Description

Technical Field

[0001] This utility model relates to the technical field of aerospace composite material testing equipment, specifically a device for testing the strength of aerospace materials. Background Technology

[0002] Aerospace composite materials are typically composed of materials such as carbon fiber, glass fiber, ceramic fiber, and resin, and are widely used in the manufacture of aircraft structural components, airborne equipment, and other aerospace devices. In the aerospace field, the strength and durability of materials are crucial for ensuring aircraft safety; therefore, strength testing of relevant materials is necessary.

[0003] Traditional testing methods typically employ compression and bending, but these methods result in a fixed stress location when testing composite materials, making it difficult to adjust the stress points as needed and lacking flexibility. Furthermore, material fragments easily scatter onto the testing platform during the test, making cleaning tedious and further reducing testing efficiency. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] In view of the above situation and to overcome the current technical defects, this utility model provides an easy-to-use aerospace material strength testing device. This device allows for convenient and flexible adjustment of the material testing position and easy cleaning and collection of generated fragments, thus improving the flexibility and convenience of testing.

The testing table is rotatably mounted on the testing frame. The adjustment component is installed inside the upper part of the testing frame. The pressure testing machine is installed on the adjustment component and corresponds to the testing table. The adjustment component includes a forward and reverse motor, a lead screw, and a mounting base. The lead screw is rotatably mounted inside the upper part of the testing frame. The forward and reverse motor is installed on one side of the testing frame. The output shaft of the forward and reverse motor is connected to one end of the lead screw. The mounting base is slidably mounted on the upper part of the testing frame and is threadedly connected to the lead screw. The pressure testing machine is installed on the mounting base.

[0006] Preferred technical solution 1: A guide rod is installed inside the testing frame, and the guide rod is used to guide and limit the mounting seat.

[0007] Preferred technical solution 2: The testing platform is provided with symmetrical support frames on both sides of the upper end. The support frames are threadedly connected with threaded fastening rods. One end of the threaded fastening rod is rotatably provided with a material fixing frame.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0021] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0022] Example 1

[0023] As per the instruction manual Figure 1-4 As shown, the technical solution adopted by this utility model is as follows: The aerospace material strength testing device provided by this solution includes a testing frame 1, a testing platform 2, a pressure testing machine 3, and an adjustment assembly 4. The testing platform 2 is rotatably mounted on the testing frame 1. The adjustment assembly 4 is installed inside the upper part of the testing frame 1. The pressure testing machine 3 is installed on the adjustment assembly 4 and corresponds to the testing platform 2. The adjustment assembly 4 includes a forward and reverse motor 5, a lead screw 6, and a mounting base 7. The lead screw 6 is rotatably mounted inside the upper part of the testing frame 1. The forward and reverse motor 5 is installed on one side of the testing frame 1, and the output shaft of the forward and reverse motor 5 is connected to one end of the lead screw 6. Mounting base 7 is slidably disposed on the upper end of testing frame 1. Mounting base 7 is threadedly connected to lead screw 6. Pressure testing machine 3 is mounted on mounting base 7. Guide rod 8 is installed inside testing frame 1. Guide rod 8 is used to guide and limit mounting base 7. Support frame 9 is symmetrically provided on both sides of the upper end of testing table 2. Threaded fastening rod 10 is threadedly connected to support frame 9. Material fixing frame 11 is rotatably provided at one end of threaded fastening rod 10. Material fixing frame 11 is set in an L-shaped structure. Guide support rod 12 is slidably provided on support frame 9. One end of guide support rod 12 is connected to the rear end of material fixing frame 11 and is used to guide and support material fixing frame 11.

[0024] Tightening the threaded fastening rod 10 drives the material fixing frame 11 to clamp and fix both ends of the composite material to be tested. The pressure testing machine 3 is started to press down on the composite material through the pressure testing probe to perform pressure testing. During the test, the forward and reverse motor 5 is started to drive the lead screw 6 to rotate. The lead screw 6 drives the mounting base 7 to move the pressure testing machine 3 laterally to adjust the test position. Since the mounting base 7 is slidably connected to the test frame 1 and is guided and limited by the guide rod 8, it can stably drive the pressure testing machine 3 to move steadily, ensuring the accuracy of the test pressure point. The pressure testing machine 3 can be a commonly used testing machine with a digital pressure sensor on the market to detect the pressure changes on the composite material in real time and ensure the accuracy of the test results.

[0025] Example 2

[0026] Based on Example 1, in order to improve the flexibility of testing materials and facilitate the cleaning and collection of material fragments, as per the appendix to the instruction manual... Figure 1-4 As shown, threaded fixing pins 13 are symmetrically threaded on both sides of the testing frame 1. Multiple sets of pin holes 14 are arranged around the outer wall of the testing platform 2. The threaded fixing pins 13 are engaged with one set of pin holes 14. A ring bearing seat 15 is connected between the testing platform 2 and the testing frame 1. The ring bearing seat 15 is made of high-strength alloy steel and is used to improve the pressure resistance of the testing platform 2. A trough 16 for material discharge is provided in the middle of the testing platform 2. A collection box 17 for material collection is provided at the bottom of the testing frame 1.

[0027] During material testing, rotating the testing platform 2 causes the clamped material to deflect at an angle, which, in conjunction with the adjustment component 4, allows the pressure testing machine 3 to further adjust the testing position of the material flexibly. After adjustment, screwing the threaded fixing pin 13 into the corresponding pin hole fixes and limits the testing platform 2, improving stability. When the material is subjected to pressure strength testing, the broken material falls into the collection box 17 through the trough 16, thus facilitating the collection of material fragments.
