Description

Technical Field

[0001] This utility model relates to the field of industrial robot technology, specifically to a support frame for the maintenance and repair of industrial robots. Background Technology

[0002] Industrial robots are core automated machines commonly used in modern manufacturing. They are also commonly called robotic arms, industrial manipulators, robotic arms, robot arms, robotic hands, etc. Industrial robots will experience wear and tear after a certain period of use, so they need to be maintained and repaired regularly. Due to the large overall weight of industrial robots, support frames are often needed to support and fix the disassembled and moving mechanical parts when repairing industrial robots.

[0003] According to the patent announcement number "CN219190110U" published on the China Patent Network, entitled "A Support Frame for Maintenance and Repair of Industrial Robots," the robot body includes a support base on one side of the robot body. A support column is welded to the top center of the support base, and a cylinder is installed at the top center of the support column. A support plate is fixedly connected to the top center of the cylinder. A fixed inner cavity is opened inside the support plate. A bidirectional lead screw is rotatably installed at the center of one end of the inner wall of the fixed inner cavity. A movable plate is symmetrically sleeved on one side of the outer surface of the bidirectional lead screw. Sliding grooves are opened on both sides of the top of the inner wall of the fixed inner cavity. Connecting blocks are welded inside the sliding grooves on both sides of the top of the movable plate. Limiting blocks are installed at the top of the connecting blocks extending to the upper surface of the support plate. This solution has the effect of facilitating support and limiting at a certain position of the robot body, improving the stability of the support plate when supporting the robot body, making people safer during maintenance and repair, and improving the overall practicality of the support plate.

[0004] While the aforementioned patents can improve the stability of the support, the heavy weight of the robotic arm causes a strong impact on the support plate during disassembly. This not only affects the service life of the support frame but also damages the robotic arm due to the impact. Therefore, we provide a support frame for industrial robot maintenance and repair to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a support frame for the maintenance and repair of industrial robots, to solve the problem mentioned in the background art where the disassembly of the robotic arm causes a strong impact on the support plate, which not only affects the service life of the support frame but also leads to damage to the robotic arm due to the impact force. To achieve the above objective, this utility model provides the following technical solution: a support frame for the maintenance and repair of industrial robots, including a mounting base, with casters rotatably connected to the bottom of the mounting base, a limit frame fixedly connected to the top of the mounting base, a limit groove provided inside the limit frame, a lifting mechanism provided at the top of the mounting base, and a protective mechanism provided inside the limit frame.

[0006] More preferably, the lifting mechanism includes a drive motor fixedly connected inside the mounting base, and the output end of the drive motor is fixedly connected to a drive threaded rod. The outer wall of the drive threaded rod is threadedly connected to a lifting threaded tube, and a buffer assembly is provided at the top of the lifting threaded tube.

[0007] More preferably, the buffer assembly includes a buffer base plate fixedly connected to the top of the lifting threaded tube, and a lifting limit block is fixedly connected to the side of the buffer base plate near the limit frame. The outer wall of the lifting limit block is slidably connected to the inner wall of the limit groove. Four buffer rebound rods pass through the interior of the buffer base plate and are slidably connected to the four buffer rebound rods. The four buffer rebound rods are distributed in a rectangular array about the center of the top of the buffer base plate. A bearing top plate is fixedly connected to the top of the buffer rebound rod, and a buffer spring is installed between the buffer base plate and the bearing top plate outside the buffer rebound rod.

[0008] More preferably, the protective mechanism includes a protective threaded rod that extends through one side of the bearing top plate and the protective limiting block and is rotatably connected to the bearing top plate and the protective limiting block, and a protective gear is fixedly connected to one end of the protective threaded rod.

[0009] More preferably, the protective mechanism further includes a fixed toothed plate fixedly connected to the outside of the limiting frame, and one side of the fixed toothed plate is meshed with the outside of the protective gear.

[0010] Further preferably, the protective mechanism further includes two movable threaded blocks threadedly connected to the protective threaded rod, and the two movable threaded blocks are symmetrically distributed about the center of the top of the bearing plate. A protective fixing plate is fixedly connected to the side of the movable threaded block away from the protective threaded rod, and two protective spring rods are symmetrically passed through the protective fixing plate. A protective plate is fixedly connected to one end of the protective spring rod, and a protective spring is installed between the protective fixing plate and the protective plate on the outer wall of the protective spring rod. A protective limiting plate is fixedly connected to the other end of the protective spring rod. A movable sliding groove matching the movable threaded block is provided on the top of the bearing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this invention, the drive motor is first started, and the rotation of the drive motor drives the drive threaded rod to rotate. The rotating drive threaded rod, through the thread action and the limiting action of the limiting frame, drives the lifting threaded tube to move upward. The upward movement of the lifting threaded tube drives the buffer base plate to move upward. The upward movement of the buffer base plate drives the bearing top plate to move upward through the buffer rebound rod, so that the bearing plate can rise to the bottom of the robot arm. The rectangular array buffer system formed by four sets of spring buffer rebound rods can effectively absorb the impact force when the robot arm is disassembled, and avoid direct impact on the bearing top plate, which would cause damage to the robot arm.

[0013] In this invention, the impact force during the disassembly of the robotic arm can be absorbed while limiting the disassembled robotic arm, preventing the relatively rounded robotic arm from slipping off the top of the supporting plate during the disassembly process. This not only prevents damage to the robotic arm but also improves the safety of workers during robot maintenance and repair. Attached Figure Description

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a support frame for the maintenance and repair of industrial robots, including a mounting base 1, a movable wheel 2 rotatably connected to the bottom of the mounting base 1, a limit frame 3 fixedly connected to the top of the mounting base 1, a limit groove 4 provided inside the limit frame 3, a lifting mechanism provided at the top of the mounting base 1, and a protective mechanism provided inside the limit frame 3.

