Description
Hollow aluminum profile structure Technical Field
[0001] This application relates to the field of aluminum profiles, specifically to a hollow aluminum profile structure. Background Technology
[0002] As society's demand for and emphasis on automotive products increases, the level of automation in automotive body-in-white welding production lines is also improving, with the fundamental principles being high flexibility, high density, and lightweight design.
[0003] In automated production lines for welding body-in-white, robotic arms are equipped with various tools, among which grippers are the main tools for handling body parts and often bear a huge workload; they handle body parts, grip parts for gluing, and perform welding repairs, etc. To cope with these working environments, designers have designed grippers with various frame types. The grippers currently available on the market are generally divided into welded frame grippers and octagonal tube frame grippers.
[0004] Existing welded frame grippers are characterized by high strength, but they are heavy, limiting robot operating speed. Once processed, they can only be disassembled or discarded entirely. Octagonal tube frame grippers are lightweight, but relatively weak. They require more material to reinforce the frame, making installation more complex and increasing the overall size of the gripper. This affects production efficiency and debugging difficulty. Currently, there is no gripper frame that combines high strength, high flexibility, and high lightweight. Summary of the Invention
[0005] To overcome the shortcomings of the prior art, embodiments of the present invention provide a hollow aluminum profile structure to solve the problem that there is no gripper tool frame in the existing processing and production technology that combines high strength, high flexibility and high lightweight.
[0006] On one hand, embodiments of the present invention provide a hollow aluminum profile structure, comprising:
[0007] Hollow profile and connecting assembly, the connecting assembly being connected to the hollow profile, the hollow profile having multiple connecting slots, the connecting assembly being used to assemble multiple hollow profiles through the multiple connecting slots.
[0008] It should be noted that the connecting components include an installation structure with matching connecting slots. When assembling multiple hollow profiles, according to the requirements of the target gripper tool frame, a number of hollow profiles can be assembled by connecting components connected to the hollow profiles and using connecting slots on other hollow profiles. Finally, the hollow profiles are installed and secured with screws and other detachable fasteners to obtain the target gripper tool frame.
[0009] It should be further explained that when using screws or other detachable fasteners to install and secure the hollow profiles, the connecting components and the hollow profiles are provided with corresponding parts or structures for installing screws or other detachable fasteners, such as positioning holes for screws; specifically, positioning holes of the same diameter are provided on both the connecting components and the hollow profiles to cooperate with screws or other detachable fasteners to install and secure the hollow profiles, ensuring the connection strength between the hollow profiles.
[0010] In this solution, multiple hollow profiles can be assembled using connecting components according to the requirements of the target gripper tool frame. This is achieved by installing the mounting structure on the connecting components into the connecting grooves on the hollow profiles and pushing them to the target position. Finally, the connecting components are fixed to complete the assembly of multiple hollow profiles. Furthermore, when it is necessary to change the structure of the target gripper tool frame, the original gripper tool frame can be directly disassembled into multiple hollow profiles and reassembled according to the new target gripper tool frame. Compared with existing gripper tool frames, this solution combines higher strength, higher flexibility, and higher lightweight characteristics.
[0011] In one embodiment, the hollow profile includes a square profile with a hollow center and a square composite profile composed of multiple hollow connecting profiles.
[0012] In this solution, both the square profiles and connecting profiles are designed as hollow structures in the middle, which can effectively reduce the weight of the square profiles and connecting profiles and improve the overall lightweighting of the hollow profiles. The square in the square profiles and square composite profiles refers to the fact that the cross-sectional shape of the two types of profiles is square, and the square design facilitates assembly with other square composite profiles.
[0013] In one embodiment, the square profile is located in the middle of the square composite profile, and a plurality of connecting profiles are connected to the square profile and located on the side of the square composite profile.
[0014] In one embodiment, two adjacent connecting profiles together with the square profile form the connecting groove.
[0015] It should be noted that multiple connecting profiles are specifically connected to the side of the square profile, and two adjacent connecting profiles together with the surface of the square profile form a connecting groove, that is, there are a total of four connecting profiles connected to the corners of the cross-section of the square profile.
[0016] In this solution, the square profiles and connecting profiles are arranged in this way, so that the surface of the square profiles has connecting grooves without the addition of other external structures, and multiple square composite profiles can be assembled by cooperating with the connecting components through the connecting grooves.
