Description

Technical Field

[0001] The utility model belongs to the technical field of profiling jigs, in particular to an adsorption mechanism for a profiling jig. Background Art

[0002] During the manufacturing process of hydrogen fuel cell plates, a key step is to perform glue dispensing on the anode plate in the fuel cell plate. After the glue dispensing operation is completed, the cathode plate is tightly bonded to the anode plate to finally form a plate assembly product used in the hydrogen fuel cell. During the glue dispensing process on the plate, in order to ensure the accuracy and stability of the glue dispensing, a special jig is required to accurately position and firmly fix the plate. As an important tool to assist in controlling position or movement during the production process, the jig plays an indispensable role. After the existing battery plate is placed in the jig, it is necessary to use a cylinder to drive the jig rod to further compact the jig to achieve a more stable and precise fixing effect. This compacting operation can effectively prevent the plate from being offset or loosened during the glue dispensing and subsequent bonding process, thereby improving the reliability of the plate assembly.

[0003] Deficiencies of the existing contoured jig adsorption mechanism: In actual applications, the existing plate jigs are usually fixed directly on the dispensing equipment by screwing. When dispensing operations are required on battery plates of different models, the corresponding jig must be replaced. After replacing the appropriate jig, it is necessary to fix it again with screws. This process is also complicated and troublesome. It is necessary to carefully align the mounting holes and tighten the screws one by one to ensure the stability of the jig installation. Moreover, since the positions of the mounting holes of different jigs are often different, this means that when replacing the jig, not only the applicability of the jig must be considered, but also the jig whose mounting hole position is compatible with the mounting hole of the dispensing equipment must be carefully selected. Otherwise, even if the function of the jig meets the requirements, but the mounting holes do not match, it still cannot be installed and used smoothly, further increasing the difficulty and complexity of jig replacement. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a profiling fixture adsorption mechanism, comprising a workbench, a quick installation structure located at the bottom of the workbench, and an adsorption structure located in the middle of the workbench;

[0005] The quick installation structure includes a sliding block and a threaded sleeve assembled inside the sliding block, and a threaded rod threadedly connected to the inner wall of the threaded sleeve. A circular hole is opened inside the threaded rod, and the internal sliding connection of the circular hole is connected to a limiting cylinder. The inner wall of the limiting cylinder is opened with two through holes, and a hydraulic buffer rod is installed inside the through hole. The external sleeves of the two hydraulic buffer rods are provided with springs, and the two springs are fixedly connected to a circular slider on the side away from each other.

[0006] Preferably, a connecting rod is fixedly connected to the bottom of the limiting cylinder, and a locking ring is threadedly connected to the outside of the connecting rod.

[0007] Preferably, the top of the workbench is provided with two sliding grooves adapted for sliding with the sliding block, and the top of the threaded rod is fixedly connected with a turntable.

[0008] Preferably, screw holes distributed equidistantly are provided at the bottom of the workbench and on both sides of the two sliding grooves, and the sliding block is connected to the threaded holes through screws and locked to the bottom surface of the workbench.

[0009] Preferably, the adsorption structure comprises three equidistantly distributed mounting holes, and adsorption blocks are installed inside the mounting holes.

[0010] Preferably, a jig is provided above the workbench, and four mounting columns are provided on the top of the jig, and inner walls of the mounting columns are provided with limiting grooves adapted to the circular slider.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] The utility model adopts the design of the quick installation structure, so that the fixture only needs to be placed on the top of the workbench during installation, and then the turntable is manually rotated. The rotation of the turntable drives the threaded rod to start rotating. Since the threaded rod is limited by the threaded sleeve, it will move upward along the threaded sleeve while rotating. As the threaded rod moves upward, it drives the limiting cylinder to move upward synchronously, and then continues to apply force by pushing the connecting rod, prompting the limiting cylinder to continue to move upward. During this continuous upward movement, when the circular slider inside the limiting cylinder encounters the limiting groove on the installation column, the elastic potential energy stored in the spring is quickly released, and the circular slider is forcefully ejected, so that the circular slider is embedded in the limiting groove, thereby successfully and firmly installing the limiting cylinder in the installation column, and finally achieving the quick installation effect of the fixture. The design of this quick installation structure not only saves installation time and labor costs, but also improves the accuracy and stability of installation, bringing great convenience to production work.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the utility model provides a profiling fixture adsorption mechanism, comprising a workbench 1, a quick installation structure 2 located at the bottom of the workbench 1, and an adsorption structure 3 located in the middle of the workbench 1;

[0022] The quick installation structure 2 includes a sliding block 21 and a threaded sleeve 22 assembled inside the sliding block 21, and a threaded rod 23 threadedly connected to the inner wall of the threaded sleeve 22. A circular hole is opened inside the threaded rod 23, and a limiting cylinder 24 is slidably connected inside the circular hole. Two through holes are opened on the inner wall of the limiting cylinder 24, and a hydraulic buffer rod 25 is installed inside the through hole. The outer sleeves of the two hydraulic buffer rods 25 are provided with springs 26, and the two springs 26 are fixedly connected to a circular slider 27 on the side away from each other.

