The advantages of special, easy to connect, work efficiency is high.
Slide cam selector shell 1 in the utility model embodiment can pass through die carter using alloy (aluminium alloy, kirsite)
Skill is integrally formed, and the dimensional accuracy of such die casting key position (such as mounting plane, bar magnet plane, blade mounting holes) reaches
The precision prescribed of 0.02-0.04mm.In the prior art generally by being finished for skeleton blank part, production efficiency is low, speed is slow,
Precision is also difficult to reach the requirement in the utility model embodiment；Slide cam selector blade mounting holes position is that monoblock type powder metallurgy is embedding
Item, filler rod are strength structure part crucial when slide cam selector works, and hardness is HRC60 or more, to guarantee the wear-resistant and strong of axis hole
Degree, by long-term use, axis hole not abrasion deformation guarantees the mechanical precision and stability that slide cam selector works long hours to slide cam selector.
It is integrally formed when skeleton filler rod insertion skeleton die casting, guarantee the consistency of dimensional accuracy while improving production efficiency, subtracts
Few post-production cost.Meanwhile refering to shown in attached drawing 1,1 top and bottom of slide cam selector shell are slotted in the utility model embodiment
Setting increases heat dissipation area, reduces temperature when slide cam selector operation.After tested, slide cam selector shell 1 reaches reduction running temperature
10 DEG C or more of effect.
Moreover, the slide cam selector shell 1 in the present embodiment is designed using magnetic screen shell.The contact pin coil 4 of slide cam selector is by magnetic cup
Cover shell package (magnetic screen shell uses permalloy, the high permeability materials such as soft iron).The use of magnetic screen shell reduces slide cam selector line
Mutual magnetic interference when circle is powered on, blade screen resilience when operating slide cam selector blade level off to unanimously.It sends out after tested
Existing, it is 0.09-0.16N that blade screen resilience section corresponding to magnetic screen shell coil, which is not used, is using the power section of magnetic screen shell
0.1-0.13N.Each 5 screen resilience consistency of needle selection cutter head of slide cam selector is higher, and it is lower that blade when slide cam selector works falsely drops rate, blade
It swings sensitiveer (high-frequency), limit velocity is higher.
Refering to shown in attached drawing 1, attached drawing 2 and attached drawing 4, contact pin coil 4 and coil holder 8 and choosing in the utility model embodiment
The connection type of needle device shell 1 uses cannula type structure.Contact pin coil 4 uses cannula type structure, and coil holder 8 is equipped with positioning port,
Limiting slot, (positioning port, limiting slot machining accuracy can reach 0.02-0.04mm), when installation are equipped at 1 installation position of slide cam selector shell
Insertion positioning, while guaranteeing the size of coil capillary and the consistency in direction.In the prior art, conventional formula coil installation knot
Structure is multi-part buckle-type (spring, positioning sleeve, coil snap-gauge, glue), and component is more, and step is complicated and relies on manual operations, group
Inefficiency is filled, cannula type structure can be reduced number of components, reduce the process and difficulty of assembly, makes to assemble unification, makes product
Component models provide condition for Automated assembly production.Contact pin coil 4 and coil holder 8 and slide cam selector shell 1 are solid contact
Formula structure, and use heat production former (contact pin coil 4) and radiator (slide cam selector shell 1) for contact type structure in the prior art, heat
The temperature in source directly passes through radiator and forms high-efficiency heat radiation structure.Slide cam selector blade magnet steel demagnetization temperature is 150 DEG C, coil rack
Magnetic core demagnetization temperature is 200 DEG C, and coil rack plastic hot melt point temperature is 180 DEG C.Slide cam selector coil temperature is when reaching 170 DEG C
Because the decaying of magnetic force piece (needle-selecting blade, electromagnetic coil) magnetic force makes the reduction of slide cam selector operational efficiency.Through surveying, the choosing of cannula type solid conductive heat
Needle device can decline 40 DEG C of the hot temperature of slide cam selector electromagnetic coil under identical test environment (in contrast to air heat dissipation slide cam selector).This
Structure can guarantee the optimum operation temperature of electromagnetic coil and needle-selecting blade, and then improve the working limit speed of slide cam selector, improve
Blade hunting frequency reduces blade and falsely drops rate.
Meanwhile then the utility model embodiment in wiring board use contact pin mounting structure.After the insertion of contact pin coil 4 is fixed,
4 pressure surface of contact pin coil is higher than 1 baseplane 0.5mm of slide cam selector shell, and PCB circuit board passes through 6 pieces of spiral shells with a thickness of 1.5mm, wiring board
Silk is fixed, and when fixed screw, which is compacted contact pin coil 4 simultaneously, makes coil be fixed on slide cam selector.Screw positioning finishes while coil
Contact pin (16 pieces) is exposed to simultaneously on the outside of wiring board, and height, verticality, spacing are consistent, is processed convenient for automatic tin soldering station.And
Conventional line plate installs and uses wire-leading coil structure, and lead matter is soft, and stress can be bent, and causes Conventional coil scolding tin to need every and draws
Line is successively perforated, then is welded, and manual degree of dependence is big, and assembly efficiency is low.This contact pin type structure reduces assembly process, passes through zero
Part modular assembly improves assembly consistency, to improve stability.
Finally, the utility model embodiment uses sealing structure in magnetic action area.5 magnet steel of needle selection cutter head is ferromagnetism permanent magnetism
(3600gs), the easily impurity such as absorption iron filings, iron ash.Conventional skeleton structure needs air transmitted to radiate, and magnetic action area is open type, horizontal
Machine complete machine work Shi Yijin dust, the impurity such as wool yarn greasy dirt.Impurity, which enters, increases slide cam selector blade running resistance, causes to run
Velocity lag, it is not in place or directly stuck.The probability for reducing impurity and entering of magnetic action area sealing structure limits, reduces choosing
The maintenance cost of needle device, improves efficiency.
The preferable specific embodiment of the above, only the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art can readily occur in the technical scope that the utility model discloses
Change or replacement, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should
Subject to the scope of protection of the claims.
