Description

Technical Field

[0001] The present invention relates to the technical field of curved surface support, and in particular to a support point adaptive component and a flexible adaptive device for multi-point support. Background Art

[0002] In the field of parts support equipment, especially for components with complex curved surfaces, specific tooling is often required for support, which cannot be applied to any component with curved surface features.

[0003] At present, the multi-point support device based on the "multi-point forming" principle has a low degree of automation. Most of them rely on hydraulic cylinders to adjust the height of the support points to form a curved surface identical to the component. The support effect is unstable and limited by the size of the hydraulic cylinder, and is not suitable for supporting small curved components.

[0004] For example, an existing photovoltaic tracker and multi-point flexible support bracket adjusts the angle between the inclined beam and the column by adjusting the length of the push rod, and the push rod still needs to be adjusted manually, which is complicated to operate and has low reliability. Another transmission mechanism for height adjustment and positioning of a multi-point flexible support body uses a worm gear and a worm gear, and is driven by a motor to adjust a surface suitable for the shape of the part, but it cannot automatically adapt to the complex curved surface features of the part, and relies on a motor drive, which consumes energy.

[0005] Therefore, in order to address the problem that existing support devices cannot automatically adapt to complex curved surface features, it is necessary to provide a multi-point flexible support device that can automatically adapt to complex curved surfaces. Summary of the invention

[0060] The structural composition of the support point adjustment component 4 is introduced below, and the structure and principle of the present invention are explained in detail.

[0061] (I) Support point adjustment component 4:

[0062] like Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the support point adjustment assembly 4 includes: an external thread base 41, a first claw support 42, an internal thread sleeve 43, a first pillar 410, a first claw 47, a first square guide rod 414 and a first compression spring 48.

[0063] The upper end of the first support column 410 is fixedly connected to the T-shaped support 411; the lower end of the first support column 410 is provided with a square hole, and the square hole is slidably matched with the first square guide rod 414; a first compression spring 48 is provided in the square hole of the first support column 410, and the first compression spring 48 is located between the first support column 410 and the first square guide rod 414. When the first support column 410 slides downward relative to the first square guide rod 414, the first compression spring 48 is compressed.

[0064] like Figure 5 , Figure 6 , Figure 7 As shown, the outer surface of the first pillar 410 is provided with a plurality of first annular grooves arranged in parallel.

[0065] Specifically, a thread groove 419 is provided on the first claw support 42 .

[0066] Specifically, a first ratchet tooth is provided at one end of the first claw 47, and the first ratchet tooth can be clamped into the first annular clamping groove. A first cylindrical section is provided at the other end of the first claw 47, and the first cylindrical section passes through the first spring positioning block 49 and the thread groove 419 and is slidably installed in the through hole on the internal thread sleeve 43, and the first claw 47 can slide in the horizontal direction relative to the internal thread sleeve 43. A first claw spring 413 is provided between the first spring positioning block 49 and the first ratchet tooth of the first claw 47; the first claw support 42 is fixedly connected to the external thread base 41, and the internal thread sleeve 43 is screwed to the outside of the external thread base 41 through threads.

[0067] Specifically, the lower end of the first square guide rod 414 is fixedly connected to the external thread base 41 .

[0068] Specifically, an externally threaded base 41 with threads on the outside is fixed on the frame 1 , and a thread groove 419 is provided on the first clamping claw support 42 fixedly connected to the externally threaded base 41 . The thread pitch of the thread groove 419 is equal to the thread pitch of the externally threaded base 41 .

[0069] Specifically, through holes arranged in an array and cooperating with the first claw 47 are provided on both sides of the internal threaded sleeve 43 located outside the first claw support 42 .

[0070] Specifically, the internal thread sleeve 43 cooperates with the external thread of the external thread base 41 through the internal thread provided at the bottom.

[0071] Specifically, the first claw 47 can slide radially relative to the internal threaded sleeve 43 ; and the first claw 47 can slide along the thread groove 419 on the first claw support 42 to achieve circumferential rotation of the first claw 47 relative to the first claw support 42 .

[0072] Specifically, Figure 7 As shown, the first pawl spring 413 is located between the first ratchet tooth and the first spring positioning block 49 close to the inner side of the first pawl support 42 .

