Internal angle welding robot 3, used for welding the internal angles of angle iron weldments; The outer corner welding robot arm 4 is used to weld the outer corners of angle iron weldments. The inner corner welding robot arm 3 and the outer corner welding robot arm 4 are respectively installed on both sides of the top of the machine platform 1. A stepper motor 33 is fixedly installed on the top wall of the machine platform 1. The output end of the stepper motor 33 passes through the top of the machine platform 1 and is fixedly installed with the rotation center of the column 2.

[0020] In this embodiment, the clamping assembly includes a C-shaped plate 11 fixedly mounted on the outer periphery of the column 2, and a support sleeve 12 is fixedly mounted on the outer surface of the C-shaped plate 11. The support sleeve 12 is sleeved on the outside of the support shaft 5, and an axially movable sleeve 13 is sleeved on the outside of the support sleeve 12. The support sleeve 12 is fixedly mounted with a limit strip along its axial outer periphery, and a limit groove matching the limit strip is provided on the inner wall of the sleeve 13. The limit strip is slidably mounted on the inner wall of the limit groove to ensure the stability of the movement of the sleeve 13 and prevent it from rotating. A movable plate 14 is rotatably mounted on the end of the sleeve 13 away from the C-shaped plate 11 through a bearing, and both end ends of the movable plate 14 are hinged with a clamping rod 15, and the end of the clamping rod 15 away from the movable plate 14 is fixedly mounted with a member matching the angle iron welding piece. An L-shaped clamping plate 16 is provided, and a locking assembly is installed between the clamping rod 15 and the trapezoidal bracket 6. The locking assembly includes a fixed plate 18 fixedly mounted on the outer surface of the trapezoidal bracket 6. A V-shaped groove 19 is provided on the outer surface of the fixed plate 18. A boss 17 matching the V-shaped groove 19 is fixedly mounted on the outer surface of the clamping rod 15. The boss 17 slides on the inner wall of the V-shaped groove 19. A push-pull assembly is installed between the sleeve 13 and the support ring 24. The push-pull assembly includes a push-pull plate 27 fixedly mounted on the lower surface of the sleeve 13. A guide column 28 is fixedly mounted on the upper surface of the push-pull plate 27. A push-pull groove matching the guide column 28 is provided on the lower surface of the support ring 24. The guide column 28 slides on the inner wall of the push-pull groove. The push-pull groove is composed of a V-shaped groove 29 and a semi-annular groove 30 connected end to end.

[0021] When in use, two plates to be welded into angle irons are placed on both sides of the inner part of the trapezoidal bracket 6 from the front of the machine 1, and the welding edges of the two plates are aligned on the inner side of the V-shaped bracket 8. After the two plates to be welded are placed, the stepper motor 33 drives the column 2 to rotate 120 degrees as a whole, so that the column 2 can drive the trapezoidal bracket 6 and the V-shaped bracket 8 to move as a whole through the support shaft 5. In the process of the trapezoidal bracket 6 and the V-shaped bracket 8 driving the plates to move, the guide column 28 installed on the sleeve 13 through the push-pull plate 27 will slide inside the push-pull groove, so that the guide column 28 moves from the V-shaped groove 29 to the semi-annular groove 30, thereby making the guide column 2 8 can pull the sleeve 13 to move through the push-pull plate 27, so that the sleeve 13 pulls the clamping rod 15 to move through the movable plate 14. Since the outer side of the clamping rod 15 is slidably installed through the protruding column 17 and the inner wall of the V-shaped groove 19, the clamping rod 15 can first move closer to the trapezoidal bracket 6 under the guidance of the protruding column 17 and the V-shaped groove 19 when moving, so that the L-shaped clamping plate 16 is swung into the inner side of the trapezoidal bracket 6. As the sleeve 13 continues to be pulled, the L-shaped clamping plate 16 will be against the side of the plate to be welded, clamping the plate to the inner side of the trapezoidal bracket 6, so that the plate can be turned over later, and it can prevent the plate from shifting during the welding operation, affecting the welding effect.

