Description
Technical field
Present invention relates particularly to a kind of plastic product nut riveting device.
Background technology
Plastic product often use nut riveting device it is installed; nut riveting device is a kind of instrument being rotated by driven by motor driver bit and realizing automatic tightening screw; the driver bit of traditional nut riveting device is the most exposed; therefore driver bit usually can collide with some hard things; so driver bit will soon deform; causing driver bit not using, or skidding occur when using, therefore driver bit reduces the life-span of driver bit；Therefore the output shaft of motor is set to retractable spindle, then driver bit can be hidden when output shaft shrinks, thus reach to protect the purpose of driver bit.Due to when using nut riveting device, motor output shaft is in addition to providing moment of torsion, also need to undertake the axial force of movement, therefore after only being completed elongation by air pressure or electric magnet after motor exports, probably because axial force is excessive, and output shaft is compressed, cause nut riveting device normally not use.
Summary of the invention
Can not be compressed by axial force after it is an object of the invention to provide a kind of output shaft telescopic plastic product nut riveting device, and output shaft elongation.
For reaching above-mentioned purpose, the base case of the present invention is as follows:
Plastic product nut riveting device includes that body, output shaft and activate switch, described body include stator and rotor；Described output shaft includes fixing end and telescopic end, and described fixing end is fixed with rotor, and fixing end is coated at telescopic end one end, and telescopic end only can slide along fixing end, and telescopic end is additionally provided with return spring；Being provided with indexing rotating cylinder, push rod and sliding pawl set in described fixing end, indexing rotating cylinder is fixing with fixing end to be connected, and push rod is slidably connected with indexing rotating cylinder, and sliding pawl set is placed on telescopic end end；Described indexing rotating cylinder is provided with spaced deep trouth and the shallow slot in ratchet-like, and described push rod and sliding pawl put and be provided with press strip and sliding pawl, press strip and sliding pawl and be provided with the inclined-plane cooperated；It is provided with, in described fixing end, the electric magnet that push rod can be promoted.
The principle of this programme plastic product nut riveting device is:
Promoting push rod by electric magnet, owing to sliding pawl set is placed on telescopic end end, therefore return spring will have a counteracting force to sliding pawl set, then the press strip on push rod will extrude the sliding pawl that sliding pawl puts；Owing to press strip and sliding pawl are provided with the inclined-plane cooperated, therefore during push rod extruding sliding pawl set, sliding pawl and press strip slide along its inclined-plane contacted, and sliding pawl set can rotate.When the set that trackslips rotates, sliding pawl will be corresponding with the deep trouth on indexing rotating cylinder and shallow slot successively；The release pressure to push rod, sliding pawl set and telescopic end together by return spring fight back, are then slided pawl and are then snapped in deep trouth or the shallow slot of correspondence.Due to deep trouth and shallow slot, to have groove depth poor, and therefore when sliding pawl is fastened in deep trouth, telescopic end will be retracted to fixing end, and output shaft shrinks；And when sliding pawl is fastened in shallow slot, telescopic end will stretch out from fixing end, output shaft extends.
This programme produces and provides the benefit that:
(1), this programme promote push rod by electric magnet, the flexible of motor output shaft can be realized, control simple and convenient；
(1), time sliding pawl set is fastened in shallow slot in this programme, output shaft extends, and owing to shallow slot is ratchet-like, therefore slides pawl set top and be pressed on indexing rotating cylinder and will be stuck, and i.e. after telescopic end is by axial force, output shaft also will not be compressed.
Preferred version one: as the further optimization to base case, described fixing end is hollow axle, and described electric magnet is fixed on stator, and described push rod is provided with the permanent magnet relative with electric magnet.Electric magnet is fixed on stator, is conducive to power transmission line of arranging；After electric magnet is energized, permanent magnet is repelled each other, thus reach to promote the purpose of push rod；Fixing end is set to hollow axle, and beneficially electric magnet is fixed on stator.
Preferred version two: as the further optimization to base case, also include that impulse current generator, described electric magnet are connected with impulse current generator.After promoting push rod, it is necessary to unclamp push rod, sliding pawl set could be engaged in corresponding deep trouth or shallow slot under the effect of return spring, and without applying pressure to push rod for a long time；It is thus desirable to provide instantaneous thrust to push rod, and impulse current generator is set, presses respective switch and can produce instantaneous thrust, make more convenient operation.
Preferred version three: as the further optimization to base case, described activate switch is also connected with impulse current generator, presses activate switch with this, can control output shaft rotation simultaneously and output shaft stretches, make simple to operation further.
Preferred version four: as the further optimization to base case, the cross section of described telescopic end is regular hexagon, and described fixing end is provided with the regular hexagon hole coordinated with telescopic end；This preferred version can make the sectional area of external part more greatly, therefore can improve the intensity of output shaft.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference in Figure of description includes: stator 1, rotor 2, fixing end 31, telescopic end 32, push rod 33, indexing rotating cylinder 34, sliding pawl set 36, return spring 37, electric magnet 41, permanent magnet 42, deep trouth 51, shallow slot 52.
Embodiment is the most as shown in Figure 1:
The plastic product nut riveting device of the present embodiment includes body, output shaft and activate switch, and body includes stator 1 and rotor 2；Output shaft includes fixing end 31 and telescopic end 32, fixing end 31 is fixed with rotor 2, the cross section of telescopic end 32 is hexagonal, fixing end 31 is hollow axle, fixing end 31 axles are inserted in telescopic end 32 one end, and telescopic end 32 can slide in fixing end 31, fixing end 31 is provided with the hexagonal hole coordinated with telescopic end 32；Making when rotor 2 drives fixing end 31 rotation, fixing end 31 can drive telescopic end 32 to rotate.
