Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of machining, and specifically to an adaptive clamping system for a five-axis linkage blade machining machine tool. Background Art
[0002] Currently, five-axis linkage machining technology is widely used in the aerospace field. As a core component, the machining accuracy of blades directly affects the performance of engines. With the development of blade design towards lightweight and complex shapes, traditional clamping methods are difficult to meet the machining requirements of high precision and high efficiency. The industry generally uses hydraulic fixtures or mechanical positioning fixtures, but there are problems such as time-consuming adjustment and poor adaptability. In recent years, the demand for rapid tool change in flexible manufacturing systems has promoted the development of intelligent fixture technology, but existing solutions still have obvious deficiencies in dynamic stability and multi-specification compatibility.
[0003] Existing hydraulic locking fixtures: fix the blade through the pressure of the oil cylinder, with the advantage of stable clamping force, but the disadvantage is that the positioning reference needs to be recalibrated during adjustment, and it takes more than 30 minutes for each tool change. Mechanical indexing fixtures: use hard limit blocks for positioning, with a simple structure but only suitable for a single blade profile. When changing workpieces, the limit module needs to be manually replaced. Vacuum adsorption fixtures: suitable for thin-walled blades, but unable to withstand large cutting forces and have extremely high requirements for the surface fitting degree. Three-jaw chuck modified fixtures: have strong versatility but the positioning accuracy only reaches ±0.1 mm, unable to meet the micron-level machining requirements of blade root tenon grooves.

A switching rod is fixedly connected to the inner wall of the connecting block. The outer wall of the switching rod is slidably connected inside the base body.
[0015] Working principle: During installation, first place the base body on the machine tool workbench, and then start the first motor. The first motor runs to drive the first screw rod to rotate. As the first screw rod rotates, the connecting sleeve will move up and down under drive. Due to the limiting effect of the limiting plate and the connecting plate, the connecting sleeve will also rotate synchronously during the movement. The movement of the connecting sleeve will drive the rotating ring and the first driving rod to move up and down. The first driving rod slides in the limiting groove inside the guiding block, which will push the fixing block downward until the fixing block is stuck into the installation groove, enabling quick pre-fixing of the base body. Then, pass the anchor bolt through the base body and screw it into the machine tool workbench to complete the secondary fixing, further improving the installation speed. During this entire process, the base body is initially fixed to the machine tool workbench. At the same time, the first motor, the first screw rod, and the connecting sleeve enable the fixing block to be firmly stuck in the installation groove, completing the complete pre-fixing step, playing a role in assisting installation, avoiding repeated auxiliary positioning operations by workers during installation. From the perspective of long-term use, the cooperation between the fixing block and the installation groove can not only achieve pre-fixing but also fix the base body in the left and right directions. Even after long-term use, if the anchor bolt loosens due to vibration, this cooperation structure can still maintain the stability of the base body and prevent it from shifting. During the use process, the function of the guide rail and the clamping frame is to adjust the position of the V-shaped jaws to achieve the adaptive clamping function. During operation, four laser displacement sensors are distributed around the clamping area for detection, which helps to improve the accuracy during product processing; the V-shaped jaws are detachably installed on the electric push rods. If hollow turbine blades are encountered during the use process, the V-shaped jaws can be replaced with arc-shaped jaws for adaptation. The electric push rod array has scalability and can be extended up to twelve groups for the production of ultra-long stator blades. According to actual production requirements, the clamping frame can slide backward out of the guide rail under the limiting action of the guide rail, so as to realize the replacement of the clamping frame; in addition, after starting the motor, it will drive the second screw to rotate on the inner wall of the fixed disk, achieving the rapid installation and disassembly of the V-shaped jaws. At the same time, the electric push rod can be a servo electric cylinder with an IP67 protection level, with a thrust of 3000N and a repeat positioning accuracy of ±5μm. The V-shaped jaws are treated with carburizing and quenching of 20CrMnTi, with a hardness of HRC58-62. The laser sensor is of the KEYENCE LK-H008 type, with a measurement range of ±8mm and a resolution of 0.1μm. When the second screw rotates, it will drive the ejector plate to slide on the inner wall of the fixed disk. The inclined surface of the ejector plate fits with the inclined surface of the adjusting plate. As the ejector plate moves, it will drive the