Description

Technical Field

[0001] This invention relates to the field of flexible clamping technology, specifically to a flexible clamping and positioning platform for irregularly shaped precision parts. Background Technology

[0002] The flexible clamping and positioning platform is a tooling device designed based on the principle of flexible adjustment. It is used in the fields of machining, precision assembly, and testing and measurement to clamp and position workpieces of different specifications and shapes. By equipping the platform with adaptively adjustable clamping components, it can adjust the clamping posture and force according to the shape characteristics of the workpiece, effectively solving the problems of rigid clamping that easily damages the workpiece surface and has poor adaptability. It achieves the effects of protecting workpiece accuracy, improving positioning stability, and expanding the applicability of the equipment.

[0003] The flexible clamping and positioning platform for irregularly shaped precision parts is a sub-application of the flexible clamping and positioning platform. It is specifically designed for the structural characteristics and processing requirements of irregularly shaped precision parts. The parts have irregular curved surfaces, complex contours and high-precision dimensional tolerance requirements. Through the coordinated operation of the flexible clamping components, the platform can achieve close fitting and precise positioning of irregular surfaces, meeting the stringent requirements of aerospace, precision instrument and high-end equipment manufacturing for the processing and assembly of irregularly shaped precision parts.

[0004] While existing flexible clamping and positioning platforms for irregularly shaped precision parts achieve initial flexible fit of irregularly shaped workpieces by using liftable clamping rods in conjunction with suction cup structures, thus avoiding scratches on the surface of precision workpieces caused by rigid clamping, they still suffer from insufficient clamping stability in practical applications. The platform's clamping rods are mostly driven by a single power source, and when there are significant differences in the shape of the workpiece, the clamping height can only be adjusted by raising and lowering the entire frame, which cannot provide precise compensation for local fitting gaps. At the same time, the idle clamping rods lack an automatic avoidance mechanism, which can easily interfere with the operator's subsequent work, further affecting the stability and ease of operation of clamping and positioning. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a flexible clamping and positioning platform for irregularly shaped precision parts, which solves the problem of not being able to compensate for local fitting gaps during the clamping process.

A horizontal plate is fixedly connected to the top of the air pump, and a push rod is fixedly connected to the top of the horizontal plate. A fixing plate is fixedly connected to the top of the push rod, and a miniature piezoelectric ceramic is fixedly connected to the top of the fixing plate. A push rod is fixedly connected to the top of the miniature piezoelectric ceramic, and a universal ball is fixedly connected to the top of the push rod. A suction cup is rotatably connected to the top of the universal ball, and a spring-loaded assembly is provided on the inner side of the clamping groove.

[0007] Preferably, the quick-release mechanism includes two sets of upright plates, both sets of upright plates are fixedly connected to the top of the work platform, and each set of upright plates has a buckle fixedly connected to one side. The top of the work platform is provided with multiple cover plates, and each of the multiple cover plates has a slot on both sides. The upright plates are slidably connected to the middle of the slots. One set of upright plates is rotatably connected to a first limiting rod on its left side, and the right end of the first limiting rod penetrates through the upright plate. The other set of upright plates is rotatably connected to a second limiting rod on its right side, and the left end of the second limiting rod penetrates through the upright plate. The second limiting rod is slidably connected to the middle of the first limiting rod. The outer wall of the first limiting rod is provided with a fixing component.

[0008] Preferably, the buffer mechanism includes multiple buffer springs, which are fixedly connected inside the buffer groove. Each of the multiple buffer springs has a movable column fixedly connected to its top. Each of the multiple movable columns has an installation groove on its outer wall. Each of the multiple installation grooves has a magnetic ring fixedly connected inside its interior. Each of the multiple buffer grooves has an electromagnet fixedly connected to its inner wall. Each of the multiple movable columns has a fixedly connected buffer plate on its top. The outer wall of each movable column is provided with a guide component.

[0009] Preferably, the rebound assembly includes two columns, which are fixedly connected to both sides of the clamping groove. The outer walls of the two columns are fitted with reset springs, which are fixedly connected to the top of the horizontal plate.

