Description

Technical Field

[0001] This utility model belongs to the technical field of battery box side beams, and specifically relates to a positioning fixture for battery box side beams. Background Technique

[0002] In today's new energy field, the rapid development of battery technology has put forward higher requirements for the manufacturing of battery boxes. As an important structure for protecting battery packs, the quality and performance of battery boxes directly affect the safety, stability, and service life of battery systems. Among them, the side beam, as a key component of the battery box, its precise positioning and firm fixation are crucial during the manufacturing process.

[0003] With the continuous progress of battery technology and the diversification of market demands, the design of battery boxes has become increasingly complex, and the shape of side beams is no longer limited to traditional regular geometric forms. The emergence of irregular side beams has become the norm. The structural characteristics of such irregular side beams have posed great challenges to positioning and fixation during the manufacturing process.

[0004] In previous manufacturing processes, the side beam positioning fixtures used had many deficiencies. Some common fixtures only provided simple fixing methods and lacked adaptability to irregular shapes. They might only support and clamp the side beam through a few fixed points, unable to fully conform to the irregular surface of the side beam, resulting in easy position deviation of the side beam during processing or assembly. Such deviation not only affects the overall dimensional accuracy of the battery box but may also pose safety hazards during subsequent use.

[0005] In addition, when adjusting the vertical position of the side beam, traditional fixtures usually adopt a relatively rough method and are difficult to achieve precise and fine adjustment. This makes the side beam unable to reach the optimal processing or assembly height, thereby affecting the quality and performance of the product.

[0006] At the same time, due to the lack of an effective adaptive mechanism, when fixing the side beam, traditional fixtures are prone to uneven distribution of the pressing force. Excessive local pressing force may cause the side beam to deform or even be damaged, while insufficient pressing force in some places cannot ensure the firm fixation of the side beam, thus affecting the structural strength and reliability of the entire battery box.

[0007] Therefore, we have proposed a positioning fixture for battery box side beams, which can precisely adjust, stably support, and uniformly and reliably fix irregular side beams in the horizontal and vertical directions, thereby providing strong guarantee for the high-quality production of battery boxes. Content of the Utility Model

[0008] The purpose of this utility model is to provide a positioning fixture for the side beam of a battery box, which can accurately adjust, stably support, and uniformly and reliably fix the irregular side beam in the horizontal and vertical directions, thereby providing a strong guarantee for the high-quality production of the battery box.

[0009] The technical solution adopted by this utility model is as follows:

[0010] A positioning fixture for the side beam of a battery box includes a workbench. Two groups of first threaded holes and one group of second threaded holes are provided on the workbench. First threaded rods are arranged inside both groups of the first threaded holes. A telescopic component is hinged to the top of the first threaded rod. A pressing plate is arranged on the telescopic component. A second threaded rod is arranged inside the second threaded hole. A sliding plate is arranged on the top of the second threaded rod. Multiple groups of through holes are provided on the sliding plate. An active rod is arranged in each through hole. A support disc is arranged at the top of the active rod in a rolling manner. A limiting disc is arranged at the bottom of the active rod. And a spring is sleeved on the active rod and is located between the support disc and the sliding plate.

[0011] The side beam is located on the top of the support disc.

[0012] Furthermore, a first anti-slip surface is arranged at the bottom of the pressing plate.

[0013] Furthermore, a second anti-slip surface is arranged at the top of the support disc.

[0014] Furthermore, multiple groups of symmetric limiting blocks are arranged on the workbench. A sliding groove is formed between two of the limiting blocks. A sliding block connected to the sliding plate is arranged inside the sliding groove.

[0015] Furthermore, the sliding block matches the sliding groove.

[0016] Furthermore, the telescopic component includes an electric telescopic rod arranged on the first threaded rod. The telescopic end of the electric telescopic rod is connected to the pressing plate.

