Description

Technical Field

[0001] This invention relates to the field of blade processing technology, and in particular, to a blade tenon broaching and adjustment clamping device. Background Technology

[0002] The working blades 100 of an aero-engine or gas turbine compressor are an important component of the compressor, such as... Figure 1 As shown, the blade 100 includes a blade body 101 and a tenon 102. The allowance of the blade body 101 is more than 0.8mm. The tenon 102 serves as the assembly positioning reference for the blade 100 and is generally given priority in machining in the machining process. The tenon 102 is machined by broaching or milling.

[0003] The existing technology processes the tenon 102 by broaching the tenon 102 while fixing the blade 101. Before broaching, the blade 100 is fitted into a square box, and after adjusting its posture, a low-melting-point alloy is poured into the square box to wrap the blade 101 and form an integral part with the square box. The positioning and clamping reference is transferred to the square box. After the square box cools down as a whole, it is placed on a broaching machine and pressed to broach the tenon 102. Finally, after broaching, the square box is placed in hot oil to melt the alloy. Only after removing the blade 100 can the dimensions of the tenon 102 and the allowance of the blade 101 be measured.

[0004] The entire process of pouring the alloy into the box until it melts is cumbersome and takes a long time. There is a risk of burns during the process, which leads to relatively low processing efficiency and is not conducive to mass production. In addition, there is a risk of contamination by low-melting-point alloys, which affects the surface quality of the compressor blades and processing efficiency. Summary of the Invention

[0010] Furthermore, the clamping assembly includes a clamping block mounted on the rotating assembly, a support rod disposed below the clamping block, and a height adjustment member disposed on the support rod for abutting the bottom end of the tenon.

[0011] Further, the rotating assembly includes a support, a first rotating plate rotatably disposed on the support, a first driving member for driving the first rotating plate to rotate relative to the support, and a second locking member for limiting the relative position of the first rotating plate and the support. The clamping assembly is disposed on the first rotating plate. The first driving member includes a first rotating pin, a first eccentric wheel eccentrically disposed on the first rotating pin, and a first handle for driving the first rotating pin to rotate. The first rotating plate has a first opening. The first end of the first rotating pin is rotatably mounted on the support. The second end of the first rotating pin passes through the first opening and is connected to the first handle. The first eccentric wheel is embedded in the first opening. The first handle is used to drive the first rotating pin to rotate along its own axis so that the first eccentric wheel deflects, thereby driving the first rotating plate to rotate through the cooperation of the first eccentric wheel and the first opening.

[0012] Furthermore, the swing assembly includes a cylindrical pin disposed on the base, a second rotating plate rotatably connected to the cylindrical pin, a second driving member for driving the second rotating plate to rotate relative to the base, and a third locking member for limiting the relative position of the second rotating plate and the base.

The second end of the second rotating pin passes through the second opening and is connected to the second handle. The second eccentric wheel is embedded in the second opening. The second handle is used to drive the second rotating pin to rotate along its own axis so that the second eccentric wheel deflects, thereby driving the second rotating plate to rotate through the cooperation of the second eccentric wheel and the second opening.

[0013] Furthermore, the base is provided with a support mechanism for supporting the drawing box, and a slider is provided on the bottom surface of the drawing box. The support mechanism includes a first guide plate arranged along the central axis of the blade and a limiting pin for limiting the position of the slider relative to the first guide plate.

[0015] Furthermore, the adjustment plate is provided with a first drawing template for detecting the cross-sectional allowance at the root of the blade and a second drawing template for detecting the cross-sectional allowance at the tip of the blade.

[0016] The present invention has the following beneficial effects: The blade tenon broaching and adjustment clamping device of the present invention, in use, inserts the blade into the square box body. Due to the large torsion angles of each section of the blade profile, it is necessary to fully release the locking mechanism on the square box body to allow the blade to be smoothly inserted into the square box body. Then, the blade and the broaching square box are placed on the base, and the tenon is clamped by the clamping component of the clamping mechanism. The rotating component drives the clamping component to rotate around the blade's central axis L, which can adjust the posture of the blade in the square box body. The swinging component can drive the rotating component to swing on the top surface of the base, so that the clamping mechanism can move the blade relative to the broaching square box through the tenon. It can adjust the position of the blade within the square box body; when the blade moves to the designated position within the square box body and is adjusted to the designated posture, the blade is fixed by the locking mechanism on the square box body, allowing the broaching square box to be removed for broaching of the tenon; it can effectively replace the method of casting low-melting-point alloy into the broaching square box to wrap and fix the blade, avoiding the risk of burns and contamination from low-melting-point alloy; fixing the blade with the locking mechanism simplifies the blade fixing process, significantly shortens the blade fixing time, thereby improving the blade clamping efficiency, reducing processing costs, and making it suitable for batch processing of blades.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0024] To better understand the above technical solution, the following detailed explanation is provided in conjunction with the accompanying drawings.

