Description

Technical Field

[0001] The present invention relates to the technical field of machining tools for aero-engine blades, and particularly to a bed stability system for a machining tool for aero-blades. Background Art

[0002] Aero-blades are important components that play a key role in energy conversion in aero-engines. They are usually made of high-performance materials such as superalloys and titanium alloys. They have a complex shape and extremely high requirements for surface profile accuracy. Through precisely designed curved surfaces and special geometric shapes, when the engine is running, they interact with high-temperature and high-pressure gas, converting the thermal energy of the gas into mechanical energy, driving the engine rotor to rotate at high speed, and providing a powerful propulsion force for the aircraft. Their machining accuracy and quality directly determine the performance, reliability, and fuel economy of aero-engines, and thus affect the flight performance of the entire aircraft.

[0003] A machining tool for aero-blades is a precision device specifically used to manufacture aero-blades, which are key components of aero-engines. Given the complex shape and extremely high accuracy requirements of aero-blades, such machining tools often possess a high degree of precision and multi-axis linkage functions. Among them, a five-axis linkage milling machine is the most commonly used in aero-blade machining. It can achieve complex trajectory movements of the tool in space through the coordinated movements of three linear coordinate axes X, Y, and Z and two rotational coordinate axes A and C, precisely milling the complex profile of the blade to remove excess material, thereby meeting the stringent machining accuracy and surface quality requirements of aero-blades and ensuring that the produced aero-blades can provide reliable guarantee for the stable and efficient operation of aero-engines.

[0004] However, during the machining process of traditional machine tools, when the machining component processes aero-blades, the force generated will cause the machining component to vibrate, thereby driving the overall vibration, which will change the relative position between the tool and the workpiece and affect the machining accuracy. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a bed stability system for a machining tool for aero-blades, which solves the problem that when the machining component processes aero-blades, the force generated will cause the machining component to vibrate, thereby driving the overall vibration, which will change the relative position between the tool and the workpiece and affect the machining accuracy.

[0006] In view of the deficiencies of the prior art, the present invention provides a bed stability system for an aviation blade processing machine tool, including a machine tool. A processing mechanism is provided on the upper surface of the machine tool. A connecting shell is fixedly connected to the outer wall of the machine tool. A driving motor I is fixedly connected to the outer wall of the connecting shell. A forward and reverse lead screw is connected to the output end of the driving motor I. A threaded block is threadedly connected to the outer wall of the forward and reverse lead screw. The forward and reverse lead screw is provided with two sections of reverse threads. A connecting rod is fixedly connected to the upper surface of the threaded block. A fitting plate is fixedly connected to the outer wall of the connecting rod. A guiding column is fixedly connected to the outer wall of the connecting rod. A back plate is slidably connected to the outer wall of the guiding column. The outer wall of the back plate is fixedly connected to the outer wall of the processing mechanism. A clamping mechanism is provided on the outer wall of the machine tool. A rotating mechanism is provided on the outer wall of the machine tool.

[0007] By adopting the above technical solution, when in use, first start the driving motor I as the driving source to drive the forward and reverse lead screw to rotate. Since the forward and reverse lead screw is provided with two sections of reverse threads, the rotation of the forward and reverse lead screw drives the threaded blocks on both sides to move towards the center, thereby driving the connecting rod and the fitting plate to move, so that the outer wall of the fitting plate fits against the outer wall of the processing mechanism, and the outer wall of the guiding column slides into the inner wall of the back plate. Among them, part of the vibration generated during the operation of the processing mechanism by the fitting plate is transmitted to the inside of the connecting shell through the connecting rod and the threaded block, and then transmitted to the inside of the machine tool. Since the machine tool is directly connected to the ground, the force of left and right shaking is dispersed, reducing the amplitude, and the guiding column bears the up and down shaking of the back plate driven by the processing mechanism and is transmitted to the inside of the machine tool, so that the shaking force during the operation of the processing mechanism is dispersed, reducing the effect of shaking. Among them, the clamping mechanism is used to clamp and fix the aviation blade to be processed to prevent it from shifting under the action of the force of the processing mechanism during work. The rotating mechanism is used to rotate the already fixed aviation blade to improve the continuous working effect.

[0008] As a further description of the above technical solution: The outer wall of the forward and reverse lead screw is rotatably connected to the inner wall of the connecting shell. The outer wall of the connecting rod is slidably connected to the outer wall of the connecting shell.