[0017] In one embodiment, the hollow profile further includes a rectangular composite profile formed by combining a rectangular profile with a hollow center, the square profile, and the connecting profile.
[0018] In this solution, the rectangular profiles, square profiles, and connecting profiles are all hollow panels in the middle, which can effectively reduce the weight of the square profiles and connecting profiles and improve the overall lightweighting of the hollow profiles; the rectangular profiles, square profiles, and connecting profiles are all hollow structures in the middle, which can effectively reduce the lightweighting of the rectangular profiles, square profiles, and connecting profiles; the "rectangular" in the rectangular profiles and rectangular combination profiles refers to the rectangular cross-sectional shape of the aforementioned two types of profiles, which is designed to facilitate assembly with other rectangular combination profiles.
[0019] In one embodiment, the rectangular profile is located in the middle of the rectangular composite profile, the square profile is connected to the rectangular profile, and the connecting profile is connected to the square profile.
[0020] In one embodiment, two adjacent connecting profiles, together with the rectangular or square profile, form the connecting groove.
[0021] It should be noted that the square profile is specifically connected to the top and bottom of the rectangular profile, and the connecting profile is specifically connected to the upper corner of the upper square profile and the lower corner of the lower square profile. Furthermore, two adjacent connecting profiles together with the rectangular or square profiles form a connecting groove, that is, there are a total of four connecting profiles connected to the corners of the rectangular composite profile cross-section.
[0022] In this solution, the square profile, rectangular profile, and connecting profile are arranged in this way, so that the surface of the rectangular profile has a connecting groove without the addition of other external structures, and the assembly of multiple rectangular combined profiles can be completed through the cooperation of the connecting groove and the connecting component.
[0023] In one of the designs, four connecting profiles are respectively connected to the corners of the square profile.
[0024] In one embodiment, the connecting assembly includes a connecting body and a sliding member. The sliding member is mounted on the connecting body, and one end of the sliding member extends out of the connecting body. The extended end of the sliding member is adapted to the connecting groove. The sliding member cooperates with the connecting groove to realize the assembly of multiple hollow profiles.
[0025] It should be noted that the sliding component specifically includes a screw and a T-nut. The protruding end of the screw is a T-nut that is threadedly connected to the screw. The T-nut is a T-shaped structure that fits into the connecting groove.
[0026] In this solution, the connecting component can move freely in the connecting groove via a slider mounted on the connecting body. Once it reaches the target position, it can be installed and tightened using screws or other removable fasteners. When it is necessary to change the installation position of the connecting component, the screws or other removable fasteners can be removed directly, and the slider can be pushed to move again in the connecting groove to the new target position. Then, the screws or other removable fasteners can be used again to install and tighten it.
[0027] In one embodiment, the connecting body includes a first connecting surface and a second connecting surface, the first connecting surface and the second connecting surface being connected to different hollow profiles respectively.
[0028] In one embodiment, both the hollow profile and the connecting assembly are provided with positioning holes, which are used to install other external equipment or connecting structures.
[0029] It should be noted that, with the cooperation of the sliding member and the connecting groove, the connecting body can drive the hollow profile connected to the first connecting surface to slide relative to the hollow profile connected to the second connecting surface, or drive the hollow profile connected to the second connecting surface to slide relative to the hollow profile connected to the first connecting surface, or fix the hollow profiles connected to the first connecting surface and the second connecting surface.
[0030] It should be noted that the driving mechanism that drives the hollow profile to slide is either a driving mechanism mounted on the gripper tool frame or an externally connected driving mechanism. The driving mechanism drives the corresponding connecting component to move along the connecting groove according to the needs of the actual processing flow, so as to move the corresponding hollow profile.
[0031] In this solution, when installing the connecting components, the hollow profiles that need to be moved and the hollow profiles that need to be fixed can be determined according to the requirements of the target gripper tool frame. Multiple hollow profiles are assembled into a gripper tool frame by using the positioning holes on the connecting components and the hollow profiles, along with detachable fasteners such as screws.
