Description

Technical Field

[0001] This invention relates to the field of battery tray riveting technology, specifically to a flexible riveting fixture. Background Technology

[0002] A battery tray is a container used to store and transport batteries, which are now used more and more widely in various fields, such as consumer electronics and electric vehicles.

[0003] In the battery tray manufacturing process, there are often many parts with the same structure but different shapes, such as the central longitudinal beam, front crossbeam, and central and rear crossbeams of the battery tray. Multiple sets of assembly tooling need to be developed for these parts, increasing costs several times over. The blind rivets for the central longitudinal beam, front crossbeam, and central and rear crossbeams are generally symmetrical and fixed. On-site operators need to bend over to rivet the blind rivets on both sides of the beams, which seriously violates ergonomics and easily causes fatigue. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a flexible riveting fixture that facilitates riveting of different parts on battery tray components and is applicable to battery tray components with different shapes.

[0005] To solve the above-mentioned technical problems, the present invention provides a flexible riveting fixture, including a first support and a second support arranged in parallel, with a worktable disposed between the first support and the second support.

[0006] A first rotating shaft is rotatably mounted on the first bracket, and a turntable and an indexing plate are fixedly mounted on the first rotating shaft. Multiple slots are formed on the outer edge of the indexing plate. An elastic telescopic rod and a driving component are mounted on the first bracket. One end of the elastic telescopic rod is inserted into a slot to restrict the rotation of the first rotating shaft, and the other end of the elastic telescopic rod is connected to the driving component, which controls the elastic telescopic rod to be pulled out of the slot. A second rotating shaft is rotatably mounted on the second bracket, and the second rotating shaft and the first rotating shaft are arranged coaxially.

[0007] The two ends of the workbench are fixedly connected to the first rotating shaft and the second rotating shaft, respectively. Multiple positioning mechanisms are provided on the workbench, and each positioning mechanism is used to fix different battery tray parts.

[0008] This invention, by setting up an indexing plate and an elastic telescopic rod and driving component for positioning the indexing plate, allows the indexing plate and worktable to rotate by rotating the turntable when the elastic telescopic rod is pulled out of the indexing plate's slot using the driving component. This allows the parts fixed on the worktable to rotate to any angle. After rotating to the desired angle, the elastic telescopic rod automatically inserts into the indexing plate's slot under the action of elasticity, thereby fixing the indexing plate and worktable. In addition, by setting multiple sets of positioning mechanisms on the worktable, different battery tray parts can be fixed, reducing the number of tooling fixtures required for processing battery tray parts.

[0009] Furthermore, the first bracket is provided with two first mounting seats, which are arranged below the indexing plate. The two first mounting seats have coaxial sliding holes. The elastic telescopic rod includes a limiting rod and a spring sleeved on the limiting rod. The limiting rod is inserted into the sliding hole and slidably connected to the two first mounting seats. A limiting ring is fixedly provided on the limiting rod and is arranged between the two first mounting seats. The spring is arranged between the limiting ring and one of the first mounting seats, so that the limiting rod is inserted into the slot under the action of the spring.

[0010] The limiting rod of the present invention can always be pressed against the slot of the indexing plate under the action of the spring, thereby achieving the fixation of the slot.

[0011] Furthermore, a second mounting base is provided on the first bracket. The driving component includes a connecting block, a rotating block, a driving rod, and a driven rod. The rotating block is rotatably mounted on the second mounting base. One end of the driven rod is fixedly connected to the rotating block, and the other end of the driven rod is rotatably connected to one end of the connecting block. The other end of the connecting block is rotatably connected to the lower end of the limiting rod. One end of the driving rod is fixedly connected to the rotating block. The driving rod and the driven rod are located on one side of the rotating block.

