Description

Technical Field

[0001] This utility model relates to the field of lithium battery processing technology, and in particular to a lithium battery tooling frame for electric vehicles. Background Technology

[0002] Electric vehicle lithium battery tooling racks are an indispensable piece of equipment in the production, assembly, and maintenance of electric vehicle lithium batteries. They provide a reliable guarantee for the precise positioning, efficient assembly, and safe fixation of lithium batteries. Engineers can use tooling racks to quickly build test platforms to verify battery performance and safety.

[0003] However, the existing tooling racks have the following problems: when testing or repairing different types of lithium batteries, it is inconvenient for the rack to fit and fix them, which poses a safety hazard. In addition, when using the rack, it is generally directly fixed to the workbench, making it inconvenient to disassemble and assemble. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the existing technology where the frame is inconvenient to fit and fix different types of lithium batteries during testing or maintenance, which poses a safety hazard. In addition, the frame is generally directly fixed to the workbench during use, which makes it inconvenient to disassemble and assemble. Therefore, this utility model proposes an electric vehicle lithium battery tooling frame.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An electric vehicle lithium battery fixture includes a placement plate with rectangular holes for heat dissipation. The four corners of the placement plate are rounded. A partition for placing lithium battery blocks is fixedly connected to the top of the placement plate. Limiting plates are fixedly connected to the front and rear sides of the four partitions. An adjustment mechanism for fixing different lithium batteries is provided on the placement plate. A disassembly and assembly mechanism for disassembling the fixture is provided at the bottom of the placement plate.

[0007] In one possible design, the adjusting mechanism includes two adjusting plates, multiple sliding grooves, two pressure sensors, four first connecting blocks, two second connecting blocks, four first connecting plates, two second connecting plates, two positioning rods, a bidirectional lead screw, and a motor. The multiple sliding grooves are respectively disposed on the two adjusting plates. The two adjusting plates are slidably fitted onto the multiple partitions via the sliding grooves. The tops of the two second connecting blocks are fixedly connected to the center of the bottom of the two adjusting plates. The bottoms of the two second connecting blocks slide through rectangular holes and are threaded onto the same bidirectional lead screw. The two ends of the bidirectional lead screw are respectively close to the two second connecting plates. One side of the motor is rotatably connected, and the top of the two No. 2 connecting plates is fixedly connected to the bottom of the same placement plate. One side of the motor is fixedly connected to one side of the No. 2 connecting plate by bolts, and the output shaft of the motor rotates through the No. 2 connecting plate and is fixedly connected to one end of the bidirectional lead screw. The top of the four No. 1 connecting blocks is fixedly connected to the bottom sides of the two adjustment plates respectively. The bottom of the four No. 1 connecting blocks slides through two rectangular holes and slides on two positioning rods respectively. The two ends of the two positioning rods are fixedly connected to one side of the four No. 1 connecting plates respectively. The top of the four No. 1 connecting plates is fixedly connected to the bottom of the same placement plate.

[0008] In one possible design, the disassembly and assembly mechanism includes two rotating handles, two threaded posts, two base frames, and two clamping plates. The bottoms of the two rotating handles are fixedly connected to the tops of the two threaded posts, and the bottom ends of the two threaded posts are threaded through the top two sides of the same placement plate and the tops of the two base frames. The tops of the two base frames are fixedly connected to the bottom two sides of the same placement plate, and the bottom ends of the two threaded posts are rotatably connected to the top center of the two clamping plates. The shape of the two base frames is U-shaped, and the sides of the two clamping plates that are far apart are slidably connected to the inner walls of the two base frames.

[0009] In one possible design, each of the two base frames is fixedly connected to a fixing plate for fixing the tooling frame when it is inconvenient to clamp and fix. The corners of the two fixing plates on the opposite sides are set to be arc-shaped, and each of the two fixing plates has two mounting holes for easy installation.

[0010] In one possible design, both of the two adjustment plates are provided with rubber pads on their adjacent sides to reduce pressure damage to the lithium battery when it is secured.

[0011] In one possible design, the two clamping plates are fixedly connected to one side of each of the four sliding blocks on opposite sides. The inner walls of the two base frames are provided with sliding grooves that are adapted to the sliding blocks, and the four sliding blocks are slidably connected to the four sliding grooves respectively.

