Abstract
The utility model relates to a mechanism for adjusting instantaneously the interacting volume of a needle foot of a sewer, which comprises an adjusting crank 1, a hinge shaft 5 that can slide up and down in the central groove of the adjusting crank, a needle foot swing shaft 16 connecting the adjusting crank 1 and partial sewer body 17, and an eccentric link rod 18. The utility model is characterized in that, at outer side of the hinge shaft 5, a pneumatic adjusting mechanism is provided, which can manipulate the movement of the hinge shaft 5 and comprises a cylinder 10 and an adjustable nut 19. The lower part of the cylinder 10 is connected with a cylinder joint 4 with a slot, the slot at lower part of the cylinder joint 4 is provided with a shaft sleeve 3. The outside of the shaft sleeve 3 is looped with an eccentric link rod 18 whose side projects outside. The hinge shaft 5 passes in the shaft sleeve 3. The upper part of the main body of the cylinder 10 is connected with an L-like mounting plate 13 that is located at partial sewer body 17 through an angular cylinder seat fixed with the cylinder body, an angular cylinder seat bolt 15, another swinging plate 12 and a bolt shaft 14. In this way, the mechanism for adjusting instantaneously the interacting volume of a needle foot is constituted.
Description
Technical field
The utility model relates to a kind of Sewing machines moment adjusting pressure foot interactive amount mechanism, belongs to the foot device of sewing machine.
Background technology
The tradition sewing-machine foot is measured governor motion alternately and is: see accompanying drawing 2 for details.
By unclamping the upper-lower position of nut 8 manual setting hinge axis 3 in regulating crank 4, fastening nut 8 again after similar, tighten screw 7 fixing presser foot swinging axles 16 simultaneously, swinging axle 16 penetrates sewing machine body 17 backs and drives the presser feet feeding, driving power is to go up axle to rotate drive eccentric ratio 8, realizes that inside and outside presser feet is mutual.
This regulative mode is owing to adopted manual adjustment, upper-lower position is transferred inaccurately unavoidably, all must unclamp nut 8 at every turn and remake fine setting, part mounting or dismounting frequency is increased, easily cause parts depreciation, bring unnecessary trouble to operating personnel, waste time and energy, influence production efficiency. most importantly when making the sewing of uneven thickness, because mutual amount mixes up, cause presser feet to run into just climbing difficulty of thick place, even running stop.
The utility model content
This Sewing machines moment adjusting pressure foot interactive amount mechanism, form by pads swing axis 16 and the eccentric ratio 18 of regulating crank 1, the hinge axis 5 that can in regulating crank central channel, slide up and down, connection adjusting crank 1 and part sewing machine body 17, it is characterized in that: the gas control governor motion that can control its motion and be made up of cylinder 10 and adjustable nut 19 is set in the groove outer end of described hinge axis 5; Described cylinder 10, its underpart are connecting trough of belt implication cylinder joint 4, and these cylinder joint 4 bottom notches are being provided with axle sleeve 3, and the outside of axle sleeve 3 is being nested with the overhanging eccentric ratio of side direction 18, this axle sleeve 3 placing hinge axis 5; The main body top of described cylinder 10 is by angle cylinder seat, the angle cylinder seat screw 15 affixed with body, and an other oscillating deck 12, screw axis 14 be connected with L type installing plate 13 on being located at part sewing machine body 17, forms moment thus and regulate pressure foot interactive amount mechanism.
This Sewing machines moment adjusting pressure foot interactive amount mechanism according to above technical scheme design, because adopting the cylinder adjustment measures alternately, only need turn adjustable nut 10 and carry out the upper-lower position change, thereby do not exist parts depreciation and repeatedly mounting or dismounting, and also be that cylinder is fixed after the adjustment satisfaction, be difficult for positioning, make the machine stitching effect further improve, time saving and energy saving.Most importantly in the time of can making presser feet run into the sewing of uneven thickness, cylinder can be adjusted mutual amount moment, makes the sewing of uneven thickness under non-stop-machine state smoothly, and is very convenient and practical.
Description of drawings
Accompanying drawing 1 is the utility model structural representation (three-dimensional exploded view)
Accompanying drawing 2 is old-fashioned adjusting pressure foot interactive amount mechanism structural representation.
Among the figure: 1, regulate crank 2, crank cover plate 3, axle sleeve screw 4, cylinder joint 5, hinge axis 6, screw 7, crank screw 8, nut 9, pad 10, cylinder 11, button 12, oscillating deck 13, L type installing plate 14, screw axis 15, angle cylinder seat screw 16, pads swing axis 17, part sewing machine body 18, eccentric ratio 19, adjustable nut
The specific embodiment
This Sewing machines moment adjusting pressure foot interactive amount mechanism as shown in Figure 1, it is a kind of inventive improvements to existing congenerous device, this improved dominant ideas are to increase the adjustable cylinder of stroke, improve traditional adjusting crank, adopt the adjustable nut on the cylinder to regulate mutual amount, and light fixed position.
The concrete structure of this gas control governor motion is as follows: be that the gas control governor motion that can control its motion and be made up of cylinder 10 and adjustable nut 19 is set in the groove outer end of the hinge axis 5 of original device.Described cylinder 10, its underpart are connecting trough of belt implication cylinder joint 4, and these cylinder joint 4 bottom notches are being provided with axle sleeve 3, and the outside of axle sleeve 3 is being nested with the overhanging eccentric ratio of side direction 18, this axle sleeve 3 placing hinge axis 5; The main body top of described cylinder 10 is by angle cylinder seat, the angle cylinder seat screw 15 affixed with body, and an other oscillating deck 12, screw axis 14 be connected with L type installing plate 13 on being located at part sewing machine body 17, forms moment thus and regulate pressure foot interactive amount mechanism.
Concrete mechanism decomposes as follows: four screws 6 of novel adjusting crank 1 and crank cover plate 2 usefulness are connected, hinge axis 5 is slided up and down to be used for adjusting the position in the chute of regulating crank 1, hinge axis 5 passes axle sleeve 3 then, reinstall cylinder joint 4 and eccentric ratio 18, tighten fixing with nut 8 and pad 9 to transmit axle power.Cylinder 10 with fixedly connected with oscillating deck 12 by angle cylinder seat screw 15 again after cylinder joint 4 is connected.L type installing plate 13 is fixed on the sewing machine body (part) 17 by two screws 7, and by screw axis 14, pad 9 and nut 8 are connected L type installing plate 13 with oscillating deck 12 at last, and cylinder also can be with eccentric ratio 18 swings when being implemented in the Sewing machines running.Adjustable nut 19 on the cylinder 10 can carry out the stroke adjustment, but button 11 moment control cylinder 10 is flexible.
This structure only need turn adjustable nut 10 and carry out the upper-lower position change owing to adopt the cylinder adjustment to measure alternately, thereby does not have parts depreciation and repeatedly mounting or dismounting, and also be that cylinder is fixed after the adjustment satisfaction, be difficult for positioning, make the machine stitching effect further improve, time saving and energy saving.Most importantly in the time of can making presser feet run into the sewing of uneven thickness, cylinder can be adjusted mutual amount moment, makes the sewing of uneven thickness under non-stop-machine state smoothly, and is very convenient and practical.