[0025] Please refer to the following: Figures 1 to 18 The blade tenon broaching and clamping device of this embodiment includes a base 1, a broaching box 2 for fixing the blade 101 when it moves to a designated position, and a clamping mechanism 3 for clamping the tenon 102 and adjusting the relative position of the blade 101 and the broaching box 2 through the tenon 102. The broaching box 2 and the clamping mechanism 3 are arranged on the base 1. The clamping mechanism 3 includes a clamping component 31 for clamping the tenon 102, a rotating component 32 for driving the clamping component 31 to rotate around the blade central axis L and positioning it after the clamping component 31 rotates to a designated position, and a swinging component 33 for driving the rotating component 32 to sway and positioning it after the rotating component 32 swings to a designated position. The broaching box 2 includes a box body 21 and a locking mechanism 22 arranged on the box body 21 for fixing the blade 101.

[0026] In this embodiment, the blade tenon broaching and adjustment clamping device is used by inserting the blade 101 into the square box body 21. Due to the large torsion angles of each section of the blade 101, the locking mechanism 22 on the square box body 21 needs to be fully released to allow the blade 101 to be smoothly inserted into the square box body 21. Then, the blade 100 and the broaching square box 2 are placed on the base 1. The tenon 102 is clamped by the clamping component 31 of the clamping mechanism 3. The rotating component 32 drives the clamping component 31 to rotate around the blade's central axis L, which can adjust the posture of the blade 101 in the square box body 21. The swing component 33 can drive the rotating component 32 to swing on the top surface of the base 1, so that the clamping mechanism 3 can drive the blade 101 relative to the broaching square box through the tenon 102. 2. The movement allows adjustment of the blade 101's position within the square box body 21. When the blade 101 moves to the designated position within the square box body 21 and is adjusted to the designated posture, the blade 101 is fixed by the locking mechanism 22 on the square box body 21. This allows the broaching square box 2 to be removed for broaching of the tenon 102. This effectively replaces the method of casting low-melting-point alloy into the broaching square box 2 to wrap and fix the blade 101, avoiding the risks of burns and low-melting-point alloy contamination. Fixing the blade 101 via the locking mechanism 22 simplifies the blade 101 fixing process, significantly shortens the fixing time, improves the clamping efficiency of the blade 101, reduces processing costs, and is suitable for batch processing of blades. Optionally, multiple support feet 11 are arranged on the bottom surface of the base 1. The support feet 11 are screwed to the base 1. By rotating the support feet 11, the support height of each support foot 11 can be adjusted to ensure that the base 1 is in a horizontal state.

[0027] like Figure 3 , Figure 9 and Figure 12 As shown, in this embodiment, the locking mechanism 22 includes a first top block assembly 221 for abutting the back of the leaf body 101, a second top block assembly 222 for abutting the leaf base of the leaf body 101, and a first abutting screw 223 for limiting the height position of the leaf body 101 within the box body 21. The first top block assembly 221 and the second top block assembly 222 are arranged opposite to each other on the two side walls of the box body 21, and a plurality of first abutting screws 223 are respectively arranged on the top plate and the bottom plate of the box body 21. On the base plate, the first top block assembly 221 and the second top block assembly 222 of the through rod cooperate horizontally to clamp the blade head and blade back of the blade body 101. The first abutting screw 223 on the top plate of the square box body 21 and the first abutting screw 223 on the bottom plate of the square box body 21 cooperate vertically to fix the height position of the blade body 101, so that the blade body 101 is firmly clamped in the square box body 21. The structure is ingenious and can effectively replace the method of casting low melting point alloy into the drawing square box 2 to wrap and fix the blade body 101.

