Description

Technical Field

[0001] The utility model belongs to the technical field of welding tooling, and specifically relates to a welding tooling for the bottom plate of a battery box. Background Technique

[0002] As an important part of the battery box, the welding quality and precision of the bottom plate of the battery box directly affect the overall performance and service life of the battery box. Therefore, a special welding tooling for the battery box needs to be used for operation;

[0003] When welding the bottom plate of the battery box, the existing welding tooling usually has a fixed size. However, since the volume of the battery box is usually determined according to the demand, the welding tooling needs to be replaced or adjusted. Therefore, when welding battery boxes of different sizes, a large amount of time is required to adjust the tooling, resulting in a reduction in the welding efficiency of the bottom plate of the battery box;

[0004] To solve the above problems, a welding tooling for the bottom plate of a battery box is proposed in this application. Content of the Utility Model

[0005] In view of the problems in the related art, the utility model proposes a welding tooling for the bottom plate of a battery box to overcome the above technical problems existing in the existing related art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A welding tooling for the bottom plate of a battery box includes a fixed frame. A fixed outer shell is fixedly connected to the outer side wall of the fixed frame. A motor is fixedly connected to the inside of the fixed outer shell. The output end of the motor is fixedly connected to a first bidirectional threaded rod. A first moving plate is threadedly connected to the outer side wall of the first bidirectional threaded rod. An end limiting frame is fixedly connected to the top of the first moving plate. A second bidirectional threaded rod is rotatably connected to the inside of the end limiting frame. One end of the second bidirectional threaded rod is fixedly connected to a first handle. A second moving plate is threadedly connected to the outer side wall of the second bidirectional threaded rod. A first buckle is fixedly connected to the top of the second moving plate. A second buckle is fixedly connected to the center of the top of the end limiting frame. A middle limiting frame is fixedly connected to the center of the top of the fixed frame.

[0008] Preferably, a first limiting ring is fixedly connected to the end of the first bidirectional threaded rod away from the motor, and a second limiting ring is fixedly connected to the end of the second bidirectional threaded rod away from the first handle.

[0009] By setting the first limiting ring and the second limiting ring, the first bidirectional threaded rod is limited by the first limiting ring, preventing the first bidirectional threaded rod from shaking during operation. The second bidirectional threaded rod is limited by the second limiting ring, preventing the second bidirectional threaded rod from falling off during operation.

[0010] Preferably, a connecting plate is fixedly connected to the outer side wall of the second buckle. A telescopic rod is fixedly connected to the center of the top of the connecting plate, and a fixed seat is fixedly connected to the telescopic end of the telescopic rod.

[0011] By setting the connecting plate, the telescopic rod and the fixed seat, the connecting plate is connected to the second buckle, enabling the connecting plate to limit and support the telescopic rod, and allowing the telescopic rod to drive the fixed seat to move up and down.

[0012] Preferably, a rotating shaft is rotatably connected to the inner side wall of the fixed seat. A limiting plate is fixedly connected to one end of the rotating shaft away from the fixed seat, and a threaded sleeve is fixedly connected to the other end of the rotating shaft away from the limiting plate.

[0013] By setting the rotating shaft, the limiting plate and the threaded sleeve, the threaded sleeve is limited and supported by the rotating shaft, keeping the threaded sleeve inside the fixed seat. The threaded sleeve limits and supports the limiting plate, enabling the threaded sleeve to rotate inside the fixed seat.

[0014] Preferably, a threaded column is threadedly connected to the inner side wall of the threaded sleeve. A second handle is fixedly connected to one end of the threaded column away from the fixed seat, and a pressing pad is fixedly connected to the other end of the threaded column away from the second handle.

[0015] By setting the threaded column, the second handle and the pressing pad, the threaded column is threadedly connected to the threaded sleeve, allowing the threaded column to move inside the threaded sleeve. The second handle drives the threaded column to move the pressing pad.