[0023] The above solution is adopted: through the design of the quick installation structure 2, the jig 4 only needs to be placed on the workbench 1 during installation, and then the turntable 231 is manually rotated. The rotation of the turntable 231 drives the threaded rod 23 to start rotating. Since the threaded rod 23 is limited by the threaded sleeve 22, it will move upward along the threaded sleeve 22 while rotating. As the threaded rod 23 moves upward, it drives the limiting cylinder 24 to move upward synchronously. Then, by pushing the connecting rod 241, the force is continued to be applied to prompt the limiting cylinder 24 to continue to move upward. During this continuous upward movement, when the circular slider 27 inside the limiting cylinder 24 encounters the limiting groove on the mounting column 41, the elastic potential energy stored in the spring 26 is quickly released, and the circular slider 27 is forcefully ejected, so that the circular slider 27 is embedded in the limiting groove, thereby successfully and firmly installing the limiting cylinder 24 in the mounting column 41, and finally achieving the quick installation effect of the jig 4. The design of this quick installation structure 2 not only saves installation time and labor costs, but also improves the accuracy and stability of installation, bringing great convenience to production work.

[0024] like Figures 1 to 6 As shown, the bottom of the limiting cylinder 24 is fixedly connected to a connecting rod 241, the external thread of the connecting rod 241 is connected to a locking ring 242, the top of the workbench 1 is provided with two sliding grooves that slide with the sliding block 21, and the top of the threaded rod 23 is fixedly connected to a turntable 231.

[0025] The above solution is adopted: the bottom of the limiting cylinder 24 is fixedly connected to the top of the connecting rod 241, and the connecting rod 241 is locked to the bottom of the turntable 231 by the locking ring 242. A through hole is opened at the top of the sliding block 21, and the threaded sleeve 22 is installed inside the through hole.

[0026] like Figures 1 to 6 As shown, equidistantly distributed screw holes are provided at the bottom of the workbench 1 and on both sides of the two slide grooves. The sliding block 21 is connected to and locked on the bottom surface of the workbench 1 through screws and threaded holes. The adsorption structure 3 includes three equidistantly distributed mounting holes 31, and an adsorption block 32 is installed inside the mounting hole 31.

[0027] According to the above solution, the three adsorption blocks 32 are distributed in a linear array, and the electrode plates can be adsorbed by the adsorption blocks 32 .

[0028] like Figures 1 to 6 As shown, a fixture 4 is provided above the workbench 1 , and four mounting columns 41 are provided on the top of the fixture 4 . The inner walls of the mounting columns 41 are provided with limiting grooves adapted to the circular slider 27 .

[0029] With the above solution, the limiting groove cooperates with the circular slider 27 , and the circular slider 27 can be stuck in the limiting groove under the action of the spring 26 .

[0030] The working principle and use process of this utility model:

[0031] First, place the fixture 4 to be installed on the workbench 1 so that it is in a preliminary position. Then manually rotate the turntable 231. When the turntable 231 rotates, it drives the threaded rod 23 to start rotating. At this time, since the threaded rod 23 is limited by the threaded sleeve 22, during the rotation process, the threaded rod 23 cannot move laterally and can only move upward along the thread structure of the threaded sleeve 22. As the threaded rod 23 moves upward, it drives the limit cylinder 24 connected to it to move upward synchronously. On this basis, by pushing the connecting rod 241 Continue to apply upward force so that the limit cylinder 24 can continue to move upward. During the process of the limit cylinder 24 continuing to move upward, special attention should be paid to the circular slider 27 inside it. When the circular slider 27 contacts the limit groove on the mounting column 41, the elastic potential energy stored in the spring 26 will be released instantly, and the circular slider 27 will be ejected quickly and forcefully, so that it can be accurately embedded in the limit groove. When the circular slider 27 is successfully embedded in the limit groove, it means that the limit cylinder 24 is firmly installed in the mounting column 41. At this point, the installation of the jig 4 is successfully completed.
