Abstract
The utility model discloses an apparatus for measuring the tension force of a tension spring. The apparatus comprises an electrical control device, a display device, and a mechanical transmission device. The display device comprises a pulling force sensor and a display. The mechanical transmission device comprises slide bars and a slide block. The slide block moves right and left on the slide bars and connects with a synchronous belt. The synchronous belt is arranged between a motor belt wheel and a synchronous belt wheel. The motor belt wheel is connected with a variable frequency motor. The variable frequency motor is connected with a stretching button and a contracting button on a control panel. A first spring draw hook is arranged at the right side of the slide block. A second spring draw hook is arranged at the left side of the right end of the slide bars. The first spring draw hook and the second spring draw hook are leveled with each other. The pulling force sensor is arranged at the second spring draw hook and connected with the display. The apparatus is advantaged by being simple in structure and capable of rapidly and accurately measuring out the tension force of the tension spring.
Description
Technical field
The utility model relates to a kind of extension spring measurement mechanism, relates in particular to a kind of extension spring tension measuring device.
Background technology
The steel cord is strict with monofilament laying tension unanimity in twisting with the fingers burst process, in case the monofilament tension force shakiness of twisting traction when fluctuation is arranged, will cause that the unrelieved stress of steel cord changes, stable tension force is that the important techniques during the steel cord is produced one of requires.What tradition unwrapping wire mode was used is the frictional disk unwrapping wire, can only control the tension force lower limit during work, and the uncontrollable tension force upper limit causes being difficult to control tension stability; This just needs to use another kind of unwrapping wire mode---permanent tension stringing.Monofilament makes tension stability by the elasticity control of self tension force and extension spring during permanent tension stringing, when tension force moment during less than extension spring moment, the I-beam wheel slow rotation, when tension force moment during greater than extension spring moment I-beam wheel can do and accelerate to rotate, the moment that extension spring this moment produces increases gradually reduces extension spring moment gradually, last the two balance at the uniform velocity turns round I-beam wheel.Because crucial effects is played in extension spring in control procedure, so the selection to extension spring requires also very high, necessarily require the consistance of height, extension spring selects not have unified measurement standard in the prior art, unified demand, be artificial selection all, only depend on range estimation, the tension force of the extension spring of selection will be incomplete same.And tension spring tension does not wait and will make the tension force inequality on same unwrapping wire platform, in case the inconsistent meeting of tension force causes the tension force shakiness on the unwrapping wire platform, just needs to arrange the special messenger to regulate, and is time-consuming bothersome.
Summary of the invention
At the problems referred to above, in order to allow the extension spring uniform tension in order of using, prevent from causing the tension force shakiness because of extension spring tension force difference, the utility model provides a kind of extension spring tension measuring device, whether the extension spring tension parameters that it can accurately measure same model is identical, select identical extension spring for use, make permanent tension stringing system not influenced by extension spring, guarantee that unwrapping wire is stable.
Technical solution of the present utility model is as follows: the extension spring tension measuring device, comprise electrical control gear, display device, mechanical driving device, described display device comprises pulling force sensor, display, it is characterized in that: described mechanical driving device comprises slide bar, slide block, described slide block move left and right on slide bar, described slide block is connected with synchronous band, described synchronous band is arranged between electrical machine belt pulley and the synchronous pulley, described electrical machine belt pulley is connected with variable-frequency motor, stretching button on described variable-frequency motor and the control panel, retraction button is connected, the right side of described slide block is provided with first snap clasp, the right-hand member left side of described slide bar is provided with second snap clasp, described first snap clasp and second snap clasp are in same horizontal level, the described second snap clasp place is provided with pulling force sensor, and described pulling force sensor is connected with display.
The bottom of described slide block is provided with and stretches spacingly, shrinks spacingly, and described stretching is spacing, shrinks spacing being arranged on the position limit arm, and described position limit arm is connected with the support of control panel.
The support connection of described position limit arm and control panel is provided with adjusting handle.
When the utility model uses, at control panel mensuration tension force is set, will be detected extension spring and be placed between first snap clasp, second snap clasp, before work, confirm display zero setting.At first by drawing high on the control panel, variable-frequency motor work, variable-frequency motor drives by synchronous band and is moved to the left at slide bar, when the detection red light is bright, have ten seconds time read, the back is by retraction button behind the record data, the variable-frequency motor counter-rotating, move right at slide bar by synchronous band drive, when initial length is got back in detected extension spring, stop automatically, and measure next extension spring tension force.As long as measured value is namely not defective at specialized range extension spring tension force.
The utility model is provided with and stretches spacingly, shrinks spacingly, prevents from stretching and extension spring no to scale during contraction.
The utility model is compared with prior art: unique in the whole process link of artificial factor is arranged is exactly reading, with respect to originally distinguishing with people's naked eyes, measuring accuracy has had the difference of matter, thereby the utility model can be quick, select qualified extension spring accurately, solve the trouble and worry of professional production.
