Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental equipment technology, specifically a high-altitude simulation test device. Background Technology
[0002] High-altitude simulation test equipment is a common experimental device in the current testing field. It is usually used to simulate the low air pressure, large temperature difference, ultraviolet radiation and other working conditions at high altitudes, and is used to test cables, batteries or the entire equipment.
[0003] Current equipment of this type typically consists of large enclosures. For testing small parts, specific fixtures are usually used to secure them within the enclosure. This is because such scenarios often include other tests, such as aging tests and dust tests, making large, fully-equipped test chambers more advantageous. However, for testing some materials, it may only be necessary to test under pressure and ultraviolet light conditions. Using existing large test chambers would be costly in such cases. Therefore, smaller test chambers could be developed specifically for this purpose. Utility Model Content

[0006] This utility model discloses a high-altitude simulation test device, which includes a test chamber body and a vertical rail fixedly installed inside the test chamber body.
[0007] The test chamber is equipped with a vacuum system and an ultraviolet lamp. The ultraviolet lamp is installed on the top or inner wall of the test chamber.
[0008] An adjustable bracket is installed on the vertical rail, and a support frame is fixedly installed on one side of the adjustable bracket;
[0009] The front end of the support frame is equipped with a rotating fixture, which is used to fix and clamp the test piece to be tested. The rotating fixture is installed horizontally or vertically to drive the test piece to be tested to rotate horizontally or vertically.
[0010] As a preferred technical solution of this utility model, at least two sets of adjustable brackets are installed on the vertical rail. The adjustable brackets are frame-shaped structures. Bolts are installed on the side walls of the adjustable brackets. When the bolts are loosened, the adjustable brackets can slide along the vertical rail to adjust the installation height. When the bolts are tightened, they are used to fix and position the adjustable brackets.
[0011] As a preferred technical solution of this utility model, the support frame on a single adjustable bracket has two horizontally spaced supports.
[0012] As a preferred technical solution of this utility model, the rotary tooling includes a tooling base, the rear end of which is mounted on the rotating shaft of the drive motor, and the base of the drive motor is fixedly mounted on the support frame.
[0013] As a preferred technical solution of this utility model, the fixture base is U-shaped in shape. The lower part of the fixture base is provided with a forward-extending fixed gripper, and the upper part of the fixture base is embedded with a movable motor. The output shaft of the movable motor is connected to the movable gripper. Under the drive of the movable motor, the movable gripper swings toward or away from the fixed gripper to achieve the fixation and release of the test piece to be tested.
[0014] The beneficial effects of this utility model are:
[0015] This invention designs a small test chamber to test material samples under high altitude, low pressure, and ultraviolet radiation conditions. By setting a rotating fixture, it can ensure the uniformity of ultraviolet radiation exposure and improve the test feedback effect. Attached Figure Description
[0016] The accompanying drawings are provided to further illustrate the present invention and form part of the specification. They are used together with the embodiments of the present invention to explain the present invention, but do not constitute a limitation thereof. In the drawings:
[0017] Figure 1 This is a schematic diagram of the overall structure of this utility model.
[0018] Figure 2 This is a schematic diagram of the result of the rotating tooling of this utility model. Detailed Implementation
[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.
[0020] Example: Figure 1-2 As shown, it includes the test chamber body 1 and the vertical rail 2 fixedly installed inside the test chamber body 1;
[0021] The test chamber body 1 is equipped with a vacuum system and an ultraviolet lamp. The ultraviolet lamp is installed on the top of the inner cavity or the inner wall of the test chamber body 1.
[0022] An adjustable bracket 3 is installed on the vertical rail 2, and a support frame 4 is fixedly installed on one side of the adjustable bracket 3. At least two sets of adjustable brackets 3 are installed on the vertical rail 2. The adjustable bracket 3 is a frame structure. Bolts are installed on the side wall of the adjustable bracket 3. When the bolts are loosened, the adjustable bracket 3 can slide along the vertical rail 2 to adjust the installation height. When the bolts are tightened, they are used to fix and position the adjustable bracket 3.
[0023] The front end of the support frame 4 is equipped with a rotating fixture 5, which is used to fix and clamp the test specimen to be tested. Before testing, the test specimen has undergone a sample preparation step, usually by making the material sample into a sheet. This is common for metal materials or engineering plastics. Under ultraviolet light and low pressure conditions, the material itself is tested to see if it deforms, or if there are cracks or discoloration on the material surface.
[0024] Each adjustable bracket 3 has two horizontally spaced support frames 4. Test pieces can also be placed directly on the two support frames 4 for placement testing.
[0025] The rotating fixture 5 is installed horizontally or vertically to drive the test piece to rotate horizontally or vertically. (Refer to...) Figure 2 As shown, the rotating fixture 5 includes a fixture base 51. The rear end of the fixture base 51 is mounted on the rotating shaft of the drive motor 54, and the base of the drive motor 54 is fixedly mounted on the support frame 4. The fixture base 51 has an overall U-shaped structure. The lower part of the fixture base 51 is provided with a forward-extending fixed gripper 52, and the upper part of the fixture base 51 is embedded with a movable motor 55. The output shaft of the movable motor 55 is driven and connected to a movable gripper 56. Under the drive of the movable motor 55, the movable gripper 56 swings toward or away from the fixed gripper 52 to achieve the fixation and release of the test piece to be tested.
[0026] The rotating fixture, besides allowing for switching of material states to ensure each surface is exposed to UV radiation, can also be used for other applications such as air blowing tests and stress tests. Overall, it reduces equipment costs and, through its design, broadens the range of applications for simple material testing.
[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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.
