Square hole is left in fuselage front, described computer flat seam machine right side, and the control panel display is installed in the square hole, so that operation and observation.
Root a tree name industrial flat bed sewing machine operation principle of the present invention is in conjunction with machinery and electron controls technology and servomotor simultaneous techniques, armature spindle with a servomotor directly penetrates the swing span endoporus, drive the swing span swing with screw-driving, the swing span upper end connects the work feed frame by pendulum tooth connecting pin, the work feed frame other end passes feed lifting rock shaft crank through connecting pin, feed lifting rock shaft crank lower end endoporus is equipped with lifts tooth eccentric shaft and bearing, lifts tooth off-centre and is connected on the power transmission shaft, and power transmission shaft is with through synchronously and is linked to each other with the main servo motor.In the right fuselage of computer flat seam machine of the present invention, original mechanical part and electromagnet component are removed, leave enough spaces and assemble electronic control box, the shape of electronic control box is installed internal body according to shape structural design in the space in the right body of computer flat seam machine and is guaranteed that circuit safety reliably reaches heat radiation.The positive plane of the right body of computer flat seam machine is partly opened a square opening and is assembled display and operation push-button, makes the more computer flat seam machine of electromechanical integration of complete machine, overcomes the structure that flat seam machine head and electric cabinet in the past divide two parts.
Computer flat seam machine by the present invention designs has following beneficial effect:
1, the present invention is directly installed on the computer flat seam machine work feed frame with an independent work feed servomotor, cooperates the framing signal of the main servo motor of the driving main shaft work feed that moves back and forth synchronously.Remove mechanical part and electromagnet assemblies such as mechanical linkage and oscillating cam, reduce rotational noise and vibration.
2, can refund seam automatically and manually refund joint working by the synchronous execution in upset operating position that main motor is set, improve the seam speed of refunding simultaneously.
3, the present invention can solve oil-free lubrication and pollute and also reduce flat seam machine mounting technology and manufacturing cost and technology simultaneously, and easily produces in batches.
4, the present invention settles the flat seam machine right side then in the body computer main control box, makes flat seam machine more integrated also more reliable and more stable, saves computer control cabinet independently casing and packing and variously expose patch cord and electricity is look at.
5, display can be installed in before the body right-hand, more in operation observation.

The specific embodiment
Further set forth technical characterstic of the present invention below in conjunction with accompanying drawing and specific embodiment.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4 and shown in Figure 5, a kind of Dual-motors Driving computer flat seam machine 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 by synchronizing wheel 4, be with 5 to be in transmission connection with lower shaft 6 synchronously; The end of lower shaft 6 is equipped with by bearing and lifts tooth eccentric wheel 7, and bearing outside is gone into 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; Swing with work feed frame 10 synchronously by pendulum tooth connecting pin 15 upper end of swing span 14; Feed dog 11, work feed frame 10 and swing span 14 cooperate forms intermittently cloth feeding mechanism.
Electronic control box shell 19 is equipped with on the right side in the described computer flat seam machine fuselage 1, and Electronic Control plate 16 and computer chip are installed in the electronic control box shell 19.
Square hole is left in fuselage 1 front, described computer flat seam machine right side, and control panel display 18 is installed in the square hole, so that operation and observation.
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 to cooperate feed dog 11 by the distance of setting work feed forward, the work that goes round and begins again 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 tooth swing position signal back falls in triggering.On the contrary, refund when seam, do not change just falling the upset of tooth trigger position signal because of lifting the tooth direction for lifting the tooth signal, 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.
