Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Embodiment in the utility model, those of ordinary skill in the art are not doing other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model is described in detail with embodiment below in conjunction with accompanying drawing.
Embodiment 1: a kind of sewing machine garment piece sews up automatic arranging device, it has sewing machine dials 1, be positioned at the sewing machine cantilever 11 above sewing machine dials 1 and the knife bar of drive needle sports that is installed on sewing machine cantilever cranks arm 12, described sewing machine cantilever 11 is connected with garment piece simultaneously and sews up automatic arranging device 2, this garment piece stitching automatic arranging device 2 is provided with by pedestal 21, fork 22, first connecting rod 23, second connecting rod 24 and leading section the push rod 25 arranging block 251 and forms.The present embodiment fork 22 is provided with rotary middle spindle 221 and is installed vertically on pedestal 21, upper end, rotary middle spindle side is provided with horizontal fork, make described knife bar crank arm 12 drive suture needle reciprocating motion time can touch its side end, rotary middle spindle opposite side bottom is provided with the contrary horizontal fork in direction, this horizontal pendulum boom end is provided with slide block 222, slide block 222 is connected in the chute of first connecting rod 23 one end, first connecting rod 23 other end is through the first guide chute seat 2231 and second connecting rod 24 one end Joint, the second connecting rod other end connects with push rod 25 one end, the push rod other end is through sliding chute seat 258, push rod 25 stage casing is made to be arranged in the chute hole 259 of sliding chute seat 258, and back-moving spring 252 is set with in the push rod section being positioned at chute hole, the push rod section of back-moving spring rearward end is provided with spring pushing pin rod 253, radial level elongated slot 254 is offered in push rod 25 leading section, horizontal pendulum plate 255 is through horizontal elongated slot 254, its one end is fixing arranges block 251, the other end is movably installed in the chute of fixed head 257 by bearing pin 256.1.2 times of the length of the horizontal elongated slot 254 of described push rod preferably horizontal pendulum plate 255 width; Described arrangement block 251 offers the groove 2511 that can match with described sewing machine dials 1 lateral margin, and the width arranging block groove is preferably 1 times of locking pin 13 diameter on described dials.In addition, damage and noise to alleviate knife bar 12 forks caused with the power transmission collision impact of fork 22 one end of cranking arm, the special undertaking at fork 22 of the present embodiment is collided end and has been installed flexible resilient block 223 additional.
See accompanying drawing 1, during work, knife bar is cranked arm about 12 reciprocally swingings, when swing touches fork 22 one end left, namely promote fork rotary middle spindle 221 to rotate counterclockwise, thus first connecting rod 23 is promoted to the right by the slide block 222 on fork 22 other end, so the second connecting rod 24 that upper end is affixed with first connecting rod 23, lower end connects with push rod 25 one end promotes push rod 25 horizontal movement to the right, the groove making push rod end arrange block 251 pushes to sewing machine dials 1 lateral margin.
Be articulated in the garment piece in this pin section on the sewing position of dials, and sewing machine dials 1 rotates clockwise under the drive of its transmission mechanism, be positioned at garment piece sew up automatic arranging device 2 sewing mechanism below knife bar crank arm 12 drive under the garment piece on dials sewing position is sewed up.
When knife bar crank arm 12 be swung away from fork 22 one end to the right time, back-moving spring 252 resilience of push rod produce active force make push rod to left movement, drive and arrange the lateral margin that block 251 leaves dials 1, promote the second first connecting rod move right and reset simultaneously, meet knife bar crank arm 12 second time collision promote.So, back and forth constantly work.
Embodiment 2: a kind of sewing machine garment piece sews up automatic arranging device, its general structure is substantially with embodiment 1, the screw connecting adjusting bolt 241 is just provided with at the non-fixed connecting end of second connecting rod 24, adjusting bolt 241 leading section contacts with the rearward end of push rod 25, adjusting bolt 241 is provided with lock nut 242.Regulate the certain distance between second connecting rod 24 one end and push rod 25 by adjusting bolt 241 before work, make push rod end arrange block groove and insert the suitable degree of depth of sewing machine dials lateral margin, be positioned on dials sewing position to ensure that promotion garment piece is accurate to.It is more flexible, timely, convenient that this structural detail makes adjustment operate.