[0010] Preferably, the fixing component includes two fixing blocks, which are fixedly connected to the outer wall of the second limiting rod. The right end of the first limiting rod has two sliding grooves, and the outer wall of the first limiting rod has two fixing grooves. The sliding grooves are connected to the fixing grooves.

[0011] Preferably, the guiding component includes two guide blocks, which are fixedly connected to both sides of the moving column. The working platform has multiple guide grooves inside, which are connected to the buffer grooves.

[0012] Preferably, a controller is fixedly connected to the front side of the working platform, and the controller is electrically connected to the air pump, the micro piezoelectric ceramic and the electromagnet.

[0013] Preferably, the fixing block is slidably connected to the middle of the sliding groove, and the fixing block engages with the inside of the fixing groove.

[0015] Preferably, the cover plate is fitted to the top of the work platform, and the push rod is slidably connected to the middle of the cover plate.

[0016] This invention provides a flexible clamping and positioning platform for irregularly shaped precision parts. It offers the following advantages: 1. This invention uses a controller to start an air pump to push the horizontal plate upward, which drives push rod one and push rod two to rise and fall synchronously. The universal ball drives the suction cup to rotate adaptively to fit the workpiece. When the clamping is unstable, the micro piezoelectric ceramic drives push rod two to make fine adjustments. The idle push rod one moves downward with the return spring, which realizes flexible and stable clamping of irregular workpieces, and can also free up space for operation and improve the convenience of operation.

[0017] 2. This invention achieves quick disassembly and assembly of the cover plate by rotating and pulling the second limiting rod, causing the fixing block to slide out of the sliding groove and release the limiting position. Pressing the buckle removes the cover plate. During installation, the cover plate is inserted into the vertical plate, and the buckle is initially fixed. Then, the first and second limiting rods are inserted into the vertical plate, and the second limiting rod is rotated to make the fixing block snap into the fixing groove. This facilitates the individual replacement and maintenance of the push rod in the clamping groove, improving the efficiency of equipment maintenance.

[0018] 3. This invention achieves buffer protection for irregularly shaped precision clamped objects during power outages by demagnetizing the electromagnet after it loses its magnetic force and releases its attraction to the magnetic ring. The compressed buffer spring releases its potential energy, pushing the moving column upward and causing the buffer plate to rise and contact the falling clamped object. After the equipment is powered back on, the buffer plate is pressed down, and the electromagnet is energized to attract the magnetic ring and fix the moving column. Attached Figure Description