[0028] like Figures 9 to 14As shown, in this embodiment, the first top block assembly 221 includes a first screw 2211 screwed to the side wall of the box body 21, a first adapter sleeve 2212 rotatably disposed on the first screw 2211, and a first profiled top block 2213 hinged to the first adapter sleeve 2212. The first profiled top block 2213 is adapted to the back of the blade body 101. The second top block assembly 222 includes a second screw 2221 screwed to the side wall of the box body 21, a second adapter sleeve 2222 rotatably disposed on the second screw 2221, and a first profiled top block 2213 hinged to the second adapter sleeve 2212. The second profile top block 2223 is hinged to the blade base of the blade body 101. By rotating the first screw 2211 and the second screw 2221, the first profile top block 2213 and the second profile top block 2223 can move towards or away from each other, thereby clamping or loosening the blade body 101. The hinged connection between the first profile top block 2213 and the first adapter sleeve 2212 and the hinged connection between the second profile top block 2223 and the second adapter sleeve 2222 can flexibly adapt to the rotation angle, ensuring that the blade can be smoothly inserted into the square box body 21.

[0029] like Figure 9 As shown, in this embodiment, two first top block assemblies 221 are arranged at intervals along the central axis L of the blade, and the second top block assemblies 222 are arranged in a one-to-one correspondence with the first top block assemblies 221. Eight second abutting screws 224 are arranged between two adjacent first top block assemblies 221 for abutting the back of the blade body 101 after passing through the side wall of the box body 21. Eight second abutting screws 224 are arranged between two adjacent first top block assemblies 221 for abutting the blade head of the blade body 101 after passing through the side wall of the box body 21. The second abutting screws 224 can abut the back of the blade and the blade head in the middle of the blade body 101, further enhancing the stability of the blade body 101 fixation, which is conducive to the uniform force on the blade body 101 and can prevent the blade body 101 from deforming during the processing of the tenon 102. It can be understood that the number of first top block assemblies 221 can also be three, four or more, and the number of second abutting screws 224 can be increased or decreased according to the requirements.

[0030] like Figure 2 , Figure 3 , Figure 6As shown, in this embodiment, the clamping assembly 31 includes a clamping block 311 mounted on the rotating assembly 32, a support rod 312 disposed below the clamping block 311, and a height adjusting member 313 disposed on the support rod 312 for abutting the bottom end of the tenon 102. The clamping block 311 is provided with a clamping groove 314 for inserting the tenon 102 and a first locking member 315 for locking the tenon 102. After the tenon 102 is inserted into the clamping groove 314, the support height of the height adjusting member 313 is adjusted so that the height of the blade 101 in the square box body 21 reaches a specified position. The first locking member 315 is tightened to fix the tenon 102 on the clamping block 311 so that the clamping block 311 can drive the blade 101 to move through the tenon 102. Optionally, the first locking member 315 is a locking screw. After the locking screw is screwed to the clamping block 311, it extends into the clamping groove 314 to abut the tenon 102. Optionally, the support rod 312 is fixedly installed below the clamping assembly 31. The height adjustment component 313 is a screw, one end of which is screwed to the support rod 312, and the other end abuts against the bottom surface of the tenon 102. The support height of the screw against the bottom surface of the tenon 102 is adjusted by rotating the screw. This structure is simple and cost-effective. Alternatively, the support rod 312 is fixedly installed below the clamping assembly 31. The height adjustment component 313 is a servo motor-driven linear telescopic mechanism. The fixed end of the linear telescopic mechanism is installed on the support rod 312, and the free end of the linear telescopic mechanism abuts against the bottom surface of the tenon 102. The height of the support for the bottom surface of the tenon 102 is precisely controlled by the servo motor, resulting in a high degree of automation and high adjustment accuracy.

