Description

Technical Field

[0001] This utility model relates to the field of battery swapping base positioning technology, specifically, to a battery swapping base welding positioning device. Background Technology

[0002] A battery swapping stand is a support and connection structure specifically designed for replacing device batteries. It typically features a robust frame structure that precisely adapts to the battery specifications of specific devices. Its surface has multiple positioning points to ensure accurate and precise insertion and alignment of the battery during installation. Simultaneously, the battery swapping stand is equipped with a comprehensive electrical connection system, including contact plates and circuit interfaces. These components quickly and stably establish an electrical connection after the battery is installed, ensuring no power interruption or electrical malfunction occurs during battery replacement.

[0003] The current welding process for battery swapping bases still relies on a relatively traditional manual operation mode: operators must first strictly refer to the detailed dimensional parameters marked on the design drawings to accurately calculate the connection length of each component; then, using conventional measuring tools, they must measure and pre-arrange each component, and finally fix the components into a whole structure by manual welding. Although this process can meet the spatial position requirements of the drawings at the basic positioning level, its entirely manual intervention has exposed significant shortcomings in actual production. Due to the lack of stable mechanical fixing devices, the workpiece is easily affected by factors such as operational vibration, equipment vibration, or external force during assembly and welding, resulting in positional deviation or deformation, which in turn leads to low product quality and precision. Although some battery swapping bases use bolt fastening for positioning, the installation and disassembly process requires repeatedly tightening / loosening multiple bolts, which is cumbersome and time-consuming, further reducing overall production efficiency. Utility Model Content

[0004] To overcome the above-mentioned defects, this utility model provides a welding positioning device for battery swapping bases. It solves the technical problem that in the existing technology, the fully manual intervention characteristic makes the workpiece susceptible to positional displacement or deformation during assembly and welding due to the lack of stable mechanical fixing devices in actual production. This results in low product quality and precision.

[0005] According to one aspect, at least one embodiment of the present invention provides a welding positioning device for a battery swapping base, comprising: The support leg has a positioning plate fixedly connected to its top by bolts. The top of the support leg has a moving groove, and the top of the positioning plate abuts against the battery swapping base body. The mounting components are provided in multiple sets and are located on the top of the battery swapping base body. Each mounting component includes a fixing rod located on the top of the battery swapping base body. The fixing rod has an insertion part on its exterior and a pressing groove and a limiting groove on its side. Two locking blocks are symmetrically arranged inside the fixing rod. The locking blocks have a pressing part and a limiting part on their side. The pressing part extends to the outside of the fixing rod through the pressing groove, and the limiting part extends to the outside of the fixing rod through the limiting groove. The limiting component is disposed on the side of the battery swapping base body and on the top of the support leg.

[0006] For example, in at least one embodiment of the present invention, a welding positioning device for a battery swapping base is provided, which further includes: a mounting groove is provided on the top of the positioning plate, the limiting part and the mounting groove are inserted and fixed, the two locking blocks are fixedly connected by a spring, and an elastic damping rod is provided inside the spring.

[0007] For example, in at least one embodiment of the present invention, a welding positioning device for a battery swapping base is provided, which further includes: the limiting member includes an L-shaped limiting plate disposed on the side of the battery swapping base body, the two right-angle plates of the L-shaped limiting plate are fixedly connected by a reinforcing block, and a limiting hole is provided through the top of the L-shaped limiting plate, the limiting hole being engaged by an mounting member and a mounting groove.

[0008] For example, in at least one embodiment of the present invention, a welding positioning device for a battery swapping base is provided, which further includes: two second adjusting screws are provided on the side of the L-shaped limiting plate, the two second adjusting screws are threadedly connected to the L-shaped limiting plate, and an abutment block is fixedly connected to the side of the second adjusting screw, and the abutment block has anti-slip texture on its side.

[0009] For example, in at least one embodiment of the present invention, a welding positioning device for a battery swapping base is provided, which further includes: a clamping assembly provided at the bottom of the positioning plate, the clamping assembly including a bidirectional motor fixedly installed at the bottom of the positioning plate and a fixing plate symmetrically fixedly connected to the bottom of the positioning plate.

[0010] For example, in at least one embodiment of the present invention, a welding and positioning device for a battery swapping base is provided, which further includes: a drive screw fixedly connected to both sides of the bidirectional motor via bearings, and the side of the drive screw being rotatably connected to the fixing plate.