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figure 1 , Figure 3 and Figure 4 This invention provides a flexible clamping and positioning platform for irregularly shaped precision parts, including a working platform 1. The top of the working platform 1 has a plurality of clamping slots 6 and buffer slots 7 arranged sequentially from front to back to provide space for mechanism installation. The clamping slots 6 are equipped with clamping mechanisms 2 to achieve flexible clamping and positioning of the object to be clamped. The top of the working platform 1 is equipped with a quick-release mechanism 3 to facilitate the disassembly and maintenance of the components of the clamping mechanism 2. The buffer slots 7 are equipped with a buffer mechanism 4 to prevent the object to be clamped from colliding directly with the working platform 1 when the power is off. The clamping mechanism 2 includes an air pump 21, which provides driving power to raise and lower subsequent components. The air pump 21 is fixedly connected to the inner side of the clamping groove 6 to ensure the stability of the air pump 21 during operation. A horizontal plate 22 is fixedly connected to the top of the air pump 21 to receive the power of the air pump 21 and transmit it to the push rod 23. The push rod 23 is fixedly connected to the top of the horizontal plate 22 to drive the fixed plate 24 and subsequent components to rise and fall synchronously. The fixed plate 24 is fixedly connected to the top of the push rod 23 to securely install the micro piezoelectric ceramic 25. The top of the fixed plate 24 is fixedly connected to... There is a miniature piezoelectric ceramic 25, which provides secondary fine-tuning power to compensate for the clamping gap. The top of the miniature piezoelectric ceramic 25 is fixedly connected to a push rod 26, which transmits the power of the miniature piezoelectric ceramic 25 to drive the suction cup 28 to fine-tune. The top of the push rod 26 is fixedly connected to a universal ball 27, which enables the suction cup 28 to rotate at multiple angles. The top of the universal ball 27 is rotatably connected to the suction cup 28, which adheres to the surface of irregular parts to achieve stable adsorption. The inner side of the clamping groove 6 is provided with a spring-loaded component 29, which drives the idle push rod 23 to move down to free up operating space. The rebound assembly 29 includes two columns 291, which guide and limit the return spring 292. The two columns 291 are fixedly connected to both sides of the clamping groove 6 to ensure the installation strength of the columns 291. The return spring 292 is sleeved on the outer wall of the two columns 291 to store elastic potential energy to realize the return of the horizontal plate 22. The two return springs 292 are fixedly connected to the top of the horizontal plate 22 and cooperate with the lifting and lowering of the horizontal plate 22 through their own deformation. Specifically, during use, the object to be clamped is placed on the suction cup 28. The controller 5 starts the air pump 21, which pushes the horizontal plate 22 upward, thereby causing push rod 1 23 and push rod 26 to move upward simultaneously. During this process, the universal ball 27 can drive the suction cup 28 to rotate, so that the suction cup 28 can adaptively conform to the surface of the object to be clamped. If the shape of the object to be clamped is irregular, causing unstable clamping, the micro piezoelectric ceramic 25 can be activated. The micro piezoelectric ceramic 25 further pushes push rod 26 upward, allowing the suction cup 28 to contact the object to be clamped. The fit is tighter, improving the clamping firmness. As the horizontal plate 22 moves upward, it will squeeze the return spring 292 sleeved on the outer wall of the column 291. When the size of the object to be clamped is small and the push rod 23, which does not bear the clamping task, obstructs the operator's operation, the air pump 21 at the bottom of the corresponding push rod 23 is turned off. After the return spring 292 loses pressure, it releases elastic potential energy, pushes the horizontal plate 22 downward, and drives the push rod 23 downward. This can ensure the clamping stability and free up sufficient operating space for the operator.

[0023] Reference Figure 2 , Figure 5 and Figure 6The quick-release mechanism 3 includes two sets of upright plates 31, both of which are fixedly connected to the top of the work platform 1 to ensure the stability of the upright plates 31 during installation. Each of the two sets of upright plates 31 has a buckle 32 fixedly connected to one side, providing initial positioning and fixing of the cover plate 33. Multiple cover plates 33 are provided on the top of the work platform 1 to form a closed protection for the clamping groove 6. Each of the multiple cover plates 33 has a slot 34 on both sides, forming a sliding fit with the upright plates 31. The upright plates 31 are slidably connected to the middle of the slot 34, enabling quick disassembly and assembly of the cover plates 33. One set of upright plates 31 has a limited rotational connection on its left side. Positioning rod 35 serves as the sliding carrier for limiting rod 36. The right end of limiting rod 35 passes through the vertical plate 31 to ensure the limiting accuracy of limiting rod 35. The right side of another set of vertical plates 31 is rotatably connected to limiting rod 36, which drives the fixing block 373 to rotate and slide. The left end of limiting rod 36 passes through the vertical plate 31 and forms a linkage with limiting rod 35. Limiting rod 36 is slidably connected to the middle of limiting rod 35 to realize the extension and retraction adjustment of limiting rod 36. The outer wall of limiting rod 35 is provided with a fixing component 37 to fix the relative position of limiting rod 35 and limiting rod 36. The fixing component 37 includes two fixing blocks 373, which are the core components for limiting and fixing. The two fixing blocks 373 are fixedly connected to the outer wall of the second limiting rod 36 and move synchronously with the second limiting rod 36. The right end of the first limiting rod 35 has two sliding grooves 371 to provide sliding channels for the fixing blocks 373. The outer wall of the first limiting rod 35 has two fixing grooves 372 to form a locking and limiting with the fixing blocks 373. The sliding grooves 371 and the fixing grooves 372 are connected to realize the switching between the sliding and locking states of the fixing blocks 373. The fixing blocks 373 are slidably connected to the middle of the sliding grooves 371 to ensure the smooth sliding of the fixing blocks 373. The fixing blocks 373 are locked inside the fixing grooves 372 to realize the relative fixation of the first limiting rod 35 and the second limiting rod 36. Specifically, when it is necessary to disassemble and replace the push rod 23 inside the clamping groove 6, rotate the limiting rod 36 to drive the fixing block 373 on its outer wall to rotate synchronously. At the same time, pull the limiting rod 36 outward so that the fixing block 373 slides out of the sliding groove 371 of the limiting rod 35, releasing the limiting fixation on the upright plate 31. Then, press the buckle 32 fixed on one side of the upright plate 31, move the cover plate 33 upward and take it out, thereby removing the restriction on the top of the clamping groove 6 and realizing the control of a single push rod 23. For easy assembly and disassembly of the cover plate 33, during installation, align the slots 34 on both sides of the cover plate 33 with the upright plate 31 and insert them into its outer wall, so that the buckle 32 engages with the top of the cover plate 33 for initial fixation. Then, insert the first limiting rod 35 and the second limiting rod 36 into the upright plate 31, and insert the fixing block 373 into the sliding groove 371. Finally, rotate the second limiting rod 36 to drive the fixing block 373 into the fixing groove 372 on the outer wall of the first limiting rod 35 to engage, thereby completing the limiting and fixing of the cover plate 33 and ensuring the overall stability of the mechanism.