[0017] The technical effects achieved by this utility model are:

[0018] When it is necessary to position and fix the irregular side beam of the battery box body, first place the side beam on the sliding plate. The support discs at the tops of multiple groups of movable rods evenly distributed on the sliding plate are in contact with the lower surface of the side beam. Due to the irregular shape of the side beam, the support discs at different positions change angles during the rolling of the movable rods and will move up and down adaptively according to the undulations and concavities of the side beam. The movable rods can slide smoothly in the through holes on the sliding plate, and at the same time, the springs sleeved on the movable rods are compressed or stretched. The elastic action of the springs enables each support disc to closely fit the lower surface of the side beam, providing uniform and stable supporting force to ensure that the side beam has a certain stability when initially placed. Then, rotate the second threaded rod in the second threaded hole. Under the action of the thread, the second threaded rod rises or falls. Since the top of the second threaded rod is connected to the sliding plate, the sliding plate will move in the vertical direction as the second threaded rod rotates, thereby precisely adjusting the position of the side beam in the vertical direction to make it reach the optimal processing or assembly height. Next, rotate the first threaded rods in the two groups of first threaded holes. When the first threaded rods rotate, due to the thread fit with the first threaded holes, they will rise or fall along the axis direction of the threaded holes. The telescopic components hinged to the tops of the first threaded rods will move accordingly, driving the pressing plate closer to the side beam. The telescopic components can be flexibly adjusted in terms of telescopic according to the shape and position of the side beam to ensure that the pressing plate can accurately contact the upper surface of the side beam. After the pressing plate contacts the side beam, continue to rotate the first threaded rod to make the pressing plate apply sufficient pressure to the side beam, tightly pressing and fixing the side beam in the horizontal direction. During the entire fixing process, due to the coordinated action of multiple groups of support discs and the pressing plate, the side beam is accurately positioned and reliably fixed in both the horizontal and vertical directions. This device can precisely adjust, stably support, and uniformly and reliably fix the irregular side beam in the horizontal and vertical directions, thus providing a strong guarantee for the high-quality production of the battery box body.

[0026] In order to make the purpose and advantages of the present utility model clearer, the present utility model will be specifically described below in conjunction with embodiments. It should be understood that the following text only describes one or several specific implementation manners of the present utility model, and does not strictly limit the scope of protection of the specific claims of the present utility model.

[0027] As Figures 1-5 shown, the technical solution adopted by the present utility model is specifically as follows: A positioning fixture for the side beam of a battery box body, including a workbench 1, two groups of first threaded holes 2 and a group of second threaded holes 3 are opened on the workbench 1. First threaded rods 4 are arranged inside both groups of first threaded holes 2. A telescopic assembly is hinged to the top of the first threaded rod 4. A pressing plate 5 is arranged on the telescopic assembly. A second threaded rod 6 is arranged inside the second threaded hole 3. A sliding plate 7 is arranged on the top of the second threaded rod 6. Multiple through holes are opened on the sliding plate 7. Each through hole is provided with a movable rod 8. A support disc 9 is arranged at the top of the movable rod 8 in a rolling manner. A limit disc is arranged at the bottom of the movable rod 8. And a spring 10 is sleeved on the movable rod 8, and the position of the spring 10 is between the support disc 9 and the sliding plate 7;

[0028] The side beam 15 is located on the top of the support disc 9.

