Description

Technical Field

[0001] This invention relates to the field of turbine disk assembly equipment, and in particular to a positioning and flaring device for an integral turbine disk damping pin. Background Technology

[0002] The integral turbine disk is a key rotor component in aero engines used for power transmission. Turbine blades (such as...) are directly fixed to the turbine disk in an integral turbine disk. Figure 1 As shown, an adjustment gap is provided between the two turbine blades on the integral turbine disk. A damping hole is located at the end of the adjustment gap. To improve the damping effect of the integral turbine disk, a damping pin is installed in the damping hole. The damping pin is a hollow tube with a clearance fit between its outer wall and the inner wall of the damping hole. To fix the damping pin to the damping hole, both ends of the damping pin are enlarged so that neither end can pass through the damping hole. The existing processing method involves first enlarging one end of the damping pin, then inserting the damping pin into the damping hole, and then enlarging the other end of the damping pin. Because the integral turbine disk is a high-precision component, each enlarging operation requires precise control, resulting in a slow enlarging speed. Summary of the Invention

Detailed Implementation

[0015] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. 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.

[0016] See Figures 2-7 The present invention provides a technical solution: A positioning and flaring device for an integral turbine disk damping pin includes a base 1, an isometric rotation assembly, a flaring drive assembly, an upper flaring assembly, and a lower flaring assembly. All three flaring assemblies are fixedly mounted on the base 1. The turbine disk 2 is mounted on the isometric rotation assembly. The lower flaring assembly engages with the lower end of the damping pin 3 on the turbine disk 2, and the upper flaring assembly engages with the upper end of the damping pin 3 on the turbine disk 2. Both the upper and lower flaring assemblies are connected to the flaring drive assembly. The base 1 is used to mount the isometric rotation assembly, the flaring drive assembly, the upper flaring assembly, and the lower flaring assembly. The flaring drive assembly drives the upper and lower flaring assemblies. The isometric rotation assembly rotates the turbine disk 2, ensuring that the turbine disk 2 rotates at the same angle each time, meaning that the damping hole on the turbine disk 2 is always directly above the lower flaring assembly after each rotation. The entire working process is as follows: the isoangular rotation component drives the turbine disk 2 to rotate together, so that the damping hole on the turbine disk 2 is directly above the lower flaring component. Then, the flaring drive component drives the lower flaring terminal 22 on the lower flaring component to move upward. When the lower flaring terminal 22 moves to the preset position, it stops. At this time, the damping pin 3 is inserted into the damping hole, ensuring that the lower end of the damping pin 3 is inserted into the lower flaring terminal 22. Then, the flaring drive component controls the upper flaring component to move downward, and the upper flaring terminal 33 on the upper flaring component is inserted into the damping hole. Inside the upper end of the shock absorber pin 3, the upper flaring assembly is further controlled to work. The lower flaring terminal 22 and the upper flaring terminal 33 work together to flare both ends of the shock absorber pin 3. After the flaring is completed, the lower flaring terminal 22 is driven to move downward by the flaring drive assembly, and the upper flaring terminal 33 is also driven to move upward. After the lower flaring terminal 22 and the upper flaring terminal 33 move to their initial positions, the turbine disk 2 is controlled to rotate at a fixed angle by the equal angle rotation assembly, so that the next shock absorber hole on the turbine disk 2 is directly above the lower flaring assembly.