[0009] By adopting the above technical solution, the connecting shell plays a role in supporting and limiting the forward and reverse lead screw to prevent the connecting shell from falling, and ensuring that the forward and reverse lead screw will not move when driven by the driving motor I. Through the sliding connection between the connecting rod and the connecting shell, the part of the connecting rod that conducts force is increased, and the force is transmitted to the inside of the machine tool and the ground to decompose the vibration force.

[0010] As a further description of the above technical solution: The outer wall of the threaded block is slidably connected to the inner wall of the connecting shell. The outer wall of the fitting plate fits against both sides of the outer wall of the processing mechanism.

[0011] By adopting the above technical solution, due to the limitation of the connecting shell, the threaded block can only perform linear motion, thereby driving the threaded blocks on both sides to move towards each other and center, and by attaching the attaching plates to both sides of the outer wall of the processing mechanism, the vibration generated during the operation of the processing mechanism is conducted into the interior of the attaching plates, and then conducted from the attaching plates to the interior of the connecting rod and the connecting shell, enabling the ground to absorb and decompose the force, realizing the function of conducting and dispersing the force.

[0012] As a further description of the above technical solution: Both sides of the lower surface of the threaded block are fixedly connected with a first rotating bracket, the outer wall of the first rotating bracket is rotatably connected with a rotating rod, the inner wall of the rotating rod is rotatably connected with a second rotating bracket, the outer wall of the second rotating bracket is fixedly connected with a force guiding bracket, the outer wall of the force guiding bracket is slidably connected to the outer wall of the machine tool, and the outer wall of the rotating rod is rotatably connected to the inner wall of the connecting shell.

[0013] By adopting the above technical solution, when the threaded block drives the first rotating bracket to move, it will synchronously drive the rotating rod to rotate around the connection part of the rotating rod and the first rotating bracket as the central axis, thereby pushing the second rotating bracket to move downward, and thus synchronously driving the second rotating bracket and the force guiding bracket to move, making the force guiding bracket touch the ground, dispersing the vibration force generated during the operation of the processing mechanism to the ground, and when not in use, retracting the force guiding bracket without delaying the handling.

[0014] As a further description of the above technical solution: The outer wall of the first rotating bracket is slidably connected to the inner wall of the connecting shell, and the outer wall of the force guiding bracket is slidably connected to the outer wall of the connecting shell.

[0015] By adopting the above technical solution, the threaded block is further restricted by the first rotating bracket to prevent the threaded block from self-rotating. Through the direct contact between the force guiding bracket and the connecting shell, the force conducted to the connecting shell is dispersed into the interior of the force guiding bracket and then dispersed to the ground by the force guiding bracket, increasing the area of force conduction and ensuring a more stable effect during operation.

[0016] As a further description of the above technical solution: The processing mechanism includes a housing, the outer wall of the housing is fixedly connected to the outer wall of the machine tool, both sides of the outer wall of the housing are fixedly connected with a first hydraulic cylinder, the output end of the first hydraulic cylinder is fixedly connected with a fixed rod, the outer wall of the fixed rod is fixedly connected with a first slider, a second driving motor is arranged inside the first slider, the output end of the second driving motor is connected with a collar, a third driving motor is fixedly connected to the inner wall of the collar, the output end of the third driving motor is connected with a processing tool, and a limiting plate is fixedly connected to the inner wall of the housing.

[0017] By adopting the above technical solution, the hydraulic cylinder I serving as the driving source is started to drive the fixed rod to move, and then synchronously drive the slider I to move, and then drive the driving motor II inside the slider I to move, thereby driving the collar, the driving motor III and the processing tool to move. When processing is required, the driving motor III is started to drive the processing tool to rotate to process the aviation blade. When facing an irregular shape, by starting the driving of the driving motor II to drive the collar to rotate, and then drive the driving motor III to rotate, and at the same time cooperating with the driving of the hydraulic cylinder I, the processing mechanism can adapt to positions of different shapes, playing the role of improving the processing adaptability.

[0018] As a further description of the above technical solution: The outer wall of the fixed rod is slidably connected to the inner wall of the housing, and the outer wall of the slider I is slidably connected to the inner wall of the housing.

