Abstract
A kind of electric cylinders of embedded magnetic seal apparatus, including motor, shaft coupling, screw mandrel, nut, line slideway, slide unit, outer cover, magnetic seal apparatus；Described motor is connected by described shaft coupling with described screw mandrel, described screw mandrel is through in the middle part of described nut, nut overcoat has described slide unit, slide unit is slidably connected by sliding block and described line slideway, described outer cover is located at the outermost of device, groove is provided with, described magnetic seal apparatus is provided with groove；Motor drives screw mandrel motion using shaft coupling, the rotary motion of motor is converted into moving along a straight line by screw mandrel, and slide unit is slided by sliding block on line slideway, and screw mandrel is by nut preferably transmitting thrust, leak is sealed present in magnetic seal apparatus supplement outer cover, realizes being fully sealed for electric cylinders.The beneficial effects of the utility model are：Electric cylinders carry out magnetic envelope in the groove of outer cover with magnet, avoid sealing device and friction occurs with electric cylinders part and improves the external aesthetics of electric cylinders.
Description
Technical field
It the utility model is related to a kind of electric cylinders, more particularly to a kind of electric cylinders of embedded magnetic seal apparatus.
Background technology
Electric cylinders are the modular products by servomotor and leading screw integrated design, and the rotary motion of servomotor is changed
Be in line motion, at the same precise rotation is controlled, accurate revolution control and accurate torque control be transformed into precise speed control,
Accurate Position Control and the control of accurate thrust, it is the brand-new revolutionary product for realizing high accuracy linear motion series.
But it is not perfect enough for the sealing on straight line module at present, existing generally use soft magnetic stripe is sealed
Or blow-by, but often because steel band is relatively thin, internally during element high-speed cruising, soft magnetic stripe is easily scratched, and can not be realized
Sealing.
Therefore, for disadvantages described above, it is necessary to effectively be innovated to prior art.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of electric cylinders of embedded magnetic seal apparatus, this kind
Electric cylinders carry out magnetic envelope on the inside of outer cover using strong magnet, on the one hand avoid sealing device and are rubbed with electric cylinders part, extend
The service life and sealing property of sealing device, on the other hand, the magnet are embedded in inside outer cover, improve the outer of electric cylinders
In aesthetics.
To achieve the above object, the utility model provides following technical scheme：
A kind of electric cylinders of embedded magnetic seal apparatus, including motor, shaft coupling, screw mandrel, nut, line slideway, slide unit, outer cover,
Magnetic seal apparatus；Described motor is connected by described shaft coupling with described screw mandrel, and described screw mandrel is through described spiral shell
Female middle part, nut overcoat have described slide unit, and slide unit is slidably connected by sliding block and described line slideway, described outer cover position
In the outermost of device, groove is provided with, described magnetic seal apparatus is provided with groove；Motor drives silk using shaft coupling
Bar is moved, and the rotary motion of motor is converted into moving along a straight line by screw mandrel, and slide unit is slided by sliding block on line slideway, and screw mandrel is borrowed
Nut preferably transmitting thrust is helped, leak is sealed present in magnetic seal apparatus supplement outer cover, realizes being fully sealed for electric cylinders.
The beneficial effects of the utility model are：
This kind of electric cylinders carry out magnetic envelope in the groove of outer cover using magnet, on the one hand avoid sealing device and electric cylinders part
Rub, extend the service life and sealing property of sealing device, on the other hand, the magnet is embedded in inside outer cover,
Improve the external aesthetics of electric cylinders.
