And between load bar 25, exported by the guiding of guide post 23, to ensure that the axially loaded power of actuator 22 is more smoothly transmitted
To load bar 25.
Further, described load bar 25 is provided with the second rod end axle near the body of rod of ball pin 16 one end of described swing arm 11
Bearing 254, the lower end of described control bar 26 is provided with the second rod end bearing 261 being connected with described second rod end bearing seat 254.?
In the present embodiment, this second rod end bearing seat 254 is by being available for rectangular through holes that described second rod end bearing 261 inserts and vertical
In the center of rectangular through holes and be available for securing member through and the second rod end bearing 261 is connected in rectangular through holes
Manhole is constituted.The top of described control bar fixed support 27 is provided with the 3rd rod end bearing seat 271, described control bar 26 upper
End is provided with the 3rd rod end bearing 262 being connected with described 3rd rod end bearing seat 271.It should be noted that owing to controlling bar 26
Be respectively arranged at two ends with rod end bearing up and down so that control bar 26 become two power bars, with avoid control bar 26 produce moment of flexure and footpath
Xiang Li, simultaneously works as preventing the effect of swing arm about 11 play, improves the swing arm unidirectional loading of single shaft fatigue test-bed further
Stability.
More preferably, the hinged center of described control bar 26 lower end, described swing arm 11 ball pin 16 center all with described loading
The body axis of bar 25 overlaps, to avoid generation radial load and load bar 25 to rotate.
More preferably, described guide post 23 is coaxially disposed with described actuator 22, whole to ensure the loading force of actuator 22
Act on guide post 23, and promote load bar 25 that swing arm 11 is loaded, during, actuator 22 does not produce other direction
Component.
Each pin joint above-mentioned, such as the first hinged seat 212 and the first ball pivot the 221, second hinged seat 231 and the second ball pivot
222, the first rod end bearing seat 232 and first rod end bearing the 251, second rod end bearing seat 254 and the second rod end bearing 261,
The ball pins 16 of three rod end bearing seats 271 and the 3rd rod end bearing 262, the installing hole 253 of load bar 25 front end and swing arm 11 etc. are equal
Linked together by bolt or the securing member such as screw or nut, it is achieved each leverage is freely rotatable around respective hinged center.
The operation principle of swing arm single shaft fatigue test-bed of the present utility model is as follows:
The loading head of actuator 22 travels forward, and promotes guide post 23, and guide post 23 promotes load bar 25, load bar 25 to push away
The ball pin 16 of movable pendulum arm 11, ball pin 16 stand under load.Otherwise, the loading head rearward movement of actuator 22, pull guide post 23, guide post
23 pull load bar 25, load bar 25 to pull the ball pin 16 of swing arm 11, ball pin 16 stand under load.
Before and after the ball pin 16 of swing arm 11 in motor process, it is possible to swing up and down.Control the lower end of bar 26 with load bar
25 motions, are also the 3rd rod end bearing 262 pivot around the upper end controlling bar 26.So, the ball pin 16 of swing arm 11 is front
Rear motor process has slight up and down motion, but what the most controlled bar 26 controlled, displacement is sufficiently small, the most anti-
Only swing arm swings along non-load direction, improves loading stationarity.
Shown in Figure 8, when actuator 22, guide post 23, load bar 25 are rotated certain angle around the ball pin 16 of swing arm 11
Degree, such as 90 °, can realize X conversion between loading and Y-direction load, and loading direction can the most quickly adjust, and without separately
Outer making test-bed and fixture, adjust simple and practical.
In sum, swing arm single shaft fatigue test-bed of the present utility model is by actuator 22, guide post 23, load bar 25
With control bar 26 be grouped together formation one can uniaxial loading system smoothly, can be efficiently quick the most right in one direction
Swing arm 11 is tested, its simple in construction, easily realizes.
Above disclosed only preferred embodiment of the present utility model, can not limit this practicality with this new certainly
The interest field of type, the equivalent variations therefore made according to this utility model claim, still belong to this utility model and contained
Scope.
