DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings:

[0024] like Figure 1-6As shown, this embodiment provides a welding robot for metal processing that can be adjusted at multiple angles.

[0025] The welding process comprises a welding table 1 and a workpiece 2. The workpiece 2 is arranged on the top of the welding process table 1. A side mounting plate 3 is fixed to the top of the welding process table 1 by bolts. A circular hole is arranged on the side mounting plate 3. A rotating ring 4 is rotatably mounted on the inner side wall of the circular hole. A translation telescopic rod 5 is fixedly connected to the outer side wall of the rotating ring 4. The translation telescopic rod 5 can drive the U-shaped bracket 6 to translate, so that the welding gun 10 can translate. A U-shaped bracket 6 is fixedly mounted on one end of the translation telescopic rod 5. A rotating seat 7 is rotatably mounted on the U-shaped bracket 6. A U-shaped connecting plate 8 is fixedly connected to the outer side wall of the rotating seat 7. A pushing telescopic rod 9 is connected to the inner side wall of the bottom of the U-shaped connecting plate 8. A welding gun 10 is connected to one end of the pushing telescopic rod 9. Pushing the telescopic rod 9 can drive the welding gun 10 to rise and fall. Distance measuring components for measuring the workpiece 2 are arranged on the outer side walls on both sides of the U-shaped connecting plate 8. There are two workpieces 2 on the top of the welding process table 1, and their heights are different.

[0026] A circular gear ring 11 is fixedly mounted on the inner wall of the rotating ring 4, a motor connection seat 12 is fixedly mounted on the outer wall of the side mounting plate 3, a driving motor 13 is fixedly mounted on the outer wall of the motor connection seat 12, a driving gear 14 is fixedly mounted on the output shaft of the driving motor 13, and the driving gear 14 is meshed with the circular gear ring 11. The circular gear ring 11 and the rotating ring 4 can be rotated by the driving of the driving motor 13, so that the parts connected to the rotating ring 4 can be rotated. A rotating motor 15 is fixedly mounted on the outer wall of the U-shaped bracket 6, and the output shaft of the rotating motor 15 is connected to the rotating seat 7. After the rotating motor 15 is working, it can drive the rotating seat 7 and the welding gun 10 to rotate.

[0027] The distance measuring component includes a circular outer frame 16, which is fixedly connected to the outer side walls on both sides of the U-shaped connecting plate 8, and a bidirectional screw rod 17 is rotatably connected to the inner side wall of the circular outer frame 16. A clamping motor 18 is fixed to the outer side of the circular outer frame 16, and the output shaft of the clamping motor 18 is connected to one end of the bidirectional screw rod 17. Both ends of the bidirectional screw rod 17 are threadedly connected with a translation clamping block 19, and a limiting hole is arranged on the translation clamping block 19. A limiting rod 20 is fixedly installed on the inner side wall of the circular outer frame 16, and one end of the limiting rod 20 is inserted into the limiting hole. A laser rangefinder 21 is arranged at one end of the translation clamping block 19, and the laser rangefinder 21 is arranged on the top of the workpiece 2. The outer side walls on both sides of the laser rangefinder 21 are connected with fixed The positioning block 22 and the top of the circular outer frame 16 are provided with a positioning notch 23, and the positioning block 22 is arranged in the positioning notch 23. When installing the laser rangefinder 21 on the circular outer frame 16, the user can first place one end of the laser rangefinder 21 into the circular outer frame 16, and make the positioning block 22 in the positioning notch 23, and then the user can make the clamping motor 18 work to drive the bidirectional screw rod 17 to rotate, thereby driving the two translation clamping blocks 19 to approach, and then the two translation clamping blocks 19 can position the laser rangefinder 21, and the installation is convenient and quick. After the laser rangefinder 21 is installed, the user needs to adjust it to ensure that the two laser rangefinders 21 are in the same horizontal position, so as to avoid errors in the subsequent detection of the workpiece 2.

[0028] When the utility model is used, when welding two workpieces 2 on the top of the welding workbench, the user first needs to position the two workpieces 2 through the external positioning device, and then the user can make the laser rangefinders 21 on both sides of the U-shaped connecting plate 8 work. After the laser rangefinders 21 work, they can detect the distance between the workpieces 2. When the data detected by the two laser rangefinders 21 are the same, it means that the two workpieces 2 are in a horizontal state. If the two workpieces 2 are not in a horizontal state, the position needs to be adjusted. When the two workpieces 2 are in a horizontal state, the user can push the telescopic rod 9 to drive the welding gun 10 to descend. When the welding gun 10 is away from the two workpieces, the user can push the telescopic rod 9 to drive the welding gun 10 to descend. When the workpieces 2 are held at a certain distance, the welding gun 10 welds the two workpieces 2 after it starts working. When the user can make the driving motor 13 work, it can drive the driving gear 14 to rotate. Since the driving gear 14 and the circular gear ring 11 are meshed, the circular gear ring 11 and the rotating ring 4 can be driven to rotate, thereby driving the translation telescopic rod 5 and the welding gun 10 to rotate. After the translation telescopic rod 5 works, it can drive the welding gun 10 to translate. If the user makes the rotating motor 15 work, it can drive the rotating seat 7 and the U-shaped connecting plate 8 to rotate, so that the welding gun 10 can rotate. In summary, the use angle of the welding gun 10 is easy to adjust and has strong adaptability.