[0031] like Figure 2 , Figure 4 , Figure 5 , Figure 15 , Figure 17 and Figure 18As shown, in this embodiment, the rotating assembly 32 includes a support 321, a first rotating plate 322 rotatably disposed on the support 321, a first driving member 323 for driving the first rotating plate 322 to rotate relative to the support 321, and a second locking member 324 for limiting the relative position of the first rotating plate 322 and the support 321. The clamping assembly 31 is disposed on the first rotating plate 322. The first driving member 323 includes a first rotating pin 3231 and an eccentrically disposed on the first rotating pin 3231. The first eccentric wheel 3232 and the first handle 3233 for driving the first rotating pin 3231 to rotate are provided. The first rotating plate 322 has a first opening 3221. The first end of the first rotating pin 3231 is rotatably mounted on the support 321. The second end of the first rotating pin 3231 passes through the first opening 3221 and is connected to the first handle 3233. The first eccentric wheel 3232 is embedded in the first opening 3221. The first handle 3233 is used to drive the first rotating pin 3231 to rotate. 231 rotates along its own axis to deflect the first eccentric wheel 3232, thereby driving the first rotating plate 322 to rotate through the cooperation of the first eccentric wheel 3232 and the first window 3221; the support rod 312 and the clamping block 311 are installed on the first rotating plate 322, and the outer circumference of the first eccentric wheel 3232 abuts against the first window 3221. When it is necessary to drive the blade 100 to adjust its posture, the second locking member 324 is released, and the first handle 3233 is turned to drive the first eccentric wheel 3232 to rotate. As the first eccentric wheel 3232 rotates, its outer circumference abuts against the first opening 3221, causing the first rotating plate 322 to rotate around the blade's central axis L. After the blade 100 rotates to the designated position, locking the second locking member 324 positions the blade 101 within the square box body 21. Rotating the first eccentric wheel 3232 against the first opening 3221 causes the first rotating plate 322 to rotate, resulting in high adjustment precision, suitable for fine-tuning the blade 101's posture. Optionally, the first rotating plate 322 is provided with a first positioning pin 3223, and the support 321 is provided with a first reference hole adapted to the first positioning pin 3223. When the first positioning pin 3223 is inserted into the first reference hole, the first rotating plate 322 is in its initial position, facilitating its reset. Optionally, the second locking component 324 includes a screw 3241, a pressure cap 3242, and a locking nut 3243. The first rotating plate 322 is provided with a central hole 3222 coaxial with the blade central axis L. The pressure cap 3242 is connected to the support 321. One end of the screw 3241 is fixedly connected to the central hole 3222, and the other end of the screw 3241 passes through the pressure cap 3242 and is screwed to the locking nut 3243. The first rotating plate 322 can be locked / loosened by rotating the locking nut 3243.

[0032] like Figure 2 , Figure 4 , Figure 5 , Figure 16 , Figure 17and Figure 18 As shown, in this embodiment, the swing assembly 33 includes a cylindrical pin 331 disposed on the base 1, a second rotating plate 332 rotatably connected to the cylindrical pin 331, a second driving member 333 for driving the second rotating plate 332 to rotate relative to the base 1, and a third locking member 334 for limiting the relative position of the second rotating plate 332 and the base 1. The support 321 of the swing assembly 32 is disposed on the second rotating plate 332. The second driving member 333 includes a second rotating pin 3331 and an eccentrically disposed on the second rotating pin 331. The second eccentric wheel 3332 on the second rotating plate 332 and the second handle 3333 for driving the second rotating pin 3331 to rotate are located on the base 1. The second rotating plate 332 has a second opening 3321. The first end of the second rotating pin 3331 is rotatably mounted on the base 1. The second end of the second rotating pin 3331 passes through the second opening 3321 and is connected to the second handle 3333. The second eccentric wheel 3332 is embedded in the second opening 3321. The second handle 3333 is used to drive the second rotating pin 3331 along its own axis. Rotation causes the second eccentric wheel 3332 to deflect, thereby driving the second rotating plate 332 to rotate through the cooperation of the second eccentric wheel 3332 and the second window 3321. The structure of the second rotating pin 3331 is the same as that of the first rotating pin 3231, and the structure of the second eccentric wheel 3332 is the same as that of the first eccentric wheel 3232. The outer circumference of the second eccentric wheel 3332 abuts against the second window 3321. When it is necessary to drive the blade 100 to deflect, the third locking member 334 is released, and the second handle 3333 is rotated to drive the second eccentric wheel 100 to deflect. As the second eccentric wheel 3332 rotates, its outer circumference abuts against the second opening 3321, causing the second rotating plate 332 to sway around the cylindrical pin 331. After the blade 100 sways to the designated position, locking the third locking member 334 positions the blade body 101 relative to the square box body 21. By rotating the second eccentric wheel 3332 against the second opening 3321, the second rotating plate 332 sways, achieving high adjustment precision, suitable for fine-tuning the position of the blade body 101. Optionally, the second rotating plate 332 has an arc-shaped groove 3322, and the third locking member 334 is a locking screw. The locking screw passes through the arc-shaped groove 3322 and is screwed to the base 1. Rotating the locking screw can fix / loosen the second rotating plate 332, making the structure simple and the operation convenient. Optionally, a second positioning pin 3323 is provided on the second rotating plate 332, and a second reference hole adapted to the second positioning pin 3323 is provided on the base 1. When the second positioning pin 3323 is inserted into the second reference hole, the second rotating plate 332 is in the initial position, which facilitates the reset of the second rotating plate 332.