[0073] Specifically, the first locking pin 415 can move along the axial direction of the locking pin mounting hole on the internal threaded sleeve 43 and the retaining ring 46 .

[0074] Specifically, one end of the T-shaped support 411 is fixedly connected to the first pillar 410 ; the other end of the T-shaped support 411 is provided with a threaded hole, the threaded hole has the same pitch as the thread on the external threaded base 41 , and is threadedly connected to the second pillar 51 through the threaded hole.

[0075] Furthermore, a snap ring 46 is slidably mounted on the outside of the internal threaded sleeve 43; a second gear 44 is mounted on the outside of the internal threaded sleeve 43, and a first thrust spring 45 is arranged between the snap ring 46 and the second gear 44; a first locking pin mounting hole and a second locking pin mounting hole with two axes coinciding are respectively arranged on the internal threaded sleeve 43 and the snap ring 46; the first locking pin 415 is installed in the first locking pin mounting hole and the second locking pin mounting hole. A first locking pin mounting hole cooperating with the first locking pin 415 is arranged on one side of the internal threaded sleeve 43, and a second locking pin mounting hole is arranged on the snap ring 46.

[0076] Specifically, the second gear 44 is provided with a rectangular guide groove, and the internally threaded sleeve 43 is provided with a rectangular guide rail. The second gear 44 is slidably installed on the internally threaded sleeve 43 through the cooperation of the rectangular guide groove and the rectangular guide rail; the second gear 44 and the internally threaded sleeve 43 are fixed in the circumferential direction and can slide relative to each other in the longitudinal direction.

[0077] Specifically, the clamping ring 46 located on the outer side of the internal threaded sleeve 43 is slidably matched with the internal threaded sleeve 43 through a rectangular guide groove provided on the inner side. The clamping ring 46 and the internal threaded sleeve 43 are fixed in the circumferential direction and can slide relative to each other in the longitudinal direction.

[0078] When the first locking pin 415 is pulled out, the internally threaded sleeve 43 and the clamping ring 46 can slide relative to each other, and the internally threaded sleeve 43 can rotate relative to the first claw support 42 .

[0079] In the present invention, when the support plate 412 moves downward under the gravity of the complex curved surface component, the first pillar 410 and the first square guide rod 414 slide relative to each other and compress the first compression spring 48 at the same time; the first pillar 410 moves downward, the first claw 47 slides relative to the first pillar 410, and the first ratchet of the first claw 47 switches to a different first annular groove for engagement.

[0080] In the present invention, when the first ratchet and the first annular groove are not fully engaged, the elastic force of the first claw spring 413 can push the first claw 47 to slide along the thread groove 419, and at the same time, the first claw 47 drives the internal thread sleeve 43 to rotate relative to the external thread base 41; when the first claw 47 slides along the thread groove 419, it can be displaced relative to the axis of the first pillar 410, thereby adjusting the degree of engagement between the first ratchet and the first annular groove.

[0081] In the present invention, the retaining ring 46 can move upward relative to the internal threaded sleeve 43 under the push of the elastic force of the first thrust spring 45, thereby locking the first claw 47, limiting the lateral displacement of the first claw 47 relative to the internal threaded sleeve 43, and preventing the first claw 47 from switching the first annular groove for engagement, thereby limiting the relative displacement of the first claw 47 and the first pillar 410.

[0082] When working:

[0083] The complex curved surface component is above the support plate 412, and the curved surface component, the support plate 412, the T-shaped support 411 and the first pillar 410 are lowered along the guide rail direction of the first square guide rod 414, and the first compression spring 48 is compressed; during the downward movement of the first pillar 410, the first pillar 410 can compress the first claw spring 413 through the first claw 47, and the first claw 47 moves back and forth and retracts in the internal threaded sleeve 43, and then the first claw 47 switches to different first annular grooves for engagement.

[0084] When the curved surface member reaches the lowest point, the first claw 47 may not completely reach the bottom of the circular groove on the first pillar 410 and is not fully engaged therewith, so the first pillar 410 may still fall, that is, the curved surface member may still shake. At this time, the first locking pin 415 is completely removed from the clamping ring 46 and the internal thread sleeve 43, so that the internal thread sleeve 43 can rotate freely relative to the external thread base 41.

