Description

Technical Field

[0001] This utility model relates to the field of vehicle processing technology, specifically to a clamping structure for a robot welding fixture. Background Technology

[0002] Vehicle machining welding fixtures are crucial process equipment in automobile manufacturing. They are mainly used to ensure the accuracy, quality, and efficiency of vehicle welding. During vehicle machining welding, fixtures play a role in positioning and clamping workpieces, ensuring that each component is in the correct position during welding, thereby ensuring the accuracy and consistency of welding. At the same time, fixtures can also effectively prevent errors caused by heat deformation or stress concentration during welding, thus improving welding quality.

[0003] Existing welding fixtures typically clamp workpieces using clamping plates. However, current technology cannot clamp and weld multiple sets of workpieces simultaneously, meaning only one set can be processed at a time. This significantly limits the throughput of the production line, leading to a decrease in overall production efficiency. Due to the low production efficiency, achieving the same output may require longer working hours and higher energy consumption, thus increasing production costs. Furthermore, existing technology can only clamp workpieces of specific sizes. When processing workpieces of different sizes, it is necessary to change the fixture or adjust the production line, which greatly reduces the flexibility and adaptability of the production line.

[0004] Therefore, it is necessary to provide a new clamping structure for a robotic welding fixture to solve the above-mentioned technical problems. Utility Model Content

The second clamping plate 17 achieves the effect of clamping larger workpieces, which is convenient for clamping workpieces of different sizes.

[0024] A drive motor 18 is mounted on the top of the support frame 2. A first gear 19 is fixedly connected to the output end of the drive motor 18. A second gear 20 is meshed with the outer side of the first gear 19. A drive rod 21 is fixedly connected to the inner ring of the second gear 20. The top of the drive rod 21 is fixedly connected to the bottom of the placement plate 5. A fixing sleeve 22 is fixedly connected to the top of the support plate 4. The inner wall of the fixing sleeve 22 is rotatably connected to the outer side of the drive rod 21. A limit rod 23 is fixedly connected to the outer side of the fixing sleeve 22. Multiple sets of limit rods 23 are fixed to the outer side of the fixing sleeve 22. The outer side of the limit rod 23 is slidably connected to the limit sleeve 24, which can limit the guide rod 7. The bottom of the guide rod 7 is fixedly connected to the top of the limit sleeve 24. One end of the limit rod 23 is fixedly connected to the limit block 25, which limits the limit sleeve 24.

[0026] Working Principle: When using this device, smaller workpieces are placed on the placement plate 5. The drive motor 18 drives the first gear 19 and the second gear 20 to rotate, which in turn drives the drive rod 21 and the placement plate 5 to rotate. This causes the guide rod 7 to slide inside the guide groove 6, moving it towards the center of the placement plate 5. This causes the limiting sleeve 24 to slide outside the limiting rod 23. The guide rod 7 drives the mounting block 8 and the first clamping plate 9 to clamp the workpiece. By setting multiple sets of placement plates 5, multiple sets of workpieces can be clamped, improving the workpiece clamping and welding efficiency. Larger workpieces are placed on the fixed plate 29. The electric push rod 12 pulls the support ring 13 downward, causing the first connecting frame 14 to move downward, which drives the connecting block 15 to rotate. The connecting block 15 pulls the second connecting frame 16 to move. The second connecting frame 16 drives the guide block 31 to slide inside the guide frame 30, causing the second clamping plate 17 to move horizontally. This allows the second clamping plate 17 to clamp larger workpieces and facilitates clamping workpieces of different sizes, improving the workpiece welding effect.
