With the increasing demand for space utilization, the types and functions of racks are becoming increasingly diversified. Metal racks have the advantages of being strong and durable, strong in load-bearing capacity, and simple in design. The production process of metal racks requires the use of welding devices, and the existing rack welding devices still have some shortcomings.

[0003] The utility model patent with the publication number CN213163742U discloses a welding tool for processing a rack, including a pedestal and a welding table. A working surface is arranged on the top of the pedestal, and a rack is arranged in the middle of the working surface. The two ends of the outer side of the rack are connected with fixed seats, and a first slide groove is provided at the bottom of the fixed seat. The welding table is arranged at the top edge of the working surface, and a welding seat is connected to the middle end of the welding table. Welding heads are arranged on both sides of the bottom of the welding seat. Sliding seats are arranged on both sides of the top of the working surface, and a second slide groove is provided at the bottom of the sliding seat. Blocks are arranged on both sides of the top of the sliding seat, and a partition is arranged in the middle of the top of the sliding seat. In the welding tool for processing a rack, two sliding seats are arranged on the working surface. During the movement of the rack, a large gap can be reserved, so that the two sliding seats can simultaneously drive the partition and the rack to be assembled, which enables the equipment to weld two partitions at the same time. Although the above device can weld two partitions at the same time, it cannot adaptably adjust the welding position and welding spacing according to the length and width of the partition when in use. The adaptability during welding is insufficient, and the welding efficiency is low. It is impossible to weld while supporting the partition to ensure welding accuracy.

[0004] The invention patent with the publication number of CN110900080B discloses an auxiliary positioning device for welding a storage rack, comprising a base and a first limiting assembly arranged on the base for opening and limiting the two ends of the support frame of the storage rack along the length direction; the first limiting assembly comprises a first motor arranged in the middle of the base and a first screw rod respectively arranged on both sides of the first motor, and a support block for supporting two first screw rods is arranged on both sides of the first motor along the length direction on the base, and the output end of the first motor is meshed with the two first screw rods through a first bevel gear and a second bevel gear. The first movable seat fixedly connected to the nut on the first screw rod is slidably arranged on the two support blocks, which has the effect of enhancing the stable positioning of the support frame. Although the above device can realize the positioning function, it cannot use the four support rods on the edge of the storage rack for guidance during welding, and cannot adaptably adjust the position of the guide structure according to the spacing of the rods around the storage rack, and the existing welding device cannot realize one-time welding of the rods and storage plates around the storage rack by rotating the support structure, and the welding efficiency is low, and the four rods of the storage rack cannot be calibrated while welding.

[0052] Embodiment 3:

[0053] The schemes in Example 1 and Example 2 are further introduced below in combination with specific working methods, as described below for details:

[0054] Specifically, when the welding device for processing a storage rack is used: Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, Figure 1The dotted cylinders around the device are four rack rods, and the rectangular structure in the middle of the dotted line is the rack plate. First weld the top plate, and then you can install the device according to Figure 1 The position and spacing of the two sets of first guide rings 7 and the two sets of second guide rings 12 are adjusted according to the length and width of the rack. Figure 7 and Fig. 9 As shown, the fourth motor 24 drives the fixed shaft 25 to rotate, thereby driving the second connecting plate 8 to rotate above the first connecting plate 1, changing the angle between the first connecting plate 1 and the second connecting plate 8 to adapt to the welding work of the racks with different aspect ratios. Fig. 9 The initial state of the first spring 6 is a compressed state. When the first traction steel rope 5 is no longer pulled, the first spring 6 on the first outer bushing 3 will reset to make the first outer bushing 3 slide on the connecting block 2, thereby adaptively adjusting the position of the first guide rings 7 on both sides of the first connecting plate 1. The first traction steel rope 5 runs through the interior of the connecting block 2. A second connecting plate 8 is rotatably installed above the first connecting plate 1. A second outer bushing 9 is slidably installed on the second connecting plate 8. A second spring 11 is fixedly connected between the second connecting plate 8 and the second outer bushing 9. A second traction steel rope 10 is fixedly connected to the inner wall of the second outer bushing 9. A second guide ring 12 is rotatably connected to the second outer bushing 9. Fig.10 The second spring 11 is in a compressed state. When the top of the second traction steel rope 10 moves downward, the second outer bushing 9 will slide under the elastic force of the second spring 11, thereby changing the spacing between the second guide rings 12 on both sides of the second connecting plate 8. Therefore, the device can change the position of the top of the first traction steel rope 5 and the second traction steel rope 10 by extending or shortening the second electric push rod 15, thereby changing the spacing between the two adjacent first guide rings 7 and the two adjacent second guide rings 12, so that the device can adapt to the welding of racks with different aspect ratios.

[0055] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11As shown, the storage plate of the storage rack is placed on the top plate 16, and the storage plate is adsorbed by the suction cup 17. The first synchronous wheel 1303 is driven to rotate by the first motor 1302, and the first synchronous wheel 1303 drives the second synchronous wheel 1305 and the rotating wheel 1306 to rotate through the synchronous belt 1304. When the rotating wheel 1306 rotates, the friction pattern of the protruding part of the rotating wheel 1306 can abut against the rods around the storage plate, thereby driving the device to move up and down as a whole. After moving to a suitable position, it is welded through the driving component 19 on the fixed rod 14, and the worm 1904 is driven to rotate by the third motor 1903, and the worm 1904 drives the worm wheel 1905 to rotate. The worm gear 1905 can make the third electric push rod 2001 rotate axially when rotating, thereby changing the initial position of the welding tool 21 and the welding head 22, so as to accurately adjust the welding angle of the device. When the device is in use, the adjusting bolt 2006 can be screwed into the first connecting shell 2002 or the second connecting shell 2004, so that the device can press the first ball shaft 2003 or the second ball shaft 2005 after tightening the adjusting bolt 2006, so that the angles of the two ball shafts on the device remain fixed after adjustment. The first ball shaft 2003 is used to change the initial height of the second ball shaft 2005 and the welding tool 21, and the second ball shaft 2005 is used to change the angle of the welding tool 21. The second motor 1901 drives the fixing frame 1902 and the supporting assembly 20 to rotate, so as to perform circumferential welding, so as to weld four points at one time later. When the third electric push rod 2001 rotates along its own axis, the lap ring 2007 can support the third electric push rod 2001. When the third electric push rod 2001 rotates along the axis of the device, the swivel ring 18 can rotate on the top plate 16 to support the third electric push rod 2001. After welding one of the storage plates, a new storage plate is placed on the top plate 16 and the above steps are repeated for the second welding.

[0056] The above embodiments are only used to illustrate the present invention, but not to limit the present invention.
