Description

Technical Field

[0001] This utility model belongs to the technical field of new energy vehicle battery production and testing equipment, and in particular relates to a rapid positioning and clamping testing fixture for new energy vehicle battery modules. Background Technology

[0002] With the global energy structure transformation and the in-depth advancement of the "dual carbon" strategy, the new energy vehicle industry has ushered in explosive growth. As the core power source, the performance and safety of battery modules directly determine the vehicle's range, service life, and driving safety. Therefore, the full-process quality inspection of battery modules before leaving the factory has become an indispensable key process in the new energy vehicle production chain.

[0003] A positioning fixture for testing power battery modules, as described in application number CN202421806577.7, includes a worktable. A motor is fixedly installed at the bottom of the worktable, and the output end of the motor extends into the inner cavity of the worktable and is fixedly connected to a first bevel gear. A transmission rod is provided in the inner cavity of the worktable, and a second bevel gear that meshes with the first bevel gear is fixedly sleeved on the middle of the outer side of the transmission rod. First rotating wheels are fixedly sleeved on both the left and right sides of the transmission rod through the worktable. Pads are fixedly installed on both the left and right sides of the top of the worktable. This utility model can quickly clamp and limit the power battery module, preventing the power battery module from shifting during testing, improving the stability of the power battery module during testing, and also providing buffer protection for the power battery module. It effectively eliminates the vibration and impact forces experienced by the positioning fixture during use, improving the practicality of the device.

[0004] In the aforementioned patent, the battery module is clamped between the movable clamping plates by driving the movable clamping plates with a lead screw. However, when the staff places the battery module, the initial position of the module is often offset due to operational deviations. If the offset is not corrected before clamping, the actual position of the module will deviate from the detection benchmark, which will lead to the offset of the detection range and affect the accuracy of the detection results.

[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0006] To address the aforementioned problems, the purpose of this utility model is to provide a rapid positioning and clamping inspection fixture for new energy vehicle battery modules, comprising a worktable, a placement plate fixedly connected to the top surface of the worktable, a sliding groove formed on the placement plate, a fixed clamping plate fixedly connected to the top surface of the placement plate, a movable clamping plate slidably connected inside the sliding groove, and a driving assembly installed inside the sliding groove. The driving assembly includes a first threaded rod rotatably connected to the inner wall of the sliding groove, a first sliding block threadedly connected to the first threaded rod, the first sliding block being fixedly connected to the movable clamping plate, and docking components installed on both the fixed clamping plate and the movable clamping plate.

[0007] In one example, a motor is fixedly connected to the top surface of the workbench, and a rotating shaft is fixedly connected to the output end of the motor. The rotating shaft is fixedly connected to a first threaded rod.

[0008] In one example, the placement tray has an internal mounting groove, and a first rotating rod is rotatably connected to the inner wall of the mounting groove. The first rotating rod is fixedly connected to a first threaded rod, and a first helical gear is fixedly connected to the first rotating rod.

[0009] In one example, a second rotating rod is rotatably connected to the inner wall of the mounting groove, a second helical gear is fixedly connected to the second rotating rod, the second helical gear meshes with a first helical gear, a second threaded rod is fixedly connected to the end of the second rotating rod, the second threaded rod is rotatably connected to the slide groove, a second sliding block is threadedly connected to the second threaded rod, and the second sliding block is fixedly connected to the movable clamping plate.

[0010] In one example, the docking assembly includes a movable groove formed on the top of the movable clamping plate, and a plurality of limiting holes are equally spaced on the side wall of the movable clamping plate. The limiting holes communicate with the movable groove, and limiting pins are inserted into the limiting holes.

[0011] In one example, a slide block is slidably connected inside the movable slot. The slide block has a hole on its side wall, which is inserted into a limiting pin. An electric telescopic rod is fixedly connected to the top surface of the slide block. An arc-shaped seat is fixedly connected to the output end of the electric telescopic rod. Multiple springs are fixedly connected to the inner wall of the arc-shaped seat. An arc-shaped plate is fixedly connected to the end of each spring away from the arc-shaped seat.