[0012] This invention places the active rod and the driven rod on one side of the rotating block. When the active rod is pressed down, the driven rod rotates in the same direction as the active rod. The driven rod drives the limiting rod to move downward against the spring force through the connecting block, thereby causing the limiting rod to be pulled out of the indexing plate's slot. When the indexing plate rotates to the required angle, the active rod is released, and the limiting rod can be reinserted into the indexing plate's slot under the action of the spring.

[0013] Furthermore, a foot pedal is provided at the end of the active rod away from the rotating block.

[0014] This invention incorporates a foot pedal, allowing workers to easily fix and rotate the indexing plate by stepping on it, making it convenient to use.

[0015] Furthermore, the positioning mechanism includes a first positioning mechanism, a second positioning mechanism, a third positioning mechanism, a fourth positioning mechanism, a fifth positioning mechanism, and a sixth positioning mechanism arranged along the length of the worktable;

[0016] The first positioning mechanism and the second positioning mechanism are arranged near the two ends of the worktable to fix the middle longitudinal beam of the battery tray.

[0017] The third and fourth positioning mechanisms are arranged between the first and second positioning mechanisms to fix the front crossbeam of the battery tray.

[0018] The fifth positioning mechanism is arranged between the first positioning mechanism and the third positioning mechanism, and the sixth positioning mechanism is arranged between the third positioning mechanism and the fourth positioning mechanism. The fifth and sixth positioning mechanisms are used to fix the middle and rear crossbeams of the battery tray.

[0019] The six positioning mechanisms of this invention are arranged along the length of the worktable, which reduces the width required for the worktable. This ensures that when the operator is positioned on one side of the worktable, the parts remain close to the operator regardless of their rotation, facilitating operation. Since the middle longitudinal beam is the longest and the middle rear and front crossbeams are shorter, the required length of the worktable can be reduced by arranging the first and second positioning mechanisms for fixing the middle longitudinal beam close to both ends of the worktable, and arranging the middle rear and front crossbeams between the first and second positioning mechanisms. However, since the length of the middle longitudinal beam is less than the sum of the lengths of the middle rear and front crossbeams, the third, fourth, fifth, and sixth positioning mechanisms cannot be sequentially arranged between the first and second positioning mechanisms. This invention arranges the fifth positioning mechanism between the first and third positioning mechanisms, and the sixth positioning mechanism between the third and fourth positioning mechanisms, so that only the space between the first and second positioning mechanisms is needed to fix the three types of parts. This worktable is applicable regardless of which of the three types of parts is being processed.

[0020] Furthermore, a first wing plate is provided at one end of the central longitudinal beam, a first slot is provided at the bottom of the end of the central longitudinal beam away from the first wing plate, and a second slot is provided at the bottom of the end of the central longitudinal beam where the first wing plate is provided.

[0021] The first positioning mechanism includes a first support base and a first pressing mechanism. The first support base is provided with a first locking block that cooperates with a first locking slot. The first locking block is used to lock into the first locking slot to longitudinally limit and support the middle longitudinal beam. The first pressing mechanism is arranged on one side of the first support base and is used to press the middle longitudinal beam.

[0022] The second positioning mechanism includes a second limiting block, a second support base, a second clamping block, and a second pressing mechanism. The second support base is provided with a second locking block that cooperates with the second locking slot. The second locking block is used to engage with the second locking slot to longitudinally limit and support the middle longitudinal beam. The second clamping block is used to clamp the middle longitudinal beam from both sides. The second limiting block is arranged on both sides of the second support base. The second limiting block is used to abut against and support the first wing plate, thereby longitudinally limiting and supporting the middle longitudinal beam. The second pressing mechanism is used to press the middle longitudinal beam and abut the first wing plate against the second limiting block.

[0023] This invention utilizes a first flange, a first slot, and a second slot of the longitudinal beam to position and fix the longitudinal beam. The longitudinal beam is initially positioned along its length by engaging a first and a second locking block in the first and second slots, respectively. A second clamping block fixes the longitudinal beam along its thickness. Then, a second limiting block and a second pressing mechanism fix the first flange, and the first and second pressing mechanisms press the top of the longitudinal beam together, thus achieving the fixation of the longitudinal beam.

