[0024] To more clearly illustrate the design schemes in the embodiments of this utility model, the utility model will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting. Obviously, the drawings in the following description are only some embodiments of this utility model. For those skilled in the art, all other embodiments obtained without creative effort are within the protection scope of this utility model.
[0025] The present invention will now be described in further detail with reference to the accompanying drawings.
[0026] like Figure 1-5 As shown, this utility model includes a support platform 1, which has screw holes for fixing to a vibration testing device with bolts. The size of the support platform is suitable for testing all sizes of European lead-acid batteries. Two transverse rails 2 are fixed to the support platform with bolts, and the rail spacing is designed to be slightly larger than the battery width by 30mm. Two longitudinal rails 3 are mounted on the transverse rails and can move on the transverse rails. Movable clamping blocks 4 are installed on the rails and can move freely on the rails. They can be fixed in place by tightening bolts 5 when they slide to a suitable position. A pressure block assembly 6 is installed on the inner side of the movable clamping block 4. It adopts a groove design and has a rubber pad fixed on its surface, which can match the lower fixing structure of the European lead-acid battery to fix the battery.
[0027] The support platform 1 is made of high-strength, high-rigidity 45# steel to ensure the stability of the fixture during vibration testing. The dimensions of support platform 1 are slightly larger than the largest European-style lead-acid battery. Its dimensions are designed based on the size range of common European-style lead-acid batteries and the platform size of the vibration testing equipment, measuring 800mm in length, 600mm in width, and 20mm in thickness, slightly larger than the largest European-style lead-acid battery. The surface of support platform 1 is precision-machined to form a flat plane, and threaded holes and lateral adjustment rail mounting holes are provided at appropriate locations for mounting and fixing components, facilitating subsequent installation and adjustment of various parts.
[0028] For European-style batteries designed for bottom mounting, the width is fixed. Based on the width of the European-style battery, two parallel transverse adjustment rails 2 are installed on the support platform 1. The transverse adjustment rails adopt T-slot guide rails, which are characterized by high precision and high rigidity. The length of the rails is designed according to the length of the support platform, which can cover all possible battery length ranges, allowing the tooling to adapt to different models of European-style lead-acid batteries.
[0029] Two longitudinal adjusting rails 3, also using T-slot guide rails, are installed on the transverse adjusting rail 2. The sliding direction of the longitudinal adjusting rail 3 on the transverse adjusting rail is the same as the extension direction of the transverse adjusting rail. The longitudinal adjusting rail 3 can slide freely on the transverse adjusting rail and be fixed in the required position by a locking device, thereby adapting to batteries of different lengths and further improving the versatility of the tooling. Both longitudinal rails are movable, ensuring that batteries of different sizes are located in the center of the support platform.
[0030] A movable clamping block 4 is also provided between the two longitudinal adjustment rails on the transverse adjustment rail 2. The movable clamping block 4 can slide freely on the transverse adjustment rail 2 and be fixed in the required position by the locking device.
[0031] A clamping block assembly 6 is installed on the movable clamping block 4 and the longitudinal adjustment track 3. The clamping block assembly 6 is made of high-strength aluminum alloy and its surface is anodized to improve wear resistance and corrosion resistance. The inner side of the clamping block assembly 6 has a certain slope and is equipped with a rubber pad to ensure full contact with the lower fixing protrusion of the battery. This not only prevents damage to the battery but also increases friction, ensuring a more secure battery fixation. The clamping block assembly 6 is connected to the movable clamping block 4 / longitudinal adjustment track 3 by bolts and nuts, enabling clamping of batteries of different sizes and meeting the fixing needs of various battery specifications. There are at least four clamping block assemblies 6, symmetrically distributed on the four sides of the battery.
[0032] The pressure block assembly 6 includes a contoured pressure block 61 and a bent pressure plate 62 for connecting the contoured pressure block 61 to the longitudinal adjustment track 3 / movable clamping block 4. The bent pressure plate 62 is Z-shaped and has a certain downward pressing force. The bent pressure plate 62 consists of a lower horizontal plate 621 connected to the upper part of the contoured pressure block 61, an upper horizontal plate 622 connected to the upper part of the longitudinal adjustment track 3 / movable clamping block 4, and a vertical plate 623 connecting the lower horizontal plate 621 and the upper horizontal plate 622. The movable clamping block 4 has an upper horizontal plate mounting hole. The longitudinal adjustment track 3 has multiple upper horizontal plate mounting holes. The upper horizontal plate 622 is connected to the upper horizontal plate mounting hole via a clamping bolt and a quick-locking nut according to the position of the fixed protrusion structure at the bottom of the short side of the battery under test. By tightening the quick-locking nut, the contoured pressure block 61 is pressed tightly onto the battery to ensure that the battery does not shift during the vibration test. The number and position of the conformal clamping blocks 61 and the clamping bolts are arranged reasonably according to the size and weight of the battery to ensure the reliability of the fixation and to keep the battery stable under various vibration conditions.
[0033] To improve the efficiency of tooling, quick-locking mechanisms, such as quick-release clamps or quick-release nuts, can be used for the longitudinal adjustment mechanism and the locking device of the movable clamp. This allows operators to quickly install and remove batteries, significantly reducing test preparation time, improving work efficiency, and adapting to the needs of large-volume, diverse testing.
[0034] Taking the L2 battery as an example, place the European-style lead-acid battery 7 to be tested in the middle of the support platform 1 connected to the vibration testing equipment. Slide the movable clamping block 4 to the fixed protruding edge structure at the bottom of the long side of the battery. Use the screw and quick-locking nut to connect the upper horizontal plate 622 to the mounting hole of the upper horizontal plate. The pressing surface of the contoured pressure block 61 is in contact with the lower fixing structure of the battery. Fix the clamping bolt 5, and the longitudinal fixing of the battery is completed. Slide the longitudinal adjustment rail 3 until the pressing surface of the contoured pressure block 61 in the upper pressure block assembly 6 is in contact with the fixed protruding edge structure at the bottom of the short side of the battery. Tighten the clamping bolt to fix the position of the longitudinal adjustment rail 3, and the lateral fixing of the battery is completed. At this time, the battery is fixed to the support platform. Check all clamping bolts to ensure that they are firmly fixed. Turn on the vibration testing equipment to conduct vibration testing. After the test is completed, loosen the clamping bolts and move the longitudinal adjustment rail and movable clamping block to quickly complete the battery disassembly.
