shaft. A paint port communicating with the hollow interior of the paint head is formed at the lower end of the paint head. A solenoid valve is fixedly connected to the upper side of the first shaft seat at the corresponding position of the sliding groove. A telescopic rod that extends into the sliding groove and is slidably connected to the first shaft seat is slidably driven within the solenoid valve. The end of the telescopic rod away from the solenoid valve is fixedly connected to the paint head. A spring surrounding the outside of the telescopic rod is fixedly connected between the side of the paint head near the solenoid valve and the top side of the sliding groove. After the solenoid valve controls the paint head to close, the remaining brazing material inside the paint head will no longer be discharged from the paint outlet under its own tension. This avoids excess brazing material dripping from the paint outlet and adhering to the workpiece surface after the coating work is completed, which would cause slag to be generated on the workpiece surface after the workpiece enters the vacuum brazing furnace for brazing.

[0009] Preferably, the dryer has an air cavity inside, and a brush layer with gaps is fixedly connected to the side of the dryer near the elastic cleaning felt. Multiple air grooves communicating with the air cavity are evenly distributed on the side of the dryer near the elastic cleaning felt. Two connectors communicating with the air cavity are symmetrically distributed and fixedly connected on opposite sides of the dryer.

[0010] Preferably, a feeder for supplying solder paste is fixedly connected to one corner of the upper side of the base plate, and the feeder is connected to one end of the first hollow shaft extending out of the driven wheel via a hose.

[0011] Preferably, a hot air blower for supplying drying hot air is fixedly connected to the upper side of the feeder, and the air inlet and outlet of the hot air blower are respectively connected to two connectors through flexible hoses.

[0012] Compared with existing technologies, this brazing equipment for gas turbine sector sections has the following advantages:

[0013] A multi-degree-of-freedom robotic arm enables the cleaning and coating component to accurately and stably clean and coat the brazed joints of the workpiece. A spherical elastic cleaning felt cleans the brazed joints while also serving as a contour positioning device. This ensures full contact between the solder and the workpiece, while preventing the coating position from being affected by vibration. Simultaneously, increasing the injection pressure to increase the coating volume causes the elastic inner liner and elastic cleaning felt to expand, thereby increasing the contact area between the elastic cleaning felt and the workpiece. This ensures that the solder always has full contact with the workpiece without impurities. A solenoid valve controls the opening and closing of the coating process, preventing excess solder from falling onto the workpiece surface after coating and forming slag on the workpiece surface after processing in a vacuum brazing furnace.

Detailed Implementation

[0023] The core of this invention is to provide a brazing device for a gas turbine sector segment. Compared with the prior art, it can apply a paste-like brazing material to the welding area of ​​the gas turbine sector segment while simultaneously cleaning the welding area with an elastic cleaning felt, ensuring the coating and welding effects. By increasing the coating amount, the elastic inner liner and the elastic cleaning felt expand to increase the cleaning area, thereby ensuring that the cleaning area and the coating area are consistent.

[0024] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1:

[0027] like Figure 1 , Figure 3 , Figure 6 and Figure 7As shown, a brazing equipment for a gas turbine fan-shaped section includes a base plate 10. Two sets of clamps 11 are symmetrically distributed and fixedly connected on the upper side of the base plate 10 in an arc direction. A lower blade plate 12 and an upper blade plate 14 are clamped and fixed between the two sets of clamps 11. Multiple stator blades 13 are evenly distributed and fixedly connected between the lower blade plate 12 and the upper blade plate 14 in the arc direction of the upper blade plate 14. Each stator blade 13 is pre-fixed to the lower blade plate 12 and the upper blade plate 14 by spot welding. An arc-shaped slide plate 19 is fixedly connected to the upper side of the base plate 10 away from the upper blade plate 14. A sliding seat 15 is slidably connected inside the arc-shaped slide plate 19. A robotic arm 16 with multiple degrees of freedom is rotatably connected to the upper side of the sliding seat 15 outside the arc-shaped slide plate 19. A cleaning coating component for cleaning the welding area and applying paste brazing material is fixedly connected to the rotating end of the robotic arm 16 away from the sliding seat 15.

[0028] like Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the coating component includes a fixing rod 20, which is fixedly connected to the rotating end of the robotic arm 16 away from the sliding seat 15. A first fixing seat 22 is fixedly connected to the end of the fixing rod 20 away from the robotic arm 16. A dryer 27 is fixedly connected to the end of the first fixing seat 22 near the base plate 10. The dryer 27 and the first fixing seat 22 are fastened together by multiple screws 39. A second bearing seat 34 is fixedly connected to the side of the dryer 27 near the robotic arm 16. A first bearing seat 28 is fixedly connected to the side of the dryer 27 away from the robotic arm 16. The dryer 27 is fastened together with the second bearing seat 34 and the gear box 38 by multiple screws 39 respectively. Second fixing seats 43 are symmetrically distributed and rotatably connected to the two ends of the first bearing seat 28 and the second bearing seat 34 away from the first fixing seat 22. A hollow spherical elastic inner liner 42 is fixedly connected between the two second fixing seats 43. A spherical elastic cleaning felt 35, which is fixedly connected to the two second fixing seats 43, is fixedly connected to the outside of the elastic inner liner 42.

