Description

Technical Field

[0001] This utility model belongs to the technical field of heavy object impact devices, and in particular relates to a heavy object impact device for battery testing. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes to generate an electric current. Using batteries as an energy source provides a stable voltage, stable current, and a long-term stable power supply, with minimal susceptibility to external influences. Batteries play a significant role in various aspects of modern life. During battery production, multiple performance indicators need to be tested. Impact resistance is one such indicator, achieved by impacting the battery with a heavy object and observing changes in voltage and other values, as well as whether the battery will explode or catch fire.

[0003] Existing impact devices have certain drawbacks. First, it is not convenient to adjust the height and weight of existing impact devices. Second, it is not convenient to pull the impact weight up, which requires manual handling of the weight during each impact test, thus having a certain impact. Therefore, there is an urgent need for a heavy impact device for battery testing to solve the above problems. Utility Model Content

[0004] To solve the above problems, this utility model provides a heavy object impact device for battery testing, which is achieved through the following technical solution.

[0005] A heavy object impact device for battery testing includes a base and a battery component A. A gantry frame is fixedly connected to the top of the base. A winding machine is installed on the gantry frame. The winding machine is connected to a steel wire rope through a rope winding wheel. A connecting rod is fixedly connected to one end of the steel wire rope. A lifting seat is movably connected to the gantry frame.

[0006] The top of the lifting seat is fixedly connected to a hanger and a positioning column. A gravity plate is provided on the positioning column. An installation port is opened on the top of the hanger. A conical impact block is fixedly connected to the bottom of the lifting seat. An infrared detection hole is opened at the bottom of the conical impact block. An infrared rangefinder is fixedly connected inside the conical impact block at the position corresponding to the infrared detection hole.

[0007] A positioning seat is fixedly connected to the top of the base, and hydraulic cylinders are connected through both sides of the positioning seat. A clamping plate is fixedly connected to the telescopic end of the hydraulic cylinder.

[0008] Furthermore, the connecting rod is connected to the hanger through the mounting port. A servo motor is fixedly connected to the bottom end of the connecting rod. The lead screw fixed to the output shaft of the servo motor is rotatably engaged with the connecting rod. A movable block is movably connected to the lead screw, and the lead screw and the movable block are threadedly engaged. Two support rods are rotatably connected to the connecting rod. A rotating arm is rotatably connected to the support rod, and one end of the rotating arm is rotatably connected to the movable block. A roller is rotatably connected to one end of the support rod.

[0009] Furthermore, the rollers are pressed against the inside of the hanger.

[0010] Furthermore, the gravity disk is provided with four disks, the weight of the four disks gradually increases from top to bottom, and the positioning pin is threadedly engaged with the gravity disk.

[0011] Furthermore, the conical impact block is located directly above battery component A.

[0012] Furthermore, the battery component A is disposed inside the positioning seat, and the two clamping plates are respectively clamped on both sides of the battery component A.

[0013] The beneficial effects of this utility model are as follows: During operation, the battery component A is first placed into the positioning seat for clamping and fixing. Then, the winding machine is turned on to wind and unwind the wire rope. The connecting rod connected to the wire rope can pull the lifting seat connected to the hanger to rise and fall. The lifting seat drives the connected conical impact block to rise and fall. When the conical impact block rises to the designated height, the driving connecting rod disengages from the support of the hanger, so the lifting seat falls freely on the gantry. Then, the conical impact block fixed on the lifting seat impacts the battery component A directly below, thereby enabling impact detection of the fixed battery component A. The infrared rangefinder installed on the conical impact block can measure the distance to the battery component A, which is convenient for adjusting and controlling the impact spacing. At the same time, the four conical impact blocks installed on the lifting seat can be easily disassembled and assembled, thereby adjusting the weight of the impact device. The structure is reasonable, easy to adjust, and can pull heavy objects up, making it easy to reuse and convenient to use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] like Figure 1-3 As shown, the present invention has the following specific embodiments.

