Description

Technical Field

[0001] The invention belongs to the technical field of welding, and specifically relates to a positioning welding device for sheet metal parts of new energy vehicles. Background Art

[0002] New energy vehicle sheet metal parts refer to the metal sheet parts used to form the body appearance and structure of new energy vehicles, mainly including body covering parts such as roof, doors, engine hood, trunk lid, and body structural parts such as longitudinal beams, cross beams, etc. In the production process of new energy vehicles, it is usually necessary to weld two sheet metal parts into one to meet different structural requirements. In addition, in order to ensure that the two sheet metal parts can be welded accurately, the two sheet metal parts are generally positioned first and then welded.

[0003] The patent with announcement number CN218284074U discloses a new energy vehicle sheet metal positioning welding device. Provided is a new energy vehicle sheet metal positioning welding device that can automatically drive the electric welder to move and ensure the welding efficiency of sheet metal parts. A new energy vehicle sheet metal positioning welding device, a guide frame, a support frame, a connecting shaft, a gear, a first rack and a second rack, etc., the front and rear sides of the right side of the top of the guide frame are connected to the support frame, and the front and rear sides of the left side of the bottom of the guide frame are also connected to the support frame. The front and rear sides of the middle of the guide frame are rotatably connected to the connecting shaft, and the two connecting shafts are connected to gears. The first rack is slidably connected to the right side of the guide frame, and the first rack is meshed with the gear on the same side. The second rack is slidably connected to the left side of the guide frame. This patent is provided with an electric slide rail and an electric slider, which can quickly weld sheet metal parts.

[0004] However, the above technical solution still has the following deficiencies in practical application:

[0005] When multiple sheet metal parts need to be welded at one time, in order to ensure the consistency of welding quality, the staff is required to compare and check the weld quality of multiple welded sheet metal parts. Because in the production of new energy vehicles, the consistency requirements for parts and components are very high. By comparing and checking the welds of multiple sheet metal parts, sheet metal parts with welding defects can be discovered in time, and repair welding can be performed in time to ensure that the weld quality of the sheet metal parts remains consistent, thereby improving the overall consistency of the product. When the staff compare and check the weld quality of multiple welded sheet metal parts, the multiple sheet metal parts may be placed in a messy manner, and it is not easy to make a unified comparison of the welds of multiple sheet metal parts, and even confusion may occur, affecting the subsequent repair welding work.

[0048] Specifically, new energy vehicle sheet metal parts refer to the metal sheet parts used to form the appearance and structure of the body of new energy vehicles, mainly including body covering parts such as roofs, doors, engine hoods, trunk lids, and body structural parts such as longitudinal beams, cross beams, etc. In the production process of new energy vehicles, it is usually necessary to weld two sheet metal parts into one to meet different structural requirements, and in order to accurately weld the two sheet metal parts, the two sheet metal parts are generally positioned first, and then welded; during the use of existing new energy vehicle sheet metal positioning welding devices, when it is necessary to weld multiple sheet metal parts at one time, in order to ensure the consistency of welding quality, the staff needs to weld multiple welded sheet metal parts. The weld quality is compared and checked, because in the production of new energy vehicles, the consistency requirements for parts are very high. By comparing and checking the welds of multiple sheet metal parts, sheet metal parts with welding defects can be found in time, and repair welding can be carried out in time to ensure that the weld quality of sheet metal parts is consistent, thereby improving the overall consistency of the product. When the staff compares and checks the weld quality of multiple welded sheet metal parts, the multiple sheet metal parts may be placed in a messy manner, and it is not easy to uniformly observe the welds of multiple sheet metal parts, and even confusion may occur, which affects the subsequent repair welding work. In addition, it is also troublesome for the staff to manually organize the sheet metal parts, which increases the labor intensity of the staff;

[0049] Therefore, in order to solve the above problem, this embodiment is used for the same batch of sheet metal parts with the same specifications, and the angle of one side of the sheet metal part is 45 degrees. The two sheet metal parts are welded to form a right-angle sheet metal part. The right-angle sheet metal part is a common geometric angle and has stability and reliability in the vehicle body structure design.