[0019] By adopting the above technical solution, due to the restriction of the fixed rod, when the slider I moves, it can only move vertically up and down. Fixed rods are arranged on both sides, making the slider I more stable when moving.

[0020] As a further description of the above technical solution: The outer wall of the limiting plate is slidably connected to the outer wall of the slider I, and the outer wall of the limiting plate is slidably connected to the outer wall of the fixed rod.

[0021] By adopting the above technical solution, through the restriction of the limiting plate, the movement of the slider I is further restricted during movement, playing the role of making the slider I move smoothly and ensuring that the processing tool is aligned with the part to be processed.

[0022] As a further description of the above technical solution: The clamping mechanism includes a positioning rod. The lower surface of the outer wall of the positioning rod is fixedly connected to the upper surface of the machine tool. A double-headed hydraulic cylinder is arranged inside the positioning rod. Output ends of the double-headed hydraulic cylinder are fixedly connected with sliders II respectively. The outer wall of the slider II is slidably connected to a limiting track. The outer wall of the limiting track is fixedly connected to both sides of the outer wall of the positioning rod.

[0023] By adopting the above technical solution, by starting the double-headed hydraulic cylinder serving as the driving source to drive the two sliders II to move towards the middle relatively, the limiting track restricts the sliders II to only move linearly during movement, and then drives the rotating mechanism to move towards the middle relatively to clamp the aerospace blade, preventing the aerospace blade from being displaced due to the force of the processing mechanism during processing, thereby affecting the processing accuracy.

[0024] As a further description of the above technical solution: The rotating mechanism includes a fixed motor. The outer wall of the fixed motor is fixedly connected to the inner wall of the slider II, and a positioning disk is arranged at the output end of the fixed motor.

[0025] By adopting the above technical solution, according to the change of the processing position, the positioning plate is driven to rotate by starting the fixed motor as a driving source, and then the aerospace blade restricted by the positioning plate is driven to rotate, so that the whole can meet the continuity function of the aerospace blade during processing.

[0026] Working principle: First, start the driving motor 1 connected to the outer wall of the shell, and the driving motor 1 drives the forward and reverse screws to rotate. Since the forward and reverse screws are set with two sections of reverse threads, the rotation of the forward and reverse screws drives the thread blocks on both sides to move synchronously towards each other, thereby driving the connecting rod and the bonding plate to move, so that the outer wall of the bonding plate is bonded to the outer wall of the processing mechanism, and the outer wall of the guide column slides into the inner wall of the back plate. The bonding plate transmits part of the vibration generated during the operation of the processing mechanism to the inside of the connecting shell through the connecting rod and the thread block, and then to the inside of the machine tool. Since the machine tool is directly connected to the ground, the left and right shaking force is dispersed to reduce the amplitude, and the guide column bears the up and down shaking of the back plate driven by the processing mechanism and transmits it to the inside of the machine tool, so that the shaking force of the processing mechanism during operation is dispersed, reducing the shaking, thereby improving the processing accuracy; When the threaded blocks on both sides are driven by the positive and negative screw rods to move synchronously towards each other, the threaded blocks will also drive the rotating bracket 1 to move synchronously, thereby driving the rotating rod to rotate around the part where the rotating rod and the rotating bracket 1 are connected as the central axis, thereby pushing the rotating bracket 2 to move downward, thereby synchronously driving the rotating bracket 2 and the force guide bracket to move, so that the force guide bracket touches the ground when the laminating plate is laminating the processing mechanism, and the vibration force generated by the operation of the processing mechanism is dispersed to the ground. When it is no longer needed, the force guide bracket is retracted without delaying the transportation function; When the bonding plate is bonded to the outer wall of the processing mechanism and the force-guiding bracket touches the ground, the double-headed hydraulic cylinder is started to drive the two sliders on both sides to move relative to each other, and then the two sliders are driven to move relative to each other, and then the rotating mechanism is driven to move toward each other to clamp the aerospace blade, and then the hydraulic cylinder is started to drive the fixed rod to move, and then the slider is driven to move synchronously, and then the driving motor 2 inside the slider is driven to move, thereby driving the ring, the driving motor 3 and the processing knife to move, and after reaching the appropriate position, the driving motor 3 is started to drive the processing knife to rotate, and the aviation blade is processed. When facing irregular shapes, the driving motor 2 is started to drive the ring to rotate, and then the driving motor 3 is driven to rotate, and at the same time, the driving of the hydraulic cylinder 1 is cooperated, so that the processing mechanism can adapt to the positions of different shapes, improve the processing accuracy, and according to the changes in the processing position of the aerospace blade, the fixed motor is started to drive the positioning plate to rotate, and then the aerospace blade is driven to rotate; That is, the machine tool can not only achieve the effect of dispersing the shaking force during the operation of the processing mechanism, reducing shaking, and thus improving the processing accuracy, but also achieve the effect that the guiding force bracket touches the ground while the fitting plate fits the processing mechanism, dispersing the vibration force generated during the operation of the processing mechanism to the ground. When not in use, the guiding force bracket can be retracted without delaying handling. Finally, it can also achieve the effect of enabling the processing mechanism to adapt to different shapes and positions and improving the processing adaptability.

