[embodiment]
As shown in Figure 1, 2, the anchor clamps that connect mobile phone hinge comprise anchor clamps 3 and lower clamp 4, and stepper motor 1 is connected with an end of last anchor clamps 3 by first shaft coupling 2, rotate with stepper motor 1 to drive anchor clamps 3.The other end of last anchor clamps 3 inwardly has a groove 31, and close at the hinge position 32 that the shape of groove 31 and the degree of depth are connected with the upper casing of mobile phone shape mutually, is used for the hinge position 32 that the upper casing with mobile phone connects and snaps in, and rotates with the hinge position that the upper casing that drives mobile phone connects.Lower clamp 4 one ends inwardly have a groove 41, close at the hinge position 42 that the shape of groove and the degree of depth are connected with the drain pan of mobile phone shape mutually, be used for that the drain pan of mobile phone is connected 42 hinge position and snap in, the other end of lower clamp is connected with torque sensor 6 by second shaft coupling 5.Anchor clamps can be changed according to the different size mobile phone hinge in complete analogue mobile phone upper casing of the groove of last lower clamp and drain pan hinge installation position, and go up lower clamp and leave enough spaces, and are also applicable as the rotary gemel that the need measuring height is higher.The torsion that lower clamp 4 bears the hinge position 42 of the drain pan connection of mobile phone passes to torque sensor 6, torque sensor 6 changes the torque axis of perception into electric signal, and be transferred to torsion-testing result treatment parts 7 by shielded cable 105, as Fig. 3, shown in 4, torsion-testing result treatment parts 7 can be torductors 104, torductor 104 provides reference power supply for torque sensor 6, label 103 expression Switching Power Supplies among Fig. 4, the electric signal that 104 pairs of torque sensors 6 of while torductor are converted to is gathered, and the result that will gather to send to controller 101, the first communication interfaces 8 by first communication interface 8 can be the RS232 interface.Torductor comprises also is used for the alarm element of reporting to the police that when the torsion-testing result exceeds bound when moment of torsion exceeded upper and lower limit, measuring instrument was given controller with output alarm signal, sends chimes of doom simultaneously.Controller 101 is electrically connected with stepper motor 1, and control step motor 1 is according to the stepping angular turn of setting.Controller 101 also is connected with host computer 102 by second communication interface 9, and second communication interface 9 can be the RS232 interface, and host computer can be computer PC, and controller comprises programming controller PLC and the power amplifier that links to each other with programming controller PLC.Controller divides 180 degree, 270 degree and three kinds of angle measurements of 360 degree as requested; Utilize stepper motor stepping angle location accurately, can do the moment of torsion collection of 200 points (uniform distribution) to three kinds of angles.When selecting 180 degree tests (other angles are by that analogy), revolution 0.9 degree carries out a moment of torsion collection under the control of controller, and is stored on the controller, treat that 200 points test after; 200 record values can be sent to PC once; For the protection to precision measuring instrument, at test process, when moment of torsion is reported to the police, controller will be controlled motor and return initial point.The circuit diagram of controller and motor as shown in Figure 5, the X0-X6 of figure middle controller is the input end of operational order, Y0-Y5 is the output terminal of controller control; Power amplifier is used for the output power of controller is amplified, and guarantees the driving force to load.Step-by-step impulse Y0 and step direction Y2 input to stepper motor driver behind current-limiting resistor voltage divider R, and control motor corner and turn to.
Controller also comprises selector switch K, as shown in Figure 6, is used for conversion between first communication interface 8 and second communication interface 9, to select the communication between definite controller and torductor or the PC.
As shown in Figure 4, present embodiment uses the AC220V power supply, starts the back power supply directly to the torductor power supply, and gives controller, power board and stepper motor driver power supply after " Switching Power Supply " is converted to DC24V.
When testing for convenience mobile phone hinge put into lower clamp, the support 11 and the guidepost 12 that are used to load stepper motor have also been designed, as shown in Figure 3, support 11 ring sets are on guidepost 12 and can slide along guidepost 12, the track that guidepost 12 and last anchor clamps 3 are moved during away from lower clamp 4 is parallel, and guidepost 12 is 2 or three.Has lifting rod 13 on the support 11, slide up and down at the effect lower edge of lifting rod 13 guidepost 12, its effect is that anchor clamps 3 are risen, thereby get out of the way the space of mobile phone hinge being put into lower clamp 4, after hinge is put into lower clamp 4, put down anchor clamps 3, thereby make the hinge two ends be loaded on the clamping of realizing mobile phone hinge in the lower clamp respectively.
Before test, selector switch should be pulled out to receiving position, promptly is communicated with torductor, and carry out data transmission between controller and the torductor this moment; After test is finished, open the hyper terminal of WINDOWS earlier, and the examination of communication lattice is set to: COM1, bits per second: 9600, data bit: 8, parity checking: do not have position of rest: 1, data flow con-trol: hardware; Then selector switch is pulled out to sending the position, by " data transmission " knob, this moment, controller sent to host computer with 200 record values, and can save as the host computer file.The data that host computer is received copy to Excel software and can draw out the distribution curve of moment of torsion and analyze.