[0029] Its working principle is as follows: When it is necessary to position and fix the irregular side beam 15 of the battery box, first place the side beam 15 on the sliding plate 7. The support disks 9 at the tops of multiple groups of movable rods 8 evenly distributed on the sliding plate 7 are in contact with the lower surface of the side beam 15. Due to the irregular shape of the side beam 15, the support disks 9 at different positions change angles as the movable rods 8 roll, and will move up and down adaptively according to the undulations and concavities of the side beam 15. The movable rods 8 can slide smoothly in the through holes on the sliding plate 7, and at the same time, the springs 10 sleeved on the movable rods 8 are compressed or stretched. The elastic action of the springs 10 enables each support disk 9 to closely fit the lower surface of the side beam 15, providing uniform and stable supporting force to ensure that the side beam 15 has a certain stability when initially placed. Then, by rotating the second threaded rod 6 in the second threaded hole 3, the second threaded rod 6 rises or falls under the action of the thread. Since the top of the second threaded rod 6 is connected to the sliding plate 7, the sliding plate 7 will move in the vertical direction as the second threaded rod 6 rotates, thereby precisely adjusting the position of the side beam 15 in the vertical direction to make it reach the optimal processing or assembly height. Next, rotate the first threaded rods 4 in the two groups of first threaded holes 2. When the first threaded rods 4 rotate, due to the thread fit with the first threaded holes 2, they will rise or fall along the axis direction of the threaded holes. The telescopic components hinged to the tops of the first threaded rods 4 will move accordingly, driving the pressing plate 5 closer to the side beam 15. The telescopic components can be flexibly adjusted in terms of telescopic according to the shape and position of the side beam 15 to ensure that the pressing plate 5 can accurately contact the upper surface of the side beam 15. After the pressing plate 5 contacts the side beam 15, continue to rotate the first threaded rod 4 to make the pressing plate 5 apply sufficient pressure to the side beam 15, tightly pressing and fixing the side beam 15 in the horizontal direction. During the entire fixing process, due to the coordinated action of multiple groups of support disks 9 and the pressing plate 5, the side beam 15 is accurately positioned and reliably fixed in both the horizontal and vertical directions. The presence of the springs 10 can not only adapt to the irregular shape of the side beam 15 but also prevent damage to the side beam 15 caused by excessive pressing force. Such a design can meet the positioning requirements of side beams 15 with different shapes and sizes, providing stable and accurate working conditions for subsequent related operations. This device can precisely adjust, stably support, and uniformly and reliably fix the irregular side beam 15 in both the horizontal and vertical directions, thus providing strong guarantee for the high-quality production of the battery box.

[0030] Among them, when the side beam 15 is placed on the support plate 9, the gravity will drive the movable rod 8 in contact with it to move downward. Since the movable rod 8 can slide smoothly in the through hole on the sliding plate 7, this also provides space for the possible slight movement or adjustment of the side beam 15 during the placement process, enabling multiple support plates 9 to form a groove body with the same shape as the side beam 15, making the fixture more flexible to adapt to the actual shape and position of the side beam 15. Therefore, when the side beam 15 is placed on the support plate 9, due to the interaction of gravity, the spring 10 and the movable rod 8, the fixture can achieve self-adaptive support and stable fixing effect.

[0031] At the same time, during the process of the telescopic assembly driving the pressing plate 5 to fix the side beam 15, the side beam 15 will drive the movable rod 8 that has already contacted it to continue to move downward due to its own gravity or external pressure, thereby squeezing the spring 10. During this process, the spring 10 will be compressed to its maximum deformation amount, thus storing the corresponding elastic potential energy. When the side beam 15 is fixed at this position, since the spring 10 has reached its maximum compression amount, it can provide a stable supporting force and reaction force to ensure that the side beam 15 will not undergo elastic movement or displacement during drilling or other operations, guaranteeing the accuracy and stability of processing or assembly.

[0032] It should be noted that the function of the second threaded rod 6 is to drive the sliding plate 7 to adjust the height of the side beam 15, so as to precisely adjust the position of the side beam 15 in the vertical direction to reach the optimal processing or assembly height.

[0033] The function of the first threaded rod 4 is: to adjust the height of the telescopic assembly, so that the pressing plate 5 can be fitted and fixed with the side beam 15.

[0034] Furthermore, the telescopic assembly is hinged to the threaded rod. When the pressing plate 5 is pressed, the angle of the pressing plate 5 can be adjusted, so that the pressing plate 5 fits the irregular surface of the side beam 15, improving the fixing effect.

[0035] A first anti-slip surface is provided at the bottom of the pressing plate 5. Through the first anti-slip surface, the side beam 15 can be prevented from moving during fixation.

