[0002] Steel-cased cylindrical batteries are increasingly used in the energy storage market; during the production process, steel-cased cylindrical batteries need to undergo extrusion testing to ensure their strength during subsequent use.

[0003] The clamping structure in existing cylindrical battery extrusion devices is difficult to adjust the clamping state, and can only clamp the battery in a single horizontal or vertical state. If it is necessary to change the clamping state, different clamps need to be replaced, which is cumbersome and affects the efficiency of battery extrusion detection. To address this, we propose a steel-cased cylindrical battery extrusion device. Utility Model Content

[0004] The purpose of this invention is to provide a steel-shell cylindrical battery extrusion device, which solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel-shell cylindrical battery extrusion device, comprising a housing, an electric cylinder fixedly installed at the top of the inner wall of the housing, an extrusion head fixedly installed at the output end of the electric cylinder, and clamping mechanisms provided on both sides of the bottom end of the inner wall of the housing.

[0006] The clamping mechanism includes an electric cylinder II, an arc-shaped vertical clamping plate, and a pin. The electric cylinder II is fixedly installed on the inner wall of the housing. An L-shaped horizontal clamping plate is fixedly installed at the output end of the electric cylinder II. A moving plate is slidably connected to the top of the L-shaped horizontal clamping plate. A connector is fixedly installed on the outer side of the arc-shaped vertical clamping plate. A connecting groove is opened on one side of the moving plate. The connector is inserted into the connecting groove. A pin groove is opened at the top of the connector. The pin moves through a rod hole opened at the top of the moving plate and communicates with the connecting groove, and the pin is inserted into the pin groove.

[0007] Preferably, a magnetic ring is fixedly installed on the inner wall of the rod hole that communicates with the connecting groove at the top of the movable plate. The magnetic ring is magnetically connected to the pin. By setting the magnetic ring, the stability of the pin can be improved during use.

[0008] Preferably, a limiting slider is fixedly installed at the bottom of the movable plate, a second limiting groove is opened at the top of the L-shaped transverse clamp, the limiting slider is slidably connected to the second limiting groove, a magnetic seat is embedded in the opening on the other side of the movable plate, an adsorption plate is embedded at the top of the L-shaped transverse clamp, and the magnetic seat is slidably connected to the adsorption plate. By setting the limiting slider and the second limiting groove, the movable plate can be fixedly slid on the L-shaped transverse clamp.

[0009] Preferably, both the adsorption plate and the pin are made of iron.

[0010] Preferably, a limiting plate is provided at the bottom of the inner wall of the box, a limiting slide plate is fixedly installed at the bottom of the limiting plate, a limiting groove is opened at the bottom of the inner wall of the box, the limiting slide plate is slidably connected to the limiting groove, a threaded groove is opened at the top of the limiting slide plate, a fastening screw is threadedly connected in the threaded groove, and a knob pressure head is fixedly installed at the top of the fastening screw.

[0012] This invention provides a steel-cased cylindrical battery extrusion device. This steel-cased cylindrical battery extrusion device has the following advantages:

[0013] (1) The steel-shell cylindrical battery extrusion device, by setting a clamping mechanism, can stably clamp and fix the battery in the horizontal and vertical states respectively by setting the L-shaped horizontal clamping plate and the arc-shaped vertical clamping plate, ensuring the stability of the battery in the horizontal and vertical states of the extrusion test. In addition, by setting the pin, pin groove, connector and magnetic ring, it is easy for personnel to disassemble and replace the arc-shaped vertical clamping plate with different specifications, so that batteries of different specifications can be clamped. This solves the problem that the clamping structure in the existing cylindrical battery extrusion device is difficult to adjust the clamping state, and can only clamp the battery in the horizontal or vertical state. If the clamping state needs to be changed, different clamps need to be replaced, which is more complicated and affects the efficiency of battery extrusion test.

[0014] (2) The steel-shell cylindrical battery extrusion device, through the joint cooperation of the limiting plate, the limiting slide plate, the limiting groove, the fastening screw, the threaded groove and the knob pressure head, can further limit the battery during the extrusion test, thereby further improving the stability of the battery during the test, ensuring the test accuracy, with a simple structure and strong practicality.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1:

[0025] A preferred embodiment of the steel-shell cylindrical battery extrusion device provided by this utility model is, for example... Figures 1 to 5 As shown: A steel-shell cylindrical battery extrusion device includes a housing 1, an electric cylinder 2 fixedly installed at the top of the inner wall of the housing 1, an extrusion head 3 fixedly installed at the output end of the electric cylinder 2, and clamping mechanisms 4 provided on both sides of the bottom end of the inner wall of the housing 1.

[0026] The clamping mechanism 4 includes an electric cylinder 401, an arc-shaped vertical clamping plate 408, and a pin 410. The electric cylinder 401 is fixedly installed on the inner wall of the housing 1. An L-shaped horizontal clamping plate 402 is fixedly installed at the output end of the electric cylinder 401. A moving plate 403 is slidably connected to the top of the L-shaped horizontal clamping plate 402. A connector 409 is fixedly installed on the outer side of the arc-shaped vertical clamping plate 408. A connecting groove 413 is opened on one side of the moving plate 403. The connector 409 is inserted into the connecting groove 413. A pin groove 411 is opened at the top of the connector 409. The pin 410 moves through the rod hole opened at the top of the moving plate 403 and communicates with the connecting groove 413, and the pin 410 is inserted into the pin groove 411.

