Description
Technical field
The utility model is related to a kind of electric lost brake, belongs to the manufacturing technology field of brake.
Background technology
Existing brake is mainly made up of brake bracket, brake component and manipulation device etc., by the control to manipulation device,
Brake component movement is set to produce frictional force, so as to realize braking.Existing brake produces friction by then passing through mechanical movement
Torque brake, the volume of brake bracket and brake component is big, and in braking procedure caloric value is larger.
Utility model content
The purpose of this utility model is to provide a kind of reasonable in design, small volume, and braking ability is good, the strong dead electricity of heat-sinking capability
Formula brake.
The technical solution of the utility model is：Electric lost brake, is included in the yoke of internal coil groove, the coil groove
If magnet exciting coil, the armature of yoke inner face is placed in, described yoke one end is connected with cover plate, is provided between the cover plate and armature
Connect the intermediate of drive block, the two ends of the intermediate are provided with friction piece, the yoke inner face provided with multiple spring bases and
Play and install bullet pin in key seat, the spring base in installing spring, the bullet key seat, bullet key seat is fixed in one end of the bullet pin.
The armature is provided with bullet pin-and-hole, screw hole.
The periphery of the yoke is provided with outer ring, is connected between yoke and outer ring with epoxy resin layer.
The cover plate is with yoke with screw through installation.
The cover plate, armature, one-to-one radiating positioning hole is circumferentially uniformly distributed in yoke.
The utility model sets multiple springs in yoke, ensure that balance of the armature under power failure state and effectively system
It is dynamic.With finger setting is played between armature and yoke, that is, ensure the accuracy of adhesive between armature and yoke, can guarantee that armature exists again
Flexible motion on axial direction.Circumferential uniform radiating positioning hole is set on yoke, armature, cover plate, that is, ensured when mounted
Accuracy, the temperature that can be kept relative stability again during brake.Epoxy resin layer is used between yoke and outer ring
It is connected, the periphery of yoke can be protected, is less subject to the influence of electromagnetism and environment temperature, it is ensured that stopping power.This practicality
It is new to be particularly suitable for use in Digit Control Machine Tool AC adjustable speed motor system and control position very strict occasion, in defense technology field
Task can be completed in harsh working environment.

Embodiment
Below by embodiment, and with reference to accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Fig. 1~Fig. 5, electric lost brake includes setting in the yoke 1 of internal coil groove 14, the coil groove 14
Magnet exciting coil 3, is placed in the armature 4 of the inner face of yoke 1, and described one end of yoke 1 is connected with cover plate 6, the cover plate 6 and armature 4 it
Between the intermediate 10 provided with connection drive block 7, the intermediate 10 uses irony, inwall and the close-fitting of drive block 7 of intermediate 10
Close, the two ends of the intermediate 10 are provided with friction piece 5, and the external diameter of friction piece 5 is identical with the external diameter of intermediate 10, the yoke 1
Inner face is provided with multiple spring bases 13 and plays installing spring 9 in key seat 15, the spring base 13, and the other end of spring 9 is connected to rank
Installing bullet pin 8 in iron 4, the bullet key seat 15, bullet key seat 15 is fixed in one end of the bullet pin 8.
The armature 4 is provided with bullet pin-and-hole 18, screw hole 17.
The periphery of the yoke 1 is provided with outer ring 2, is connected between yoke 1 and outer ring 2 with epoxy resin layer 11, to magnetic
The periphery of yoke 1 has protective effect.
The cover plate 6 is with yoke 1 with screw 12 through installation.
The cover plate 6, armature 4, one-to-one radiating positioning hole 16 is circumferentially uniformly distributed in yoke 1.
In use, when magnet exciting coil 3 it is electric when, armature 4 attracts to the direction of magnet exciting coil 3, and spring 9 compresses, friction piece 5 with
Space is produced between intermediate 10, the frictional force for acting on intermediate 10 is diminished, the drive block 7 being connected with intermediate 10 can be with
Rotate.When 3 dead electricity of magnet exciting coil, armature 4 is drawn close under the elastic force effect of spring 9 to friction piece 5, and intermediate 10 rubs at two pieces
Under the frictional force collective effect of rub body 5, drive block 7 is set to slow down until stopping operating.
It the foregoing is only the utility model preferably embodiment, but protection domain of the present utility model not office
It is limited to this, any one skilled in the art can readily occur in the technical scope that the utility model is disclosed
Change or replacement, should all cover within protection domain of the present utility model.
