Abstract
Disclosed is a semiautomatic scanning control device applicable to complex profile eddy current detection. A single chip microcomputer is connected with a driving circuit, the driving circuit is connected with a power amplifier circuit connected with a stepping motor, the stepping motor is connected with one end of a lead screw, one end of a fixing board is in fit connection with the surface of the lead screw, and a probe is connected to the other end of the fixing board. The semiautomatic scanning control device has the advantages that the device is stable in running, lift-off effect caused by manual detection is reduced, detection signals are more stable and accurate, detection omission due to human factors can be avoided, and detection efficiency is further greatly increased.
Description
Technical field
The utility model relates to a kind of scanning control device, relates in particular to a kind of semi-automatic scanning control device that is applicable to the complex profile EDDY CURRENT.
Background technology
When implementing EDDY CURRENT, manual detection exists the influence of many subjective and objective factors usually, for example operator's experience, detect gimmick etc., and carrying out complex profile when detecting, artificial scanning meeting causes more error and omission hidden danger.
Summary of the invention
The purpose of this utility model has been to provide a kind of semi-automatic scanning control device that is applicable to the complex profile EDDY CURRENT, has solved when carrying out the complex profile detection the artificial inaccurate problem of scanning.
The utility model is achieved like this, it comprises single-chip microcomputer, driving circuit, power amplification circuit, stepper motor, screw mandrel, probe, it is characterized in that single-chip microcomputer connects driving circuit, driving circuit connects power amplification circuit, power amplification circuit connects stepper motor, stepper motor connects an end of screw mandrel, and the surface engagement of screw mandrel is connected and fixed an end of plate, and the other end of fixed head is connected with probe.
The preferred p-m step motor of described stepper motor.
Technique effect of the present utility model is: operate steadily, reduced to make detection signal accurately stable more owing to manually detecting the Lift-off effect that brings, and the omission situation generation of human factor can not occur, also improved the efficient that detects greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Single-chip microcomputer 2, driving circuit 3, power amplification circuit 4, stepper motor 5, screw mandrel 6, fixed head 7, probe in the drawings, 1,
Embodiment
As shown in Figure 1, the utility model is achieved like this, single-chip microcomputer 1 connects driving circuit 2, driving circuit 2 connects power amplification circuit 3, power amplification circuit 3 connects stepper motor 4, stepper motor 4 connects an end of screw mandrel 5, the surface engagement of screw mandrel is connected and fixed an end of plate, the other end of fixed head is connected with probe, stepper motor 4 preferred p-m step motors, and stepper motor 4 is digital control motors, it becomes angular displacement with shift pulse signal, promptly give a pulse signal, stepper motor 4 just rotates an angle, therefore is very suitable for single-chip microcomputer 1 control.Turning to of control step motor 4, if given working method positive sequence commutation energising, stepper motor just changes, the counter-rotating if inverted sequence is switched on.The speed of control step motor, if send out a gating pulse to stepper motor, it just changes a step, sends out a pulse again, it can change a step again.The interval of two pulses is short more, and the rotating speed of stepper motor is just fast more.
