Description

Technical Field

[0001] This utility model belongs to the field of battery production technology, and in particular relates to a tooling fixture that is easy to adapt to clamping different battery packs. Background Technology

[0002] Battery pack fixtures are specialized tools used in the production, assembly, testing, and repair of battery packs. Their main functions include fixing, positioning, supporting, and connecting battery modules to ensure stability, safety, and consistency during production. Depending on their application, they can be categorized into assembly fixtures, testing fixtures, repair fixtures, and automated production line fixtures. Assembly fixtures are used for cell stacking, end-plate welding, and busbar installation, requiring high precision and short-circuit protection. Testing fixtures are used for charge / discharge testing and aging testing, typically integrating signal acquisition modules. Repair fixtures are used for battery disassembly and insulation testing, emphasizing safety. Automated fixtures work in conjunction with robots to achieve efficient handling and positioning. However, in practical use, they still have the following drawbacks:

[0003] In the process of working, the battery pack tooling fixture directly uses ordinary tooling fixtures for clamping. However, when clamping battery components of different sizes in production, if the battery components are directly placed on the fixture for clamping, even smaller batteries need to have their clamping structures adjusted one by one, which will affect work efficiency and make the battery pack tooling fixture not very applicable to the production of batteries of different sizes.

[0004] Secondly, the battery pack tooling fixture uses a screw that rotates, driving the clamping structure connected by threads on the circumference of the screw to push until it is clamped and secured with the tooling. However, during the clamping process, the direct threaded connection will cause the clamping structure to move unevenly, affecting the stability of the clamping. Utility Model Content

[0005] The purpose of this utility model is to provide a tooling fixture that is easy to adapt to clamping different battery packs. By setting a support base, mounting frame and positioning base, it solves the problems that the battery pack tooling fixture is not suitable for the production of batteries of different sizes and that the clamping mechanism is not stable enough, which affects the clamping stability.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a tooling fixture that is convenient to adapt to clamping different battery packs. It includes a support base, a mounting frame, and a positioning base. The positioning base is provided on one long side of the top of the support base. The positioning base is provided with a limit plate on its top. Mounting frames are provided above both ends of the positioning base. Support plates are fixed at the short sides of the top of the two mounting frames that are far apart from each other. Handles are rotatably connected inside the support plates. Threaded rods are fixed at the ends of the two handles that are close to each other. A connecting seat is threaded at the end of the threaded rod that is far away from the handle. In operation, the support base supports the mounting frame and the positioning base. The support plate on the mounting frame is connected to the handle. When the handle rotates, it drives the threaded rod to rotate, causing the connecting seat to move and clamp the battery pack on the top of the positioning base. The positioning base clamps the battery pack.

[0008] Furthermore, a fixing bracket is fixed to each of the two long sides at the bottom of the mounting bracket. The fixing bracket is fixed to the top of the support base and connected to the top of the support base to ensure that the mounting bracket is stably supported.

[0009] Furthermore, a slide rail is fixed to the top of the mounting bracket along a center line parallel to the long side, and a sliding channel steel is fixed to the bottom of the connecting seat corresponding to the position of the slide rail. The sliding channel steel is movably connected to the outside of the slide rail and sleeved on the outside of the slide rail, so that the connecting seat can slide smoothly along the slide rail.

[0010] Furthermore, a clamping frame is fixed to the outside of the connector, and the clamping frame is supported above the mounting frame. The clamping frame is fixed to the outside of the connector and is located above the mounting frame for directly clamping the battery assembly.

[0011] Furthermore, a limiting strip is fixed to one long side of the top of the positioning seat, and a vertical limiting slot is provided in the middle of one side of the limiting strip. The limiting strip is fixed to the long side of the top of the positioning seat, and a vertical limiting slot is provided in the middle of the limiting strip for detachable installation of the limiting plate.

[0012] Furthermore, the opening of the limiting slot is set towards the top center of the positioning seat, and a limiting plate is movably connected inside the limiting slot. The limiting plate is set above the center line parallel to the short side of the top of the positioning seat, and the opening of the limiting slot faces the center of the positioning seat. The limiting plate can be inserted into the slot, and different spaces can be separated by adjusting the position of the limiting plate to meet the positioning needs of large and small batteries.

[0013] This utility model has the following beneficial effects:

[0014] This invention solves the problem of insufficient applicability of battery pack tooling fixtures to the production of batteries of different sizes by setting a support base and a positioning base. When a larger battery component needs to be installed on the top of the positioning base, the limiting plate is removed from the limiting slot on the limiting strip, the battery component is placed on the positioning base, and pushed until it contacts the limiting strip on the top of the positioning base, thus limiting the position of the battery component. After being clamped in position by the clamping brackets above the two mounting brackets, the battery component is clamped on the top of the positioning base. When a smaller battery component needs to be installed on the top of the positioning base, one end of the limiting plate is inserted into the limiting slot, dividing the top of the positioning base into two positions for supporting and clamping the battery component. This allows the top of the positioning base to easily adapt to clamping battery components of different sizes, thus improving its applicability.

