Abstract
The invention discloses an external force overload protector of a ship outfitting numerical control cutting machine, which is composed of a locating piece, a side plate, a binding post, a metal lead, a signal binding post, a baseplate, a metal fixed block, a metal dome and an alloy memory spring, wherein the locating piece is fixed above the baseplate; one end of the alloy memory spring is fixed on the locating piece; the cavity of the alloy memory spring is provided with the metal lead which is welded onto the binding post on the side plate; one side of the metal fixed block and one side of the metal dome are respectively provided with one signal binding post; a gap is arranged between the metal fixed block and the metal dome; and the other end of the alloy memory spring is fixed on the metal dome. When the numerical control cutting machine has barriers during walking and cutting, a motor stops rotating, operating current thereof instantly increases, metal leads connected in series on the motor quickly heat and raise temperature, two signal binding posts are communicated, motor power supply is cut off, then faults are quickly removed by workers, and the numerical control cutting machine restores to work, which is very convenient.
Description
Technical field
The present invention relates to a kind of novel external force overload protector of ship outfitting numerical control cutting machine, be mainly used in and prevent that motor overload from burning, belong to the ship machinery field.
Background technology
All there is a large amount of ship ' s equipment numerical control cutting machines in present a lot of large ship enterprise, is used for cutting hull plate is installed, and can enhance productivity greatly; But because factory's system complicacy is huge, numerical control cutting machine often runs into walking disorder when work, keeping off the walking guide rail not by timely discovery such as heavy steel plate; Thereby cause the track travel motor to run into back power overload; Thereby the accident with burn-down of electric motor has caused unnecessary loss, has also reduced production efficiency simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of external force overload protector of ship outfitting numerical control cutting machine.
What the present invention will solve is the deficiency that the obstacle burn-down of electric motor is met in the walking of spot ship fitting-out numerical control cutting machine.
For realizing the object of the invention, the technical scheme that the present invention adopts is:
The present invention is made up of locating piece, side plate, binding post, plain conductor, signal binding post, base plate, metal fixed block, metal clips and alloy memory spring; Locating piece is fixed on the top of base plate, and an end of alloy memory spring is fixed on the locating piece, in the cavity of alloy memory spring plain conductor is arranged; Binding post on plain conductor and the side plate is welded together; One side of metal fixed block and metal clips respectively is provided with a signal binding post, and metal fixed block and metal clips are fixed on the top of base plate, and the metal fixed block is positioned at the opposite of metal clips; Be provided with the gap between metal fixed block and the metal clips; The other end of alloy memory spring is fixed on the metal clips, and side plate is the part of base plate, is positioned at the sidepiece of base plate.
Wherein the gap between metal fixed block and the metal clips is 1mm-2mm; Plain conductor is flat serpentine and distributes in the cavity of alloy memory spring; The immediate set temperature of alloy memory spring is the 49-52 degree; The resistance of plain conductor is 50-60 ohm, and the alloy memory spring is the memory titanium alloy material.
Advantage of the present invention is: after the present invention installs, the binding post of external force overload protector of ship outfitting numerical control cutting machine is connected in the power supply circuits of numerical control cutting machine motor, and ground connection of signal binding post, another is connected on the urgent time-out pin of numerical control cutting machine internal control chip; When numerical control cutting machine walking cutting runs into obstacle, motor will stop operating, its operating current moment increase; Series connection plain conductor above that, rapid heating up is when temperature arrives about 50 degree; The alloy memory spring expands rapidly, and the metal fixed block bumped with metal clips moment is in the same place the conducting of two signal binding posts; Urgent time-out pin on the control chip is received ground signalling, and control chip breaks off the motor power supply rapidly, thereby the protection motor exempts to be burnt; The workman goes rapidly to fix a breakdown then, it's a few minutes wait to past plain conductor after temperature descend, the alloy memory spring shrinks; The signal binding post breaks off, and just resumes work, and is quite convenient.
This equipment of employing not only the life-span of numerical control device will promote greatly, more play the prevention and following huge effect, should have vast market prospect.

Specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further described.
Extremely shown in Figure 3 like Fig. 1; External force overload protector of ship outfitting numerical control cutting machine of the present invention is made up of locating piece 1, side plate 2, binding post 3, plain conductor 4, signal binding post 5, base plate 6, metal fixed block 7, metal clips 8 and alloy memory spring 9, and locating piece 1 is fixed on the top of base plate 6; One end of alloy memory spring 9 is fixed on the locating piece 1; Plain conductor 4 is arranged in the cavity of alloy memory spring 9, and plain conductor 4 is welded together with the binding post 3 on the side plate 2, and a side of metal fixed block 7 and metal clips 8 respectively is provided with a signal binding post 5; Metal fixed block 7 and metal clips 8 are fixed on the top of base plate 6; And metal fixed block 7 is positioned at the opposite of metal clips 8, is provided with the gap between metal fixed block 7 and the metal clips 8, and the other end of alloy memory spring 9 is fixed on the metal clips 8; Side plate 2 is the part of base plate 6, is positioned at the sidepiece of base plate 6.
Wherein the gap between metal fixed block 7 and the metal clips 8 is 1mm; Plain conductor 4 is flat serpentine and distributes in the cavity of alloy memory spring 9; The immediate set temperature of alloy memory spring 9 is 50 degree; The resistance of plain conductor 4 is 50 ohm, and alloy memory spring 9 is the memory titanium alloy material, and it is 50 degree that alloy memory spring 9 is set critical deformation temperature.