[0028] Example:

[0029] A heavy object impact device for battery testing includes a base 1 and a battery component A. A gantry frame 11 is fixedly connected to the top of the base 1. A winding machine 7 is installed on the gantry frame 11. A wire rope 71 is connected to the winding machine 7 through a rope winding wheel. A connecting rod 6 is fixedly connected to one end of the wire rope 71. A lifting seat 2 is movably connected to the gantry frame 11.

[0030] The top of the lifting seat 2 is fixedly connected to a hanger 21 and a positioning column 23. A gravity plate 3 is installed on the top of the positioning column 23. An installation port 22 is opened on the top of the hanger 21. A conical impact block 4 is fixedly connected to the bottom of the lifting seat 2. An infrared detection hole 41 is opened on the bottom of the conical impact block 4. An infrared rangefinder 42 is fixedly connected inside the conical impact block 4 at the position corresponding to the infrared detection hole 41.

[0031] A positioning seat 5 is fixedly connected to the top of the base 1. Hydraulic cylinders 51 are connected through both sides of the positioning seat 5. A clamping plate 52 is fixedly connected to the telescopic end of the hydraulic cylinder 51.

[0032] Specifically, the connecting rod 6 is connected to the hanger 21 through the mounting port 22. A servo motor 61 is fixedly connected to the bottom end of the connecting rod 6. The lead screw 62, which is fixed to the output shaft of the servo motor 61, is rotatably engaged with the connecting rod 6. A movable block 65 is movably connected to the lead screw 62, and the lead screw 62 and the movable block 65 are threaded together. Two support rods 63 are rotatably connected to the connecting rod 6. A rotating arm 64 is rotatably connected to the support rod 63, and one end of the rotating arm 64 is rotatably connected to the movable block 65. A roller 631 is rotatably connected to one end of the support rod 63. By opening... Servo motor 61 can drive lead screw 62 to rotate, lead screw 62 can drive threaded movable block 65 to rise and fall, movable block 65 can pull rotating arm 64 to move, movable rotating arm 64 can pull support rod 63 to rotate on connecting rod 6. When support rod 63 rotates into the inside of connecting rod 6, connecting rod 6 can pass through mounting port 22. When support rod 63 rotates to form a 45° angle with connecting rod 6, support rod 63 can be supported on hanger 21, so that connecting rod 6 can pull the supported hanger 21 to rise and fall.

[0033] Specifically, the roller 631 is pressed and supported inside the hanger 21, so that the movable support rod 63 can slide on the hanger 21 by means of the roller 631.

[0034] Specifically, there are four gravity disks 3, and the weight of the four gravity disks 3 gradually increases from top to bottom. The positioning post 23 is threaded with the gravity disk 3, which makes it easy to install and remove the gravity disk 3 on the positioning post 23, thereby facilitating the adjustment of the weight of the impact test.

[0035] Specifically, the conical impact block 4 is located directly above the battery component A, enabling the conical impact block 4 to impact the battery component A from directly above.

[0036] Specifically, battery component A is located inside the positioning seat 5, and two clamping plates 52 are respectively clamped on both sides of battery component A, which can fix battery component A inside the positioning seat 5 for impact testing.

[0037] The working principle of this utility model:

[0038] When using the device, first place the battery component A into the positioning seat 5 for clamping and fixing. Then, turn on the winding machine 7 to wind up and unwind the wire rope 71. The connecting rod 6 connected to the wire rope 71 can pull the lifting seat 2 connected to the hanger 21 to rise and fall. The lifting seat 2 drives the connected conical impact block 4 to rise and fall. When the conical impact block 4 rises to the specified height, the driving connecting rod 6 is disengaged from the support of the hanger 21, so the lifting seat 2 falls freely on the gantry 11. Then, the conical impact block 4 fixed on the lifting seat 2 impacts the battery component A directly below, thus enabling impact detection of the fixed battery component A. The infrared rangefinder 42 set on the conical impact block 4 can measure the distance to the battery component A, which is convenient for adjusting and controlling the impact spacing. At the same time, the four conical impact blocks 4 set on the lifting seat 2 can be easily disassembled and assembled, so as to adjust the weight of the impact device. The structure is reasonable, easy to adjust, and can pull heavy objects up. It is easy to reuse and convenient to use.
