Formula brake.Contact brake is about utilizing friction between rotating member and static element, and whens frictional force brakes is more common
Brake type.In the prior art, it for this contact brake, needs to utilize biggish space, while friction system
The disturbance factor being subject to is relatively more.
Utility model content
The purpose of this utility model is to provide a kind of brakes for joint of mechanical arm, close for solving to mechanical arm
The technical issues of section is braked.
The technical solution adopted by the utility model to solve its technical problems is that:
A kind of brake for joint of mechanical arm, including braked wheel, spring, brake bar and braking drive organ, braking
Driving mechanism uses electromagnet drive mechanism；
The circumferential direction of braked wheel is equipped with multiple detent recess, and the front end of the brake bar is corresponding with the detent recess to be set
It sets, the rear end of brake bar and the power output end of electromagnet drive mechanism are correspondingly arranged；Tripping spring is sleeved on the brake bar
Outside.
Further, the front end of the brake bar uses tip.
Further, the electromagnet drive mechanism includes braking driving chamber and braking soft magnet, and the rear end of brake bar can
Flexible is located in braking driving chamber；
Braking soft magnet is mounted in braking driving chamber, and outside is wound with braking excitation coil, and braking excitation coil is logical
It crosses switch and conducting wire connects to power supply；The rear end of braking soft magnet and the brake bar is correspondingly arranged.
Further, the front end of the braking driving chamber is equipped with the braking directed cavity with its internal run-through, brakes directed cavity
Two sides be equipped with braking sliding slot；The rear end sides of the brake bar are equipped with braking sliding rail, and braking sliding rail is slidably mounted on system
In dynamic sliding slot.
Further, driving plate is braked in the rear end of the brake bar.
The effect provided in utility model content is only the effect of embodiment, rather than whole effects that utility model is all
Fruit, have the following advantages that in above-mentioned technical proposal or the utility model has the advantages that
The technical solution designed in the utility model can be easy to implement the braking of mechanical arm.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model embodiment；
Fig. 2 is the schematic diagram of the section structure of braking drive organ in the utility model embodiment；
In figure: 1, braked wheel；2, spring；3, brake bar；4, braking drive organ；11, detent recess；41, braking driving
Chamber；42, soft magnet is braked；43, directed cavity is braked；44, driving plate is braked.
Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this
Utility model is described in detail.It should be noted that illustrated component is not drawn necessarily to scale in the accompanying drawings.The utility model
It is omitted to known assemblies and well-known technique description, to avoid the utility model is unnecessarily limiting.
As illustrated in fig. 1 and 2, a kind of brake for joint of mechanical arm, including braked wheel 1, spring 2, brake bar 3 and system
Dynamic driving mechanism 4.Braked wheel 1 is connect with the machine shaft that mechanical joint operates, and it is recessed that the circumferential direction of braked wheel 1 is equipped with multiple brakings
Slot 11.The brake bar 3 is for braking braked wheel 1, and the front end of brake bar 3 uses tip, with the detent recess 11
It is correspondingly arranged；The rear end of brake bar 3 and the power output end of braking drive organ 4 are correspondingly arranged.Tripping spring 2 is sleeved on described
3 outside of brake bar, when not needing braking, by reset force for driving brake bar 3 to extract from braked wheel 1.
Braking drive organ 4, can be used electromagnet drive mechanism, it includes braking driving chamber 41 and braking soft magnet 42,
Braking soft magnet 42 is mounted on the rear end in braking driving chamber 41, and outside is wound with braking excitation coil, brakes excitation coil
It is connected to power supply by switch and conducting wire.The front end of the braking driving chamber 41 is equipped with the braking directed cavity with its internal run-through
43, the two sides of braking directed cavity 43 are equipped with braking sliding slot.What the rear end of the brake bar 3 inside and outside can move is mounted on braking guiding
In chamber 43；The settable braking driving plate 44 in the rear end of brake bar 3, the two sides of brake bar 3 are equipped with braking sliding rail, and braking sliding rail can be slided
Dynamic is mounted in braking sliding slot.The rear end braking driving plate 44 of the brake bar 3 uses magnetically attractive material (such as ferrous material), with
The braking soft magnet 42 is correspondingly arranged.The rear end of the tripping spring 2 is connect with the outer end of braking directed cavity 43, tripping spring
2 front end is connect with the brake bar 3.
In application process, when energized, braking drive organ 4 adsorbs brake bar 3 (tripping spring 2 is compressed) backward,
Detent recess 11 on brake bar 3 and braking device wheel is detached from.Mechanical arm works well.When power is off, brake bar 3 loses braking and drives
The suction-operated of motivation structure 4 backward；Brake bar 3 puts in forward in detent recess 11, reaches under the effect of 2 reset force of tripping spring
To braking effect.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
It is above-mentioned although specific embodiments of the present invention are described with reference to the accompanying drawings, but it is not practical new to this
The limitation of type protection scope, on the basis of technical solutions of the utility model, those skilled in the art do not need to pay creativeness
The various modifications or changes that can make of labour it is still within the protection scope of the present utility model.
