[0002] Welding, also known as fusion, is a common metal parts manufacturing process and technology. Thin plate welding is a common process in product processing. Because thin plates are flat cross-section sheets with a large width-to-thickness ratio, they are difficult to secure during welding. Furthermore, welding deformation is prone to occur during welding, ultimately leading to a significant deviation in the angle formed by the two sheets after welding. This can cause uncontrollable weld dimensions, leading to product repair or scrapping, low yield rates, low welding efficiency, and high production costs. Utility Model Content

[0032] The technical solution protected by the present utility model is described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 As shown, an I-shaped plate 6 includes: a first end plate 61 and a second end plate 62 parallel to each other, a plurality of partitions 63 are welded between the first end plate 61 and the second end plate 62, and an I-shaped structure is arranged between the partitions 63 and the end plates on both sides.

[0034] like Figure 2As shown, the present application proposes a plate welding auxiliary tooling for auxiliary welding of the above-mentioned I-shaped plates, which includes a machine 1 and a number of lifting fixtures 5 for clamping end plates. A partition moving area 101 is provided on the machine 1, and an end plate lifting area 102 is provided above the partition moving area 101. A partition feeding mechanism 2 is provided in the partition moving area 101 for delivering the upright partition to the designated welding position; two sets of mutually parallel lifting mechanisms 3 are provided in the end plate lifting area 102 for lifting the end plate into the end plate lifting area 102, and in this area, the end plate can be manually assisted to flip 180° so as to weld the other end plate; an end plate pressing mechanism 4 is provided between the partition moving area 101 and the end plate lifting area 102 for pressing the end plate above the partition to improve the stability during the welding process.

[0035] like Figure 3 As shown, the lifting fixture 5 includes a clamping plate 51. A bearing 52 is disposed at one axial end of the clamping plate 51. A connecting rod 53 is provided within the inner ring of the bearing 52. The clamping plate rotates relative to the connecting rod 53 via the bearing 52. A lifting ring 54 is disposed at the end of the connecting rod 53 away from the clamping plate 51. A clamping groove 511 is defined at the end of the clamping plate 51 away from the bearing 52. The height of the clamping groove 511 matches the thickness of the end plate, allowing the lifting fixture 5 to be secured to the side of the end plate. When two sets of lifting fixtures 5 are secured on opposite sides of the end plate, and both sets are located at the front and rear ends of the end plate, the end plate can be lifted smoothly by lifting the lifting fixtures 5. When one set of lifting fixtures 5 is secured in the middle of opposite sides of the end plate, the end plate can be lifted by lifting the lifting fixtures 5 and then manually flipped 180°. This effectively saves manpower during the flipping process, and the clamping of the lifting fixtures 5 improves the stability of the end plate during the flipping process.

[0036] like Figure 2 and 4As shown, the partition feeding mechanism 2 includes a placement base plate 211, on which two mutually parallel base plates 212 are vertically arranged. A receiving area is formed between the two base plates 212, and a clamping plate 213 is built into the receiving area and is parallel to the base plates 212. A clamping cylinder 214 is provided on any base plate 212, and the clamping cylinder 214 drives the clamping plate 213 toward and away from the other base plate 212, forming a clamping area between the clamping plate 213 and the other base plate 212. In this embodiment, the base plates 212 include a first base plate 2121 and a second base plate 2122 that are parallel to each other. The clamping cylinder 214 is fixed to the first base plate 2121, and the clamping cylinder 214 drives the clamping plate 213 toward and away from the second base plate 2122, forming a clamping area between the clamping plate 213 and the second base plate 2122. The partition is placed in the clamping area, and the clamping cylinder 214 drives the clamping plate 213 toward the second substrate 2122, clamping the partition between the clamping plate 213 and the second substrate 2122. Preferably, in this embodiment, with the second substrate 2122 as the clamping reference surface, the clamping plates 213 and the clamping cylinders 214 are arranged in multiple groups at intervals along the extension direction of the first substrate 2121. The multiple clamping plates 213 clamp the partition simultaneously, thereby applying clamping force to multiple locations along the length of the partition, thereby improving the clamping stability of the partition.

