Embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims limited range equally.
Shown in Fig. 1-2, the present invention relates to a kind of cable shield left and right sides stranding device, comprise lower carriage 1 and upper bracket 2, described upper bracket 2 lower ends engage with lower carriage 1 upper end, described lower carriage 1 is near being furnished with strip fixed head 11 around the bottom, on an end of the strip fixed head 11 in left side, servomotor 8 is installed, described servomotor 8 drives belt pulley 5 by Timing Belt 6 and rotates together, described belt pulley 5 is installed in the center of upper bracket 2, described belt pulley 5 centers are equipped with holds spool 4, described spool 4 centers of holding had line three-way hole 3, pass in the described excessively line three-way hole 3 and treat stranded cable core, the edge placement of close belt pulley 5 has the separated time basin 7 take belt pulley 5 centers as the center of circle around the described excessively line three-way hole 3, described separated time basin 7 can rotate with belt pulley 5, be uniformly distributed with shielding copper wire 9 in the described separated time basin 7, described shielding copper wire 9 rotates with separated time basin 7, one end of described shielding copper wire 9 links to each other with distributor plate 10 centers, the center of described distributor plate 10 is passed and is treated stranded cable core, described distributor plate 10 is with the shielding copper wire 9 of Different Exercise Mode and treat that stranded cable core twists together, described line three-way hole 3 sizes of crossing adapt with the cable core size of passing line three-way hole 3, the instruction that described servomotor 8 sets according to programmable logic controller (PLC) is also controlled servomotor 8 rotation directions and velocity of rotation by servo controller, and described distributor plate 10 centers are with to cross line three-way hole 3 centers contour and corresponding.
Be applied to control device of the present invention and comprise a man machine operation interface, the PLC of a tape pulse output and the Servocontrol device that is complementary with servomotor 8, at first, to treat that stranded cable core passed the center of line three-way hole 3 and distributor plate 10, guarantee to shield copper wire 9 and treat that stranded cable core specification is consistent and enough, then in man-machine interface, set technological parameter, such as the stranded angle in the left and right sides, speed, line speed etc., and startup PLC, by the PLC computing generation pulse train number corresponding with angle control, pulse frequency; When servo controller receives symmetrical expression positive negative pulse stuffing sequence instruction from PLC pulse output, positive and negative rotation direction and symmetrical displacement that servo controller drives servomotor according to direction and the frequency instruction of pulse signal.By the PLC image data, follow the tracks of line speed, the signal of then exporting a 0-10VDC is controlled the rotary speed of servomotor 8 to SERVO CONTROL.Because servomotor 8 carries encoder, encoder as the feedback signal source so that the control device of servomotor 8 can be good movement velocity, the displacement angle of control servomotor 8, realize accurate control to the operation of shielding copper wire 9 by the accurate control to servomotor 8, thereby guaranteed the stability of left and right sides moulding pitch.Take to the electromagnetic shielding of small interface electric wire as example, when the percentage of braiding coverage that requires the shielded type cable braid shielded requires to reach 80%, the general diameter 0.15～0.3mm of used copper wire, select according to different size, can surpass 90% such as the percentage of braiding coverage with the shielding of left and right sides stranding device twisted cable, can use less copper wire 30%, external diameter is little and smooth, and its operating efficiency is confidential higher tens times than common cable shielding braid.