[0012] In this application, when installing the tooling frame, rotating the handle drives the threaded column to rotate, driving the clamping plate to move vertically along the sliding groove on the inner wall of the base frame. The clamping plate cooperates with the bottom of the base frame to fix the tooling frame on the mounting surface. When it is inconvenient to fix the tooling frame by clamping on the mounting surface, the fixing plate provides additional mounting points. The tooling frame is fixed by mounting holes and fasteners. The partition divides the placement plate into multiple areas to facilitate the orderly placement of lithium batteries. The placement plate has rectangular holes to facilitate heat dissipation of lithium batteries. The adjusting plate slides on the partition through the sliding groove. The motor drives the bidirectional lead screw to rotate. The bidirectional lead screw is threadedly connected to the second connecting block, driving the adjusting plate to move, so that the two adjusting plates move closer or further apart synchronously to accommodate lithium batteries of different sizes. The pressure sensor monitors the clamping force in real time. When the set value is reached, a signal is sent to stop the motor to prevent overpressure damage to the lithium battery. At the same time, the positioning rod cooperates with the first connecting block to ensure that the adjusting plate moves horizontally and avoids tilting. The limit plate on the partition prevents the adjusting mechanism from sliding excessively and avoids displacement of the lithium battery. After the lithium battery is fixed, subsequent testing and maintenance work can be carried out.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the adjustment mechanism can quickly adjust the clamping range to adapt to lithium batteries of different sizes, improving the versatility of the tooling. The pressure sensor monitors the clamping force in real time to prevent the lithium battery from being damaged by overvoltage, thus improving safety. Furthermore, the rectangular hole design improves the heat dissipation efficiency of the lithium battery and extends its service life. The threaded disassembly and assembly mechanism simplifies the installation process and reduces the difficulty of manual operation. The dual fixing method of the clamping plate and the fixing plate enhances the stability of the tooling and adapts to complex installation environments. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1

[0022] Reference Figures 1-4 A tooling rack includes a placement plate 1, an adjustment mechanism, a disassembly and assembly mechanism, and related auxiliary structures. The placement plate 1 serves as the basic load-bearing component of the tooling rack and has multiple rectangular holes 11. These rectangular holes 11 facilitate the dissipation of heat generated by the lithium battery during testing or use, preventing heat accumulation from affecting the performance of the lithium battery. The four corners of the placement plate 1 are all rounded, which not only makes it more aesthetically pleasing but also reduces the risk of damage caused by sharp corners during handling or installation. At the top of the placement plate 1, partitions 3 are fixedly connected by welding or bolts. The partitions 3 divide the placement plate 1 into multiple areas, facilitating the orderly placement of lithium battery blocks. Limiting plates 4 are fixedly connected to the front and rear sides of the four partitions 3. The limiting plates 4 serve to initially restrict the adjustment mechanism, preventing excessive sliding of the adjustment mechanism during placement.

[0023] The adjustment mechanism includes two adjusting plates 2, multiple sliding grooves 9, two pressure sensors 10, four first connecting blocks 12, two second connecting blocks 22, four first connecting plates 13, two second connecting plates 23, two positioning rods 14, a bidirectional lead screw 15, and a motor 16. Multiple sliding grooves 9 are respectively arranged on the two adjusting plates 2. The two adjusting plates 2 are slidably fitted onto multiple partitions 3 through these sliding grooves 9, allowing the adjusting plates 2 to slide along the length of the partitions 3. The tops of the two second connecting blocks 22 are fixedly connected to the center of the bottom of the two adjusting plates 2, respectively. The bottom of the second connecting blocks 22 slides through a rectangular hole 11 and is threaded onto the same bidirectional lead screw 15. The two ends of the bidirectional lead screw 15 are rotatably connected to the sides of the two second connecting plates 23 adjacent to each other via bearings. The tops of the two second connecting plates 23 are fixedly connected to the bottom of the same placement plate 1. One side of the motor 16 is fixedly connected to one side of the second connecting plate 23 via bolts, and the output shaft of the motor 16... The rotation is fixedly connected to one end of the second connecting plate 23 and the bidirectional lead screw 15. When the motor 16 starts, its output shaft drives the bidirectional lead screw 15 to rotate. Since the bidirectional lead screw 15 is threadedly connected to the two second connecting blocks 22, and the second connecting blocks 22 are restricted by the slide groove 9 and the partition 3 to only move in a straight line, the rotation of the bidirectional lead screw 15 will drive the two adjusting plates 2 to move closer or further away from each other, thereby achieving the clamping and fixing of lithium batteries of different sizes. The tops of the four first connecting blocks 12 are fixedly connected to the bottom sides of the two adjusting plates 2 respectively. The bottoms of the four first connecting blocks 12 slide through the two rectangular holes 11 respectively and slide on the two positioning rods 14 respectively. The two ends of the two positioning rods 14 are fixedly connected to one side of the four first connecting plates 13 respectively. The tops of the four first connecting plates 13 are all fixedly connected to the bottom of the same placement plate 1. The positioning rods 14 play an auxiliary positioning and stabilizing role, ensuring that the adjusting plates 2 remain horizontal during movement and do not tilt or shake.

