Description

Technical Field

[0001] This utility model relates to the field of aluminum plate laser welding technology, and in particular to an aluminum plate laser welding machine with a flipping mechanism. Background Technology

[0002] In modern manufacturing, aluminum plate welding is an indispensable processing step in many fields, such as aerospace, automobile manufacturing, and electronic equipment production. With the rapid development of these industries, the requirements for the quality and efficiency of aluminum plate welding are becoming increasingly stringent. Traditional aluminum plate welding methods and equipment have gradually revealed many problems in practical applications, making it difficult to meet the diversified needs of modern production.

[0003] In traditional aluminum plate welding operations, the positioning process is a major challenge. In the past, the placement and fixing of aluminum plates to be welded mostly relied on manual operation. This method lacks precision and consistency. When positioning manually, it is difficult to avoid deviations in the position of the aluminum plates. Even experienced workers find it difficult to ensure that the position of the aluminum plates is exactly the same every time. This leads to poor joint accuracy between aluminum plates during the welding process, which can easily result in problems such as uneven welds and insufficient weld strength, seriously affecting the welding quality.

[0004] Traditional welding equipment lacks a convenient flipping function. In actual welding, aluminum plates often need to be welded on both sides to ensure welding strength and sealing. However, traditional equipment is extremely inconvenient to flip. Usually, the aluminum plate needs to be manually removed from the welding position, flipped, and then repositioned and installed. This process not only consumes a lot of time and manpower, but also the aluminum plate is easily damaged during repeated loading and unloading, which further affects the welding quality.

[0005] With the continuous upgrading of the manufacturing industry and the continuous expansion of production scale, higher requirements are placed on the efficiency and precision of aluminum plate welding. Enterprises urgently need a welding equipment that can quickly and accurately position aluminum plates and facilitate flipping operations in order to improve production efficiency, reduce production costs and ensure product quality. Utility Model Content

Enterprises urgently need a welding equipment that can quickly and accurately position aluminum plates and facilitate flipping operations in order to improve production efficiency, reduce production costs and ensure product quality. Therefore, this utility model is proposed.

[0007] Therefore, the purpose of this invention is to enable the aluminum plate to be welded to move when it is positioned so that the fixed connecting block moves the other positioning constraint plate when the aluminum plate to be welded is brought into contact with the positioning constraint plate. This allows the other aluminum plate to be welded to be effectively aligned. After laser welding is performed on one side of the aluminum plate, when it is necessary to flip the aluminum plate, the servo motor drives the rotating rod to rotate, and the aluminum plate to be welded placed on the support connecting plate is flipped. At the same time, under the action of the rotating connecting block and the fixed connecting block, the other support connecting plate and the aluminum plate to be welded above it are flipped together. This device can quickly and accurately position the aluminum plate and facilitate the flipping operation, thereby improving production efficiency.

[0017] The beneficial effects of this utility model are:

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] Reference Figure 1-4 This is the first embodiment of the present invention, which provides an aluminum plate laser welding machine with a flipping mechanism, including a welding fixed table 1 and two welding fixed plates 2 on one side of the welding fixed table 1. Each welding fixed plate 2 is provided with a rotating sleeve 3, and a rotating connecting rod 4 is provided inside each rotating sleeve 3. Each rotating connecting rod 4 is provided with a support fixed plate 5 installed on one side of each rotating connecting rod 4. Each support fixed plate 5 is provided with a constraint fixed plate 10 on one side of each support fixed plate 5. Each support fixed plate 5 is provided with a support connecting plate 6 on one side of each support connecting plate 6. Each support connecting plate 6 is provided with a limiting connecting block 8 on one side of each support connecting plate 6. Each limiting connecting block 8 is provided with a limiting connecting groove 9 on its inner side. Each limiting connecting block 8 is connected to the corresponding limiting connecting groove 9. Each support connecting groove 7 is provided with a support constraint plate 16 inside its inner side.

[0031] Each support constraint plate 16 has a positioning constraint block 20 on one side, one end of each positioning constraint block 20 is located inside the limiting connection groove 9, each positioning constraint block 20 has a positioning sleeve 21 on one side, each limiting connection groove 9 has an insertion constraint post 22 inside, one end of each insertion constraint post 22 is inserted into the corresponding positioning sleeve 21, each limiting connection groove 9 has a return spring 23 inside, each return spring 23 is sleeved on the corresponding positioning sleeve 21, and each of the two support constraint plates 16 has a rotating connection block 17 on one side.

