DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0032] Example 1

[0033] Reference Figure 1-Figure 8 A welding positioning device comprises: a workbench 1, a positioning groove 22 with a moderate depth and a shape matching the bottom contour of a battery box 13 is processed at the center of the top. The positioning groove 22 is used to accurately place and position the battery box 13 to ensure stability during welding.

[0034] On the top of the workbench 1, a plurality of slidably adjustable positioning blocks 10 are installed according to the distribution position of the connecting ears 12 outside the battery box 13. Two connecting blocks 7 and two supporting frames 8 are fixed on the top of the workbench 1. The two connecting blocks 7 and the supporting frames 8 are respectively arranged at the four corners of the top of the workbench 1, and the supporting frames 8 can support the rotating frame 3 after the flip. The adjacent connecting blocks 7 and supporting frames 8, the supporting frames 8 and the supporting frames 8, and the connecting blocks 7 and the connecting blocks 7 are fixed with first guide rods 9. The positioning block 10 is slidably sleeved on the first guide rod 9. The outer side of the positioning block 10 is provided with a first bolt 11 through the thread. One end of the first bolt 11 is in conflict with the first guide rod 9, which is used to fix the positioning block 10. By rotating the first bolt 11 so that one end of it is in close conflict with the first guide rod 9, the position of the positioning block 10 is accurately fixed. After the battery box 13 is placed in the positioning groove 22, the position of each positioning block 10 is adjusted so that it fits tightly with the connecting ear 12 to achieve the preliminary positioning of the connecting ear 12.

[0035] A positioning post 21 is fixedly provided on the top of the positioning block 10 and is used in conjunction with the mounting hole 20 on the connecting ear 12 to further position the connecting ear 12.

[0036] Place the new energy vehicle battery box 13 stably in the positioning groove 22 of the workbench 1, adjust the position of each positioning block 10 so that the top positioning column 21 is accurately inserted into the mounting hole 20 of the connecting ear 12, and fix the positioning block 10 by rotating the first bolt 11 to complete the preliminary positioning of the battery box 13 and its connecting ear 12.

[0037] On one side of the workbench 1, a rotating rod 14 is installed through a bearing seat so that it can rotate freely around a vertical axis. The rotating frame 3 is fixed on the rotating rod 14, and additional support is provided through the extension frame 2 to enhance stability during rotation. The worm gear reducer 15 and the motor 16 are respectively fixedly installed on the other side of the workbench 1, and the output shaft of the motor 16 is connected to the input shaft of the worm gear reducer 15, and the output shaft of the worm gear reducer 15 is connected to the rotating rod 14, so that the rotating frame 3 is driven by the motor 16 to realize the flipping function.

[0038] The lifting frame 4 is installed on the rotating frame 3, and a plurality of limiting components are designed inside the lifting frame 4 to fix and limit the first reinforcing rib 5 and the plurality of second reinforcing ribs 6 before flipping. These limiting components need to ensure that when the lifting frame 4 is matched with the battery box 13, the limiting of the reinforcing ribs can be automatically released to facilitate welding operations.

[0039] A positioning portion 26 used in conjunction with the first reinforcing rib 5 is provided on one side of the second reinforcing rib 6, so that during the placement of the first reinforcing rib 5, a plurality of second reinforcing ribs 6 can be further positioned.

[0040] The plurality of first reinforcing ribs 5 are placed in the limiting assembly of the lifting frame 4, and the fixing function of the limiting assembly is used to ensure the stability of the position of the first reinforcing ribs 5. Subsequently, the second reinforcing ribs 6 are placed on the positioning portions 26 of the first reinforcing ribs 5. Due to the design of the positioning portions 26, the placement of the second reinforcing ribs 6 will further strengthen the limiting function of the plurality of first reinforcing ribs 5.

[0041] The motor 16 is started, and the worm gear reducer 15 drives the rotating rod 14 and the rotating frame 3 to rotate, so that the lifting frame 4 and the reinforcing rib assembly thereon are flipped over to the top of the battery box 13. As the flipping action is completed, the lifting frame 4 contacts the battery box 13 and automatically releases the limit of the reinforcing rib. At this time, the first reinforcing rib 5 and the second reinforcing rib 6 have been accurately aligned to the preset position of the battery box 13, ready for welding.

[0042] After the reinforcing ribs and the battery box 13 are accurately positioned, welding equipment is used to weld the connection between the reinforcing ribs and the battery box 13. Due to the accurate positioning in the early stage, there is no need to frequently adjust the position during the welding process, which greatly improves the welding efficiency and quality.

[0043] A plurality of second guide rods 17 are slidably provided through the top of the rotating frame 3, the tops of these second guide rods 17 are fixedly connected to the first connecting plate 23, and the bottoms are connected through the connecting strips 18. An electric push rod 19 is fixedly installed at the bottom of the rotating frame 3, and its output end is fixedly connected to the connecting strip 18. When the rotating frame 3 is flipped to an appropriate position, the electric push rod 19 is started, and the connecting strip 18 and the second guide rod 17 are moved up and down as a whole through its telescopic effect, thereby driving the lifting frame 4 and the first reinforcing ribs 5 and the second reinforcing ribs 6 to move into the battery box 13, completing the positioning process before welding.

[0044] The core part of the position limiting assembly is composed of a fixing bar 30 and a sliding rod 31. A plurality of fixing bars 30 are fixedly mounted on the top of one side of the first connecting plate 23 and the second connecting plate 24. Two sliding rods 31 are slidably arranged in each fixing bar 30, and one end of the sliding rod 31 is fixedly connected to a sliding block 32. A wedge block 33 is arranged on the top of the sliding block 32, and the wedge block 33 is used in conjunction with the first reinforcing rib 5 and the second reinforcing rib 6 to achieve a clamping effect.