[0022] In this embodiment, as Figures 1 to 3 As shown, the lifting mechanism includes a drive motor 5 fixedly connected inside the mounting base 1, and a drive threaded rod 6 fixedly connected to the output end of the drive motor 5. A lifting threaded tube 7 is threadedly connected to the outer wall of the drive threaded rod 6, and a buffer assembly is provided at the top of the lifting threaded tube 7. The buffer assembly includes a buffer base plate 8 fixedly connected to the top of the lifting threaded tube 7, and a lifting limit block 9 is fixedly connected to the side of the buffer base plate 8 near the limit frame 3. The outer wall of the lifting limit block 9 is slidably connected to the inner wall of the limit groove 4. Four buffer rebound rods 10 pass through the interior of the buffer base plate 8 and are slidably connected to the four buffer rebound rods 10. The four buffer rebound rods 10 are arranged in a rectangular array about the center of the top of the buffer base plate 8. A bearing top plate 12 is fixedly connected to the top of the buffer rebound rods 10, and a buffer spring 11 is installed between the buffer base plate 8 and the bearing top plate 12 outside the buffer rebound rods 10.

[0023] In this embodiment: the drive motor 5 is started, and the drive motor 5 rotates, which drives the drive threaded rod 6 to rotate. The rotating drive threaded rod 6 drives the lifting threaded tube 9 to move upward through the thread action and the limiting action of the limiting frame 3. The upward movement of the lifting threaded tube 9 drives the buffer base plate 8 to move upward. The upward movement of the buffer base plate 8 drives the bearing top plate 12 to move upward through the buffer rebound rod 10, so that the bearing plate 12 can rise to the bottom of the robot arm. The buffer spring 11 can buffer the impact force of the robot arm falling on the bearing top plate 12 during disassembly and maintenance, and avoid direct impact on the bearing top plate 12, which would cause damage to the robot arm.

[0024] In this embodiment, as Figures 3 to 5 As shown, the protective mechanism includes a protective threaded rod 16 that extends through one side of the bearing top plate 12 and the protective limiting block 13 and is rotatably connected to the bearing top plate 12 and the protective limiting block 13. One end of the protective threaded rod 16 is fixedly connected to a protective gear 14. The protective mechanism also includes a fixed toothed plate 15 fixedly connected to the outside of the limiting frame 3, with one side of the fixed toothed plate 15 meshing with the outside of the protective gear 14. The protective mechanism also includes two movable threaded blocks 17 threadedly connected to the protective threaded rod 16, and the two movable threaded blocks 17 are positioned relative to the bearing top plate 12. The top center is symmetrically distributed. A protective fixing plate 18 is fixedly connected to the side of the movable threaded block 17 away from the protective threaded rod 16. Two protective rebound rods 19 are symmetrically passed through the protective fixing plate 18. A protective plate 20 is fixedly connected to one end of the protective rebound rod 19. A protective spring 21 is installed between the protective fixing plate 18 and the protective plate 20 on the outer wall of the protective rebound rod 19. A protective limiting plate 22 is fixedly connected to the other end of the protective rebound rod 19. A movable sliding groove matching the movable threaded block 17 is provided on the top of the bearing top plate 12.

[0025] In this embodiment: during the upward movement of the supporting top plate 12, the protective threaded rod 16 is driven to move upward, thereby driving the protective gear 14 to move upward. The protective gear 14 rotates through meshing with the fixed toothed plate 15, thereby driving the protective threaded rod 16 to rotate. Then, through the thread action with the movable threaded block 17, the movable threaded block 17 moves linearly relative to the other side. The linearly moving movable threaded block 17 drives the protective spring rod 19 to move linearly through the protective fixed plate 18. The linearly moving protective spring rod 19 drives the protective plate 20 to move linearly. The linearly moving protective plate 20 can limit the disassembled robotic arm, preventing the relatively rounded robotic arm from slipping off the top of the supporting top plate 12 during disassembly. This prevents damage to the robotic arm and improves the safety of the staff during robot maintenance and repair.

[0026] The method of use and advantages of this utility model: The working process of this support frame for industrial robot maintenance and repair is as follows:

[0027] like Figures 1 to 5 As shown, firstly, the drive motor 5 is started. The rotation of the drive motor 5 drives the drive threaded rod 6 to rotate. The rotating drive threaded rod 6, through the thread action and the limiting action of the limit frame 3, drives the lifting threaded tube 9 to move upward. The upward movement of the lifting threaded tube 9 drives the buffer base plate 8 to move upward. The upward movement of the buffer base plate 8 drives the bearing top plate 12 to move upward through the buffer rebound rod 10, so that the bearing plate 12 can rise to the bottom of the robot arm. The buffer spring 11 can buffer the impact force of the robot arm falling on the bearing top plate 12 during disassembly and maintenance, avoiding direct impact on the bearing top plate 12 and damage to the robot arm. During the upward movement of the bearing top plate 12, the drive protective threaded rod 16 moves upward, thereby driving the protective teeth. As wheel 14 moves upward, protective gear 14 rotates through meshing with fixed tooth plate 15, thereby rotating protective threaded rod 16. This, in turn, rotates through the threaded action with movable threaded block 17, causing movable threaded block 17 to move linearly relative to it. The linearly moving movable threaded block 17, via protective fixed plate 18, drives protective spring rod 19 to move linearly. The linearly moving protective spring rod 19 then drives protective plate 20 to move linearly. The linearly moving protective plate 20 can limit the disassembled robotic arm, preventing the relatively rounded robotic arm from slipping off the top of the supporting top plate 12 during disassembly. This prevents damage to the robotic arm and improves the safety of personnel during robot maintenance and repair.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