[0027] The present invention provides a bed stability system for an aviation blade processing machine tool, having the following beneficial effects: 1. In the present invention, first, the driving motor 1 is started to drive the positive and negative lead screw to rotate. Through the movement of the threaded block, the connecting rod and the fitting plate are driven to move, so that the outer wall of the fitting plate fits the outer wall of the processing mechanism, and the outer wall of the guiding column slides into the inner wall of the back plate, thereby dispersing the shaking force during the operation of the processing mechanism, reducing shaking, and improving the processing accuracy.

[0028] 2. In the present invention, the threaded block drives the rotating bracket 1 to move, and then drives the rotating rod to move synchronously, and then pushes the rotating bracket 2 to move downward, thereby synchronously driving the rotating bracket 2 and the guiding force bracket to move, so that the guiding force bracket touches the ground while the fitting plate fits the processing mechanism, dispersing the vibration force generated during the operation of the processing mechanism to the ground, enhancing the stability effect. When not in use, the guiding force bracket is retracted without delaying handling.

[0029] 3. In the present invention, by starting the hydraulic cylinder 1 to drive the fixed rod and the slider 1 to move, and cooperating with the operation of the driving motor 2 and the driving motor 3, the effect of enabling the processing mechanism to adapt to different shapes and positions and improving the processing adaptability is achieved.

[0030] 4. In the present invention, through the connection between the connection shell and the machine tool to support and limit the positive and negative lead screw, and cooperating with the sliding connection between the connecting rod and the connection shell, the effect of ensuring the stable drive of the positive and negative lead screw, increasing the force transmission area of the connecting rod, and conducting the force to the inside of the machine tool is achieved.

[0033] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0034] Please refer to the attached Figure 1 - attached Figure 4 , the embodiment of the present invention provides a bed stability system for an aviation blade processing machine tool, including a machine tool 1, a machining mechanism 2 is arranged on the upper surface of the machine tool 1, a connecting shell 3 is fixedly connected to the outer wall of the machine tool 1, a driving motor I 4 is fixedly connected to the outer wall of the connecting shell 3, a positive and negative lead screw 5 is connected to the output end of the driving motor I 4, a threaded block 6 is threadedly connected to the outer wall of the positive and negative lead screw 5, the positive and negative lead screw 5 is provided with two sections of reverse threads, a connecting rod 7 is fixedly connected to the upper surface of the threaded block 6, a fitting plate 8 is fixedly connected to the outer wall of the connecting rod 7, a guide post 9 is fixedly connected to the outer wall of the connecting rod 7, a back plate 10 is slidably connected to the outer wall of the guide post 9, the outer wall of the back plate 10 is fixedly connected to the outer wall of the machining mechanism 2, a clamping mechanism 15 is arranged on the outer wall of the machine tool 1, and a rotating mechanism 16 is arranged on the outer wall of the machine tool 1.

