Technical Field

[0001] This invention relates to the field of new energy vehicle production, and in particular to a hydrogen refueling port pressing device for hydrogen fuel cell vehicles. Background Technology

[0002] Currently, in the production of hydrogen fuel cell vehicles, the number of hydrogen fuel cell vehicle brands and models is increasing. Hydrogen fuel cell vehicles are equipped with hydrogen refueling ports, which require a certain level of strength, necessitating the installation of reinforcing components. Traditionally, this installation is done manually, using a folding press. This method is inefficient and lacks precision, affecting product quality. Furthermore, some special reinforcing components require two folds to achieve a secure connection with the side panel, and different press heads are used for each fold. After one fold, a different press head is needed, further exacerbating the aforementioned problems.

[0003] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0004] The present invention addresses the aforementioned shortcomings of existing technologies by proposing a hydrogen refueling port pressing device for hydrogen energy vehicles that is simple in structure, ingenious in design, and rational in layout, thereby improving production efficiency while effectively controlling costs.

[0005] The technical solution of the present invention is: a hydrogen refueling port pressing device for hydrogen energy vehicles, characterized in that: the device includes a bottom frame 1, a pressing frame 2 movably connected to the bottom frame 1, and a clamping base plate 3 is also provided on the side of the bottom frame 1.

[0006] The bottom frame 1 is provided with a pair of X-axis guide rails 4, and a slider is slidably connected to the X-axis guide rails 4. The slider is connected to the bottom of the pressing frame 2. The bottom frame 1 is also provided with a quick positioning clamp 5 that matches the pressing frame 2.

A workpiece positioning mechanism 8 and a workpiece positioning cylinder 9 are also provided on the pressing frame 2.

[0008] The fixture base plate 3 is provided with a mold 10 and a plurality of fixtures 11.

[0009] The workpiece positioning mechanism 8 includes a positioning mechanism frame 12. Spring rods 13 are provided at each of the four top corners of the positioning mechanism frame 12. A pair of positioning mechanism Z-axis guide rails 14 are provided on each of the two opposite sides of the positioning mechanism frame 12. The positioning mechanism Z-axis guide rails 14 are slidably connected to guide blocks 15 fixedly connected to the pressing frame 2. Multiple clamps 11 are provided at the bottom of the positioning mechanism frame 12. Additionally, two symmetrically distributed support rods 25 are provided on the positioning mechanism frame 12.

[0010] The workpiece positioning cylinder 9 is a swing cylinder, and a pressure block 16 is provided at the end of its swing arm. The pressure block 16 is matched with the support rod 25.

[0011] The pressing frame 2 is also provided with two pressing head replacement mechanisms 17, and the two pressing head replacement mechanisms 17 are symmetrically distributed about the axis of the pressing cylinder 6.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This hydrogen fuel cell vehicle refueling port pressing device features a simple structure, ingenious design, and reasonable layout. Addressing the problems of traditional manual pressing methods, it employs a unique semi-automatic structure. Multiple clamps on a fixture base plate position the side panel, while multiple clamps at the bottom of the workpiece positioning mechanism position the reinforcing member. The workpiece positioning mechanism drives the reinforcing member downwards to contact the refueling port on the side panel. A workpiece positioning cylinder then presses the workpiece positioning mechanism firmly. After preparation, the pressing cylinder drives the pressing head downwards for the first fold.

[0022] Specific embodiments of the present invention will now be described in conjunction with the accompanying drawings. Figures 1 to 5 As shown: A hydrogen refueling port pressing device for a hydrogen fuel cell vehicle includes a bottom frame 1, a pressing frame 2 movably connected to the bottom frame 1, and a clamping base plate 3 disposed on the side of the bottom frame 1.

[0023] The bottom frame 1 is provided with a pair of X-axis guide rails 4, and a slider is slidably connected to the X-axis guide rails 4. The slider is connected to the bottom of the pressing frame 2. The bottom frame 1 is also provided with a quick positioning clamp 5 that matches the pressing frame 2.

[0024] A pressing cylinder 6 is provided at the top of the pressing frame 2, and a quick-change pressure head 7 is connected to the bottom end of the output shaft of the pressing cylinder 6. A workpiece positioning mechanism 8 and a workpiece positioning cylinder 9 are also provided on the pressing frame 2.

[0025] The fixture base plate 3 is provided with a mold 10 and a plurality of fixtures 11.

[0026] The workpiece positioning mechanism 8 includes a positioning mechanism frame 12. Spring rods 13 are provided at each of the four top corners of the positioning mechanism frame 12. A pair of positioning mechanism Z-axis guide rails 14 are provided on each of the two opposite sides of the positioning mechanism frame 12. The positioning mechanism Z-axis guide rails 14 are slidably connected to guide blocks 15 fixedly connected to the pressing frame 2. Multiple clamps 11 are provided at the bottom of the positioning mechanism frame 12. Additionally, two symmetrically distributed support rods 25 are provided on the positioning mechanism frame 12.

[0027] The workpiece positioning cylinder 9 is a swing cylinder, and a pressure block 16 is provided at the end of its swing arm. The pressure block 16 is matched with the support rod 25.

