Specific embodiment
As shown, a kind of bifilar fuse knits angle protractor, including quadrangle Angle protractor, four interior angles of Angle protractor
Wherein first interior angle 1 is that first met the bifilar fuses of series connection of aviation fasteners in braiding process buckles entanglement angle
120 °, second interior angle 2 is to meet intermediate in braiding process of the bifilar fuses of series connection of aviation fasteners to buckle entanglement angle
60 °, third interior angle 3 is to meet the ending of the bifilar fuses of series connection of aviation fasteners in braiding process to buckle entanglement angle
80 °, the 4th angle position is handle portion 4；It is bifilar by handle portion positioning holding quadrangle Angle protractor in braiding process
Quadrangle Angle protractor is overturn when fuse is entangled to different parts and is converted into respective top angular alignment bifilar fuse entanglement position, i.e.,
It can quickly detect whether entanglement angle meets prescribed requirement, read detailed angular readings without slowly comparison, it is easy to operate.
Diagonal distance longest between first apex angle and third item angle of quadrangle Angle protractor, first apex angle and
Diagonal distance is 80mm~100mm between three item angles；Specifically, first apex angle of quadrangle Angle protractor and third item
Diagonal distance is 80mm between angle；It occupies little space, measures easy to operate.
Quadrangle Angle protractor be located at handle portion apex angle be it is arc-shaped, meet ergonomics, operator's hand will not be abraded
Portion's skin increases gripping comfort level.
First interior angle, second interior angle, the third interior angle of quadrangle Angle protractor are labeled with respective angles numerical value respectively,
Intuitive is good.
For quadrangle Angle protractor with a thickness of 1.5~2mm, quadrangle angulation plate material is ferrite abrasion-proof stainless steel, corrosion-resistant
Performance is good, will not wear, long service life.
Bifilar fuse of the invention knits angle protractor, first interior angle of quadrangle Angle protractor, second interior angle,
Third interior angle corresponds with that the bifilar fuse of series connection of aviation fasteners first buckle in braiding process, centre buckles, finishes up
The entanglement angle of button, by handle portion positioning holding quadrangle Angle protractor, turning-over changed apex angle alignment is bifilar in braiding process
Fuse entanglement position can quickly detect entanglement angle, read detailed angular readings without slowly comparison, structure is simple, intuitively
Property it is good, easy to operate, work efficiency is high, can accurate each position entanglement angle, anti-loosening effect is good, and safety coefficient is high.
Specific technical solution:
On aircraft, firm part loosens in order to prevent, usually uses and is connected on two or more points with fuse
Together, restrain them mutually, the activity of any one point will all will receive the limitation of other points, to reach locking mesh
's.Bifilar fuse is one of method.It is knitted in the 147 basic skills real trainings in order to reach connector about bifilar fuse
Angle measurement buckled in braiding process the first of knot according to bifilar fuse, the intermediate entanglement angle buckled of buckleing and finish up is
It is different, bifilar fuse braiding process its knit angle have conventional method be entirely by estimate, without dedicated measurement
Tooling.
It is an object of the invention to 3 different angles of the bifilar fuse in braiding process are comprehensive in a tooling
On, meet bifilar fuse 60o, 80o, 120o measurement request in braiding process,
The present invention relates to the measurements in 147 basic skills real trainings about bifilar fuse woollen yarn knitting angle.
The invention discloses a kind of bifilar fuses to knit angle rapid survey tooling, it is characterized in that bifilar fuse is compiled
Three kinds of angles needed for knitting are comprehensive in a measurement measurement plate, respectively 60o, 80o, 120o.
Setting interlocking hole, fuse pass through the interlocking on starting point nut on the nut of two or more fastening points
Kong Hou, it is bifilar fuse that both ends are tangled according to the operating procedure of regulation, buckle positioned at the first of bifilar fuse entanglement starting point,
It tangles to the intermediate button that finishes up detained, continue to tangle after second nut first line of a couplet lockhole before second nut first line of a couplet lockhole
Entanglement angle passes through the detection of quadrangle Angle protractor respectively and verifies whether to meet prescribed requirement, and can be adjusted by quadrangle Angle protractor
To prescribed requirement is met, after all nuts of interlocking that tangle, final tangle to fixed point is fixed is locked, and fixed point can be set
On final nut, equipment surface near final nut also can be set or an independent nut can also be by double
The fixed interlocking of stock fuse is nearby in equipment surface；It is fixed by handle portion when the first of bifilar fuse entanglement starting point is buckled
Position holds quadrangle Angle protractor, and handle portion is diagonally 120 ° of first interior angle for meeting the first button entanglement angle requirement, passes through hand
Shank positioning holding quadrangle Angle protractor can directly detect verifying first button entanglement angle whether meet prescribed requirement, and adjust to
Meet prescribed requirement；Bifilar fuse tangles to second nut first line of a couplet lockhole intermediate when buckle, is positioned and is held by handle portion
Quadrangle Angle protractor is held, apex angle is 60 ° of second interior angle for meeting intermediate button entanglement angle requirement above handle portion, passes through handle
Portion's positioning holding quadrangle Angle protractor can directly detect whether the intermediate button entanglement angle of verifying meets prescribed requirement, and adjust to symbol
Close prescribed requirement；Bifilar fuse passes through the ending that continues after second nut first line of a couplet lockhole to tangle when buckleing, and is positioned by handle portion
Quadrangle Angle protractor is held, apex angle is 80 ° of third interior angles for meeting ending button entanglement angle requirement below handle portion, passes through hand
Shank positioning holding quadrangle Angle protractor and overturn it is upward to third interior angle, can directly detect verifying ending button entanglement angle whether
