Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and in particular to a welding robot that is easy to maintain. Background Technology

[0002] With the rapid development of industrial automation technology, welding robots are widely used in automobile manufacturing, machining and other fields due to their high efficiency and precision. Their core functionality requires a stable, fixed structure to ensure positional accuracy during operation, while also meeting the needs for regular maintenance and component replacement during long-term use. Therefore, the ease and stability of fixing and disassembling these robots are key factors affecting their efficiency.

[0003] Existing welding robots mostly use complex bolt groups or clip structures to fix the robot body. Disassembly and assembly require special tools to operate one by one, which is not only time-consuming and labor-intensive, resulting in low maintenance efficiency, but also prone to problems such as stripped bolts and loose clips after long-term disassembly and assembly. This makes it difficult to ensure the stability of the robot body after installation and affects the accuracy of welding operations. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies and provide a welding robot that is easy to maintain.

[0005] Therefore, this utility model provides a welding robot that is easy to maintain, including a workbench. The lower surface of the workbench has a mounting groove, and a mounting plate is disposed inside the mounting groove. A worm gear is rotatably mounted on the upper surface of the mounting plate. Four inclined grooves are formed on the upper surface of the worm gear. A sliding column is slidably mounted on the inner wall of each inclined groove. An extrusion block is fixedly connected to the upper surface of each sliding column. A positioning groove is formed on the upper surface of the workbench, and a positioning block is disposed inside the positioning groove. A robot component is fixedly connected to the upper surface of the positioning block. Four extrusion grooves are formed on the side wall of the positioning block, and the inclined surface of the extrusion block fits into the inclined surface of the extrusion groove. A rotating groove is formed inside the workbench, and a worm is rotatably mounted on the inner wall of the rotating groove. The worm meshes with the worm gear, and a handle is fixedly connected to the end of the worm furthest from the worm gear.

[0006] Preferably, the upper surface of the mounting groove is provided with four sliding grooves, the sliding column is located inside the sliding groove, the upper surface of the sliding groove is provided with a moving groove, and the pressing block is located inside the moving groove.

[0007] Preferably, the inner wall of the moving groove has two first limiting grooves, and the side wall of the extrusion block is fixedly connected to two limiting blocks, the limiting blocks being located inside the first limiting grooves.

[0008] Preferably, the bottom of the positioning groove is provided with a magnetic suction groove, and a magnetic suction cup is fixedly connected to the bottom of the magnetic suction groove. The positioning block and the worktable are magnetically connected through the magnetic suction cup.

[0009] Preferably, the inner wall of the positioning groove is provided with four second limiting grooves, and the side wall of the positioning block is fixedly connected with four limiting pins, the limiting pins being located inside the second limiting grooves.

[0010] Preferably, four positioning members are fixedly connected to the lower surface of the mounting plate, and the positioning members are fixedly connected to the worktable by bolts.

[0011] Preferably, four mounting plates are fixedly connected to the side wall of the workbench, and bolt holes are provided on the upper surface of the mounting plates.

[0012] This utility model provides a welding robot that is easy to maintain, and has the following beneficial effects:

