[0047] The present invention also discloses a method for using a high-efficiency turntable combined welding device, which specifically comprises the following steps:

[0048] Step 1: Loading and feeding of welding plates: The device is divided into four areas in a clockwise direction, namely, the loading area, the front welding area, the back welding area and the material removal area. The front is the loading area. The two plates to be welded are placed in advance, respectively, with the front side as the reference, and the two are located on the top of the bottom bevel gear 805;

[0049] Step 2, welding seam combination: the rotating mechanism 4 is used to equidistantly transform the position of the rotating table 3, so that the above-mentioned plate is transformed to the left front welding area. During the transformation of the position of the rotating table 3, the rotating table 3 uses the center clamping mechanism 7 to centrally merge and clamp the two above-mentioned plates, so that the weld between the plates is in the welding area of ​​the welding gun 6, and the multi-axis robot arm 5 and the welding gun 6 cooperate to perform automatic front welding;

[0050] The specific steps are: according to Figure 1 , Figure 3 , Figure 4 , Figure 6 , Fig. 9 , Fig.15 , Fig.16 As shown, the stepper motor 401 is started, and the stepper motor 401 drives the third gear 402 to rotate a specified number of times, so that the fourth gear 403 is meshed with the third gear 402, and then the turntable 3 is driven to rotate a quarter of a turn, thereby causing the front side delivery area to be transferred to the front welding area. The rotation of the turntable 3 synchronously drives the loading plate 713 to rotate, and the loading plate 713 synchronously drives the double-headed top frame 715 to rotate. When the double-headed top frame 715 rotates, it will transfer from the area between the concave surface of the inner convex ring 718 and the convex surface of the convex edge circular plate 717 to the area between the convex surface of the inner convex ring 718 and the concave surface of the convex edge circular plate 717, thereby causing the double-headed top frame 715 to move, and the movement of the double-headed top frame 715 drives the squeeze The pressing and oblique frame 716 squeezes the movable rod 714, causing the two movable rods 714 to move face to face. The movement of the movable rod 714 synchronously drives the multi-faceted rod 703 to move, thereby causing the two multi-faceted rods 703 to synchronously drive the wide-face clamping plate 704 to clamp the two plates, causing the welds of the two plates to fit together. During the movement of the wide-face clamping plate 704, the wide-face clamping plate 704 will also squeeze the oblique convex surface of the narrow-face fastening frame 712, causing the narrow-face fastening frame 712 to synchronously clamp the two narrow faces of the plate in the center. After the two plates are merged in the center, the front welds of the two plates can be welded by the multi-directional drive of the left multi-axis robot arm 5 and the welding of the welding gun 6.

[0051] Step 3: After the front welds of the two plates are welded in step 2, the rotary mechanism 4 is continuously driven to cause the rotary table 3 to transfer the front welded plate from the front welding area to the back welding area. During the transfer process, the plate is automatically turned over while being clamped through the coordinated cooperation of the center clamping mechanism 7 and the flipping mechanism 8, so that the back weld is exposed in the back welding area, and the back weld is automatically welded through the cooperation of the rear multi-axis robot arm 5 and the welding gun 6;

[0052] The specific steps are: according to Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, after the front weld seams of the two plates are welded in step 2, the rotary mechanism 4 is continuously driven to transfer the plate after the front weld to the back welding area on the rear side, and the rotary table 3 is continuously driven to rotate along with the rotary mechanism 4. At this moment, the loading plate 713 in the front welding area continues to rotate along with the turntable 3, and the loading plate 713 synchronously drives the first gear 803 and the second gear 804 to move in a circle. During the movement, the first gear 803 and the second gear 804 installed at different heights are respectively connected with the first arc-shaped semi-toothed ring 812 When the meshing stroke is completed with the second arcuate semi-toothed ring 811, the first gear 803 is meshed with the first arcuate semi-toothed ring 812 and the second gear 804 is meshed with the second arcuate semi-toothed ring 811, the short rod 801 and the long rod 802 are synchronously driven to rotate, and the short rod 801 and the long rod 802 respectively drive the bevel gear 805 to rotate, and the two adjacent bevel gears 805 rotate and mesh, so that the inner polygonal cylinder 702 drives the polygonal rod 703, the wide clamping plate 704, the narrow fastening frame 712 and the support plate 705 to turn over 180 degrees, and the welding part is turned over;