[0033] like Figure 5 , Figure 6 and Figure 9As shown, in this embodiment, a support mechanism 4 for supporting the drawing box 2 is provided on the base 1. A slider 23 is provided on the bottom surface of the drawing box 2. The support mechanism 4 includes a first guide plate 41 arranged along the central axis L of the blade and a limiting pin 42 for limiting the position of the slider 23 and the first guide plate 41. A first groove is formed between two spaced first guide plates 41. The slider 23 is slidably arranged in the first groove. The limiting pin 42 is arranged in the first groove to limit the position of the slider 23 and prevent the drawing box 2 from slipping off the first guide plate 41. In use, the blade 100 and the drawing box 2 are placed on the first guide plate 41 as a whole. The slider 23 slides along the first groove until the slider 23 abuts against the limiting pin 42. At this time, the tenon 102 is inserted into the clamping groove 314. The structure is simple and the operation is convenient.

[0034] like Figure 1 and Figure 6 As shown, in this embodiment, the support mechanism 4 further includes a second guide plate 43 arranged along the direction perpendicular to the blade central axis L, an adjustment plate 44 slidably connected to the second guide plate 43, and a lateral adjustment member 45 for adjusting the relative position of the adjustment plate 44 and the second guide plate 43 and limiting the adjustment plate 44 when it reaches the specified position. The first guide plate 41 and the limiting pin 42 are arranged on the adjustment plate 44. A second slide groove is formed between the two oppositely arranged second guide plates 43. The adjustment plate 44 is slidably arranged in the second slide groove. The position of the adjustment plate 44 in the second slide groove is adjusted by the lateral adjustment member 45. If the allowance on both sides of the blade base and blade back is uneven, the lateral position of the adjustment plate 44 is adjusted by the lateral adjustment member 45. The adjustment plate 44 drives the broaching box 2 to adjust its position, which can accurately adjust the relative and reasonable posture of the tenon 102 and the blade body 101, so as to meet both the clamping requirements for mounting the blade body 101 and the broaching requirements for the tenon 102. Optionally, the lateral adjustment components 45 are symmetrically arranged on both sides of the base 1. Each lateral adjustment component 45 includes a mounting base on the base plate and a push rod screwed to the mounting base. When one push rod extends, the other push rod retracts, thereby adjusting the lateral position of the adjustment plate 44 and preventing the adjustment plate 44 from shifting. This design is simple in structure and low in manufacturing cost. Optionally, the lateral adjustment component 45 is a servo motor-driven linear telescopic device. The fixed end of the linear telescopic device is located on the base 1, and the free end is connected to the adjustment plate 44. This design offers a high degree of automation and can precisely control the constant position of the adjustment plate 44. Optionally, the middle portion of each second guide plate 43 is cut off to reduce the overall weight of the device.

[0035] like Figure 2 and Figure 4As shown, in this embodiment, the adjusting plate 44 is provided with a first drawing template 5 for detecting the cross-sectional allowance at the root of the blade 101 and a second drawing template 6 for detecting the cross-sectional allowance at the tip of the blade 101. The first drawing template 5 and the second drawing template 6 are fitted to the beginning and end sections of the blade 101 to check the size of the light transmission gap, ensuring that the light transmission size on the blade profile, blade base, and blade back sides is consistent, i.e., the allowance on both sides of the blade profile, blade base, and blade back is relatively uniform. If the profiles do not fit, the first driving member 323 drives the first rotating plate 322 to rotate, thereby adjusting the blade 101 to rotate around the central axis L to adjust the posture of the blade 101. If the allowance on both sides of the blade base and blade back is inconsistent, the first driving member 323 drives the first rotating plate 322 to rotate, thereby adjusting the blade 101 to rotate around the central axis L. The second driving component 333 drives the second rotating plate 332 to swing, adjusting the size of the light transmission gap between the blade (blade basin, blade back) and the first broaching template 5 and the second broaching template 6. Before adjustment, the third locking component 334 is loosened, and after adjustment, the third locking component 334 is tightened to fix it. If the allowance on both sides of the blade basin and blade back is uneven, the lateral position of the adjusting plate 44 is adjusted by the lateral adjusting component 45. The adjusting plate 44 drives the broaching square box 2, the first broaching template 5 and the second broaching template 6 to adjust their positions synchronously, which can accurately adjust the relative and reasonable posture of the tenon 102 and the blade 101, so as to meet both the clamping requirements of the blade 101 and the broaching processing requirements of the tenon 102.
