Description
Technical field
The present invention relates to a kind of electromagnetic self-locking device, for micro motor transmission mechanism self-locking, more particularly to straight line electric
Push rod self-locking.
Background technology
General push rod or other linear actuators are mainly made up of motor, reduction box, drive lead screw etc. at present, motor via
Reduction box slows down and increases square effect, rotary torsion is sent into worm drive screw mandrel or worm screw, so as to drive actuator to work.And one
As drive the actuator of relatively large load to have self-locking requirement safe and reliable with assurance mechanism, to general actuator, passed by spiral more
The self-locking in itself of system and motor is moved to provide the self-locking of actuating mechanism.Heavy load or screw-drive mechanism have large pitch or
This kind of self-locking and unreliable during large helix angle, does not reach security performance requirement.
Common linear actuator, such as electric pushrod are driven using motor, can be used for the industries such as household, automobile, medical treatment.
Opened a window using electric pushrod when opening the door, promoted by piston rod and be supported by opening of doors and windows or closure, can obtain can to ensure door and window
By support, push rod self-locking is claimed.For the electric pushrod without self-locking mechanism, provided certainly by mechanism's friction in itself
Lock, and when mechanism friction is not enough, especially with the high speed push rod of large pitch worm drive part, mechanism cannot then provide enough
Self-lock force ensure supporting reliability.Therefore a kind of self-locking device urgently is designed to existing line handspike, is met to push rod self-locking
Requirement.
The content of the invention
It is used for micro motor self-locking and linear actuator or electric pushrod the invention provides a kind of electromagnetic self-locking mechanism
Self-locking.A kind of line handspike electromagnetic self-locking device of present invention design, including frictional disk, metal brake disk, suction magnet, compression bullet
Spring, fixed seat, it is characterised in that：Suction magnet, holddown spring, metal brake disk, frictional disk are set with according to this in fixed seat, are rubbed
Wipe disk to be connected with the rear shaft of motor, connection reduction box in motor front end has projection in the both sides of the edge of brake disc, and projection is embedded in
In sliding groove on the medial surface of fixed seat.Self-locking device of the invention can be by synchronous with motor that self-lock force is realized in electric, power-off
Removal and applying so that drive system power-off do not work when be obtained in that self-locking device provide additional friction torque, reach
Reliable self-locking, in energization work, self-locking device sheds self-lock force, ensures drive system normal work.Self-locking device is by by frictional force
Square is acted on motor shaft, and is amplified via reduction box, and drive mechanism can be made to obtain the self-locking torque of times several levels, and self-locking property can
Lean on；The self-locking device unloading in drive system normal work simultaneously, will not produce harmful effect to drive system.The electromagnetic self-locking device
Simple structure, small volume is highly suitable for micro motor drive system, is particularly suited for conventional linear actuator such as electric pushrod
Deng.
The present invention is elaborated with reference to the accompanying drawings and examples.
Brief description of the drawings
Fig. 1 is that self-locking device of the invention is mounted in motor afterbody assembling structure schematic diagram.
Fig. 2 is self-locking device entirety profile of the invention.
Fig. 3 is self-locking device fixed seat profile of the invention.
Specific embodiment
A kind of electromagnetic self-locking device in figure, it mainly includes：Fixed seat 3, suction magnet 4, holddown spring 5, metal brake disk
6th, frictional disk 7.As shown in figure 1, wherein self-locking device is arranged in fixed seat 3, fixed seat 3 is sleeved on the afterbody of motor 2, such as Fig. 2,
A frictional disk 7 is fixedly mounted on shaft after motor 2, frictional disk can be with motor synchronous axial system；Lived in rear shaft extension
Dynamic that brake disc 6 is housed, brake disc can slide and rotate on outrigger shaft；Suction magnet 4 is arranged in fixed seat 3 away from motor
Position, is equipped with holddown spring 5 between disk magnet 4 and metal brake disk 6, and spring top clamping brake disc 6 makes itself and frictional disk 7 tight
It is close to close.There are two projections in the both sides of edges of metal brake disk 6, coordinate with the interior sliding groove 8 opened of fixed seat 3, as shown in figure 3, by
The rotation of this limitation fixed seat 3, circumferentially rotates it and is limited.
When motor and self-locking device are powered off, actuating mechanism does not work, and has self-locking requirement.As shown in Fig. 2 now suction magnet
4 dead electricity, it is impossible to produce magnetic force, holddown spring 5 that metal brake disk 6 is tightly pressed together with frictional disk 7, normal pressure between the two
Produce friction, when actuating mechanism rub in itself provided self-locking moment be not enough to overcome external applied load when, brake disc produce rub
Wipe torque and increase square via motor shaft to reduction box 1, and act on power transmission shaft（Screw mandrel or worm screw）On, overcome external applied load to reach self-locking
Purpose.
When motor and self-locking device are powered, actuating mechanism work, without self-locking requirement.Now suction magnet energization adhesive, makes
Metal brake disk 6 overcomes the elastic force that holddown spring 5 is produced under electromagnetic force, departs from frictional disk on motor shaft 7, sheds and rubs
Wipe power, it is ensured that actuator normal operation work.
Beneficial effects of the present invention：Self-locking device of the invention can be by synchronous with motor that self-lock force is realized in electric, power-off
Removal and applying so that drive system is obtained in that the additional friction torque that self-locking device is provided when power-off does not work, and reaching can
By self-locking, in energization work, self-locking device sheds self-lock force, ensures drive system normal work.Self-locking device is by by moment of friction
Act on motor shaft, and amplify via reduction box, drive mechanism can be made to obtain the self-locking torque of times several levels, self-locking property can
Lean on；The self-locking device unloading in drive system normal work simultaneously, will not produce harmful effect to drive system.The electromagnetic self-locking device
Simple structure, small volume is highly suitable for micro motor drive system, is particularly suited for conventional linear actuator such as electric pushrod
Deng.