adjusting plate to move leftward. The movement of the adjusting plate will then drive the outer support block to be clamped into the V-shaped jaws under the limiting action of the fixed disk. The outer support block will pull the V-shaped jaws to realize the installation of the V-shaped jaws; During the movement of the outer support block, by adding gaskets, the force for the V-shaped jaws to tighten backward can be further increased, improving the stability after installation and effectively preventing the V-shaped jaws from shaking; when the V-shaped jaws need to be replaced with arc-shaped jaws, only the motor needs to be driven in the reverse direction to drive the ejector plate. When the ejector plate moves backward, the adjusting plate will move downward under the push of the spring, so as to quickly realize the disassembly and replacement of the V-shaped jaws; Start the second motor, which will drive the second driving rod to rotate, and adjust the position of the bidirectional driving gear according to actual use requirements. The second driving rod is square and fits the inner wall shape of the bidirectional driving gear. When the bidirectional driving gear meshes with the third driving rod, the function of convenient blanking can be realized, and the product can be tilted at a certain angle during product processing to make the processing operation more convenient. When the bidirectional driving gear meshes with the double-headed screw, it can drive the clamping frame to move forward or backward. During this process, the chips generated by cutting will be collected by the base body. As the clamping frame moves, the chips will be piled up and concentrated, which not only speeds up the cleaning speed but also facilitates the centralized treatment of waste materials; When driving the third driving rod, it will drive the adjusting curved rod and the adjusting table to rotate under the limiting action of the base body, thereby realizing height adjustment. In the initial state, the hydraulic cylinder drives the connecting block and the switching rod, and the protrusions on both sides of the adjusting table can be taken out from the base body, and then the telescopic bracket is replaced, so that the height of the adjusting table can be adjusted to meet the processing requirements of products with different heights. When the adjusting table is installed on the base body, the switching rod will lock the adjusting table in the default state to further enhance stability; The switching rod has three stages. When entering the first stage, the left switching rod slides to the right to fix the right protrusion. At this time, the adjusting table can be flipped to the right. When entering the third stage, the hydraulic cylinder drives the connecting block to retract, the right side of the switching rod slides out and moves to the left, and the third driving rod drives the adjusting curved rod and the adjusting table to move to the left, tilting the adjusting table to the left. Through these operations, the flipping angle of the adjusting table can be adjusted according to actual usage requirements to adapt to various production environments. After the adjusting table is flipped, it can also assist in loading and unloading operations.
[0016] The present invention provides a self-adaptive clamping system for a five-axis linkage blade processing machine tool. It has the following beneficial effects: 1. In the present invention, by starting the first motor to drive the first screw rod to rotate, driving the connecting sleeve to move up and down and rotate synchronously, and then driving the rotating ring and the first driving rod to move, the rapid pre-fixing of the base body is realized, and then the anchor bolts are passed through the base body and screwed into the machine tool workbench for secondary fixing, achieving the improvement of auxiliary installation, the increase of installation speed, and the avoidance of repeated positioning by workers.
[0017] 2. In the present invention, the second screw rod drives the ejector plate to slide, and the inclined plane structure is used to drive the adjusting plate and the outer support block. During installation, the tightening force can be strengthened by adding gaskets to prevent the V-shaped clamping jaws from shaking. By driving the ejector plate reversely by the motor and pushing the adjusting plate with the spring, the disassembly and replacement of the V-shaped clamping jaws can be quickly completed, significantly improving the convenience and reliability of the fixture adaptation during the processing process and adapting to diverse processing requirements.
[0018] 3. In the present invention, the second motor is started to drive the second driving rod to rotate, the position of the bidirectional driving tooth is adjusted to mesh with the third driving rod or the double-headed screw rod, respectively realizing convenient blanking, inclined processing of products, driving the clamping frame to move, and chip collection and treatment. By driving the adjusting curved rod and the adjusting table by the third driving rod, combined with the hydraulic cylinder, the connecting block and the switching rod, the height adjustment and multi-directional flipping of the adjusting table are realized, having the effects of adapting to various production environments, assisting in loading and unloading, and improving processing efficiency and stability.

