On stroke nut, be sheathed on screw mandrel outer and stroke push rod that linked with stroke nut and the overcoat that is sheathed on outside stroke nut
Pipe, electric motor assembly includes motor and the train of reduction gears with motor linkage.
In use, motor is implemented to drive to train of reduction gears, and train of reduction gears can then be implemented to drive to screw mandrel, promote
It is in screw mandrel and forms rotation in push rod, now stroke nut is spacing by the circumference of outer tube, promotes stroke nut not locate
In being rotated on screw mandrel, it can be only on screw mandrel and moved back and forth by the rotation of screw mandrel, stroke nut can then drive stroke when moving
Putter action.
Stroke push rod in such Linear motor-driven push rod has three phases, i.e., maximum advanced position, on screw mandrel
Persistent movement state and maximum projecting position.In order that stroke push rod can promote in maximum advanced position and maximum projecting position
Motor stopping, it will usually implement to set to motor, so that its stroke is accurately controlled and protected to whole implementation, so
And, motor is after prolonged use, and more or less change can occur for its predetermined value, causes the control accuracy of stroke to occur
Deviation.
The content of the invention
In view of the shortcomings of the prior art, the utility model provide a kind of Stroke Control it is accurate, simple in construction, control
The stable Linear motor-driven push rod with stroke limit protection device.
To achieve the above object, the utility model provides following technical scheme：One kind carries stroke limit protection device
Linear motor-driven push rod, include electric motor assembly, the screw mandrel linked with electric motor assembly, the stroke spiral shell that is sheathed on screw mandrel

Electrical connection, described retract stroke controlling switch is provided with towards one end of stroke nut and can touch the collision piece closed with stroke nut,
The extension stroke controlling switch actuator linked with stroke nut is provided with outer tube.
Using above-mentioned technical proposal, opened by setting the retract stroke control of stroke push rod between motor and stroke nut
Close and extension stroke controlling switch, and set the extension stroke controlling switch linked with stroke nut to drive in outer tube
Part.In use, when motor is started working, and screw mandrel implements rotation, stroke nut thereon drives stroke push rod to implement
Stretch, when stroke push rod extends to maximum position, the extension stroke controlling switch actuator linked with stroke nut is to stretching
Travel control switch is implemented to touch, and promotes motor to be stopped.When stroke push rod bounces back, when bouncing back to maximum position, stroke
Nut can be implemented to touch with the collision piece of retract stroke controlling switch, promote motor stopping.So set not only to stroke push rod
Stroke Control precisely, and control it is more stable, structure is more simple.
The utility model is further arranged to：Extension stroke controlling switch actuator, which includes, to be fixedly arranged on stroke nut simultaneously
The drive rod being be arranged in parallel in screw mandrel, axial one end of drive rod is extended at extension stroke controlling switch, and extension stroke control
System switch is provided with the conflict piece that can be contradicted with drive rod.
Using above-mentioned technical proposal, drive rod is moved with the movement of stroke nut, is so set and is not only simple in structure, and
And convenient disassembly.
The utility model is further set to：It is provided between motor and stroke nut at support frame, support frame and is provided with line
Road plate, described retract stroke controlling switch and extension stroke controlling switch is fixedly arranged on the wiring board respectively.
Using above-mentioned technical proposal, such setting structure is compact and reasonable.
The utility model is further described below in conjunction with the accompanying drawings.