[0016] In summary, the technical effects and advantages of the present utility model are as follows: For this battery box bottom plate welding tooling, the first bidirectional threaded rod drives two first moving plates to move towards each other, causing two end limiting frames to move towards each other, thereby clamping and fixing both ends of the battery box bottom plate. The middle limiting frame can clamp and fix the middle of the battery box bottom plate, keeping the battery box bottom plate stable during welding. Moreover, different-sized battery box bottom plates can be clamped and fixed through adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Refer to Figures 1 - 3 , a welding tool for the bottom plate of a battery box, including a fixed frame 1. The outer side wall of the fixed frame 1 is fixedly connected with a fixed outer shell 2. The inside of the fixed outer shell 2 is fixedly connected with a motor 3. By using the fixed outer shell 2 to limit the motor 3, the motor 3 can be limited and supported to prevent the motor 3 from shaking during operation. The output end of the motor 3 is fixedly connected with a first bidirectional threaded rod 4. The outer side wall of the first bidirectional threaded rod 4 is threadedly connected with a first moving plate 5. The top of the first moving plate 5 is fixedly connected with an end limiting frame 6. The inside of the end limiting frame 6 is rotatably connected with a second bidirectional threaded rod 7. One end of the second bidirectional threaded rod 7 is fixedly connected with a first handle 8. The outer side wall of the second bidirectional threaded rod 7 is threadedly connected with a second moving plate 9. The top of the second moving plate 9 is fixedly connected with a first buckle 10. The center of the top of the end limiting frame 6 is fixedly connected with a second buckle 11. The center of the top of the fixed frame 1 is fixedly connected with a middle limiting frame 14. By driving the first bidirectional threaded rod 4 by the motor 3, the two first moving plates 5 move towards each other. The two first moving plates 5 are respectively fixed to the two symmetrically distributed end limiting frames 6, so that the two end limiting frames 6 move towards each other. The bottom plate of the battery box is clamped and fixed by the two end limiting frames 6 and the middle limiting frame 14. By driving the second bidirectional threaded rod 7 by the first handle 8, the two second moving plates 9 drive the two first buckles 10 to move towards each other, so that the bottom plate of the battery box can be clamped and fixed, and thus the bottom plates of battery boxes with different sizes can be clamped and fixed, thereby avoiding the shaking of the battery box during welding.

[0024] Reference Figures 2 - 3 As shown in Figures 2 - 3 , at one end of the first double - threaded rod 4 away from the motor 3, a first limiting ring 12 is fixedly connected. At one end of the second double - threaded rod 7 away from the first handle 8, a second limiting ring 13 is fixedly connected. The first double - threaded rod 4 is limited and supported by the first limiting ring 12 to prevent the first double - threaded rod 4 from shaking during operation, so that the first double - threaded rod 4 can operate stably. The second double - threaded rod 7 is limited and supported by the second limiting ring 13 to prevent the second double - threaded rod 7 from falling off or shifting during rotation.

[0025] Reference Figure 1 and Figure 4 As shown in Figure 1 and Figure 4 , on the outer side wall of the second buckle 11, a connecting plate 15 is fixedly connected. At the center of the top of the connecting plate 15, a telescopic rod 16 is fixedly connected. The telescopic end of the telescopic rod 16 is fixedly connected with a fixed seat 17. The connecting plate 15 supports and limits the telescopic rod 16, so that the telescopic rod 16 can support and drive the fixed seat 17, enabling the fixed seat 17 to move up and down. Thus, under the support of the connecting plate 15, the fixed seat 17 remains stable.

[0026] Reference Figure 4 As shown in Figure 4 , a rotating shaft 18 is rotatably connected to the inner side wall of the fixed seat 17. At one end of the rotating shaft 18 away from the fixed seat 17, a limiting plate 19 is fixedly connected. At one end of the rotating shaft 18 away from the limiting plate 19, a threaded sleeve 20 is fixedly connected. The rotating shaft 18 limits and supports the threaded sleeve 20, so that the threaded sleeve 20 is located at the center of the inside of the fixed seat 17. The limiting plate 19 limits the rotating shaft 18 to prevent the rotating shaft 18 from falling off during operation, enabling the threaded sleeve 20 to rotate inside the fixed seat 17.

[0027] Reference Figure 4 As shown in Figure 4 , a threaded column 21 is threadedly connected to the inner side wall of the threaded sleeve 20. At one end of the threaded column 21 away from the fixed seat 17, a second handle 22 is fixedly connected. At one end of the threaded column 21 away from the second handle 22, a pressing pad 23 is fixedly connected. By threading the threaded column 21 with the threaded sleeve 20, the second handle 22 can drive the threaded column 21 to rotate inside the threaded sleeve 20, enabling the threaded column 21 to move inside the threaded sleeve 20. Thus, the pressing pad 23 is driven by the threaded sleeve 20 to clamp and fix the battery box frame, and the position of the battery box frame can be adjusted to align the battery box frame with the battery box bottom plate, facilitating the welding of the bottom plate.

[0028] Working principle: The first bidirectional threaded rod 4 is driven to rotate by the motor 3, so that the first moving plate 5 drives two symmetrically distributed end limit frames 6 to move towards each other, and the four corners and the middle of the battery box bottom plate are clamped and fixed by the two end limit frames 6 and the middle limit frame 14. The first handle 8 drives the second bidirectional threaded rod 7 to make the two first buckles 10 move towards each other, so that the battery box bottom plates of different sizes can be clamped and fixed. The connecting plate 15 installed on the outer side wall of the second buckle 11 supports the telescopic rod 16, so that the telescopic rod 16 drives the fixed seat 17 to lift. The angle of the threaded column 21 can be adjusted by the threaded sleeve 20 through the rotating shaft 18, so that the threaded column 21 can drive the extrusion pad 23 to clamp and fix the battery box frame. The battery box frame is aligned with the battery box bottom plate by a plurality of arranged threaded columns 21. Through the contraction of the telescopic rod 16, the battery box frame contacts the battery box bottom plate, which is convenient for precise welding.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
