Description

Technical Field

[0001] This utility model relates to the technical field of aero-engine turbine blade production equipment, and in particular to a straightening device for aero-engine blade wax molds. Background Technology

[0002] Aero-engine blade wax models are a key intermediate product in the precision casting process of aero-engine blades. Due to the complex shape of aero-engine blades and the high requirements for dimensional accuracy, the blade profile, torsion angle, thickness distribution, etc. are all determined by aerodynamic design optimization. Dimensional deviations will change the flow state of airflow on the blade surface. For example, excessive blade thickness will change the blade's lift-to-drag ratio, directly affecting the compressor's compression efficiency or the turbine's work capacity. Therefore, the dimensional accuracy requirements for the manufactured aero-engine blade wax models are very high.

[0003] Furthermore, in the current process of forming aero-engine blade wax molds, molten wax is injected into a molding die and held at a certain pressure and temperature for a period of time to allow the wax to cool and solidify, forming the aero-engine blade wax mold. Due to factors such as wax characteristics and mold performance, the dimensions of the formed aero-engine blade wax mold are prone to deviation. To inspect the quality of the formed aero-engine blade wax mold, existing technologies use high-precision measuring equipment such as coordinate measuring machines to measure the shape and size of the aero-engine blade wax mold. If the error of the solidified aero-engine blade wax mold exceeds the allowable error range, it is necessary to correct the formed aero-engine blade wax mold using a wax mold straightening mold. However, when using the existing wax mold straightening method to straighten the formed aero-engine blade wax mold, due to the deficiencies in the structural design of the wax mold straightening mold, the adjustment precision of the extrusion block used to extrude the aero-engine blade wax mold by the straightening operator is unstable, resulting in unstable straightening precision of the aero-engine blade wax mold and affecting the quality of the aero-engine blade wax mold obtained after straightening. Therefore, there is an urgent need for a correction device that can improve the accuracy and stability of the correction of wax models for aero-engine blades. Summary of the Invention

[0004] The purpose of this invention is to overcome at least one deficiency of the prior art and to provide a straightening device that is beneficial to improving the accuracy and stability of straightening wax models of aero-engine blades.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A straightening device for aero-engine blade wax molds according to this application includes: Base; A blade straightening seat is mounted on the base. The blade straightening seat includes a mounting body, a lower straightening block, and an upper straightening block. The mounting body is mounted on the base. The lower straightening block is oscillatingly mounted on the mounting body and can oscillate relative to the mounting body in the height direction. The upper side of the lower straightening block has an arc-shaped groove with an open upper side. The upper straightening block is rotatably mounted on the lower straightening block and can rotate in the height direction. The lower side of the upper straightening block has an arc-shaped protrusion. The upper straightening block's ability to rotate relative to the lower straightening block in the height direction allows it to compress the wax model blade. The correction includes a compression correction position one and a deviation position one relative to the blade profile of the wax model; the aircraft engine blade wax model is placed between the arc-shaped groove one and the arc-shaped protrusion one; when the upper correction block one is placed at the compression correction position one, the blade profile segment correction channel one is defined between the arc-shaped groove one and the arc-shaped protrusion one, and the inner wall of the blade profile segment correction channel one compresses and corrects the profile of the blade profile segment one directly opposite it; when the upper correction block one is located at the deviation position one, the inner wall of the blade profile segment correction channel one releases the compression on the profile of the blade profile segment one directly opposite it. The lower side of the mounting body is provided with a stop slope, which is inclined from left to right from low to high. The base is provided with a body mounting part on the upper side of the mounting body, which extends in the left and right direction. A height adjustment mechanism is installed between the base and the mounting body, and the mounting body can adjust its height in the vertical direction under the adjustment of the height adjustment mechanism.

[0006] The beneficial effects of this utility model are as follows: In this embodiment, the lower straightening block and the upper straightening block provided on the blade straightening seat act on the blade simultaneously. When the upper straightening block is placed in the compression straightening position, the blade contour segment straightening channel formed between the arc-shaped groove and the arc-shaped protrusion facilitates the inner wall of the blade contour segment straightening channel to compress and straighten the contour of the blade contour segment directly opposite it. Furthermore, the height adjustment mechanism is installed between the base and the mounting body, which facilitates adjusting the height position of the mounting body in the vertical direction, and thus facilitates adjusting the height position of the blade contour segment straightening channel in the vertical direction. This allows the inner wall of the blade contour segment straightening channel to accurately compress and straighten the contour of the blade contour segment directly opposite it, which helps to improve the accuracy and stability of the straightening of the aero-engine blade wax model, and thus helps to improve the quality of the aero-engine blade wax model obtained after straightening.

[0007] In addition, based on the above technical solution, the present invention can be further improved as follows, and can also have the following additional technical features.

[0009] In this embodiment, the lower side of the mounting body 1 is provided with a guide limiting groove 5, and the guide rail 1 is fixed in the guide limiting groove 5 on the lower side of the mounting body. This facilitates the sliding of the guide rail 1 relative to the guide limiting block 1, and in turn, facilitates the sliding of the height adjustment slider relative to the mounting body 1. The stop slope 1 on the lower side of the mounting body and the stop slope 2 on the upper side of the height adjustment slider mutually stop each other, which facilitates the sliding of the height adjustment slider in the left and right directions under the action of the push rod. Furthermore, both the stop slope 1 and the stop slope 2 are inclined from left to right from low to high. When the height adjustment slider slides in the left and right directions, it is beneficial for the mounting body 1 to change its vertical height position under the action of the height adjustment slider. This is beneficial for adjusting the vertical height position of the blade profile section straightening channel 1, so that the inner wall of the blade profile section straightening channel 1 can accurately squeeze and straighten the profile of the blade profile section 1 that is directly opposite it. This improves the accuracy and stability of the straightening of the aero-engine blade wax model, and is beneficial for improving the quality of the aero-engine blade wax model obtained after straightening.

