Description

Technical Field

[0001] This utility model relates to the field of materials testing technology, and in particular to a fatigue testing device for fluorescent materials. Background Technology

[0002] Fluorescent materials can emit longer wavelengths of light after absorbing light of a specific wavelength; this is known as fluorescence. The luminescence process occurs when electrons transition from an excited state back to the ground state, releasing energy and emitting light. Fluorescent materials possess excellent flexibility and deformability, leading to a wide range of applications, including display technology and biomedicine. Therefore, to ensure the quality of fluorescent materials, fatigue testing machines are needed to perform fatigue tests. For example, a pneumatic clamp for a high-temperature fatigue testing machine for metallic materials (authorization announcement number CN 218157236 U, authorization announcement date 2022.12.27) is suitable for metallic materials but not for fluorescent materials. Utility Model Content

[0003] The purpose of this invention is to provide a fluorescent material fatigue resistance testing device specifically for the detection of fluorescent materials.

[0004] To achieve the above-mentioned objectives, the fluorescent material fatigue testing device of this utility model adopts the following technical solution:

[0005] A fatigue testing device for fluorescent materials includes a base and a test platform mounted on the base. The test platform has a fixed frame and a movable frame, with a tensile gap between the fixed frame and the movable frame. Both the fixed frame and the movable frame are equipped with clamping components for clamping the fluorescent material. One end of the fluorescent material is clamped on the fixed frame, and the other end of the fluorescent material is clamped on the movable frame. The movable frame is equipped with a displacement component that drives its horizontal displacement, thereby stretching the fluorescent material through displacement. The clamping component includes an upper clamp and a lower clamp, with the fluorescent material clamped between the upper clamp and the lower clamp. The lower clamp is mounted on the movable frame or the fixed frame, and the upper clamp is located above the lower clamp. The upper clamp is equipped with a lifting mechanism that drives its vertical lifting.

[0006] Preferably, the lifting mechanism is a clamping cylinder.

[0007] Preferably, the lower clamping seat is provided with a guide post, the upper clamping seat is provided with a guide hole adapted to the guide post, the top of the guide post is provided with a mounting seat, the cylinder of the clamping cylinder is mounted on the mounting seat, and the piston rod of the clamping cylinder passes through the mounting seat and connects to the upper clamping seat. The guide post serves to guide the vertical movement of the upper clamping seat.

[0008] Preferably, the bottom surface of the upper clamp for contacting the fluorescent material is configured as an upper corrugated surface, and the top surface of the lower clamp for contacting the fluorescent material is configured as a lower corrugated surface; the upper and lower corrugated surfaces cooperate, with the crests of the upper corrugated surface corresponding to the troughs of the lower corrugated surface. Since the fluorescent material is clamped between the upper and lower corrugated surfaces, the frictional force between the fluorescent material and the upper and lower clamps is increased, ensuring stable clamping of the fluorescent material between the upper and lower clamps.

[0009] Preferably, a spring is provided between the upper clamp and the lower clamp. The spring provides a buffering effect, allowing the upper clamp to slowly press against the fluorescent material, thus pressing the fluorescent material firmly against the lower clamp.

[0010] Preferably, a tension spring is provided between the fixed frame and the movable frame. The tension spring provides a cushioning effect, allowing the fluorescent material to be stretched slowly.

[0011] Preferably, the displacement component is a helical transmission mechanism.

[0012] Preferably, the screw transmission mechanism includes a motor, a lead screw, and a lead screw nut; the movable frame is provided with a slide block; the test platform is provided with a slide rail; the slide block and the slide rail cooperate to slide; the motor is mounted on the test platform; the output shaft of the motor is connected to the lead screw; the slide block is provided with a lead screw nut; the lead screw and the lead screw nut are threadedly connected.

