Description

Technical Field

[0001] This utility model relates to the field of battery casing processing technology, and specifically to a strength testing device for processing plastic battery casings. Background Technology

[0002] The battery casing is a crucial component of a battery, primarily serving to protect its internal structure and prevent external impacts and corrosion. Common battery casing materials include steel, aluminum, and plastic. Steel and aluminum are widely used in the manufacture of power battery casings due to their excellent strength and toughness, while plastic materials are used in certain specific applications due to their lightweight and ease of processing.

[0003] During the manufacturing process of plastic battery casings, it is necessary to test their maximum tensile strength. The results of the battery casing tensile strength test provide important reference for the design and manufacturing of the battery casing. By understanding the mechanical properties of materials, such as tensile strength, the structural design of the battery casing can be optimized, and the strength and toughness of the battery casing can be improved, thereby ensuring better safety and reliability of the battery in practical applications.

[0004] The utility model application with application number CN202123089069.0 provides a stretching device for battery casing production with protective function, including a first station plate, a high-strength vertical lead screw, a left L-shaped clamping block, an adjusting side plate, a vertical slider, a distance scale, a high-strength horizontal lead screw, a horizontal limiting sleeve, a small geared motor, and a support platform. The first station plate is welded to the right side of the upper surface of the worktable, and a high-strength vertical lead screw is set on the upper side inside the first station plate. The support platform is welded to the lower side of the left end of the first station plate. The left L-shaped clamping block is set on the right end of the adjusting side plate, and a high-strength horizontal lead screw is installed on the left end of the small geared motor. This design solves the problem that the original stretching device for battery casings does not have adjustable limiting capability. This utility model has a reasonable structure, has adjustable limiting capability, facilitates stretching tests on battery casings of different specifications, and has strong practicality.

[0005] The aforementioned patent clamps the upper surface of the battery casing and stops testing when the battery casing is pulled open and cracked. However, during the battery casing test, it is impossible to guarantee that the upper and lower ends of the battery casing are on the same horizontal plane with the same tension, resulting in inaccurate test results.

[0006] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0007] The purpose of this invention is to provide a strength testing device for processing plastic battery casings that can effectively solve the above-mentioned technical problems.

[0008] To achieve the purpose of this utility model, the following technical solution is adopted:

[0009] A strength testing device for processing plastic battery casings includes: a clamping assembly, a driving assembly, and a limiting assembly;

[0010] The limiting component consists of a base and a retainer; the base includes a fixed seat and a slider that is slidably installed in the fixed seat.

[0011] The fixture includes a fixed shell, a third cylinder fixedly installed inside the fixed shell, a clamping plate fixedly installed at the output end of the third cylinder, a crank rod rotatably installed at the bottom end of the clamping plate, and a rotating plate rotatably installed at the other end of the crank rod. Four identical clamping plates and crank rods are arranged in a circular array around the fixed shell. The slider is fixedly connected to the fixed shell.

[0012] Furthermore, the base is provided with a sliding groove to facilitate the movement of the slider, and the top of the fixed shell is also provided with a guide groove to guide the movement of the clamping plate.

[0013] Furthermore, the clamping assembly includes a rotating block, a bidirectional screw fixedly mounted on the rotating block, a clamping plate threaded to the bidirectional screw, and a vertical detector fixedly mounted on the side of the rotating block. The bidirectional screw is rotatably mounted on the mounting housing, and the bidirectional screw has two sets of reverse threads.

[0014] Furthermore, the drive assembly consists of a second cylinder and a sliding disc; the output end of the second cylinder is fixedly connected to the sliding disc.

[0015] Compared with the prior art, this utility model has the following beneficial effects: This utility model provides a strength testing device for processing plastic battery casings. When the third cylinder receives a control signal, its output end pushes the clamping plate to move. The movement of the clamping plate is transmitted to the rotating plate through the rotation of the crank, causing the rotating plate to perform a corresponding rotational action. Since four identical clamping plates, cranks, and rotating plates are arranged in a circular array around the fixed shell, when one clamping mechanism moves, the other three sets will move synchronously, achieving stable clamping and limiting of the bottom end of the battery casing.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

When a mechanism is referred to as being "fixed to" another mechanism, it can be directly on the other mechanism or there may be an intervening mechanism. When a mechanism is considered to be "connected" to another mechanism, it can be directly connected to the other mechanism or there may be an intervening mechanism at the same time. When a mechanism is considered to be "set on" another mechanism, it can be directly set on the other mechanism or there may be an intervening mechanism at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] like Figures 1 to 5As shown, a strength testing device for processing plastic battery casings includes: a clamping component 2, a driving component 4, and a limiting component 5.

[0026] During the manufacturing process of plastic battery casings, it is necessary to test their maximum tensile strength. The results of the tensile strength test provide important reference for the design and manufacturing of the battery casing. By understanding the mechanical properties of materials, such as tensile strength, the structural design of the battery casing can be optimized, and the strength and toughness of the casing can be improved, thereby ensuring better safety and reliability of the battery in practical applications.