[0032] On the other hand, embodiments of the present invention provide a gripper frame comprising the hollow aluminum profile structure described above. Attached Figure Description

[0044] Please refer to Figures 1-6. In one embodiment, a hollow aluminum profile structure is provided, including:
[0045] Hollow profile 1 and connecting component 2, the connecting component 2 being connected to the hollow profile 1, the hollow profile 1 having a plurality of connecting grooves 14, the connecting component 2 being used to assemble a plurality of hollow profiles 1 through the plurality of connecting grooves 14.
[0046] It should be noted that the connecting component 2 includes an installation structure that adapts to the connecting slot 14. When assembling multiple hollow profiles 1, according to the requirements of the target gripper tool frame, the connecting component 2 connected to the hollow profile 1, in conjunction with the connecting slot 14 on other hollow profiles 1, can be used to assemble a number of hollow profiles 1. Finally, the hollow profiles 1 can be installed and fastened by detachable fasteners such as screws 221 to obtain the target gripper tool frame.
[0047] It should be further explained that when using detachable fasteners such as screws 221 to install and tighten the hollow profile 1, the connecting component 2 and the hollow profile 1 are provided with corresponding parts or structures for installing detachable fasteners such as screws 221, such as positioning holes 3 that are adapted to screws 221; specifically, positioning holes 3 of the same diameter are provided on both the connecting component 2 and the hollow profile 1 to cooperate with detachable fasteners such as screws 221 to install and tighten the hollow profile 1, ensuring the connection strength between the hollow profiles 1.
[0048] In this solution, multiple hollow profiles 1 can be assembled using connecting components 2 according to the requirements of the target gripper tool frame. This is achieved by installing the mounting structure on the connecting components 2 into the connecting grooves 14 on the hollow profiles 1 and pushing them to the target position. Finally, the connecting components 2 are fixed to complete the assembly of multiple hollow profiles 1. Furthermore, when it is necessary to change the structure of the target gripper tool frame, the original gripper tool frame can be directly disassembled into multiple hollow profiles 1 and reassembled according to the new target gripper tool frame. Compared with the existing gripper tool frames, this solution has the characteristics of high strength, high flexibility, and high lightweight.
[0049] In one embodiment, the hollow profile 1 includes a square composite profile 111 composed of a square profile 111 that is hollow in the middle and a plurality of connecting profiles 12 that are hollow in the middle.
[0050] In this design, both the square profile 111 and the connecting profile 12 are designed as hollow structures in the middle, which can effectively reduce the weight of the square profile 111 and the connecting profile 12 and improve the overall lightweighting of the hollow profile 1. The square shape in the square profile 111 and the square composite profile 11 refers to the fact that the cross-sectional shape of the two profiles is square. The square design facilitates assembly with other square composite profiles 11 or other types of profiles.
[0051] In one embodiment, the square profile 111 is located in the middle of the square composite profile 11, and a plurality of connecting profiles 12 are connected to the square profile 111 and located on the side of the square composite profile 11.
[0052] In one embodiment, two adjacent connecting profiles 12 and the square profile 111 together form the connecting groove 14.
[0053] It should be noted that multiple connecting profiles 12 are specifically connected to the side of the square profile 111, and two adjacent connecting profiles 12 and the surface of the square profile 111 together form a connecting groove 14, that is, there are a total of four connecting profiles 12 connected to the corners of the cross-sectional view of the square profile 111.
[0054] In this solution, the square profile 111 and the connecting profile 12 are arranged in such a way that the surface of the square profile 111 has a connecting groove 14 without the addition of other external structures, and the assembly of multiple square composite profiles 11 can be completed through the cooperation of the connecting groove 14 and the connecting component 2.
[0055] In one embodiment, the hollow profile 1 further includes a rectangular composite profile 13 formed by combining the centrally hollow rectangular profile 131, the square profile 111, and the connecting profile 12.
[0056] In this design, the rectangular profile 131, the square profile 111, and the connecting profile 12 are all hollow panels in the middle, which can effectively reduce the weight of the square profile 111 and the connecting profile 12, and improve the overall lightweighting of the hollow profile 1; the rectangular profile 131, the square profile 111, and the connecting profile 12 are all hollow structures in the middle, which can effectively reduce the lightweighting of the rectangular profile 131, the square profile 111, and the connecting profile 12; the rectangle in the rectangular profile 131 and the rectangular combined profile 13 refers to the rectangular cross-sectional shape of the aforementioned two profiles, which is designed to facilitate assembly with other rectangular combined profiles 13.
