Technical Field

[0001] This utility model relates to the field of robotic welding technology, specifically a positioner for robotic welding. Background Technology

[0002] In modern manufacturing, welding technology is one of the most important processes for joining metal parts. With the rapid development of industrial automation, robotic welding technology, due to its high efficiency, high precision, and strong consistency, is widely used in automobile manufacturing, aerospace, heavy machinery, and other fields. In the robotic welding process, the positioner, as a key auxiliary device, can realize multi-angle and multi-position adjustment of the workpiece, ensuring the smooth progress of the welding process.

[0003] However, existing positioners have certain limitations when repairing and replacing welding stations. When it is necessary to repair or replace the welding station or platform, manual disassembly and transportation are usually required, which not only increases the difficulty of operation, but may also lead to equipment damage or personnel injury.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A positioner for robotic welding, including

[0007] A base, on the top left side of which a frame is fixedly installed, and an adjustment mechanism is provided at the upper end of the frame;

[0008] A movable frame is movably mounted on the top right side of the base, and a translation mechanism is provided between the movable frames of the base;

[0012] Preferably, the translation mechanism includes a second lead screw, which is movably installed at the middle of the right side of the top of the base. The middle of the bottom of the movable frame is threadedly connected to the second lead screw. Guide rails are fixedly installed on both sides of the top right side of the base. The bottom of the movable frame is movably connected to the guide rails. A motor is fixedly installed at the middle of the right side of the base.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A positioner for robotic welding includes a base 1. A frame 2 is fixedly mounted on the top left side of the base 1. An adjustment mechanism is provided on the upper end of the frame 2. The adjustment mechanism includes a tilting frame 5. Tilting frames 5 are movably mounted on the inner side of the upper end of the frame 2. A reducer 6 is fixedly mounted on the upper right side of the tilting frame 5. A motor 7 is fixedly mounted on the lower external side of the reducer 6. The output shaft of the motor 7 is fixedly connected to the high-speed shaft of the reducer 6. The right tilting frame 5 is fixedly connected to the low-speed shaft of the reducer 6. The left tilting frame 5 is movably connected to the upper left side of the frame 2 via a rotating shaft. The adjustment mechanism also includes... Platform 8 is detachably installed between the bottom ends of the two tilting frames 5. A motor 9 is fixedly installed at the bottom middle of platform 8. The output shaft of motor 9 passes through platform 8 and is fixedly connected to welding table 10. An annular groove 11 is opened in the middle of platform 8. Four support rods 12 are fixedly installed at the bottom of welding table 10 with equal arc. The bottom end of support rod 12 is sleeved with bearing 13 that is movably connected to annular groove 11. Threaded grooves 19 are opened on both sides of the bottom end of tilting frame 5. Bolts 20 are movably installed on both sides of the bottom end of platform 8. The end of bolt 20 passes through platform 8 and is threadedly connected to threaded groove 19.

[0026] In this embodiment, by setting up a structure connecting the flipping frame 5, the platform 8, and the bolts 20, the welding table 10 can be quickly flipped and disassembled. When the welding table 10 or the platform 8 needs to be repaired, simply start the motor 37 to drive the flipping frame 5 to rotate so that the welding table 10 faces down, and then remove the bolts 20 to complete the separation. The disassembled platform 8 and welding table 10 can be smoothly moved out of the work area by the roller conveyor 4 without manual handling, which simplifies the maintenance process, reduces the difficulty of operation, and significantly improves maintenance efficiency and operational safety.

[0027] like Figure 1 As shown, a movable frame 3 is movably installed on the top right side of the base 1. A translation mechanism is provided between the base 1 and the movable frame 3. The translation mechanism includes a second lead screw 14. The second lead screw 14 is movably installed in the middle of the top right side of the base 1. The bottom middle of the movable frame 3 is threadedly connected to the second lead screw 14. Guide rails 15 are fixedly installed on both sides of the top right side of the base 1. The bottom of the movable frame 3 is movably connected to the guide rails 15. A motor 21 is fixedly installed in the middle of the right side of the base 1. The motor 21 is fixedly connected to the second lead screw 14. A roller conveyor 4 is movably installed on the front of the movable frame 3. A lifting mechanism is provided between the movable frame 3 and the roller conveyor 4. The lifting mechanism includes a lead screw 16. The lead screw 16 is movably installed in the middle of the movable frame 3. A motor 17 is fixedly installed at the top of the middle of the movable frame 3. The output shaft of the motor 17 is fixedly connected to the lead screw 16. The middle right side of the roller conveyor 4 is threadedly connected to the lead screw 16. Guide rails 18 are fixedly installed at both ends of the front of the movable frame 3. The two ends of the right side of the roller conveyor 4 are slidably connected to the guide rails 18.

[0028] In this embodiment, by integrating the roller conveyor 4 and the lifting mechanism, the workpiece can be transported smoothly and positioned accurately. For excessively heavy workpieces, the operator only needs to place them on the roller conveyor 4. Through the rotation of the rollers and the vertical movement of the lifting mechanism, the workpiece can be easily lifted to a height aligned with the welding table 10. This avoids the tedious operation of manually carrying heavy objects in the traditional feeding process, significantly reducing labor intensity and improving feeding efficiency and operational safety.

[0029] Working principle: First, the workpiece is placed on the roller conveyor 4, which smoothly transports the workpiece to the designated position through the rotation of its rollers. Next, the lifting mechanism is activated, and motor 17 drives screw 16 to rotate, causing the roller conveyor 4 to move vertically along guide rail 18, lifting the workpiece to a height aligned with the welding table 10. Then, the translation mechanism starts working, and motor 21 drives screw 14 to rotate, causing the movable frame 3 to move horizontally along guide rail 15, translating the workpiece from above the roller conveyor 4 to directly above the welding table 10. If further adjustments are needed... When platform 8 or welding table 10 is being repaired, start motor 3 7. Motor 3 7 reduces speed through reducer 6 and drives the tilting frame 5 to rotate. The tilting frame 5 drives platform 8 to tilt so that welding table 10 faces down. Then remove bolt 20 to separate tilting frame 5 from platform 8. Then control movable frame 3 to move roller conveyor 4 to below welding table 10 and adjust the height of roller conveyor 4. Use roller conveyor 4 to lift the disassembled platform 8 and welding table 10. Then control roller conveyor 4 to descend and drive movable frame 3 to return to the initial point.
