Description

Technical Field

[0001] This utility model relates to the field of impact test technology, and in particular to impact test fixtures. Background Technology

[0002] With the booming development of modern manufacturing, various products, especially those involving safety and susceptible to impact damage (such as electronic products, automotive parts, and aerospace components), have stringent requirements for their performance when subjected to collisions and impacts. In order to scientifically and accurately simulate the accidental impact situations that products may encounter in actual use, impact test fixtures have emerged.

[0003] The impact test fixture includes components such as an impact head, a guide device, and a power system. The impact head comes in various materials and shapes, and its quality affects the impact force. The guide device ensures a consistent impact path. The power system can be pneumatic, hydraulic, or electric driven. During operation, the test plate is first fixed, and then the impact head is propelled along the guide device by the speed regulation and control system and the power system. Sensors collect data, which is then analyzed by the data acquisition and processing system to provide a basis for product design optimization.

[0004] In existing technologies, some impact tests are used in actual use. Electronic products may be damaged due to accidental drops or collisions. Without impact tests to simulate these situations, it is difficult to determine whether the casing can remain intact under impact. The results of impact tests can be used to optimize the internal structure and shape of the test board (casing). Without testing, it is difficult to find the weak points of the casing under different impact speeds and angles. Without impact tests, it is difficult to assess whether the impact resistance of the product casing meets quality standards, which will lead to a high failure rate of the product in the market. Therefore, impact test fixtures are proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0031] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 This utility model provides an embodiment of a collision plate testing fixture, including a connecting box 1. The connecting box 1 serves as the basic connecting component of the entire fixture, providing stable support for other components and ensuring a stable platform foundation for the collaborative work of each component, thus guaranteeing the reliability of the overall structure of the testing fixture. A support plate 2 is fixedly connected to the rear of the connecting box 1. The main function of the support plate 2 is to provide a stable mounting support surface for the cylinder 3. The cylinder 3 is fixedly connected to the top of the support plate 2. The cylinder 3 is the key component that generates impact force. Its piston is driven by compressed air or other power sources, thereby driving the connecting shaft 4. The driving end of the cylinder 3 is rotatably connected to the connecting shaft 4, which plays a connecting role in the transmission link of the fixture. The bottom is rotatably connected to the top of the connecting box 1, allowing for flexible rotation. A connecting rod 5 is rotatably connected to the top of the connecting shaft 4. The connecting rod 5 serves as a transmission connector between the connecting shaft 4 and the rotating rod 6, further transmitting the power from the connecting shaft 4 to the rotating rod 6.

[0033] A rotating rod 6 is rotatably connected to the top of the connecting rod 5, and a fixed plate 7 is fixedly connected to the top of the rotating rod 6. Under the power transmitted by the connecting rod 5, the rotating rod 6 rotates around the support column 9, providing stable guidance and support for the movement of the fixed plate 7. The fixed plate 7 is the component that directly contacts the test plate 18 and applies impact force. By precisely controlling its movement, different types of impact conditions can be simulated to perform performance tests on the test plate 18. Two support columns 9 are fixedly connected to the top of each connecting box 1. The support columns 9 provide stable support and guidance for the movement of the rotating rod 6 and the fixed plate 7, and can apply impact force to the test plate 18 from different positions and angles, enriching the test scenarios. Connecting blocks 10 are fixedly connected to the tops of the two support columns 9, and a fixing component for maintaining stability is fixedly connected to the top of the connecting box 1.

[0034] Reference Figure 3 , Figure 4The fixing component includes a motor 11, which serves as the power source for the fixing component and drives the arc gear 12 to rotate. By controlling the forward and reverse rotation and speed of the motor 11, the clamping block 17 can clamp and release the test plate 18, meeting the fixing and replacement operations of the test plate 18 under different testing requirements. The drive end of the motor 11 is fixedly connected to the arc gear 12. The arc gear 12 rotates under the drive of the motor 11, and its unique arc structure meshes with the two semi-circular gears 14, thereby driving the connecting rod 15 and the clamping block 17 to achieve symmetrical clamping or releasing actions on both sides of the test plate 18, ensuring the stability and reliability of the test plate 18 fixing. The top of the connecting box 1 is fixedly connected to two support frames 13, which provide a frame structure for the installation and rotation support of components such as the semi-circular gear 14 and the arc gear 12. The support frame 13 is internally connected to a semi-circular gear 14, which meshes with the arc gear 12 for transmission. The connecting rod 15 fixedly connected to its front side moves up and down as the semi-circular gear 14 rotates. The outer side of the arc gear 12 meshes with the outer side of the two semi-circular gears 14. The tooth profile of the semi-circular gear 14 and the matching accuracy of the arc gear 12 directly affect the working reliability of the fixing component and the movement accuracy of the clamp 17.

[0035] Connecting rod 15 is fixedly connected to the front side of the semi-circular gear 14. Connecting rod 15 serves as the connecting component between the semi-circular gear 14 and the clamping block 17, converting the rotation of the semi-circular gear 14 into the vertical movement of the clamping block 17. The clamping block 17 is fixedly connected to the top of connecting rod 15, and the clamping block 17 directly contacts the test plate 18 and applies clamping force. The precise movement of the clamping block 17 driven by connecting rod 15 is a key factor in ensuring the reliable fixation of the test plate 18. Connecting rod 2 16 is rotatably connected to the bottom front side of one connecting rod 15. Connecting rod 2 16 connects the bottom front side of one connecting rod 15 to the rear side of the other connecting rod 15, thus linking the two connecting rods 15.

