Description
Technical field
The invention belongs to textile machine, particularly a kind of needle fixation device of slide cam selector.
Background technology
At present, the needle fixation device of known slide cam selector has many kinds, has syringe needle and chuck to be connected, and also has a kind of by alignment pin locking pin, also has a kind of syringe needle to be the device clamped by colleting tongue.Syringe needle and chuck are connected as a single entity, and cannot change impaired syringe needle, and need change whole slide cam selector and cause unnecessary loss; Fixed by alignment pin, the replacing of pin can be realized, but when taking off alignment pin, because side direction is exerted oneself, easily damage driving chip; By colleting tongue gripping mechanism, can for convenience detachly change, but chuck tongue generation deformation after plug often, affect positioning precision, and the processing and manufacturing of intermediate plate is comparatively complicated.
Summary of the invention
Object of the present invention is exactly the deficiency for overcoming above-mentioned background technology, and provide one and be convenient to mounting or dismounting replacing, positioning precision is higher, and plug number of times is more, simultaneously the needle selector fixing device of the easier processing and fabricating of intermediate plate.
The needle fixation device of a kind of slide cam selector involved in the present invention, pin can removably, remain on a carrier.It is by a shank afterbody be can produce the pin of elastic displacement, band can be enclosed within pin and its chuck can limit the intermediate plate of pin position, be fixed on the outer cover plate of these intermediate plate both sides, and the link composition of driving chip is fixed to based on this two outer cover plate, intermediate plate and outer cover plate form pin folder jointly.
Pin is made up of syringe needle and shank, and shank afterbody is the tongue that can produce elastic displacement, and flat made by bar, at the tail width comparatively shank inswept of bar, to leave the mobile space producing elastic displacement, there is a screens breach tail end side, and opposite side tongue root has another tongue breach.Screens breach in tail end side makes pin press from both sides the projection press-in of chuck wherein under prestressed effect, thus realizes accurately location.
Pin folder chuck has the projection of a restriction pin position, protruding and screens breach coordinates makes pin locate, the width of intermediate plate is suitable with the width of shank, namely the fastening location of pin width is achieved upon insertion, because tongue design is at shank afterbody, the processing and manufacturing difficulty of intermediate plate comparatively has the intermediate plate of tongue greatly to reduce.
Protruding and breach is the circular arc cooperatively interacted, and by the size variation of radian, regulates the prestressing force of projection and breach, can realize adjustment that is fixing and plug tightness.
Outer cover plate, intermediate plate have a mark breach, and be the mark of the fashionable screens gap position of cushion, outer cover plate, outer cover plate carry out bonding with the link epoxy resin of driving chip.
The needle fixation device of a kind of slide cam selector involved in the present invention has to be convenient to mounting or dismounting and to change, and positioning precision is high, plug often, the simultaneously advantage of the easier processing and fabricating of intermediate plate.

Detailed description of the invention
Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.
The needle fixation device of this slide cam selector that Fig. 1, Fig. 2 represent, it can be produced the pin of elastic displacement by shank 2 afterbody, be limited the intermediate plate 4 of pin position, a chuck 3 that can be enclosed within pin is had in intermediate plate 4, two outer cover plates 5 are fixed on intermediate plate 4 both sides, and the link 6 of driving chip is fixed by two outer cover plates 5.
The pin of Fig. 1, Fig. 2, Fig. 6, expression, it forms by by syringe needle 1 and shank 2, syringe needle 1 forms primarily of the pinprick of circle, shank 2 afterbody is the tongue 7 that can produce elastic displacement, concrete structure is shown in Fig. 7, shank 2 makes flat, narrow compared with shank head end in the tail width of bar, to leave the mobile space producing elastic displacement; There is a concavity circular arc screens breach 8 tail end side, the radian of screens breach 8 is greater than the radian that pin presss from both sides 3 projections 10, the effect of pretightning force can be realized, on the right of screens breach 8, Aculeata width can design narrower, plug can be made so more easily to realize, and during plug, deformation is less, not easily causes permanent deformation, can increase the plug number of times of pin; Tail end opposite side tongue 7 root has another tongue breach 9, makes tongue 7 more easily produce displacement and can reply rapidly.As shown in Figure 3: the projection 10 that tail end side screens breach 8 makes pin press from both sides under prestressed effect is pressed into wherein, thus realize accurately location.Tongue structural design is at shank afterbody, and when syringe needle damages needle exchange, the tongue 7 producing deformation is changed with pin, adds the plug number of times of chuck 3, improves positioning precision simultaneously.
The pin folder of Fig. 1, Fig. 2, expression, it, by two outer cover plates 5, sees Fig. 5, and an intermediate plate 4, sees that Fig. 4 forms, and outer cover plate 5 tail end devises a circular hole 13; The width of intermediate plate 4 is suitable with the width of shank 2, and namely achieve the fastening location of pin width upon insertion, chuck 3 inserts at pin, and the importing end plugged all can be made in both sides; The thickness of intermediate plate 4 is suitable with shank 2 thickness, and pin can be plugged smoothly; Chuck 3 has the projection 10 of a restriction pin position, and projection 10 and screens breach 8 coordinate makes pin locate, and sees Fig. 3; The pin folder 3 of intermediate plate 4 has a mark breach 12, to distinguish the position, screens breach 8 direction of the fashionable tongue 7 of cushion.Because tongue design is at shank 2 afterbody, the aglossate spring structure of pin folder intermediate plate 4, therefore processing and manufacturing difficulty reduces greatly.Outer cover plate 5, intermediate plate 4 material spring steel, process by the method for punching press or laser cutting.Outer cover plate 5 is thinner than intermediate plate 4, and by the solder design at edge together, outer cover plate 5 rear portion exceeds intermediate plate 4, and hold the link 6 of driving chip in centre, outer cover plate 5 carries out bonding with the link 6 of driving chip with epoxy resin.
As shown in Figure 8, chuck 3 is inserted in shank 2, and namely pin inserts intermediate plate 4, and intermediate plate chuck 3 takes out, and namely pin is extracted, and its process is such:
Shank 2 afterbody has an inclined-plane 11, see Fig. 3, by it, the chuck 3 of intermediate plate 4 is inserted in shank 2 tail end, namely pin inserts intermediate plate 4, tongue breach 9 produces elastic deformation, screens breach 8 moves on to centre position B from original position A, when continuing chuck 3 to be inserted in, by returning elastically motion, screens breach 8 reaches clamping position C, chuck 3 protrusions 10 enters screens breach 8, screens breach 8 takes out at the chuck 3 of intermediate plate 4, namely time pin is extracted, move on to centre position B, the chuck 3 of intermediate plate 4 is continued to take out, by flexible return movement, screens breach 8 gets back to original position A again.
The present invention is by designing tongue on pin, and be convenient to mounting or dismounting and change, positioning precision is higher, and plug number of times is more, and intermediate plate is more easily processed simultaneously.
