The specific embodiment
Further set forth technical characterstic of the present invention below in conjunction with accompanying drawing and specific embodiment.
Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, a kind of computerized lockstitch sewing machine driven by double motors comprises fuselage 1, circuit control panel 16, main servo motor 2, is contained in the radiator fan 17 on the main shaft 2; Main shaft 2 is in transmission connection with lower shaft 6 by synchronizing wheel 4, Timing Belt 5; The end of lower shaft 6 is equipped with by bearing and lifts tooth eccentric wheel 7, and bearing outside enters feed lifting rock shaft crank 8; Feed lifting rock shaft crank 8 is in transmission connection with work feed frame 10 by lifting tooth connecting pin 9; Feed dog 11 is installed on the work feed frame 10; Work feed servomotor 12 is screwed by rigging pilotage and bearing; The endoporus socket of the driving shaft of work feed servomotor 12 and rigging pilotage 13 and swing span 14 is also passed through screw lock; The upper end of swing span 14 swings with work feed frame 10 synchronously by pendulum tooth connecting pin 15; Feed dog 11, work feed frame 10 and swing span 14 mix proportions are cloth feeding mechanism intermittently.
Electronic control box shell 19 is equipped with on described computer flat sewing machine fuselage 1 interior right side, and electronic control panel 16 and computer chip are installed in the electronic control box shell 19.
Square hole is left in fuselage 1 front, described computer flat sewing machine right side, and control panel display 18 is installed in the square hole, so that operation and observation.
Main servo motor 2 is transferred to main shaft 3 through connector, main shaft 3 is equipped with radiator fan 17 and passes to lower synchronizing wheel 4 with synchronizing wheel 4 through Timing Belt 5, lower synchronizing wheel 4 links to each other with lower shaft 6, the end of lower shaft 6 is equipped with to lift presses tooth eccentric wheel 7, the eccentric shaft of lifting tooth eccentric wheel 7 is equipped with bearing, bearing outside enters feed lifting rock shaft crank 8, lifting rotatory force that tooth eccentric wheel 7 comes by main shaft 3 transmissions is transformed into up and down off-centre through wobbler action and lifts agomphiasis and do, lift agomphiasis and do through bearing with feed lifting rock shaft crank 8 with lift tooth connecting pin 9 and pass to work feed frame 10, be equipped with on the work feed frame 10 feed dog 11 cooperate swing spans 14 do about and exhaust work feed work between front and back.
Work feed servomotor 12 driving shafts directly penetrate swing span 14 endoporus, the work feed servomotor 12 driving shafts bearing of packing into is used screw lock through swing span 14 again, the other end is screwed by rigging pilotage 13 and bearing, the upper end of swing span 14 drives the 14 synchronous swing work of work feed frame through overswing tooth connecting pin 15, and work feed servomotor 12 is set the swinging distance working in reciprocating mode before and after doing according to the rotational position signal driving swing span of main servo motor 2.
As shown in Figure 6, flat seam machine work is that eedle is when moving downward the needle plate plane, feed dog 11 also sinks to the needle plate plane simultaneously and stops work feed because of the isolation of needle plate, the position of 12 a tree name main servos of work feed servomotor motor setting begins back to turn to former work feed position simultaneously, but being rotated further while feed dog 11, eedle when the needle plate lower plane will back rise to the plane, to finish swing span to former work feed position, when eedle continue to pass on moving when leaving the needle plate plane feed dog begin rising and exceed needle plate plane Tobe and begin work feed, work feed servomotor 12 begins again to cooperate feed dog 11 by the distance of setting work feed forward, the work that goes round and begins again.Therefore swing span 14 will cooperate feed lifting rock shaft crank 8, lifting the tooth work feed is according to the signal of needle plate plane as the reciprocal position of reference settings with falling tooth when stopping the work of work feed mutually, described lift the tooth position with the tooth position falls and can be according to mechanical movement needle plate plane as reference, set that main servo motor rotation respective angles is lifted tooth work feed swing position signal as triggering and back swing position signal of tooth falls in triggering.On the contrary, refund when seam, do not change just falling the upset of tooth trigger position signal for lifting the tooth signal because lifting the tooth direction, all cloth feeding directions reach against turnback refunds the seam purpose.Can set the work feed distance according to above action, flat seam machine work feed distance is set in 0 ~ 5mm scope usually, suppose that the work feed swinging distance of maximum 5mm must lift tooth triggering signal position and fall tooth triggering signal position inter-sync execution cycle work feed, continuation is finished the return swing from falling tooth triggering signal position with lifting the position inter-sync of tooth triggering signal, goes round and begins again.
