Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a multifunctional robotic arm for mechanical design and manufacturing. Background Technology

[0002] Mechanical design and manufacturing is a comprehensive field encompassing a series of complex and critical processes, from product design concepts and drawing to parts processing and product assembly. Its aim is to create mechanical equipment and products that meet various functional requirements and possess specific performance and quality standards. Robotic arms used in mechanical design and manufacturing are extremely important automated equipment in this field. Based on preset programs and precise control commands, they can accurately and flexibly complete diverse tasks such as parts gripping, handling, assembly, and inspection, effectively improving production efficiency, processing accuracy, and automation levels in the mechanical manufacturing process, and greatly promoting the continuous advancement of mechanical design and manufacturing towards intelligence and high efficiency.

[0003] Traditional robotic arms in mechanical design and manufacturing typically consist of a robotic arm, joint actuators, end effectors, and a control system. The robotic arm generally has multiple joints and is mostly constructed of metal to ensure sufficient strength and stability; its shape and size are designed according to the specific application. The joint actuators are often a combination of a motor and a reducer. The motor provides power, and the reducer adjusts the output torque and speed to control the joint rotation. End effectors come in various types, commonly including grippers for grasping workpieces and suction cups for adsorbing specific objects.

[0004] Traditional multi-functional robotic arms used in mechanical design and manufacturing often have limitations in their lifting structures, resulting in insufficient verticality during lifting. For example, some robotic arms use a single guide rail or a simple guide rod to guide the lifting motion. This structure makes it difficult to ensure that the precise vertical orientation is maintained throughout the entire lifting stroke. Due to manufacturing precision errors and wear after prolonged use, gaps will form between the guide rail and the slider, and between the guide rod and the sleeve, making the lifting components prone to lateral deviation or tilting during operation. This lack of verticality has many adverse effects. In precision assembly tasks, it leads to inaccurate alignment of parts, affecting the assembly quality and performance of the product. In machining operations, it causes deviations in the relative positions of the tool and the workpiece, resulting in decreased machining accuracy and increased scrap rate. Moreover, non-vertical lifting motion will additionally increase uneven stress on the mechanical structure, accelerate component wear and fatigue, reduce the service life of the robotic arm, increase maintenance costs and equipment failure risks, and ultimately affect the efficiency and effectiveness of the entire mechanical manufacturing production process. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-functional robotic arm for mechanical design and manufacturing, aiming to improve the problem that the lifting structure of traditional multi-functional robotic arms for mechanical design and manufacturing often has limitations that affect the efficiency and effectiveness of the entire mechanical manufacturing production process.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multifunctional robotic arm for mechanical design and manufacturing, comprising a robotic arm, a connecting platform fixedly connected to the side wall of the robotic arm, a lifting assembly provided on the side wall of the connecting platform, and a disassembly assembly provided at the bottom of the connecting platform;

[0007] The lifting assembly includes a motor, which is fixedly connected to the side wall of the connecting platform. A transmission wheel is fixedly connected to the output end of the motor. The transmission wheel is vertically rotatably connected to the inside of the connecting platform. A synchronous belt is slidably connected to the outer wall of the transmission wheel. A connecting member is fixedly connected to the outer wall of the synchronous belt. A support platform is fixedly connected to the side wall of the connecting member. A fixing column is fixedly connected to the bottom of the support platform. A gripper is provided at the bottom end of the fixing column. A fixing platform is fixedly connected to the bottom end of the fixing column.

[0008] Furthermore, the disassembly assembly includes a throttle handle that is rotatably connected inside the fixed platform.

[0009] Furthermore, a worm gear is fixedly connected to one end of the throttle, and the worm gear is rotatably connected inside the fixed platform.

[0010] Furthermore, a connecting column is fixedly connected inside the fixed platform, and a worm gear is rotatably connected to the outer wall of the connecting column.

[0011] Furthermore, the worm gear meshes with the worm, and a chassis is fixedly connected to the bottom of the worm gear.

[0012] Furthermore, the chassis sidewall is rotatably connected to a plurality of connecting rods, and one end of each connecting rod is rotatably connected to a connecting rod.

