Description

Technical Field

[0001] This application relates to the field of fixture and tooling technology, and in particular to a test fixture. Background Technology

[0002] Traditional clamps often fail to ensure that the top surface of the battery is flush with the top surface of the clamp when holding batteries. This inaccurate clamping can lead to poor contact between the welding torch and the battery during welding, affecting welding quality and potentially damaging the battery assembly. Furthermore, because batteries may have tolerances in size and shape, traditional clamps lack flexibility in adjusting battery position and are difficult to adapt to batteries of different specifications.

[0003] Existing fixtures are complex in structure and cumbersome in adjustment, requiring operators to spend considerable time and effort adjusting the battery position, thus reducing production efficiency. Furthermore, unstable clamping conditions can cause battery displacement during welding, further affecting welding accuracy. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this application provides a test fixture to meet the clamping requirements of batteries of different specifications, simplify the operation process, and improve production efficiency and welding accuracy.

[0005] To achieve the above objectives, this application adopts the following technical solution: A test fixture includes a clamping space and an adjusting member. The clamping space has an opening. The adjusting member is disposed within the clamping space and can move along a second direction within the clamping space to move the battery along the second direction, thereby adjusting the distance between the battery and the opening to accommodate batteries of different heights and sizes. The second direction is perpendicular to the first direction and points towards the opening.

[0006] In one embodiment, the clamping plate assembly includes a first clamping plate and a second clamping plate, with the clamping space formed between the first clamping plate and the second clamping plate; the adjusting member is movably connected to the first clamping plate and / or the second clamping plate to move along a second direction.

[0010] In one embodiment, the slide rail includes a connecting portion and a sliding portion. One of the first clamping plate and the second clamping plate is connected to the connecting portion. The connecting portion forms a receiving groove. The sliding portion is disposed in the receiving groove and forms a sliding groove extending along the second direction. The adjusting member is slidably connected to the sliding groove. The locking member is connected to the adjusting member and can be selectively abutted against the sliding portion to selectively fix the adjusting member and the sliding portion.

[0011] In one embodiment, the adjusting member extends along a third direction to support the battery, and the clamping plate assembly includes a pair of slide rails facing each other along the third direction, with both ends of the adjusting member slidingly engaged with the pair of slide rails respectively; the third direction is perpendicular to the first direction and the second direction respectively.

[0012] In one embodiment, the locking member is threadedly engaged with the adjusting member, and is used to selectively abut against the sliding part by rotating relative to the adjusting member.

[0013] In one embodiment, the clamp assembly includes a connector that connects the first clamping plate and the second clamping plate respectively. The connector is movable relative to the first clamping plate and the second clamping plate in a first direction to accommodate batteries of different thicknesses.

[0014] In one embodiment, the first clamping plate has a first fixing hole, and the second clamping plate has a second fixing hole. The connecting member includes a screw and a set of nuts. The screw extends along a first direction and includes a first end and a second end that are disposed opposite to each other. The first end passes through the first fixing hole and abuts against the first clamping plate. The second end passes through the second fixing hole and is locked by the set of nuts. The second clamping plate is clamped between the set of nuts. The set of nuts are threadedly engaged with the screw to adjust the position of the second clamping plate and the screw, thereby adapting to batteries of different thicknesses and sizes.

Detailed Implementation

[0017] In this application, the terms "set up," "equipped with," and "connected" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0018] The terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “radial,” and “circumferential” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0019] To make the objectives, technical solutions, and advantages of 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 not intended to limit the scope of this application.

[0020] See Figure 1 This application provides a test fixture, including a clamping space 13 and an adjusting member 2. The clamping space 13 is used to clamp a battery 5 along a first direction and has an open opening. The adjusting member 2 is disposed in the clamping space 13 and can move along a second direction within the clamping space 13 to drive the battery 5 to move along the second direction, thereby adjusting the distance between the battery 5 and the open opening to adapt to batteries 5 of different heights and sizes. The second direction is perpendicular to the first direction and points towards the open opening.

[0021] To describe clearly, Figure 1 The X direction represents the first direction, and the Z direction represents the second direction.

[0022] In practical applications, the test fixture forms a clamping space 13, which clamps the battery 5 along a first direction. The clamping space 13 has an open opening for the top of the battery 5 to be exposed. The first direction is generally perpendicular to the clamping surface of the battery 5, which facilitates the clamping and releasing of the battery 5.

[0023] Adjustment member 2 is located within clamping space 13 and can move along a second direction. This second direction is perpendicular to the first direction, typically vertical, and points towards the opening. Movement of adjustment member 2 allows battery 5 to move along this second direction. This design allows battery 5 to be adjusted within clamping space 13 according to different height dimensions, ensuring the top of battery 5 is flush with the opening of clamping space 13, facilitating welding and other operations.

[0024] It should be noted that the top of battery 5 usually refers to the side of battery 5 where the terminals are located.

[0025] Compared to existing technologies, the test fixture of this application can adapt to batteries 5 of different heights and sizes, increasing the versatility and flexibility of the test fixture. Furthermore, the precise movement of the adjusting member 2 ensures the stability of the battery 5 during testing, improving the accuracy and efficiency of the test.

