Description
Technical field
The utility model relates to Linear actuator field, particularly a kind of smart linear driver with stroke control function.
Background technology
Existing Linear actuator is all with travel switch, the stroke dimension of control and drive system is carried out by travel switch, operation principle driver is provided with 2 travel switches, the stretching, extension of difference control and drive system and contraction size, driver is stretching or contractile motion, driver and stop motion when touching corresponding travel switch, thus realize the control of stroke dimension.But there are 3 major defects in this mode:
1, this mode needs on the pusher bar support of driver, be designed for the locus of placing travel switch, and travel switch is arranged on pusher bar support, because the position dimension between pusher bar support and 2 travel switches has deviation in the course of processing, the precision of the stroke dimension when real work is often caused to be difficult to control.
2, the stroke dimension of this mode is determined by the position of travel switch, and when driver just can not must be taken apart the position of rear change travel switch to reach the unification with household size during proper engagement with the size of the household coordinated because of scale error by stroke dimension, this process cannot must return factory in the realization of client there and carry out the transformation of the way of doing over again.
3, the circuit of this mode is normally designed to the circuit connected in series of travel switch and motor, the larger current that motor produces because of load when drive operation like this can pass through travel switch simultaneously, the contact of travel switch inside disconnect and closed time will produce electric spark because of larger electric current, be easy to the damage causing travel switch, thus cause drive corruption.
Utility model content
The utility model provides that a kind of structure is simple, cost is low, Stroke Control precision is high, the adjustable smart linear driver with stroke control function of stroke.
For solving the problem, as an aspect of the present utility model, provide a kind of smart linear driver with stroke control function, comprise: control circuit board, be arranged on casing, control circuit board is provided with control chip, Hall interface, initial position detection switch interface, motor port, manual switch interface and power interface, control chip is connected with Hall interface, initial position detection switch interface, motor port, manual switch interface and power interface respectively; Motor, be arranged on casing, motor is connected with motor port; Push rod portion, is connected with motor by screw mandrel, and screw mandrel drives push rod portion stretching motion; Initial position detection switch, is connected with control chip by initial position detection switch interface; Hall element, is connected with control chip by Hall interface, and Hall element is arranged on motor, for generating revolution lap signal; Control chip controls the stroke in push rod portion according to revolution lap signal.
Preferably, screw mandrel is connected with push rod portion by bell of living.
Preferably, smart linear driver also comprises: worm screw, is arranged on the output shaft of motor; Worm gear, with screw mandrel, and worm gear and worm engaging.
The mode that the utility model is controlled by control chip controls stroke dimension, the precision of stroke dimension is high on the one hand, eliminate travel switch on the other hand, eliminate the risk that travel switch damages, and initial position detection switch is only for providing position signalling for control chip, atomic weak by the electric current of initial position detection switch, there is not the risk of damage, thus effectively ensure the stable performance of driver.
