Description

Technical Field

[0001] This utility model relates to the field of clamp manufacturing technology, specifically a clamp assembly device. Background Technology

[0002] In the critical assembly process of clamp arms and connecting shafts during clamp production, existing technologies have significant shortcomings: most small and medium-sized enterprises rely on manual placement of clamp arms, lacking dedicated positioning structures, which easily leads to clamp arm placement deviations and difficulties in aligning connecting parts. Shaft hole misalignment frequently occurs during shaft assembly, increasing assembly difficulty, easily damaging parts, and reducing the yield rate. Some semi-automatic equipment lacks effective guidance for dynamic load components, making them prone to displacement and wobbling during movement. Furthermore, the pressing mechanisms are mostly rigidly driven without buffer components, making the clamp arms susceptible to deformation from impact, affecting assembly accuracy. The drive mechanism layout is unreasonable, with some cylinders' overlapping movement directions easily interfering with each other, causing assembly jams. Moreover, the numerous manual interventions and high labor intensity make it difficult to ensure assembly consistency and meet the demands of mass production. Therefore, those skilled in the art provide a clamp assembly device to solve the problems mentioned in the background. Utility Model Content

[0003] The purpose of this invention is to provide a clip assembly device to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A clamp assembly device includes an assembly platform. A fixed platform is fixedly connected to the surface of the assembly platform, and a movable platform is slidably connected to the surface of the assembly platform. Both the fixed platform and the movable platform have placement grooves for placing clamp arms. The two sets of placement grooves are combined to form an A-shape. A pressing cylinder is fixedly connected to the surface of the assembly platform. A sleeve rod is fixedly connected to the movable end of the pressing cylinder. A movable groove is opened at one end of the sleeve rod. A movable rod is slidably connected to the inner side wall of the movable groove. One end of the movable rod is fixedly connected to the side wall of the movable platform.

[0005] Furthermore, a sliding groove is provided on the inner side wall of the movable groove, and a slider is slidably connected to the inner side wall of the sliding groove, and the side wall of the slider is fixedly connected to one end of the movable rod.

[0006] Furthermore, a spring is fixedly connected to the inner sidewall of the movable groove, with one end of the spring fixedly connected to one end of the movable rod.

[0007] Furthermore, a limit cylinder is fixedly connected to the surface of the assembly table, and an abutment plate is fixedly connected to the movable end of the limit cylinder. The abutment plate is used to limit the clamping arm.

[0008] Furthermore, a fixing frame is fixedly connected to the surface of the assembly table, a pressing cylinder is fixedly connected to the side wall of the fixing frame, a pressing rubber head is fixedly connected to the movable end of the pressing cylinder, and the pressing rubber head is matched with the shaft hole of the clamping arm.

[0009] Furthermore, the pressing cylinder, the limiting cylinder, and the pressing cylinder are perpendicular to each other.

[0010] By adopting the above technical solution Compared with the prior art, the beneficial effects of this utility model are: 1. The A-shaped placement slot can accurately match the shape of the clamping arm for initial positioning. Combined with the abutment plate driven by the limit cylinder, the clamping arm can be horizontally fixed, effectively preventing the clamping arm from shifting during placement and assembly, reducing positioning deviation from the source. At the same time, the slide and slider provide stable guidance for the sliding of the moving stage, ensuring accurate clamping arm docking trajectory. The spring in the movable slot can also buffer the pressing impact force, preventing the clamping arm from being damaged due to excessive force. In addition, the precise fit between the pressing head and the clamping arm shaft hole further ensures that the connecting shaft is pressed in place, greatly improving assembly accuracy and parts integrity rate, and ensuring product quality consistency.