[0050] When the two sheet metal parts are fixed and the angles are mutually fitted at the angle of the limit plate 2 16, the electric push rod 1 4 is used to drive the slide plate 5 to move so that the welding gun 9 is at the end of the gap where the limit plate 2 16 fits, and then the motor 1 6 is used to drive the threaded rod 2 8 to rotate so that the welding gun 9 is lowered to a suitable position, and then the welding gun 9 is turned on, and the electric push rod 1 4 is used to drive the welding gun 9 to move, and welding can be carried out until the two sheet metal parts are welded into one. When the two sheet metal parts are welded into one, the welding gun 9 is driven to move away from the top of the sheet metal parts, and then the motor 7 42 is used to drive the threaded rod 8 41 to rotate so that the fastening rod 11 slides upward, which can drive the sheet metal parts to rise. When the lower end surface of the sheet metal part is higher than the upper end surface of the slide plate 38, the motor 7 42 is used to drive the threaded rod 8 41 to rotate so that the fastening rod 11 slides upward, which can drive the sheet metal parts to rise. The motor 6 40 drives the threaded rod 7 39 to rotate, so that the slide plate 38 slides to the bottom of the sheet metal part. At this time, the positioning block 44 is driven away from the sheet metal part to release the sheet metal part. The sheet metal part falls on the slide plate 38 and is limited by the limiting plate 1 13 and the limiting plate 2 16. In addition, the motor 3 17 can be used to drive the threaded rod 4 19 to rotate according to the width of the sheet metal part, and the spacing between the limiting plate 13 and the limiting plate 2 16 can be adjusted to ensure that the angle of the limiting plate 13 can fit the angle of the sheet metal part. Then the positioning block 44 is lowered to the initial position to carry out the next welding. After the welding of the next sheet metal part is completed, the above-mentioned rising work is repeated, and the sheet metal part on the upper side falls on the sheet metal part on the lower side, so that multiple sheet metal parts can be neatly stacked.

[0051] When the sheet metal parts are placed to a sufficient number, according to the position of the gap between the two lowest sheet metal parts, the motor four 24 is used to drive the threaded rod five 25 to rotate, so that the adjustment plate 26 slides up and down, so that the paddle one 30 is aligned with the gap between the lowest sheet metal part and the slide plate 38, and then the motor five 35 is used to drive the threaded rod six 37 to rotate, so that the paddle two 31 rises and slides on the slide bar five 36, and with the cooperation of the connecting rod one 33 and the connecting rod two 34, multiple paddles three 32 move at the same time, and the spacing between the multiple paddles three 32 is always consistent and equal to the spacing between the paddle one 30, the paddle two 31 and the adjacent paddle three 32. Therefore, when any paddle three 32 is aligned with the gap between the two sheet metal parts, the remaining paddles three 32 are also aligned with the gap between the sheet metal parts. , and then use the electric push rod 3 27 to drive the mounting frame 29 to move, so that the paddle 1 30, the paddle 2 31, and the paddle 3 32 are simultaneously inserted into the gaps between the sheet metal parts, so that the multiple sheet metal parts can be separated, and then the paddle 2 31 is continuously driven to rise, so that the spacing between the multiple paddles 3 32 can be expanded, so that the weld is no longer covered. At this time, the staff can intuitively observe the welds of multiple sheet metal parts and conduct comparative inspections to help the staff determine whether repair welding is needed, thereby ensuring the consistency of welding, and the orientations of multiple sheet metal parts are relatively uniform, and the staff does not need to frequently move their bodies for observation, which is more convenient and less likely to cause confusion during inspection. It also saves the staff from manually sorting the sheet metal parts, saving manpower;

[0052] After the comparison and inspection work is completed, if the sheet metal part needs to be transported or repaired, the paddle 32 is driven away from the sheet metal part, and then the slide plate 38 is driven to slide, so that the bottom of the sheet metal part loses support, so that the sheet metal part can fall, and then it can be transported or repaired. In addition, a container can be placed under the sheet metal part to receive the sheet metal part, and then the subsequent transport work can be carried out;

[0053] When the number of sheet metal parts is large and heavy, if multiple sheet metal parts fall into the storage container at the same time, it may be difficult for the staff to lift them, which will cause difficulties in transportation. Therefore, according to the actual transportation capacity of the staff, the motor 2 15 can be used to drive the threaded rod 3 14 to rotate, so that the L-shaped block 22 can be raised and lowered, and the partition 23 can be aligned with the gap between the two sheet metal parts. Then, the electric push rod 20 can be used to drive the partition 23 to move and insert it into the gap, so that the multiple sheet metal parts can be divided into upper and lower parts. At this time, the slide plate 38 is driven away from the bottom of the sheet metal part, so that the sheet metal part under the partition 23 can fall into the container. At this time, the staff only needs to transport part of the sheet metal parts, which reduces the difficulty of single transportation work and reduces the labor intensity of the staff.

