Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, 2 and 4, a braking device for a linear motor includes: the rotor 1, the armature 3, the elastic component, the electromagnet 7 and the rack 8.
The rack 8 is fixedly arranged on the linear motor, and the rotor 1 moves on the linear motor;
specifically, the armature 3 is movably mounted on the mover 1, and the armature 3 is made of ferromagnetic metal; the armature 3 is in a sawtooth shape and is matched with the rack 8;
the elastic part is arranged in the rotor 1 and is connected with the armature 3;
the electromagnet 7 is fixedly arranged in the rotor 1, and a power line 2 is arranged on the electromagnet;
more specifically, in the present embodiment, the power line 2 is used for conducting current with the outside, the power line 2 is used for conducting current with the electromagnet 7, and when the electromagnet 7 is powered on, an electromagnet is generated to magnetically attract the armature 3.
In the present embodiment, the material of the armature 3 is ferromagnetic metal (the ferromagnetic metal in the present embodiment is defined as a metal material capable of attracting a magnet, and common ferromagnetic metals are simple iron, cobalt, nickel, and alloys thereof). The armature 3 is made of ferromagnetic metal so that when the electromagnet is energized, the generated electromagnet can attract the magnet. Therefore, it is a necessary technical condition that the armature 3 is a ferromagnetic metal. More specifically, the ferromagnetic metal used in this embodiment is iron.
In this embodiment, the armature 3 is serrated and cooperates with the rack 8. The rack 8 is fixed relative to the linear motor, the rack 8 is matched with the armature 3 and presents the same saw teeth, and the depth and the distance of the saw teeth are the same.
In this embodiment, the elastic member is a spring 6. It should be noted that the spring 6 in this embodiment is made of a non-ferromagnetic metal (the definition of the non-ferromagnetic metal in this embodiment corresponds to the definition of the ferromagnetic metal in this embodiment, i.e., there is no material capable of attracting the magnet).
The non-ferromagnetic metal is selected as the material of the spring 6, so that the influence on the elasticity of the spring 6 when the electromagnetism is electrified is avoided, and the influence on the braking time is further avoided.
It should be noted that it is not a necessary technical requirement that the spring 6 in the present embodiment is made of a non-ferromagnetic metal. The use of ferromagnetic metal for the spring 6 also allows to have a very small gap effect.
Therefore, even if the spring 6 uses a ferromagnetic metal, it will fall within the present embodiment
In this embodiment, two ends of the mover 1 are provided with connecting holes 4, the armature 3 is fixedly provided with fixing bolts 5, and the fixing bolts 5 penetrate through the connecting holes 4 to be connected with the armature 3.
Specifically, the fixing bolt 5 in this embodiment is designed in a T shape, and has a limiting effect.
Referring to fig. 3, a circle of limiting ring is arranged in the connecting hole 4, one end of the fixing bolt 5 with a smaller diameter on the outer wall is fixedly connected with the armature 3, when the electromagnet 7 is powered off, the armature 3 is far away from the rotor 1 under the elastic force of the spring 6, and at the moment, one end of the fixing bolt 5 far away from the armature 3 can be abutted against the connecting hole 4, so that the armature 3 and the rotor 1 are prevented from falling off due to the elastic force.
The working principle of the embodiment is as follows:
when the device moves up and down along with the moving device, the electromagnet 7 is in an energized state.
When the electromagnet 7 is electrified, the electromagnet 7 generates magnetism and attracts the armature 3, so that the armature 3 is attached to the electromagnet 7. The spring 6 is now compressed.
When the device needs braking, the electromagnet 7 is in a power-off state.
When the electromagnet 7 is powered off, the electromagnet 7 does not produce magnetism to attract the armature 3 any more, at the moment, due to the elastic force of the spring 6, the spring 6 can be stretched, the armature 3 is driven to move towards the direction far away from the rotor 1 (namely, close to the rack 8), and due to the fact that the armature 3 and the rack 8 are both provided with the same saw teeth, the armature 3 is meshed with the rack 8, and braking is carried out.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