[0011] For example, in at least one embodiment of the present invention, a welding and positioning device for a battery swapping base is provided, which further includes: a driving block is externally threaded to the driving screw, a movable plate is fixedly connected to the top of the driving block, and the bottom of the movable plate is slidably connected to the movable groove.

[0012] For example, in at least one embodiment of the present invention, a welding positioning device for a battery swapping base is provided, which further includes: a first adjusting screw threadedly connected to the side of the moving plate, a clamping plate rotatably connected to the side of the first adjusting screw, a limiting rod fixedly connected to the side of the clamping plate, and the limiting rod and the moving plate being inserted into each other.

[0013] The beneficial effects of the embodiments of this utility model are as follows: (1) In this utility model, the battery swapping base can be stably fixed on the top of the positioning plate through the coordinated cooperation of the mounting component and the limiting component. During installation, the battery swapping base is first placed on the top of the positioning plate; then the pressing parts on both sides of the mounting component are pressed, the middle spring is compressed and contracted, and the limiting part is driven to retract into the limiting groove; at this time, the plug-in part is passed through the positioning hole of the battery swapping base until it extends into the mounting groove; after releasing the pressing part, the spring rebounds and resets, pushing the locking block into the limiting groove, so that the limiting part and the mounting groove are locked together, thereby realizing the rapid positioning and installation of the battery swapping base and the positioning plate. Compared with the traditional bolt fastening method, the structure design of the mounting component is simple, the operation process is convenient and efficient, and the positioning time is significantly shortened. In addition, the limiting component and the mounting component form a combined limiting structure: by turning the second adjusting screw, the abutment block is driven to move, so that it abuts tightly against the side of the battery swapping base, further restricting the horizontal displacement of the battery swapping base, forming a multi-dimensional constraint with the vertical insertion and locking of the mounting component, and jointly improving the positioning stability of the battery swapping base.

[0014] (2) This utility model, by setting a clamping component, can accurately clamp both sides of the battery swapping base, effectively improving the stability of the welding process. After the limiting component and the mounting component complete the basic fixation of the battery swapping base, the bidirectional motor is started and drives the drive screw to rotate. The drive screw pushes the drive block to move along the guide track through the thread transmission, thereby driving the fixing plate to approach both sides of the battery swapping base. The clamping plate moves with the fixing plate and flexibly fits against the side of the battery swapping base to form a lateral constraint. Compared with the structure that relies solely on bolt positioning, this clamping component, through a bidirectional drive mechanical linkage design, can adaptively adjust the clamping force, significantly improving the welding quality and dimensional accuracy. In addition, in response to the need for compensation of small displacements that may occur during the welding process, an elastic adjustment mechanism is set between the clamping plate and the fixing plate in the design. When a small gap is generated between the clamping plate and the battery swapping base due to vibration, the clamping plate can be driven to move slightly by turning the first adjustment screw, and re-fit against the side of the battery swapping base to achieve dynamic compensation function and ensure the positioning stability throughout the welding process.

[0023] like Figures 1-6 As shown, it illustrates a welding and positioning device for a battery swapping base according to an embodiment of the present invention, comprising: Support leg 1, the top of support leg 1 is fixedly connected to positioning plate 2 by bolts, the top of support leg 1 is provided with moving groove 3, and the top of positioning plate 2 abuts against battery swapping base body 4. Mounting component 7, multiple sets of mounting components 7 are provided, and the mounting components 7 are set on the top of the battery swapping base body 4. The mounting component 7 includes a fixing rod 701 set on the top of the battery swapping base body 4. The fixing rod 701 has a plug-in part 702 on its outside. The side of the fixing rod 701 is provided with a pressing groove 703 and a limiting groove 704 respectively. Two locking blocks 708 are symmetrically arranged inside the fixing rod 701. The side of the locking block 708 is provided with a pressing part 705 and a limiting part 706. The pressing part 705 extends to the outside of the fixing rod 701 through the pressing groove 703, and the limiting part 706 extends to the outside of the fixing rod 701 through the limiting groove 704. The top of the positioning plate 2 is provided with an installation groove 8. The limiting part 706 is inserted and fixed to the installation groove 8. The two locking blocks 708 are fixedly connected by a spring 707. An elastic damping rod is provided inside the spring 707. Limiting component 6 is provided on the side of the battery swapping base body 4 and on the top of the support leg 1. The limiting component 6 includes an L-shaped limiting plate 601 disposed on the side of the battery swapping base body 4. The two right-angled plates of the L-shaped limiting plate 601 are fixedly connected by a reinforcing block 602. A limiting hole 603 is provided through the top of the L-shaped limiting plate 601. The limiting hole 603 is engaged by the mounting component 7 and the mounting groove 8. The L-shaped limiting plate 601 has two second adjusting screws 604 on its side. The two second adjusting screws 604 are threaded to the L-shaped limiting plate 601. The side of the second adjusting screw 604 is fixedly connected to an abutment block 605. The side of the abutment block 605 is provided with anti-slip texture 606.

