DETAILED DESCRIPTION
[0018] The following is combined with Figure 1-3 This application is described in further detail.
[0019] The present application embodiment discloses a forklift fork frame 7-axis arc welding robot. Figure 1, including a safety fence 1, a 6-axis industrial robot 3, a 1-axis flip welding positioner 5, and a number of reducers 17 arranged correspondingly on the 6-axis industrial robot 3. The safety fence 1 is used to block the entry of irrelevant external personnel and prevent welding arc from injuring people. A mounting base 2 is fixedly installed inside the safety fence 1, and a base 6 is installed on the mounting base 2. The 6-axis industrial robot 3 is connected to the base 6, and the bottom of the 6-axis industrial robot 3 can be supported by the base 6. The 6-axis industrial robot 3 is provided with a welding gun 4, and welding work is performed by the welding gun 4.
[0020] like Figure 2 As shown, the output end of the base 6 is connected to the first motion axis 7, the second motion axis 9 is installed on the first motion axis 7, the second motion axis 9 is externally connected to a robotic arm 8, the end of the robotic arm 8 away from the second motion axis 9 is connected to the third motion axis 10, the third motion axis 10 is installed with a support arm 11, one end of the support arm 11 is installed with a connector 12, the welding gun is clamped by the connector 12 to reach the designated welding area, and the welding gun posture is adjusted to complete the welding.
[0021] Several reducers 17 are correspondingly arranged on the first motion shaft 7, the second motion shaft 9 and the third motion shaft 10. Specifically, the reducer 17 corresponding to the first motion shaft 7, the reducer 17 corresponding to the second motion shaft 9 and the reducer 17 corresponding to the third motion shaft 10 are all exposed to the outside.
[0022] like Figure 3 As shown, a 1-axis flip welding positioner 5 is installed at the front end of the 6-axis industrial robot 3, and two 1-axis flip welding positioners 5 are provided and symmetrically distributed. A transmission shaft 14 is rotatably installed inside the two 1-axis flip welding positioners 5, and an engine 13 is installed on the outer wall of one of the 1-axis flip welding positioners 5. The output end of the engine 13 extends into the 1-axis flip welding positioner 5 and is transmitted to the transmission shaft 14;
[0023] The ends of the two transmission shafts 14 that are close to each other are connected to a flip-shift turntable 15, and the inner walls of the ends of the two flip-shift turntables 15 that are close to each other are fixed with mounting plates 16. Suitable welding fixtures can be fixed on the mounting plates 16 to clamp the workpieces according to the shape and size of the workpieces.
[0024] The implementation principle of the 7-axis arc welding robot of the forklift fork frame of the present application is as follows: when working, open the sliding door in front of the safety fence 1, cooperate with the welding gun 4 of the welding system installed inside the connector 12, turn on the power of the equipment, start the 6-axis industrial robot 3, and then install a suitable welding fixture on the mounting plate 16 inside the 1-axis flip welding positioner 5 according to the size of the product to be welded, then install the product to be welded into the welding fixture, position and press it, exit the safety fence 1, close the sliding door, and then start the 6-axis industrial robot 3 to start according to the predetermined program. The engine 13 starts to move and starts the engine 13 at the same time. The engine 13 drives the transmission shaft 14 inside the 1-axis flip welding positioner 5 to rotate, which in turn drives the flip positioning turntable 15 to flip. At this time, the workpiece clamped inside can be flipped, and the weld of the workpiece is adjusted to the best position. At the same time, the 6-axis industrial robot 3 drives the welding gun 4 to start welding at the best angle. After welding is completed, the 6-axis industrial robot 3 and the 1-axis flip welding positioner 5 all return to the safe standby position. The operator opens the safety fence 1, removes the welded workpiece, and replaces it with the next product to be welded.