[0054] Therefore, with the cooperation of the lifting positioning mechanism and the separated stacking positioning mechanism, multiple welded sheet metal parts can be uniformly stacked in the same place and separated from each other, so that the staff can visually observe the welds of multiple sheet metal parts and compare and check the quality of the welds to help the staff determine whether repair welding is needed, thereby ensuring the consistency of welding, and the orientation of multiple sheet metal parts is relatively uniform, and the staff does not need to move their bodies frequently for observation, which is more convenient and less likely to cause confusion during inspection, and also saves the staff from the process of manually sorting the sheet metal parts, and when the welded sheet metal parts need to be transported , a container can be placed under the stacked sheet metal parts, and then, according to the actual handling capacity of the staff, the motor 2 15 can be used to drive the threaded rod 3 14 to rotate, so that the L-shaped block 22 can be raised and lowered, and the partition 23 can be aligned with the gap between the two sheet metal parts, and then the electric push rod 20 can be used to drive the partition 23 to move and insert it into the gap, so that the multiple sheet metal parts can be divided into two parts, upper and lower. At this time, the slide plate 38 is driven away from the bottom of the sheet metal parts, so that the sheet metal parts under the partition 23 can fall into the container. At this time, the staff only needs to transfer part of the sheet metal parts, which reduces the difficulty of a single transfer and reduces the labor intensity of the staff.