[0035] Specifically, when in use, first start the first driving motor 4 connected to the outer wall of the connection housing 3. The first driving motor 4 drives the left - right screw rod 5 to rotate. Since the left - right screw rod 5 is provided with two sections of reverse threads, the rotation of the left - right screw rod 5 drives the threaded blocks 6 on both sides to rotate synchronously in the opposite direction. And because the threaded blocks 6 are restricted by the connection housing 3, the force that the left - right screw rod 5 drives the threaded blocks 6 to rotate is converted into the force that drives the threaded blocks 6 to move. As a result, the threaded blocks 6 on both sides move towards the center, thereby driving the connecting rod 7 and the fitting plate 8 to move, making the outer wall of the fitting plate 8 fit against the outer wall of the processing mechanism 2, and making the outer wall of the guide post 9 slide into the inner wall of the back plate 10. Among them, part of the vibration generated during the operation of the processing mechanism 2 by the fitting plate 8 is transmitted to the inside of the connection housing 3 through the connecting rod 7 and the threaded block 6, and then transmitted to the inside of the machine tool 1. Since the machine tool 1 is directly connected to the ground, the force of left - right shaking is dispersed, reducing the amplitude. And the guide post 9 bears the up - and - down shaking of the back plate 10 driven by the processing mechanism 2 and transmits it to the inside of the machine tool 1, so that the shaking force during the operation of the processing mechanism 2 is dispersed, reducing the effect of shaking. Among them, the clamping mechanism 15 is used to clamp and fix the aviation blade to be processed to prevent it from shifting under the action of the force of the processing mechanism 2 during work. The rotating mechanism 16 is used to rotate the already fixed aviation blade. Driven by the rotating mechanism 16, the aviation blade can be rotated according to needs during processing, improving the continuous working effect.

[0036] Please refer to Appendix Figure 3 , Appendix Figure 4 and Appendix Figure 5 , the outer wall of the left - right screw rod 5 is rotatably connected to the inner wall of the connection housing 3, and the outer wall of the connecting rod 7 is slidably connected to the outer wall of the connection housing 3.

[0037] Specifically, through the direct connection between the connection housing 3 and the machine tool 1, it plays a role in supporting and limiting the left - right screw rod 5. On the one hand, it prevents the connection housing 3 from falling, and on the other hand, it ensures that the left - right screw rod 5 does not move when driven by the first driving motor 4. Through the sliding connection between the connecting rod 7 and the connection housing 3, the part of the connecting rod 7 that conducts force is increased, and the force can be conducted to the inside of the connection housing 3, and then to the inside of the machine tool 1.

[0038] Please refer to Appendix Figure 2 , Appendix Figure 3 and Appendix Figure 4 , the outer wall of the threaded block 6 is slidably connected to the inner wall of the connection housing 3, and the outer wall of the fitting plate 8 fits against both sides of the outer wall of the processing mechanism 2.

[0039] Specifically, due to the restriction of the connecting shell 3, the threaded block 6 can only perform linear motion and will not rotate on its own due to the rotation of the left - and - right lead screw 5. Furthermore, it drives the threaded blocks 6 on both sides to move towards the center in opposite directions, and through the fitting plates 8, they are attached to both outer sides of the processing mechanism 2. When the processing mechanism 2 is operating, the vibration generated is conducted into the interior of the fitting plates 8, and then from the fitting plates 8 to the interior of the connecting rods 7 and the connecting shell 3, achieving the effect of dispersing the force conduction and reducing the vibration amplitude.

[0040] Please refer to the appendix Figure 2 - appendix Figure 6 On both sides of the lower surface of the threaded block 6, there are fixedly connected rotating brackets one 11. The outer wall of the rotating bracket one 11 is rotationally connected to a rotating rod 12. The inner wall of the rotating rod 12 is rotationally connected to a rotating bracket two 13. The outer wall of the rotating bracket two 13 is fixedly connected to a force - guiding bracket 14. The outer wall of the force - guiding bracket 14 is slidably connected to the outer wall of the machine tool 1, and the outer wall of the rotating rod 12 is rotationally connected to the inner wall of the connecting shell 3.

[0041] Specifically, when the threaded blocks 6 on both sides are driven by the left - and - right lead screw 5 to move towards each other synchronously, the threaded block 6 will also drive the rotating bracket one 11 to move synchronously, and then drive the rotating rod 12 to move synchronously. Since the rotating bracket two 13 connected to the other side of the rotating rod 12 is connected by the force - guiding bracket 14, the rotating rod 12 rotates around the connection part of the rotating rod 12 and the rotating bracket one 11 as the central axis, and then pushes the rotating bracket two 13 to move downward, thus synchronously driving the rotating bracket two 13 and the force - guiding bracket 14 to move, so that the force - guiding bracket 14 touches the ground while the fitting plate 8 is attached to the processing mechanism 2, dispersing the vibration force generated during the operation of the processing mechanism 2 to the ground. When not in use, the force - guiding bracket 14 can be retracted without delaying the handling.