[0085] Since the first claw 47 has not completely reached the bottom of the first circular groove on the first pillar 410, the first claw spring 413 is in a compressed state. Under the elastic force of the first claw spring 413, the first claw 47 rotates circumferentially relative to the first claw support 42 along the thread groove 419 on the first claw support 42. When the first claw support 42 slides along the thread groove 419, it can drive the internal thread sleeve 43 to rotate relative to the external thread base 41, and adjust the height of the first claw 47. At the same time, the internal thread sleeve 43 also moves axially relative to the external thread base 41. During the process, the first claw 47 continues to move along the axial direction of the claw mounting hole on the internal thread sleeve 43 under the push of the first claw spring 413, and further engages with the first circular groove until the first claw 47 is completely inserted into the first circular groove.

[0086] Driven by the circumferential movement of the first claw 47, the internal thread sleeve 43 rotates circumferentially relative to the external thread base 41, and at the same time, the second gear 44 rotates circumferentially relative to the external thread base 41. The second gear 44 drives the third gear 56 and the second support 51 to rotate, and can synchronously adjust the degree of engagement between the second claw 518 and the second annular groove.

[0087] When the first locking pin 415 is completely removed from the retaining ring 46, the retaining ring 46 slides upward under the elastic force of the first thrust spring 45; after the first claw 47 is fully inserted into the first annular groove, the retaining ring 46 continues to slide upward under the elastic force of the first thrust spring 45, and completely blocks the claw mounting hole on the internal threaded sleeve 43, so that the symmetrically arranged first claws 47 cannot move away from each other, and can maintain the retaining state of the first pillar 410, thereby maintaining the support stability of the complex curved surface components.

[0088] Furthermore, in order to further achieve the locking effect of the support point adaptive component, the support point adaptive component of the present invention also includes a support point locking component 5; the support point locking component 5 can lock the position of the T-shaped support 411, realize the secondary locking, and reversely position the first claw 47 and the first support column 410 to ensure the stability of the support point adaptive component 3 after the support is completed. Figure 1 , Figure 8 shown.

[0089] like Figure 1 As shown, the support point locking assembly 5 is screwed to the T-shaped support 411 through threads, and is arranged in parallel with the support point adjustment assembly 4. The specific structure of the support point locking assembly 5 is described below.

[0090] (II), support point locking assembly 5:

[0091] like Figure 8 , Fig. 9 , Fig.10, Fig.11 , Fig.12 , Fig.13 and Fig.14 As shown, the supporting point locking device 5 includes: a second support column 51, a second compression spring 52, a second square guide rod 53, a first base 55, a second claw support 510, a second claw 518, a second claw spring 519 and a claw limiting assembly.

[0092] like Fig. 9 As shown, the second pillar 51 is sleeved on the outside of the second square guide rod 53 and can slide relatively; a second compression spring 52 is provided between the second pillar 51 and the second square guide rod 53; the second compression spring 52 is arranged in the square hole inside the second pillar 51; when the support plate 412 and the T-shaped support 411 move downward due to gravity, the second pillar 51 moves downward relative to the second square guide rod 53, thereby compressing the second compression spring 52, and the elastic force of the second compression spring 52 supports the structural member.

[0093] Furthermore, if Figure 8 , Fig. 9 As shown, the first base 55 and the second base 57 are both fixedly connected to the frame 1. The second claw support 510 is sleeved on the outside of the second pillar 51 and the second square guide rod 53; the second claw support 510 is fixedly connected to the first base 55 by bolts; the second square guide rod 53 is rotatably connected to the first base 55 by a first bearing 54. When the second square guide rod 53 rotates, it can drive the second pillar 51 to rotate synchronously, thereby causing the second pillar 51 to move up and down relative to the T-shaped support 411.

[0094] like Fig. 9 , Fig.10 As shown, the upper half of the second support column 51 is provided with an external thread, and the lower half of the second support column 51 is provided with a second annular groove.

[0095] The external thread on the upper half of the second support 51 is screwed to the threaded hole at one end of the T-shaped support 411. When the second support 51 rotates, it can move relative to the T-shaped support 411. The second annular groove on the lower half of the second support 51 is used to engage with the second claw 518 on the second claw support 510.

