Abstract
The utility model relates to a needle selector, in particular to an eight-section wear-resistant needle selector. The eight-section wear-resistant needle selector comprises a support, coils, a circuit board, a needle selecting blade, a left side plate and a right side plate. The circuit board is installed at the bottom of the support. The circuit board is externally connected with a power source. The coils are installed on the left side plate and the right side plate and are connected with the circuit board through leads. The left side plate and the right side plate are fixed to the two sides of the support. The needle selecting blade is fixed and located to the end of the support through a hinge pin and an end cap. The two sides of the needle selecting blade are inwards recessed. The angle of a too bit of the needle selecting blade ranges from 120 degrees to 140 degrees. According to the design scheme, the angle of the tool bit of the needle selecting blade is changed, so that the stress of the work surface of the blade is reduced, as a result, wear of the blade is relieved, and therefore the eight-section needle selector is resistant to wear.
Description
Technical field
The utility model relates to a kind of slide cam selector, is eight sections of wear-resisting slide cam selectors specifically.
Background technology
Current existing slide cam selector, the complex structures such as support, processing trouble, production cost is higher, in addition, and current general Eight-section needle selector, the cutter head angle of its needle-selecting blade is respectively 100 degree, 110 degree and 120 are spent three kinds, and this kind of blade weares and teares comparatively fast at work, and the life-span is not long.Therefore use cost is higher, also can produce waste product because of blade abrasion.
Utility model content
For the problems referred to above, the utility model has changed the angle of the cutter head of needle-selecting blade, thereby has changed the stressing conditions of blade work face, has reduced the stressed of blade work, thereby has slowed down the wearing and tearing of blade, makes our Eight-section needle selector become wear-resisting slide cam selector.
The utility model is achieved through the following technical solutions: a kind of eight sections of wear-resisting slide cam selectors, comprise support, coil, circuit board, needle-selecting blade, left plate, right plate, described circuit board is installed on the bottom of support, the external control power supply of described circuit board, coil is arranged on left and right side plate and is connected with circuit board with wire, left and right side plate is fixed on the both sides of support, needle-selecting blade is fixed and is positioned the end of support by bearing pin and end cap, the both sides of described needle-selecting blade concave, and the cutter head angle of described needle-selecting blade is 120 ° ~ 140 °.Cutter head angle can be selected 120 °, 125 °, 140 ° etc.
As preferably, described left plate and right plate are " Π " shape.
As preferably, the described support fixedly two sides of left and right side plate is set to the framework of hollow out, and described left plate and right plate are fixed by screw and support, the framework that the bottom of described support mounting circuit boards is hollow out.
Certainly the bearing pin in the utility model is 8, offers 8 openings on end cap, and coil has 8, each 4 of left and right, needle-selecting blade has 8, and needle-selecting blade can select a kind of angle to be applied on all blades in the scope of cutter head angle, can be also to select each some of two kinds of angles.
The utility model has been taked after abovementioned technology, its beneficial effect is remarkable: the advantage of the technical program is the angle that has changed blade work face, thereby has changed the stressing conditions of blade work face, has reduced the stressed of blade work, thereby slowed down the wearing and tearing of blade, extended its working life.Revise support and increased the side plate of two Π shapes.After support is revised, the difficulty of processing of support has reduced, having reduced with material of support, the production cost of support has also decreased, the side plate of the two Π shapes that increase is used for fixing coil, and the positioning precision of coil has improved, thereby the operating accuracy of needle-selecting blade and reliability are all improved.
Accompanying drawing explanation
Fig. 1 is the general assembly explosive view of the utility model embodiment 1;
Fig. 2 is the structural representation of the needle-selecting blade of the utility model embodiment 1;
Fig. 3 is the fundamental diagram of the needle-selecting blade of the utility model embodiment 1.
In figure, 1 is support, the 2nd, and right plate, the 3rd, left plate, the 4th, coil, the 5th, circuit board, the 6th, needle-selecting blade, the 7th, bearing pin, the 8th, end cap, the 9th, pin.
The specific embodiment
Contrast accompanying drawing is below further described the utility model in conjunction with the embodiments.
Reference is as Fig. 1, shown in Fig. 2, these eight sections of wear-resisting slide cam selectors, by support 1, left plate 3, right plate 2, coil 4, circuit board 5, needle-selecting blade 6, bearing pin 7, end cap 8 compositions such as grade, left plate 3 and right plate 2 are " Π " shape, support 1 is fixing left, the two sides of right plate 2 are set to the framework of hollow out, the bottom of support 1 mounting circuit boards 5 is also the framework of hollow out, coil 4 is arranged on a left side, on right plate 2, also with wire, be connected and accept external control power supply with circuit board 5, left plate 3 and right plate 2 are installed respectively four coils 4, then left plate 3 and right plate 2 are fixed by screws in support 1 both sides, circuit board 5 is installed on the bottom of support 1, it is fixing and be positioned the end of support 1 by bearing pin 7 and end cap 8 that four cutter head angles are the needle-selecting blade 6 of 134 ° and the four cutter head angles needle-selecting blade 6 that is 124 °, wherein the both sides of needle-selecting blade 6 concave.After external control Power supply, coil produces magnetic field, produces phase suction or mutual expelling force with the permanent magnet on needle-selecting blade 6, thereby makes needle-selecting blade 6 produce and swing around bearing pin 7.
Shown in Fig. 2, Fig. 3, the Wear Resistance Mechanism of this wear-resisting slide cam selector is needle-selecting blade.As shown in the figure, needle-selecting blade, by illustrated movement locus motion, acts on pin.The operation principle of its slide cam selector is: when slide cam selector is worked, if a certain pin work, its blade as shown sample clashes into this pin, by blade work inclined-plane, depresses this pin downwards, makes this pin in running order.
The angle of the cutter head of needle-selecting blade is 2 β, pin can normally be worked, must guarantee certain downward force (F2), guarantee under the prerequisite of downward pressure (F2), along with the variation of the cutter head angle of needle-selecting blade, power in its direction of motion (F1) also changes thereupon, according to illustrating mechanics mould and trigonometric function knowledge: F2=tg β * F1, along with the increase at β angle, the value of tg β also increases, if F2 remains unchanged, must be that F1 reduces.Otherwise we increase angle 2 β of the cutter head of needle-selecting blade, guaranteeing, under the prerequisite of the normal work of slide cam selector, just to reduce the impact between cutter head and pin, thereby improving the working life of the blade of slide cam selector, slow down the wearing and tearing of slide cam selector blade.
What more than enumerate is only specific embodiment of the utility model, and obviously, the utility model is not limited to above embodiment.All distortion that those of ordinary skill in the art can directly derive or associate from the disclosed content of the utility model, all should belong to protection domain of the present utility model.