[0017] In some embodiments, the reaming drive assembly includes a pressure pipe 4, a plug plate 5, an inflow plug 6, an outflow plug 7, and a drive component. The pressure pipe 4 is mounted on the base 1, and its pressure end is sealed and connected to the upper reaming assembly. The drive component is mounted on the drive end of the pressure pipe 4. A connection port 8 communicating with the interior of the pressure pipe 4 is provided in the middle of the pressure pipe 4, and the connection port 8 is sealed and connected to the lower reaming assembly. The plug plate 5 is sealed and fixedly mounted on the inner wall of the pressure pipe 4 and is positioned between the pressure end and the connection port 8. The plug plate 5 is provided with an inlet channel 9 and an outlet channel 10 with a tapered cross-section. An inflow plug 6 is provided on the inlet channel 9 and is sealed and fitted with the inlet channel 9. A high-pressure spring 11 is provided between the inflow plug 6 and the pressure end. An outflow plug 7 is provided on the outlet channel 10 and is sealed and fitted with the outlet channel 10. A low-pressure spring 12 is provided between the outflow plug 7 and the drive end. A control groove 42 is provided inside the base 1, and the reaming drive assembly is mounted inside the control groove 42. The connection port 8 is sealed and connected to the lower drive chamber 28 in the lower flaring assembly via a first hydraulic pipe, and the pressure end of the pressure pipe 4 is sealed and connected to the upper drive chamber 35 in the upper flaring assembly via a second hydraulic pipe. Both the upper and lower flaring assemblies are driven by hydraulic oil. A hydraulic oil chamber 43 is provided between the plug plate 5 in the pressure pipe 4 and the push plate 14 in the drive component. When the lower flaring terminal 22 and the upper flaring terminal 33 return to their initial positions, the hydraulic oil in the lower drive chamber 28 and the upper drive chamber 35 returns to the hydraulic oil chamber 43. During operation, the hydraulic oil in the hydraulic oil chamber 43 is first pressed into the lower drive chamber 28 under the action of the drive component, and then pressed into the upper drive chamber 35. The plug plate 5 is sealed and fixed inside the pressure pipe 4 and is perpendicular to the center line of the pressure pipe 4. The inlet channel 9 is located in the middle of the plug plate 5, and the outlet channel 10 is located on the edge of the plug plate 5. The diameter of the inlet channel 9 is larger than the diameter of the outlet channel 10. At the same time, the elastic force of the high pressure spring 11 is greater than the elastic force of the low pressure spring 12. In this technology, there are multiple outlet channels 10. A high-pressure bearing ring 44 and a low-pressure bearing ring 45 are provided on the inner wall of the pressure pipe 4. The high-pressure bearing ring 44 and the low-pressure bearing ring 45 are respectively connected to the pressure pipe 4 by threads. One end of the high-pressure spring 11 rests on the inflow plug 6 and the other end rests on the high-pressure bearing ring 44. The high-pressure bearing ring 44 is fixed on the pressure end, and the pressure pipe 4, the inflow plug 6, and the high-pressure spring 11 are arranged coaxially. One end of the low-pressure spring 12 rests on the outflow plug 7, and the other end of the low-pressure spring 12 rests on the low-pressure bearing ring 45. The low-pressure spring 12 and the outflow plug 7 are arranged coaxially. The low-pressure bearing ring 45 is located on the drive end side of the pressure pipe 4. Both the inflow plug 6 and the outflow plug 7 are conical plugs. The inflow plug 6 is provided with a high-pressure anti-slip protrusion that cooperates with the high-pressure spring 11, and the outflow plug 7 is also provided with a low-pressure anti-slip protrusion that cooperates with the low-pressure spring 12.Both the inflow plug 6 and the outflow plug 7 have annular grooves on their outer walls, and sealing rings are installed in the annular grooves. The sealing ring on the inflow plug 6 seals against the inner wall of the inflow channel 9, and the sealing ring on the outflow plug 7 seals against the inner wall of the discharge channel 10. The push plate 14 in the drive component will not contact the low-pressure bearing ring 45. The expansion drive assembly is screwed into the control groove 42 to make the entire structure more compact, while the base 1 protects the expansion drive assembly.