[0096] Specifically, Fig. 9 , Fig.10 As shown, the lower end of the second pillar 51 is provided with a second circular groove arranged in an array and opening downward. The two sides of the second claw support 510 are provided with four through holes arranged in a symmetrical array and matched with the second claw 518, and the second claw 518 is slidably installed in the through holes on both sides of the second claw support 510.

[0097] like Fig.12As shown, the second claw 518 includes: a second cylindrical section and a second ratchet; the second ratchet can be inserted into the second annular groove in the lower half of the second pillar 51; the second cylindrical section is slidably mounted on the second claw support 510, and the locking groove 523 at the tail cooperates with the claw limit assembly.

[0098] like Fig.10 As shown, the second claw 518 is slidably installed on the second claw support 510, and a second ratchet is provided at the end of the second claw 518, and a second claw spring 519 is provided between the second ratchet and the second claw support 510; specifically, a second spring positioning block 520 is sleeved on the second cylindrical section, and the second claw spring 519 is sleeved on the second cylindrical section and installed between the second spring positioning block 520 and the second ratchet, and the second spring positioning block 520 is pressed against the inner wall of the second claw support 510 under the action of the second claw spring 519.

[0099] Furthermore, a locking groove 523 is provided at the tail of the second claw 518; the claw limiting assembly cooperates with the locking groove 523 to limit the displacement of the second claw 518 relative to the second claw support 510; when the claw limiting assembly locks the second claw 518, the second claw 518 is away from the second pillar 51 and cannot be engaged with the second annular groove. When the claw limiting assembly is unlocked, the second ratchet of the second claw 518 can be engaged with the second annular groove.

[0100] Specifically, the second locking pin 524 is used to unlock the claw limiting assembly; the claw limiting assembly unlocks the second claw 518, and the second claw 518 is clamped into the second annular groove under the elastic force of the second claw spring 519.

[0101] In a specific embodiment of the present invention, Fig.10 , Fig.13 , Fig.14 As shown, the claw limiting assembly includes: an L-shaped support frame 511, a second thrust spring 512, a square locking support 513, two rectangular brackets 516, two parallel T-shaped guide rails 521, two sets of claw locking buckles 514 and an unlocking spring 515.

[0102] Specifically, Fig.10 As shown, the L-shaped bracket 511 is fixedly connected to the second claw support 510 and the first base 55 by bolts; four sliding pillars are arranged at the lower end of the square locking support 513, and are slidingly connected to the L-shaped support bracket 511 through the four sliding pillars; a second thrust spring 512 is arranged between the L-shaped support bracket 511 and the square locking support 513, and the second thrust spring 512 is sleeved on the outside of the sliding pillar. When the second locking pin 524 locks the square locking support 513, the second thrust spring 512 is in a compressed state.

[0103] Specifically, a plurality of L-shaped brackets 511 are provided and distributed in an array around the periphery of the second claw support 510 .

[0104] Specifically, the square locking support 513 is covered on the outside of the second claw support 510, and a T-shaped guide rail 521 is provided on the inner wall surface of the square locking support 513; a T-shaped guide groove 522 is provided on the claw locking buckle 514, and the claw locking buckle 514 is slidably installed on the T-shaped guide rail 521 through the T-shaped guide groove 522. Two groups of claw locking buckles 514 and T-shaped guide rails 521 are symmetrically arranged, and an unlocking spring 515 is arranged between the two groups of claw locking buckles 514; two rectangular brackets 516 are fixedly connected to the two groups of claw locking buckles 514 respectively.

[0105] Specifically, when the second locking pin 524 locks the square locking support 513, the end of the claw locking buckle 514 can be inserted into the locking groove 523 at the tail of the second claw 518 to limit the displacement of the second claw 518; and the unlocking spring 515 is in a compressed state.

[0106] like Fig.13 , Fig.14 As shown, the two rectangular brackets 516 are positioned by two second locking pins 524. The second locking pins 524 pass through the vertical slots 526 on the square locking support 513 and are inserted into the locking pin holes of the rectangular brackets 516, thereby limiting the two rectangular brackets 516 and limiting the displacement of the two sets of claw locking buckles 514. When the second locking pins 524 limit the rectangular brackets 516 and the claw locking buckles 514, the unlocking spring 515 is in a compressed state.