[0024] Rubber pads 5 are provided on the side of the two adjusting plates 2 that are close to each other. The rubber pads 5 can play a buffering role when fixing the lithium battery, reducing the squeezing damage to the lithium battery. At the same time, pressure sensors 10 are provided inside the rubber pads 5 or at the position where the adjusting plates 2 contact the lithium battery. When the clamping force of the adjusting plates 2 on the lithium battery reaches the set value, the pressure sensor 10 will send a signal to control the motor 16 to stop rotating, so as to avoid excessive clamping and damage to the lithium battery.

[0025] The assembly / disassembly mechanism includes two rotating handles 17, two threaded posts 18, two base frames 6, and two clamping plates 19. The bottoms of the two rotating handles 17 are fixedly connected to the tops of the two threaded posts 18, respectively. The bottom ends of the two threaded posts 18 are threaded through the top two sides of the same placement plate 1 and the tops of the two base frames 6, respectively. The tops of the two base frames 6 are fixedly connected to the bottom two sides of the same placement plate 1, respectively. The bottom ends of the two threaded posts 18 are rotatably connected to the top center of the two clamping plates 19 via bearings. When the tooling fixture needs to be installed, the mounting surface is placed inside the base frame 6, and then the rotating handles 17 are rotated. The rotating handles 17 drive the threaded posts 18 to rotate. Since the threaded posts 18 are threadedly connected to the placement plate 1 and the base frame 6, and the shape of the two base frames 6 is set as U-shaped, the opposite sides of the two clamping plates 19 are slidably connected to the inner walls of the two base frames 6, so the rotation of the threaded posts 18 will drive the clamping plates 19 to move downward. When the clamping plates 19 move downward, they will cooperate with the bottom of the base frame 6 and be fixed on the mounting surface.

[0026] This application can be used in the field of lithium battery processing, or in other fields applicable to this application.

[0027] Example 2

[0028] refer to Figures 1-4 Based on Embodiment 1, an improved electric vehicle lithium battery tooling fixture includes:

[0029] The two clamping plates 19 are fixedly connected to one side of each of the four sliding blocks 20 on opposite sides. The inner walls of the two base frames 6 are provided with sliding grooves 21 that are adapted to the sliding blocks 20. The four sliding blocks 20 are slidably connected to the four sliding grooves 21 respectively. The cooperation between the sliding blocks 20 and the sliding grooves 21 further ensures the stability and verticality of the clamping plates 19 during movement, making the installation of the tooling frame more secure.

[0030] Two base frames 6 are fixedly connected to fixed plates 7 on opposite sides. When it is inconvenient to clamp and fix the fixed plates 7, the tooling can be fixed to other positions through the mounting holes 8 on the fixed plates 7. The corners on opposite sides of the two fixed plates 7 are all rounded to reduce damage to the outside world. The mounting holes 8 are designed to facilitate installation using bolts and other fasteners.

[0031] However, as is well known to those skilled in the art, the working principle and wiring method of pressure sensor 10 and motor 16 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. Pressure sensor 10 and motor 16 are both connected to the controller on one side of the placement plate 1 through wiring and are powered by an external power source. The model of pressure sensor 10 is set as RDF-DP06. At the same time, the materials of each component can be selected according to the usage environment and cost requirements.

[0032] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