[0027] Specifically, in the above technical solution, when the steel-cased cylindrical battery extrusion device needs to perform an extrusion test on the side of the battery, the battery can be placed horizontally inside the bottom of the housing 1, with both ends of the battery positioned between two L-shaped horizontal clamps 402. Then, the second electric cylinder 401 is activated, which moves the L-shaped horizontal clamps 402 closer to the battery, ultimately clamping the battery in its horizontal position. Then, the first electric cylinder 2 is activated, which moves the extrusion head 3 downward, allowing the extrusion head 3 to perform an extrusion test on the side of the battery. When extrusion is required on one end of the battery... During testing, the battery is placed vertically at the bottom of the box 1. Then, the magnetic base 404 is closed, and the moving plate 403 is pushed, causing it to move the arc-shaped vertical clamping plate 408 towards the battery via the connector 409. The arc-shaped vertical clamping plate 408 extends beyond the L-shaped horizontal clamping plate 402. Then, the magnetic base 404 is opened to limit and fix the moving plate 403, and the pin 410 is pulled upward to disengage from the pin groove 411, so that the pin 410 no longer limits and fixes the connector 409. At this point, the arc-shaped vertical clamping plate 408 is disassembled and replaced with the battery. After confirming the specifications, the second electric cylinder 401 can be restarted. The second electric cylinder 401 will drive the moving plate 403 to move through the L-shaped horizontal clamping plate 402. The moving plate 403 will then drive the arc-shaped vertical clamping plate 408 to move towards the battery through the connector 409. Ultimately, the arc-shaped vertical clamping plate 408 will wrap and clamp the battery in a vertical position. Then, the first electric cylinder 2 can be started, allowing the compression head 3 to perform a compression test on one end of the battery. Through the above structure, the L-shaped horizontal clamping plate 402 and the arc-shaped vertical clamping plate 408 can stably clamp and fix the battery in both horizontal and vertical positions, respectively. This design ensures the stability of the battery during compression testing in both horizontal and vertical states. Furthermore, the pin 410, pin groove 411, connector 409, and magnetic ring 412 facilitate the disassembly and replacement of the arc-shaped vertical clamping plate 408 with different specifications, allowing for clamping of batteries of varying sizes. This solves the problem in existing cylindrical battery compression devices where the clamping structure is difficult to adjust, only allowing clamping in either a horizontal or vertical position. Changing the clamping position requires replacing different clamps, making the operation cumbersome and affecting the efficiency of battery compression testing.

[0028] Furthermore, a magnetic ring 412 is fixedly installed on the inner wall of the rod hole opened at the top of the movable plate 403 and the connecting groove 413, and the magnetic ring 412 is magnetically connected to the pin 410.

[0029] By incorporating a magnetic ring 412, the stability of the pin 410 during use can be improved.

[0030] Furthermore, a limiting slider 406 is fixedly installed at the bottom of the movable plate 403, and a limiting groove 407 is opened at the top of the L-shaped transverse clamping plate 402. The limiting slider 406 is slidably connected to the limiting groove 407. A magnetic seat 404 is embedded in the opening on the other side of the movable plate 403, and an adsorption plate 405 is embedded at the top of the L-shaped transverse clamping plate 402. The magnetic seat 404 is slidably connected to the adsorption plate 405.

[0031] By setting the limiting slider 406 and the limiting groove 407, the moving plate 403 can be fixed and slid on the L-shaped transverse clamp 402.

[0032] Furthermore, both the adsorption plate 405 and the pin 410 are made of iron.

[0033] Furthermore, a door 10 is hinged to the front of the box body 1, and a support block 11 is fixedly installed at the bottom of the box body 1.

[0034] Among them, the support block 11 can provide support for the box 1.

[0035] Example 2:

[0036] Based on Embodiment 1, a preferred embodiment of the steel-cased cylindrical battery extrusion device provided by this utility model is, for example... Figures 1 to 5 As shown: A limit plate 5 is provided at the bottom of the inner wall of the box 1. A limit slide plate 6 is fixedly installed at the bottom of the limit plate 5. A limit groove 7 is opened at the bottom of the inner wall of the box 1. The limit slide plate 6 is slidably connected to the limit groove 7. A threaded groove 9 is opened at the top of the limit slide plate 6. A fastening screw 8 is threadedly connected in the threaded groove 9. A knob pressure head 12 is fixedly installed at the top of the fastening screw 8.

[0037] Specifically, in the above technical solution, when the battery is clamped in both horizontal and vertical positions, the movable limiting plate 5 can be moved closer to the battery so that the limiting plate 5 contacts the outer wall of the battery. Then, the knob pressure head 12 is rotated, causing the knob pressure head 12 to drive the fastening screw 8 to rotate into the threaded groove 9, so that the knob pressure head 12 compresses the bottom of the inner wall of the housing 1, thereby fixing the position of the limiting plate 5. Through the above structure, the limiting plate 5 can further limit the battery during the compression test, thereby further improving the stability of the battery during the test, ensuring the test accuracy, and the structure is simple and highly practical.

[0038] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
