Description

Very-high-speed shielded line winder

The present invention relates to a kind of shielded wire winding machine.

Can protect the signal of telecommunication of the inner core copper cash of flowing through not in national economy, be widely used day by day by the shielding conductor of external electromagnetic field interference.And be very low as the production efficiency of the wrapping machine of producing shielding conductor, its reason is that the profile of this machine is vertical, be divided into and put on the shelf and undercarriage, coaxial irregular component is done coaxial rotatablely moving about having in the frame, also there are the out-of-alignment parts to rotate or rectilinear motion, bigger by component weight, as can be seen, this machine is higher to the requirement for dynamic balance of rotating parts, so the rotating speed of this machine is limited in 300 rev/mins, in case intending increasing rotating speed enhances productivity, will produce the entire machine vibration, can't produce, even terrible consequences might occur, study carefully its vibrative root, it is mainly:

1, the winding displacement pulley influence of paying: when take-up pulley is paid in take-up, its line is proper alignment up and down, depending on the winding displacement pulley pays at reverse-flighted screw and moves up and down, and pulley is paid away from pivot, and many weight is arranged, because its moving up and down reciprocatingly, center of gravity is changing, and consequent centrifugal force is also moving up and down, and lays particular stress on so produce inevitably, lose original dynamic balancing, the result causes the entire machine vibration, and machine rotational speed is higher, and centrifugal force is bigger, the non-equilibrium state shape that causes is just more serious, and entire machine also just vibrates more severely;

2, the change gear influence of paying: along with the shielding conductor of producing different size, the lay of its outsourcing copper cash is also different, and the size of hinge distance relies on change gear and varies in size the collocation of the number of teeth.But change gear was both paid and was revolved round the sun around axis, did rotation in the position of off-axis again, the variation of gear position, total number of teeth in engagement with different, the variation of gear weight has all destroyed the original balance of this machine, in case rotate, has increased the weight of the vibration of machine;

3, the structure of pay off rack: existing pay off rack is pinion stand, and backguy seat and left and right support are formed, and material is a cast iron, and this structure is more numerous and diverse, and weight is bigger, and assembly precision is had relatively high expectations, and moment of inertia is big, is another main cause that this machine produces vibration source.

The objective of the invention is to overcome above-mentioned the deficiencies in the prior art part, and a kind of ultrahigh speed (n＞800 rev/min) shielded wire winding machine is provided.

The present invention is achieved by the following scheme:

1, having the dynamic object corresponding 180 of certain distance to spend at pivot disposes the movable weight that is equal to weight with dynamic object, dynamic winding displacement pulley is paid the dynamic counterweight of giving servo-actuated on the positions;

2, make and both to revolve round the sun around axis that the moment of inertia of doing rotation again in the position of off-axis is a constant, it is constant promptly to produce two gear shaft centre-to-centre spacing that the change gear of the shielding conductor of different laies pays, and two number of teeth sums are a constant number, being equal in weight of each gear;

3, pay off rack is the monoblock cast structure;

Advantages such as that the present invention has is simple in structure, production efficiency is high, safe and reliable for replacing original shielded wire winding machine, have vast market prospect.

Below in conjunction with accompanying drawing the present invention further is described in detail for example

Part

See accompanying drawing 1,2, when motor 5-1 orders about take-up stand 3-1 around rotational by power transmission shaft 5-2, simultaneously also order about change gear and pay 4-1 by driving-chains such as fixed wheel 5-3,4-2 rotates, and the reverse-flighted screw 3-2 that drives on the take-up stand 3-1 rotates, making the reciprocal nut that has the winding displacement pulley on the reverse-flighted screw 3-2 pay the reverse-flighted screw 3-2 of 3-3 in take-up stand 3-1 moves up and down, the reciprocal nut that has a winding displacement pulley is paid on the take-up stand 3-1 at two ends, reverse-flighted screw 3-2 position at 3-3 place and respectively has been installed with a single groove pulley 3-41,3-42, and on the take-up stand 3-1 of the reverse-flighted screw 3-2 of corresponding another side end positions, respectively be installed with a double grooved pulley 3-51,3-52, the reciprocal nut that has a winding displacement pulley is paid its upper end of 3-3 and is connected with steel wire fly 3-6, steel wire rope 3-6 walks around single groove pulley 3-42, double grooved pulley 3-52, the groove of 3-51, link to each other with the lower end that is equal in weight in the reciprocal nut that has the winding displacement pulley is paid the dynamic equilibrium piece 3-7 of 3-3, another root steel wire fly 3-6 one end is connected in the lower end that the reciprocal nut that has the winding displacement pulley is paid 3-3, and walk around single groove pulley 3-41, double grooved pulley 3-51, another groove of 3-52, link to each other with the upper end of dynamic equilibrium piece 3-7, dynamic equilibrium piece 3-7 is threaded on the reverse-flighted screw 3-2.When the reverse-flighted screw 3-2 on the take-up stand 3-1 rotates, the reciprocal nut that has a winding displacement pulley is paid 3-3 and is moved up and down on reverse-flighted screw 3-2, when it down moves, the steel wire rope 3-6 that lies in its upper end also moves down synchronously, and walk around single groove pulley 3-42, double grooved pulley 3-52,3-51 and the steel wire rope 3-6 that lies in dynamic equilibrium piece 3-7 lower end also pull dynamic equilibrium piece 3-7 on reverse-flighted screw 3-2 to going downwards to, in like manner, when reciprocal nut is paid 3-3 and is upwards moved, dynamic equilibrium piece 3-7 moves upward under the effect of steel wire rope 3-6 synchronously, clearly, during take-up stand 3-1 running, the reciprocal nut 3-3 that has the winding displacement pulley is in eccentric state, on it, following motion is produced lays particular stress on the dynamic equilibrium piece 3-7 that centrifugal force all is synchronized with the movement and has balanced.

See accompanying drawing 3, when motor 5-1 orders about take-up stand 3-1 around rotational by power transmission shaft 5-2, simultaneously also pass motion to planetary gear 5-4 by fixed wheel 5-3, planetary gear 5-4 will move successively again and pass idle wheel 5-5, drive 5-6, pass motion to change gear at last and pay 4-1,4-2, change gear 4-2 drives reverse-flighted screw 3-2 and rotates, change gear is paid 4-1,4-2 is in the rotational of self, also under the drive of take-up stand 3-1, revolve round the sun, pay 4 because of the shielding conductor of producing the different size lay needs the often replacing except that change gear, all driving sections 5 are all constant, pay 4-1 at the change gear of changing the different numbers of teeth, during 4-2, making the joint garden radius sum of its two gear is a constant, that is diaxon distance is a fixed number, and method is to make every pair of change gear pay 4-1, the number of teeth of 4-2 and be a constant number, as shown in the table:

The lay change gear table of comparisons

Need each gear that the change gear of conversion pays 4-1,4-2 by conversion material (as No. 45 steel and nylon MC901 etc.), width of cloth portion loss of weight (hollow out or the end face brill also waits), means such as counterweight are equal in weight it.It is constant to the distance of the pivot of take-up stand 3-1 just to guarantee that change gear is paid 4 centers of gravity, good with regard to balance in advance because unconverted change gear is paid 4 centrifugal force.