[0012] The rapid positioning and clamping inspection fixture for new energy vehicle battery modules proposed in this utility model can bring the following beneficial effects: 1. This testing fixture utilizes the linkage structure of the motor, rotating shaft, double threaded rod, and helical gear meshing in the drive assembly to drive the movable clamping plate to move smoothly towards the fixed clamping plate. During the movement, it can automatically correct the initial position deviation of the battery module on the placement tray. After the position is calibrated, it completes stable clamping, fundamentally avoiding the problem of detection range deviation caused by module positioning offset, and greatly improving the accuracy and reliability of battery module testing results.

[0013] 2. The docking components of this testing fixture slide along the moving groove via a sliding block, and are fixed by a limit pin and multiple limit holes. With the help of an electric telescopic rod, the height of the arc-shaped seat can be flexibly adjusted, which can accurately adapt to the wire interface positions of battery modules of different sizes and specifications. There is no need to equip different models of modules with separate fixtures, which significantly reduces the equipment investment cost of enterprises and greatly improves the versatility and applicability of the fixture.

[0014] 3. In the docking assembly of this testing fixture, the inner wall of the arc-shaped seat is connected to the arc-shaped plate by a spring. The arc-shaped plate is made of rubber and has anti-slip texture on the inner wall. When fixing the testing line, the elasticity of the spring can adapt to lines of different diameters. At the same time, the rubber arc-shaped plate can prevent the line from making hard contact with the metal parts, which not only achieves a stable docking of the testing line, but also provides a buffer protection for the line and reduces the risk of line damage.

[0015] 4. This testing fixture can make the moving clamp plate more evenly stressed, and there is no jamming or tilting during the movement. When clamping, it can provide a stable and balanced clamping force for the battery module, effectively preventing the module from shaking during the testing process and ensuring the stability of the testing operation.

[0027] like Figures 1-5 As shown in the figure, an embodiment of this utility model proposes a rapid positioning and clamping inspection fixture for a new energy vehicle battery module, which includes a workbench 1. A placement plate 2 is fixedly connected to the top surface of the workbench 1. A slide groove 21 is provided on the placement plate 2. A fixed clamping plate 3 is fixedly connected to the top surface of the placement plate 2. A movable clamping plate 4 is slidably connected inside the slide groove 21. A drive assembly 5 is installed inside the slide groove 21. The drive assembly 5 includes a first threaded rod 53 rotatably connected to the inner wall of the slide groove 21. A first sliding block 531 is threadedly connected to the first threaded rod 53. The first sliding block 531 is fixedly connected to the movable clamping plate 4. A docking assembly 6 is installed on both the fixed clamping plate 3 and the movable clamping plate 4.

[0028] Specifically, a motor 51 is fixedly connected to the top surface of the workbench 1, and a rotating shaft 52 is fixedly connected to the output end of the motor 51. The rotating shaft 52 is fixedly connected to the first threaded rod 53.

[0029] Specifically, the interior of the placement plate 2 is provided with an installation groove 22, and the inner wall of the installation groove 22 is rotatably connected to a first rotating rod 54. The first rotating rod 54 is fixedly connected to a first threaded rod 53, and a first helical gear 55 is fixedly connected to the first rotating rod 54.

[0030] Specifically, a second rotating rod 56 is rotatably connected to the inner wall of the mounting groove 22, and a second helical gear 57 is fixedly connected to the second rotating rod 56. The second helical gear 57 meshes with the first helical gear 55. Both the first helical gear 55 and the second helical gear 57 are helical gears with a helix angle of 45° and have the same number of teeth, which enables the first threaded rod 53 and the second threaded rod 58 to rotate synchronously in opposite directions. Moreover, the threads on the first threaded rod 53 and the second threaded rod 58 are opposite, thereby realizing the synchronous movement of the two sliding blocks towards or away from each other.