[0013] Compared to existing technologies, this easy-to-maintain welding robot comprises a throttle, worm gear, worm wheel, sliding column, inclined groove, extrusion block, positioning block, positioning groove, extrusion groove, and robot components. Rotating the throttle engages the worm gear with the worm wheel, causing the sliding column to slide along the inclined groove and push the extrusion blocks away from each other, thus placing the positioning block into the positioning groove. Reversing the throttle causes the four extrusion blocks to move closer together. As the worm continues to rotate, the inclined surface of the extrusion block continuously presses against the inclined surface of the extrusion groove, subjecting the positioning block to continuous downward pressure, resulting in a more stable installation of the positioning block. This makes the robot components more securely installed, and the fixing can be released by simply turning the handle in the opposite direction. Compared with existing welding robots that mostly use complex bolt groups or buckle structures to fix the robot body, which require special tools to operate one by one during disassembly and assembly, this is not only time-consuming and labor-intensive, resulting in low maintenance efficiency, but also prone to problems such as stripped bolts and loose buckles after long-term disassembly and assembly, making it difficult to ensure the stability of the robot body after installation and affecting the accuracy of welding operations. This easy-to-maintain welding robot can quickly disassemble and assemble robot components by simply turning the handle, and the robot components are installed securely during the disassembly and assembly process.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Depend on Figures 1-6As shown, this utility model provides a welding robot that is easy to maintain, including a workbench 1. The lower surface of the workbench 1 has a mounting groove 2, and a mounting plate 3 is disposed inside the mounting groove 2. A worm gear 4 is rotatably mounted on the upper surface of the mounting plate 3. Four inclined grooves 5 are formed on the upper surface of the worm gear 4. Sliding columns 6 are slidably mounted on the inner wall of the inclined grooves 5. A pressing block 7 is fixedly connected to the upper surface of the sliding column 6. A positioning groove 8 is formed on the upper surface of the workbench 1, and a positioning block 9 is disposed inside the positioning groove 8. A machine tool is fixedly connected to the upper surface of the positioning block 9. The human component 14 has four extrusion grooves 10 on its side wall for positioning block 9. The inclined surface of extrusion block 7 fits into the inclined surface of extrusion groove 10. The worktable 1 has a rotating groove 11 inside. A worm gear 12 is rotatably mounted on the inner wall of the rotating groove 11. The worm gear 12 meshes with the worm wheel 4. A handle 13 is fixedly connected to the end of the worm gear 12 away from the worm wheel 4. By rotating the handle 13, the worm gear 12 is driven to mesh with the worm wheel 4, causing the sliding column 6 to slide along the inclined groove 5 and push the extrusion blocks 7 away from each other, thereby placing the positioning block 9 into the positioning groove 8. Then, rotating the handle 13 in the reverse direction causes the four extrusion blocks 7 to move closer to each other. As the worm gear 12 continues to rotate, the inclined surface of the extrusion block 7 continuously presses against the inclined surface of the extrusion groove 10, causing the positioning block 9 to be subjected to continuous downward pressure, making the positioning block 9 more securely installed, and thus making the robot component 14 more securely installed. Rotating the handle 13 in the reverse direction can release the fixation, realizing the quick assembly and disassembly of the robot component 14 and improving maintenance convenience. At the same time, the worm gear 4 and the worm gear 12 transmission have self-locking properties, which can ensure the stability of the positioning block 9 after it is fixed and prevent the robot component 14 from shifting during operation. The upper surface of the mounting groove 2 has four sliding grooves 15, the sliding column 6 is located inside the sliding groove 15, and the upper surface of the sliding groove 15 has a moving groove 16. The extrusion block 7 is located inside the moving groove 16. The sliding groove 15 provides a directional sliding trajectory for the sliding column 6, preventing the sliding column 6 from deviating from the preset path during the sliding process. The moving groove 16 provides sufficient space for the horizontal movement of the extrusion block 7, ensuring that the extrusion block 7 can smoothly fit or separate from the extrusion groove 10, ensuring the smoothness of the fixing and disassembly actions.

[0023] Depend on Figures 1-6As shown, this utility model provides a welding robot that is easy to maintain. The inner wall of the moving groove 16 has two first limiting grooves 17. Two limiting blocks 18 are fixedly connected to the side wall of the extrusion block 7. The limiting blocks 18 are located inside the first limiting grooves 17. The limiting blocks 18 cooperate with the first limiting grooves 17 to limit the movement stroke of the extrusion block 7, preventing it from detaching from the moving groove 16 due to excessive movement. Simultaneously, it prevents the extrusion block 7 from rotating during movement, ensuring that the inclined surface of the extrusion block 7 always accurately fits the inclined surface of the extrusion groove 10, improving the reliability of the structure. A magnetic suction groove 24 is provided at the inner bottom of the positioning groove 8. A magnetic suction cup 25 is fixedly connected to the inner bottom of the magnetic suction groove 24. The positioning block 9 and the worktable 1 are magnetically connected via the magnetic suction cup 25. The magnetic chuck 25 pre-fixes the positioning block 9, facilitating quick alignment of the positioning block 9 with the installation position of the positioning groove 8 during installation, reducing alignment and adjustment time. Simultaneously, the magnetic attraction enhances the connection stability between the positioning block 9 and the worktable 1, assisting the pressing block 7 in improving the fixing effect. Four second limiting grooves 26 are provided on the inner wall of the positioning groove 8, and four limiting pins 19 are fixedly connected to the side wall of the positioning block 9. The limiting pins 19 are located inside the second limiting grooves 26, and their cooperation with the second limiting grooves 26 provides a certain guiding ability for the positioning block 9 when placed in the positioning groove 8, preventing the welding position from shifting due to the rotation of the positioning block 9 during robot component 14 operation. It also assists in the rapid positioning of the positioning block 9, further improving installation efficiency.

[0024] Depend on Figures 1-6 As shown, this utility model provides a welding robot that is easy to maintain. Four positioning components 20 are fixedly connected to the lower surface of the mounting plate 3. The positioning components 20 are fixedly connected to the worktable 1 by bolts 21. The positioning components 20 and bolts 21 cooperate to firmly fix the mounting plate 3 in the mounting groove 2, ensuring the stability of components such as the worm gear disk 4 and sliding column 6 during operation. Simultaneously, the bolt 21 connection facilitates disassembly, allowing for quick removal for maintenance or replacement when the mounting plate 3 or its upper components malfunction. Four mounting plates 22 are fixedly connected to the side wall of the worktable 1. Bolt holes 23 are provided on the upper surface of the mounting plates 22. The mounting plates 22 cooperate with the bolt holes 23, facilitating the fixing of the worktable 1 to a preset position in the work area using bolts, preventing the worktable 1 from shifting during robot component 14 operation. This design also adapts to the installation requirements of different sites, improving the flexibility and stability of equipment installation.