Detailed implementation manners
[0021] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0022] Please refer to the attached Figure 1 、attached Figure 2 and attached Figure 3, an adaptive clamping system for a five-axis linkage blade processing machine tool according to an embodiment of the present invention includes a base body 1. The outer wall of the base body 1 is slidably connected to a machine tool workbench 2. An installation groove 3 is provided on the inner wall of the machine tool workbench 2. A connecting plate 4 is fixedly connected to the outer wall of the base body 1. A first motor 5 is fixedly connected to the upper surface of the connecting plate 4. The output end of the first motor 5 is fixedly connected to a first screw rod 6. A connecting sleeve 7 is threadedly connected to the outer wall of the first screw rod 6. A rotating ring 8 is rotatably connected to the inner wall of the connecting sleeve 7. A first driving rod 9 is fixedly connected to the inner wall of the rotating ring 8. A limiting plate 10 is rotatably connected to the outer wall of the first driving rod 9. The outer wall of the limiting plate 10 is rotatably connected to the lower surface of the connecting plate 4. A fixing block 12 is fixedly connected to the outer wall of the first driving rod 9. A guiding block 11 is slidably connected to the outer wall of the fixing block 12. The outer wall of the guiding block 11 is fixedly connected to the outer wall of the connecting plate 4. The outer wall of the fixing block 12 is slidably connected to the outer wall of the guiding block 11. A cutting assembly is arranged on the upper surface of the machine tool workbench 2. The base body 1 and the machine tool workbench 2 are connected by anchor bolts 15. The cutting assembly includes a tool holder 13. The lower surface of the tool holder 13 is fixedly connected to the upper surface of the machine tool workbench 2. A cutting tool 14 is arranged inside the tool holder 13. The cutting tool 14 is used for processing products.
[0023] Specifically, first, the base body 1 is placed on the machine tool workbench 2 for installation. After placing it, the first motor 5 is started to drive the first screw rod 6 to rotate. The rotation of the first screw rod 6 drives the connecting sleeve 7 to move up and down. When the connecting sleeve 7 moves, it rotates under the limitation of the limiting plate 10 and the connecting plate 4. Thus, during use, when the connecting sleeve 7 moves, it drives the rotating ring 8 and the first driving rod 9 to move up and down. During use, when the first driving rod 9 slides in the inner limiting groove of the guiding block 11, the first driving rod 9 drives the fixing block 12 to move downward, so that the fixing block 12 is stuck inside the installation groove 3, thereby achieving the effect of quickly pre-fixing the base body 1 during use. After the base body 1 is fixed during use, the anchor bolt 15 passes through the base body 1 and is inserted into the inside of the machine tool workbench 2. During use, secondary fixing is completed again through 115, further accelerating the installation speed during use. At the same time, the base body 1 and the machine tool workbench 2 play a role of preliminary fixing. And in this process, the first motor 5, the first screw rod 6 and the connecting sleeve 7 are used again to make the fixing block 12 stuck inside the installation groove 3, so as to complete the complete pre-fixing, playing an auxiliary installation effect during use, which can avoid the need for workers to repeatedly assist in positioning during the installation process. At the same time, during long-term use, the cooperation between the fixing block 12 and the installation groove 3 also has the effect of fixing the base body 1 left and right. When the anchor bolt 15 becomes loose due to vibration during long-term use, the stability of the base body 1 can still be maintained, preventing displacement during long-term use.
[0024] Please refer to the attached Figure 1 , the attached Figure 4 and the attached Figure 5 , a guide rail 16 is fixedly connected to the upper surface of the base body 1. A clamping frame 17 is arranged on the outer wall of the guide rail 16. An adaptive clamping module is installed on the inner wall of the clamping frame 17. The adaptive clamping module is composed of an array of six electric push rods 18. The axial arrangement spacing of each group of electric push rods 18 is 50 mm. The end of the electric push rod 18 is equipped with a V-shaped claw 20 to form a clamping area. A pose detection module is arranged in the clamping area. The pose detection module includes four laser displacement sensors symmetrically arranged around the clamping area. A fixed disk 19 is slidably connected to the inner wall of the V-shaped claw 20. The inner wall of the fixed disk 19 is fixedly connected to the front side of the guide rail 16. A motor 21 is fixedly arranged on the inner wall of the fixed disk 19. The output end of the motor 21 is fixedly connected to a second screw rod 22.
