Description

A kind of portable charger and using method thereof
Technical field
The present invention relates to material testing apparatus field, be specially a kind of portable charger and using method thereof.
Background technology
The rigidity test of material is important indicator for the material property of workpiece.Material is likely to occur different deformation under different load, thus shows different rigidity characteristics.More existing test equipment are material to be continuously applied to the load being gradually increased, 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, therefore, it is difficult to obtain the some position performance of expected value at any time.And, during the holding of fixed value, it is susceptible to load slight fluctuations, thus causes measurement error.And though some equipment ensure that certainty of measurement, relatively costly, maintenance work is complicated.
Summary of the invention
It is an object of the invention to provide a kind of portable charger and using method thereof, it is possible to solve the problems of the prior art.
nullBy the portable charger of the present invention,Including frame、Can move left and right in described frame loads dolly and is fixed at described frame left end the clamping bench for clamping workpiece,Wherein,The right side of described loading dolly is fixedly connected with external thread sleeve in order to stretch into the hollow inside of rotary shaft the female thread ring portion threaded engagement with described rotary shaft left end,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,Each described roll wheel assembly all includes being installed by unilateral bearing and in order to the roller engaged with described frame,Thus coordinate with the rolling of described frame when described roller rotates and guide with the motion to described loading dolly,And coordinate with described frame to stop the motion of described loading dolly when fixing,Each described roll wheel assembly also includes the slide lock locking member for coordinating with the outer ring periphery of described unilateral bearing,Each described slide lock locking member is all connected with respective retracted for clearance spring,And downside is provided with the locking liner for engaging with the outer ring periphery of corresponding unilateral bearing,Upper side end is provided with inclined plane part,Wherein,Described loading dolly also includes the operation bar extended along the longitudinal direction of described loading dolly,The left part of described operation bar is positioned on two described slide lock locking member,And two the described slide lock locking member corresponding positions arranged with left and right are respectively arranged with left pushing and withstanding wedge portion's section and right pushing and withstanding wedge portion section,The left and right sides of described left pushing and withstanding wedge portion section is respectively left withdrawal par and par is backed down on a left side,The left and right sides of described right pushing and withstanding wedge portion section is respectively right withdrawal par and par is backed down on the right side,The right part of described operation bar is slide-and-guide portion,It is slidably matched in order to the inner chamber with external thread sleeve,The middle part of described operation bar is provided with operation and protrudes in order to the side-to-side movement operating described operation bar,Thus,When described operation bar moves in left position,Par is backed down on a described left side and right par of backing down coordinates with the inclined plane part of corresponding slide lock locking member thus respectively by the outer ring periphery of unilateral bearing corresponding for slide lock locking member pushing joint,Now,Described unilateral bearing only allows described loading dolly to left movement and stop moving right of described loading dolly under the driving of described rotary shaft;When described operation bar moves in right position, described left withdrawal par and right withdrawal par coordinate with the inclined plane part of corresponding slide lock locking member respectively thus are disengaged by the outer ring periphery of slide lock locking member with corresponding unilateral bearing under the effect of respective retracted for clearance spring, 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 is used for engaging described workpiece and loads to carry out test, the right side of described pushing and withstanding slide block is connected with the top pressure spring pressed on car top protrusion, the bottom of described frame is provided with the roller mount of more than four, it is provided with movable pulley in described roller mount, being additionally provided with for limiting the limit switch that described movable pulley rolls in described roller mount, described movable pulley conveniently makes this device can running transform position as required in order to drive described machine frame movement.
According to the present invention, the using method of above-mentioned portable charger, first, by described clamping workpiece on described clamping bench, and described operation bar is moved to described in left position, so that described loading dolly is only permitted to left movement, under the driving effect of described driving motor, described loading dolly is gradually to left movement, when described pushing and withstanding slide block reaches the first level to the load that described workpiece applies, 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 pushing and withstanding slide block reaches the second level to the load that described workpiece applies and keeps 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 described pushing and withstanding slide block departs from described workpiece to allow described driving motor to be driven such that to the right by described loading dolly.
Pass through such scheme, can the roller of single roll owing to taking, and this one-way performance can handle releasing, therefore, ensure that after operation possesses this one-way performance, workpiece can be realized the load of monotone increasing, 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.