[0027] In the process of testing the tensile strength that the battery casing can withstand, the upper and lower ends of the battery casing need to be clamped at the same time, and then stretched to test the maximum strength that the battery casing can withstand.

[0028] The clamping assembly 2 includes a rotating block 21, a bidirectional screw 23 fixedly mounted on the rotating block 21, a clamping plate 22 threadedly connected to the bidirectional screw 23, and a vertical detector 24 fixedly mounted on the side of the rotating block 21. The bidirectional screw 23 is rotatably mounted on the mounting shell, and the bidirectional screw 23 is provided with two sets of reverse threads. When the bidirectional screw 23 rotates, the two sets of reverse threads drive the two clamping plates 22 to move in opposite directions along the thread direction, clamping the upper end of the battery and ensuring that the upper end of the battery is at the center line position of the bidirectional screw 23.

[0029] As a supplement: During the clamping process, the moving speed and clamping force of the clamping plate 22 can be controlled by adjusting the rotation speed and direction of the bidirectional screw 23, thereby adapting to different objects and clamping requirements. At the same time, the vertical detector 24 is fixedly installed on the side of the rotating block 21 to detect whether the clamping plate 22 and the battery case remain perpendicular, ensuring the accuracy of the results measured during the tensile test.

[0030] The battery casing is subjected to tensile strength testing by raising and lowering the entire clamping assembly 2 by installing the first cylinder 1.

[0031] The drive assembly 4 consists of a second cylinder 41 and a sliding disk 42. The output end of the second cylinder 41 is fixedly connected to the sliding disk 42. Since the output end of the second cylinder 41 is fixedly connected to the sliding disk 42, the sliding disk 42 will move with the movement of the cylinder output end. This can be used to adjust the position of the sliding disk 42, thereby realizing the back-and-forth movement of the bottom end of the battery case, facilitating the adjustment of the battery case position so that the horizontal position of its bottom end and top end can be kept consistent.

[0032] The limiting component 5 consists of a base 51 and a fixing device 52. The fixing device 52 includes a fixed shell 521, a third cylinder 522 fixedly installed inside the fixed shell 521, a clamping plate 523 fixedly installed at the output end of the third cylinder 522, a crank 524 rotatably installed at the bottom end of the clamping plate 523, and a rotating plate 525 rotatably installed at the other end of the crank 524. Four identical clamping plates 523 and cranks 524 are arranged in a circular array around the fixed shell 521. When the third cylinder 522 receives a control signal, its output end pushes the clamping plate 523 to move. The movement of the clamping plate 523 is transmitted to the rotating plate 525 through the rotation of the crank 524, causing the rotating plate 525 to perform a corresponding rotation action. Since four identical clamping plates 523, cranks 524 and rotating plates 525 are arranged in a circular array around the fixed shell 521, when one clamping mechanism moves, the other three will move synchronously to achieve stable clamping and limiting of the bottom of the battery shell.

[0033] The base 51 comprises a fixed seat 511 and a slider 512 slidably mounted within the fixed seat 511. The base 51 has a groove for facilitating the movement of the slider 512, and the top of the fixed housing 521 also has a guide groove for the movement of the guide clamping plate 523. The slider 512 is fixedly connected to the fixed housing 521. To facilitate the movement of the slider 512, the groove on the base 51 ensures that the slider 512 can slide smoothly within it, and also restricts the direction of movement of the slider 512, allowing it to move only along a predetermined path, thereby improving the slider 512's stability. The movement accuracy of cylinder 12 is achieved, and the movement of clamping plate 523 is guided by guide groove. When the third cylinder 522 drives clamping plate 523 to move, guide groove can ensure that clamping plate 523 moves along a predetermined direction, thereby achieving precise clamping of the bottom end of battery case. At the same time, the slider 512 drives the fixed shell 521 and its internal clamping mechanism to move synchronously, realizing dynamic clamping of fixture 52, so as to keep the bottom end and top end of battery case always on the axis output by the first cylinder 1 during the test, ensuring the accuracy of the data obtained from battery case test.

[0034] Working principle:

[0035] When the bidirectional screw 23 rotates, the two sets of reverse threads drive the two clamping plates 22 to move in opposite directions along the thread direction, clamping the upper end of the battery and ensuring that the upper end of the battery is at the center line of the bidirectional screw 23. The output end of the second cylinder 41 is fixedly connected to the sliding plate 42, so the sliding plate 42 will move with the movement of the cylinder output end. When the third cylinder 522 receives a control signal, its output end will push the clamping plate 523 to move. The movement of the clamping plate 523 is transmitted to the rotating plate 525 through the rotation of the crank 524, causing the rotating plate 525 to perform a corresponding rotation action. Since four sets of identical clamping plates 523, cranks 524 and rotating plates 525 are arranged in a circular array around the fixed shell 521, when one set of clamping mechanisms moves, the other three sets will also move synchronously, realizing stable clamping and limiting of the bottom end of the battery shell.
