Description
Technical field
The present invention relates to electromagnetism putting technique field, particularly a kind of permanent-magnet linear push rod.
Background technology
Push rod is a kind of drive device of straight reciprocating motion.Available in various simple or complicated technological process as
Executing agency uses, to realize far distance controlled, centralized Control or automatically control.
Traditional putter action is slow, and mechanism structure design is complicated, and it is usually to be combined by motor and leading screw.Its body
Product is larger, and stroke is limited.
The content of the invention
Based on this, in view of the above-mentioned problems, being necessary to propose a kind of permanent-magnet linear push rod, the permanent-magnet linear push rod can be realized
Big stroke range motion, and be swift in motion, high-frequency reciprocating motion can be achieved, can be realized using permanent magnetism push rod and permanent magnet drive non-
Often flexible application.
The technical scheme is that：A kind of permanent-magnet linear push rod, including cylinder barrel and the magnet coil group outside cylinder barrel；
The cylinder barrel is made up of nonferromagnetic material, and permanent magnetism push rod is provided with the cylinder barrel, and the diameter of the permanent magnetism push rod is less than cylinder barrel
Diameter.
As shown in figure 3, the magnet coil being powered can produce magnetic field, as shown in figure 4, the magnetic field that the magnet coil being powered is produced
It is relevant with its sense of current, electromagnetism push rod can be promoted using the above-mentioned characteristic of magnet coil, changes the electric current in magnet coil
Direction can change the direction of motion of electromagnetism push rod.
Preferably, the two ends of the cylinder barrel are provided with linear bearing, and the linear bearing is sheathed on permanent magnetism push rod, described straight
Bobbin is held, permanent magnetism push rod and cylinder barrel it is concentric set.
Permanent magnetism push rod is supported using linear bearing, permanent magnetism rod diameter is less than the diameter of cylinder barrel, it is to avoid push rod and cylinder barrel
Contact, reduces frictional resistance.
Preferably, the permanent magnetism push rod is made up of nonferromagnetic material, on the permanent magnetism push rod in be embedded with multiple permanent magnetism strong
Magnet, axle center of the multiple permanent magnetic strong magnetic iron along the permanent magnetism push rod is set, and in the multiple permanent magnetic strong magnetic iron adjacent two forever
Magnetic strength magnet tool is at regular intervals.
It is small using driving current in permanent magnetic strong magnetic iron insertion permanent magnetism push rod, can be achieved, it is swift in motion, the effect of pushing torque greatly
Really.
Preferably, the magnet coil group is driven by permanent magnet drive.
Permanent magnet drive can control the working condition of the different magnet coils of horizontal alignment in coil group, different by switching
Magnet coil work make permanent magnetism push rod movement under force in cylinder barrel, while by the size of electric current in control coil with controling power
The size of square.
The beneficial effects of the invention are as follows：
1st, it is simple in construction, it is easy to use, innovatively it is embedded in using permanent-magnet material in rod member and makees push rod, required driving current
It is small, it is swift in motion, pushing torque is big；
2nd, the permanent magnetism push rod of rod member is embedded in by multiple permanent magnetic strong magnetic iron, can be formed and walked step by step when magnetic field promotes push rod
Enter formula promotion, not only pushing torque is big, and stroke is long.
