[0044] Preferably, Figure 3-4 As shown, the base 1 includes a base bottom plate 11 and a connecting plate 12;

[0045] The bottom surface of the base is the bottom surface of the base bottom plate 11;

[0046] The connecting plate 12 is fixedly arranged on the top surface of the base bottom plate 11 , and the angle disc 16 is engraved on the upper part of the connecting plate 12 .

[0047] Specifically, the base bottom plate 11 has a length of 400 mm, a width of 200 mm, and a height of 20 mm; the connecting plate 12 is located at the center of the base bottom plate 11 in the width direction;

[0048] The vertical distance between the center of the angle disc 16 and the top surface of the base bottom plate 11 is 180 mm, and the radius of the angle disc 16 is 100 mm;

[0049] The diameter of the base connection hole 15 is 10 mm.

[0050] Preferably, the scales of the angle lines on the angle disk 16 gradually increase from the middle position to both sides, that is, the zero scale line is located in the middle position of the semicircular structure, and the scales of the other angle lines gradually increase from the middle position to both sides.

[0051] Preferably, the zero scale line on the angle disk 16 is perpendicular to the bottom surface 14 of the base.

[0052] Preferably, toggle plates 13 are symmetrically arranged between the two side surfaces of the connecting plate 12 and the base bottom plate 11 to play a role of fixing and strengthening.

[0053] Specifically, the toggle plate 13 is a right-angled triangular plate structure, the long right-angled sides of the toggle plate 13 are fixedly connected to the corresponding side surfaces of the connecting plate 12 , and the short right-angled sides are fixedly connected to the top surface of the base bottom plate 11 .

[0055] Preferably, the angle standard surface 231 is perpendicular to the bottom surface 21 of the rotating rod.

[0056] Preferably, the rotating connector is a bolt 3 passing through the base connecting hole 15 and the rotating rod connecting hole 22, and a nut 4 is provided at the end of the bolt 3. When installing the nut 4, an appropriate tightness should be maintained to ensure the rotational connection between the rotating rod 2 and the base 1.

[0057] The process of using the angle measurement device for welding deformation of the panels of the present application to measure the welding angle deformation between the first panel 5 and the second panel 6 is as follows:

[0058] Arrange the first puzzle board 5 and the second puzzle board 6 into the required connection orientation;

[0059] Before welding, Figure 6 As shown, the bottom surface 14 of the base is attached to the first puzzle board 5, and the bottom surface 21 of the rotating rod is attached to the second puzzle board 6. The scale a of the angle line aligned with the angle standard surface 231 is read and the direction in which the angle standard surface 231 deviates from the zero scale line is recorded; the scale a is the angle between the first puzzle board 5 and the second puzzle board 6 at this time;

[0060] Then, the first panel 5 and the second panel 6 are welded on the front side;

[0061] After the front welding, the bottom surface 14 of the base is again attached to the first puzzle plate 5, and the bottom surface 21 of the rotating rod is attached to the second puzzle plate 6.

[0062] When the directions of the angle standard surface 231 deviating from the zero scale line before and after welding are consistent, the value of |ab| is the angle value of the welding deformation during this welding process;

[0063] When the angle standard surface 231 deviates from the zero scale line in opposite directions before and after welding, the value of a+b is the angle value of the welding deformation during this welding process.

[0064] The principle of the angle line aligned with the angle standard surface 231 in the measuring device of the present application is as follows: Figure 7 As shown:

[0065] Figure 7 α1 is the angle between the first panel 5 and the second panel 6, and β1 is the scale of the angle line to which the angle standard surface 231 is aligned;

[0066] Since α1+α2=180°, α2+β2=180°, therefore, α1=β2;

[0067] And since β1=β2, therefore α1=β1.

[0068] That is, the scale of the angle line to which the angle standard surface 231 is aligned is the angle between the first puzzle board 5 and the second puzzle board 6 .

[0069] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not a limitation of the present invention.
