[0002] At present, intermittent welding of structural parts is a common connection method. Compared with full continuous welding, intermittent welding has the advantages of saving materials, reducing production costs, and avoiding welding deformation caused by continuous welding. Therefore, it is widely used in the field of metal processing. The spacing and weld length of intermittent welding have a crucial impact on the quality of assembly welding. If the spacing and weld length are not set properly at the butt joint path, it will not only cause welding deformation, stress concentration and other problems, but also cause welding defects. Therefore, the specification requirements for intermittent welding are also very important.

[0003] In the prior art, since there is no professional intermittent weld marking device, especially for intermittent welding at the butt joint of welded parts, where the path is long, the path is diverse, and the welding position is staggered, the existing manual marking is done by visually marking with a steel tape measure, which makes it difficult to ensure the consistency of the weld spacing. The marking process is complicated, the work intensity is high, the operation steps are cumbersome, the marking accuracy is low, and the production efficiency is also affected. Therefore, it is very necessary to design a simple, easy-to-operate, and more accurate universal device for riveting intermittent weld marking. Summary of the invention

It is easy and quick to operate, has strong measurement stability, and effectively reduces the operating error caused by the traditional method of visually marking with a steel ruler.

[0020] (2) This manufacturing method uses a continuous marking device to complete the continuous marking of the weld position. The continuous marking device is easy to move along the straight line surface or curved surface path trajectory of the welded part through the mobile bracket assembly, and can complete continuous marking on straight lines, curves, wavy lines, circles and other path trajectories.

On the butt welding path line of the assembly welded parts, marking can be performed cyclically and continuously. For the marking of batch parts, as long as the size correction work of the first piece is completed, the subsequent repeated operations can be performed, which greatly reduces the labor intensity of the marking personnel and improves the production efficiency. The marking accuracy is guaranteed by the tooling;

Therefore, the segment weld interval marking device is relatively simple in structure and can meet the needs of different operational technical requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0067] In order to explain the present invention in more detail, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0068] Example 1

[0069] This embodiment provides a method for manufacturing an intermittent weld marking device, such as Figure 5 As shown, this embodiment is described by the intermittent welding connection between the rectangular tube and the steel plate 5. The specific specifications of the two groups of weldments are: the rectangular steel tube 4 is 250mm*150mm*6mm in size and 5000mm in length, and the steel plate 5 is 80mm*16mm in size and 5000mm in length. The welding process requires the weld length to be 60mm, the weld interval to be 160mm, the fillet weld height to be 6mm, and the butt joint between the steel plate 5 and the steel tube 4 to be a straight welding path.

[0070] This embodiment includes the following steps:

[0071] Step 1: Combine Figure 1 to Figure 2 as well as Figure 6 to Figure 7As shown, the movable bracket assembly 10 in the continuous marking device 1 is in close contact with the straight surface of the steel pipe 4. Specifically, the rotating movable sleeve 101 in the movable bracket assembly 10 is used to slide along the side of the steel pipe 4 to roughly adjust the height position of the telescopic support rod 11 supported by the top of the vertical rod 12. Specifically, the vertical rod 12 is pulled up and down on the open support 100 in the movable bracket assembly 10 for vertical sliding adjustment. After the adjustment is completed, it is locked by the locking bolt 13. The vertical height position of the telescopic support rod 11 is roughly adjusted to ensure that the marking position meets the requirements. The rod sleeve 121 is slidably adjusted transversely along the rod sleeve 121 so that the marking needle rod 17 can be moved transversely to the marking position, wherein the marking needle rod 17 can be adjusted in height and angle at the end of the telescopic support rod 11 by locking the round seat 15, so that the marking needle rod 17 is adjusted to operate at the corresponding weld position, and a slight external force is applied to the telescopic support rod 11 to form a sliding friction fit between the bottom end of the marking needle rod 17 and the surface of the material to be marked, and under the action of the moving bracket assembly 10 moving along the straight surface path trajectory of the steel pipe 4, continuous marking marks are completed at the weld position between the parts to be welded.