[0010] According to one embodiment of this application, the upper side of the height adjustment slider is provided with a guide limiting groove two facing the guide limiting groove one. The guide limiting groove two extends out of the height adjustment slider along the extending direction of the guide limiting groove one. The upper side of the height adjustment slider is also provided with an installation and storage groove one. The guide limiting block one is installed in the installation and storage groove one. When the guide limiting block one is installed in the installation and storage groove one, the guide limiting groove one and the guide limiting groove two are connected, and the guide rail one is slidably installed in the guide limiting groove one and the guide limiting groove two.

[0011] In this embodiment, the upper side of the height adjustment slider is provided with a mounting and storage groove 1, which is conducive to installing the guide limiting block 1 in the mounting and storage groove 1; the guide limiting groove 2 is connected to the guide limiting groove 1 and extends out of the height adjustment slider along the extension direction of the guide limiting groove 1, which is conducive to sliding the guide rail 1 along the length direction of the push rod on the guide limiting groove 1 and the guide limiting groove 2. When the height adjustment slider slides along the length direction of the push rod, it is conducive to reducing the sliding friction between the height adjustment slider and the device or mechanism installed on the upper part of the guide rail 1.

[0012] According to one embodiment of this application, the height adjustment mechanism further includes: Guide rail two is installed on the lower side of the height adjustment slider. The extension direction of guide rail two is the same as that of guide rail one. The lower side of guide rail two is lower than the lower side of the height adjustment slider in the height direction. The second guide limit block is fixedly installed on the mounting part of the main body. The upper side of the second guide limit block is provided with the third guide limit groove. The third guide limit groove extends through the second guide limit block along the length direction of the push rod. The lower side of the second guide rail extends into the third guide limit groove and can slide along the extension direction of the third guide limit groove under the limitation of the third guide limit groove.

[0013] In this embodiment, by providing a guide limiting groove three on the upper side of the guide limiting block two, it is beneficial to slide the guide rail two on the guide limiting block two, thereby facilitating the sliding of the height adjustment slider located on the upper part of the guide rail two relative to the guide limiting block two.

[0014] According to one embodiment of this application, the lower side of the height adjustment slider is provided with a guide limiting groove four, the guide limiting groove four extends out of the height adjustment slider along the extension direction of the guide limiting groove three, and the guide rail two is installed in the guide limiting groove four.

[0015] In this embodiment, the lower side of the height adjustment slider is provided with a guide limiting groove four, and the guide limiting groove four extends out of the height adjustment slider along the extension direction of the guide limiting groove three. This facilitates the installation of the guide rail two in the guide limiting groove four, thereby making it easier for the height adjustment slider located on the upper part of the guide rail two to slide relative to the guide limiting block two.

[0016] According to one embodiment of this application, the straightening device for aero-engine blade wax molds further includes: A height adjustment reference scale is provided on the upper side of the base. The height adjustment reference scale is used to reference the distance that the height adjustment slider slides between the base and the mounting body in the left and right direction. The reference baseline is set on the height adjustment slider, directly opposite the height adjustment reference scale.

[0017] In this embodiment, by setting a height adjustment reference scale and a reference baseline, it is beneficial to accurately adjust the distance the height adjustment slider slides in the left and right directions, which in turn is beneficial to accurately adjust the height position of the mounting body and the lower straightening block on it in the vertical direction, thereby improving the accuracy and stability of straightening the wax model of the aero-engine blade.

[0018] According to one embodiment of this application, the straightening device for aero-engine blade wax molds further includes: A swing drive mechanism is installed between the lower orthotic block and the mounting body. The lower orthotic block can swing relative to the mounting body in the height direction under the drive of the swing drive mechanism. The upper orthotic block can swing in the height direction as the lower orthotic block swings. The upper orthotic block can rotate in the height direction relative to the swinging lower orthotic block to have the compression correction position and the deviation position.

[0019] In this embodiment, the lower straightening block 1 is driven to swing relative to the mounting body 1 in the height direction by the swing drive mechanism. This allows the upper straightening block 1 to move relative to the lower straightening block 1 in the height direction to have a compression correction position 1. When the upper straightening block 1 is in the compression correction position 1, the blade profile segment straightening through groove 1 and the arc-shaped protrusion 1 are defined by the swing drive mechanism to drive the lower straightening block 1 to rotate, thereby driving the upper straightening block 1 to be placed in the compression correction position 1. This allows the contour of the blade profile segment straightening through groove 1 defined between the arc-shaped groove 1 and the arc-shaped protrusion 1 to match the contour that the blade profile segment 1 needs to be formed. This, in turn, allows the inner sidewall of the blade profile segment straightening through groove 1 to compress and correct the contour of the blade profile segment 1 that is directly opposite it, improving the accuracy and stability of the straightening of the aero-engine blade wax model and improving the quality of the aero-engine blade wax model obtained after straightening.