[0024] Reference Figure 2 , Figure 7 and Figure 8 The buffer mechanism 4 includes multiple buffer springs 41, which provide elastic buffering force to offset the impact force of the clamped object falling. The multiple buffer springs 41 are fixedly connected inside the buffer groove 7 to ensure the installation stability of the buffer springs 41. The top of each of the multiple buffer springs 41 is fixedly connected to a moving column 42, which transmits the elastic potential energy of the buffer springs 41 to drive the buffer plate 46 to rise and fall. The outer wall of each of the multiple moving columns 42 is provided with an installation groove 43 to provide installation space for the magnet ring 44. The inside of each of the multiple installation grooves 43 is fixedly connected to a magnet ring 44, which cooperates with an electromagnet 45 to fix the moving column 42. The inner wall of each of the multiple buffer grooves 7 is fixedly connected to an electromagnet 45, which controls the position of the moving column 42 by switching the magnetic state by turning the power on and off. The top of each of the multiple moving columns 42 is fixedly connected to the same buffer plate 46 to increase the contact area with the falling clamped object and achieve uniform buffering. The outer wall of the moving column 42 is provided with a guide component 47 to ensure the trajectory accuracy of the moving column 42's rising and falling movement. The guide assembly 47 includes two guide blocks 471, which cooperate with the guide groove 472 to restrict the rotation of the moving column 42. The two guide blocks 471 are fixedly connected to both sides of the moving column 42 and slide synchronously with the moving column 42. The working platform 1 has multiple guide grooves 472 inside to provide sliding channels for the guide blocks 471. The guide grooves 472 are connected to the buffer groove 7 to realize the motion linkage between the guide assembly 47 and the buffer mechanism 4. Specifically, when a sudden power outage causes the clamped object to lose its clamping force and fall, the electromagnet 45 on the inner wall of the buffer groove 7 loses its magnetic force due to the power outage, and the attraction between it and the magnetic ring 44 in the mounting groove 43 of the moving column 42 is released. At this time, the pre-compressed buffer spring 41 releases pressure, pushing the moving column 42 to move upward along the guide groove 472 of the guide assembly 47, which drives the top buffer plate 46 to move upward synchronously and contact the falling clamped object. The elastic deformation of the buffer spring 41 generates a buffering force to prevent the clamped object from being damaged by direct impact. When the power supply is restored, the buffer plate 46 is pressed down to reset, the electromagnet 45 is energized to generate magnetic force, and attracts the magnetic ring 44, thereby fixing the moving column 42 inside the buffer groove 7 for subsequent reuse.