[0022] In this embodiment, a flip mechanism is installed between the support shaft 5 and the top of the machine 1. The flip mechanism includes a worm gear 20 fixedly mounted on the outer surface of the support shaft 5, and a worm 21 meshing with the worm gear 20 is rotatably mounted between the outer surfaces of the opposite sides of the C-shaped plate 11. The self-locking characteristics of the worm gear 20 and the worm 21 can ensure that the support shaft 5 will not rotate at will; a transmission gear 22 is fixedly mounted on the rotation center of the bottom end of the worm 21, and a plurality of support rods 23 are fixedly mounted on the upper surface of the machine 1. A support ring 24 is fixedly mounted on the top of the plurality of support rods 23. An incomplete inner gear ring 25 and an incomplete outer gear ring 26 are fixedly mounted on the upper surface of the support ring 24 respectively. The incomplete outer gear ring 26 is arranged on the inner side of the incomplete inner gear ring 25, and the transmission gear 22 is arranged between the incomplete inner gear ring 25 and the incomplete outer gear ring 26, and the transmission gear 22 intermittently meshes with the incomplete inner gear ring 25 and the incomplete outer gear ring 26.

[0023] When the column 2 drives the trapezoidal bracket 6 to move to the teeth of the incomplete internal gear ring 25 through the support shaft 5, the corresponding transmission gear 22 will engage with the teeth of the incomplete internal gear ring 25, so that the transmission gear 22 can drive the worm 21 to rotate, and the worm 21 drives the worm wheel 20 engaged with it to rotate, so that the worm wheel 20 drives the support shaft 5 to rotate 180°, and the support shaft 5 drives the trapezoidal bracket 6 and the V-shaped bracket 8 to flip 180° as a whole, so that the outer joint seam of the two plates can be flipped to the top, so as to facilitate the subsequent welding operation by the external corner welding robot arm 4.

[0024] In this embodiment, a pulling-away assembly is installed between the trapezoidal bracket 6 and the V-shaped bracket 8. The pulling-away assembly includes a fixing rod 7 fixedly installed on the back side of the trapezoidal bracket 6. The fixing rod 7 passes through the outer surface of the V-shaped bracket 8 and is slidably installed with it. A limiting ring 9 is fixedly installed on one end of the fixing rod 7 away from the trapezoidal bracket 6. A tension spring 10 is sleeved on the outer surface of the fixing rod 7, and the tension spring 10 is fixedly installed between the limiting ring 9 and the V-shaped bracket 8.

[0025] When the V-shaped bracket 8 flips over, the top column 31 will separate from the outer side of the semi-annular plate 32, so that the V-shaped bracket 8 is no longer blocked by the semi-annular plate 32, and the V-shaped bracket 8 is pulled away from the bottom of the trapezoidal bracket 6 under the tension of the tension spring 10, so as to expose the outer joint seam of the two plates, which is convenient for welding operations.

[0026] In this embodiment, a pushing assembly is installed between the V-shaped bracket 8 and the top of the machine 1. The pushing assembly includes a semi-annular plate 32 fixedly installed on the top of the machine 1. The end of the semi-annular plate 32 close to the outer corner welding robot arm 4 is set as an inclined surface. A top column 31 is fixedly installed on the back side of the V-shaped bracket 8, and the top column 31 intermittently abuts against the outer side of the semi-annular plate 32.

[0027] In the initial position, the top column 31 installed on the back side of the V-shaped bracket 8 abuts against the outer side of the semi-annular plate 32, so that the V-shaped bracket 8 and the bottom of the trapezoidal bracket 6 are closed to form a V-shaped placement cavity for placing plates.

[0028] In this embodiment, a limit bar is fixedly installed along the axial periphery of the support sleeve 12, and a limit groove matching the limit bar is opened on the inner wall of the sleeve 13. The limit bar and the inner wall of the limit groove are slidably installed to ensure the stability of the movement of the sleeve 13 and prevent it from rotating.

