The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
As shown in Figure 3; The Sewing machines syringe needle servicing unit of the utility model; Comprise a rigidity or elasticity compress frame 7, be respectively equipped with tensioning mechanism a and the tensioning mechanism b that is symmetrical distribution about two at 7 liang of abutting ends of compress frame, tensioning mechanism a links to each other through power transmission shaft 4 with tensioning mechanism b; Power transmission shaft 4 is provided with action bars 10, and action bars 10 is connected on the power transmission shaft 4 through steady pin 11; Tensioning mechanism a and tensioning mechanism b run through two earholes 18 respectively and are connected one and are connected seat board 3 with convex that Sewing machines top board projection 17 matches; 7 liang of abutting ends of compress frame are respectively along the 7 S-type distributions of compress frame.Convex connects seat board 3 structures and sewing machine table top board projection 17 structures are complementary, and connects seat board 3 and links to each other with sewing machine table top board projection 17 through attachment screw 12.
Combine shown in Figure 5ly like Fig. 4, tensioning mechanism a (tensioning mechanism b structure is oppositely arranged with tensioning mechanism a) comprises the driving member 6 that links to each other with the S type termination of compress frame 7, and driving member 6 is that an end is established indent, the other end and established the metalwork that pin-and-hole, stage casing are established spring steady pin 8; It is coupled that the rigidity of the S type termination of compress frame 7 or elastomer are compressed into driving member 6 indents; Power transmission shaft 4 runs through in the pin-and-hole of driving member 6 into and is connected with it; Driving member 6 stage casing spring steady pins 8 articulate a back-moving spring 9; Back-moving spring 9 other ends are fixed on through pin and connect on the seat board 3, and have certain tightening force, can guarantee trade mark 16 is compressed (seeing shown in Figure 4) and compress frame 7 pull-ups (seeing shown in Figure 6).Power transmission shaft 4 is fixed on through earhole 18 and connects on the seat board 3.
Driving member 6 is fixed on the power transmission shaft 4 by steady pin 5, and power transmission shaft 4 is that sky is enclosed within two earholes that connect seat board 3, allows to rotate with driving member 6, can not move.Two driving members 6 are simultaneously with power transmission shaft about 4 location.
Further specify the operation principle of the utility model below through Fig. 7-Fig. 9.
Compress frame 7 usefulness of the utility model have certain rigidity and elasticity bronze wire or guiding principle silk to bend, and shape is fixed with trade mark shape size, can be square also can circular, polygon, be principle with not overslaugh sewing.Is clamped in the indent of driving member 6 the tooled joint object 16 (trade mark) of threading in the framework of compress frame 7 location in the middle of its two ends S type shape.
As shown in Figure 7, make sewing object 16 when (trade mark) at needs, the connection seat board 3 of convex structure is connected with top board projection 17 contrapositions of sewing machine table through attachment screw 12.Pull action bars 10 then; The compress frame 7 that power transmission shaft 4 anglecs of rotation adjustment driving member 6 is connected lifts; The object 16 (trade mark) of will sewing places to sew cloth needs the position of location, and the compress frame 7 that connects through action bars 10 adjustment power transmission shafts 4 drive driving members 6 again places horizontal impaction state; Compress frame 7 levels are pressed on the sewing object 16 (trade mark); Spring steady pin 8 back-moving springs 9 in driving member 6 stage casings; Driving member 6 is positioned at top board 13 top board projection 17 both sides groove in; Guaranteed that driving member 6 can freely rotate with respect to power transmission shaft 4, below and back-moving spring 9 that spring steady pin 8 is in turning cylinder 4 place downward-sloping position, see shown in Figure 8.Back-moving spring 9 pulling force make driving member 6 that counter-clockwise rotation trend arranged below turning cylinder 4, drive compress frame 7 object 16 (trade mark) of will sewing and are pressed on and sew on sewing cloth.
After making sewing object 16 (trade mark) make, Fig. 9 is the diagrammatic sketch with the pull-up of compress frame, pulls action bars 10; The compress frame 7 that power transmission shaft 4 anglecs of rotation adjustment driving member 6 is connected is raised up to the upright position; The spring steady pin 8 in driving member 6 stage casings forwards power transmission shaft 4 tops to and back-moving spring 9 becomes the position that is inclined upwardly, and the back-moving spring pulling force makes driving member 6 clockwise rotate trend, and driving member 6 is pulled up supreme skewed; Up to control stick 10 be connected seat board 3 contact till; So far, take out sewn object, accomplish course of work of the utility model.
The utility model need be provided with a sewing machine table backing plate 2 (shown in Figure 8) according to the thin degree of being made sewing object 16 (trade mark) between top board 13 and the utility model connection seat board 3 when making sewing object 16 (trade mark).When sewing object 16 (trade mark) is relatively thinner, need not pad and establish sewing machine table backing plate 2; When sewing object 16 (trade mark) is thicker; Need establish the sewing machine table backing plate 2 of different model (this model is set by the utility model as required) according to the thin and thick pad of sewing object 16 (trade mark), so that compress frame 7 just in time is pressed on the sewing object 16 (trade mark).
Further, the driving member 6 of the utility model or design different length model is produced the utility model servicing unit of different model, just can take the driving member 6 of the longer model of length for the sewing object 16 (trade mark) that relatively approaches; Take the driving member 6 of the shorter model of length to be installed on the power transmission shaft 4 with bigger compress frames 7 for thicker big sewing object 16 (trade mark).As long as, just can realize the sewing of different thin and thick trade marks through changing the utility model of different model.