[0028] The pressing frame 2 is also provided with two pressing head replacement mechanisms 17, and the two pressing head replacement mechanisms 17 are symmetrically distributed about the axis of the pressing cylinder 6.

[0029] The pressure head replacement mechanism 17 includes a longitudinal moving frame 18, which is slidably connected to a pressure head replacement Z-axis guide rail 19 disposed on the pressing frame 2. The longitudinal moving frame 18 is also connected to an L-shaped connector 20 via a spring rod 13, and the top end of the L-shaped connector 20 is fixedly connected to the pressing frame 2.

[0030] The inner side of the longitudinal frame 18 is also provided with a Y-axis guide rail 21, and a Y-axis platform 22 is slidably connected on the Y-axis guide rail 21. A bracket 23 is provided at the bottom of the Y-axis platform 22, and a quick-change pressure head positioning frame 24 is provided at the end of the bracket 23.

[0031] A spring pin 26 is provided at the top of the Y-axis platform 22, and a positioning frame 27 matching the spring pin 26 is provided at the end of the longitudinal frame 18.

[0032] The working process of the hydrogen refueling port pressing device of the present invention is as follows: In the initial state, the pressing frame 2 is located at one end of the bottom frame 1. At this time, there are no obstacles in the space above the clamping base plate 3. The side panel is placed on the clamping base plate 3 by a robot or other transfer device and fixed by the clamp 11.

[0033] At the same time, the reinforcing member is placed at the bottom of the positioning mechanism frame 12, and the reinforcing member is fixed by multiple clamps 11 provided there.

[0034] Then push the pressing frame 2 to slide on the bottom frame 1 until the pressing frame 2 moves to the top of the mold 10. After it moves into place, use the quick positioning clamp 5 to lock the pressing frame 2.

[0035] The operator pulls the positioning mechanism frame 12 downwards by hand, and the positioning mechanism frame 12 moves the bottom reinforcement down together until the reinforcement contacts the side outer plate below it. Then the workpiece positioning cylinder 9 is activated, and the pressure block 16 at the end of the swing arm of the workpiece positioning cylinder 9 presses on the support rod 25. At this time, the operator releases his hand and leaves the device, and then presses the button that controls the pressing cylinder 6. The pressing cylinder 6 moves the first quick-change pressure head 7 down, and the quick-change pressure head 7 performs the first flanging operation on the reinforcement.

[0036] After one pressing action is completed, the first quick-change press head 7 returns to the initial position. The operator uses the press head changing mechanism 17 to change to the second quick-change press head 7. Then the operator drives the press head changing mechanism 17 to reset and leaves the device. Pressing the button again causes the pressing cylinder 6 to drive the second quick-change press head 7 to move downward. The second quick-change press head 7 performs a second flanging operation on the reinforcing part.

[0037] After two flanging and pressing operations, the reinforcing member and the side panel are securely connected. Then, the clamp 11 at the bottom of the positioning mechanism frame 12 is opened by the control system (the clamp 11 here is a clamp that can be operated manually or automatically). After the connection is lost, the positioning mechanism frame 12 rises and returns to the initial position under the action of the spring rod 13. Then, the quick positioning clamp 5 is opened, the pressing frame 2 is pushed back to the initial position, and all the clamps 11 on the clamp base plate 3 are opened. The side panel with the reinforcing member connected is removed, and another side panel without the reinforcing member is replaced. The above process is repeated.

[0038] During the pressing and flanging process, the mold 10 supports the outer side panel from below to prevent it from deforming under the pressure of the press head.

[0039] When the quick-change pressure head 7 needs to be replaced using the pressure head replacement mechanism 17, the operator holds the Y-axis platform 22 and pulls it down. Since the Y-axis platform 22 is connected to the longitudinal frame 18 through the Y-axis guide rail 21, the Y-axis platform 22 can drive the longitudinal frame 18 to move downward. At this time, the spring rod 13 on the longitudinal frame 18 and the L-shaped connector 20 is stretched. While keeping the Y-axis platform 22 in a low position, the Y-axis platform 22 is pushed along the Y-axis direction, so that the pressure head positioning frame 24 at its end moves to below the quick-change pressure head 7. The spring pin 26 automatically locks in the positioning frame 27 to achieve positioning in the Y-axis direction. Then, the operator releases the hand. Under the action of the spring rod 13, the longitudinal frame 18 moves upward as a whole. At this time, the pressure head positioning frame 24 contacts the quick-change pressure head 7 and supports the quick-change pressure head 7.

[0040] In this state, manually disassemble the current quick-change pressure head 7. After the quick-change pressure head 7 is separated from the working end of the pressing cylinder 6, pull down the Y-axis platform 22 again and drive it to make a horizontal movement in the opposite direction (first pull the spring pin 26 out of the positioning frame 27). The pressure head positioning frame 24 drives the current quick-change pressure head 7 back to the working position.

[0041] Then the operator drives the quick-change pressure head 7 on another pressure head changing mechanism 17 to move to the end of the working shaft of the pressing cylinder 6. After manual connection, the pressure head changing mechanism 17 is returned to the initial position. Thus, the replacement between the first type of quick-change pressure head 7 and the second type of quick-change pressure head 7 is completed.
