Embodiment Construction

[0014] like figure 1 As shown, the fatigue testing machine includes a frame 6 installed on the machine base 1 . The lower ends of the two parallel guide rails 7 are all fixed on the base 1, and the upper ends are fixedly connected with the frame 6. The upper holder 9 can be directly fixed with the frame 6 , and can also be fixedly connected with the frame 6 through the sensor 8 , and the lower holder 11 is slidably installed on the guide rail 7 . An air cylinder 10 is also installed on the upper holder 9 and the lower holder 11, and its function is to provide power for clamping the sample.

[0015] The skateboard 2 is also slidingly connected with the guide rail 7, and the main motor 3 and the transmission wheel 5 are fixedly installed on the skateboard 2. The axle of the transmission wheel 5 is connected to the crank 13, and the upper end of the connecting rod 12 matched with the crank 13 is connected to the lower holder 11. .

[0016] When the main motor 3 is working, the...

Abstract

The invention provides a fatigue tester. The lower end of the guide rail (7) is fixed on the engine base (1) and the upper end is permanently connected with the frame (6). The top clamp (9) is permanently connected with the frame (6) and the lower clamp (11) is slidably mounted on the guide rail (7). The axle of a driver (5) is in drive joint with the main electric machine (3) and another end of the connecting lever (12) cooperated with the crank is connected with the lower clamp (11). The testing program of fatigue of the elastic fabric sample is standardized. The sample is subjected to cycle of stretching and retracting for a number of times, thus the proper performance can be tested and compared with the corresponding performance of the not-fatigue sample.

Description

technical field [0001] The invention relates to a test instrument for testing the fatigue performance of elastic fabric samples. Background technique [0002] For the test of the fatigue performance of elastic fabric samples, there is no special automatic instrument at present, and the judgment of the fatigue resistance performance of elastic fabrics mainly depends on the perception or only simple manual tests. The current practice has too many empirical components and inconsistent standards, so the current testing methods can no longer meet the needs of the rapid development of the textile industry. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fatigue testing machine, which has a simple and practical structure and stable quality performance, and can well meet the standardized test requirements for the fatigue of elastic fabric samples, so as to overcome the shortcomings of the above-mentioned status quo. ...
