Abstract
The utility model relates to a round-head buttonholing machine for sewing buttonholes of clothes, and provides a computer round-head buttonholing machine needle swaying mechanism. A needle swaying protruding wheel is in driving connection with a protruding wheel fork, the protruding wheel fork is connected with the upper end of a connecting pole in hinged mode, the lower end of the connecting pole is connected with a needle swaying rod in hinged mode, the needle swaying rod is composed of an adjusting rod and a connecting rod, an arc-shaped groove is arranged on the connecting rod, and the circle center of the arc-shaped groove is the hinge center of the protruding wheel fork and the upper end of the connection pole. A screw shaft, a sliding block and a bearing are mounted at the lower end of the connecting pole, the sliding block is placed into the arc-shaped groove, and the connecting pole is connected with the adjusting rod in hinged mode through the screw shaft, the sliding block and the bearing. According to the computer round-head buttonholing machine needle swaying mechanism, a swaying rod is designed into an arc-shaped rod, wherein the radius of the arc-shaped rod is the length of the adjusting rod, and the circle center of the arc-shaped rod is the hinge point at the upper end of the connecting pole. When the size of needle swaying range needs to be adjusted, a user just needs to unscrew a connecting nut between the adjusting rod and the swaying rod, the length of the swaying rod is adjusted, and then the connecting nut is screwed to fasten the adjusting rod and the swaying rod.
Description
Technical field
The utility model relates to Sewing machines, particularly the eyelet buttonhole sewing machine of clothes seam buttonhole sewing.
Background technology
The needle tracking of Eye button hole such as Fig. 1, the length of b is commonly referred to the balancing point width of cloth, the E line is the interior pin position of balancing point, according to earlier, after operate on (cutting buttonhole), the requirement of interior pin position is different.The balancing point width of cloth of traditional Eye button hole lockstitch button holder all must be reorientated in adjusting hour hands position, especially interior pin position, and this makes operation, and some is loaded down with trivial details.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned not enough problem, and a kind of computer eyelet buttonhole sewing machine needle vibrating mechanism is provided, and is simple in structure, after having adjusted the balancing point width of cloth, need not reorientate, simple to operate.
The utility model for realizing the technical scheme that above-mentioned purpose adopted is: computer eyelet buttonhole sewing machine needle vibrating mechanism; The balancing point cam drive connects the cam fork, and the cam fork is hinged with small end, and connecting rod lower end and balancing point swing arm are hinged; The balancing point swing arm is made up of adjusting lever and connecting rod; Offer an arc groove on the connecting rod, arc groove is the center of circle with the hinged center of cam fork and small end, and spiral shell axle, slide block and bearing are equipped with in the connecting rod lower end; Slide block places in the arc groove, and connecting rod is hinged through spiral shell axle, slide block and bearing and adjusting rod.
Said connecting rod termination connects fork, and articulated articular lamella on the fork, articular lamella are fixed on the balancing point slide block, and shank is arranged in the balancing point slide block, above the balancing point slide block skewed slot is arranged, and overlaps on the shank by bearing hinge connection on holder.
Said bearing adopts ball joint bearing.
The utility model is with the swing arm bar in the computer eyelet buttonhole sewing machine needle vibrating mechanism; Being designed to regulate length of connecting rod is radius; The upper end pin joint of connecting rod is the bow in the center of circle, when needs are regulated the balancing point width of cloth big or small, as long as unclamp the attaching nut who regulates between connecting rod and the swing arm bar; The length or the weak point of adjustment swing arm bar, clamp nut just can be realized again.

Fig. 2 is the utility model structural representation.
Fig. 3 is the utility model balancing point slide block structure sketch map.
Fig. 4 is the utility model balancing point width of cloth guiding mechanism structural representation.
The specific embodiment:
Computer eyelet buttonhole sewing machine needle vibrating mechanism as shown in Figure 2, balancing point cam drive connect the cam fork, and the cam fork is hinged with small end; Connecting rod lower end and balancing point swing arm are hinged, and the balancing point swing arm is made up of adjusting lever and connecting rod, offer an arc groove on the connecting rod; Arc groove is the center of circle with the hinged center of cam fork and small end; Spiral shell axle, slide block and ball joint bearing are equipped with in the connecting rod lower end, and slide block places in the arc groove, and connecting rod is hinged through spiral shell axle, slide block and ball joint bearing and adjusting rod.Said connecting rod termination connects fork, and articulated articular lamella on the fork, articular lamella are fixed on the balancing point slide block, and shank is arranged in the balancing point slide block, above the balancing point slide block skewed slot is arranged, and cover is articulated on the holder by ball joint bearing on the shank.
Balancing point cam 1 is by the direction as shown rotation, and actuating cam fork 2 moves up and down along guide post 3, and 4 pairs of cams of baffle ring play the axial location effect.The lower end of cam fork 2 is with spiral shell axle 5 and ball joint bearing 6 articulated connecting rods 7, and the other end of connecting rod 7 is hinged on the balancing point fork by spiral shell axle 8 and slide block 9, ball joint bearing 10, and the balancing point fork is made up of two parts---connecting rod 11 and adjusting rod 12 (fastening) by trip bolt 13; The balancing point fork is articulated on the N axle; Unclamp two trip bolts 13, regulate connecting rod 11 and adjusting lever 12, can find balancing point initial point (interior pin position); And during the adjustment balancing point width of cloth big or small, the balancing point fork can not swung., cam 1 shift fork 14 of end is moved up and down when rotating through cam fork 2, connecting rod 7 and balancing point fork; Articular lamella 21 on the shift fork drives balancing point slide block 15 and moves up and down; Above the balancing point slide block 15 as shown in Figure 3 skewed slot H is arranged, under the effect of locating piece 16, moving up and down along skewed slot of balancing point slide block also has horizontal moving; Cover 18 is articulated on the holder 20 by ball joint bearing 19 on the shank; Shank 17 is arranged in slide block, with the central cross swing of slide block 15 around ball joint bearing 19, has just formed the balancing point width of cloth.
The size of the balancing point width of cloth can be regulated as required; As shown in Figure 4; When unclamping spiral shell axle 8 and slide block 9, among the arc groove L on adjusting rod 12 during moving slider 9, the arc groove L on the adjusting rod 12 is that the upper end hinge M with connecting rod 7 is (under the above-mentioned adjusted prerequisite) in the center of circle; Therefore adjusting rod 12 and connecting rod 11 can not swung, and the interior pin position of balancing point can not change.
Usually the balancing point adjustment is on interior pin position, in initial adjustment, during the pin position, unclamps two trip bolts 13; Adjust connecting rod 11 on request in N reaches behind the pin position; Around N adjustment adjusting rod 12, arc groove L center is overlapped with the upper end pin joint M of connecting rod 7, promptly adjusting rod is motionless during moving slider 9; At this moment fastening two screws 13 just do not need to unclamp this two screws again during the adjustment balancing point width of cloth.
