Transverse welding refers to a process of welding a weld in a horizontal direction on a vertical or inclined plane. The transverse welding is usually used for welding and manufacturing the circumferential welding seams of large-scale pressure containers, storage tanks, offshore pipe piles and the like, and the large-folding straight transverse welding seams of hull plates and the like.

Fig. 3c is a schematic structural view of the limiting structure 12 in fig. 2 from a second viewing angle M according to some embodiments of the present application, wherein the welded test panel assembly 2 assembled in the limiting structure 12 is further shown. The specific structure of the position limiting structure 12 will be described in detail with reference to fig. 3a to 3 c.

As shown in fig. 3a, in some embodiments of the present application, the above-mentioned position limiting structure 12 includes a wale assembly 121, a front baffle 122 and a rear baffle 123. Wherein the front refers to the side close to the welding operation station, and the back refers to the side back to the operation station. For example, the front flap 122 is located on a side closer to the operation station than the rear flap 123. The wale assembly 121 is connected to the support structure 11 for limiting the longitudinal movement of the welding trial plate assembly 2. The front baffle 122 is disposed at the front of the limiting structure 12 and connected to the cross-brace assembly 121 for limiting the forward movement of the welding test panel assembly. The rear baffle 123 is disposed at the rear of the limiting structure 12 and connected to the cross brace assembly 121 for limiting the welding test panel assembly from moving backwards. The cross brace assembly 121, the front baffle 122 and the rear baffle 123 together form an accommodating cavity, and the operation channel is opened in the front baffle 122.

In the present embodiment, the front baffle 122 and the rear baffle 123 limit the welding test panel assembly 2 to move back and forth in the horizontal plane along the X-axis direction shown in fig. 2, and the wale assembly 121 prevents the welding test panel assembly 2 from falling down by gravity.

In order to facilitate the installation of the welding test panel assembly 2, in some embodiments of the present application, the two ends of the cross-brace assembly 121 along the direction of the Y axis shown in fig. 2 are respectively connected to the first longitudinal pillar 1121 and the second longitudinal pillar 1122, an installation channel for communicating the accommodating cavity with the outside is disposed at one end of the limiting structure 12 along the negative direction of the Y axis shown in fig. 2, and an insertion channel for communicating the installation channel with the outside is disposed at the second longitudinal pillar 1122, so as to prevent the second longitudinal pillar 1122 from blocking the welding test panel assembly 2 from being inserted into the installation channel.

In some embodiments of the present application, the width of the gap between the front baffle 122 and the rear baffle 123 (the lateral dimension of the gap, i.e., the dimension of the gap along the X-axis direction) is fixed, and is used for fixing the welding test panel assembly 2 with a certain width.

In order to stably fix the welding test plate assembly 2 in the accommodating space, the welding test plate assembly 2 in the accommodating cavity is controlled to be vertical so as to meet the requirement of welding the test plate assembly 2 vertically during transverse welding. In some embodiments of the present application, as shown in fig. 3b, the tooling device 1 further includes a fastening structure 13, and the fastening structure 13 is used for fastening the welding test panel assembly 2 to the limiting structure 12.

In some embodiments of the present application, as shown in fig. 3b, the abutting structure 13 includes a fixed wedge, a small end of the fixed wedge is embedded into a gap between the limiting structure 12 and the welding test panel assembly 2, and the small end abuts the outer surface of the welding test panel assembly 2 against the inner surface of the limiting structure 12.

In other embodiments of the present application, the fastening structure 13 is a bolt, specifically, a hole is formed in the limiting structure 12, and the bolt is installed to apply pressure to the welding test panel assembly 2 and fasten the welding test panel assembly 2 to the inner surface of the limiting structure 12 through the adjusting bolt. For example, holes are formed in the rear baffle 123 along the X-axis direction, the welding test panel assembly 2 is pressed and pressed against the front baffle 122 by the adjusting bolts, so as to vertically fix the welding test panel assembly 2, and the welding test panel assembly 2 is separated from the welding test panel assembly 2 by the adjusting bolts, so as to detach the welding test panel assembly 2.

The distance along the X axis in order to sandwich the gap between the front and rear shutters 122 and 123 can be adjusted as desired. In some embodiments of the present application, the distance between the front baffle 122 and the rear baffle 123 in the transverse direction (the X-axis direction shown in fig. 1) is adjusted by the distance adjusting device to clamp the welding test plate assemblies 2 with different thicknesses, so as to prevent the welding test plate assemblies 2 from moving forward and backward during the welding process, thereby reducing the welding quality.

For example, a distance adjusting apparatus using a bench vice is applied to the present embodiment, and specifically, the bench vice is structured by a vice body, a distance adjusting apparatus, and the like. The front baffle 122 adopts a movable caliper body, the rear baffle 123 adopts a fixed caliper body, and the front baffle 122 is in sliding fit with the guide rail of the rear baffle 123 through the guide rail. The spacing adjustment device uses a screw rod and nut combination, wherein the screw rod is mounted on the front baffle 122 and can rotate but cannot move axially, and the nut is mounted on the rear baffle 123. When the screw rod is rotated, the front baffle 122 can be driven to move axially relative to the rear baffle 123, so as to clamp or loosen the welding test plate assembly 2. The specific structure of the above distance adjusting means is merely described as an example, and is not intended to limit the structure of the present embodiment.