[0020] According to one embodiment of this application, the first end of the mounting body in the left-right direction is provided with a support block, and the first end of the lower orthopedic block is provided with a push protrusion in the height direction directly opposite the support block, and the push protrusion is located above the support block. The support block and the push protrusion have a spacing to form an adjustable pad embedding groove. The swing drive mechanism includes: An adjusting pad is detachably embedded in the pad embedding groove. During the process of embedding the adjusting pad into the pad embedding groove, the lower side of the adjusting pad abuts against the upper side of the support block, and the upper side of the adjusting pad pushes against the lower side of the pushing protrusion, causing the lower orthopedic block to swing relative to the mounting body in the height direction, and the upper orthopedic block to rotate relative to the swinging lower orthopedic block in the height direction. When the adjusting pad is fully embedded in the pad embedding groove, the upper orthopedic block is positioned at the compression correction position one. When the adjusting pad is removed from the pad embedding groove, the upper orthopedic block can rotate relative to the lower orthopedic block in the height direction to the deviation position one.

[0021] In this embodiment, by embedding the adjusting pad in the pad embedding groove, the lower straightening block 1 swings relative to the mounting body 1 in the height direction under the action of the adjusting pad. When the adjusting pad is fully embedded in the pad embedding groove, the upper straightening block 1 is placed in the compression and correction position 1. At this time, the inner sidewall of the blade profile section straightening through groove 1 compresses and corrects the profile of the blade profile section 1 that is directly opposite it, which helps to make the blade profile section 1 obtain a profile that meets the requirements of the design drawings.

[0022] According to one embodiment of this application, the lower side of the adjusting pad forms a lower stop support surface, and the upper side of the adjusting pad is provided with a stepped structure to form an upper stop support surface one and an upper stop support surface two. The thickness between the upper stop support surface one and the lower stop support surface is a first thickness, and the thickness between the upper stop support surface two and the lower stop support surface is a second thickness. The first thickness is greater than the second thickness. An angle mark 1 is provided on the upper stop support surface 1, and an angle mark 2 is provided on the upper stop support surface 2; wherein, the angle mark 1 marks the angle at which the adjusting pad can push the lower orthopedic block 1 to swing relative to the mounting body 1 in the height direction when the first thickness is fully embedded in the pad insertion groove, and the angle mark 2 marks the angle at which the adjusting pad can push the lower orthopedic block 1 to swing relative to the mounting body 1 in the height direction when the second thickness is fully embedded in the pad insertion groove.

[0023] In this embodiment, by adjusting the first and second thicknesses of the pad, it is beneficial that the same adjusting pad can allow the lower straightening block one to swing at different angles relative to the mounting body one in the height direction, thereby improving the accuracy of straightening the wax model of the aero-engine blade. Furthermore, by providing angle mark one on the upper stop support surface one and angle mark two on the upper stop support surface two, angle mark one and angle mark two indicate the angle at which the lower straightening block one can swing relative to the mounting body one in the height direction, it is more convenient to select the corresponding angle mark one or angle mark two according to the angle at which the lower straightening block one swings relative to the mounting body one in the height direction.

[0024] According to one embodiment of this application, the mounting body 1 is provided with an arc-shaped mounting groove 1 with an upper open side in the front-rear direction, and the lower straightening block 1 is provided with an arc-shaped mounting protrusion 1 on its lower side. The arc-shaped mounting protrusion 1 is housed in the arc-shaped mounting groove 1 and can swing within the arc-shaped mounting groove 1. The mounting body one is also provided with an arc-shaped limiting protrusion one in the front-rear direction. The arc-shaped limiting protrusion one extends into the arc-shaped mounting groove one. The arc-shaped mounting protrusion one is provided with an arc-shaped limiting groove one directly opposite the arc-shaped limiting protrusion one. The arc-shaped limiting protrusion one extends into the arc-shaped limiting groove one. The arc-shaped limiting protrusion one can limit the angle of swing of the lower orthopedic block one relative to the mounting body one in the height direction.

[0025] In this embodiment, by housing the arc-shaped mounting protrusion 1 in the arc-shaped mounting groove 1, it is easier for the lower straightening block 1 to swing on the mounting body 1; by extending the arc-shaped limiting protrusion 1 into the arc-shaped mounting groove 1, it is beneficial to limit the swing angle of the lower straightening block 1 on the mounting body 1, thereby helping to avoid damage to the aero-engine blade wax model located in the straightening through groove 1 of the blade profile section by excessive swing angle during the swing process.

[0026] According to one embodiment of this application, the straightening device for aero-engine blade wax molds further includes: An auxiliary drive mechanism is installed between the mounting body and the lower orthopedic block, and the lower orthopedic block can swing in the height direction under the drive of the auxiliary drive mechanism, and the upper orthopedic block can swing in the height direction as the lower orthopedic block swings. The upper orthopedic block can rotate in the height direction relative to the swinging lower orthopedic block to have a suitable compression correction position and a deviation position.

[0027] In this embodiment, the lower orthopedic block is driven to swing in the height direction by an auxiliary drive mechanism. This facilitates the adjustment of the spacing between the support block and the push protrusion by adjusting the thickness of the adjustable pad in the pad embedding groove as needed. This makes it easier to embed the adjustable pad with a suitable thickness into the pad embedding groove, and also makes it easier for the lower side of the adjustable pad to abut against the upper side of the support block, and for the upper side of the adjustable pad to push against the lower side of the push protrusion, thereby improving the accuracy of placing the upper orthopedic block in the compression correction position.