[0036] A second anti-slip surface is provided at the top of the support plate 9. Through the second anti-slip surface, movement during support can be prevented.

[0037] Multiple groups of symmetric limiting blocks 11 are provided on the workbench 1. A chute 12 is opened between the two limiting blocks 11, and a slider 13 connected to the sliding plate 7 is arranged inside the chute 12.

[0038] When the sliding plate 7 needs to move, the slider 13 connected to it will slide inside the chute 12. Since the chute 12 is formed by symmetric limiting blocks 11, it can effectively limit the moving direction of the slider 13 (and the sliding plate 7 connected thereto), ensuring that the sliding plate 7 can only move along a predetermined trajectory.

[0039] In addition, the cooperation between the chute 12 and the slider 13 can also provide a stable supporting effect, preventing the sliding plate 7 from shaking or shifting during movement. In this way, when punching or other operations need to be performed on the side beam 15, the sliding plate 7 (and the side beam 15 thereon) can be maintained in a stable and accurate position, thus ensuring the precision and quality of processing or assembly.

[0040] The telescopic assembly includes an electric telescopic rod 14 provided on the first threaded rod 4. The telescopic end of the electric telescopic rod 14 is connected to the pressing plate 5, and the pressing plate 5 is driven to move through the electric telescopic rod 14, so as to be fixed.

[0041] The working principle of this utility model is as follows: When it is necessary to position and fix the irregular side beam 15 of the battery box body, first place the side beam 15 on the sliding plate 7. The support disks 9 at the tops of multiple groups of movable rods 8 evenly distributed on the sliding plate 7 are in contact with the lower surface of the side beam 15. Due to the irregular shape of the side beam 15, the support disks 9 at different positions change their angles as the movable rods 8 roll, and will move up and down adaptively according to the undulations and concavities of the side beam 15. The movable rods 8 can slide smoothly in the through holes on the sliding plate 7, and at the same time, the springs 10 sleeved on the movable rods 8 are compressed or stretched. The elastic effect of the springs 10 enables each support disk 9 to closely fit the lower surface of the side beam 15, providing uniform and stable supporting force to ensure that the side beam 15 has a certain stability when initially placed. Then, rotate the second threaded rod 6 in the second threaded hole 3. Under the action of the thread, the second threaded rod 6 rises or falls. Since the top of the second threaded rod 6 is connected to the sliding plate 7, the sliding plate 7 will move in the vertical direction as the second threaded rod 6 rotates, so as to precisely adjust the position of the side beam 15 in the vertical direction to make it reach the optimal processing or assembly height. Next, rotate the first threaded rods 4 in the two groups of first threaded holes 2. When the first threaded rods 4 rotate, due to the thread fit with the first threaded holes 2, they will rise or fall along the axis direction of the threaded holes. The telescopic components hinged to the tops of the first threaded rods 4 will move accordingly, driving the pressing plate 5 closer to the side beam 15. The telescopic components can be flexibly adjusted in terms of telescoping according to the shape and position of the side beam 15 to ensure that the pressing plate 5 can accurately contact the upper surface of the side beam 15. After the pressing plate 5 contacts the side beam 15, continue to rotate the first threaded rod 4 to make the pressing plate 5 apply sufficient pressure to the side beam 15, tightly pressing and fixing the side beam 15 in the horizontal direction. During the entire fixing process, due to the cooperative action of multiple groups of support disks 9 and the pressing plate 5, the side beam 15 is accurately positioned and reliably fixed in both the horizontal and vertical directions. The presence of the springs 10 can not only adapt to the irregular shape of the side beam 15, but also play a buffering role during the fixing process to prevent damage to the side beam 15 caused by excessive pressing force. Such a design can meet the positioning requirements of side beams 15 with different shapes and sizes, providing stable and accurate working conditions for subsequent related operations.

[0042] The above are only the preferred embodiments of this utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
