Description
Technical field
The present invention relates to the field such as high-grade, digitally controlled machine tools, production line, more particularly, it relates to a kind of brake.
Background technology
Chinese patent CN201320596839.7 brake device of linear motor, relates to a kind of linear electric motors band-type brake dress
Putting, its innovative point is: described band brake apparatus is integrally attached on linear electric motors housing, it include one be sleeved on linear electric motors move
Sub-axle is outer and inner ring arranges the annular static iron core of coil, dynamic iron core be arranged on static iron core inner ring and linear motor rotor axle it
Between；Some and dynamic iron core quantity is arranged on static iron core to the back-moving spring mated, described back-moving spring.
Problematically, owing to using spring structure, braking time is long, and Mechanical Reliability is low, it is impossible to straight line locking.
Summary of the invention
The present invention provides a kind of convenience, applicable brake.
In order to achieve the above object, one linear electric motors permanent magnet brake of the present invention, including static iron core assembly and dynamic plate group
Part, described static iron core assembly comprises the many groups coil being embedded in static iron core；The top of each group of coil arranges yoke and magnet steel；Institute
State board component to include being determined plate and dynamic plate by what spring leaf was spaced；Described dynamic plate is placed in above described yoke and magnet steel.
Wherein, described static iron core assembly is fixed with linear electric motors secondary, and described dynamic board component is fixed with linear electric motor primary.
The present invention has the beneficial effects that:
1. straight line band-type brake, volume is little, lightweight.
2. processing is simple, and installation and maintenance are easy.
3. coupling reliable, braking flexibly, can realize automatically controlling operating mechanism and remote-controlled operation, ultrashort braking
Time.
4. controlling power little, service life is long.
5. stable performance, safe and reliable.
The most simple and compact for structure, easy and simple to handle, accurately combination can be ensured within the extremely short time.
7., by regulating winding and magnet steel characteristic, can diversification be applied in combination.
8. linear electromagnetic brake is completely without motion, in addition to electric magnet, uses the brake of permanent magnet to need not electric power,
Space and efficiency can be saved.

Detailed description of the invention
As illustrated in fig. 1 and 2, linear electric motors brake of the present invention is largely divided into two parts, and respectively static iron core assembly is with dynamic
Board component, static iron core assembly comprises coil 1, static iron core 2, yoke 4 and magnet steel 3；Dynamic board component comprises dynamic plate 5, determines plate 7 and spring
Sheet 6.Static iron core assembly is fixed with linear electric motors secondary, and dynamic board component is fixed with linear electric motor primary.After brake power-off, coil
Can not produce magnetic field, magnet steel field circuit moves plate by adhesive makes linear electric motor primary be indirectly connected with secondary, i.e. motor
It is in band-type brake state, it is impossible to operating.After brake powers on, coil generation magnetic field, coil magnetic field loop short circuit magnet steel field circuit,
Magnet steel field circuit can not pass through air gap, i.e. magnet steel field circuit adhesive can not move plate.And then determine plate by spring leaf, make plate
With static iron core components apart, motor is operated.
As it is shown on figure 3, coil blackout: after brake power-off, coil can not produce magnetic field, and magnet steel field circuit passes through adhesive
Dynamic plate makes linear electric motor primary be indirectly connected with secondary, i.e. motor is in band-type brake state, it is impossible to operating.Figure shows magnetic
Loop, field NS level.
As shown in Figure 4, coil powers on: after brake powers on, and coil produces magnetic field, coil magnetic field loop short circuit magnet steel magnetic field
Loop, magnet steel field circuit can not pass through air gap, i.e. magnet steel field circuit adhesive can not move plate.And then determine plate by spring leaf,
Making plate and static iron core components apart, namely linear electric motor primary separates with secondary, and motor is operated.Figure shows magnetic
Loop, field NS level.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto,
Any those familiar with the art in the technical scope of present disclosure, according to technical scheme and
Inventive concept equivalent or change in addition, all should contain within protection scope of the present invention.