[0072] Step 2: Combine Figure 3 to Figure 4 as well as Figures 8 to 9 As shown, when the segment weld interval marking device 2 is adjusted, the four marking rods 20 included in the segment weld interval marking device 2 are the ends of a parallelogram structure, wherein the gap distance between the two marking rods 20 on one side line is 60 mm of weld length, and the gap distance between the two marking rods 20 on the other side line is 160 mm of weld segment interval length. During operation, the two marking rods 20 with a weld length of 60 mm correspond to the continuous marking marks of the weld position formed in step 1, and the segment weld interval marking device 2 is repeatedly rotated clockwise until the interval marking of the entire length of 5000 mm of the welding path is completed, thereby marking the continuous marking marks of the weld position at intervals and cross positions.

[0073] Step 3: Combine Fig.10 As shown, according to the marking traces of the interval intersection position in step 2, use the right angle side of the square ruler 40 to coincide with the interval intersection position marking, use a stone pencil to mark the line segments, repeat in sequence, complete the weld length and the weld segment interval length to mark the position line.

[0074] Example 2

[0075] This embodiment provides a method for manufacturing an intermittent weld marking device, such as Fig.11As shown, this embodiment is described by the discontinuous welding connection between the steel plate 2 6 and the circular steel plate 7. The specific specifications of the two sets of weldments are: the square steel plate 2 6 is 2000mm*2000mm*20mm, the outer diameter of the circular steel plate 7 is Φ1600mm, the inner diameter is Φ1400mm, and the height is 16mm. The welding process requires that the weld length is 60mm, the weld interval is 120mm, the fillet weld height is 6mm, and the butt connection between the steel plate 2 6 and the circular steel plate 7 is a circumferential welding path.

[0076] This embodiment includes the following steps:

[0077] Step 1: Combine Figure 1 to Figure 2 as well as Figure 12 to Figure 13 As shown, the movable bracket assembly 10 in the continuous marking device 1 is in close contact with the outer peripheral curved surface of the circular steel plate 7. Specifically, the rotating movable sleeve 101 in the movable bracket assembly 10 is used to slide along the outer peripheral curved surface of the circular steel plate 7 to roughly adjust the height position of the telescopic support rod 11 supported by the top of the vertical rod 12. Specifically, the vertical rod 12 is pulled up and down on the open support 100 in the movable bracket assembly 10 for vertical sliding adjustment. After the adjustment is completed, it is locked by the locking bolt 13. The vertical height position of the telescopic support rod 11 is roughly adjusted to ensure that the marking position meets the requirements. The rod 11 is slidably adjusted transversely along the rod sleeve 121 so that the marking needle rod 17 can be moved transversely to the marking position, wherein the marking needle rod 17 can be adjusted in height and angle at the end of the telescopic support rod 11 by locking the round seat 15, so that the marking needle rod 17 is adjusted to operate at the corresponding weld position, and a slight external force is applied to the telescopic support rod 11 to form a sliding friction fit between the bottom end of the marking needle rod 17 and the surface of the material to be marked, and under the action of the moving bracket assembly 10 moving along the outer peripheral curved surface path trajectory of the circular steel plate 7, continuous marking marks are completed at the weld position between the parts to be welded.

[0078] Step 2: Combine Figure 3 to Figure 4 as well as Figure 14 to Figure 15 As shown, when the segment weld interval marking device 2 is adjusted, the four marking rods 20 included in the segment weld interval marking device 2 are the ends of a parallelogram structure, wherein the gap distance between the two marking rods 20 on one side line is 60 mm of the weld length, and the gap distance between the two marking rods 20 on the other side line is 120 mm of the weld segment interval length. During operation, the two marking rods 20 with a weld length of 60 mm correspond to the continuous marking marks of the weld position formed in step 1, and the segment weld interval marking device 2 is repeatedly rotated clockwise until the interval marking on the continuous curved path mark is completed, thereby marking the continuous marking marks of the weld position at intervals and crossing positions.