[0107] During implementation, when the second locking pin 524 is pulled out from the locking pin hole of the rectangular bracket 516, the second locking pin 524 releases the limit on the rectangular bracket 516; the two sets of claw locking buckles 514 slide along the T-shaped guide rail 521 and move away from each other under the elastic force of the unlocking spring 515, and the claw locking buckles 514 move out of the locking groove 523 of the second claw 518, releasing the limit on the second claw 518; further, the second claw 518 can be radially displaced relative to the second claw support 510 under the elastic force of the second claw spring 519 and be clamped into the second annular groove in the lower half of the second pillar 51.

[0108] In the present invention, after the second locking pin 524 is moved out of the rectangular bracket 516, the square locking support 513 can be displaced upward under the elastic force of the second thrust spring 512, thereby blocking the second claw 518 and limiting the second claw 518 from moving out of the second annular groove.

[0109] The present invention realizes locking and limiting of the second claw 518, the second pillar 51 and the support plate 412 by providing a square locking support 513, and can stably support the complex curved surface component above when the support plate 412 is fixed in position.

[0110] Furthermore, when the second claw 518 is engaged with the second annular groove, since the height of the second pillar 51 is uncertain, the second ratchet of the second claw 518 may not be completely engaged with the second annular groove, and therefore, it is necessary to adjust the height of the second pillar 51. Specifically, the height of the second pillar 51 can be slightly adjusted by the relative rotation of the second pillar 51 and the T-shaped support 411.

[0111] Furthermore, the second square guide rod 53 is fixedly connected to the third gear 56 by a fixing bolt 59. The fixing bolt 59 passes through the arc groove on the third gear 56 and the first base 55 and is fixedly connected to the second square guide rod 53; when the third gear 56 rotates, the second square guide rod 53 can rotate synchronously with the third gear 56, and then the second square guide rod 53 can drive the second pillar 51 to rotate to adjust the engagement degree between the second annular groove and the second claw 518.

[0112] Furthermore, a second gear 44 is fixedly installed on the outside of the externally threaded base 41; the second gear 44 is meshed with the third gear 56 through the fourth gear 58; the third gear 56 is fixedly connected to the second square guide rod 53 through a fixing bolt 59; the externally threaded base 41 can drive the second square guide rod 53 to rotate synchronously through the second gear 44, the fourth gear 58 and the third gear 56.

[0113] Specifically, the fourth gear 58 is rotatably mounted on the second base 57, and the second base 57 is fixedly mounted on the frame 1. The third gear 56 is rotatably mounted on the first base 55 of the support point locking assembly 5. When the third gear 56 rotates, the second square guide rod 53 can drive the second support column 51 to rotate; when the second support column 51 rotates relative to the T-shaped support 411, it adjusts its longitudinal height, and then can adjust the degree of engagement between the second circular groove and the second ratchet. That is, after supporting the complex curved surface component, the first support column 410 and the second claw 518 remain stationary, and the complete engagement of the two groups of claws and the two groups of circular grooves is adjusted by the synchronous displacement of the first claw 47 and the second support column 51.

[0114] Furthermore, when the first locking pin 415 is removed from the internally threaded sleeve 43 and the retaining ring 46 , the internally threaded sleeve 43 and the retaining ring 46 can be unlocked; when the second locking pin 524 is removed from the square locking support 513 and the rectangular bracket 516 , the square locking support 513 and the rectangular bracket 516 can be unlocked.

[0115] During implementation, the second square guide rod 53 rotates synchronously with the third gear 56, and the third gear 56 rotates synchronously with the second gear 44 and the internally threaded sleeve 43 through the transmission of the fourth gear 58. The two sides of the fourth gear 58 are respectively meshed with the second gear 44 and the third gear 56 for transmission, so that the internally threaded sleeve 43 and the second pillar 51 rotate synchronously. When the internally threaded sleeve 43 rotates to adjust the engagement degree between the first claw 47 and the first annular groove, it can synchronously drive the second pillar 51 to move and adjust the engagement degree between the second claw 518 and the second annular groove, so that the two are fully engaged.