[0015] This invention solves the problem of unstable movement and poor clamping stability of the battery pack tooling fixture by setting up a support base and mounting bracket. When clamping the battery, the battery is placed on the positioning base, and the handle can be rotated. During the rotation of the handle, the threaded rod is driven to rotate, and during the rotation of the threaded rod, the connecting base is driven to move, causing the clamping base on the outside of the connecting base to clamp the battery assembly on the top of the positioning base, thus clamping the battery assembly. During the movement of the connecting base above the support base, the two sliding channel steels at the bottom of the connecting base slide on the slide rail at the top of the mounting bracket, ensuring that the connecting base can slide stably.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0025] Please see Figure 1-3 This utility model is a tooling fixture that is easy to adapt to clamping different battery packs. It includes a support base 1, a mounting bracket 2, and a positioning base 3. The positioning base 3 is provided on one long side of the top of the support base 1. The top of the positioning base 3 is provided with a limit plate 302. The support base 1 supports the mounting bracket 2 and the positioning base 3. The positioning base 3 supports the battery pack being processed. Mounting brackets 2 are provided on the top of both ends of the positioning base 3. The mounting brackets 2 provide mounting for the battery clamping structure. The tops of the two mounting brackets 2 are far apart from each other. A support plate 206 is fixed to each of the short sides. The support plate 206 rotatably connects the handle 207. The handle 207 is rotatably connected inside the support plate 206. When the handle 207 rotates, it drives the threaded rod 205 to rotate. The ends of the two handles 207 that are close to each other are fixed with threaded rods 205. The end of the threaded rod 205 that is away from the handle 207 is threadedly connected to the connecting seat 203. When the threaded rod 205 rotates, it drives the connecting seat 203 to change position through the threaded connection between the threaded rod 205 and the connecting seat 203.

[0026] Specifically, the mounting bracket 2 has a fixing bracket 208 fixed on both long sides of the bottom of the mounting bracket 2. The fixing bracket 208 is fixed to the top of the support base 1, and the fixing bracket 208 on the mounting bracket 2 fixes the mounting bracket 2 to the top of the support base 1.

[0027] Furthermore, a slide rail 201 is fixed to the top of the mounting bracket 2 along a center line parallel to the long side, and a sliding channel steel 202 is fixed to the bottom of the connecting seat 203 corresponding to the position of the slide rail 201. The sliding channel steel 202 is movably connected to the outside of the slide rail 201, and the sliding channel steel 202 at the bottom of the connecting seat 203 is movably connected to the slide rail 201, so that the connecting seat 203 can slide on the mounting bracket 2.

[0028] Furthermore, a clamping frame 204 is fixed to the outside of the connecting seat 203. The clamping frame 204 is supported above the mounting frame 2, and the clamping frame 204 on the connecting seat 203 clamps the battery assembly on the positioning seat 3.

[0029] The operation process of this embodiment is as follows: During operation, when the battery is clamped, the battery is placed on the positioning seat 3, and the handle 207 can be rotated. During the rotation of the handle 207, the threaded rod 205 is driven to rotate. During the rotation of the threaded rod 205, the connecting seat 203 is pushed to move, causing the clamping seat on the outside of the connecting seat 203 to clamp the battery assembly on the top of the positioning seat 3. The battery assembly is clamped. During the movement of the connecting seat 203 above the support seat 1, the two sliding channel steels 202 at the bottom of the connecting seat 203 slide on the slide rail 201 on the top of the mounting frame 2, ensuring that the connecting seat 203 can slide stably. Specific Implementation Example 2

[0030] Please see Figure 1 , 4 5. Based on the first specific embodiment, a limiting strip 301 is fixed at one long side of the top of the positioning seat 3. A vertical limiting slot 3011 is opened in the middle of one side of the limiting strip 301. The limiting strip 301 on the positioning seat 3 restricts and determines the side position of the battery assembly, and is movably connected to the limiting plate 302 through the limiting slot.

[0031] Specifically, the opening of the limiting slot 3011 is set towards the top center of the positioning seat 3. The limiting slot 3011 is movably connected to the limiting plate 302. The limiting plate 302 is set above the center line parallel to the short side of the top of the positioning seat 3. The limiting plate 302 on the limiting strip 301 restricts and determines the position of the two battery components. Different clamping spaces are separated on the top of the positioning seat 3 by the limiting plate 302 to accommodate the clamping of battery components of different sizes.

[0032] The operation process of this embodiment is as follows: When a larger battery component needs to be installed on the top of the positioning seat 3, the limiting plate 302 is removed from the limiting slot 3011 on the limiting strip 301, the battery component is placed on the positioning seat 3, and the battery component is pushed until it contacts the limiting strip 301 on the top of the positioning seat 3 to restrict the position of the battery component. After the position is clamped by the clamping brackets 204 above the two mounting brackets 2, the battery component is clamped on the top of the positioning seat 3. When a smaller battery component needs to be installed on the top of the positioning seat 3, one end of the limiting plate 302 is inserted into the limiting slot 3011, and two positions for supporting and clamping the battery component are separated on the top of the positioning seat 3, so that the top of the positioning seat 3 can be adapted to clamp battery components of different sizes.
