Description

Technical Field

[0001] This utility model relates to the field of robot gripper technology, and in particular to an adjustable steel coil support robot gripper. Background Technology

[0002] Steel coil support racks are key equipment in steel logistics and processing, used for the safe support, transportation and storage of heavy steel coils.

[0003] After production, steel coils are wound up using a coil reel and then gripped by a machine gripper onto a coil support for support, fixation, storage, and transportation. However, different steel coils vary greatly in weight and inner diameter, requiring different sizes of machine grippers to be selected based on the coil's diameter. The mechanical gripper then clamps and holds the coiled steel coil along its sides, placing it on the coil support. However, the smooth sidewalls of the coiled steel coil make it easy for the coil to slide downwards on the gripper when gripped, causing it to slip out of the gripper's limit and fall, resulting in damage to the coil and posing a safety hazard to nearby workers. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing technologies cannot be applied to clamping steel coils of different specifications, and to propose an adjustable steel coil support robot gripper.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable steel coil support robot gripper includes a tray, on which a support rod is fixedly mounted. A sliding ring is slidably fitted on the outer wall of the support rod, and a force-bearing rod is fixedly mounted on the outer wall of the sliding ring. A rotating arm is fixedly mounted on the other end of the force-bearing rod, and a first hydraulic rod is fixedly mounted on the bottom end of the rotating arm. An installation plate is integrally mounted on the output end of the first hydraulic rod. Three equidistant circumferentially arranged connecting columns are fixedly mounted on the bottom end of the installation plate, and a limit plate is fixedly mounted on the bottom end of the three connecting columns. The limit plate has three circumferentially equally spaced second sliding grooves, and sliding blocks are slidably arranged in each of the three second sliding grooves. A bearing bracket for clamping the steel coil is fixedly mounted on the bottom end of each of the three sliding blocks.

[0007] Preferably, a limiting rod is fixedly installed on the limiting plate relative to the three connecting columns. A first sliding groove is provided in the limiting rod, and a second hydraulic rod is fixedly installed in the first sliding groove. A movable plate is fixedly installed at the bottom end of the second hydraulic rod. Three transmission rods that are circumferentially divided are rotatably installed on the side wall of the movable plate through a rotating seat.

[0008] Preferably, the upper ends of the three sliding blocks are fixedly connected to the three transmission rods respectively through rotating seats, the three bearing brackets are all U-shaped structures, and each of the three bearing brackets is provided with a conical block.

[0009] Preferably, each of the three bearing brackets is fixedly mounted with a hydraulic cylinder, and each of the three hydraulic cylinders has a clamping plate slidably mounted on its output end within the bearing bracket.

[0010] Preferably, a limiting frame is rotatably mounted on the upper end of the support rod, and the other end of the rotating arm is fixedly mounted in the limiting frame via a fixed shaft.

[0011] Preferably, the support rod has an installation groove, in which a drive motor is fixedly installed, and the output end of the drive motor is fixedly connected to the limiting frame.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. This utility model adjusts the height of the moving plate in the first sliding groove by extending and retracting the second hydraulic rod, reducing the distance between the three bearing brackets, and making the three bearing brackets support the steel coil, preventing the steel coil from sliding down under the limit of the mechanical gripper, and clamping steel coils of different sizes, making it easy to clamp and place steel coils of different sizes on the steel coil bracket.

[0014] 2. This utility model adjusts the height of the clamping plate on the bearing bracket by extending and retracting the hydraulic cylinder, so that the clamping plate limits and fixes the steel coil, making it easier to transport the steel coil more stably when the limit frame rotates.

[0020] 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.

[0021] Reference Figures 1-4 An adjustable steel coil support robot gripper includes a tray 1, a support rod 2 fixedly mounted on the tray 1, a sliding ring 3 slidably sleeved on the outer wall of the support rod 2, a force-bearing rod 4 fixedly mounted on the outer wall of the sliding ring 3, a rotating arm 6 fixedly mounted on the other end of the force-bearing rod 4, a first hydraulic rod 7 fixedly mounted on the bottom end of the rotating arm 6, an installation plate 8 integrally mounted on the output end of the first hydraulic rod 7, three equidistant circumferentially arranged connecting columns 9 fixedly mounted on the bottom end of the installation plate 8, and a limit plate 10 fixedly mounted on the bottom end of the three connecting columns 9, and three circumferentially equally spaced second sliding grooves 17 opened on the limit plate 10, each of the three second sliding grooves 17 having a sliding block 16 slidably arranged in each of the three sliding grooves 17, and a bearing bracket 18 for clamping the steel coil fixedly mounted on the bottom end of each of the three sliding blocks 16.

[0022] A limiting rod 11 is fixedly installed on the limiting plate 10 between the three connecting columns 9. A first sliding groove 12 is provided in the limiting rod 11, and a second hydraulic rod 13 is fixedly installed in the first sliding groove 12. A movable plate 14 is fixedly installed at the bottom end of the second hydraulic rod 13. Three transmission rods 15 are rotatably installed on the side wall of the movable plate 14 through a rotating seat.

[0023] The upper ends of the three sliding blocks 16 are fixedly connected to the three transmission rods 15 respectively through rotating seats. The three bearing brackets 18 are all U-shaped structures, and each of the three bearing brackets 18 is provided with a conical block. When the three bearing brackets 18 move towards each other through the conical blocks, it is easy for the bottom end of the bearing bracket 18 to be inserted into the bottom end of the steel coil to support the steel coil.

[0024] Hydraulic cylinders 19 are fixedly installed on each of the three bearing brackets 18. Clamping plates 20, which are slidably installed inside the bearing brackets 18, are fixedly installed on the output ends of the three hydraulic cylinders 19. The steel coil is clamped by the clamping plates 20, making the steel coil transport more stably.

[0025] The upper end of the support rod 2 is rotatably mounted with a limit frame 5, and the other end of the rotating arm 6 is fixedly mounted in the limit frame 5 through a fixed shaft.

[0026] The support rod 2 has an installation groove, in which a drive motor is fixedly installed. The output end of the drive motor is fixedly connected to the limit frame 5. The drive motor drives the limit frame 5 to rotate, which in turn drives the rotating arm 6 to rotate, thereby adjusting the position of the limit plate 10.

[0027] It should be noted that the specific model and specifications of the hydraulic cylinder 19 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be elaborated here.

[0028] The functional principle of this utility model can be explained through the following operation methods:

[0029] In use, by rotating the limiting frame 5, the limiting plate 10 is moved to directly above the steel coil. By extending and retracting the first hydraulic rod 7, the height of the limiting plate 10 is adjusted so that the limiting plate 10 and the steel coil are in contact. By extending and retracting the second hydraulic rod 13, the moving plate 14 is driven to slide upward in the first sliding groove 12, so that the moving plate 14 pulls one end of the transmission rod 15 upward, and the other end of the transmission rod 15 pulls the sliding block 16 to move in the direction of the limiting rod 11 in the second sliding groove 17, thereby adjusting the distance between the three bearing brackets 18 so that the bearing brackets 18 support the steel coil.

[0030] By extending and retracting the hydraulic cylinder 19, the height of the clamping plate 20 is adjusted so that the clamping plate 20 clamps the upper end of the steel coil, fixing the steel coil inside the bearing bracket 18 and preventing the steel coil from falling off the bearing bracket 18.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
