Description

Technical Field

[0001] This utility model relates to the field of battery side panel testing technology, specifically a tooling for testing the side panels of new energy vehicle batteries. Background Technology

[0002] With the booming development of the new energy vehicle industry, the quality and safety of batteries, as the core components of new energy vehicles, have received increasing attention. As an important part of the battery pack, the battery side plate not only bears the task of protecting the battery cells, but also directly relates to the sealing performance, structural strength and overall performance of the battery pack. Therefore, the testing of the battery side plate is particularly important.

[0003] Currently, most existing testing equipment can only inspect one side of the battery side panel. However, battery side panel inspection usually involves more than one side, as both sides may have defects that affect battery performance and safety, such as surface scratches, cracks, corrosion, and uneven coating. Inspecting only one side and omitting the other makes it impossible to fully assess the quality of the battery side panel. Therefore, after completing the inspection of one side of the battery side panel, existing testing equipment requires manual flipping of the battery side panel to inspect the other side. Frequent manual flipping, especially under long-term and large-volume testing conditions, increases operator fatigue, thereby affecting work efficiency and quality.

[0004] Therefore, this utility model provides a tooling for testing the side panels of new energy vehicle batteries to solve the above problems. Utility Model Content

A motor A is fixedly installed on the inner side of the card seat. The output shaft of the motor A passes through the inner wall of one of the support plates and is fixedly connected to a lead screw. One end of the lead screw is rotatably connected to the outer side of the other support plate. The outer side of the lead screw is threadedly connected to the inner side of the support frame. The inner side of the bottom end of the support frame is slidably connected to the outer side of the connecting rod. The protrusion on the inner side of the bottom end of the support frame matches the inner side of the limiting groove.

[0012] As a preferred technical solution of this application, two clamping seats are symmetrically arranged on the inner side of the mounting frame, and two support members are fixed on both sides of the two clamping seats. A motor B is fixedly installed on the outer side of the mounting frame. The output shaft of the motor B passes through the inner side of the mounting frame and is fixedly connected to a double-segment screw. One end of the double-segment screw is rotatably connected to the inner side of the mounting frame. The outer edge of the double-segment screw is threadedly connected to the inner side of two of the support members, while the inner sides of the other two support members are slidably connected to a limit rod. Both ends of the limit rod are fixedly connected to the inner side of the mounting frame.

[0016] (III) Beneficial Effects

[0017] 1. When the connecting rod enters the spiral part from the straight part of the limiting groove through the protrusion on the inner side of the bottom of the support frame, the connecting rod is pressed by the protrusion through the spiral part of the limiting groove, thereby driving the drive gear to rotate. The drive gear drives the two screws to rotate through the two driven gears. At this time, the rotation direction of the worm is opposite to that of the one-way bearing, so that when the worm meshes with the rotating gear, the rotating gear can drive the mounting frame to flip through the connecting column. The mounting frame drives the battery side plate fixed by the clamping plate to flip synchronously, exposing the other side. Therefore, there is no need for manual operation to flip it, thereby shortening the inspection cycle and improving the efficiency of large-scale production. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 ,and Figure 5 As shown, the purpose of this embodiment is to provide a testing fixture, including a workbench 1, a support frame 2, and a testing head 201 fixedly installed at both ends of the support frame 2. A protrusion is provided on the inner side of the bottom end of the support frame 2. The workbench 1 is characterized by having two symmetrically opened mounting slots A101, and a mounting slot B102 is opened on the outer side of the workbench 1 between the two mounting slots A101.

[0030] The inner side of each of the two mounting slots A101 is provided with a mounting frame 3, and the two sides of the mounting frame 3 are fixedly connected with a connecting post 301. The ends of the connecting posts 301 are rotatably connected to the inner side of the mounting slot A101, and one of the connecting posts 301 is provided with a one-way bearing 3011 on the outer side. The one-way bearing 3011 is provided with a rotating gear 302 on the outer side.

[0031] A connecting rod 4 is rotatably connected to the inner side of the mounting groove B102. A limiting groove 401 is opened on the outer side of the connecting rod 4. A drive gear 5 is fixedly connected to one end of the connecting rod 4, and one end of the drive gear 5 is rotatably connected to the inner side of the mounting groove B102. Two driven gears 501 are symmetrically meshed on the outer side of the drive gear 5, and the ends of the two driven gears 501 respectively penetrate into the interior of the two mounting grooves A101 and are fixedly connected to worm gears 502. One end of each worm gear 502 is rotatably connected to the inner side of the mounting groove A101, and the outer side of each worm gear 502 is meshed with the teeth of the rotating gear 302.