[0057] In one embodiment, the rectangular profile 131 is located in the middle of the rectangular composite profile 13, the square profile 111 is connected to the rectangular profile 131, and the connecting profile 12 is connected to the square profile 111.
[0058] In one embodiment, two adjacent connecting profiles 12 together with the rectangular profile 131 or the square profile 111 form the connecting groove 14.
[0059] It should be noted that the square profile 111 is specifically connected to the top and bottom of the rectangular profile 131, and the connecting profile 12 is specifically connected to the upper corner of the upper square profile 111 and the lower corner of the lower square profile 111. Two adjacent connecting profiles 12, together with the rectangular profile 131 or the square profile 111, form a connecting groove 14. That is, there are a total of four connecting profiles 12 connected to the corners of the cross-section of the rectangular composite profile 13.
[0060] In this solution, the square profile 111, rectangular profile 131 and connecting profile 12 are arranged in such a way that the rectangular profile 131 has a connecting groove 14 on its surface without the addition of other external structures, and the assembly of multiple rectangular combined profiles 13 can be completed through the cooperation of the connecting groove 14 and the connecting component 2.
[0061] In one embodiment, the connecting component 2 includes a connecting body 21 and a slider 22. The slider 22 is mounted on the connecting body 21, and one end of the slider 22 extends out of the connecting body 21. The extended end of the slider 22 is adapted to the connecting groove 14. The slider 22 cooperates with the connecting groove 14 to realize the assembly of multiple hollow profiles 1.
[0062] It should be noted that the sliding component 22 specifically includes a screw 221 and a T-nut 222. The protruding end of the screw 221 is a T-nut 222 that is threadedly connected to the screw 221. The T-nut 222 is a T-shaped structure that fits the connecting groove 14.
[0063] In this solution, the connecting component 2 can move freely in the connecting groove 14 via the sliding member 22 installed on the connecting body 21. After reaching the target position, it can be installed and tightened using detachable fasteners such as screws 221. When it is necessary to change the installation position of the connecting component 2, the detachable fasteners such as screws 221 can be directly removed, and the sliding member 22 can be pushed to move again in the connecting groove 14 to the new target position. Then, it can be installed and tightened again using detachable fasteners such as screws 221.
[0064] In one embodiment, the connecting body 21 includes a first connecting surface 211 and a second connecting surface 212, the first connecting surface 211 and the second connecting surface 212 respectively connecting different hollow profiles 1.
[0065] In one embodiment, both the hollow profile 1 and the connecting component 2 are provided with positioning holes 3, which are used to install other external equipment or connecting structures.
[0066] It should be noted that, with the cooperation of the sliding member 22 and the connecting groove 14, the connecting body 21 can drive the hollow profile 1 connected to the first connecting surface 211 to slide relative to the hollow profile 1 connected to the second connecting surface 212, or drive the hollow profile 1 connected to the second connecting surface 212 to slide relative to the hollow profile 1 connected to the first connecting surface 211, or fix the hollow profile 1 connected to the first connecting surface 211 and the second connecting surface 212.
[0067] It should be noted that the driving mechanism that drives the hollow profile 1 to slide is either a driving mechanism mounted on the gripper tool frame or an externally connected driving mechanism. The driving mechanism drives the corresponding connecting component 2 to move along the connecting groove 14 according to the needs of the actual processing flow, so as to drive the corresponding hollow profile 1 to move.
[0068] It should be noted that the dimensions of the connecting components 2 installed on the square composite profile 11 and the rectangular composite profile 13 correspond to the dimensions of the square composite profile 11 and the rectangular composite profile 13, respectively, and the protruding ends of the sliding parts 22 in the connecting components 2 correspond to the positions of the connecting grooves 14 on the square composite profile 11 and the rectangular composite profile 13.
[0069] In this solution, when installing the connecting component 2, the hollow profile 1 that needs to be moved and the hollow profile 1 that needs to be fixed can be determined according to the requirements of the target gripper tool frame. Multiple hollow profiles 1 can be assembled into a gripper tool frame by using the connecting component 2 and the positioning holes 3 on the hollow profile 1 in conjunction with detachable fasteners such as screws 221.