[0013] Furthermore, a push block is rotatably connected to one end of the connecting rod, and a locking platform is slidably connected to the bottom of the push block.

[0014] Furthermore, the clamping platform is fixedly connected to the top of the gripper, and a spring is provided on the side wall of the push block. One end of the spring is fixedly connected to the inside of the fixing platform, and the other end of the spring is fixedly connected to the side wall of the push block.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor first outputs rotational power to the transmission wheel. During the rotation of the transmission wheel, the connecting parts on its outer wall slide. Finally, the displacement of the connecting parts further drives the support platform on its side wall to move. The support platform then drives the fixed column at its bottom to push and pull the fixed platform, so that the bottom of the fixed platform can be raised and lowered with a high degree of verticality. This effectively reduces processing errors and enables the product's dimensional accuracy, shape accuracy, surface roughness, and other quality indicators to reach higher standards.

[0017] 2. In this utility model, the throttle rotates inside the fixed platform after being subjected to force, driving the worm gear at one end to rotate synchronously. Finally, the push blocks on both sides slide synchronously, thus releasing the locking mechanism and allowing the locking mechanism to be removed for replacement. The tension of the spring ensures that the locking mechanism will not slip out when the push blocks are inside the fixed platform. Attached Figure Description

[0023] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-2The present invention provides an embodiment of a multifunctional robotic arm for mechanical design and manufacturing, comprising a robotic arm 1, a connecting platform 2 fixedly connected to the side wall of the robotic arm 1, a lifting component provided on the side wall of the connecting platform 2, and a disassembly component provided at the bottom of the connecting platform 2.

[0025] The lifting assembly includes a motor 3, which is fixedly connected to the side wall of the connecting platform 2. A transmission wheel 4 is fixedly connected to the output end of the motor 3. The transmission wheel 4 is vertically rotatable inside the connecting platform 2. A synchronous belt 5 is slidably connected to the outer wall of the transmission wheel 4. A connector 6 is fixedly connected to the outer wall of the synchronous belt 5. A support platform 7 is fixedly connected to the side wall of the connector 6. A fixing column 8 is fixedly connected to the bottom of the support platform 7. A gripper 20 is provided at the bottom end of the fixing column 8. A fixing platform 9 is fixedly connected to the bottom end of the fixing column 8.

[0026] Specifically, when motor 3 is started, it first outputs rotational power to transmission wheel 4, causing transmission wheel 4 to rotate inside connecting platform 2. During the rotation of transmission wheel 4, the connecting piece 6 connected to its outer wall slides on a specific track or guide structure. At the same time, due to the linkage of the mechanical structure, another transmission wheel 4 also rotates synchronously inside connecting platform 2. As transmission wheel 4 rotates, the position of connecting piece 6 changes vertically during the sliding process. When connecting piece 6 is displaced, it further drives the support platform 7 on its side wall to move along with it. The support platform 7 then drives the fixed column at its bottom. 8. Pushing and pulling motions are performed on the fixed platform 9. Through this series of force transmissions and the coordinated action of mechanical movements, the relevant components at the bottom of the fixed platform 9 can perform vertical lifting movements with a high degree of precision. This high-precision lifting control is of great significance for the operation of the robotic arm. It can effectively reduce errors caused by inaccurate lifting during processing. Whether it is the dimensional accuracy of the product, such as the processing accuracy of length, width, and height, or the shape accuracy, such as the processing accuracy of round and square shapes, or the surface roughness, higher standards can be achieved due to the improved lifting precision. In this way, the overall quality of the product can be improved. (Refer to...) Figure 3The disassembly assembly includes a throttle 10, which is rotatably connected to the inside of a fixed platform 9. One end of the throttle 10 is fixedly connected to a worm gear 11, which is rotatably connected to the inside of the fixed platform 9. A connecting post 12 is fixedly connected inside the fixed platform 9. A worm wheel 13 is rotatably connected to the outer wall of the connecting post 12. The worm wheel 13 meshes with the worm gear 11. A chassis 14 is fixedly connected to the bottom of the worm wheel 13. Multiple connecting rods 15 are rotatably connected to the side wall of the chassis 14. One end of each connecting rod 15 is rotatably connected to a connecting rod 16. One end of each connecting rod 16 is rotatably connected to a push block 17. A locking platform 19 is slidably connected to the bottom of the push block 17. The locking platform 19 is fixedly connected to the top of a gripper 20. A spring 18 is provided on the side wall of the push block 17. One end of the spring 18 is fixedly connected to the inside of the fixed platform 9, and the other end of the spring 18 is fixedly connected to the side wall of the push block 17.