To facilitate the placement of the handling channel on the limiting structure 12 while limiting the forward movement of the welding trial assembly 2, in some embodiments of the present application, as shown in fig. 3a, the wale assembly 121 includes a lower beam 1211 and an upper beam 1212, and the front barrier 122 includes a lower barrier 1221 and an upper barrier 1222. The lower cross member 1211 is disposed on the support structure 11 and the lower baffle 1221 is attached to the lower cross member 121. The upper beam 1212 is connected to the lower beam 1211 through the tailgate 123, and the upper panel 1222 is connected to the upper beam 1212. The upper baffle 1222 and the lower baffle 1221 together form an operation channel. Specifically, the operation channel is shown in fig. 3c, and the operation channel is a longitudinal gap between the upper baffle 1222 and the lower baffle 1221 indicated by arrow P, and the upper and lower surfaces of the longitudinal gap are shown by dotted lines in fig. 3 c.

In the present embodiment, as shown in fig. 3a, the top surface of the backplate 123 is fixed to the upper cross member 1212, and the bottom surface of the backplate 123 is fixed to the lower cross member 1211, so that the upper cross member 1212 transmits the force on the backplate 123 to the first longitudinal pillars 1121 and the second longitudinal pillars 1122 to reinforce the backplate 123 and prevent the backplate 123 from being inclined backward (in the negative X-axis direction shown in fig. 1) when the welded seam on the welded test panel assembly 2 contracts and deforms. The upper stopper 1222 restricts forward (in the X-axis direction shown in fig. 1) movement of the upper portion of the welding test panel assembly 2. The lower stopper 1221 serves to restrict forward movement of the lower portion of the welding test panel assembly 2. An operating channel is formed between the lower surface of the upper barrier 1222 and the upper surface of the lower barrier 1221.

In some embodiments of the present application, as shown in fig. 3a, an upper cross beam 1212 is connected to the support structure 11, the upper cross beam 1212 serving to limit the upward movement of the welding trial assembly 2. The lower beam 1211 is connected to the support structure 11, and the lower beam 1211 is used for limiting the downward movement of the welding test panel assembly 2.

To facilitate mounting of the upper and lower beams 1211, 1211 and 1211, in some embodiments of the present application, the lower and upper beams 1211 and 1212 are connected to first and second longitudinal posts 1121 and 1122, respectively, at opposite ends in the direction along the Y-axis shown in fig. 2.

The heights and widths of the lower baffle 1221, the upper baffle 1222 and the rear baffle 123 can be adjusted as required, and the number of the lower baffle 1221 and the rear baffle 123 can be multiple, and is not limited to the number shown in the figures, so as to avoid the welding test panel assembly 2 from turning up and down (in the Z-axis direction shown in fig. 1) and back and forth (in the X-axis direction shown in fig. 1) when the welding test panel assembly 2 is installed, avoid the lower part of the welding test panel assembly 2 from being separated from the installation channel, and improve the efficiency and safety of dismounting and mounting the welding test panel assembly 2. The manner and effect of structural adjustment of the lower baffle 1221, the upper baffle 1222 and the rear baffle 123 described above will be specifically described below by way of example.

In order to avoid that the left and right ends of the welding test plate assembly 2 are turned backwards when the welding test plate assembly 2 is installed, and the left and right ends of the welding test plate assembly 2 are moved backwards when the welding test plate assembly 2 is welded, in some embodiments of the present application, as shown in fig. 3a, in some embodiments of the present application, the number of the back baffle 123 is three, and the back baffle 123 includes a first side back baffle 1231 disposed at the left portion of the lower beam 1211, a middle back baffle 1232 at the middle portion of the lower beam 1211, and a second side back baffle 1233 at the right portion of the lower beam 1211, respectively, so as to limit the left, middle, and right portions of the welding test plate assembly 2 from moving backwards.

In order to avoid that the left and right ends of the welding test plate assembly 2 are turned over forward when the welding test plate assembly 2 is installed, and the lower portions of the left and right ends of the welding test plate assembly 2 move forward when the welding test plate assembly 2 is welded, in some embodiments of the present application, as shown in fig. 3c, the number of the lower baffles 1221 and the upper baffles 1222 in the limiting structure 12 is at least two, and 2 lower baffles 1221 are respectively disposed at the left portion and the right portion of the lower beam 1211 to limit the forward movement of the left lower portion and the right lower portion of the welding test plate assembly 2. 2 upper baffles 1222 are respectively provided at left and right portions of the upper cross member 1212 to restrict the left and right upper portions of the welding test panel assembly 2 from moving forward. Here, in the present embodiment and hereinafter, the negative direction along the Y axis is left, the positive direction along the Y axis is right, the positive direction along the X axis is front, and the negative direction along the X axis is rear.

So, through above-mentioned embodiment, when having prevented installation welding test panel subassembly 2, the upset around welding test panel subassembly 2 improves the efficiency of installation welding test panel subassembly 2. Meanwhile, on the premise that the three rear baffles 123 guarantee that the welding test plate assembly 2 is limited to move, the width of the three rear baffles 123 is narrow, and the operating space for pushing the welding test plate assembly 2 when the welding test plate assembly 2 is dismounted and mounted by an operator is increased.