[0042] Please refer to the appendix Figure 5 and appendix Figure 6 The outer wall of the rotating bracket one 11 is slidably connected to the inner wall of the connecting shell 3, and the outer wall of the force - guiding bracket 14 is slidably connected to the outer wall of the connecting shell 3.

[0043] Specifically, by the sliding of the rotating bracket one 11 on the inner wall of the connecting shell 3, the threaded block 6 is further restricted to prevent the threaded block 6 from rotating on its own. Through the direct contact between the force - guiding bracket 14 and the connecting shell 3, the force conducted to the connecting shell 3 is dispersed into the interior of the force - guiding bracket 14, and then dispersed to the ground by the force - guiding bracket 14, increasing the area of force conduction and ensuring a more stable effect during operation.

[0044] Please refer to the appendix Figure 7, the processing mechanism 2 includes a housing 201, the outer wall of the housing 201 is fixedly connected to the outer wall of the machine tool 1, both sides of the outer wall of the housing 201 are fixedly connected with a first hydraulic cylinder 202, the output end of the first hydraulic cylinder 202 is fixedly connected with a fixed rod 203, the outer wall of the fixed rod 203 is fixedly connected with a first slider 204, a second driving motor 205 is arranged inside the first slider 204, the output end of the second driving motor 205 is connected with a collar 206, the inner wall of the collar 206 is fixedly connected with a third driving motor 207, the output end of the third driving motor 207 is connected with a processing tool 208, and a limiting plate 209 is fixedly connected to the inner wall of the housing 201.

[0045] Specifically, start the first hydraulic cylinder 202 to drive the fixed rod 203 to move, and then synchronously drive the first slider 204 to move. The limiting plate 209 therein plays a role in restricting the position of the first slider 204, and then drives the second driving motor 205 inside the first slider 204 to move, thereby driving the collar 206, the third driving motor 207 and the processing tool 208 to move. After reaching the appropriate position, start the third driving motor 207 to drive the processing tool 208 to rotate and process the aviation blade. When facing an irregular shape, by starting the drive of the second driving motor 205 to drive the collar 206 to rotate, and then driving the third driving motor 207 to rotate, and at the same time cooperating with the drive of the first hydraulic cylinder 202, the processing mechanism 2 can adapt to positions of different shapes and play a role in improving the processing adaptability.

[0046] Please refer to the appendix Figure 7 , the outer wall of the fixed rod 203 is slidably connected to the inner wall of the housing 201, and the outer wall of the first slider 204 is slidably connected to the inner wall of the housing 201.

[0047] Specifically, through the restriction of the fixed rod 203, when the first slider 204 moves, it can only move vertically up and down and will not move in other directions on the inner wall of the housing 201. The fixed rods 203 are arranged on both sides, so that the forces on both sides of the first slider 204 during movement are the same, making the first slider 204 move more stably.

[0048] Please refer to the appendix Figure 7 , the outer wall of the limiting plate 209 is slidably connected to the outer wall of the first slider 204, and the outer wall of the limiting plate 209 is slidably connected to the outer wall of the fixed rod 203.

[0049] Specifically, through the restriction of the limiting plate 209, the movement of the first slider 204 is further restricted, making the first slider 204 move smoothly and ensuring that the processing tool 208 is aligned with the part to be processed.

[0050] Please refer to the appendix Figure 8, the clamping mechanism 15 includes a positioning rod 1501. The lower surface of the outer wall of the positioning rod 1501 is fixedly connected to the upper surface of the machine tool 1. A double-headed hydraulic cylinder 1502 is provided inside the positioning rod 1501. Output ends of the double-headed hydraulic cylinder 1502 are fixedly connected with sliders two 1503 respectively. The outer walls of the sliders two 1503 are slidably connected with limiting tracks 1504. The outer walls of the limiting tracks 1504 are fixedly connected to both sides of the outer wall of the positioning rod 1501.

[0051] Specifically, by starting the double-headed hydraulic cylinder 1502 to drive the sliders two 1503 on both sides to move towards the middle. Among them, the limiting track 1504 restricts the sliders two 1503 to move linearly only during movement without deviation, thereby driving the rotating mechanism 16 to move towards the middle relatively to clamp the aerospace blade, preventing the aerospace blade from shifting in position due to the force of the processing mechanism 2 during processing, so as to affect the processing accuracy.