[0116] Specifically, the second thrust springs 512 arranged in a circular array can press the square locking support 513 against the lower end surface of the extension portion of the second claw support 510 .

[0117] Specifically, both sides of the square locking support 513 are provided with through holes arranged in a symmetrical array and cooperating with the second claw 518; before the second claw 518 is unlocked from the claw locking buckle 514, the end of the second claw 518 is set in the through hole, and after the claw locking buckle 514 unlocks the second claw 518, the square locking support 513 moves up to block the second claw 518 on the outside of the second claw support 510, thereby fixing the position of the second claw 518 and preventing it from being displaced.

[0118] Specifically, a through hole is provided in the middle of the rectangular bracket 516, and a second locking pin 524 for locking the rectangular bracket 516 cooperates with the through hole in the middle of the rectangular bracket 516. The two ends of the rectangular bracket 516 are respectively fixedly connected to the two claw locking buckles 514 on the same side; the two claw locking buckles 514 on the same side are a group, or in other words, the two claw locking buckles 514 connected to the same rectangular bracket 516 are a group.

[0119] In a specific embodiment of the present invention, the pitches of the spiral groove 419 on the first claw support 42, the internal thread of the internal thread sleeve 43, and the external thread of the upper half of the second support 51 in the support point adjustment component 4 are all the same. The number of teeth of the second gear 44 and the third gear 56 are equal. Therefore, the distance that the first claw 47 in the support point adjustment component 4 rotates and descends along the spiral groove 419 on the first claw support 42 is equal to the distance that the second support 51 moves downward relative to the T-shaped support 411.

[0120] Specifically, Figure 4 , Figure 5 , Fig. 9 , Fig.10As shown, the cross-sections of the first annular groove and the second annular groove are both right triangles. The direction of the oblique cone surface of the annular groove is its orientation, the direction of the first annular groove is upward, and the direction of the second annular groove is downward. When the first claw 47 rotates and descends along the spiral groove 419, that is, the first claw 47 moves downward relative to the first pillar 410 and the second pillar 51 moves upward relative to the second claw 518, the first claw 47 can be fully engaged with the first annular groove and the second claw 518 can be fully engaged with the second annular groove.

[0121] When working:

[0122] The second claw 518 in the support point locking assembly 5 is on the same horizontal plane as the first claw 47 in the support point adjustment assembly 4, and by adjusting the relative position of the second pillar 51 and the T-shaped support 411, the annular groove on the second pillar 51 is made flush with the annular groove on the first pillar 410; when the curved surface component is placed above the T-shaped support 411, the T-shaped support 411 drives the first pillar 410 and the second pillar 51 to descend together, and the first compression spring 48 and the second compression spring 52 are compressed.

[0123] When the second locking pin 524 moves out of the through hole on the rectangular bracket 516, the two rectangular brackets 516 move away from each other under the elastic force of the unlocking spring 515, driving the two sets of claw locking buckles 514 to move away from each other, and the claw locking buckle 514 moves out of the locking groove 523 in the middle section of the second claw 518, unlocking the second claw 518; after the second claw 518 is unlocked, it can be displaced in the radial direction of the second claw support 510 under the elastic force of the second claw spring 519, that is, approach the second pillar 51, and be locked into the annular groove on the second pillar 51.

[0124] When the internal threaded sleeve 43 rotates, the second gear 44 is driven to rotate, and the second gear 44 drives the third gear 56 to rotate through the fourth gear 58 .

[0125] The third gear 56 drives the second square guide rod 53 fixedly connected to it to rotate through the fixing bolt 59, and the second square guide rod 53 drives the second pillar 51 matched with it to rotate circumferentially; when the second pillar 51 rotates relative to the T-shaped support 411, it can adjust the alignment degree of the second claw 518 and the second circular groove of the second pillar 51 relative to the T-shaped support 411, so that the second claw 518 is fully engaged with the second circular groove.