[0079] Step 3: Combine Figures 16 to 18As shown, according to the marking marks of the interval crossing positions in step 2, the continuous marking device 23 is used to complete the weld length and the weld segment interval length to mark the position line. The continuous marking device 23 has the same structure and shape as the continuous marking device 1. Specifically, the mobile bracket assembly 230, the rod sleeve part 2310 and the telescopic support rod 232 included in the continuous marking device 1 are respectively consistent with the corresponding structural shapes of the mobile bracket assembly 10, the rod sleeve part 121 and the telescopic support rod 11 included in the continuous marking device 1. Similarly, the vertical adjustment height between the mobile bracket assembly 230 and the vertical pole 231 is locked by the locking bolt 533, and the horizontal adjustment length between the telescopic support rod 232 and the rod sleeve part 2310 is locked by the locking bolt 634. The height of the vertical pole 231 included in the different continuous marking devices 23 is much smaller than the height of the vertical pole 12 included in the continuous marking device 1.

[0080] When the continuous marking device 23 is operating to mark the position line, the mobile bracket assembly 230 in the continuous marking device 2 is close to the outer peripheral curve surface of the circular steel plate 7, and then the vertical height of the vertical rod 231 and the lateral extension position of the telescopic support rod 232 are adjusted. Under the action of the mobile bracket assembly 10 moving along the path trajectory of the outer peripheral curve surface of the circular steel plate 7, the telescopic support rod 232 is coincident with the marking line of the interval intersection position, and the line segment is marked with a stone pencil. Repeat this process in sequence to complete the weld length and the weld segment interval length to mark the position line.

[0082] This embodiment provides a method for manufacturing an intermittent weld marking device, such as Fig.19 As shown, this embodiment is explained by the intermittent welding connection between steel plate three 8 and steel plate four 9. The specific specifications of the two groups of weldments are: the specifications of steel plate three 8 are 6000mm*120mm*16mm, and the specifications of steel plate four 9 are 5000mm*80mm*16mm. The welding process requires the weld length to be 80mm, the weld interval to be 300mm, the weld height of the fillet weld to be 6mm, and the butt joint position of steel plate three 8 and steel plate four 9 is a straight welding path, but the weld length or interval length in the butt joint path of the combined weldment is greater than the maximum adjustable distance that the adjustment plate one 21 and the adjustment plate two 22 in the segment weld interval marking device 2 can adjust. At this time, compared with embodiment 1, the difference is that step 2 performs the adjustment of the different segment weld interval marking devices 2.

[0083] Combination Figure 20 to Figure 22As shown, when the segment weld interval marking device 2 in step 2 of this embodiment is adjusted, the four marking rods 20 included in the weld interval marking device are the ends of an irregular quadrilateral structure, wherein three marking rods 20 are the ends of an isosceles triangle structure, the gap distance between the two marking rods 20 on the bottom line is the weld length, and the gap distance between the two marking rods 20 on the waist line is half of the weld segment interval length. The specific operation is to mark the four marking rods 20 as No. 1, No. 2, No. 3 and No. 4, respectively, and adjust the gap distance between the No. 1 and No. 2 marking rods 20 to a weld size of 80mm, since the weld interval size of 300mm is larger than the maximum adjustable distance that the adjusting plate 1 21 and the adjusting plate 2 22 can adjust, the method of taking the median of the weld interval size of 300mm is adopted in the drawing method. Therefore, the gap distance between the No. 2 and No. 3 marking needle rods 20 is adjusted to 150mm, and the gap distance between the No. 3 and No. 1 marking needle rods 20 is also 150mm, so as to realize the clockwise reciprocating operation of the segment weld interval marking device 2 until the interval marking of the entire length of 5000mm of the welding path is completed, so that the continuous marking marks at the weld position are marked at intervals and cross positions.

All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
