Abstract
The utility model discloses a shearing apparatus, it includes workstation, motor, worm gear case, shearing box, dynamometry ring and kicking block on the workstation, the motor is connected with the worm gear case transmission, and the worm gear case is equipped with the telescopic apical axis for shearing box one side, the motor is step motor. The shearing machine also comprises a control device, and the control device is electrically connected with the stepping motor. In the structure, the motor adopts the stepping motor, so that the rotating speed of the motor is slow enough, then the moving speeds of the force measuring ring and the shearing box are slow enough when the shearing instrument works, the speed is lower than 0.02 mm/s, and the working precision of the shearing instrument is ensured. In addition, the control device is connected to the shearing instrument, the rotating speed of the motor can be controlled according to different loads of the motor, and when the loads are increased continuously, the rotating speed of the motor is reduced continuously, so that the controllability of the shearing instrument is improved, and the convenience in use is improved.
Description
Technical field
The utility model relates to a kind of test apparatus, especially a kind of boxshear apparatus that is used to detect soil property.
Background technology
The soil analysis that boxshear apparatus is widely used in building as a kind of geotechnological detecting instrument, existing boxshear apparatus is generally electronic tetrad direct shear apparatus, it comprises worktable, the motor on worktable, worm gear case, shear box, proving ring and jacking block, jacking block is fixed on the worktable, motor and worm gear case are in transmission connection, and worm gear case is provided with telescopic apical axis with respect to shear box one side.During boxshear apparatus work, the material of required detection is put into shear box, the axle that drives in the worm gear case by the driven by motor chain drive rotates, the apical axis of worm gear case is stretched out to the shear box direction, constantly promote shear box, shear box promotes proving ring again, because the other end of proving ring is the jacking block that is fixed on the worktable, cause the shear box distortion, break, measure the shear parameters of detected material then according to the reading of proving ring until detected material.In general, the movement velocity of proving ring, shear box wants enough could guarantee slowly the precision of boxshear apparatus work during boxshear apparatus work, the speed that this kind boxshear apparatus promotes proving ring, shear box relies on the adjusting rotating speed of motor to realize, is to rely on frequency conversion to finish mostly and regulate rotating speed.Therefore the problem one of its existence is that the speed that is difficult to control when shearing is lower than 0.02 mm/second, has influenced the operating accuracy of boxshear apparatus; The 2nd, control device is complete inadequately, has influenced the convenience that boxshear apparatus uses.
The utility model content
At the problems referred to above, it is low that the problem that the utility model quasi-solution is determined provides a kind of speed of controlling when shearing, the operating accuracy height, and control device is complete, the boxshear apparatus easily of use.
For addressing the above problem, the utility model has adopted following technical scheme: a kind of boxshear apparatus, comprise worktable, motor, the worm gear case on worktable, shear box, proving ring and jacking block, described motor and worm gear case are in transmission connection, worm gear case is provided with telescopic apical axis with respect to shear box one side, and described motor is a stepper motor.
Above-mentioned boxshear apparatus, it also comprises control device, described control device is electrically connected with described stepper motor.
Owing to adopted said structure, motor has adopted stepper motor, makes rotating speed of motor enough slow, and the movement velocity of proving ring, shear box wanted enough slow when boxshear apparatus was worked then, and its speed is lower than 0.02 mm/second, can guarantee the precision of boxshear apparatus work like this.In addition, connect control device on boxshear apparatus, he can control its rotating speed when the different load according to motor, and when load continued to increase, rotating speed of motor constantly reduced, and improved the controllability that makes boxshear apparatus, has increased the convenience of using.
Description of drawings
Fig. 1 is the structural representation of boxshear apparatus of the present utility model.
Among the figure: 1-motor, 2-worm gear case, 3-shear box, 4-proving ring, 5-jacking block, 6-control device, 7-apical axis, 8-worktable.
Embodiment
As shown in Figure 1, boxshear apparatus of the present utility model, comprise worktable 8, motor 1, the worm gear case on worktable 82, shear box 3, proving ring 4 and jacking block 5, jacking block 5 is fixed on the worktable, described motor 1 is in transmission connection with worm gear case 2, worm gear case 2 is provided with telescopic apical axis 7 with respect to shear box 3 one sides, and as improvement of the present utility model, described motor 1 is a stepper motor.Present embodiment be the double shear instrument, both under same motor 1 drives, two worm gear cases 2, shear box 3, proving ring 4 and jacking block 5 were arranged.Certainly can also be to cut that instrument or three is cut or simple shear etc.
Boxshear apparatus work of the present utility model is as follows: the material of required detection is put into shear box 3, drive in the worm gear case 2 axle rotates by motor 1, the apical axis 7 of worm gear case is stretched out to shear box 3 directions, constantly promote shear box 3, shear box 3 promotes proving ring 4 again, because the other end of proving ring 4 is to be fixed on the worktable 8 jacking block 5, causes shear box 3 distortion, break until detected material, measure the shear parameters of detected material then according to the reading of proving ring 4.Owing to adopted stepper motor 1, make rotating speed of motor enough slow, the movement velocity of proving ring 4, shear box 3 wanted enough slow when boxshear apparatus was worked then, and its speed is lower than 0.02 mm/second, has guaranteed the precision of boxshear apparatus work.
As improvement, boxshear apparatus of the present utility model also comprises control device 6, and described control device 6 is electrically connected with described stepper motor 1.Connect control device 6 on boxshear apparatus, he can control its rotating speed when the different load according to motor 1, and when load continued to increase, rotating speed of motor constantly reduced, and like this, improved the controllability that makes boxshear apparatus, had increased the convenience of using.
