Description
Technical field
The present invention relates to material testing apparatus field, be specially one contact warning charger and using method thereof.
Background technology
The rigidity test of material is important indicator for the material property of workpiece.Material may go out under different load
Existing different deformation, thus show different rigidity characteristics.More existing test equipment be for material be continuously applied by
Cumulative big load, and measure the deflection of generation during the course.Due to dynamic and the instantaneity of measurement of load variations,
This mode easily causes measurement error.And in the equipment for fixed value formula imposed load, due to the discreteness of fixed value, because of
This some position performance being difficult to obtain expected value at any time.And, during the holding of fixed value, it is susceptible to load slight fluctuations,
Thus cause measurement error.And though some equipment ensure that certainty of measurement, relatively costly, maintenance work is multiple
Miscellaneous.
Summary of the invention
It is an object of the invention to provide a kind of contact warning charger and using method thereof, it is possible to solve existing skill
Problem in art.
By the contact warning charger of the present invention, including frame, the loading that can move left and right in described frame

Closing, the right-hand member of described rotary shaft couples with the outputting axial power driving motor on the boss right flank being installed on described frame,
From a left side, the right side is provided with two roll wheel assemblies in the downside of described loading dolly, and each described roll wheel assembly all includes by unilateral bearing
Install and in order to the roller engaged with described frame, thus roll with described frame when described roller rotates and coordinate with to described
The motion loading dolly guides, and coordinates with described frame to stop the motion of described loading dolly, often when fixing
Individual described roll wheel assembly also includes the slide lock locking member for coordinating, each described cunning with the outer ring periphery of described unilateral bearing
Dynamic locking piece is all connected with respective retracted for clearance spring, and downside is provided with for the outer ring circle with corresponding unilateral bearing
The locking liner that side face engages, upper side end is provided with inclined plane part, and wherein, described loading dolly also includes along described loading dolly
Longitudinal direction and the operation bar that extends, the left part of described operation bar is positioned on two described slide lock locking member, and sets with left and right
Two the described slide lock locking member corresponding positions put are respectively arranged with left pushing and withstanding wedge portion's section and right pushing and withstanding wedge portion section, institute
State the left and right sides of left pushing and withstanding wedge portion section to be respectively left withdrawal par and a left side and back down par, described right pushing and withstanding wedge portion section
The left and right sides be respectively right withdrawal par and the right side and back down par, the right part of described operation bar is slide-and-guide portion, in order to
Being slidably matched with the inner chamber of external thread sleeve, the middle part of described operation bar is provided with operation and protrudes in order to operate described operation bar
Side-to-side movement, thus, when described operation bar moves in left position, par is backed down on a described left side and par is backed down respectively in the right side
Coordinate with the inclined plane part of corresponding slide lock locking member thus slide lock locking member is pushed the outer ring circle engaging corresponding unilateral bearing
Side face, now, described unilateral bearing only allows described loading dolly to left movement and stop institute under the driving of described rotary shaft
State and load moving right of dolly；When described operation bar moves in right position, described left withdrawal par and right withdrawal are put down
Smooth portion coordinates with the inclined plane part of corresponding slide lock locking member respectively thus will slide under the effect of respective retracted for clearance spring
Locking piece disengages with the outer ring periphery of corresponding unilateral bearing, and now, described loading dolly is allowed to side-to-side movement；Wherein,
The upside of described loading dolly can be provided with pushing and withstanding slide block slidably, the left side of described pushing and withstanding slide block be used for engaging described workpiece with
Carrying out test to load, the right side of described pushing and withstanding slide block is connected with the top pressure spring pressed on car top protrusion, described pushing and withstanding
The left side of slide block is provided with touch sensor, is additionally provided with alarm at described frame left end, and described alarm contacts with described

Alarm sends the sound of alarm, carries out to be pointed out described pushing and withstanding slide block to be in described workpiece engaged by sound
Test stress state, then represents when described alarm does not send the sound of alarm at described pushing and withstanding slide block and described workpiece
In disengaged position.
According to the present invention, the using method of above-mentioned contact warning charger, first, by described clamping workpiece in institute
State on clamping bench, and described operation bar is moved to described in left position, so that described loading dolly is only permitted and transports to the left
Dynamic, under the driving effect of described driving motor, described loading dolly is gradually to left movement, when described pushing and withstanding slide block is to described work
When the load that part applies reaches the first level, described loading dolly stop motion is so that the load of described first level keeps
Certain time；Afterwards, described loading dolly continues to left movement, so that the load that pushing and withstanding slide block applies to described workpiece reaches
To the second level and keep certain time；When described workpiece is unloaded by needs, operate described operation bar thus it is positioned at described
In right position, in order to allow described driving motor that described loading dolly is driven such that to the right described pushing and withstanding slide block and described work
Part departs from.
By such scheme, due to take can the roller of single roll, and this one-way performance is to handle solution
Remove, thereby it is ensured that after operation possesses this one-way performance, it is possible to workpiece is realized the load of monotone increasing, and
And this load can apply keep constant and continue the desired time period.This has the advantage that for measuring accurate deflection.
Then can allow for material is unloaded by releasing this one-way performance.