[0045] The outer wall of the sliding rod 31 is provided with a spring 34, and the two ends of the spring 34 are respectively fixedly connected to the sliding block 32 and the side of the fixing bar 30 that is close to each other. When the first reinforcing rib 5 and the second reinforcing rib 6 are placed on the lifting frame 4, the wedge block 33 automatically clamps the reinforcing rib inward under the action of the spring 34 to achieve stable fixation. When the lifting frame 4 flips over and moves toward the inside of the battery box 13, the wedge block 33 contacts and is squeezed with the edge of the battery box 13, so that the sliding block 32 drives the sliding rod 31 to move outward, and the spring 34 is compressed, thereby automatically releasing the clamping of the first reinforcing rib 5 and the second reinforcing rib 6, so that they can smoothly enter the inside of the battery box 13.

[0046] The present application can be used in the field of battery case processing, and can also be used in other fields applicable to the present application.

[0047] Example 2

[0048] refer to Figure 1-Figure 8 , improved on the basis of Example 1: A welding positioning device for a battery case of a new energy vehicle, which is applied to the field of battery case processing, and the lifting frame 4 is mainly composed of a first connecting plate 23 and a second connecting plate 24. The first connecting plate 23 serves as a basic support, and a slide rail or a guide groove is designed on its top so that the second connecting plate 24 can slide along these guide grooves. A second bolt 29 is provided through the top of the second connecting plate 24, and a plurality of threaded holes 28 are correspondingly provided on the top of the first connecting plate 23. By rotating the second bolt 29 and making it cooperate with different threaded holes 28, the specific position of the second connecting plate 24 on the first connecting plate 23 can be adjusted to adapt to first reinforcing ribs 5 of different sizes or layouts.

[0049] In order to ensure the accurate positioning of the first reinforcing rib 5 and the second reinforcing rib 6 on the lifting frame 4, a plurality of guide posts 25 are fixedly provided on the top of the second connecting plate 24 and the first connecting plate 23. The sizes of these guide posts 25 match the positioning holes 27 on the first reinforcing rib 5 and the second reinforcing rib 6, and after being inserted, the reinforcing ribs can be guided and initially positioned to ensure accurate alignment before welding.

[0050] The spacing between the wedge block 33 and the second connecting plate 24 and the first connecting plate 23 is precisely designed to match the thickness of the first reinforcing rib 5 and the second reinforcing rib 6 to ensure the stability of clamping and the smoothness of release.

[0051] In the present application, when in use, the battery box 13 is placed in the positioning groove 22, and then the positioning block 10 is pushed to move on the first guide rod 9 according to the welding position of the connecting ear 12. After the movement and adjustment are completed, the first bolt 11 is screwed so that one end of the first bolt 11 is in conflict with the first guide rod 9, and then the connecting ear 12 is placed on the corresponding positioning block 10, and the positioning column 21 is inserted into the mounting hole 20 on the connecting ear 12, and welding is performed;

[0052] Then another person places a plurality of second reinforcing ribs 6 on a plurality of second connecting plates 24, and inserts the guide column 25 into the corresponding positioning hole 27. The bottom of the placed second reinforcing ribs 6 will abut against the wedge block 33, and then the wedge block 33 is pulled outward to make the second reinforcing ribs 6 abut against the second connecting plate 24, and then the wedge block 33 is released. The wedge block 33 can be reset and moved under the action of the spring 34, and cooperate with the second connecting plate 24 to limit the second reinforcing ribs 6. Then the first reinforcing rib 5 is placed on the first connecting plate 23, and is located between the second reinforcing ribs 6 on both sides, and is stuck in the positioning portion 26, which can further limit the second reinforcing ribs 6 on both sides, and is also fixed by the wedge blocks 33 on both sides, and then welded in sequence;

[0053] Subsequently, the starting motor 16 drives the worm gear reducer 15 to rotate, and the rotation of the worm gear reducer 15 can drive the rotating rod 14 to rotate, and the rotation of the rotating rod 14 can drive the rotating frame 3 to flip toward the workbench 1 until the rotating frame 3 hits the two support frames 8. At this time, the second reinforcing rib 6 and the first reinforcing rib 5 are located above the battery box 13, and then the electric push rod 19 is started to retract, which can drive the connecting bar 18 to move downward. The downward movement of the connecting bar 18 can drive multiple second guide rods 17 to move downward at the same time, which can drive the first connecting plate 23 to move downward. The downward movement of the first connecting plate 23 can The second connecting plate 24 can be driven to move downward, thereby simultaneously driving the welded first reinforcing rib 5 and the second reinforcing rib 6 to move downward, so that they move into the battery box 13. During the downward movement, the wedge block 33 is pushed to move by the edge of the rotating frame 3, and the wedge block 33 is separated from the first reinforcing rib 5 and the second reinforcing rib 6. At this time, the welded first reinforcing rib 5 and the second reinforcing rib 6 can move downward under gravity, and can also be guided by multiple guide columns 25 during the downward movement until the first reinforcing rib 5 and the second reinforcing rib 6 contact the inner wall of the rotating frame 3 and are welded;

[0054] After welding is completed, the motor 16 and the worm gear reducer 15 are restarted to reset and rotate, driving the rotating frame 3 to flip onto the extension frame 2, and then the first reinforcing rib 5 and the second reinforcing rib 6 as well as the first connecting plate 23 and the connecting ear 12 are welded in sequence using the above method.

[0055] However, as is well known to those skilled in the art, the working principles and wiring methods of the motor 16 and the electric push rod 19 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0056] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
