Abstract
Description
Technical Field
[0001] This utility model relates to the field of testing tooling technology, and in particular to a tooling for testing CCS performance. Background Technology
[0002] The CCS integrated busbar assembly is made of highly conductive materials, which can efficiently conduct current from the battery cells to the power supply system. This efficient current conduction can reduce energy loss and improve the overall system energy efficiency. In order to improve energy storage performance and reduce the generation of scrap, it is extremely important to ensure that the CCS is in good working order before welding.
[0003] A testing fixture for CCS performance is a device specifically designed to evaluate the performance of a CCS system. It is mainly used to accurately test various performance indicators of the CCS system, such as cooling efficiency, temperature regulation capability, and the flow rate and pressure of the cooling medium. Through the fixture, different working environments and load conditions can be simulated, and the CCS system can be placed in various preset scenarios for performance evaluation.
[0004] Current testing fixtures require the CCS to be moved within the testing chamber. Frequent movement can damage the CCS. Existing technology involves installing a moving block under the testing fixture to allow the entire CCS to move. However, in actual use, this fixture cannot accommodate CCS of different specifications, and different specifications of CCS require different fixtures, resulting in poor testing efficiency. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a tooling for testing CCS performance, aiming to improve the problem that different specifications of CCS require different tooling in the prior art, resulting in poor testing efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tooling for testing CCS performance, comprising a base plate, with horizontal plates fixedly connected to the top left and right sides of the base plate, two movable plates slidably connected to adjacent sides of the two horizontal plates, sliding grooves opened on the top of the two movable plates, multiple support columns slidably connected inside the two sliding grooves, pins fixedly connected to the top of the multiple support columns, test wire harness cold-pressed terminals slidably connected to the outer walls of the multiple pins, and fastening nuts threadedly connected to the outer walls of the multiple pins, multiple wire pressing grooves equidistantly opened on the right side of the right horizontal plate, multiple fixing bolts rotatably connected to the top of the right horizontal plate, a CCS bar plate provided on the top of the base plate, and multiple positioning holes equidistantly opened on the bottom front and rear sides of the CCS bar plate.
[0007] As a further description of the above technical solution:
[0008] Limiting grooves are provided on the front and rear sides of the interior of the two movable plates, and limiting blocks are fixedly connected to the front and rear sides of the multiple supporting columns. The multiple limiting blocks are slidably connected to the interior of the corresponding limiting grooves.
[0009] As a further description of the above technical solution:
[0010] Each of the two horizontal plates has a movable groove on one of its adjacent sides, and each of the two movable plates has a movable block fixedly connected to its left and right sides.
[0011] As a further description of the above technical solution:
[0012] Each of the positioning holes has a corresponding ejector pin slidably connected to its bottom, and the ejector pin is sized to match the positioning hole.
[0013] This utility model has the following beneficial effects:
[0014] In this invention, the position of the movable plate is adjusted by sliding on the horizontal plate, which drives the support column to move in the sliding groove. The ejector pin changes position accordingly to adapt to the cold-pressed terminal of the test wire harness. The terminal is then fixed by the fastening nut, and the wire harness is tightened by the wire pressing groove and the fixing bolt. The CCS bar is positioned by the positioning hole, which enables the tooling to use CCS of different specifications and ensures the stability of the testing process. Attached Figure Description

[0022] 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.
[0023] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of a fixture for testing CCS performance, comprising a base plate 1. Horizontal plates 2 are fixedly connected to the top left and right sides of the base plate 1. The horizontal plates 2 provide lateral support and positioning for components such as movable plates 3. Two movable plates 3 are slidably connected to adjacent sides of the two horizontal plates 2. The movable plates 3 can be adjusted in position according to testing requirements, allowing the fixture to adapt to different testing conditions. Sliding grooves 4 are provided on the top of each of the two movable plates 3, providing a track for the sliding of support columns 5, allowing the support columns 5 to move within a certain range. Multiple support columns 5 are slidably connected inside the two sliding grooves 4. The support columns 5 can change position, thereby adjusting the position of the ejector pins 6 to adapt to different testing layouts. Ejector pins 6 are fixedly connected to the top of each of the multiple support columns 5. The ejector pins 6 are used to connect components such as the test harness cold-pressed terminal 7 and the CCS plate 11 to achieve signal or energy transmission. The test harness is slidably connected to the outer wall of the multiple ejector pins 6. The cold-pressed terminal 7 is used to connect the test wire harness, facilitating the testing of CCS performance. Multiple ejector pins 6 have threaded connections to their outer walls with fastening nuts 8. These nuts securely fix the cold-pressed terminal 7 to the ejector pins 6 via threaded connections, preventing loosening. Multiple wire-pressing grooves 9 are equidistantly provided on the right side of the right horizontal plate 2, providing space for the test wire harness to be accommodated and fixed. Multiple fixing bolts 10 are equidistantly rotatably connected to the top of the right horizontal plate 2. These bolts can be rotated to tighten the test wire harness, ensuring its stability during testing. A CCS bar plate 11 is located on the top of the base plate 1. The CCS bar plate 11 is the object being tested, and its performance needs to be tested using this fixture. Multiple positioning holes 12 are equidistantly provided on the front and rear sides of the bottom of the CCS bar plate 11. These holes 12 are used to cooperate with the ejector pins 6 or other positioning components to ensure the accuracy of the CCS bar plate 11's position during testing.
