Description
Technical field
The technology belongs to locking device field, and in particular to a kind of two-way memory alloy locking device.
Background technology
Rotary motion with fixed shafting is one of main forms of motion in machine driving.In Inertial Navigation Testing Device, search
The fields such as rope tracking table, the revolution of shafting is most important forms of motion.Often to realize high-precision requirement, this two kind equipment
Usually using straight drive torque motor as driving, the motor is in the case of not powered state to be freely rotated, but in this two class
Mechanical equipment is during debugging and transport etc., it is sometimes desirable to brake rotary axis.To realize the braking mesh of the equipment
, braking model common at present has the forms such as mechanical pin, electromagnetic brake.The brake apparatus of mechanical pin form, it is most
In the case of need artificially to go to plug, also have the bolt of electromagnetic drive, realize that the locking of bolt and disengagement act by automatically controlled.Electricity
Magnetic brake is using electromagnet principle, the braking of rotary axis system and disengagement is controlled to act by DC power supply.
Both the locking mechanism of bolt and electromagnetic brake has certain structure size and larger installation space will
It asks.For the smaller miniature turntable of design size, both locking modes tend not to meet that the limitation of its size is harsh, peace
The demand braked in the case of dress space is smaller.Therefore current braking technology can not often meet the braking need of tracking table
It asks.In addition electromagnetic brake power consumption is larger, if heat dissipation design is not perfect, easily causes the temperature of brake and its brake axle system of institute
It rises, so as to influence the installation accuracy of shafting.
Invention content
It is an object of the invention to：A kind of two-way memory alloy locking device is provided, solve to structure size require it is harsh,
The small rotary axis system of installation space can not lean on the problem of existing method auto lock and unlock, while can also reduce power consumption, drop
Wen Sheng near low arrestment mechanism.
Technical scheme is as follows：A kind of two-way memory alloy locking device including brake apparatus installing plate, is being made
Installation unlock guide wheel, two-way memory alloy silk on dynamic device installing plate, one end of two-way memory alloy silk is fixed on brake apparatus
On installing plate, around brake apparatus installation plate surface one enclose, and be wound on unlock guide wheel on after, the other end with unlock voussoir connect；
In the center opening of brake apparatus installing plate, and rotating shaft is made to pass through the hole, the left and right sides of rotating shaft passes through micro- engagement respectively
It is secondary to be contacted with left brake shoe with right brake shoe, and left brake shoe connect braking leaf spring with the downside of right brake shoe, upside then clamps
Unlock voussoir.
The brake apparatus installing plate is mounted on fixed pedestal.
The two-way memory alloy silk is fixed on installation plate surface by wire drawing guiding pair.
The remarkable result of the present invention is：It is tight that the present invention is more applicable for structure size requirement compared with prior art
The locking braking occasion of the miniature rotary shafting severe, installation space is small.The arrestment mechanism can fully use the circumferential ruler of shafting
It is very little, while the demand of shaft axial dimension is reduced as far as possible.It can be in ms using the two-way memory alloy brake apparatus
The disengagement action of shaft is just realized in the grade time.It solves existing braking method and is not used to miniature rotary shafting auto lock
With the problem of disengagement.
Description of the drawings
Fig. 1 is a kind of two-way memory alloy locking device schematic diagram of the present invention
Fig. 2 is a kind of two-way memory alloy locking device side view of the present invention
In figure：1 unlock guide wheel, 2 two-way memory alloy silks, 3 wire drawing guiding pairs, 4, left brake shoe, 5 rotating shafts, 6 brake plates
Spring, 7 right brake shoes, 8 micro- Meshing Pairs, 9 unlock voussoirs, 10 brake apparatus installing plates, 11 fixed pedestals
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is described in further detail the present invention.
A kind of two-way memory alloy locking device, including brake apparatus installing plate 10, brake apparatus installing plate 10 is mounted on
On fixed pedestal 11, installation unlock guide wheel 1, two-way memory alloy silk 2, two-way memory alloy silk on brake apparatus installing plate 10
2 one end is fixed on brake apparatus installing plate 10,10 surface of installing plate is fixed on by 3, around 10 table of brake apparatus installing plate
Face one is enclosed, and be wound on unlock guide wheel 1 on after, the other end with unlock voussoir 9 connect；It is opened at the center of brake apparatus installing plate 10
Hole, and rotating shaft 5 is made to pass through the hole, the left and right sides of rotating shaft 5 passes through micro- Meshing Pair 8 and left brake shoe 4 and right braking respectively
Boots 7 contact, and left brake shoe 4 connect braking leaf spring 6 with the downside of right brake shoe 7, and upside then clamps unlock voussoir 9；
To rotary axis system is made to release braking, then 24V is energized to 2 both ends of two-way memory alloy silk, ms grades after energization
In time, two-way memory alloy silk 2 is i.e. collapsible, while unlock voussoir 9 is affected to move upwards, and so as to strut braking leaf spring 6, makes
Left brake shoe 4, right brake shoe 7 and rotating shaft 5 are separated from, and micro- Meshing Pair 8 does not work, and freedom can be realized in such rotating shaft 5
Rotation.In entire galvanization, two-way memory alloy silk 2 is in contraction state, and shafting is also accordingly in releasing braking shape
State reduces the voltage at 2 both ends of two-way memory alloy silk to 10V at this time, and two-way memory alloy is maintained at contraction state, but power consumption is shown
It writes and reduces, so as to fulfill the releasing braking function under small-power state.Want to realize braking, then disconnect to two-way memory alloy silk
2 power supply, then two-way memory alloy silk 2 restore within the time of several seconds or so to the original length, unlock voussoir 9 is in brake plate
It is moved downward under the action of 6 clamping force of spring, braking leaf spring 6 drives left brake shoe 4 and right brake shoe 7, is generated by micro- Meshing Pair 8
Frictional force restore to the holding state of rotating shaft 5.Shafting realizes braking again.