[0029] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when in use, two plates to be welded into angle irons are placed on both sides of the inner side of the trapezoidal bracket 6 from the front of the machine 1, and the welding edges of the two plates are aligned on the inner side of the V-shaped bracket 8. After the two plates to be welded are placed, the stepper motor 33 drives the column 2 to rotate 120 degrees as a whole, so that the column 2 can drive the trapezoidal bracket 6 and the V-shaped bracket 8 to move as a whole through the support shaft 5. In the initial position, the top column 31 installed on the back side of the V-shaped bracket 8 is abutted against the outer side of the semi-annular plate 32, so that the V-shaped bracket 8 and the bottom of the trapezoidal bracket 6 are closed to form a V-shaped placement cavity for placing the plates; When the plate is moved by the ladder bracket 6 and the V-shaped bracket 8, the guide post 28 installed on the sleeve 13 through the push-pull plate 27 will slide inside the push-pull groove, so that the guide post 28 moves from the V-shaped groove 29 to the semi-annular groove 30, so that the guide post 28 can pull the sleeve 13 to move through the push-pull plate 27, so that the sleeve 13 pulls the clamping rod 15 to move through the movable plate 14. Since the outer side of the clamping rod 15 is slidably installed by the protruding post 17 and the inner wall of the V-shaped groove 19, the clamping rod 15 can first move closer to the ladder bracket 6 under the guiding action of the protruding post 17 and the V-shaped groove 19 when moving, so that the L-shaped clamping plate 16 is swung into the inner side of the ladder bracket 6. As the sleeve 13 continues to be pulled, the L-shaped clamping plate 16 will abut against the side edge of the plate to be welded, clamping the plate to the inner side of the ladder bracket 6, so that the plate can be turned over later, and it can prevent the plate from shifting during the welding operation, affecting the welding effect; After the trapezoidal bracket 6 drives the plates to be welded to move 120°, the inner corner welding robot arm 3 welds the inner joint between the two plates; After the inner corner welding robot arm 3 completes the welding, the stepper motor 33 continues to drive the column 2 to rotate 120 degrees so that the outer corner welding robot arm 4 can weld the outer joint seams of the two plates. When the column 2 drives the trapezoidal bracket 6 to move to the teeth of the incomplete internal gear ring 25 through the support shaft 5, the corresponding transmission gear 22 will mesh with the teeth of the incomplete internal gear ring 25, so that the transmission gear 22 can drive the worm 21 to rotate, so that the worm 21 drives the worm wheel 20 meshing with it to rotate, so that the worm wheel 20 drives the support shaft 5 to rotate 180°, so that the support shaft 5 drives the trapezoidal bracket 6 and the V-shaped bracket 8 to flip 180° as a whole, so that the outer joint seam of the two plates is flipped to the top, so as to facilitate the subsequent welding operation by the external corner welding robot arm 4; When the V-shaped bracket 8 is turned over, the top column 31 will separate from the outer side of the semi-annular plate 32, so that the V-shaped bracket 8 is no longer blocked by the semi-annular plate 32. The V-shaped bracket 8 is pulled away from the bottom of the trapezoidal bracket 6 under the tension of the tension spring 10, so as to expose the outer joint seam of the two plates, which is convenient for welding operation. After the inner and outer joints between the two plates are welded, the stepper motor 33 continues to drive the column 2 to rotate 120 degrees, so that the trapezoidal bracket 6 returns to its original position as a whole. During the process of the trapezoidal bracket 6 returning to its original position, the corresponding transmission gear 22 will engage with the teeth of the incomplete external gear ring 26, so that the transmission of the worm 21 and the worm wheel 20 drives the trapezoidal bracket 6 to rotate 180 degrees as a whole through the support shaft 5, so that the V-shaped bracket 8 is turned over to the bottom again, so that the welded angle iron can be taken out; At the same time, the top column 31 installed on the back side of the V-shaped bracket 8 will abut against the inclined surface of the end of the semi-annular plate 32, so that the V-shaped bracket 8 can be pushed to the bottom of the trapezoidal bracket 6 again, so that the plate to be welded can be received and placed next time; In addition, the guide column 28 installed on the sleeve 13 through the push-pull plate 27 will also move from the semi-annular groove 30 to the apex of the V-shaped groove 29 again, so that the sleeve 13 and the movable plate 14 push the clamping rod 15 to move outward, so that the L-shaped clamping plate 16 no longer abuts against the side of the plate. As the clamping rod 15 continues to move outward, the protruding column 17 installed on the clamping rod 15 will move to the outward extension section of the V-shaped groove 19, so that the clamping rod 15 can drive the L-shaped clamping plate 16 to swing to the outside of the trapezoidal bracket 6, thereby preventing the L-shaped clamping plate 16 from blocking the side of the trapezoidal bracket 6 and affecting the removal of the angle iron.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