[0024] Specifically, the movable plate 3, which is slidably connected to the adjacent side of the horizontal plate 2, can be adjusted in position according to actual testing needs. The sliding groove 4 on the top of the movable plate 3 provides a sliding track for the support column 5. Multiple support columns 5 can move flexibly within the sliding groove 4, thereby adjusting the position of the ejector pin 6 to accommodate test wire harness cold-pressed terminals 7 of different specifications. During testing, the test wire harness cold-pressed terminal 7 is fitted onto the outer wall of the ejector pin 6, and then the test wire harness cold-pressed terminal 7 is tightly fixed to the ejector pin 6 by rotating the fastening nut 8 and using a threaded connection to ensure the stability of the connection. Multiple wire pressing grooves are equidistantly opened on the right side of the right horizontal plate 2. 9 is used to fix the test wire harness. After the wire harness is laid in the appropriate position, the fixing bolts 10, which are equidistantly connected to the top of the right horizontal plate 2, are rotated to further tighten the wire harness and prevent it from loosening during the test. The CCS bar plate 11 placed on the top of the base plate 1 has multiple positioning holes 12 equidistantly opened on the front and back sides of its bottom. These holes cooperate with other positioning structures of the tooling to ensure that the CCS bar plate 11 is accurately positioned during the test. Throughout the test, the connection between the ejector pin 6 and the cold-pressed terminal 7 of the test wire harness, as well as the positioning cooperation between the CCS bar plate 11 and the tooling, enables stable testing of the CCS performance.
[0025] Reference Figure 2 , Figure 4 and Figure 5Limiting grooves 13 are provided on the front and rear sides of the interior of the two movable plates 3. The limiting grooves 13 provide sliding space for the limiting blocks 14, ensuring the movement trajectory of the limiting blocks 14. The limiting grooves 13 provided on the front and rear sides of the interior of the two movable plates 3 can constrain and guide the components inside the movable plates 3. The front and rear sides of the multiple support columns 5 are fixedly connected to the limiting blocks 14. The limiting blocks 14 can slide in the limiting grooves 13, making the movement of the support columns 5 more stable and precise. The limiting blocks 14 on the front and rear sides of the multiple support columns 5 can prevent the support columns 5 from shifting or shaking during movement. The multiple limiting blocks 14 are all slidably connected to the interior of the corresponding limiting grooves 13, which can ensure that the support columns 5 move in a predetermined direction within the movable plates 3, thereby ensuring the positional accuracy of the ejector pin 6. Movable grooves are provided on the adjacent sides of the two horizontal plates 2. The groove 15 provides a sliding track for the moving block 16, making the movement of the moving plate 3 on the horizontal plate 2 smoother and more orderly. The left and right sides of the two moving plates 3 are fixedly connected to the moving block 16, which can slide in the moving groove 15, making the position adjustment of the moving plate 3 more convenient and standardized. The bottom of the multiple positioning holes 12 is slidably connected to the corresponding ejector pin 6, which can slide in the positioning hole 12, facilitating the precise connection between the ejector pin 6 and the CCS plate 11. The sliding connection between the multiple positioning holes 12 and the ejector pin 6 helps to ensure the relative position of the ejector pin 6 and the CCS plate 11. The size matching between the ejector pin 6 and the positioning hole 12 improves the reliability of the connection between the ejector pin 6 and the CCS plate 11. The size matching between the ejector pin 6 and the positioning hole 12 helps to ensure the accuracy and consistency of the test.
[0026] Specifically, when the support column 5 slides in the sliding groove 4, the limiting block 14 slides in the limiting groove 13. This ensures that the sliding direction and position of the support column 5 are more accurate, preventing it from shifting or rotating during the sliding process. The moving block 16 slides in the moving groove 15, making the sliding of the moving plate 3 on the horizontal plate 2 more stable. At the same time, it also limits the movement range of the moving plate 3 to prevent it from exceeding the predetermined range. The ejector pin 6 can achieve a tight fit with the CCS plate 11 through the positioning hole 12, ensuring the positional accuracy between the ejector pin 6 and the CCS plate 11, ensuring the accurate transmission of signals or energy, and enhancing the stability of the electrical connection during the test.
[0027] Working principle: When using the fixture for testing CCS performance, the movable plate 3, which is slidably connected to the adjacent side of the horizontal plate 2, can be adjusted in position according to actual testing requirements. The sliding groove 4 on the top of the movable plate 3 provides a sliding track for the support columns 5. Multiple support columns 5 can move flexibly within the sliding groove 4, thereby adjusting the position of the ejector pin 6 to accommodate test wire harness cold-pressed terminals 7 of different specifications. During testing, the test wire harness cold-pressed terminal 7 is fitted onto the outer wall of the ejector pin 6, and then the test wire harness cold-pressed terminal 7 is tightly fixed to the ejector pin 6 by rotating the fastening nut 8 and using a threaded connection to ensure the stability of the connection. The right side of the horizontal plate 2 is equidistant from the right side. The multiple wire slots 9 are used to fix the test wire harness. After the wire harness is laid in the appropriate position, the wire harness is further tightened by rotating the fixing bolts 10 that are equidistantly connected to the top of the right horizontal plate 2 to prevent it from loosening during the test. The CCS bar plate 11 placed on the top of the base plate 1 has multiple positioning holes 12 equidistantly opened on the front and back sides of its bottom. These holes cooperate with other positioning structures of the tooling to ensure that the CCS bar plate 11 is accurately positioned during the test. Throughout the test, the connection between the ejector pin 6 and the cold-pressed terminal 7 of the test wire harness, as well as the positioning cooperation between the CCS bar plate 11 and the tooling, enables stable testing of the CCS performance.