[0031] The end of the second rotating rod 56 is fixedly connected to a second threaded rod 58, which is rotatably connected to the slide groove 21. A second sliding block 59 is threadedly connected to the second threaded rod 58, and the second sliding block 59 is fixedly connected to the movable clamping plate 4.

[0032] Specifically, the docking component 6 includes a movable groove 61 opened on the top of the movable clamping plate 4. The side wall of the movable clamping plate 4 is provided with a plurality of limiting holes 62 at equal intervals. The limiting holes 62 communicate with the movable groove 61. Limiting pins 63 are inserted into the limiting holes 62. The number and spacing of the limiting holes 62 need to be set according to the actual situation.

[0033] Specifically, a slide block 64 is slidably connected inside the movable slot 61. The side wall of the slide block 64 has an insertion hole 641, which is inserted into the limiting pin 63. An electric telescopic rod 65 is fixedly connected to the top surface of the slide block 64. An arc-shaped seat 66 is fixedly connected to the output end of the electric telescopic rod 65. Multiple springs 67 are fixedly connected to the inner wall of the arc-shaped seat 66. An arc-shaped plate 68 is fixedly connected to the end of the multiple springs 67 away from the arc-shaped seat 66.

[0034] Working Principle: When using this new energy vehicle battery module rapid positioning and clamping testing fixture, the battery module to be tested is first placed on the placement tray 2, so that one side of the battery module is in contact with the fixed clamping plate 3. Then, the motor 51 is started, and the motor 51 drives the rotating shaft 52 to rotate. The rotating shaft 52 drives the first threaded rod 53 to rotate. The first threaded rod 53 drives the movable clamping plate 4 to move along the slide groove 21 towards the fixed clamping plate 3 through the first sliding block 531. At the same time, the first threaded rod 53 drives the first rotating rod 54 to rotate. The first helical gear 55 on the first rotating rod 54 meshes with the second helical gear 57, which in turn drives the second rotating rod 56 to rotate. The second rotating rod 56 drives the second threaded rod 58 to rotate. The second threaded rod 58 further drives the movable clamping plate 4 to move through the second sliding block 59 until the two movable clamping plates 4 are in contact with the other side of the battery module, realizing the clamping and positioning of the battery module.

[0035] Next, adjust the docking assembly 6 according to the position of the connector on the battery module. By sliding the slide block 64 in the moving groove 61, when the slide block 64 moves to the appropriate position, insert the limit pin 63 into the corresponding limit hole 62 and insertion hole 641 to fix the slide block 64. Then, start the electric telescopic rod 65. The electric telescopic rod 65 drives the arc-shaped seat 66 to move upward to the battery module connector. The operator places the test wire on the arc-shaped seat 66. During the placement process, it will contact the arc plate 68, which will cause the spring 67 to be compressed. After the placement is completed, the spring 67 will return to its original position, thus placing the test line on the arc-shaped seat 66, thereby ensuring the docking of the test line with the connector on the battery module. At the same time, the anti-slip pad on the inner wall of the arc plate 68 can increase the friction between the test line and the test wire to prevent the test wire from sliding.

[0036] After the battery module is positioned and connected, various tests can be performed. After testing, the test wires are disconnected from the battery module interface, and the electric telescopic rod 65 is retracted, thereby resetting the arc-shaped seat 66 and the test wires. The limit pin 63 is pulled out, and the slide 64 is moved to its initial position. Then, the motor 51 is reversed, driving the rotating shaft 52, the first threaded rod 53, the first rotating rod 54, the second rotating rod 56, and the second threaded rod 58 to rotate in opposite directions, causing the movable clamping plate 4 to move away from the fixed clamping plate 3, releasing the battery module. Finally, the tested battery module can be removed from the placement tray 2.

[0037] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0038] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
