There is vertical rod in the frame below boosting-rod, vertical rod is set upward, and first pressure receptor is linked below vertical rod,
First pressure receptor connects control device.
Further speaking, there is upward vertical survey chi in centre position on the table, and vertical survey chi is connected with vertically
Displacement receptor, displacement receptor connection control device, there be second pressure receptor, second pressure sense in described arm of force centre
Receiver connects control device.
Further speaking, there are two sliding blocks on slideway, be left slider and right sliding block respectively, sliding block can be left on slideway
Right slip, there is groove above sliding block, also place alignment pin in a groove, alignment pin may be inserted into the earhole of leaf spring,
Described groove direction and slideway direction is vertical, there is left dislocation receptor in left slider, there is right displacement receptor, institute in right sliding block
Left dislocation receptor, the right displacement receptor connection control device stated.
Further speaking, described piston is electric cylinders.
The beneficial effects of the utility model are：Such leaf spring fatigue strength test device can be carried out to the fatigue strength of leaf spring
Test, reach the effect for more comprehensively weighing leaf spring quality index.
There is upward vertical survey chi in centre position in frame, can test the deflection of leaf spring；
Described left dislocation receptor, right displacement receptor, can also test the left and right displacement of leaf spring, more comprehensively weigh plate
The index of spring.
Described piston is electric cylinders, also with accurate measurement the advantages of.
Brief description of the drawings
Fig. 1 is side structure schematic diagram of the present utility model.
Wherein；1st, frame 2, slideway 3, the arm of force 4, boosting-rod 5, piston 6, counter 7, vertical rod 8,
One pressoreceptor 9, vertical survey chi 10, vertical displacement receptor 11, second pressure receptor 12, left slider
13rd, right sliding block 14, alignment pin 15, leaf spring 16, left dislocation receptor 17, right displacement receptor 18, control device.
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, leaf spring fatigue strength test device, it includes a frame 1, it is characterized in that：In described frame
Face has the slideway 2 for placing leaf spring；

Connect motor, motor connection control device 18；
Counter 6, piston operation are also installed in piston side, and counter can count, counter connection control device；
There is vertical rod 7 in the frame below boosting-rod, vertical rod is set upward, and first pressure receptor 8 is connect below vertical rod,
First pressure receptor connects control device 18.
The utility model is in use, leaf spring 15 is placed on slideway, motor operation, in the presence of bent axle, boosting-rod
Operation downwards is come and gone, constantly presses, unclamp to leaf spring, repeatedly come and go, can typically be reached hundreds thousand of times, counter can determine secondary
Number, when leaf spring damages, will be broken, and the pressure that at this moment first pressure receptor is experienced has a larger change, and first
Such impression is passed to control device by pressure experience, is recorded data at this moment, is completed this test.
Further speaking, there is upward vertical survey chi 9 in centre position in frame, and vertical survey chi is connected with vertical position
Shifting receptor 10, vertical displacement receptor connection control device, described arm of force centre also second pressure receptor 11, second
Pressoreceptor connects control device.
So, the deflection of leaf spring under a certain pressure can be tested.
Further speaking, there are two sliding blocks on slideway, be left slider 12 and right sliding block 13 respectively, sliding block can be in slideway
On horizontally slip, there is groove above sliding block, also place alignment pin 14 in a groove, alignment pin may be inserted into the ear of leaf spring
Kong Zhong, described groove direction and slideway direction are vertical, there is left dislocation receptor 16 in left slider, there is right displacement sense in right sliding block
Receiver 17, described left dislocation receptor 16, right displacement receptor 17 connection control device.
Specific embodiment of the utility model is the foregoing is only, but architectural feature of the present utility model is not limited to this,
Any those skilled in the art in field of the present utility model, all cover of the present utility model by the change or modification made
