Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology for ceramic fiber paper, specifically a tensile testing machine for ceramic fiber paper. Background Technology

[0002] Ceramic fiber paper is a lightweight, flexible, high-performance material made of ceramic fibers. It has properties such as high temperature resistance, heat insulation, electrical insulation, and chemical stability, and is widely used in industries such as industry, electronics, and aerospace. After ceramic fiber paper is produced, it needs to be tested for tensile strength using a tensile testing machine to test its performance. However, most of the existing tensile testing machines have their testing devices exposed to the outside. When the paper breaks during the testing process, the broken material or debris can easily injure workers and be inhaled by them, endangering their health. To address this, a tensile testing machine for ceramic fiber paper was proposed. Utility Model Content

[0019] Furthermore, this embodiment ensures a sealed state during testing through the protective cover 2 and the switch door 5, preventing broken materials or debris from injuring testing personnel.

Example

[0020] Based on Embodiment 1, a preferred embodiment of the tensile testing machine for ceramic fiber paper provided by this utility model is as follows: Figure 1-4 As shown: The first clamping frame 48 and the second clamping frame 49 are both rotatably connected to a rotating rod 411 at one end near the center of the protective cover 2. A rotating plate 412 is fixedly connected to one side of the outer wall of the rotating rod 411. Multiple protrusions 413 are fixedly connected to the outer wall of the rotating rod 411. Electric telescopic rods 414 are fixedly connected to both sides of the inner wall of the first clamping frame 48 and the second clamping frame 49 at the end away from the center of the protective cover 2. The output end of the electric telescopic rods 414 is fixedly connected to a fixing plate 415. Limiting rods 416 are fixedly connected to the middle of both sides of the inner bottom surface of the protective cover 2. Connecting rods 417 are fixedly connected to the middle of the outer walls of both sides of the first clamping frame 48 and the second clamping frame 49 at the end away from the center of the protective cover 2. The side of the connecting rod 417 away from the center of the protective cover 2 slides on the limiting rods 416. The front end of the protective cover 2 is hinged to a switch door 5. A transparent observation window 6 is provided in the middle of the switch door 5. A handle 7 is fixedly connected to one side of the front outer wall of the switch door 5. A control panel 8 is fixedly connected to the side of the front outer wall of the switch door 5 away from the handle 7.

[0021] Furthermore, by placing the threaded rod 45 outside the protective cover 2 in this embodiment, it is possible to prevent materials and debris that break off during the testing process from getting tangled on the threaded rod 45 and affecting its normal rotation, thus achieving high practical performance.

[0022] In use, the two ends of the ceramic fiber paper to be tested are placed on the first clamping frame 48 and the second clamping frame 49 respectively, and the two ends are wrapped around the rotating rod 411 respectively. The fixing plate 415 is driven by the electric telescopic rod 414 to fix the ceramic fiber paper. The protrusion 413 increases its friction and ensures its clamping stability. After clamping and unblocking, the servo motor 44 drives the threaded rod 45 to rotate, and the rotation of the threaded rod 45 drives the threaded sleeve 46 to move, thereby driving the first clamping frame 48 to descend through the connecting block 47.

Then, the dust is sucked into the dust collection box 31 through the suction pipe 34, the suction hood 33 and the connecting pipe 35 by the dust pump 32, avoiding the testing personnel from inhaling it into their bodies, thus ensuring high safety.

[0023] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