[0126] When the first locking pin 415 is pulled out, the snap ring 46 is unlocked. The snap ring 46 moves upward under the elastic force of the first thrust spring 45 to block the first claw 47. After the first claw 47 cannot move, the first pillar 410 cannot move either. After the second locking pin 524 is removed from the through hole on the rectangular bracket 516, the square locking support 513 moves upward under the elastic force of the second thrust spring 512 until it touches the second claw support 510 and stops moving upward. The square locking support 513 also blocks the two ends of the second claws 518 on both sides of the second pillar 51, so that the second claws 518 arranged in a symmetrical array cannot move away from each other. The second pillar 51 cannot move up and down under the locking of the second claws 518 on both sides.

[0127] When the vertical position of the second pillar 51 is fixed, the second pillar 51 cannot rotate relative to the T-shaped support 411. When the second pillar 51 cannot move downward and rotate, the second square guide rod 53, the third gear 56, the fourth gear 58, the second gear 44, and the internal threaded sleeve 43 cannot rotate; when the internal threaded sleeve 43 cannot rotate, the first claw 47 cannot slide along the spiral groove on the first claw support 42, that is, it cannot continue to descend. When the first claw 47 cannot descend, the first pillar 410 and the T-shaped support 411 fixedly connected thereto cannot continue to descend, and the entire support point position adaptive component 3 is completely locked. In other words, by locking the second pillar 51 with the square locking support 513 and the second claw 518, the reverse locking of the first pillar 410 is achieved, ensuring the overall stability of the support point position adaptive component 3.

[0128] Example 2

[0129] A specific embodiment of the present invention, as Fig.15 As shown, a flexible adaptive device for realizing multi-point support of a curved surface component is provided, comprising: a frame 1, a gear transmission mechanism 2 and the support point adaptive component 3 in Example 1; a plurality of groups of the support point adaptive components 3 are arranged in an array on the frame 1, and the gear transmission mechanism 2 is connected to the first locking pin 415 and the second locking pin 524, so as to drive the first locking pin 415 and the second locking pin 524 to move.

[0130] In a specific implementation manner of the present invention, the gear transmission mechanism 2 can drive the first locking pin 415 and the second locking pin 524 to move synchronously, thereby realizing synchronous unlocking of the first locking pin 415 and the second locking pin 524 .

[0131] like Figure 2 , Figure 3 , Fig.15 , Fig.16As shown, the gear transmission mechanism 2 includes: a first rack 211, a first gear 212, a gear support 213, a sliding rod 214, a first connecting rod 416, a second connecting rod 417, a second rack 418, a first fixed bracket 517 and a second fixed bracket 525.

[0132] Specifically, two gear supports 213 are symmetrically arranged on the frame 1; the first rack 211 is slidably mounted above the gear support 213; the first gear 212 is rotatably mounted above the gear support 213. Multiple first gears 212 are arranged in an array, and the first rack 211 is meshed with one side of the first gear 212; the second rack 418 is parallel to the first rack 211 and meshed with the other side of the first gear 212. When the first rack 211 slides along the gear support 213, it can drive multiple second racks 418 to move synchronously.

[0133] Furthermore, a slide bar 214 perpendicular to the second rack 418 is provided on the side of the gear support 213. One end of the first locking pin 415 is inserted into the first locking pin mounting hole, and the other end is provided with a slide bar mounting hole, and the slide bar 214 is slidably mounted in the slide bar mounting hole; the slide bar 214 is used to limit the displacement direction of the first locking pin 415.

[0134] Specifically, one end of the first connecting rod 416 is hingedly connected to the second rack 418 through a first pin; a U-shaped groove is provided on the second rack 418, and one end of the second connecting rod 417 is slidingly engaged with the U-shaped groove through a second pin; the other end of the first connecting rod 416 and the other end of the second connecting rod 417 are both hingedly connected to the first locking pin 415.

[0135] The first connecting rod 416 , the second connecting rod 417 and the second rack 418 form a triangular structure. When the second rack 418 is displaced, it can drive the first locking pin 415 to displace linearly, and the displacement direction of the first locking pin 415 is perpendicular to the second rack 418 .

[0136] Specifically, when the second rack 418 is displaced, the second pin slides in the U-shaped groove, thereby driving the angle between the first connecting rod 416, the second connecting rod 417 and the second rack 418 to change, and then the first locking pin 415 at the other end is pulled to move through the first connecting rod 416 and the second connecting rod 417. That is, when the second pin slides in the U-shaped groove, the first locking pin 415 moves closer to or away from the support point position adjustment component 4. At the same time, the first pin and the second pin drive the first fixing bracket 517 and the second fixing bracket 525 to move closer to or away from each other.

