Description

Technical Field

[0001] This utility model belongs to the field of hydrogen fuel cell processing technology, and more specifically, it relates to an auxiliary installation fixture for hydrogen fuel cells. Background Technology

[0002] As a core component of new energy vehicles, the installation accuracy and stability of hydrogen fuel cells directly affect battery performance and lifespan. Auxiliary installation fixtures play a crucial role in the production and assembly of hydrogen fuel cells. However, existing hydrogen fuel cell installation fixtures still have the following problems: traditional fixtures mostly use fixed clamps, which can only accommodate hydrogen fuel cells of a single size. Since hydrogen fuel cells come in various sizes, this necessitates frequent changes of fixtures to fit the corresponding sizes during installation, increasing production costs and reducing efficiency. For example, in patent application number 202222201525.4, the device has fixed ears that connect to the connection holes on the hydrogen fuel cell, allowing the fuel cell to be installed and preventing movement during installation or maintenance. However, this device is fixed in size and can only accommodate a single size of hydrogen fuel cell. For different sizes of hydrogen fuel cells, special clamps must be selected for different battery specifications, resulting in high replacement costs and time consumption. Utility Model Content

[0027] like Figure 1An auxiliary installation fixture for a hydrogen fuel cell is shown, comprising: a workbench 1, on which a fixing mechanism for fixing the hydrogen fuel cell is provided, the fixing mechanism comprising: a fixing plate disposed on one side of the workbench 1, and a movable plate 3 slidably disposed on the other side of the workbench 1, the upper end surfaces of the movable plate 3 and the fixing plate are each provided with a fixing ear 4 connected to the corresponding side of the hydrogen fuel cell, the fixing ear 4 having a downwardly extending connecting end 41;

[0028] The workbench 1 has a lead screw 5 on its lower side wall for adjusting the position of the movable plate 3. The lower extension of the movable plate 3 is threadedly connected to the lead screw 5. The workbench 1 has a sliding groove 6 for the movable plate 3 to slide.

[0029] The surface of the fixed ear 4 is provided with multiple connecting holes 7. The connecting end 41 of the fixed ear 4 is slidably disposed in the T-shaped groove 86 opened on the upper surface of the moving plate 3 and the fixed plate. Each T-shaped groove 86 has a limiting member 9 passing through its side wall, which abuts against the connecting end 41 of the fixed ear 4.

[0030] Working principle:

[0031] Lead screws 5 are installed on the side walls on both sides below the workbench 1. The lower extension of the movable plate 3 is connected to the lead screws 5 via threads. When the lead screws 5 are rotated, the threaded drive causes the movable plate 3 to slide linearly along the surface of the workbench 1 (closer to or further away from the fixed plate). By adjusting the lead screws 5, the distance between the movable plate 3 and the fixed plate can be changed to accommodate hydrogen fuel cells of different sizes. By adjusting the lead screws 5 to move the movable plate 3, the distance between the movable plate 3 and the fixed plate is made slightly larger than the width of the hydrogen fuel cell. The battery is placed on the workbench 1, with both sides aligned with the fixed ears 4. The fixed ears 4 are slid into the T-shaped grooves 6 to align the connecting holes 7 of the fixed ears 4 with the mounting holes of the hydrogen fuel cell. Then, the position of the fixed ears 4 is locked by the limiting piece 9. The fasteners (such as bolts) between the fixed ears 4 and the battery are initially tightened to ensure the battery is stably positioned on the fixture. After confirming that the position of the hydrogen fuel cell is correct, the fasteners connecting the fixed ears 4 and the battery are fully tightened to achieve rigid fixation of the battery on the fixture. By rotating the lead screw 5, the movable plate 3 moves towards the fixed plate through the fixed plate and the fixed plate 3 set on the surface of the worktable 1. At the same time, the fixed ear 4 is slidably set in the T-shaped slide groove 86 through the connecting end 41 and the limiting member 9. This design allows the tooling to flexibly adjust the fixed spacing to adapt to hydrogen fuel cells of different sizes and specifications, avoiding the limitation of traditional fixed clamps that can only adapt to a single size.

[0032] The above technical solution also includes: a movable part 10 disposed below the workbench 1, wherein the bottom of the movable part 10 is provided with a plurality of casters 11;

[0033] The workbench 1 and the moving part 10 are connected by multiple telescopic components 12. Using this technical solution, the operator unlocks the locking mechanism of the fuma wheel 11 via a foot switch and pushes the tooling to the target workstation. The 360° steering design of the fuma wheel 11 allows the tooling to move along any trajectory, facilitating tooling movement and locking during hydrogen fuel cell installation. Simultaneously, the multiple telescopic components 12 allow the workbench 1 to be raised in space, thereby raising the hydrogen fuel cell in space. This facilitates lowering the height of the hydrogen fuel cell during movement, avoiding interference with other components. After moving to the installation position, the telescopic components 12 activate, raising the height of the hydrogen fuel cell and enhancing its adaptability during subsequent assembly.

[0034] The telescopic component 12 can be configured as a hydraulic cylinder, and the surface of the moving part 10 is provided with a control switch 15 for controlling the lifting and lowering of the telescopic component 12. During use, the worker can lift and lower the telescopic component 12 by stepping on the control switch 15.

[0035] In the above technical solution, an adjusting handle 13 is provided at one end of the lead screw 5. Using this technical solution, the position of the fixed plate on the lead screw 5 can be quickly adjusted by rotating the handle. Furthermore, the adjusting handle 13 can be replaced with a motor, and upgrading the lead screw 5 adjusting handle 13 to a motor-driven solution can achieve automated and high-precision adjustment capabilities.

[0036] In the above solution, a flexible buffer layer 14 is provided on the upper surface of the fixing ear 4. Using this technical solution, the flexible buffer layer 14 is made of elastic materials such as rubber, silicone, or sponge. It absorbs the impact force during installation through its own deformation, forming a "soft isolation" to prevent direct rigid contact between the battery and the fixing ear 4. This improves the reliability and applicability of the tooling.

[0037] The above technical solution also includes: a pair of guide rods 17 arranged between the side walls below the worktable, the guide rods 17 passing through the moving plate and the fixed plate; wherein, the guide rods 17 are located on both sides of the lead screw. This technical solution, through the symmetrical arrangement of the guide rods 17 on both sides, counteracts the radial force that may be generated during lead screw transmission (such as the lateral force caused by the clearance of the lead screw and nut pair), ensuring that the moving plate moves accurately in a single horizontal direction. Simultaneously, bearings are provided at the contact points between the guide rods 17 and the fixed plate, the moving plate, and the side walls of the worktable.

[0038] In the above technical solution, a pusher 16 is provided on one side of the moving part. Using this technical solution, the worker can easily push the moving part using the pusher 16, making it suitable for manually operated assembly lines or multi-station movements.

[0039] The limiting member is configured as a spring pin, which facilitates fixing the fixed ear after it has been moved by the spring pin.

[0040] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, this utility model is not limited to the specific details and the illustrations shown and described herein.
