Detailed description of the invention
As Figure 1-4, the differential governor motion of Sewing machines amplitude described in the utility model embodiment, comprise shell fabric jacking-machine structure and lower floor's fabric jacking-machine structure, these two wrinkling mechanisms of upper and lower shell fabric are made up of upper tooth pushing structure, lower tooth pushing mechanism respectively successively and pass through to control to coordinate with the inside and outside presser feet of Sewing machines itself and tooth, thus controlling the wrinkling amplitude of upper and lower shell fabric, sewing goes out qualified product of all kinds;
For more than, upper tooth pushing vibrational power flow driven shaft 2 wherein and connecting with machine spindle, synchronous pulley 1 drives driven shaft 2 to rotate by Timing Belt, it is reciprocating that the eccentric wheel 3 be arranged on driven shaft 2 promotes connecting rod 4, and described connecting rod 4 arranged outside controls the differential attachment that can change amplitude by synchronous motor, this differential attachment is by synchronous motor 7, change-speed gearing 1 and change-speed gearing 26, rocker 9, rocker axle 8, pitman shaft 10 and connecting rod 2 11 form, rocker axle 8 wherein and driven gear shaft are fixedly connected on rocker 9, and rocker axle 8 and driven gear shaft are arranged in frame by bearing, the corner of control synchronization motor, rocker corner can be controlled, each connecting rod 2 11 one end is connected with promotion connecting rod 1 by bearing, be positioned at the respective other end of the connecting rod 2 11 of both sides to be arranged on by bearing and to be fixed on pitman shaft 10, the other end of two connecting rods 2 11 at middle part is arranged on the input of pendulum plate 13 by bearing, these four connecting rod 2 11 one end are installed on the same axis, and when the axial line that synchronous motor controls four another stomidiums of connecting rod 2 11 overlaps, no matter how eccentric wheel 3 promotes push rod 4 is moved, and pendulum plate 13 and mechanism are below without a bit motion.
Correspondingly, be positioned at pendulum plate 13 outside to be connected with transition axis 15 by connecting rod 5 14, connecting rod 6 16 successively, along with synchronous motor controls the increasing of rocker 9 deflection angle, four connecting rod 2 11 other ends deviations that are middle and two lateral opening axial lines strengthen, pendulum plate 13 also strengthens around the amplitude of pendulum plate axle 12, thus promotes upper and lower transition axis 15 is swung; The swing arm 17 be fixed on transition axis 15 makes upper tooth pushing bar 23 make front-rear reciprocation movement along with the swing of transition axis 15, and upper tooth pushing bar 23 two ends, respectively with lower tooth pushing 22, upper tooth pushing 26, are positioned in the middle part of tooth pushing bar 23 and install push pedal 24; When cylinder 25 bar stretches out, press tooth pushing bar 23 rear end downwards by cylinder head 19, connecting rod 3 18, connecting rod 4 21, transiting rod 20, the front end that tooth pushing is housed tilts, and now goes up wrinkling mechanism and is in released state; When cylinder 25 bar shrinks, tooth pushing bar 23 rear end in pull-up, upper tooth pushing 26 pushes down shell fabric, after outer presser feet pushes down fabric, interior presser feet lifts and moves forward, with on tooth pushing bar 23 move backward, thus making fabric wrinkling, this is sewing machine seam at present, then can reach should be effective; When Sewing machines feeding, external pressure feet lifting rises, and the locating clip be fixed on outer presser bar lifts, thus holds up upper tooth pushing bar 23 leading portion, and upper tooth pushing 26 is lifted and is separated with fabric, is convenient to Sewing machines feeding.
As shown in Figure 2, lower tooth pushing structure is wherein substantially identical with upper tooth pushing structure, namely the synchronous pulley 1 of synchronous pulley II 1101 and driven shaft II 1102 and Fig. 1 and driven shaft 2 are same wheels and same axle, except transition axis II 1115, outside connecting rod 6 II 1116 length difference, synchronous pulley II 1101 to connecting rod 6 II 1117 function is identical with Fig. 1 synchronous pulley 1 to swing arm 17, the connecting rod 6 II 1117 be fixed on transition axis II 1115 makes cylinder head II 1119 make front-rear reciprocation movement along with the swing of transition axis II 1115, lower tooth pushing II 1122 connects firmly on cylinder head II 1119 by upper tooth pushing bar II 1123, because the pulling force of spring, on the transiting rod II 1120 connecting rod 4 II 1121 be packed on cylinder head II 1119 being pressed in be packed on lower shaft, after outer presser feet pushes down fabric, interior presser feet lifts and moves forward, along with cylinder head II 1119 moves backward, thus make lower floor's fabric cycling start seam, when Sewing machines feeding, external pressure feet lifting rises, and interior presser feet and walking tooth are clamped fabric and done feeding campaign along with the needle, and transiting rod II 1120 depresses cylinder head II 1119 simultaneously with it, thus lower tooth pushing II 1122 declines and departs from fabric, is convenient to Sewing machines feeding, when cylinder II 1125 bar stretches out, upper tooth pushing II 1126 pressure is fixed on the push pedal II 1124 of cylinder head II 1119 bottom, then descend tooth pushing II 1122 to decline, and can not shift lower floor's fabric onto, now lower floor's fabric then can not rise wrinkling, can only flush joint.
The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