[0137] Specifically, the first fixed bracket 517 and the second fixed bracket 525 are parallel to each other; a group of second locking pins 524 are fixedly installed at one end of the first fixed bracket 517, and the other end is fixedly connected to the first pin; another group of second locking pins 524 are fixedly installed at one end of the second fixed bracket 525, and the other end is fixedly connected to the second pin. When the second rack 418 moves, the first pin and the second pin move away from each other, thereby driving the first fixed bracket 517 and the second fixed bracket 525 to move away from each other, thereby causing the second locking pins 524 to unlock the support point locking assembly 5.

[0138] Furthermore, the number of the first gears 212 and the second racks 418 is the same as the number of the support point position adaptive components 3 .

[0139] Further, when the first locking pin 415 is displaced toward the second rack 418, the first locking pin 415 is pulled out from the snap ring 46 and the internally threaded sleeve 43, unlocking the snap ring 46 and the internally threaded sleeve 43 of the support point adjustment assembly 4. When the first fixed bracket 517 and the second fixed bracket 525 move away from each other, the second locking pin 524 can be pulled out from the rectangular bracket 516, unlocking the rectangular bracket 516 in the support point locking assembly 5.

[0140] During operation, this embodiment pushes the symmetrically arranged first racks 211 on both sides to move linearly relative to the gear support 213; then the multiple first gears 212 drive the multiple second racks 418 to move. The linear movement of the second rack 418 drives the first connecting rod 416 hinged to the second rack 418 to move in a plane, and the end of the second connecting rod 417 slides along the U-shaped groove on the second rack 418. The ends of the first connecting rod 416 and the second connecting rod 417 move away from each other, driving the first locking pin 415 to slide along the sliding rod 214 and move out of the clamping ring 46 and the internal threaded sleeve 43. When the multiple second racks 418 are displaced synchronously, they can synchronously drive the multiple first locking pins 415 to move out of the multiple support point adjustment components 4 synchronously.

[0141] At the same time, the first fixed bracket 517 and the second fixed bracket 525 move away from each other following the movement of the first connecting rod 416 and the second connecting rod 417, so that the second locking pin 524 moves out of the support point locking assembly 5. In other words, by pushing the first rack 211 to slide relative to the gear support 213, the first locking pin 415 and the second locking pin 524 can be driven to respectively unlock the support point adjustment assembly 4 and the support point locking assembly 5. After the support point adjustment assembly 4 and the support point locking assembly 5 are unlocked, the engagement degree of the claw and the annular groove can be automatically adjusted to achieve complete engagement.

[0142] Compared with the prior art, the technical solution provided by the present invention has at least one of the following beneficial effects:

[0143] 1. The flexible adaptive device for realizing multi-point support of curved surface components of the present invention utilizes the support principle of "multiple points form a surface" and can realize stable support of any component with complex curved surface features without any power source.

[0144] 2. The support point adaptive component of the present invention can effectively avoid the stability of the flexible support structure and the shaking of the structural parts through the locking cooperation of the movable claws and the pillars, thereby ensuring the stability of complex curved surface components during the processing, and playing a positive role in improving the processing accuracy of parts.

[0145] 3. The support plate 412, T-shaped support 411, first pillar 410 and second pillar 51 in the multiple support point adaptive components 3 of the present invention have different descending heights, but through the engagement of the first claw 47 and the second claw 518 with the annular grooves of the first pillar 410 and the second pillar 518 and the locking of the first claw 47 and the second claw 518 by the snap ring 46 and the square locking support 513, the first pillar 410 and the second pillar 51 can be completely locked at any position, so that the curved surface component cannot continue to fall, thereby achieving stepless locking.

[0146] 4. After the first locking pin 415 of the support point adaptive component of the present invention is unlocked, the first claw spring 413 pushes the first claw 47 to slide in the spiral groove 419, thereby driving the internal threaded sleeve 43 to rotate, and the first claw 47 slides in the spiral groove 419 to adjust its own height, so that the first claw 47 is fully engaged with the first annular groove.

[0147] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
