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
The present invention relates to a kind of test apparatus that is used for testing elastic fabric sample fatigue behaviour.
Background technology
For the test of elastic fabric sample fatigue behaviour, also there is not at present a kind of special self-reacting device, the judgement of the fatigue performance of elastic fabric is mainly relied on impression or only carries out simple manual test.Existing way has too many experience composition and standard inconsistency, and therefore present means of testing can not adapt to the demand of textile industry high speed development.
Summary of the invention
Technical matters to be solved by this invention is, a kind of fatigue tester is provided, and it has simple and practical structure and stabilized quality performance, can satisfy the standardized test requirement of elastic fabric sample fatigue well, to overcome the deficiency of above-mentioned present situation.
The present invention has adopted following technical scheme.
A kind of fatigue tester comprises the frame that is installed on the support, it is characterized in that: the guide rail lower end is fixed on the support, fixedlys connected with frame in the upper end; Last clamper is fixedlyed connected with frame, and lower gripper is slidingly mounted on the guide rail; The wheel shaft connecting crank of the power wheel that is connected with main drive of motor, the other end of the connecting rod that cooperates with crank is connected with lower gripper.
Cylinder all is installed on last clamper, the lower gripper.
Described upward clamper is three groups; Described guide rail is parallel two.
Also comprise the slide plate that is slidingly connected with guide rail, main motor and power wheel are installed on this slide plate.
The motor that spaces also is installed on support, and the latter's output shaft directly or by reducing gear is connected with the leading screw lower end, and leading screw is connected with the slide plate spiral.
Last clamper is connected on the frame by sensor.
Sensor is connected with control device; Control device is connected with display device.
Good effect of the present invention is: the present invention can make the test procedure standardization of elastic fabric sample fatigue.Sample stands the stretching circulation of certain number of times and the retraction of certain hour, therefore, can test suitable performance and compares with the respective performances of fatigue testing specimen not.For some performance, for example: elongation, modulus, on the sample of fatigue, make suitable measurement markers, these marks also are used for test subsequently.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, this fatigue tester comprises the frame 6 that is installed on the support 1.Article two, parallel guide rail 7 lower ends all are fixed on the support 1, all fixedly connected with frame 6 in the upper end.Last clamper 9 can be directly fixing with frame 6, also can fixedly connected with frame 6 by sensor 8, and lower gripper 11 is slidingly mounted on the guide rail 7.On last clamper 9 and the lower gripper 11 cylinder 10 is installed also, its effect is to provide power for clamping sample.
When main motor 3 is worked, wheel shaft by power wheel 5 drives toggle work, and then drive lower gripper 11 and pump along the rate of circulation of guide rail 7 with per minute 60,50,40,30 ± 1 times, one to three sample that is held between the upper and lower holder is stretched simultaneously repeatedly, implement the Nai Bilao performance test of sample.Back and forth the shift motion of clamper can be adjusted between 50mm and the 250mm.
By the tie point position of adjustment crank 13 with connecting rod 12, the radius of clean-up that can regulate crank 13, and then realization is to the adjusting of lower gripper 11 shift motions.
The motor 14 that spaces also is installed on support 1, and the latter's output shaft directly or by reducing gear is connected with leading screw 4 lower ends.Leading screw 4 is connected with slide plate 2 spirals, and the upper end of leading screw 4 is fixed on the frame 6.When spacing motor 14 work, drive leading screw 4 rotations (just change or reverse), driving slide plate 2 moves up and down along guide rail 7 and spaces with adjustment, and described spacing is meant distance between clamper 9 lower jaws and lower gripper 11 upper jaws.