[0032] Two support plates 6 are symmetrically fixedly connected to the upper surface of the workbench 1. A card holder 7 is fixedly installed on the upper surface of the workbench 1 near the outer side of one of the supports. A motor A701 is fixedly installed on the inner side of the card holder 7. The output shaft of the motor A701 passes through the inner wall of one of the support plates 6 and is fixedly connected to a lead screw 702. One end of the lead screw 702 is rotatably connected to the outer side of the other support plate 6. The outer side of the lead screw 702 is threadedly connected to the inner side of the support frame 2. The inner side of the bottom end of the support frame 2 is slidably connected to the outer side of the connecting rod 4. The protrusion on the inner side of the bottom end of the support frame 2 matches the inner side of the limiting groove 401.

[0033] In this embodiment, by starting the motor A701, the lead screw 702 is rotated. When the lead screw 702 rotates, it engages with the support frame 2 via a threaded connection, causing the support frame 2 to drive the detection head 201 to move synchronously along the outer edge of the lead screw 702. The moving detection head 201 can detect different positions on the battery side panel surface. While the support frame 2 moves along the lead screw 702, its bottom end is limited by the connecting rod 4, ensuring stability during movement. Simultaneously, the protrusion on the inner side of the bottom end of the support frame 2 engages with the inner side of the limiting groove 401. When the support frame 2 drives the protrusion to move within the linear range of the limiting groove 401, the connecting rod 4 remains unaffected. When the support frame 2 drives the protrusion into the spiral range of the limiting groove 401, the connecting rod 4 is pressed by the protrusion through the spiral portion of the limiting groove 401, causing the connecting rod 4 to drive the drive gear 5 to rotate. The rotation of the drive gear 5, in turn, drives the two screws through the two driven gears 501. When the worm gear 502 rotates, its rotation direction is opposite to that of the one-way bearing 3011. This allows the worm gear 502 to mesh with the rotating gear 302, which in turn drives the mounting frame 3 to flip via the connecting column 301. Simultaneously, the mounting frame 3 flips, causing the battery side plate held and fixed by the clamping plate 10 to flip as well, thus exposing the other side of the battery side plate. This eliminates the need for manual or additional complex operations to flip the battery side plate, enabling continuous inspection and significantly shortening the inspection cycle. In large-scale production, this can significantly improve production efficiency. When the protrusion of the support frame 2 moves from the spiral end of the limiting groove 401 to the straight end, the connecting rod 4 rotates in the other direction, causing the worm gear 502 to drive the rotating gear 302 to move synchronously in the other direction. At this time, the rotation direction of the worm gear 502 is consistent with that of the one-way bearing 3011, ensuring that the worm gear 502 can only drive the rotating gear 302 to rotate along the outside of the connecting column 301, thus preventing the mounting frame 3 from being affected.

[0034] In this embodiment, as Figure 6 and Figure 7 As shown, two clamping seats 8 are symmetrically arranged on the inner side of the mounting frame 3. Two support members 801 are fixed on both sides of the two clamping seats 8. Motors B802 are fixedly installed on the outer side of the mounting frame 3. The output shaft of the motor B802 passes through the inner side of the mounting frame 3 and is fixedly connected to a double-segment screw 803. One end of the double-segment screw 803 is rotatably connected to the inner side of the mounting frame 3. The outer edge of the double-segment screw 803 is threadedly connected to the inner side of two of the support members 801 respectively. A limit rod 804 is slidably connected between the inner sides of the other two support members 801. Both ends of the limit rod 804 are fixedly connected to the inner side of the mounting frame 3.

[0035] Both sides of the clamping seat 8 are provided with sliding grooves 9, and the inner sides of the two sliding grooves 9 are slidably connected with clamping plates 10. Two movable grooves 11 are symmetrically provided on the outer sides of the clamping plates 10. Movable plates 12 are slidably connected on the inner sides of the two movable grooves 11, and support rods 13 are slidably connected between the inner walls of each pair of movable plates 12.

[0036] A hinge seat 14 is fixedly connected to one side of the clamping seat 8. An adjusting plate 15 is hinged to both ends of the hinge seat 14. A hinge member 16 is hinged to the end of the adjusting plate 15. The bottom end of the hinge member 16 is fixedly connected to the outside of the movable plate 12.

[0037] Both sides of the hinge 16 are fixedly connected to limit members 17, and a limit post 18 is connected between the inner walls of every two limit members 17. Both ends of the limit post 18 are fixedly connected to fixing blocks 19, and the bottom end of the fixing blocks 19 is fixedly connected to the outer side of the clamping plate 10. A memory spring 20 is fixedly connected to one side of each fixing block 19, and the other end of the memory spring 20 is fixedly connected to the outer side of the limit member 17.