[0037] like Figure 2-5 As shown, the winding member 31 includes an upright truss 311, which is provided with a rotatable shaft 312 and a rotary drive 313 that drives the shaft 312 to rotate. A plurality of drums 314 are provided on the shaft 312 at intervals along its length. A steel wire rope (not shown) is wound around the drums 314, and the free end of the steel wire rope is connected to the lifting ring 54 of the lifting fixture 5. The rotary drive 313 drives the shaft 312 to rotate, that is, drives the drums 314 on the shaft 312 to rotate synchronously, thereby releasing or reeling in the steel wire rope: the drums 314 on both sides synchronously reel in the steel wire rope, making the steel wire rope taut, driving the lifting fixture to rise synchronously and lifting the end plate; the drums 314 on both sides synchronously release the steel wire rope, making the steel wire rope taut, and causing the end plate to descend.

[0038] like Figure 2-5 As shown, preferably, there are third slide rails 32 on the opposite sides of the machine 1, and both ends of the two sets of upright trusses 311 along the length direction are slidably set on the third slide rails 32, so that the upright trusses 311 can slide freely along the third slide rails 32, and the distance between the two sets of winding members 31 can be adjusted to adapt to end plates of different widths, thereby improving the applicability of the auxiliary tooling.

[0039] like Figure 2-6As shown, the end plate pressing mechanism 4 includes a pressing member 41 and a second transverse member 42 that drives the pressing member 41 to move in the horizontal direction. The pressing member 41 includes a connecting plate 411 movably arranged on the machine 1, and a pressing cylinder 412 is arranged on the connecting plate 411. The output end of the pressing cylinder 412 passes through the connecting plate 411 downward and is connected to a pressing plate 413. During the welding process, the second transverse member 42 drives the pressing member 41 to move to the welding position, and the pressing cylinder 412 drives the pressing plate 413 to move downward. The pressing plate 413 is pressed above the end plate so that the welding point of the end plate and the partition are tightly abutted to ensure a smooth welding process. Preferably, a plurality of pressing cylinders 412 and pressing plates 413 are arranged on the connecting plate 411, and the pressing cylinders 412 are arranged at intervals along the length direction of the partition to ensure that the welding point of the partition and the end plate is evenly subjected to the abutting force.

[0040] Preferably, in this embodiment, a right-angle limit plate (not shown) is provided on the machine platform to limit the placement position of the end plate, and one corner of the end plate is correspondingly abutted against the right-angle limit plate.

[0041] In this embodiment, the first and second transverse moving members may be a combination of a cylinder, a guide rail, and a slider, or a servo motor, a lead screw, and a slider, without specific limitation. The rotary drive element may be a servo motor-driven gear module, a rotary cylinder, or the like, without specific limitation.

[0042] Working principle:

[0043] In the initial state, the partition feeding mechanism 2, the end plate pressing mechanism 4 and the hoisting and lifting mechanism 3 are all placed on one side of the machine platform 1 for manual loading.

[0044] The first partition is manually placed in the clamping area, the clamping cylinder 214 drives the clamping plate 213 to move, clamping the first partition, and the first transverse member 22 moves, driving the clamping member 21 and the clamped first partition to move to the set welding position.

[0045] The first end plate is manually placed above the upright first partition, and the lifting clamps 5 are clamped on both sides of the first end plate, with two sets of lifting clamps 5 on each side. The winding member 31 winds up the wire rope to maintain the stability of the first end plate; the second transverse member 42 drives the downward pressure member 41 to move to the set welding position, and the downward pressure cylinder 412 drives the downward pressure plate 413 to be pressed on the first end plate, pressing the first end plate and the first partition to weld the first end plate and the first partition.

[0046] After the first end plate and the first partition are welded, the downward pressure cylinder 412 drives the downward pressure plate 413 to rise, and the second transverse moving member 42 drives the downward pressure member 41 to retreat to the side of the machine 1, and the winding member 31 continues to wind the wire rope to lift the first end plate and the first partition welded under the first end plate to the end plate lifting area 102; the second partition is loaded manually, and the first transverse moving member 22 continues to transport the second partition to the designated welding position; the winding member 31 releases the wire rope, the first end plate descends, and the downward pressure member 41 moves to the welding position to press and weld the second partition; this reciprocating process completes the welding of all partitions and the first end plate.

[0047] The lifting clamps 5 on both sides of the first end plate are manually moved to the middle of the first end plate. A set of lifting clamps 5 is clamped on each side. The winding member 31 winds the wire rope and lifts the first end plate to the end plate lifting area 102. The first end plate is manually flipped 180° so that the partition on the first end plate faces upward.

[0048] The winding member 31 releases the wire rope, and the first end plate descends onto the machine platform 1. One end of the first end plate abuts against the right-angle limit plate. The second end plate is manually placed on the upper end of the partition, and the second end plate and the partition are welded to complete the welding of the plate.

[0049] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
