It holds state and load mode classification is shown in Table 1, be tensile loads, operating condition of test figure can be seen as shown in Fig. 1~Fig. 2 by table 1
Going out, the loading condition of detachable tie-down point is more, and conventional method is the fixture processed suitable for different operating mode angles, but
It is the raising that such result not only causes cost, but also each operating mode is finished and will changed the outfit, and causes inefficiency.
1 loading environment of table
The content of the invention
The purpose of the present invention is：A kind of jig platform for the experiment of detachable tie-down point and its user are provided
Method.It is therein any one that the jig platform can ensure that detachable tie-down point experiment two degree of freedom α and β are adjusted to table 1
Kind composite condition, so as to measure the mechanical property of detachable tie-down point.
The technical scheme is that：A kind of test fixture for detachable tie-down point slow test, including flower
Key axis 2, spline ears seat 3, turntable 4, the spline tooth in chassis 5, wherein splined shaft 2, spline ears seat 3,5 inside spline of chassis
Interval is 15 °, can realize the adjustment of 15 ° of multiple angles；On the turntable 4 sliding-rail groove, the cunning are equipped with along its diameter
The section of track slot is dovetail shaped, and detachable tie-down point can slip into turntable center and is kept fixed along sliding-rail groove one end；Chassis 5
On bolt hole can realize and 0 ° of the sliding-rail groove of turntable, 30 ° of relative angle；Before experiment, by splined shaft ears seat 3 and chassis
5 operating mode angle [alpha] adjustment corner according to demand, and pass through splined shaft 2 and the two connection is fixed up, detachable be tethered at is connect
First 1 insertion turntable 4, the operating mode angle beta of the assembly of detachable tie-down point 1 and turntable 4 and chassis 5 according to demand is adjusted
Corner, and pass through bolt and be connected turntable 4 with chassis 5 and be fixed up, spline ears seat 3 leads to the test platform mounted in testing machine
Bolt is crossed to fix；During experiment, the lower section grips test platform of testing machine, the top collet of testing machine by ears with it is removable
The mooring ring for unloading formula tie-down point 1 pitches connection by ear, and applies tensile load, it can be achieved that various to detachable tie-down point
The loading of operating mode angle combinations.
The beneficial effects of the invention are as follows：Because the loading direction of testing machine can only keep vertical direction to load always, existing
Fixture can not achieve angular adjustment, therefore can be only done one of which operating mode, it is impossible to realize each operating mode by adjusting component,
The experiment that detachable tie-down point experiment is caused to need many sleeve clamps that could complete all operating modes.The present invention passes through spline
The combination of axis, spline ears seat, chassis realizes the adjustment of operating mode angle beta, and operating mode angle is realized by the combination on chassis, turntable
The adjustment of α is spent, can realize the angle requirement of the various operating modes of detachable tie-down point.The present invention only realizes institute by a set of
Have the demand of operating mode, reduce cost, improve efficiency, at the same take into account experiment loading accuracy, changing the outfit the factors such as facilitates.