[0044] In this embodiment, as Figure 3 As shown, in this embodiment, the lower side of the height adjustment slider 30 is provided with a guide limiting groove four, and the guide limiting groove four extends out of the height adjustment slider 30 along the extension direction of the guide limiting groove three. This facilitates the installation of the guide rail two 361 in the guide limiting groove four, thereby making it easier for the height adjustment slider 30 located on the upper part of the guide rail two 361 to slide relative to the guide limiting block two 36.

[0045] Furthermore, such as Figures 3 to 5 As shown, the main body mounting section is provided with a second mounting and storage groove 171 and a sixth guide and limiting groove 181. The second guide and limiting block 36 is fixedly installed in the second mounting and storage groove 171, and the sixth guide and limiting groove 181 extends out of the main body mounting section along the extension direction of the third guide and limiting groove. The base 1 is also provided with a main body stop block 12, which is located on the left and right sides of the mounting main body 31. The main body stop block 12 is provided with a main body mounting groove 121. Both ends of the mounting main body 31 are movably installed in the main body mounting groove 121. One end of the mounting main body 31 is also provided with a mounting hole 122. The push rod 304 passes through the mounting hole 122 and is threadedly connected to the mounting hole 122. One end of the push rod 304 is provided with a push mounting protrusion 3041, and one end of the height adjustment slider 30 is provided with a push mounting groove 303. The push mounting protrusion 3041 is fixedly installed in the push mounting groove 303.

[0046] Furthermore, such as Figures 3 to 5 As shown, when the guide limit block 2 36 is installed in the installation and storage groove 2 171, the guide limit block 2 36 is provided with limit stop blocks 2 362 on both sides; furthermore, the guide rail 2 361 is provided with guide rail mounting holes 2 3611, and the guide rail 2 361 is fixedly installed in the guide limit groove 4 by connecting the guide rail mounting holes 2 3611 with screws.

[0047] One embodiment of this application, such as Figures 1 to 5 As shown, the straightening device for aero-engine blade wax models also includes: A height adjustment reference scale is set on the upper side of the base 1. The height adjustment reference scale is used to reference the distance that the height adjustment slider 30 slides in the left and right direction between the base 1 and the mounting body 31. The reference baseline 305 is set on the height adjustment slider 30, directly opposite the height adjustment reference scale.

[0048] In this embodiment, as Figures 1 to 5As shown, in this embodiment, by setting a height adjustment reference scale and a reference baseline 305, it is beneficial to accurately adjust the distance that the height adjustment slider 30 slides in the left and right directions, which in turn is beneficial to accurately adjust the height position of the mounting body 31 and the lower straightening block 32 on it in the vertical direction, thereby improving the accuracy and stability of straightening the aero-engine blade wax model 8.

[0049] One embodiment of this application, such as Figure 1 , Figure 2 and Figure 4 As shown, the straightening device for aero-engine blade wax models also includes: A swing drive mechanism is installed between the lower orthotic block 32 and the mounting body 31. The lower orthotic block 32 can swing relative to the mounting body 31 in the height direction under the drive of the swing drive mechanism. The upper orthotic block 33 can swing in the height direction along with the swing of the lower orthotic block 32. The upper orthotic block 33 can rotate in the height direction relative to the swinging lower orthotic block 32 and has a compression correction position and a deviation position.

[0050] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the lower straightening block 32 is driven to swing relative to the mounting body 31 in the height direction by the swing drive mechanism. This is beneficial for the upper straightening block 33 to move relative to the lower straightening block 32 in the height direction to have a compression correction position. When the upper straightening block 33 is in the compression correction position, the blade profile section straightening channel 34 defined between the arc groove 321 and the arc protrusion 331 is driven by the swing drive mechanism to rotate the lower straightening block 32, thereby driving the upper straightening block 33 to be placed in the compression correction position. This is beneficial for the profile of the blade profile section straightening channel 34 defined between the arc groove 321 and the arc protrusion 331 to match the profile that the blade profile section 1 needs to be formed. This is beneficial for the inner wall of the blade profile section straightening channel 34 to compress and correct the profile of the blade profile section 1 that is directly opposite it, thereby improving the accuracy and stability of the straightening of the aero-engine blade wax model 8 and improving the quality of the aero-engine blade wax model 8 obtained after straightening.

[0051] Furthermore, such as Figure 1 , Figure 2 and Figure 5As shown, in this embodiment, a three-coordinate measuring reference column 19 is installed on one side of the blade contour section straightening groove 34, and the three-coordinate measuring reference column 19 is located in the middle of the upper side of the base 1. Multiple vertical support beams 11 are provided on the lower side of the base 1 to support the base 1. One end of the upper straightening block 33 is rotatably installed on one end of the lower straightening block 32, and the other end of the upper straightening block 33 is connected to the lower straightening block 32 through a latch 35.

