Abstract
The invention relates to a fatigue tester, which relates to an instrument for testing, wherein two torsion shafts are vertically arranged in a cabinet through a bearing, the upper ends of the torsion shafts are inserted in a high-temperature cabinet, the upper ends of the torsion shafts are connected with a lower chuck, and the lower ends of the torsion shafts are concentrically connected with a relative wobble wheel, a speed reduction motor is further arranged in the cabinet, the output end of the speed reduction motor is connected with an eccentric wheel, a torque rod is hinged between the eccentric wheel and either of the wobble wheels, a connecting bar is hinged between the two wobble wheels, and an upper chuck is vertically arranged in the high-temperature cabinet. Samples are clamped between the upper chuck and the lower chuck, two groups of samples are led to simultaneously do torsion fatigue tests with different frequencies under different temperature conditions through controlling temperatures in the high-temperature cabinet to improve the work efficiency of tests, and the fatigue tester is further beneficial for comparing test data.
Description
Technical field
The present invention relates to a kind of test instrument, especially for detecting the distortion fatigue behaviour index of solid adhesive tape under all temps condition.
Background technology
Solid adhesive tape product in the past detects the requirement of not twisting fatigue behaviour in the index, and solid adhesive tape in use needs to stand high-frequency distortion, the requirement that product can not adapt to its working environment often occurs, and the life-span has a greatly reduced quality.
Summary of the invention
The object of the invention is to design the repeated torsion test machine of the solid adhesive tape distortion of a kind of logical detection fatigue behaviour index.
The present invention includes cabinet, high-temperature cabinet, in cabinet, vertically arrange two torsion shafts by bearing, the upper end of each torsion shaft is inserted in the high-temperature cabinet, upper end at each torsion shaft connects lower chuck, the lower end of each torsion shaft connects with one heart corresponding wobble wheel, also arranges a reducing motor in cabinet, connects an eccentric wheel at the output terminal of reducing motor, at eccentric wheel with wherein be hinged a torque rod between a wobble wheel, be hinged a connecting link between two wobble wheels; The vertical upper grip of arranging in high-temperature cabinet.
During test, specimen holder is held between upper and lower two chucks, starts reducing motor, because eccentric effect makes torque rod drive deflecting wheel around its back and forth rotation of center of circle do, so, back and forth reverse with the relative upper grip of lower chuck of torsion shaft upper end.Can to improve the work efficiency of test, also be beneficial to the contrast of test figure by the temperature in the control high-temperature cabinet to simultaneously two groups of samples are done the repeated torsion test of different frequency under condition of different temperatures.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 be among Fig. 1 A-A to view.
Embodiment
As shown in Figure 1, 2, the present invention includes cabinet 1, high-temperature cabinet 7, in cabinet 1 by two cover bearings respectively vertical arrange torsion shaft 5 and 5 ', torsion shaft 5 and 5 ' the upper end be inserted into respectively in the high-temperature cabinet 7, torsion shaft 5 and 5 ' the upper end be connected respectively lower chuck 6 and 6 '.Torsion shaft 5 and 5 ' the lower end be connected respectively with one heart wobble wheel 4 and 4 '.
In cabinet 1, also arrange a reducing motor 2, connect an eccentric wheel 3, between eccentric wheel 3 and wobble wheel 4, be hinged a torque rod 12 by pin respectively at the output terminal of reducing motor 2, wobble wheel 4 ' and wobble wheel 4 between also be hinged a connecting link 14.
In high-temperature cabinet 7 respectively by stationary shaft 9,9 ' vertically arrange upper grip 10 and 10 '.
Among the figure, 8 is sample, and 11 is electric cabinet.