[0026] See again Figure 1 The test fixture also includes a clamping plate assembly, which includes a first clamping plate 11 and a second clamping plate 12, forming a clamping space 13 between the first clamping plate 11 and the second clamping plate 12; the adjusting member 2 is movably connected to the first clamping plate 11 and / or the second clamping plate 12 to move along a second direction.

[0027] In practical applications, the clamping assembly consists of a first clamping plate 11 and a second clamping plate 12, forming a clamping space 13 between them. The clamping space 13 is used to accommodate and fix the battery 5, ensuring that the battery 5 remains stable during clamping. The movable connection design between the adjusting member 2 and the first clamping plate 11 and / or the second clamping plate 12 allows the adjusting member 2 to be precisely adjusted in position, ensuring that the upper surface of the battery 5 is flush with the opening, thus improving the reliability and efficiency of the test.

[0028] It should be noted that the movable connection means that the adjusting member 2 can move or rotate relative to the first clamping plate 11 or the second clamping plate 12.

[0029] See Figure 2 The first clamping plate 11 and / or the second clamping plate 12 can be slidably connected to the adjusting member 2. Taking the sliding connection between the adjusting member 2 and the second clamping plate 12 as an example, the configuration of the adjusting member 2 will be explained.

[0030] In practical applications, the adjusting member 2 and the second clamping plate 12 are slidably connected to enable the adjusting member 2 to move relative to the second clamping plate 12 in the second direction, thereby enabling the adjusting member 2 to drive the battery 5 to move, so that the top of the battery 5 is exposed from the opening.

[0031] It should be noted that, in addition to sliding connection, the adjusting member 2 can also adopt other movable connection methods, such as rotation or rolling, which is not limited in this application.

[0032] See Figure 3 The test fixture includes a locking element 3, which is connected to the adjusting element 2 and the clamping plate assembly to restrict the movement of the adjusting element 2.

[0033] In practical applications, the locking component 3 is designed to effectively fix the adjusting component 2 after it is adjusted to the required position, preventing it from shifting due to vibration or external force during the test. The locking component 3 can be a structure such as bolts or rivets.

[0034] See again Figure 3The clamping plate assembly includes a slide rail 14 extending in a second direction, one of a first clamping plate 11 and a second clamping plate 12 connected to the slide rail 14, an adjusting member 2 slidably connected to the slide rail 14, and a locking member 3 connected to the adjusting member 2 and the slide rail 14 respectively to fix the adjusting member 2 and the slide rail 14.

[0035] Here, we will explain the configuration of the slide rail 14 by taking the second clamping plate 12 connected to the slide rail 14 as an example.

[0036] In practical applications, the second clamping plate 12 is connected to a slide rail 14, which extends along the second direction. The adjusting member 2 and the slide rail 14 are slidably connected, so that the adjusting member 2 can move along the second direction, thereby driving the battery 5 to move along the second direction. When the adjusting member 2 slides to the preset position, the locking member 3 ensures that the adjusting member 2 and the slide rail 14 can be firmly held in the preset position after adjustment, preventing accidental displacement during testing.

[0037] It is understandable that if the slide rail 14 is connected to the first clamping plate 11, the setting method is similar to that of the second clamping plate 12, and will not be described in detail here.

[0038] See again Figure 3 The slide rail 14 includes a connecting part 141 and a sliding part 142. One of the first clamping plate 11 and the second clamping plate 12 is connected to the connecting part 141. The connecting part 141 forms a receiving groove 1411. The sliding part 142 is disposed in the receiving groove 1411 and forms a sliding groove 1421 extending in the second direction. The adjusting member 2 is slidably connected to the sliding groove 1421. The locking member 3 is connected to the adjusting member 2 and can be selectively abutted against the sliding part 142 to selectively fix the adjusting member 2 and the sliding part 142.

[0039] In practical applications, the connecting part 141 is used to connect with one of the clamping plates, providing a stable fixing base. The design of the receiving groove 1411 allows the sliding part 142 to be embedded therein, ensuring that the sliding part 142 is stably positioned within the receiving groove 1411. The sliding groove 1421 on the sliding part 142 extends along the second direction, providing track support for the sliding of the adjusting member 2, allowing the adjusting member 2 to move smoothly along a predetermined path. The adjusting member 2, through its sliding connection with the sliding groove 1421, achieves adjustment of the position of the battery 5, facilitating adaptation to test objects of different sizes. The locking member 3 not only connects to the adjusting member 2 but can also selectively abut against the sliding part 142. This design allows the user to fix the adjusting member 2 and the sliding part 142 by the locking member 3 after adjusting the position of the adjusting member 2, ensuring positional stability.

[0040] See again Figure 1 and Figure 3The adjusting member 2 extends along a third direction to support the battery 5. The clamping plate assembly includes a pair of slide rails 14 facing each other along the third direction. The two ends of the adjusting member 2 are respectively slidably engaged with the pair of slide rails 14. The third direction is perpendicular to the first direction and the second direction, respectively.