[0052] Furthermore, such as Figure 1 and Figure 6 As shown, a tenon straightening seat 2 is also provided on the base 1, installed on the base 1 and located on the horizontal side of the blade straightening seat 3. The tenon straightening seat 2 includes a tenon mounting body 21, a lower tenon straightening block 22, and an upper tenon straightening block 23. The tenon mounting body 21 is installed on the base 1. The lower tenon straightening block 22 is sway-mounted on the tenon mounting body 21 and can swing relative to the tenon mounting body 21 in the height direction. The upper side of the lower tenon straightening block 22 is provided with an upper open arc-shaped groove for the tenon. One end of the tenon upper straightening block 23 is rotatably mounted on the tenon lower straightening block 22 and can rotate in the height direction. The other end of the tenon upper straightening block 23 is connected to the tenon lower straightening block 22 through the tenon straightening lock 25. The lower side of the tenon upper straightening block 23 is provided with a tenon arc-shaped groove. The tenon upper straightening block 23 can rotate relative to the tenon lower straightening block 22 in the height direction and has a tenon straightening position for positioning and straightening the wax model tenon and a tenon deviation position relative to the wax model tenon; for aircraft engines The tenon of the leaf wax model 8 is placed between the first and second arc-shaped grooves of the tenon. When the straightening block 23 on the tenon is positioned at the tenon's positioning and correction position, the tenon contour section straightening groove 24 formed between the first and second arc-shaped grooves of the tenon defines the tenon contour section straightening groove 24. The inner wall of the tenon contour section straightening groove 24 positions and corrects the tenon directly opposite it. When the straightening block 23 on the tenon is in a deviated position from the tenon, the inner wall of the tenon contour section straightening groove 24 releases its position on the tenon directly opposite it. The compression is fixed; furthermore, the swing drive mechanism is installed between the tenon lower straightening block 22 and the tenon mounting body 21, and the tenon lower straightening block 22 can swing relative to the tenon mounting body 21 in the height direction under the drive of the swing drive mechanism, and the tenon upper straightening block 23 can swing in the height direction with the swing of the tenon lower straightening block 22, and the tenon upper straightening block 23 can rotate in the height direction relative to the swinging tenon lower straightening block 22 to have a tenon correction position and a tenon deviation position.

[0053] In this embodiment, as Figure 1 and Figure 6As shown, in this embodiment, the blade tenon is placed between the tenon arc-shaped groove one and the tenon arc-shaped groove two on the tenon straightening seat 2. The swing drive mechanism drives the tenon lower straightening block 22 to swing relative to the tenon mounting body 21 in the height direction, so that the tenon upper straightening block 23 can swing in the height direction with the swing of the tenon lower straightening block 22. The tenon upper straightening block 23 can rotate in the height direction relative to the swinging tenon lower straightening block 22 to have a tenon straightening position and a tenon deviation position; thus, it is beneficial to form a torsion angle and a blade profile that meet the design requirements between the tenon and the blade body.

[0054] It should be noted that, as Figures 1 to 7 As shown, the connection method between the tenon mounting body 21 and the tenon lower straightening block 22 is the same as or similar to the connection method between the mounting body 31 and the lower straightening block 32. The connection method between the tenon mounting body 21 and the base 1 is the same as or similar to the connection method between the mounting body 31 and the base 1, and will not be described again here.

[0055] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the base 1 is also provided with a crown correction mounting groove 183, which is located on the horizontal side of the blade correction seat 3 away from the tenon correction seat 2. The base 1 is also provided with a crown correction seat 4, which is installed in the crown correction mounting groove 183. The crown correction seat 4 includes an upper crown mounting block and a lower crown mounting block. The lower crown mounting block is fixedly installed on the base 1, and a crown mounting groove adapted to the shape and size of the crown is formed on the upper side of the lower crown mounting block. One end of the upper crown mounting block is rotatably installed on the lower crown mounting block and can rotate in the height direction. The other end of the upper crown mounting block is connected to the lower crown mounting block through a crown lock. A crown positioning block is also provided on the lower side of the upper crown mounting block. A crown screw is provided on the upper crown mounting block opposite the crown positioning block. The crown positioning block has a crown screw that mates with the crown threaded hole. The crown screw can be used to adjust the vertical height of the crown positioning block. After the crown is placed into the crown mounting groove, the upper mounting block of the crown is fixed to the lower mounting block of the crown by the crown locking buckle. By adjusting the vertical height of the crown positioning block, the crown is fixed in the crown mounting groove. This helps to pre-fix the crown, thus preventing the crown from rotating when the blade profile is rotated to a suitable angle by the blade straightening seat 3, which would cause errors. It should be noted that the specific structure of the crown straightening seat 4 is not illustrated and described in detail in this embodiment. The specific structure and installation method of the crown straightening seat 4 can also refer to the existing technology in this field, and will not be repeated here.

[0056] Furthermore, such as Figures 1 to 7As shown, the straightening device for the wax model of the aero-engine blade in this embodiment also includes one or more of the following: blade straightening seat 2 5, blade straightening seat 3 6, and blade straightening seat 4 7. The structures of blade straightening seat 2 5, blade straightening seat 3 6, and blade straightening seat 4 7 are similar to those of blade straightening seat 1 3, and will not be described in detail here. It should be noted that blade straightening seat 1 3, blade straightening seat 2 5, blade straightening seat 3 6, and blade straightening seat 4 7 are located at different positions along the blade length and are used to straighten blade profile segments corresponding to different positions. Blade profile segment 1 is one of multiple blade profile segments. The cross-section of the aero-engine turbine blade is as follows: The irregular "banana shape" of the aero-engine blade wax model results in different shapes for the blade profile segments at different positions along the blade length. Therefore, the profiles of the blade profile segment straightening grooves formed on the blade straightening seats 1-3, 2-5, 3-6, and 4-7 for straightening different blade profile segments are all different. This facilitates the straightening of blade profile segments located at different positions along the blade length and improves the accuracy of the straightening process. Furthermore, after the straightening of the blade profile segments is completed, the blade profile of the aero-engine blade wax model conforms to the design requirements of the drawings.

