Technical Field
[0001] This utility model relates to the technical field of hydrogen fuel cell testing devices, specifically a pressure resistance testing device for hydrogen fuel cell production. Background Technology
[0002] During the production process of hydrogen fuel cells, a hydrogen fuel cell pressure testing device is needed to test the pressure intensity that the fuel cell can withstand.
[0003] For example, announcement number CN221199188U, entitled "A Hydrogen Fuel Cell Pressure Resistance Testing Device", includes a frame, a workbench, a support base, a turntable, a fuel cell, a moving positioning component, and a stretching and flipping component. The frame is U-shaped and is fixed upside down on the workbench. The moving positioning component is located on the top inner side of the frame, and the stretching and flipping component is located inside the moving positioning component. The moving positioning component includes a moving frame, an electric telescopic rod, a motor box, a strip box, a first motor, a screw, a threaded sleeve, a connecting rod, a moving clamping plate, and a fixed clamping plate. The stretching and flipping component includes a rotating shaft, a second motor, a winding wheel, and a connecting rope.
[0004] While the existing hydrogen fuel cell pressure resistance testing device has the function of clamping and limiting the fuel cell, the clamping and limiting structure can only clamp and limit one fuel cell at a time, which results in low efficiency. Therefore, it does not meet the current requirements. In response, a pressure resistance testing device for hydrogen fuel cell production is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a pressure resistance testing device for hydrogen fuel cell production, so as to solve the problem mentioned in the background art that the existing hydrogen fuel cell pressure resistance testing devices cannot perform clamping and pressure resistance testing on multiple fuel cells.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a pressure resistance testing device for hydrogen fuel cell production, comprising: a testing platform, two symmetrically mounted placement platforms for placing the fuel cell to be tested are mounted on the upper left and right sides of the testing platform, a lead screw displacement module is mounted on one side of each of the two placement platforms, two sets of clamping and limiting components are mounted above the lead screw displacement modules, a driving assembly is mounted between the lead screw displacement modules, and a pressing assembly is mounted between the placement platforms.
[0007] Preferably, the lead screw displacement module includes a base, a forward threaded lead screw is installed inside the upper part of the base, a reverse threaded lead screw is installed at one end of the forward threaded lead screw, slide rails are provided on both sides of the forward threaded lead screw and the reverse threaded lead screw, and sliders are installed on the outer walls of the forward threaded lead screw and the reverse threaded lead screw.
[0008] Preferably, a cover plate is installed on the top of the base, and two sets of sliding openings are provided on the outer wall of the cover plate. A sliding platform is provided on the top of the cover plate, and the bottom of the sliding platform is connected to the slider by bolts.
[0009] Preferably, the drive assembly includes a first synchronous pulley and a second synchronous pulley respectively installed at the ends of the two sets of positive threaded screws, a synchronous belt is provided between the first synchronous pulley and the second synchronous pulley, and a drive motor is installed at one end of the first synchronous pulley.
[0010] Preferably, the clamping and limiting member includes an assembly frame mounted on the upper surface of the slide, and a limiting clamp is installed on the outer wall of the assembly frame.
[0011] Preferably, a rubber pad is provided on the outer wall of the limiting clamp.
[0012] Preferably, the pressing component includes a support frame, on the upper surface of which two sets of servo electric cylinders are symmetrically mounted, and a pressure plate is mounted on the telescopic end of each servo electric cylinder.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model drives the first synchronous wheel to rotate by a drive motor, so that the sliders on the positive thread screw and the negative thread screw can perform displacement operation. Since the screw adopts a positive and negative structure, the two sets of sliders can move closer and further away from each other. During this displacement, the clamping limiter will move together, thereby clamping and limiting the fuel cell, improving the stability of the fuel cell placement state. In addition, since the first synchronous wheel is connected to the second synchronous wheel through a synchronous belt, the clamping limiter at the other screw displacement module at the second synchronous wheel can perform clamping and limiting operation. The above structure can realize the clamping and displacement operation of the two fuel cells based on the drive component, effectively improving the stability of the fuel cell placement state and improving the detection efficiency.
[0015] (2) The assembly frame of this utility model serves to be combined with the slide table for installation. The limiting clamp is used to restrict the fuel cell. The rubber pad has anti-slip properties. After it comes into contact with the fuel cell, it can improve the anti-slip effect at that point and prevent it from shifting. At the same time, it prevents the limiting clamp from directly contacting the side of the fuel cell.