[0053] When the top support plate 705 and the bottom support plate 705 are turned over and exchanged, the top support plate 705 will squeeze the support rod 708 by turning over, causing the support rod 708 to elastically slide back to leave a turning space for the top support plate 705, and during the turning process, the support plate 705 in the top unfolded state is guided by the inclined guide inclined plate 707, so that when the bottom is turned over, the support plate 705 automatically elastically displaces in the reverse direction and turns into a supporting state. When the bottom support plate 705 turns over the top, it relies on the sliding blocking track of the guide straight rod 809 and the arc rod 810, so that after the bottom support plate 705 is turned over 180 degrees in a balanced state, it can break away from the blocking of the arc rod 810 and elastically unfold on the top of the support rod 708 by itself;

[0054] in Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 , Fig.12 , Fig.13 , Fig.14 , Fig.16As shown, before the first gear 803 and the first arcuate semi-toothed ring 812 and the second gear 804 and the second arcuate semi-toothed ring 811 start to mesh, the two limit racks 903 (it should be noted that the two limit racks 903 provided at the bottom of the single cross mounting groove 701 are respectively installed in the high-position annular groove frame 901 and the low-position annular groove frame 902) in the rear position adjustment slider 807 at this moment, which are interlaced with the limit socket 904 and have different installation heights, will successively move in annularly inside the high-position annular groove frame 901 and the low-position annular groove frame 902 respectively along with the rotation of the turntable 3, and before the first gear 803 and the first arcuate semi-toothed ring 812 and the second gear 804 and the second arcuate semi-toothed ring 811 start to mesh, the two limit racks 903 will slide in annularly into the high-position annular groove frame 901 and the low-position annular groove frame 902 in advance. When the support plate 705 is turned over, the support rod 708 can automatically release the stable support state so that the support rod 708 can retract elastically to leave space for the support plate 705 to turn over. After the first gear 803 is engaged with the first arcuate semi-toothed ring 812 and the second gear 804 is engaged with the second arcuate semi-toothed ring 811, the two limit brackets 903 will rotate to return to the original annular sliding height of the high-position annular groove frame 901 and the low-position annular groove frame 902, respectively, so that the limit bracket 903 continues to cooperate with the limit plug hole 904 pinion, and the support rod 708 is reinforced to ensure the balance and stability of the overall clamping of the multi-faceted rod 703, the wide-surface clamping plate 704, the support plate 705 and the narrow-surface fastening frame 712.

[0055] Step 4: After the welding of the back seam of the plate in step 3 is completed, the rotary mechanism 4 is continued to be driven, so that the rotary table 3 drives the plate completed by the welding machine to be transferred from the back welding area to the right material taking area. After the position transfer is completed, the center clamping mechanism 7 automatically releases the plate from the center fastening;

[0056] The specific steps are: according to Fig. 9 and Fig.16 As shown, the rotating mechanism 4 is continued to be driven, so that the turntable 3 is caused to rotate the plate with both sides welded equidistantly to the material taking area, and the rotation of the turntable 3 continues to drive the loading plate 713, the double-headed top frame 715 and the extrusion bevel frame 716 to move in a circle. During the movement, the double-headed top frame 715 is transferred from the area between the convex surface of the rear inner convex ring 718 and the concave surface of the convex edge circular plate 717 to the area between the concave surface of the right inner convex ring 718 and the convex surface of the convex edge circular plate 717, thereby completing the resetting of the extrusion bevel frame 716. The resetting of the extrusion bevel frame 716 synchronously drives the resetting of the movable rod 714, and the polygonal rod 703 is successively retracted into the inner polygonal cylinder 702, so that the wide-faced clamping plate 704 and the narrow-faced fastening frame 712 are successively reset, thereby releasing the centering fastening fit of the plate.