[0011] 2. The vertical arrangement of the pressing cylinder, limiting cylinder, and downward pressing cylinder in pairs avoids interference between the various driving actions, allowing the clamping arm positioning, docking, pressing and other processes to proceed in an orderly manner, reducing assembly delays. The automated cylinder drive replaces traditional manual operation, which not only reduces labor intensity but also significantly improves production efficiency, adapting to the needs of mass production. In addition, the cooperation between the slide and the slider can reduce component wear and extend the service life of the device. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0015] Please see Figures 1-4This utility model provides an embodiment of a clamp assembly device, including an assembly platform 1. A fixed platform 2 is fixedly connected to the surface of the assembly platform 1, and a movable platform 3 is slidably connected to the surface of the assembly platform 1. Both the fixed platform 2 and the movable platform 3 have placement grooves 4 for placing clamp arms, and the two sets of placement grooves 4 are combined to form an A-shape. A pressing cylinder 5 is fixedly connected to the surface of the assembly platform 1. A sleeve rod 6 is fixedly connected to the movable end of the pressing cylinder 5. A movable groove 7 is formed at one end of the sleeve rod 6. A movable rod 10 is slidably connected to the inner wall of the movable groove 7. One end of the movable rod 10 is fixedly connected to the side wall of the movable platform 3. A sliding groove 8 is formed on the inner wall of the movable groove 7, and the inner wall of the sliding groove 8 is slidably connected to... There is a slider 9, and the side wall of the slider 9 is fixedly connected to one end of the movable rod 10. A spring 11 is fixedly connected to the inner side wall of the movable groove 7, and one end of the spring 11 is fixedly connected to one end of the movable rod 10. A limit cylinder 12 is fixedly connected to the surface of the assembly table 1. An abutment plate 13 is fixedly connected to the movable end of the limit cylinder 12. The abutment plate 13 is used to limit the clamping arm. A fixing frame 14 is also fixedly connected to the surface of the assembly table 1. A pressing cylinder 15 is fixedly connected to the side wall of the fixing frame 14. A pressing head 16 is fixedly connected to the movable end of the pressing cylinder 15, and the pressing head 16 fits into the shaft hole of the clamping arm. The pressing cylinder 5, the limit cylinder 12 and the pressing cylinder 15 are perpendicular to each other.The two clamping arms of the clamp are placed into the placement slots 4 of the fixed platform 2 and the moving platform 3 on the surface of the assembly table 1, respectively. Since the two sets of placement slots 4 are combined into an A-shape, they can accurately match the shape of the clamping arms and achieve the initial posture positioning of the clamping arms. The limiting cylinder 12 is activated, and its movable end drives the abutment plate 13 to move towards the clamping arm until the abutment plate 13 is tightly attached to one end of the clamping arm, thus limiting the clamping arm and preventing it from shifting during subsequent assembly. Then, the pressing cylinder 5 is activated, and its movable end pushes the sleeve rod 6 to move. The sleeve rod 6 drives the moving platform 3 to slide along the surface of the assembly table 1 towards the fixed platform 2 through the movable rod 10 on the inner side. During this process, the sliding groove 8 on the inner side of the movable slot 7 cooperates with the slider 9 to provide guidance for the movement of the movable rod 10, ensuring the stable sliding trajectory of the moving platform 3. Simultaneously, the spring 11 in the movable groove 7 undergoes elastic deformation as the movable rod 10 moves, providing a certain amount of spring pressure to prevent excessive impact from the moving platform 3 from damaging the clamping arms, until the connection points of the two clamping arms are aligned. At this point, the pressing cylinder 15 is activated. Because the pressing cylinder 5, the limiting cylinder 12, and the pressing cylinder 15 are perpendicular to each other, the movable end of the pressing cylinder 15 drives the pressing rubber head 16, which is engaged with the shaft hole of the clamping arm, to move vertically downward, precisely pressing the connecting shaft into the shaft hole of the two clamping arms, completing the clamp assembly. After assembly, each cylinder resets, and the moving platform 3 returns to its initial position so that the finished product can be removed for the next round of assembly. The shaped placement groove 4 can accurately match the shape of the clamping arm to achieve initial positioning. Combined with the abutment plate 13 driven by the limit cylinder 12, it can horizontally fix the clamping arm, effectively preventing displacement during placement and assembly, reducing positioning deviation from the source. Simultaneously, the sliding groove 8 and slider 9 provide stable guidance for the sliding of the moving stage 3, ensuring accurate clamping trajectory. The spring 11 in the movable groove 7 can also buffer the impact of pressing, preventing damage to the clamping arm due to excessive force. Furthermore, the precise fit between the pressing head 16 and the clamping arm shaft hole further ensures the press-fitting of the connecting shaft. The automated cylinder drive significantly improves assembly precision and parts integrity, ensuring consistent product quality. The perpendicular arrangement of the pressing cylinder 5, limit cylinder 12, and pressing cylinder 15 prevents interference between drive actions, allowing the clamping arm positioning, docking, and pressing processes to proceed smoothly and efficiently, reducing assembly delays. The automated cylinder drive replaces traditional manual operation, reducing labor intensity and significantly improving production efficiency, making it suitable for mass production needs. Furthermore, the cooperation between the slide groove 8 and the slider 9 reduces component wear and extends the device's lifespan.