[0027] Specifically, when it is necessary to replace the gripper 20 of a specific component to adapt to the clamping requirements of different workpieces, firstly, rotate the handle 10. Under the action of external force, the handle 10 begins to rotate inside the fixed platform 9, and drives the worm 11 connected to one end to rotate together. Since there is a meshing relationship between the worm 11 and the worm wheel 13, the rotation of the worm 11 will cause the worm wheel 13 to rotate on the outer wall of the connecting column 12 inside the fixed platform 9. During the rotation of the worm wheel 13, the base 14 at its bottom will rotate synchronously. The rotation of the base 14 will drive the connecting rod 15 on its side wall to start rotating, and gradually change its tilt angle during the rotation. The movement of the connecting rod 15 will cause the connecting rod 16 to rotate and change its tilt angle as well. Then, the connecting rod 16 will push the push block 17. When the push blocks 17 on both sides slide synchronously, the clamping state of the clamping table 19 can be released. In this way, the clamping table 19 can be easily removed, so that the component gripper 20 can be replaced. At the same time, with the help of the tension of the spring 18, when the push block 17 is inside the fixed table 9, it can be ensured that the clamping table 19 will not easily slip off, ensuring the stability and reliability of the structure during normal use. It avoids the clamping table 19 from loosening or falling off due to unexpected situations, which would affect the normal operation of the equipment. It improves the flexibility and adaptability of the equipment when clamping different workpieces, and is conducive to the rapid adjustment of the clamping components according to different production tasks and workpiece requirements, improving the overall production efficiency, reducing the waste of time and labor costs caused by inconvenient equipment adjustment, and ensuring the continuity and efficiency of the production process.

[0028] Working principle: When the robotic arm needs to be raised or lowered, motor 3 is started. Motor 3 first outputs rotational power to transmission wheel 4. During the rotation of transmission wheel 4, the connecting part 6 on its outer wall slides, and at the same time, it drives another transmission wheel 4 to rotate inside the connecting platform 2. During the sliding process, the connecting part 6 on its outer wall can be raised or lowered vertically. The displacement of the connecting part 6 further drives the support platform 7 on its side wall to move accordingly. The support platform 7 then drives the fixed column 8 at its bottom to push and pull the fixed platform 9, so that the gripper 20 at the bottom of the fixed platform 9 can be raised or lowered with a high degree of verticality. This effectively reduces processing errors and enables the product's dimensional accuracy, shape accuracy, surface roughness, and other quality indicators to reach higher standards. When it is necessary to replace the gripper 20 to meet the clamping requirements of different workpieces, the rotation... The throttle 10 rotates inside the fixed platform 9 after being subjected to force, which drives the worm gear 11 at one end to rotate synchronously. Through the meshing relationship between the worm gear 11 and the worm wheel 13, the worm wheel 13 rotates on the outer wall of the connecting column 12 inside the fixed platform 9. During the rotation of the worm wheel 13, the base 14 at its bottom rotates synchronously. The rotation of the base 14 drives the connecting rod 15 on its side wall to rotate and change its tilt angle. The connecting rod 15 then causes the connecting rod 16 to rotate and change its tilt angle. The connecting rod 16 then pushes the push block 17. The push blocks 17 on both sides slide synchronously to release the locking table 19, so that the locking table 19 can be removed for the replacement of the gripper 20. The tension of the spring 18 ensures that the locking table 19 will not slip when the push block 17 is inside the fixed platform 9.
