A drive shaft is arranged in tension sensor bottom, and movable ram is provided with below the drive shaft, and the movable ram is equipped with blind
Hole, the drive shaft and blind hole are slidably matched, and drive shaft is equipped with one for detecting drive shaft bottom end position opposite with movable ram
The position sensor set, movable ram are arranged right below branch fastener, and the branch fastener is fixed on the base.
Further, when the drive shaft moves downwardly to blind via bottom under driving plate effect, the position sensor
It is triggered.
Further, it is equipped with guiding axis below the driving plate, described guiding axis one end is fixedly connected with driving plate, another
End is in free state, is equipped with guide plate on the movable ram, the guide plate and guiding axis are slidably matched.
Further, the guiding axis bottom is equipped with the stop nut for preventing movable ram from falling.
Further, one is equipped in the drive shaft to install in the sensor that short transverse carries out position adjusting
Block, the position sensor are installed on sensor mounting blocks, position sensor probe face guide plate.
Further, the driving mechanism is driven using DC servo motor cooperation speed reducer and T-type threaded screw rod structure
Movable plate realizes elevating movement under the driving of T-type threaded screw rod.
The utility model has the beneficial effects that
The utility model carries out cooperation by the blind hole of the drive shaft and movable ram that are arranged and realizes initial alignment, is positioning
Initial stage, after sample is placed, movable ram can free-falling to the position that is bonded with sample, then driving mechanism moves down drive shaft
To being automatically stopped when being bonded with blind hole bottom surface, initial position is determined at this time, when drive shaft continues to push, can push activity
Pressure head compresses sample, simple to operate so as to accurately determine sample compression deformation under a certain pressure,
Measuring accuracy can be effectively improved.

Specific embodiment
With reference to the drawings and specific embodiments, the utility model is described in further detail.It should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model.In addition, it should also be understood that, having read the utility model instruction
Content after, those skilled in the art can make various changes or modifications the utility model, and such equivalent forms are equally fallen
In range defined herein.
As shown in Figures 1 to 3, the utility model is a kind of plastic draining belt core ribbon pressure flexor strength analyzer, for measuring modeling
Expect the pressure flexor strength of drainage belt core ribbon, also can measure the compression of the materials such as textile, leather, laminate, rubber, thread yarn, cotton rope
Performance test.
This analyzer mainly includes pedestal 9, is equipped with vertical rail 2 and driving mechanism on pedestal 9 vertically, on vertical rail 2
Equipped with liftable driving plate 4 is driven by driving mechanism, particularly driving mechanism include a DC servo motor 1, with it is straight
The accurate retarding machine that flow servo motor 1 connects, accurate retarding machine drive a T-type thread lead screw 3 to rotate, driving plate 4 and T-type spiral shell
Line lead screw 3 is threadedly engaged, under the driving of motor 1, elevating movement of the control driving plate 4 in short transverse.
A tension sensor 5 is arranged in 4 bottom of driving plate, and a drive shaft 6, tension sensor 5 is arranged in 5 bottom of tension sensor
For measuring 6 pressure applied value of drive shaft.Movable ram 7 is provided with below drive shaft 6, movable ram 7 is equipped with blind hole