[0016] During operation, the two clamping arms of the clamp are placed into the placement slots 4 of the fixed stage 2 and the moving stage 3 on the surface of the assembly table 1, respectively. Since the two sets of placement slots 4 form an A-shape, they can precisely match the shape of the clamping arms, achieving initial positioning of the clamping arms. The limiting cylinder 12 is activated, its movable end driving the abutment plate 13 towards the clamping arm until the abutment plate 13 is tightly fitted with one end of the clamping arm, limiting the clamping arm and preventing displacement during subsequent assembly. Then, the pressing cylinder 5 is activated, its movable end pushing the sleeve rod 6 to move. The sleeve rod 6, through the inner movable rod 10, drives the moving stage 3 to slide along the surface of the assembly table 1 towards the fixed stage 2. During this process, the sliding groove 8 and the slider 9 on the inner side of the movable slot 7 cooperate to guide the movement of the movable rod 10, ensuring a stable sliding trajectory of the moving stage 3. Simultaneously, the spring 11 in the movable groove 7 undergoes elastic deformation as the movable rod 10 moves, providing a certain spring pressure to prevent excessive impact from the moving platform 3 from damaging the clamping arms. This continues until the connection points of the two clamping arms are aligned. At this point, the pressing cylinder 15 is activated. Since the pressing cylinder 5, the limiting cylinder 12, and the pressing cylinder 15 are perpendicular to each other, the movable end of the pressing cylinder 15 drives the pressing rubber head 16, which is engaged with the shaft hole of the clamping arm, to move vertically downward, precisely pressing the connecting shaft into the shaft hole of the two clamping arms, thus completing the clamp assembly. After assembly, each cylinder is reset, and the moving platform 3 returns to its initial position so that the finished product can be removed for the next round of assembly.

[0017] The A-shaped placement slot 4 precisely matches the shape of the clamping arm for initial positioning. Combined with the abutment plate 13 driven by the limit cylinder 12, it horizontally fixes the clamping arm, effectively preventing displacement during placement and assembly, thus reducing positioning deviations from the outset. Simultaneously, the slide groove 8 and slider 9 provide stable guidance for the sliding of the moving stage 3, ensuring accurate clamping trajectory. The spring 11 within the movable slot 7 also buffers the impact of pressing, preventing damage to the clamping arm due to excessive force. Furthermore, the precise fit between the pressing head 16 and the clamping arm shaft hole further ensures the secure press-fit of the connecting shaft. The system is well-positioned, significantly improving assembly accuracy and parts integrity, ensuring consistent product quality. The vertical arrangement of the pressing cylinder 5, the limiting cylinder 12, and the pressing cylinder 15 in pairs avoids interference between the various driving actions, allowing the clamping arm positioning, docking, pressing, and other processes to proceed in an orderly manner, reducing assembly delays. The automated cylinder drive replaces traditional manual operation, reducing labor intensity and significantly improving production efficiency, making it suitable for mass production needs. In addition, the cooperation between the slide groove 8 and the slider 9 reduces component wear and extends the service life of the device.
