Description
Technical field
The utility model relates to a kind of control device of stepping motor absolute zero position, the absolute zero position control device of especially a kind of stepping motor when driving drive system belongs to Stepping Motor Control.
Background technology
Stepping motor is a kind of control motor that pulse signal is become straight-line displacement and angular displacement, since its rotating speed and displacement strictly with the umber of pulse correspondence, so control is simple, can be widely used in the automatic control system, as executive component, be one of critical product of electromechanical integration.In use, stepping motor mostly is open loop control, though higher positional precision is arranged, but require its absolute zero position control is difficult to accomplish, generally must use closed circuit control, just can accomplish, method commonly used is to add photoelectric encoder or resolver on the rear axle of motor, zero signal according to transducer spreads out of carries out discriminating processing to controller.But costing an arm and a leg of photoelectric encoder or resolver only is used for the measuring ability of a zero signal, and its cost performance is too high, is unfavorable for applying.It is very extensive to use stepping motor at present in economical NC machine tool, its Stroke Control is provided with as judges to sensing equipment near switch, optoelectronic switch or the conduct of other travel switch the coarse positioning of transmission mostly at the not end of drive system, its precision is not high, can not satisfy the required precision of machine tooling far away, generally in use for reaching processing request, must carry out tool setting earlier, start-up routine is processed then, but so too time-consuming, efficient is not high.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provides a kind of simple in structure, and cost is low, can make things convenient for the stepping motor absolute zero position control device of the absolute zero position of control step motor.It comprises that a stepping motor by controller control reaches the drive system by its drive, be provided with sensing equipment and link to each other at the end position of drive system with controller, the armature spindle of stepping motor is provided with the orientation sensing device, and this orientation sensing device is connected with controller.
Described orientation sensing device comprises the fixing photoelectric sensor that is fixed in the chip that has narrow groove on the armature spindle and matches, and photoelectric sensor is to face the chip fixed in position.
Described photoelectric sensor is built-in with shaping or amplifying circuit, and the narrow groove on the described chip is axially to be provided with.
The utility model compared with prior art, have simple and reliable for structure, characteristics such as cost is low, and the absolute zero position of control step motor is widely used easily, and is easy to utilize.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, stepping motor absolute zero position control device described in the utility model, it comprises the drive system 2 that a stepping motor 1 of being controlled by controller reaches by its drive, drive system shown in the figure by the screw mandrel 3 that links to each other with stepping motor 1 with by fixedlying connected with the travelling gear of screw mandrel engagement, movably planker 4 is formed, end position in drive system, be that the displacement of planker 4 is not held and is provided with inversion sensing device 5, as coarse positioning transducer or optoelectronic switch or travel switch etc., should link to each other with controller to level sensor 5, accept the coarse positioning that putting in place of drive system 2 slightly declared signal and control step motor 1 by controller.The armature spindle 6 of stepping motor 1 is provided with orientation sensing device 7, this orientation sensing device 7 comprises the fixing photoelectric sensor 10 that is fixed in the chip 9 that has narrow groove 8 on the armature spindle 6 and matches, the precise judgement signal that utilizes the groove edge of photosignal on chip 9 of photoelectric sensor 10 to beam back transfers to controller, to judge radially absolute zero position of armature spindle, and the fine positioning of control step motor 1, i.e. absolute zero position.The utility model mainly is to utilize slightly to declare signal, and the coarse positioning of control step motor 1 judges promptly which circle rotor axis of electric is positioned at; The precise judgement signal that utilizes chip groove edge fixing on the rotor axis of electric to send, the fine positioning of control step motor judges that promptly the stepping motor rotor axle is positioned at which point in the thick fixed circle, i.e. absolute zero position.
The utility model is fixed with the chip 9 that has narrow groove 8 on the rear axle section of stretching out of the armature spindle 6 of described stepping motor 1, be furnished with the photoelectric sensor 10 that is fixed on the stepping motor rear end cap relevant position mutually with chip 9.This photoelectric sensor 10 is to face chip 9 fixed in position, and it is built-in with shaping or magnification circuit plate, and the narrow groove 8 on the described chip 9 is axially to be provided with.When the stepping motor band chip 9 rotations, during the chip 9 shading light signals of telecommunication low level 0 output; When aiming at narrow groove 8, the signal output of 24V amplitude is just arranged, controller detects this signal, allows the stepping motor stop, owing to be the edge-triggered of seam, so positioning accuracy is very high, realizes the location of absolute zero position easily.