[0013] Preferably, the fluorescent material is horizontally clamped between the fixed frame and the movable frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] The fluorescent material of this invention is clamped between a fixed frame and a movable frame by a clamping assembly. The clamping assembly is driven by a lifting mechanism to move the upper clamping seat, pressing the fluorescent material tightly against the lower clamping seat. The clamping and fixing effect is good, especially suitable for fixing flexible fluorescent materials. When conducting fatigue tests, only the movable frame needs to be driven to make horizontal displacement to achieve the stretching of the fluorescent material. The overall structure is simple, the design is reasonable, and it is practical. Attached Figure Description

[0023] like Figure 1-5As shown, a fatigue testing device for fluorescent materials includes a base 1 and a test platform 5 disposed on the base 1. The test platform 5 is provided with a fixed frame 2 and a movable frame 6, and a tensile gap is formed between the fixed frame 2 and the movable frame 6. Both the fixed frame 2 and the movable frame 6 are provided with clamping components 3 for clamping fluorescent materials 7. One end of the fluorescent material 7 is clamped on the fixed frame 2, and the other end of the fluorescent material 7 is clamped on the movable frame 6. The fluorescent material 7 is clamped horizontally between the fixed frame 2 and the movable frame 6. A tension spring 9 is provided between the fixed frame 2 and the movable frame 6. The movable frame 6 is equipped with a displacement component 4 to drive its horizontal displacement. The movable frame 6 stretches the fluorescent material 7 through displacement. The displacement component 4 is a screw drive mechanism, which includes a motor 403, a lead screw 404, and a lead screw nut 405. The movable frame 6 is equipped with a slide block 401, and the test platform 5 is equipped with a slide rail 402. The slide block 401 and the slide rail 402 cooperate to slide. The motor 403 is mounted on the test platform 5. The output shaft of the motor 403 is connected to the lead screw 404. The slide block is equipped with a lead screw nut 405. The lead screw 404 and the lead screw nut 405... 5. Threaded connection; Clamping assembly 3 includes an upper clamp 304 and a lower clamp 305. Fluorescent material 7 is clamped between the upper clamp 304 and the lower clamp 305. A spring 8 is provided between the upper clamp 304 and the lower clamp 305. The bottom surface of the upper clamp 304 that contacts the fluorescent material 7 is set as an upper corrugated surface 304a, and the top surface of the lower clamp 305 that contacts the fluorescent material 7 is set as a lower corrugated surface 305a. The upper corrugated surface 304a and the lower corrugated surface 305a cooperate, with the crest of the upper corrugated surface 304a corresponding to the trough of the lower corrugated surface 305a. The lower clamp 305 is mounted on the movable frame 6 or the fixed frame 2, and the upper clamp 304 is located above the lower clamp 305. The upper clamp 304 is provided with a lifting mechanism to drive it to move vertically. The lifting mechanism is a clamping cylinder 301. The lower clamp 305 is provided with a guide post 303, and the upper clamp 304 is provided with a guide hole adapted to the guide post 303. The top of the guide post 303 is provided with a mounting seat 302. The cylinder of the clamping cylinder 301 is mounted on the mounting seat 302, and the piston rod of the clamping cylinder 301 passes through the mounting seat 302 and connects to the upper clamp 304.

[0024] The specific working process and principle of this utility model are as follows: One end of the fluorescent material 7 is placed on the lower clamp 305 of the fixed frame 2, and the other end of the fluorescent material 7 is placed on the lower clamp 305 of the movable frame 6. Then, the clamping cylinder 301 is activated, driving the upper clamp 304 to press down on the fluorescent material 7, pressing the fluorescent material 7 tightly against the lower clamp 305. Under the action of the upper corrugated surface 304a and the lower corrugated surface 305a, the frictional force between the fluorescent material 7 and the upper clamp 304 and the lower clamp 305 is increased, further ensuring... The fluorescent material 7 is stably clamped between the upper clamp 304 and the lower clamp 305. Then, the motor 403 drives the lead screw 404 to rotate, and the rotation of the lead screw 404 drives the lead screw nut 405 to move, thereby realizing the displacement of the moving frame 6. Since one end of the fluorescent material 7 is fixed on the moving frame 6, the displacement of the moving frame 6 realizes the stretching of the fluorescent material 7. Then, the luminescence of the fluorescent material is observed until the fluorescent material stops luminescence. The number of bending times is calculated, thereby completing the fatigue test of the fluorescent material 7.
