Description

Technical Field

[0001] The present application relates to the field of door panel welding, and in particular to a left door panel ring welding tool. Background Art

[0002] Door panel welding is a steel structure welding technique commonly used in the production of metal doors, window frames, automotive parts, and other industries. This technique involves welding multiple thin plates into a single unit, ensuring strength while reducing steel usage and thus lowering production costs. There are two methods for door panel welding: manual welding and machine welding. Manual welding requires the welder to manually adjust the arc to control welding quality and speed, and is generally suitable for lower-cost applications. Machine welding, on the other hand, uses automated welding equipment, significantly improving production efficiency and quality, and is suitable for producing a large number of products of varying sizes.

[0003] Currently, when door panels are welded, the welded door panels need to be assembled first. During the assembly process or the welding process, vibration may occur between the door panels, which may cause misalignment of the joints of the door panels during welding, which is not conducive to improving the overall welding effect.

[0026] The embodiment of the present application discloses a left door panel ring welding tool, including a base 1, a processing table 2 is installed on the base 1, and a pad 16 is movably installed on the upper part of the processing table 2. There are multiple pads 16, and multiple pads 16 are provided with A pieces 5, B pieces 6, C pieces 7, D pieces 8 and E pieces 9. A first positioning magnet 10 is provided on the pad 16 at the connection between the A piece 5 and the B piece 6, and a second positioning magnet 11 is provided at the lower part of the connection between the B piece 6 and the C piece 7. The B piece 6 is positioned and fixed by magnetic attraction by the first positioning magnet 10 and the second positioning magnet 11. A third positioning magnet 12 is provided at the lower part of the connection between the C piece 7 and the D piece 8. The two pieces of material, A piece 5 and D piece 8, are fixed by magnetic attraction by the first positioning magnet 10 and the third positioning magnet 12. The lower part of the connection between the D piece 8 and the E piece 9 is provided with a It is equipped with a fourth positioning magnet 13, and a fifth positioning magnet 14 is installed at the lower part of the connection between the E piece 9 and the A piece 5. The E piece 9 and the C piece 7 are magnetically fixed by the second positioning magnet 11 and the fifth positioning magnet 14. A driving cylinder 15 is installed on the processing table 2. The processing table 2 is movably connected with the pad 16 through the driving cylinder 15. The output end of the driving cylinder 15 is connected to the lower part of the pad 16. There are three driving cylinders 15. The three driving cylinders 15 are respectively located at the lower part of the B piece 6, the D piece 8 and the E piece 9. The three driving cylinders 15 can drive the B piece 6, the D piece 8 and the pad 16 at the lower part of the E piece 9 to move. The driving cylinder 15 drives the pad 16 to pull the gap, and the pad 16 drives the three pieces of material to move. The operator can actually pull the gap according to the 6 welds, make high-precision adjustments and lock them.

[0027] A nut 3 is installed on the processing table 2, and a threaded pressure rod 4 is threadedly connected to the nut 3. There are multiple threaded pressure rods 4, which pass through the B piece 6, the D piece 8 and the E piece 9 respectively. Through holes are opened on the B piece 6, the D piece 8 and the E piece 9. The diameter of the threaded pressure rod 4 is adapted to the diameter of the through hole. The threaded pressure rod 4 is connected to the nut 3 at the bottom through the through hole. The nut 3 and the threaded pressure rod 4 are mechanical auxiliary positioning points, which are used to assist the six pieces of material to be more stable when positioning.

[0028] The end faces of piece A 5 , piece B 6 , piece C 7 , piece D 8 and piece E 9 are flush and spliced ​​to each other, and a gap of 0.3 mm is left at the splicing. By flushing the end faces, the six pieces of material can be effectively welded.

[0029] The implementation principle of a left door panel ring welding tooling in an embodiment of the present application is as follows: the left and right door ring parts have the same material specifications, are both welded from 5 pieces of material, and are arranged symmetrically on the left and right. The 5 pieces of material correspond to piece A 5, piece B 6, piece C 7, piece D 8 and piece E 9. The tooling needs to accurately position piece A 5, piece B 6, piece C 7, piece D 8 and piece E 9 to prepare for the next welding step. The materials are positioned by weld alignment splicing. After positioning, the five welds are pulled out with a gap of 0.3mm at a certain angle, and reliable repeated positioning accuracy is guaranteed. During the welding process, the weld collection amount is guaranteed to be no more than 0.1mm.

[0030] First, splice the two pieces of material A 5 and D 8, and after positioning, use the first positioning magnet 10 and the third positioning magnet 12 to magnetically fix the two pieces of material A 5 and D 8. Use the welds of the two pieces of material A 5 and D 8 as a backing, and a small number of mechanical auxiliary positioning points to place the two pieces of material E 9 and C 7. After positioning, use the second positioning magnet 11 and the fifth positioning magnet 14 to magnetically fix them. Finally, use the welds of the two pieces of material A 5 and C 7 as a backing to place the B piece 6. Use the first positioning magnet 10 and the second positioning magnet 11 to position and then magnetically fix them. Manually confirm whether the weld splicing meets the production requirements. At the same time, confirm whether it is necessary to adjust the positioning device and mechanical auxiliary positioning points based on the splicing results.

[0031] The PLC system receives manual confirmation of the completion of material splicing instructions, and then starts to execute the gap pulling process. According to the 3D diagram fitting, the PLC system and the 3D diagram fitting are existing technologies and are not shown in the figure. They will not be described here. The three pieces of material, E piece 9, D piece 8 and B piece 6, are pulled to finally achieve a 0.3mm gap (plus or minus 0.05mm) between the 6 welds of the three pieces of material. The gap is pulled by the driving cylinder 15 to drive the pad 16, and the pad 16 drives the three pieces of material to move. The operator can make high-precision adjustments and locks according to the actual pulling gap of the 6 welds to ensure the repeatability of subsequent splicing. After manual inspection and confirmation, enter the welding machine for welding.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