[0018] In some embodiments, the driving component includes a drive motor 13, a push plate 14, a rotating rod 15, and a push sleeve 16. The drive motor 13 is fixedly mounted on the end of the pressure tube 4, the push sleeve 16 is slidably mounted inside the pressure tube 4, the push plate 14 is mounted on the end of the push sleeve 16 and is sealed to the inner wall of the pressure tube 4, the rotating rod 15 is fixedly mounted on the end of the drive motor 13 and is threaded to the inner wall of the push sleeve 16, an anti-rotation protrusion 17 is provided on the inner wall of the pressure tube 4, and an anti-rotation groove 18 that cooperates with the anti-rotation protrusion 17 is provided on the outer wall of the push sleeve 16. The push plate 14 has an annular sealing groove on its outer wall, and a sealing ring is provided in the annular sealing groove. The sealing ring is sealed with the inner wall of the pressure pipe 4. The push plate 14 is driven to move by the push sleeve 16, and the push sleeve 16 is driven to move by the rotating rod 15. The outer wall of the rotating rod 15 is threaded with the inner wall of the push sleeve 16. The anti-rotation protrusion 17 is fixedly provided on the inner wall of the pressure pipe 4. The function of the anti-rotation protrusion 17 is to prevent the push sleeve 16 from rotating. Therefore, when the rotating rod 15 rotates, the push sleeve 16 can only push the push plate 14 to move. The drive motor 13 is a motor in the prior art. The function of the drive motor 13 is to drive the rotating rod 15 to rotate.

[0019] The working process of the reaming drive assembly is as follows: the drive motor 13 drives the rotating rod 15 to rotate forward. The rotating rod 15 compresses the hydraulic oil chamber 43 by pushing the sleeve 16 and the push plate 14. The hydraulic oil in the hydraulic oil chamber 43 first enters the lower drive chamber 28 through the first hydraulic pipe, thereby driving the lower reaming terminal 22 in the lower reaming assembly to move upward. When the lower reaming terminal 22 can no longer move, the push plate 14 continues to apply pressure to the hydraulic oil chamber 43, and the hydraulic oil in the hydraulic oil chamber 43 flows into the plug 6 and pushes it open. The hydraulic oil enters the upper drive chamber 35 through the inlet channel 9 and the second hydraulic pipe. The upper reaming assembly works to drive the upper reaming terminal 33 to move downward, and then the lower reaming terminal 22 moves upward. The two ends of the shock absorber pin 3 are opened by the action of the hole terminal 22 and the upper flaring terminal 33. After the two ends of the shock absorber pin 3 are processed, the drive motor 13 drives the rotating rod 15 to rotate in the opposite direction. Then, under the action of the push sleeve 16 and the push plate 14, the space of the hydraulic oil chamber 43 is increased. First, the hydraulic oil in the lower drive chamber 28 returns to the hydraulic oil chamber 43 through the first hydraulic pipe. When the lower flaring terminal 22 in the lower flaring assembly stops moving, the hydraulic oil chamber 43 further increases, causing the outlet plug 7 to open. At this time, the hydraulic oil in the upper drive chamber 35 enters the hydraulic oil chamber 43 through the second hydraulic pipe and the discharge channel 10. During this process, the upper flaring terminal 33 moves upward. This process completes the processing of the two ends of a shock absorber pin 3.

[0020] In some embodiments, the lower flaring assembly includes a lower flaring seat 19, a lower flaring sleeve 20, a lower flaring telescopic rod 21, and a lower flaring terminal 22.

The lower flaring seat 19 is fixed to the base 1 with screws. The lower flaring seat 19 is used to install the lower flaring sleeve 20. An adjusting rod 24 is provided to adjust the vertical position of the lower flaring sleeve 20. The lower flaring terminal 22 is mounted on the lower flaring telescopic rod 21, which is located inside the lower flaring sleeve 20, thus adjusting the vertical position of the lower flaring terminal 22. The lower flaring terminal 22 not only needs to flare the lower end of the shock absorber pin 3 but also needs to position the shock absorber pin 3 vertically. The lower flaring sleeve 20 is fixed in the adjusting hole 23 with a first screw 46, and the lower flaring terminal 22 is fixed in the lower end slot 27 with a second screw 47. Since the lower flaring terminal 22 may wear during use, it can be directly removed from the lower flaring telescopic rod 21 and replaced after wear. The partition plate 26 is sealed and fixed on the inner wall of the middle part of the lower expansion sleeve 20. A sealing groove is provided on the outer wall of the lower expansion telescopic rod 21. A sealing ring that seals with the inner wall of the lower expansion sleeve 20 is provided in the sealing groove. A step is provided on the middle part of the lower drive cavity 28. The step is provided to prevent the lower expansion telescopic rod 21 from contacting the partition plate 26 and to prevent subsequent hydraulic oil from entering the lower drive cavity 28. A limiting ring 48 is fixedly provided at the upper end of the lower expansion sleeve 20 to prevent the lower expansion telescopic rod 21 from separating from the lower expansion sleeve 20.