[0055] Working principle: manually fit the 45-degree angle of the two sheet metal parts to be welded into one piece together, and make them against the inner angle of the limit plate 2 16, and place one side of the sheet metal part at the angle on the upper side of the fastening rod 11, then start the motor 8 43 to drive the threaded rod 1 7 to rotate, so that the positioning block 44 slides on the threaded rod 1 7 and the sliding rod 6 45, and approaches the sheet metal part until it fits with the edge of the sheet metal part, so that the sheet metal part can be clamped and fixed, thereby ensuring the stability of the sheet metal part during welding, and use the electric push rod 1 4 to drive the slide plate 5 to move, so that the welding gun 9 is at the end of the gap at the fitting place of the limit plate 2 16, and then use the motor 1 6 to drive the threaded rod 2 8 to rotate, so that the welding gun 9 is lowered to the appropriate position, and then turn on the welding gun 9, and then use the electric push rod 1 4 to drive the welding gun 9 to move, and welding can be carried out until the two sheet metal parts are welded into one piece. When the two sheet metal parts are welded into one piece, drive the welding gun 9 to move away from the top of the sheet metal part. Then, the motor 7 42 is used to drive the threaded rod 8 41 to rotate, so that the fastening rod 11 slides upward, and the sheet metal part can be driven to rise. When the lower end surface of the sheet metal part is higher than the upper end surface of the slide plate 38, the motor 6 40 is used to drive the threaded rod 7 39 to rotate, so that the slide plate 38 slides under the sheet metal part. At this time, the positioning block 44 is driven away from the sheet metal part to release the sheet metal part, and the sheet metal part falls on the slide plate 38 and is limited by the limit plate 1 13 and the limit plate 2 16. In addition, according to the width of the sheet metal part, the motor 3 17 can be used to drive the threaded rod 4 19 to rotate, and the spacing between the limit plate 1 13 and the limit plate 2 16 can be adjusted to ensure that the angle of the limit plate 1 13 can fit the angle of the sheet metal part. Then the positioning block 44 is lowered to the initial position to carry out the next welding. After the welding of the next sheet metal part is completed, the above-mentioned lifting work is repeated, and the sheet metal part on the upper side falls on the sheet metal part on the lower side, so that multiple sheet metal parts can be neatly stacked.When the sheet metal parts are placed to a maximum number, according to the position of the gap between the two sheet metal parts at the bottom, the motor 4 24 is used to drive the threaded rod 5 25 to rotate, so that the adjustment plate 26 slides up and down, so that the paddle 1 30 is aligned with the gap between the sheet metal part at the bottom and the slide plate 38, and then the motor 5 35 is used to drive the threaded rod 6 37 to rotate, so that the paddle 2 31 rises and slides on the slide bar 5 36, and with the cooperation of the connecting rod 1 33 and the connecting rod 2 34, multiple paddles 3 32 move at the same time, and the spacing between the multiple paddles 3 32 is always consistent and equal to the spacing between the paddle 1 30, the paddle 2 31 and the adjacent paddle 3 32. Therefore, when any paddle 3 32 is aligned with the two After the gaps between the sheet metal parts are filled, the remaining three paddles 32 are also aligned with the gaps between the sheet metal parts. Then, the electric push rod 3 27 is used to drive the mounting frame 29 to move, so that the paddle 1 30, the paddle 2 31, and the paddle 3 32 are simultaneously inserted into the gaps between the sheet metal parts, so that the multiple sheet metal parts can be separated. Then, the paddle 2 31 is continued to be driven to rise, so that the spacing between the multiple paddles 3 32 can be expanded, so that the welds are no longer covered. At this time, the staff can intuitively observe the welds of multiple sheet metal parts and conduct comparative inspections to help the staff determine whether repair welding is needed, thereby ensuring the consistency of welding, and the orientations of multiple sheet metal parts are relatively uniform, and no work is required. It is convenient for personnel to frequently move their bodies for observation, and it is not easy to cause confusion during inspection. It also saves the process of manually sorting sheet metal parts by the staff, saving manpower. When the comparative inspection work is completed, when the sheet metal parts need to be transported or repaired, the paddle 32 is driven away from the sheet metal parts, and then the slide plate 38 is driven to slide, so that the bottom of the sheet metal parts loses support, so that the sheet metal parts can fall, and then they can be transported or repaired. In addition, a container can be placed under the sheet metal parts to receive the sheet metal parts, and then subsequent transportation work can be carried out. When the number of sheet metal parts is large and heavy, if multiple sheet metal parts fall into the container at the same time, it may It is difficult for the staff to lift it, which causes difficulty in transportation. Therefore, according to the actual transportation capacity of the staff, the motor 2 15 can be used to drive the threaded rod 3 14 to rotate, so that the L-shaped block 22 can be raised and lowered, and the partition 23 can be aligned with the gap between the two sheet metal parts. Then, the electric push rod 20 can be used to drive the partition 23 to move and insert it into the gap, so that the multiple sheet metal parts can be divided into upper and lower parts. At this time, the slide plate 38 is driven away from the bottom of the sheet metal part, so that the sheet metal part under the partition 23 can fall into the container. At this time, the staff only needs to transport part of the sheet metal parts, which reduces the difficulty of a single transport and reduces the labor intensity of the staff.Therefore, with the cooperation of the lifting positioning mechanism and the separated stacking positioning mechanism, multiple welded sheet metal parts can be uniformly stacked in the same place and separated from each other, so that the staff can visually observe the welds of multiple sheet metal parts and compare and check the quality of the welds to help the staff determine whether repair welding is needed, thereby ensuring the consistency of welding, and the orientation of multiple sheet metal parts is relatively uniform, and the staff does not need to move their bodies frequently for observation, which is more convenient and less likely to cause confusion during inspection, and also saves the staff from the process of manually sorting the sheet metal parts, and when the welded sheet metal parts need to be transported , a container can be placed under the stacked sheet metal parts, and then, according to the actual handling capacity of the staff, the motor 2 15 can be used to drive the threaded rod 3 14 to rotate, so that the L-shaped block 22 can be raised and lowered, and the partition 23 can be aligned with the gap between the two sheet metal parts, and then the electric push rod 20 can be used to drive the partition 23 to move and insert it into the gap, so that multiple sheet metal parts can be divided into upper and lower parts. At this time, the slide plate 38 is driven away from the bottom of the sheet metal parts, so that the sheet metal parts under the partition 23 can fall into the container. At this time, the staff only needs to transfer part of the sheet metal parts, which reduces the difficulty of single transfer work and reduces the labor intensity of the staff. ;
