Therefore long delay detection is the important indicator that circuit breaker manufactures.
The operation principle of chopper is, the Fig. 3 in conjunction with in Figure of description: when performance loop electricity
During stream overrate, thrermostatic bimetal-plate 1-1 is deformed after being heated, to passive layer one lateral bending
Song, until tripping screw nail 26 top on the thrermostatic bimetal-plate 1-2 after being fixed on temperature distortion is arrived
Electrical apparatus release 1-3 tripping, cut-off loop.In order to prevent tripping screw nail 26 from repeatedly working for a long time
During occur that position loosens, dropout nut 27 of typically screwing in its one end, prevent from loosening.
Therefore, must accurately regulate, when producing chopper, the dropout spiral shell being fixed on thrermostatic bimetal-plate 1-1
Nail 26 to correct position, it is to avoid early jump, the generation of phenomenon is jumped or do not jumped to evening, and spiral shell of threading off
Female 27 screw, it is to avoid tripping screw nail moves relative to the thrermostatic bimetal-plate 1-2 after temperature distortion.
Owing to thrermostatic bimetal-plate 1-1 occurs bending and deformation, tripping screw nail 26, dropout nut can be driven
27 move, and motion track is non-linear, as shown in the 1-4 in Fig. 4 in Figure of description.For
Do not interfere the deformation naturally of thrermostatic bimetal-plate 1-1, regulate tripping screw nail 26, screw socket nut
The when 27 it is necessary to locus of accurate tracking tripping screw nail 26, makes tripping screw nail 26, de-mouth
The axis of nut 27 adjusting means must be with tripping screw nail 26, the axis weight of de-mouth nut 27
Close, such as: when thrermostatic bimetal-plate is displaced to b position from a position, tripping screw nail can be driven
26, de-mouth nut 27 axis deflection angle θ1, the axis of screw-nut adjusting means is also wanted partially
Gyration θ1, and move in the horizontal direction △ x1, move axially △ y1；Work as thrermostatic bimetal-plate
It is displaced to c position from b position, tripping screw nail 26, dropout nut 27 axis can be driven to deflect
Angle △ θ=θ1-θ2, the axis of screw-nut adjusting means also wants deflection angle △ θ, and at water
Square to mobile △ x=△ x2-△x1, move axially △ y=△ y2-△y1, the most just will not do
Disturb thrermostatic bimetal-plate normal deformation so that chopper misoperation, cause long delay detection inaccurate.
At present, in the production of chopper, the screw-nut on thrermostatic bimetal-plate is adopted mostly
With regulating manually, randomness is relatively big, and efficiency is low, and difficult quality controls.If realizing certainly
Dynamic production, can avoid manually-operated randomness, thus ensure product quality, improves raw
Produce efficiency and automatization level.The core requirement being automatically adjusted tripping screw nail is can not be to dropout

Existing electric and pneumatic automatically screw screwdriver, one will produced by tight tip of screw
Constant-pressure could start, it is impossible to meets the no axial pressure regulation requirement of tripping screw nail nut.Just
For prior art, designer Zhang Feng proposes a kind of automatic winding device of tripping screw nail, can be real
Now take off the no axial pressure regulation of mouth screw, but screw can only be adjusted, it is impossible to regulation spiral shell
Mother, and due to its feed mechanism by the gear ratio that straight-tooth gear is secondary ensure to screw shaftless to
Pressure regulates, and gear pair gear ratio is fixed, and just can only regulate the screw of a kind of corresponding pitch, suitable
Answering property is relatively weak.Designer Teng Bing proposes a kind of screw-nut and is automatically adjusted winding device,
Achieve automatically screwing of tripping screw nail nut dexterously, but the leading screw spiral shell that its feed mechanism uses
Identical with screw pitch away from requiring, to ensure that the no axial pressure to tripping screw nail regulates, leading screw
Pitch once it is determined that, this device can only realize the automatic of the screw-nut identical with leading screw pitch.
But, the chopper of different manufacturers, the chopper of different model, tripping screw nail pitch phase not to the utmost
With, it is desirable to make the device of numerous specification, sometimes use the lead screw transmission of onesize pitch
Even not possible with, because the screw of not all specification can mate the silk that pitch is identical
Thick stick, even if pitch coupling, the most not necessarily meets transmission performance requirement.Designer Shao Xin sends out etc. and to carry
And one Shuan Rou axial adjustment mechanism with one heart, but do not provide the specific design scheme of mechanism, design
Person Xu Chao is automatically adjusted winding device to a kind of novel breaker and has carried out Frame Design, and develops
Chopper is automatically adjusted locking machine, but its not no axial pressure to screw-nut regulate into
Row design and elaboration.Designer's Li Xiuqin etc. proposes a kind of adjustment circuit breaker bimetal sheet automatically
The method of screw length, the method can only realize axial displacement, only adapt to passively by flexible joint
The pose of screw, inevitably applies active force to screw-nut, and this active force passes through
The interaction of screw, nut and thrermostatic bimetal-plate, and then thrermostatic bimetal-plate can be disturbed normally to become
Shape；And, its inside and outside sleeve can only rise simultaneously or decline simultaneously, therefore can only adjust simultaneously
Joint screw-nut is in axial orthokinetic same displacement, and in actual production, needs when regulation
Ensure that nut can be screwed to keep not after position is jumped on top at screw with axially-movable relative to screw
Dynamic, nut can continue to screw, until lock screw.
In sum, need to develop new tripping screw nail nut equipment.