[0024] Furthermore, the second clamping mechanism includes a second quick clamp, one end of which is provided with a second pressure plate. The second pressure plate is used to press horizontally on the top of the middle longitudinal beam. Second extrusion blocks are provided on both sides of the second pressure plate. The second extrusion blocks are provided with inclined surfaces that cooperate with the first wing plate. When the second pressure plate presses on the top of the middle longitudinal beam, the inclined surfaces of the second extrusion blocks abut against the first wing plate.

[0025] The inclined surface of the second extrusion block of the present invention is interference-fitted with the first wing plate, fixing the first wing plate between the second extrusion block and the second limiting block, while limiting the length and thickness directions of the middle longitudinal beam, thus ensuring the fixing effect of the middle longitudinal beam.

[0026] Furthermore, the first positioning mechanism includes a first limiting plate, which is arranged on the side of the first support away from the second positioning mechanism. The first limiting plate is provided with an inclined guide surface, which is used to guide the middle longitudinal beam.

[0027] The present invention can guide the positioning and fixing of a long longitudinal beam by setting a guide surface, so as to facilitate the first and second locking blocks to be locked into the first and second locking slots.

[0028] Furthermore, a second wing plate is provided at both ends of the front crossbeam, and a first positioning hole and a second positioning hole are respectively opened at the bottom of the front crossbeam near both ends.

[0029] The third positioning mechanism includes a third support base, a third limiting block, a third positioning seat, and a third pressing mechanism. The third support base is used to support one end of the front crossbeam. The third positioning seat is provided with a detachable third positioning pin. The third positioning pin is used to insert into the first positioning hole of the front crossbeam to position the front crossbeam. The third limiting block is arranged on both sides of the third support base to limit the second wing plate at one end of the front crossbeam. The third pressing mechanism is used to press the front crossbeam and press the second wing plate at one end of the front crossbeam against the third limiting block.

[0030] The fourth positioning mechanism includes a fourth support base, a fourth limiting block, a fourth positioning seat, and a fourth pressing mechanism. The fourth support base is used to support the other end of the front crossbeam. The fourth positioning seat is provided with a detachable fourth positioning pin, which is used to be inserted into the second positioning hole of the front crossbeam to position the front crossbeam. The fourth limiting block is arranged on both sides of the fourth support base to limit the second wing plate at the other end of the front crossbeam. The fourth pressing mechanism is used to press the front crossbeam and press the second wing plate at the other end of the front crossbeam against the fourth limiting block.

[0031] This invention utilizes the second wing plate, first positioning hole, and second positioning hole of the front crossbeam to fix the front crossbeam. The front crossbeam is initially fixed by the third and fourth positioning pins. The second wing plate at one end of the front crossbeam is fixed by the third limiting block and the third clamping mechanism, and the second wing plate at the other end of the front crossbeam is fixed by the fourth limiting block and the fourth clamping mechanism, thereby achieving the fixation of the front crossbeam.

[0032] Furthermore, the third clamping mechanism includes a third quick clamp, one end of which is provided with a third pressure plate. The third pressure plate is used to press horizontally on the top of the front crossbeam. Third extrusion blocks are provided on both sides of the third pressure plate. The third extrusion blocks are provided with inclined surfaces that cooperate with the second wing plate. When the third pressure plate presses on the top of the front crossbeam, the inclined surfaces of the third extrusion blocks abut against the second wing plate.

[0033] The inclined surface of the third extrusion block of the present invention is interference-fitted with the second wing plate, fixing the second wing plate between the third extrusion block and the third limiting block, while limiting the length and thickness directions of the front crossbeam, thus ensuring the fixing effect of the front crossbeam.