[0029] like Figure 2 , Figure 4 and Figure 8As shown, a hollow second hollow shaft 46 is fixedly connected to the center of the second fixed seat 43 inside the first shaft seat 28. A hollow first hollow shaft 45, coaxial with the second hollow shaft 46, is fixedly connected to the center of the second fixed seat 43 inside the second shaft seat 34. The two ends of the first hollow shaft 45 and the second hollow shaft 46 are fixedly connected inside the elastic inner liner 42. A drive shaft 21 is rotatably connected to the side of the first fixed seat 22 near the robotic arm 16, located on the lower side of the first fixed seat 22. The drive shaft 21 is located away from the first fixed seat 22. A gearbox 38 is fixedly connected to the rotating end of the robotic arm 16 away from the sliding seat 15. A motor 37 is fixedly connected to the side of the gearbox 38 away from the fixed rod 20. The power output end of the motor 37 is connected to the gearbox 38. A driven wheel 25 is fixedly connected to the circumferential surface of the first hollow shaft 45 that extends out of the second fixed seat 43. A driving wheel 23 is fixedly connected to the transmission shaft 21 at the corresponding position of the driven wheel 25. A synchronous belt 24 meshes and drives the driving wheel 23 and the driven wheel 25.

[0030] like Figure 4 and Figure 8 As shown, multiple through slots 47 are evenly distributed on the two circumferential surfaces of the first hollow shaft 45 and the second hollow shaft 46 within the elastic inner liner 42. A sliding groove 29 is provided on the side of the first shaft seat 28 away from the second shaft seat 34. A hollow paint head 32 is slidably connected within the sliding groove 29. A connecting port 48 is provided on the upper side of the paint head 32 near the second hollow shaft 46, communicating with the opening of the second hollow shaft 46. A paint port 44 is provided at the lower end of the paint head 32, communicating with the hollow interior of the paint head 32. A solenoid valve 33 is fixedly connected to the upper side of the first shaft seat 28 at the corresponding position of the sliding groove 29. A telescopic rod 31 is slidably connected within the solenoid valve 33, extending into the sliding groove 29 and slidably connected to the first shaft seat 28. The end of the telescopic rod 31 away from the solenoid valve 33 is fixedly connected to the paint head 32. A spring 30 is fixedly connected between the side of the paint head 32 near the solenoid valve 33 and the top side of the sliding groove 29, surrounding the outside of the telescopic rod 31.

[0031] In this embodiment, the operator fixes the lower blade plate 12, stator blade 13, and upper blade plate 14, which are pre-fixed by electric welding, onto the fixture 11. Then, the system controls the robotic arm 16 to move the cleaning coating component along the weld between the stator blade 13 and the lower blade plate 12 and the upper blade plate 14, ensuring that the elastic cleaning felt 35 is located at the front end of the movement direction and the coating head 32 is located at the rear end of the movement direction. During the movement, the elastic cleaning felt 35 remains in contact with the workpiece and plays a conforming role, ensuring that the relative position between the coating head 32 and the workpiece is stable and preventing vibration from causing the coating head 32 to shift and misalign, resulting in misaligned coating.

[0032] While moving, the motor 37 drives the transmission shaft 21 to rotate, thereby causing the drive wheel 23 to drive the driven wheel 25 to rotate through the synchronous belt 24, which in turn causes the elastic inner liner 42 to rotate. The elastic cleaning felt 35 on the surface of the elastic inner liner 42 is used to clean water stains, dust and oil stains at the weld, ensuring that the solder is in full contact with the workpiece surface.

[0033] While moving, brazing material is injected into the first hollow shaft 45. The brazing material enters the elastic inner liner 42 from the through groove 47 and fills the elastic inner liner 42, so that the elastic inner liner 42 can fit the gap when it is squeezed and deformed during the cleaning of the welded area, thus ensuring the cleaning quality.

[0034] Then, the brazing material enters the second hollow shaft 46 from the elastic inner liner 42 through the through groove 47 on the second hollow shaft 46, and is squeezed into the coating head 32 through the connecting port 48 and finally discharged from the coating port 44 to be applied to the weld.