[0021] In some embodiments, the upper flaring assembly includes an upper flaring connector 29, an upper adjusting seat 30, an upper flaring sleeve 31, an upper flaring telescopic rod 32, and an upper flaring terminal 33.

An upper driving cavity 35 is provided between the upper adjusting seat 30 and the upper flaring telescopic rod 32, and the upper driving cavity 35 is sealed and connected to the pressure end. The upper end of the shock absorber pin 3 cooperates with the upper flaring terminal 33. The upper expanding hole connecting seat 29 is fixed to the base 1 with screws. The upper expanding hole connecting seat 29 has a mounting groove, and the upper adjusting seat 30 is fixed inside the mounting groove. The upper adjusting seat 30 adjusts the vertical position of the upper expanding hole sleeve 31. The upper expanding hole connecting seat 29 has an adjusting hole 49 that mates with the upper expanding hole sleeve 31. The adjusting hole 49 allows for fine adjustment of the position of the upper expanding hole sleeve 31. The inner wall of the adjusting hole 49 and the outer wall of the upper expanding hole sleeve 31 can be finely adjusted by inserting a thin plate to ensure that the lower expanding hole sleeve 20 and the upper expanding hole sleeve 31 are coaxially aligned. This prevents damage to the shock-absorbing pin 3 due to uneven force when the lower expanding hole terminal 22 and the upper expanding hole terminal 33 expand holes simultaneously. A stepped ring is provided inside the upper driving cavity 35 to prevent the upper end of the upper expanding hole telescopic rod 32 from contacting the upper adjusting seat 30. A sealing groove is provided on the outer wall of the upper expanding hole telescopic rod 32, and a sealing ring that seals with the inner wall of the upper expanding hole sleeve 31 is provided in the sealing groove. A retaining ring 50 is fixedly provided on the lower end of the upper expanding sleeve 31 to prevent the upper expanding telescopic rod 32 from separating from the upper expanding sleeve 31. The upper expanding terminal 33 is detachably fixed in the upper end slot 34 by a third screw 53.

[0022] In some embodiments, the lower expansion terminal 22 and the upper expansion terminal 33 have the same structure and the two sides of the working end are triangular, and the two sides of the triangle are rounded. The end of the working end is provided with a spherical end. This structure can better deform the end of the shock absorber pin 3 without causing damage to the shock absorber pin 3.

[0023] In some embodiments, the isoangular rotation assembly includes an inclined plate seat 36, a positioning shaft 37, a rotating tray 38, a rotation drive 39, and a transmission component.

The inclined plate seat 36 is fixed to the base 1 with screws and is used to install the positioning shaft 37, rotating tray 38, rotating drive component 39, and transmission components. An inclined surface is provided on the top of the inclined plate seat 36. The axis of the positioning shaft 37 is perpendicular to the inclined surface. Because the shock-absorbing holes are inclined on the turbine disk 2, they are not parallel to the axis of the turbine disk. The rotating drive component 39 is a servo motor, which drives the worm gear 41 to rotate. The worm gear 41 drives the turbine 40 to rotate. The turbine 40 is coaxially fixedly connected to the lower end of the rotating tray 38, so the turbine 40 and the rotating tray 38 rotate synchronously on the positioning shaft 37. The upper end of the rotating tray 38 is provided with end face teeth 52, which engage with the side teeth on the turbine disk 2, thereby enabling the rotating tray 38 and the turbine disk 2 to rotate synchronously. The positioning shaft 37, rotating tray 38, turbine disk 2, and turbine 40 are coaxially arranged. The rotation drive component 39 and the transmission components are arranged in the inclined seat 36, making the overall structure more compact and protecting the rotation drive component 39. To reduce the resistance of the rotating tray 38, an end face bearing 51, as used in the prior art, is provided between the bottom of the turbine 40 and the inclined seat 36, or an end face bearing 51 is provided between the rotating tray 38 and the inclined seat 36. The end face bearing 51 is coaxially arranged with the positioning shaft 37.