[0034] Furthermore, a third wing plate is provided at both ends of the middle and rear crossbeam, and a third positioning hole and a fourth positioning hole are respectively opened at the bottom of the middle and rear crossbeam near both ends;

[0035] The fifth positioning mechanism includes a fifth support base, a fifth limiting block, a fifth positioning seat, and a fifth pressing mechanism. The fifth support base is used to support one end of the middle and rear crossbeam. The fifth positioning seat is provided with a detachable fifth positioning pin. The fifth positioning pin is used to insert into the third positioning hole of the middle and rear crossbeam to position the middle and rear crossbeam. The fifth limiting block is arranged on both sides of the fifth support base to limit the third wing plate at one end of the middle and rear crossbeam. The fifth pressing mechanism is used to press the middle and rear crossbeam and press the third wing plate at one end of the middle and rear crossbeam against the fifth limiting block.

[0036] The sixth positioning mechanism includes a sixth support base, a sixth limiting block, a sixth positioning seat, and a sixth pressing mechanism. The sixth support base is used to support the other end of the middle and rear crossbeam. The sixth positioning seat is provided with a detachable sixth positioning pin, which is used to be inserted into the fourth positioning hole of the middle and rear crossbeam to position the middle and rear crossbeam. The sixth limiting block is arranged on both sides of the sixth support base to limit the third wing plate at the other end of the middle and rear crossbeam. The sixth pressing mechanism is used to press the middle and rear crossbeam and press the third wing plate at the other end of the middle and rear crossbeam against the sixth limiting block.

[0037] This invention utilizes the third wing plate, third positioning hole, and fourth positioning hole of the middle and rear crossbeam to fix the middle and rear crossbeam. The front crossbeam is initially fixed using the fifth and sixth positioning pins. The third wing plate at one end of the middle and rear crossbeam is fixed using the fifth limiting block and the fifth clamping mechanism. The third wing plate at the other end of the middle and rear crossbeam is fixed using the sixth limiting block and the sixth clamping mechanism, thereby achieving the fixation of the middle and rear crossbeam.

[0038] Furthermore, both the first and second supports are equipped with rollers at their bottoms.

[0039] The present invention facilitates the movement of the device by incorporating rollers.

[0040] The beneficial effects of this invention are as follows: By setting an indexing plate and an elastic telescopic rod and driving component for positioning the indexing plate, when the driving component controls the elastic telescopic rod to be pulled out of the indexing plate's slot, the indexing plate and worktable can be rotated by rotating the turntable, so that the parts fixed on the worktable can be rotated to any angle. After rotating to the required angle, the elastic telescopic rod will automatically insert into the indexing plate's slot under the action of elastic force, thereby fixing the indexing plate and worktable. In addition, by setting multiple sets of positioning mechanisms on the worktable, different battery tray parts can be fixed, which can reduce the number of tooling fixtures required for processing battery tray parts.

[0069] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0070] like Figure 1 As shown, this embodiment provides a flexible riveting fixture, including a first support 1 and a second support 2 arranged in parallel, with a worktable 3 disposed between the first support 1 and the second support 2.

[0071] like Figure 2 As shown, the first support 1 has a trapezoidal structure. The top of the first support 1 is rotatably mounted on a first rotating shaft 4 via a bearing. A turntable 6 and an indexing plate 7 are fixedly mounted on the first rotating shaft 4. The turntable 6 and the indexing plate 7 are located on both sides of the first support 1. Multiple slots 8 are evenly opened on the outer edge of the indexing plate 7. One end of the first rotating shaft 4 is fixedly connected to one end of the worktable 3.

[0072] Two first mounting seats 9 are bolted to one side of the indexing plate 7 on the first bracket 1. The two first mounting seats 9 are located in the middle of the first bracket 1, below the indexing plate 7. Sliding holes are coaxially formed on the two first mounting seats 9, within which a limiting rod 11 is slidably mounted. A spring 12 is fitted onto the limiting rod 11, and a limiting ring 13 is fixedly mounted on the limiting rod 11. The limiting ring 13 is positioned between the two first mounting seats 9 to prevent the limiting rod 11 from sliding out of the sliding hole. The spring 12 is positioned between the limiting ring 13 and the lower first mounting seat 9. Under the action of the spring 12, the upper end of the limiting rod 11 is inserted into the slot 8 of the indexing plate 7. Protective covers 10 are provided outside the two first mounting seats 9 to protect the limiting rod 11 and the spring 12.