[0035] After the brazing filler is applied, the solenoid valve 33 is controlled to immediately raise the coating head 32, thereby disconnecting the connection between the connecting port 48 and the second hollow shaft 46. This prevents the brazing filler from entering the coating head 32, and the remaining brazing filler in the coating head 32 will no longer be discharged from the coating port 44 under its own tension. This avoids excess brazing filler dripping from the coating port 44 and adhering to the workpiece surface after the coating is applied, which would cause slag to form on the workpiece surface after the workpiece enters the vacuum brazing furnace for brazing.

[0036] Example 2:

[0037] As a further embodiment, such as Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, multiple through slots 47 are evenly distributed on the two circumferential surfaces of the first hollow shaft 45 and the second hollow shaft 46 within the elastic inner liner 42. A sliding groove 29 is provided on the side of the first shaft seat 28 away from the second shaft seat 34. A hollow paint head 32 is slidably connected within the sliding groove 29. A connecting port 48 is provided on the upper side of the paint head 32 near the second hollow shaft 46, communicating with the opening of the second hollow shaft 46. A paint port 44 is provided at the lower end of the paint head 32, communicating with the hollow interior of the paint head 32. A solenoid valve 33 is fixedly connected to the upper side of the first shaft seat 28 at the corresponding position of the sliding groove 29. A telescopic rod 31 is slidably connected within the solenoid valve 33, extending into the sliding groove 29 and slidably connected to the first shaft seat 28. The end of the telescopic rod 31 away from the solenoid valve 33 is fixedly connected to the paint head 32. A spring 30 is fixedly connected between the side of the paint head 32 near the solenoid valve 33 and the top side of the sliding groove 29, surrounding the outside of the telescopic rod 31.

[0038] like Figure 6 and Figure 8As shown, the dryer 27 has an air cavity 36 inside. A brush layer 41 with gaps is fixedly connected to the side of the dryer 27 near the elastic cleaning felt 35. Multiple air grooves 40 communicating with the air cavity 36 are evenly distributed on the side of the dryer 27 near the elastic cleaning felt 35. Two connectors 26 communicating with the air cavity 36 are symmetrically distributed and fixedly connected on opposite sides of the dryer 27.

[0039] like Figure 1 , Figure 6 and Figure 8 As shown, a feeder 17 for supplying solder paste is fixedly connected to one corner of the upper side of the base plate 10. The feeder 17 is connected to one end of the first hollow shaft 45 extending out of the driven wheel 25 via a hose. A hot air blower 18 for supplying dry hot air is fixedly connected to the upper side of the feeder 17. The air inlet and outlet of the hot air blower 18 are respectively connected to two connectors 26 via hoses.

[0040] In this embodiment, according to the processing requirements, when applying the coating to the brazing connection between the blade and the bore of the gas turbine sector section, more brazing material needs to be applied to the exhaust side of the blade and less to the intake side. The feeder 17 is controlled to increase the pressure of the brazing material injected into the first hollow shaft 45, thereby increasing the amount of brazing material discharged from the coating port 44, or decreasing the pressure to reduce the amount of brazing material discharged, thus changing the amount of coating.

[0041] As the coating amount changes, the area covered by the brazing material adhering to the brazed joint of the workpiece increases. Consequently, the cleaning area of ​​the elastic cleaning felt 35 in the direction of movement increases. When the pressure of the brazing material injected into the first hollow shaft 45 increases, the elastic inner liner 42 is stretched due to the increased internal pressure, and the elastic cleaning felt 35 is stretched open accordingly. When the movement trajectory of the cleaning coating component controlled by the robotic arm 16 remains unchanged, the stretching of the elastic cleaning felt 35 increases the contact area between the elastic cleaning felt 35 and the workpiece at the brazed joint. Conversely, when the injection pressure decreases, the elastic cleaning felt 35 retracts under its own elasticity, and the cleaning area decreases. This ensures that the cleaning coverage of the elastic cleaning felt 35 remains consistent with the brazing material coverage, guaranteeing sufficient contact between the brazing material and the workpiece.

[0042] During the cleaning process of the elastic cleaning felt 35 at the brazed joint of the workpiece, it continuously comes into contact with the brush layer 41. The dust adhering to the elastic cleaning felt 35 is brushed off by the brush layer 41. The hot air blower 18 continuously injects unidirectional dry hot air into the dryer 27, generating low pressure at the air groove 40. The dust enters the air groove 40 from the gaps between the bristles of the brush layer 41 and is carried away by the dry hot air, thereby achieving the effect of cleaning the elastic cleaning felt 35 and ensuring that the elastic cleaning felt 35 maintains a high-quality cleaning effect at the brazed joint. At the same time, the dry hot airflow carries away the water stains adhering to the elastic cleaning felt 35, ensuring the dryness of the elastic cleaning felt 35 and ensuring its water absorption effect.

[0043] The above description is merely an embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of the present invention.