[0032] Example 2

[0033] Reference Figure 3-6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that it includes a support constraint plate 16 installed inside each support connecting plate 6, a positioning constraint plate 18 on one side of each support constraint plate 16, a fixed connecting block 19 between two positioning constraint plates 18, a constraint sleeve 11 on one side of each support fixing plate 5, a constraint internal thread 12 on the inner side of each constraint sleeve 11, a lifting stud 13 on the inner side of each constraint internal thread 12, the constraint internal thread 12 on the inner side of the constraint sleeve 11 and the lifting stud 13 are connected by threads, and a lifting handle 14 is provided on one side of the lifting stud 13.

[0034] A lifting fixing block 15 is provided on one side of the lifting stud 13. An aluminum plate to be welded is provided between each lifting fixing block 15 and the support connecting plate 6. One side of the aluminum plate to be welded abuts against the positioning constraint plate 18. A bearing seat 24 is provided on one side of each welding fixing plate 2. One end of each rotating connecting rod 4 passes through the welding fixing plate 2 and is located inside the bearing seat 24. A servo motor 25 is provided on one side of some bearing seats 24. A rotating rod is provided on one side of the servo motor 25. One end of the rotating rod passes through the bearing seat 24 and is connected to the rotating connecting rod 4.

[0035] When using this aluminum plate laser welding machine, the aluminum plate to be welded is first placed on the support connecting plate 6, where the laser welding equipment is located above the aluminum plate to be welded, so that one side of the aluminum plate to be welded abuts against the positioning constraint plate 18. The positioning constraint plate 18 is installed inside the support connecting plate 6 through the support constraint plate 16, and a fixed connecting block 19 is provided between the two positioning constraint plates 18. This structure ensures that the position of the positioning constraint plate 18 is relatively fixed, thereby providing a stable positioning reference for the aluminum plate to be welded.

[0036] Rotating the lifting handle 14 causes the lifting stud 13 to move up and down within the constraint sleeve 11 due to the threaded connection between the lifting stud 13 and the constraint internal thread 12 on the inner side of the constraint sleeve 11. A lifting fixing block 15 is provided on one side of the lifting stud 13. As the lifting stud 13 moves, the lifting fixing block 15 gradually approaches the aluminum plate to be welded until the aluminum plate to be welded is tightly fixed between the lifting fixing block 15 and the support connecting plate 6, thus completing the fixing operation of the aluminum plate.

[0037] Start the laser welding equipment above the aluminum plate to be welded, and laser welding can be performed on one side of the aluminum plate. When it is necessary to flip the aluminum plate, start the servo motor 25. The rotating rod on one side of the servo motor 25 passes through the bearing seat 24 and is connected to the rotating connecting rod 4. The servo motor 25 drives the rotating rod to rotate, which in turn causes the rotating connecting rod 4 to rotate. The rotating connecting rod 4 is installed inside the rotating sleeve 3.

[0038] The rotating sleeve 3 is mounted on the welding fixing plate 2, and one end of the rotating connecting rod 4 passes through the welding fixing plate 2 and is located inside the bearing seat 24, which ensures the stability of the rotation of the rotating connecting rod 4. The rotation of the rotating connecting rod 4 drives the support fixing plate 5 to rotate. The support fixing plate 5 has a support connecting plate 6, a constraint fixing plate 10 and other components on one side, so these components will also rotate with the rotating connecting rod 4.

[0039] When the rotating connecting rod 4 rotates 180°, the aluminum plate to be welded placed on the supporting connecting plate 6 is flipped over. At the same time, under the action of the rotating connecting block 17 and the fixed connecting block 19, the other supporting connecting plate 6 and the aluminum plate to be welded above are flipped over together.

[0040] When flipping the aluminum plate, the displacement of the aluminum plate can be restricted, ensuring that the aluminum plate can maintain good positional accuracy after flipping. After the aluminum plate is flipped, laser welding can be performed on the other side of the aluminum plate. After welding is completed, the lifting handle 14 is rotated in the opposite direction to move the lifting fixing block 15 away from the aluminum plate to be welded, and the welded aluminum plate can be taken out to perform the welding operation of the next set of aluminum plates.

[0041] The remaining structure is the same as that in Example 1.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
