End is compressed with iron core, and the other end and drive end bearing bracket compress, and spring is located in rear end cap cavity, and one end is pushed down inside rear end cap, another
End resists latch bracket, and latch bracket leads to pull rod to be threadedly coupled, and pull rod and armature interference fit connect, and pull rod passes through in drive end bearing bracket
Hole, drive end bearing bracket are connect with shell, and drive end bearing bracket inner face pushes down the coil block other end.When no power, acted in pre-pressure of the spring
Under, it is compressed inside the step of pull rod and drive end bearing bracket, when energization, under electromagnetic action, armature is bonded with iron core, armature drive pull rod
It is mobile, to play draw.
The characteristics of dynamic iron core is: pull rod, armature and latch bracket form dynamic iron core, and wherein pull rod and armature are matched for interference
It closes, pull-rod spring support is to be threadedly coupled.
The characteristics of static iron core is: rear end cap and iron core are connected through a screw thread composition static iron core.
The assembling and setting step of the towed electromagnetic actuator is: step 1 is that pull rod and armature are first carried out interference
Cooperation assembly, step 2 are that pull rod screw one end is passed through to iron core mesoporous, and step 3 is that latch bracket is connected through a screw thread assembly
Onto pull rod, step 4 is by the component of step 1 to three assembly loaded on inside shell cavity, and step 5 is by iron core and shell
It is connected by screw to, step 6 is that coil block is placed in inside shell cavity, and core interior plane, coil are pushed down in an end face
Component inner cavity and iron core outer circle cooperate, and step 7 is that the mesoporous of drive end bearing bracket is passed through pull rod, and inner face pushes down the another of coil block
One end face, step 8 are that drive end bearing bracket is connect by screw with shell, and step 9 is to place the spring in rear end cap cavity, one end
With latch bracket compression, the other end and rear end cap inside are compressed, and step 10 connect for rear end cap is passed through screw thread with iron core, in addition,
The precompression of spring can be adjusted by adjusting the position of rear end cap.
Beneficial effects of the present invention: (1) dynamic iron core and static iron core are all fabricated structure, convenient for assembly, debugging, precompression
It is adjustable.(2) there is bigger electromagnetic traction power under equal volume, environmental suitability is strong, high reliablity.
Detailed description of the invention