[0073] A second mounting base 14 is provided on one side of the indexing plate 7 of the first bracket 1. The second mounting base 14 is located at the bottom of the first bracket 1. The driving component includes a connecting block 15, a rotating block 16, a driving rod 17, and a driven rod 18. The rotating block 16 is rotatably mounted on the second mounting base 14 via a bearing. The driving rod 17 and the driven rod 18 are fixedly mounted on the side of the rotating block 16 near the limiting rod 11. One end of the driven rod 18 is fixedly connected to the rotating block 16, and the other end of the driven rod 18 is rotatably connected to the connecting block 15. The connecting block 15 is rotatably connected to the lower end of the limiting rod 11. One end of the driving rod 17 is fixedly connected to the rotating block 16 and is arranged parallel to the driven rod 18. The length of the driving rod 17 is greater than that of the driven rod 18. The end of the driving rod 17 away from the rotating block 16 extends outward and is provided with a foot pedal 19.

[0074] like Figure 3 As shown, a second rotating shaft 5 is rotatably mounted on the top of the second support 2. The second rotating shaft 5 and the first rotating shaft 4 are arranged coaxially, and one end of the second rotating shaft 5 is fixedly connected to the other end of the worktable 3.

[0075] Understandably, by pressing the foot pedal 19, the driving rod 17 drives the driven rod 18 to rotate downwards. The driven rod 18 drives the limiting rod 11 to slide downwards and compress the spring 12. At this time, the limiting rod 11 is pulled out from the slot 8 of the indexing plate 7 and no longer restricts the rotation of the indexing plate 7. The indexing plate 7 and the worktable 3 can be rotated by rotating the turntable 6. After rotating to the required angle, the foot pedal 19 is released, and the limiting rod 11 is reinserted into the slot 8 of the indexing plate 7 under the action of the spring 12, restricting the rotation of the indexing plate 7 again.

[0076] like Figure 1 As shown, three sets of positioning mechanisms are set on the workbench 3. Each set of positioning mechanisms is used to fix different battery tray parts. The positioning mechanisms include a first positioning mechanism 20, a second positioning mechanism 26, a third positioning mechanism 37, a fourth positioning mechanism 45, a fifth positioning mechanism 53, and a sixth positioning mechanism 61 arranged along the length of the workbench 3. The six positioning mechanisms are arranged in a row.

[0077] The first positioning mechanism 20 and the second positioning mechanism 26 are arranged near the two ends of the workbench 3 to fix the middle longitudinal beam 69 of the battery tray; the third positioning mechanism 37 and the fourth positioning mechanism 45 are arranged between the first positioning mechanism 20 and the second positioning mechanism 26 to fix the front crossbeam 73 of the battery tray; the fifth positioning mechanism 53 is arranged between the first positioning mechanism 20 and the third positioning mechanism 37, and the sixth positioning mechanism 61 is arranged between the third positioning mechanism 37 and the fourth positioning mechanism 45. The fifth positioning mechanism 53 and the sixth positioning mechanism 61 are used to fix the middle and rear crossbeam 77 of the battery tray.

[0078] like Figure 10 As shown, a first wing plate 70 is provided at one end of the longitudinal beam 69, a first slot 71 is provided at the bottom of the end of the longitudinal beam 69 away from the first wing plate 70, and a second slot 72 is provided at the bottom of the end of the longitudinal beam 69 where the first wing plate 70 is provided.