[0036] Reference Figures 2 to 4The far side of the fixed plate 7 is rotatably connected to the near side of the two support columns 9. The bottom of the connecting shaft 4 is rotatably connected to the top of the connecting box 1. An arc-shaped support block 20 is fixedly connected to the top of the connecting box 1, and its top is in contact with the top of the test plate 18. Its main function is to provide support for the test plate 18 when it is not impacted, helping to maintain the levelness and stability of the test plate 18. During impact, it works in conjunction with other impact components to make the force on the test plate 18 more uniform, simulating a more realistic impact environment and improving the accuracy of the test results. The top of the arc-shaped support block 20 is in contact with the top of the test plate 18, and an impact block 8 is fixedly connected to the bottom of the support column 9, with the impact block 8 located at the bottom of the support column 9 and in contact with the top of the test plate 18. When the fixed plate 7 impacts the test plate 18, the impact block 8 applies an additional impact force to the test plate 18 from below, creating a pincer impact effect with the fixed plate 7. This allows for a more comprehensive testing of the impact resistance of the test plate 18, and the evaluation of its structural strength and stability under impact forces from different directions. The bottom of the impact block 8 contacts the top of the test plate 18, and the exterior of the two arc-shaped gears 12 are rotatably connected to the interior of the two support frames 13, ensuring the accurate movement trajectory of each component during the operation of the fixed assembly and maintaining the stability and integrity of the entire fixed assembly structure.

[0037] Both connecting rods 15 are externally slidably connected to the inside of the support frame 13. A clamping block 17 is fixed to the top of each connecting rod 15. Driven by the semi-circular gear 14, the clamping block 17 applies or releases clamping force on the test plate 18. Its external slidable connection to the inside of the support frame 13 ensures the stability and directionality of the movement, preventing the clamping block 17 from shifting during movement. The rear side of the other connecting rod 15 is rotatably connected to the front side of the connecting rod 16, ensuring that the test plate 18 is subjected to uniform force during clamping and improving the fixing effect. The adjacent sides of the two clamping blocks 17 contact the distant sides of the test plate 18. Handles 19 are fixedly connected to both sides of the left side of the connecting box 1, facilitating the operator's handling and movement of the entire impact plate testing fixture. Its design conforms to ergonomic principles, making it easy to grip and apply force. During operations such as moving, installing, or adjusting the position of the fixture, it provides the operator with a convenient point of leverage, improving operational efficiency and convenience, while also ensuring the safety of the fixture during handling. The two handles 19 are fixedly connected to the opposite sides of the locks 21, which can prevent the components of the tooling from becoming loose or shifting due to accidental collisions or shaking, protect the integrity of the internal structure of the tooling, and facilitate centralized storage and management of the tooling, thereby improving the storage safety and stability of the tooling.

[0038] The working principle is as follows: First, under the power of compressed air or other power sources, the piston movement of cylinder 3 drives the connecting shaft 4 to rotate. The rotation of the connecting shaft 4 is transmitted to the connecting rod 5, causing the connecting rod 5 to swing and drive the rotating rod 6 to rotate around the support column 9. The rotating rod 6 then drives the fixed plate 7 to move vertically, realizing the impact on the test plate 18. During this process, the support column 9 provides stable support and guidance for the rotating rod 6 and the fixed plate 7, ensuring accurate impact direction and stable force, thereby accurately simulating different impact conditions and testing the performance of the test plate 18. It can directly test its structural integrity when subjected to impact force. Different materials react differently when impacted. For example, metal materials will dent, while plastic materials will crack. By using the impact plate test to simulate collisions at different speeds, the internal structure and shape of the bumper can be optimized based on the test results to improve its energy absorption and buffering performance.

[0039] When motor 11 starts rotating forward, it drives the arc gear 12 to rotate. The arc gear 12 meshes with two semi-circular gears 14, causing the semi-circular gears 14 to rotate synchronously in the opposite direction. The connecting rod 15 on the front side of the semi-circular gear 14 moves left and right accordingly. One of the connecting rods 15 is linked to the other connecting rod 15 through connecting rod 16, allowing the two clamping blocks 17 to approach the test plate 18 simultaneously. When motor 11 reverses, all components move in the opposite direction, and the clamping blocks 17 release the test plate 18. In this way, by controlling the rotation direction of the arc gear 12 through motor 11, the clamping blocks 17 can move towards the test plate 18. The clamping and releasing operation meets different testing needs. The clamping device has a certain adjustment function to adapt to test plates 18 of different sizes. When testing industrial equipment test plates 18 with hard materials and heavy weight, if the test plate 18 is thrown, it may damage other precision instruments or injure nearby personnel. The firm clamping can limit the test plate 18 within a certain range to avoid such dangerous situations, ensure that the impact direction is consistent with the actual working conditions, and enable the test results to truly reflect the impact resistance performance of the test plate 18 in the actual use scenario.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