[0025] Specifically, during use, the guide rail 16 and the clamping frame 17 are used to adjust the position of the V-shaped claw 20, so as to perform adaptive clamping during use. When in use, when detecting around the clamping area through four laser displacement sensors, the accuracy of the product during processing can be more accurate. At the same time, the V-shaped claw 20 can be detachably installed on the electric push rod 18, so that an arc claw can be replaced during use to adapt to the hollow turbine blade. The array of electric push rods 18 can be extended to twelve groups for producing ultra-long stator blades. During use, according to the actual production requirements, the clamping frame 17 can slide out of the guide rail 16 under the limit of the guide rail 16, so as to achieve the effect of replacing the clamping frame 17. When in use, when starting the motor 21 to drive the second screw rod 22 to rotate on the inner wall of the fixed disk 19, it can achieve the effect of quickly installing and disassembling the V-shaped claw 20; The electric push rod 18 can be selected as a servo electric cylinder with an IP67 protection level, a thrust of 3000 N, a repeat positioning accuracy of ±5 μm. The V-shaped claw is treated by carburizing and quenching of 20CrMnTi, with a hardness of HRC58-62. The laser sensor is selected as the KEYENCEL K-H008 type, with a measurement range of ±8 mm and a resolution of 0.1 μm.
[0026] Please refer to the attached Figure 5, the outer wall of the second screw rod 22 is threadedly connected with an ejection plate 23.

[0027] Specifically, the second screw rod 22 drives the ejection plate 23 to slide on the inner wall of the fixed disk 19, so that the inclined surface of the ejection plate 23 intersects with the inclined surface of the adjusting plate 24, thereby driving the adjusting plate 24 to move leftward by the ejection plate 23, driving the outer support block 25 to be clamped into the inside of the V-shaped claw 20 under the limit of the fixed disk 19, and pulling the V-shaped claw 20 by the outer support block 25. Compared with other methods, in the process of moving, the outer support block 25 can further increase the force for the V-shaped claw 20 to tighten backward by adding gaskets, which can further improve the stability after installation during use and prevent the V-shaped claw 20 from shaking. When it is necessary to replace it with an arc claw, the ejection plate 23 can be reversely driven by the motor 21. When the ejection plate 23 moves backward, the adjusting plate 24 moves downward under the push of the spring 26, so as to quickly install, disassemble and replace the V-shaped claw 20 during use.
[0028] Please refer to the appendix Figure 6 and the appendix Figure 7 , the outer wall of the right side of the base body 1 is fixedly connected with a second motor 27.

[0029] Specifically, by starting the second motor 27 to drive the second driving rod 28 to rotate, the position of the bidirectional driving gear 29 can be adjusted according to the usage requirements at this time. The shape of the second driving rod 28 is square and fits the inner wall shape of the bidirectional driving gear 29. During use, when adjusting the engagement with the third driving rod 31 through the bidirectional driving gear 29, it can facilitate material feeding and tilt the product at an angle during processing for more convenient processing. When the bidirectional driving gear 29 engages with the double-headed screw 30 during use, it can drive the clamping frame 17 to move forward and backward. At the same time, the cut chips will also be collected by the base body 1, and the chips will be piled up and collected when the clamping frame 17 moves. During use, the cleaning speed can be further increased, and the waste can be centrally processed.

[0031] Specifically, when driving the third driving rod 31, the regulating curved rod 32 and the regulating table 33 are driven by the third driving rod 31 to rotate under the limitation of the base body 1, so as to achieve the effect of height adjustment during use. At the same time, when the hydraulic cylinder 34 drives the connecting block 35 and the switching rod 36 in the initial state, the protrusions on both sides of the regulating table 33 are taken out from the base body 1 and replaced with telescopic brackets, which can be used to adjust the height of the regulating table 33 during use, so as to process products with different heights during use. When installed on the base body 1, the regulating table 33 can be locked through the switching rod 36 in the default state, further increasing stability. When the connecting block 35 enters the first stage, the switching rod 36 on the left side slides to the right, so as to fix the protrusion on the right side. During use, the regulating table 33 can be flipped to the right. When entering the third stage, that is, the hydraulic cylinder 34 drives the connecting block 35 to retract, so that the right side of the switching rod 36 slides out and moves to the left. During use, the regulating curved rod 32 and the regulating table 33 are driven by the third driving rod 31 to move to the left, which tilts to the left during use.