[0079] like Figure 4 As shown, the first positioning mechanism 20 includes a first support base 21, a first limiting plate 23, and a first pressing mechanism 25. The first support base 21 is provided with a first locking block 22 that cooperates with the first locking slot 71. The first locking block 22 is used to lock into the first locking slot 71 to longitudinally limit and support the central longitudinal beam 69. The first pressing mechanism 25 is arranged on one side of the first support base 21. The first pressing mechanism 25 includes a first quick clamp, which is used to press the central longitudinal beam 69. The first limiting plate 23 is arranged on the side of the first support base 21 away from the second positioning mechanism 26. The first limiting plate 23 is provided with an inclined guide surface 24, which is used to guide the central longitudinal beam 69. The first support base 21, the first limiting plate 23, and the first pressing mechanism 25 are all fixed to the worktable 3 by bolts.

[0080] like Figure 5 As shown, the second positioning mechanism 26 includes a second limiting block 27, a second support base 29, a second clamping block 30, and a second pressing mechanism 32. The second support base 29 is provided with a second locking block 28 that cooperates with the second bayonet 72. The second locking block 28 is used to engage with the second bayonet 72 to longitudinally limit and support the middle longitudinal beam 69. Two second clamping blocks 30 are provided, and the distance between the two second clamping blocks 30 is equal to the thickness of the middle longitudinal beam 69. The second clamping blocks 30 are fixed to the second clamping base 31 of the workbench 3 by bolts. The second clamping blocks 30 are used to clamp the middle longitudinal beam 69 from both sides. The second limiting block 27 is arranged on both sides of the second support base 29. The second limiting block 27 is used to abut against and support the first wing plate 70, thereby longitudinally limiting and supporting the middle longitudinal beam 69. The second pressing mechanism 32 is used to press the middle longitudinal beam 69 and abut the first wing plate 70 against the second limiting block 27.

[0081] The second clamping mechanism 32 includes a second quick clamp 33. A second pressure plate 35 is provided at one end of the second quick clamp 33. The second pressure plate 35 is used to press horizontally on the top of the middle longitudinal beam 69. Second extrusion blocks 36 are provided on both sides of the second pressure plate 35. The second extrusion blocks 36 are provided with inclined surfaces that cooperate with the first wing plate 70. When the second pressure plate 35 presses on the top of the middle longitudinal beam 69, the inclined surfaces of the second extrusion blocks 36 abut against the first wing plate 70.

[0082] like Figure 13 , 14 As shown, a second wing plate 74 is provided at both ends of the front crossbeam 73, and a first positioning hole 75 and a second positioning hole 76 are respectively opened at the bottom of the front crossbeam 73 near both ends.

[0083] like Figure 6As shown, the third positioning mechanism 37 includes a third support base 38, a third limiting block 39, a third positioning seat 40, and a third pressing mechanism 42. The third support base 38 supports one end of the front crossbeam 73. The third positioning seat 40 is provided with a detachable third positioning pin 41, which is inserted into the first positioning hole 75 of the front crossbeam 73 to position the front crossbeam 73. The third limiting block 39 is arranged on both sides of the third support base 38 to limit the second wing plate 74 at one end of the front crossbeam 73. The third pressing mechanism 42... 2. The third clamping mechanism 42 is used to press the front crossbeam 73 and abut the second wing plate 74 at one end of the front crossbeam 73 against the third limiting block 39. The third clamping mechanism 42 includes a third quick clamp, one end of which is provided with a third pressure plate 43. The third pressure plate 43 is used to press horizontally on the top of the front crossbeam 73. Third extrusion blocks 44 are provided on both sides of the third pressure plate 43. The third extrusion blocks 44 are provided with inclined surfaces that cooperate with the second wing plate 74. When the third pressure plate 43 presses on the top of the front crossbeam 73, the inclined surfaces of the third extrusion blocks 44 abut against the second wing plate 74. The third support seat 38, the third limiting block 39, the third positioning seat 40, and the third clamping mechanism 42 are all fixed to the worktable 3 by bolts.