[0057] It should be noted that for the correction of a wax model for an aero-engine blade, one or more correction devices can be used to correct the blade profile segments that need correction at different positions along the blade length. Moreover, when using multiple correction devices, the different correction devices can complement each other so that multiple correction devices can cover all blade profile segments at different positions along the blade length. In addition, when a wax model for an aero-engine blade only needs to correct one blade profile segment, for example, only blade profile segment one needs to be corrected, a blade correction seat 3 provided on the correction device for the aero-engine blade wax model can also be used to correct the wax model for the aero-engine blade.

[0058] One embodiment of this application, such as Figure 3 and Figure 7 As shown, the first end of the mounting body 31 in the left-right direction is provided with a support block 310, and the first end of the lower straightening block 32 is provided with a push protrusion 320 in the height direction directly opposite the support block 310. The push protrusion 320 is located above the support block 310, and there is a gap between the support block 310 and the push protrusion 320 to form a spacer insertion groove with adjustable spacing. The swing drive mechanism includes: Adjusting pad 9 is detachably embedded in the pad embedding groove. During the process of inserting adjusting pad 9 into the pad embedding groove, the lower side of adjusting pad 9 abuts against the upper side of support block 310, and the upper side of adjusting pad 9 pushes against the lower side of push protrusion 320, causing lower straightening block 32 to swing relative to mounting body 31 in the height direction, and upper straightening block 33 to rotate relative to the swinging lower straightening block 32 in the height direction. When adjusting pad 9 is fully embedded in the pad embedding groove, upper straightening block 33 is placed in compression correction position 1. When adjusting pad 9 is removed from the pad embedding groove, upper straightening block 33 can rotate relative to lower straightening block 32 in the height direction to deviation position 1.

[0059] In this embodiment, as Figure 3 and Figure 7 As shown, in this embodiment, by embedding the adjusting pad 9 into the pad slot between the support block 310 and the push protrusion 320, the lower straightening block 32 swings relative to the mounting body 31 in the height direction under the action of the adjusting pad 9. When the adjusting pad 9 is fully embedded in the pad slot, it is beneficial to place the upper straightening block 33 in the compression and correction position 1, which in turn is beneficial to the inner sidewall of the blade profile section straightening through groove 34 to compress and correct the profile of the blade profile section 1 that is directly opposite it, so as to achieve the correction of the profile of the blade profile section 1 so that the profile of the blade profile section 1 meets the shape required by the design drawings.

[0060] Furthermore, such as Figure 3 , Figure 6 and Figure 7As shown, the installation method of the swing drive mechanism between the tenon lower straightening block 22 and the tenon mounting body 21 in this embodiment is the same as or similar to the installation method of the swing drive mechanism between the lower straightening block 32 and the mounting body 31. The first end of the tenon mounting body 21 in the left-right direction is provided with a tenon support block 210. The first end of the tenon lower straightening block 22 is provided with a tenon pushing protrusion 220 in the height direction, which is directly opposite to the tenon support block 210. The tenon pushing protrusion 220 is located above the tenon support block 210. There is a gap between the tenon support block 210 and the tenon pushing protrusion 220 to form an adjustable pad embedding groove. The adjustable pad 9 is detachably embedded in the pad embedding groove. During the process of inserting the adjusting pad 9 into the groove, the lower side of the adjusting pad 9 abuts against the upper side of the tenon support block 210, and the upper side of the adjusting pad 9 pushes against the lower side of the tenon push-up protrusion 220, causing the tenon lower straightening block 22 to swing relative to the tenon mounting body 21 in the height direction, and the tenon upper straightening block 23 to rotate relative to the swinging tenon lower straightening block 22 in the height direction. When the adjusting pad 9 is fully inserted into the groove, the tenon upper straightening block 23 is placed in the tenon correction position. When the adjusting pad 9 is removed from the groove, the tenon upper straightening block 23 can rotate relative to the tenon lower straightening block 22 in the height direction to the tenon deviation position.

[0061] Furthermore, such as Figure 4 , Figure 5 and Figure 7 As shown, there are multiple sets of adjusting pads 9, and each set of adjusting pads includes multiple adjusting pads 9. The thickness of the multiple adjusting pads 9 in the same set is equal, while the thickness of the multiple adjusting pads 9 in different sets is not equal.

[0062] In this embodiment, as Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, in this embodiment, multiple sets of adjusting pads 9 are provided. The thickness of the multiple adjusting pads 9 in different sets of adjusting pads 9 is not equal. The adjusting pads 9 with different thicknesses adjust the straightening block 32 to swing at different angles relative to the mounting body 31 in the height direction. This is beneficial for the straightening device for the aero-engine blade wax model 8 to select adjusting pads 9 of different thicknesses for straightening according to the contour deformation characteristics of the blade profile segment 1, thereby improving the accuracy and stability of straightening the aero-engine blade wax model 8.

[0063] Furthermore, such as Figure 4 and Figure 5 As shown, the straightening device for aero-engine blade wax models also includes: The shelf 14 is mounted on the base 1 and has a shelf portion for holding multiple adjusting pads 9.