[0016] (3) The two sets of servo electric cylinders of this utility model perform pressure detection operations on the fuel cells placed on the two placement platforms respectively. By driving the servo electric cylinders, their extension ends extend downward, driving the pressure plate downward to apply downward pressure to the fuel cells. The pressure resistance performance of the fuel cells is detected by the magnitude of the applied downward pressure. Attached Figure Description

Detailed Implementation
[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Please see Figure 1-4This utility model provides an embodiment of a pressure resistance testing device for hydrogen fuel cell production, comprising: a testing platform 1, two symmetrically mounted placement platforms 3 for placing the fuel cells to be tested on the upper left and right sides of the testing platform 1, a screw displacement module 2 mounted on one side of each of the two placement platforms 3, two sets of clamping and limiting members 6 mounted above the screw displacement module 2, a drive assembly 4 mounted between the screw displacement modules 2, and a pressing assembly 5 mounted between the placement platforms 3. The screw displacement module 2 includes a base 201, a forward threaded screw 204 mounted inside the upper part of the base 201, a reverse threaded screw 205 mounted at one end of the forward threaded screw 204, slide rails 206 provided on both sides of the forward threaded screw 204 and the reverse threaded screw 205, and sliders 207 mounted on the outer walls of the forward threaded screw 204 and the reverse threaded screw 205. The drive assembly 4 includes a first synchronous pulley 402 and a second synchronous pulley 403 respectively mounted at the ends of the two sets of forward threaded screws 204. A synchronous belt 404 is provided between the first synchronous pulley 402 and the second synchronous pulley 403. A drive motor 401 is installed at one end of the first synchronous pulley 402. The drive motor 401 drives the first synchronous pulley 402 to rotate, causing the sliders 207 on the forward threaded screw 204 and the reverse threaded screw 205 to move. Since the screws adopt a forward and reverse structure, the two sets of sliders 207 will move closer and further apart. During this displacement, the clamping limit member 6 will move together, thereby clamping and limiting the fuel cell, improving the stability of the fuel cell placement. In addition, since the first synchronous pulley 402 is connected to the second synchronous pulley 403 through the synchronous belt 404, the second synchronous pulley 403 drives the clamping limit member 6 at the other screw displacement module 2 to perform clamping and limiting operations. The above structure can realize the clamping and displacement operation of two fuel cells based on the drive component 4, effectively improving the stability of the fuel cell placement and improving the detection efficiency.
[0024] Furthermore, such as Figure 3 As shown, a cover plate 202 is installed above the base 201. Two sets of sliding openings 203 are provided on the outer wall of the cover plate 202. A sliding table 208 is provided above the cover plate 202. The bottom of the sliding table 208 is connected to the slider 207 by bolts. The cover plate 202 serves to protect the internal parts. When the slider 207 slides, it will drive the upper sliding table 208 to slide together. The sliding table 208 is installed outside the cover plate 202 and moves at the strip-shaped sliding openings 203. The clamping and limiting member 6 is installed on the sliding table 208 and exposed to the outside, which facilitates the clamping and limiting operation of the external fuel cell.
[0025] Please see Figure 3The clamping and limiting component 6 includes an assembly frame 601 mounted on the upper surface of the slide table 208. A limiting clamp 602 is installed on the outer wall of the assembly frame 601, and a rubber pad 603 is provided on the outer wall of the limiting clamp 602. The assembly frame 601 serves to be combined and installed with the slide table 208. The limiting clamp 602 is used to limit the fuel cell. The rubber pad 603 has anti-slip properties. After it contacts the fuel cell, it can improve the anti-slip effect at that point and prevent it from shifting. At the same time, it prevents the limiting clamp 602 from directly contacting the side of the fuel cell.
[0026] Please see Figure 4 The pressure-reducing assembly 5 includes a support frame 501. Two sets of servo electric cylinders 502 are symmetrically mounted on the upper surface of the support frame 501. A pressure plate 503 is mounted on the telescopic end of the servo electric cylinder 502. The servo electric cylinder 502 is model LTW180. The two sets of servo electric cylinders 502 respectively perform pressure detection operations on the fuel cells placed on the two placement platforms 3. By driving the servo electric cylinder 502, its telescopic end extends downward, driving the pressure plate 503 to apply downward pressure to the fuel cell. The pressure resistance performance of the fuel cell is detected by the magnitude of the applied downward pressure.