[0038] In this embodiment, the support rods 13 are used to support the battery side plate. The battery side plate is placed on the two support rods 13, and then the motor B802 drives the double-segment screw 803 to rotate. As the double-segment screw 803 rotates, it engages with the threads of two support members 801, causing the two clamping seats 8 to move relative to each other, bringing the two clamping plates 10 closer to the ends of the battery side plate. This achieves initial clamping of the battery side plate by the two clamping seats 8. While the two clamping seats 8 move relative to each other, the limiting sliding between the other two support members 801 and the limiting rod ensures the stability of the clamping seats 8 during movement. When the two clamping plates 10 contact the battery side plate, they stop moving due to the contact. As the clamping seats 8 continue to move and apply pressure, the hinge seat 14 will engage with the two... The adjusting plate 15 applies force, causing the two adjusting plates 15 to drive the two movable plates 12 to slide inside the movable groove 11 through the two hinges 16. When the two hinges 16 slide relative to each other, they will press on the two memory springs 20 respectively, causing the memory springs 20 to deform. At this time, the reaction force generated by the memory springs 20 under pressure and deformation will further clamp the battery side plate through the clamping plate 10. The memory springs 20 act as a buffer in this process, so as to avoid the clamping plate 10 from being unable to clamp the battery side plate firmly or from being damaged by excessive clamping force. Furthermore, the movable plate 12 drives the two support rods 13 to move in opposite directions, which will also cause the two support rods 13 to disengage from the battery side plate. Thus, when the mounting frame 3 is flipped over to inspect the other side of the battery side plate, the other side of the battery side plate can be fully exposed and will not be affected by the obstruction of other components.

[0039] In summary, the working principle of this utility model is as follows:

[0040] During use, the battery side plate to be tested is first placed on the two support rods 13. Then, the motor B802 is started to drive the double-segment screw 803 to rotate. As the double-segment screw 803 rotates, it engages with the threads between the two support members 801, causing the two clamping seats 8 to move relative to each other, bringing the two clamping plates 10 closer to the ends of the battery side plate. This achieves initial clamping of the battery side plate by the two clamping seats 8 and the clamping plates 10. When the two clamping plates 10 come into contact with the battery side plate, they stop moving due to the resistance. As the clamping seats 8 continue to move and apply pressure, the hinge seat 14 will press against the two adjusting plates 15. Applying force causes the two adjusting plates 15 to slide within the movable plates 12 via the two hinges 16. During this relative sliding, the two hinges 16 apply pressure to the two memory springs 20, causing them to deform. The resulting reaction force from this deformation further clamps the battery side plate via the clamping plate 10. The memory springs 20 act as a buffer in this process, preventing the clamping plate 10 from failing to clamp the battery side plate securely or from applying excessive clamping force that could damage the side plate. After the side plate to be tested is clamped and fixed, the motor A701 is started, causing the lead screw 702 to rotate. As the lead screw 702 rotates, it interacts with the support frame... The threaded engagement between the two screws allows the support frame 2 to move synchronously along the outer edge of the screw 702, enabling the detection head 201 to inspect the surface of the battery side plate. After one side of the battery side plate is inspected, as the support frame 2 continues to move, when the protrusion on the inner side of the bottom of the support frame enters the spiral part from the straight section of the limiting groove 401, the connecting rod 4 will be pressed by the protrusion through the spiral part of the limiting groove 401. This causes the connecting rod 4 to drive the drive gear 5 to rotate. When the drive gear 5 rotates, it will drive the two screws to rotate through the two driven gears 501. At this time, the rotation direction of the worm gear 502 is opposite to the rotation direction of the one-way bearing 3011, thus allowing the worm gear 502 to rotate in conjunction with the rotating screw. The meshing of gear 302 causes the rotating gear 302 to drive the mounting frame 3 to flip via the connecting column 301. Simultaneously, the mounting frame 3 flips, causing the battery side plate held and fixed by the clamping plate 10 to flip synchronously, thus exposing the other side of the battery side plate. This eliminates the need for manual or additional complex operations to flip the battery side plate, enabling continuous inspection and significantly shortening the inspection cycle. In large-scale production, this can significantly improve production efficiency. When the protrusion of the support frame 2 moves from the spiral position of the limiting groove 401 to the straight position, the connecting rod 4 rotates in the other direction, causing the worm gear 502 to drive the rotating gear 302 to move synchronously in the other direction. At this time, the rotation direction of the worm gear 502 is consistent with the rotation direction of the one-way bearing 3011.This ensures that the worm gear 502 can only drive the rotating gear 302 to rotate along the outer side of the connecting post 301, thus preventing the mounting frame 3 from being affected.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