[0064] In this embodiment, as Figure 4 and Figure 5 As shown, in this embodiment, a shelf 14 is provided on the base 1, and the adjustment pad 9 is placed on the shelf 14, which makes it easy to organize and store the adjustment pad 9.

[0065] Furthermore, such as Figure 1 , Figure 4 and Figure 5 As shown, the shelf 14 is provided with a shelf cover plate 13, which is fixed to the base 1 by cover plate fixing screws 15.

[0066] Furthermore, such as Figures 1 to 7 As shown, before the wax model blade is corrected, the contour of the wax model blade body of the aero-engine blade wax model 8 to be corrected is detected by the contour detection device to obtain the contour feature parameters of multiple blade body contour segments of the wax model blade body. The contour feature parameters of the multiple blade profile segments are compared one by one with the multiple standard contour feature parameters to obtain the contour deviation of the multiple blade profile segments. The standard contour feature parameters are the contour feature parameters of multiple blade profile segments of the wax model blade of the standard aero-engine blade wax model 8. The multiple standard contour feature parameters are obtained by pre-detection. Based on multiple contour deviations, the contour correction amounts of multiple blade contour segments are obtained, thereby determining the size of the first preset angle that the swing drive mechanism needs to drive the lower correction block 32 to rotate. An adjustment pad 9 of appropriate thickness is selected based on the first preset angle, which helps to ensure that the lower correction block 32 swings at a suitable angle relative to the mounting body 31 in the height direction. This, in turn, helps to define a suitable blade contour segment correction channel 34 between the arc-shaped groove 321 and the arc-shaped protrusion 331. After correction according to the contour correction amount, the contour characteristic parameters of multiple blade contour segments are within the allowable error range of their corresponding standard contour characteristic parameters. Furthermore, for the contour correction amount of blade contour segment 1, when the swing drive mechanism drives the lower correction block 32 to rotate at the first preset angle, the inner wall of the blade contour segment correction channel 34 compresses the contour of the blade contour segment 1 directly opposite it, causing the deformation of the blade contour segment 1 to equal the contour correction amount. Blade contour segment 1 is one of multiple blade contour segments.

[0067] In this embodiment, as Figures 1 to 7As shown, in this embodiment, a contour detection device is used to detect the contour of the wax model blade of the aero-engine blade wax model 8 to be corrected. The contour feature parameters of multiple detected blade contour segments are compared one-to-one with multiple standard contour feature parameters to obtain the contour deviation of multiple blade contour segments. This is beneficial for identifying the blade contour segments that need to be corrected based on the multiple contour deviations, and for obtaining the contour correction amount of the blade contour segments that currently need to be corrected. This is further beneficial for obtaining the first preset angle size of the swing drive mechanism to drive the lower correction block 32 to swing based on the contour correction amount of the blade contour segments that currently need to be corrected. When the swing drive mechanism drives the lower correction block 32 to swing the first preset angle, the inner wall of the blade contour segment correction groove 34 squeezes the contour of the blade contour segment 1 that is directly opposite it. This is beneficial for making the deformation of the blade contour segment 1 after being squeezed by the inner wall of the blade contour segment correction groove 34 equal to the contour correction amount.

[0068] One embodiment of this application, such as Figure 3 and Figure 7 As shown, the lower side of the adjusting pad 9 forms a lower stop support surface, and the upper side of the adjusting pad 9 is provided with a stepped structure to form an upper stop support surface 1 91 and an upper stop support surface 2 92. The thickness between the upper stop support surface 1 91 and the lower stop support surface is the first thickness, and the thickness between the upper stop support surface 2 92 and the lower stop support surface is the second thickness. The first thickness is greater than the second thickness. An angle mark 911 is provided on the upper stop support surface 91, and an angle mark 921 is provided on the upper stop support surface 92. The angle mark 911 marks the angle at which the adjusting pad 9 can push the lower orthopedic block 32 to swing relative to the mounting body 31 in the height direction when the first thickness is fully embedded in the groove. The angle mark 921 marks the angle at which the adjusting pad 9 can push the lower orthopedic block 32 to swing relative to the mounting body 31 in the height direction when the second thickness is fully embedded in the groove.

[0069] In this embodiment, as Figure 3 and Figure 7As shown, in this embodiment, by adjusting the first thickness and the second thickness of the pad 9 to be different, it is beneficial that the same adjusting pad 9 can make the lower straightening block 32 swing at different angles relative to the mounting body 31 in the height direction, thereby improving the accuracy of straightening the aero-engine blade wax model 8. Furthermore, by providing angle mark 911 on the upper stop support surface 91 and angle mark 921 on the upper stop support surface 92, angle mark 911 and angle mark 921 indicate the angle at which the lower straightening block 32 can swing relative to the mounting body 31 in the height direction, it is more convenient to select the corresponding angle mark 911 or angle mark 921 according to the angle at which the lower straightening block 32 swings relative to the mounting body 31 in the height direction.

