[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] Please refer to Figure 1-Figure 6 The utility model discloses a welding positioning tool for a vertical plate assembly of a forklift, wherein the vertical plate assembly 400 has a first end and a second end opposite to each other, and two side plates 410 respectively located on opposite sides, and the welding positioning tool comprises:

[0035] A mounting plate 500, on which the vertical plate assembly 400 is placed;

[0036] A first positioning assembly 100, which is disposed on the mounting plate 500, and includes a first positioning block 110 and a second positioning block 120 respectively disposed at both ends of the vertical plate assembly 400, the first positioning block 110 being fixedly connected to the mounting plate 500, and the first positioning block 110 can abut against the first end; the second positioning block 120 can move relative to the mounting plate 500 in a direction toward or away from the vertical plate assembly 400, so as to abut against or separate from the second end;

[0037] The second positioning assembly 200 is arranged on the mounting plate 500, and the second positioning assembly 200 includes: a plurality of third positioning blocks 210 arranged on the opposite side of the vertical plate assembly 400, and the third positioning blocks 210 can move relative to the mounting frame in a direction toward or away from the vertical plate assembly 400 so as to abut against or separate from the side plate 410.

[0038] Specifically, the plurality of plates of the vertical plate assembly 400 are placed on the mounting plate 500, and then the first positioning block 110 in the first positioning assembly 100 is abutted against the plate at the first end, and then the second positioning block 120 is slid onto the plate at the second end to achieve positioning of the plates at both ends of the vertical plate assembly 400; at the same time, the plurality of third positioning blocks 210 in the second positioning assembly 200 abut against and position the two side plates 410 at the same time. In this way, the positioning of the plurality of plates of the entire vertical plate assembly 400 can be achieved through the first positioning assembly 100 and the second positioning assembly 200, so that the positioning between the plurality of plates is more accurate and the welding is more reliable.

[0039] Furthermore, the third positioning block 210 is located outside the side plate 410 and can abut against the outer wall of the side plate 410;

[0040] A plurality of support blocks 240 are further disposed on the inner side of the side plate 410 , and the support blocks 240 can abut against the inner wall of the side plate 410 .

[0041] Specifically, the third positioning block 210 is in contact with the outer side of the side plate 410, and the support block 240 is arranged at the inner side of the side plate 410, so that force can be applied to both the inner and outer sides of the side plate 410 at the same time to prevent the side plate 410 from bending and deformation, while improving the positioning accuracy.

[0042] Furthermore, a tightening cylinder 220 and a rotatable tightening rod 230 are also provided on the third positioning block 210. The tightening rod 230 is connected to the tightening cylinder 220. The tightening rod 230 can be rotated to the side of the side plate 410 away from the third positioning block 210. The contraction of the tightening cylinder 220 can drive the tightening rod 230 to abut against the side of the side plate 410 away from the third positioning block 210.

[0043] Specifically, a tightening cylinder 220 is arranged on the side of the third positioning block 210, and a tightening rod 230 is arranged on the tightening cylinder 220. When the third positioning block 210 moves toward the side plate 410 until the tightening rod 230 passes over the side plate 410, the third positioning block 210 abuts against the outer side of the side plate 410. At this time, the tightening rod 230 rotates to the inner side of the side plate 410, and then the tightening cylinder 220 pulls the tightening rod 230 outward to make the tightening rod 230 abut against the inner side of the side plate 410. In this way, the tightening rod 230 and the third positioning block 210 abut against the inner and outer sides of the same position on the side plate 410, respectively, thereby improving the positioning accuracy.

[0044] It should be noted that a driving motor can be provided to drive the tightening cylinder 220 to rotate, thereby causing the tightening rod 230 to rotate together with the tightening cylinder 220. A driving motor can also be provided between the tightening cylinder 220 and the tightening rod 230 to achieve the independent rotation of the tightening rod 230.

[0045] Furthermore, a layer plate 420 is provided at the first end;

[0046] It also includes a third positioning assembly 300, which includes a column 310, and the column 310 is fixedly set on the mounting plate 500. The column 310 is provided with an abutment column 320 and a tensioning block 340. The abutment column 320 is fixedly set on the column 310 and can abut against one side of the layer plate 420, and the tensioning block 340 is rotatably connected to the column 310 and can abut against the other side of the layer plate 420.

[0047] Specifically, the abutting column 320 in the third positioning assembly 300 abuts against one side of the layer plate 420, and then the tensioning block 340 is rotated so that the tensioning block 340 abuts against the other side of the layer plate 420 and abuts against both sides of the layer plate 420, thereby achieving precise positioning of the layer plate 420.

[0048] Furthermore, a rotating cylinder 330 is disposed on the column 310 for driving the tension block 340 to rotate.

[0049] Furthermore, a detection block 430 is provided on the layer plate 420, and a detection hole 431 is provided on the detection block 430;

[0050] It also includes a detection seat 440 and a detection rod 450 . The detection rod 450 is slidably disposed on the detection seat 440 . The detection seat 440 is disposed on the mounting plate 500 . The detection rod 450 can slide relative to the detection seat 440 to extend into the detection hole 431 .

[0051] Specifically, since the detection seat 440 is fixedly arranged on the mounting plate 500, the position of the detection seat 440 is determined. If the position of the layer plate 420 is installed correctly, the detection rod 450 on the detection seat 440 can be aligned with the detection hole 431 and smoothly extend into the detection hole 431; if the position of the layer plate 420 is installed incorrectly, the detection rod 450 on the detection seat 440 cannot extend into the detection hole 431. In this way, the position of the layer plate 420 can be detected, so that the layer plate 420 can be adjusted to the correct position before welding.

[0052] Furthermore, the first positioning assembly 100 also includes a first driving cylinder, and the second positioning block 120 is connected to the telescopic rod of the first driving cylinder.

[0053] Furthermore, the second positioning assembly 200 also includes a second driving cylinder, and the third positioning block 210 is connected to the telescopic rod of the second driving cylinder.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