[0041] To describe clearly, Figure 1 In this diagram, the X direction represents the first direction, the Z direction represents the second direction, and the Y direction represents the third direction.

[0042] In practical applications, the adjusting member 2 extends along a third direction to support the battery 5, ensuring its stability and safety during testing. A pair of slide rails 14 are positioned opposite each other along the third direction, providing symmetrical support for the adjusting member 2 and ensuring its stable sliding and support of the battery 5. Both ends of the adjusting member 2 slide into the pair of slide rails 14, allowing for smooth movement between them, facilitating user adjustment to accommodate batteries 5 of different sizes and shapes. The third direction is perpendicular to the first and second directions, ensuring the stability of the test fixture in space while providing flexible adjustment and adaptability.

[0043] See again Figure 3 The locking member 3 is threadedly engaged with the adjusting member 2 and is used to selectively abut against the sliding part 142 by rotating relative to the adjusting member 2.

[0044] In one embodiment, the locking member 3 can be a bolt or similar structure, and the locking member 3 and the adjusting member 2 are connected by a thread. This connection allows the locking member 3 to move along the adjusting member 2 by rotation, providing an adjustable fixing function. The locking member 3 can be rotated to tighten or loosen its contact with the sliding part 142, thereby selectively fixing or releasing the adjusting member 2. This design provides a simple operating method and improves the flexibility of the test fixture.

[0045] See Figure 4 The clamp assembly 1 includes a connector 4, which is connected to the first clamping plate 11 and the second clamping plate 12 respectively. The connector 4 can move relative to the first clamping plate 11 and the second clamping plate 12 in a first direction to adapt to batteries 5 of different thicknesses.

[0046] In practical applications, the connector 4 structurally connects the first clamping plate 11 and the second clamping plate 12 to form an integral clamping assembly 1. The connector 4 can move relative to the first clamping plate 11 and the second clamping plate 12 along a first direction. This mobility allows the clamp to be flexibly adjusted to accommodate batteries 5 of different sizes and thicknesses, increasing the versatility of the device. Through the design of the connector 4, the distance between the two clamping plates can be adjusted to accommodate batteries 5 of different thicknesses.

[0047] See again Figure 4 The first clamping plate 11 has a first fixing hole 111, and the second clamping plate 12 has a second fixing hole 121. The connector 4 includes a screw 41 and a set of nuts 42. The screw 41 extends along a first direction and includes a first end 411 and a second end 412 that are disposed opposite to each other. The first end 411 passes through the first fixing hole 111 and abuts against the first clamping plate 11. The second end 412 passes through the second fixing hole 121 and is locked by the set of nuts 42. The second clamping plate 12 is clamped between the set of nuts 42. The set of nuts 42 is threadedly engaged with the screw 41 to adjust the position of the second clamping plate 12 and the screw 41, thereby adapting to batteries 5 of different thicknesses and sizes.

[0048] In practical applications, the first clamping plate 11 and the second clamping plate 12 are respectively provided with a first fixing hole 111 and a second fixing hole 121. The first fixing hole 111 and the second fixing hole 121 are holes with smooth inner surfaces, meaning that the inner walls of the holes are free of threads or other interfering structures, allowing the screw 41 to pass through smoothly. The smooth inner walls of the holes reduce friction and wear on the screw 41 during position adjustment. Simultaneously, during battery 5 testing, as the battery 5 expands due to heat, the smooth holes reduce the mechanical constraints on the screw 41, making it easier to fine-tune the screw 41 and avoid applying excessive pressure to the battery 5. When the battery 5 expands, the smooth holes allow the screw 41 slight room to move within the holes, allowing the clamping plates to adjust their position within a small range to accommodate changes in the volume of the battery 5. This helps protect the structural integrity of the clamping plates and prevents damage due to expansion.

[0049] The screw 41 is used in conjunction with a set of nuts 42. One end of the screw 41 passes through the first fixing hole 111 and abuts against the first clamping plate 11, while the other end passes through the second fixing hole 121 of the second clamping plate 12 and is locked by the nuts 42. Specifically, nuts 42 are provided on both opposite sides of the second clamping plate 12, and the second clamping plate 12 is clamped between the two nuts 42. The threaded engagement of the nuts 42 allows the position of the second clamping plate 12 relative to the screw 41 to be adjusted. By adjusting the position of the nuts 42 on the screw 41, the relative position of the second clamping plate 12 and the screw 41 can be changed, thereby adjusting the distance between the first clamping plate 11 and the second clamping plate 12 to accommodate batteries 5 of different thicknesses. This design provides high flexibility and adaptability. The locking action of the nuts 42 on the screw 41 ensures the stability of the second clamping plate 12 in the set position, preventing accidental movement of the clamping plate during use and ensuring the secure clamping of the battery 5.

[0050] It is understood that the first clamping plate 11 can also be clamped between a set of nuts 42. The specific settings can be referred to the foregoing, and will not be repeated here.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0052] Furthermore, in addition to indicating location or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0053] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