[0070] One embodiment of this application, such as Figure 3 As shown, the mounting body 31 has an arc-shaped mounting groove 312 with an upper opening in the front-rear direction, and the lower straightening block 32 has an arc-shaped mounting protrusion 322 on the lower side. The arc-shaped mounting protrusion 322 is housed in the arc-shaped mounting groove 312 and can swing within the arc-shaped mounting groove 312. The mounting body 31 is also provided with an arc-shaped limiting protrusion 313 in the front-rear direction. The arc-shaped limiting protrusion 313 extends into the arc-shaped mounting groove 312. The arc-shaped mounting protrusion 322 is provided with an arc-shaped limiting groove 313 opposite to the arc-shaped limiting protrusion 313. The arc-shaped limiting protrusion 313 extends into the arc-shaped limiting groove 313. The arc-shaped limiting protrusion 313 can limit the angle of swing of the lower orthopedic block 32 relative to the mounting body 31 in the height direction.

[0071] In this embodiment, as Figure 3 As shown, in this embodiment, by housing the arc-shaped mounting protrusion 322 in the arc-shaped mounting groove 312, it is easier for the lower straightening block 32 to swing on the mounting body 31; by extending the arc-shaped limiting protrusion 313 into the arc-shaped mounting groove 312, it is beneficial to limit the swing angle of the lower straightening block 32 on the mounting body 31, thereby helping to avoid damage to the aero-engine blade wax model 8 located in the straightening through groove 34 of the blade profile section by excessive swing angle of the lower straightening block 32 during the swing process.

[0072] One embodiment of this application, such as Figure 3 As shown, the straightening device for aero-engine blade wax models also includes: An auxiliary drive mechanism is installed between the mounting body 31 and the lower orthotic block 32. The lower orthotic block 32 can swing in the height direction under the drive of the auxiliary drive mechanism, and the upper orthotic block 33 can swing in the height direction along with the swing of the lower orthotic block 32. The upper orthotic block 33 can rotate in the height direction relative to the swinging lower orthotic block 32 to have a suitable compression correction position and a deviation position.

[0073] In this embodiment, as Figure 3 As shown, in this embodiment, the lower orthopedic block 32 is driven to swing in the height direction by an auxiliary drive mechanism. This facilitates the adjustment of the thickness of the adjusting pad 9 embedded in the pad embedding groove as needed, thereby adjusting the spacing between the pad embedding groove formed between the support block 310 and the push protrusion 320. This is beneficial for embedding the adjusting pad 9 with a suitable thickness into the pad embedding groove, and also for making the lower side of the adjusting pad 9 abut against the upper side of the support block 310, and for making the upper side of the adjusting pad 9 push against the lower side of the push protrusion 320, thus improving the accuracy of placing the upper orthopedic block 33 in the compression correction position.

[0074] Furthermore, such as Figure 3 As shown, the mounting body 31 is provided with a movable clearance groove 315, which extends horizontally in the left-right direction. The second end of the mounting body 31 is provided with a threaded through hole 316 communicating with the movable clearance groove 315. The mounting body 31 is also provided with a vertical clearance opening 314, which is located above the movable clearance groove 315 and communicates with it. The auxiliary drive mechanism includes: The drive slider 38 is slidably installed in the movable clearance groove 315, and the upper side of the drive slider 38 is provided with a limit slot 382 facing the vertical clearance opening 314. The drive rod 383 is connected to the lower side of the arc-shaped mounting protrusion 322, facing the limiting slot 382, ​​and the lower end of the drive rod 383 extends into the limiting slot 382; The drive screw 384 is threadedly connected to the threaded through hole 316. One end of the drive screw 384 is connected to the drive slider 38, and the other end of the drive screw 384 is provided with an adjustable grip. The adjustable grip is located on the outside of the mounting body 31. The drive slider 38 can slide in the movable clearance groove 315 under the pushing action of the drive screw 384, so that the drive rod 383 extending into the limiting slot 382 drives the lower orthopedic block 32 to swing in the height direction. When the drive slider 38 slides in the movable clearance groove 315, the drive rod 383 can move left and right in the vertical clearance through opening 314.

[0075] In this embodiment, as Figure 3As shown, in this embodiment, the mounting body 31 is provided with a movable clearance groove 315 and a threaded through hole 316 and a vertical clearance opening 314 communicating with the movable clearance groove 315. The driving slider 38 in the movable clearance groove 315 slides in the movable clearance groove 315 under the action of the driving screw 384 threadedly connected to the threaded through hole 316, which is conducive to driving the driving rod 383 located on the limiting slot 382 to move left and right in the vertical clearance opening 314. The driving rod 383 located on the lower side of the arc-shaped mounting protrusion 322 extends into the limiting slot 382 on the driving slider 38, which is conducive to driving the arc-shaped mounting protrusion 322 to swing in the arc-shaped mounting groove 312 when the driving slider 38 slides in the movable clearance groove 315, which is conducive to limiting the angle of swing of the lower orthopedic block 32 on the mounting body 31.

[0076] Furthermore, such as Figure 1 As shown, a baffle 317 is provided on the side of the mounting body 31 facing away from the arc-shaped limiting groove 31 in the front-rear direction. The baffle 317 is installed on the mounting body 31 by screws to prevent impurities from falling into the movable clearance groove 315 and the arc-shaped mounting groove 312 when the straightening device used for the wax model of the aero-engine blade is working. This helps to avoid the swing of the straightening block 32 under the influence of impurities and to prevent impurities from affecting the operation of the auxiliary drive mechanism.

[0077] Furthermore, such as Figure 3 As shown, a screw mounting protrusion 3841 is provided on one end of the drive screw 384, and a screw mounting through groove 381 is provided at the drive slider 38 and the drive screw 384. The screw mounting protrusion 3841 is installed in the screw mounting through groove 381.