[0024] In this embodiment, the battery swapping base body 4 can be stably fixed on the top of the positioning plate 2 through the coordinated cooperation of the mounting component 7 and the limiting component 6. The specific structure and workflow are as follows: During installation, the battery swapping base body 4 is first placed on the top of the positioning plate 2; then, the mounting component 7 is operated—pressing the pressing parts 705 on both sides causes the middle spring 707 to contract under pressure, driving the limiting part 706 to retract into the limiting groove 704; at this time, the insertion part 702 passes through the positioning hole of the battery swapping base body 4 until it extends into the mounting groove 8; after releasing the pressing part 705, the spring 707 rebounds and resets, pushing the locking block 708 into the limiting groove 704, so that the limiting part 706 and the mounting groove 8 are locked together, thereby achieving rapid positioning and installation of the battery swapping base body 4 and the positioning plate 2. Compared with the traditional bolt fastening method, the mounting component 7 has a simple structural design, convenient and efficient operation, and significantly shortens the positioning time. In addition, the limiting component 6 and the mounting component 7 form a combined limiting structure: by turning the second adjusting screw 604, the abutment block 605 is driven to move, so that it abuts tightly against the side of the battery swapping base body 4, further restricting the horizontal displacement of the battery swapping base body 4. This, together with the vertical insertion and locking of the mounting component 7, forms a multi-dimensional constraint, which together improves the positioning stability of the battery swapping base body 4. In order to ensure that the mounting groove 8 and the positioning hole of the battery swapping base body 4 are accurately matched, the two adopt a matching design - for different models of battery swapping base body 4, a special positioning plate 2 is configured to match it.

[0025] like Figures 2-8 As shown, it illustrates a clamping component 5 in another embodiment of the present invention. The bottom of the positioning plate 2 is provided with a clamping component 5. The clamping component 5 includes a bidirectional motor 501 fixedly installed at the bottom of the positioning plate 2 and a fixing plate 503 symmetrically fixedly connected to the bottom of the positioning plate 2. Both sides of the bidirectional motor 501 have drive screws 502 fixedly connected to the power shafts via bearings, and the side of the drive screws 502 is rotatably connected to the fixing plate 503. The drive screw 502 is externally threaded with a drive block 504, the top of the drive block 504 is fixedly connected with a movable plate 505, and the bottom of the movable plate 505 is slidably connected to the movable groove 3. The side of the movable plate 505 is threadedly connected to a first adjusting screw 507, and the side of the first adjusting screw 507 is rotatably connected to a clamping plate 506. The side of the clamping plate 506 is fixedly connected to a limit rod 508, and the limit rod 508 and the movable plate 505 are inserted into each other.

[0026] In this embodiment, through the dual positioning system of clamping component 5, limiting component 6, and mounting component 7 working together, the clamping component 5 can precisely clamp both sides of the battery swapping base body 4, effectively improving the stability of the welding process. Specifically, after the limiting component 6 and mounting component 7 complete the basic fixation of the battery swapping base body 4, the bidirectional motor 501 is started and drives the drive screw 502 to rotate. The drive screw 502 pushes the drive block 504 to translate along the guide rail through thread transmission, thereby driving the fixing plate 503 to approach both sides of the battery swapping base body 4. During this process, the clamping plate 506 moves with the fixing plate 503 and flexibly fits against the side of the battery swapping base body 4, forming a lateral constraint. Compared with the structure that relies solely on bolt positioning, the clamping component 5, through its bidirectional drive mechanical linkage design, can adjust the clamping force, improving welding quality and dimensional accuracy. In addition, to address the need for compensation for minor displacements that may occur during the welding process, an elastic adjustment mechanism is designed between the clamping plate 506 and the fixing plate 503. When a minor gap is generated between the clamping plate 506 and the battery swapping base body 4 due to vibration, the clamping plate 506 can be driven to move slightly by turning the first adjusting screw 507, so that it can re-fit against the side of the battery swapping base, thereby achieving dynamic compensation and ensuring the positioning stability throughout the welding process. The bidirectional motor 501 is controlled by a PLC, which can precisely control the clamping force.