[0025] Reference Figure 2 and Figure 5The front side of the working platform 1 is fixedly connected to the controller 5, which serves as the control center for the various mechanisms of the equipment. The controller 5 is electrically connected to the air pump 21, the micro piezoelectric ceramic 25 and the electromagnet 45 to achieve centralized control of the clamping and buffering actions. The buckle 32 is triangular, which uses the stability of the triangular structure to improve the fixing effect. The buckle 32 fits against the top of the cover plate 33, which plays a preliminary limiting role on the cover plate 33. The cover plate 33 fits against the top of the working platform 1, which forms a closed protection for the internal structure of the working platform 1. The push rod 23 is slidably connected to the middle of the cover plate 33 to ensure the trajectory accuracy of the lifting and lowering movement of the push rod 23. Specifically, the controller 5, fixedly connected to the front of the work platform 1, acts as the core control hub of the equipment through electrical connection with the air pump 21, the miniature piezoelectric ceramic 25, and the electromagnet 45. It realizes centralized control of the lifting and lowering adjustment of the clamping mechanism 2, the clamping stability compensation, and the state switching and reset of the buffer mechanism 4. The triangular buckle 32, with its own structural stability, forms a downward pressure constraint on the cover plate 33 by fitting closely with the top of the cover plate 33, preventing it from loosening or shifting during equipment operation, and providing a preliminary fixing effect for the quick release mechanism 3. The cover plate 33, which fits closely with the top of the work platform 1, can not only form a closed protection for the clamping groove 6 inside the work platform 1 to prevent dust and debris from entering and affecting the movement accuracy of the clamping mechanism 2, but also provide stable sliding support and guidance for the push rod 23, which is slidably connected in the middle, limiting its movement trajectory and preventing deviation. At the same time, it can prevent the push rod 23 from being damaged due to excessive movement.

[0026] Working principle: When using this device, the object to be clamped is placed on the suction cup 28. At this time, the controller 5 starts the air pump 21 to push the horizontal plate 22 upward, so that the push rod 1 23 and push rod 26 move upward. At this time, the universal ball 27 drives the suction cup 28 to rotate and fit the object to be clamped. When the object to be clamped has a large difference in shape and the clamping is unstable, the micro piezoelectric ceramic 25 is activated to push the push rod 26 upward, so that the suction cup 28 fits the object to be clamped more tightly. At the same time, when the horizontal plate 22 moves upward, it will squeeze the return spring 292. When the object to be clamped is small, the push rod 1 23 around the perimeter will obstruct the operator's operation. At this time, the cylinder at the bottom of the push rod 1 23 that is not clamped will close, and the return spring 292 will lose pressure and release elastic potential energy to push the horizontal plate 22 downward, which will drive the push rod 1 23 downward, making the clamping more stable and providing a working space for the operator. When replacement is needed, rotate the second limiting rod 36 to drive the fixing block 373 to rotate forward and pull the second limiting rod 36 to slide the fixing block 373 out of the sliding groove 371 to remove the limiting fixation on the upright plate 31. At this time, press the buckle 32 to move the cover plate 33 upward and remove it, removing the restriction on the top of the clamping groove 6, which makes it convenient to disassemble and replace the single push rod 23. During installation, insert the slot 34 on the cover plate 33 into the outer wall of the upright plate 31, and snap the buckle 32 into the top of the cover plate 33. At the same time, insert the first limiting rod 35 and the second limiting rod 36 into the upright plate 31, and insert the fixing block 373 into the interior of the sliding groove 371. Rotate the second limiting rod 36 to rotate the fixing block 373 into the interior of the fixing groove 372 to limit and fix the cover plate 33. Finally, when the equipment loses power, the clamped object loses its clamping force and moves downward. When the electromagnet 45 loses power and loses its magnetic force, it loses its attraction to the magnet ring 44. At this time, the compressed buffer spring 41 releases pressure and pushes the moving column 42 upward, so that the buffer plate 46 moves upward and contacts the clamped object to generate a buffering force to prevent the clamped object from being damaged when the power is off. Pressing down the buffer plate 46, the electromagnet 45 is energized and attracts the magnet ring 44 to fix the moving column 42 inside the buffer groove 7 for subsequent use.
