Description
Technical field:
The utility model belongs to sewing machine technique field, refers in particular to the differential of a kind of Sewing machines and compares governor motion.
Background technology:
Under normal circumstances, feed dog is the same with the stroke of differential tooth to Sewing machines, is that is synchronous.But, at some special occasions, during as made thin material, need by regulating the differential stroke than controlling differential tooth different to realize different effects of making, as: the stroke of differential tooth is become large, then cloth can be strutted in the process of making; The stroke of differential tooth is diminished, then cloth can be sewed a kind of effect of fold.Existing differential governor motion is regulated in casing outside by the transmission mechanism of complexity.Due to the complexity of transmission mechanism, too increase difficulty to casing processing and assembling, casing repair rate is high, thus reduces production efficiency.Moreover because of consume part more, production cost also increases thereupon.
Summary of the invention:
It is simple, convenient that the purpose of this utility model is to provide a kind of adjustment, and the differential of Sewing machines that structure simplifies compares governor motion.
The utility model is achieved in that
The differential of a kind of Sewing machines compares governor motion, comprise differential swing connecting bar, one end of differential swing connecting bar is installed on cloth pushing shaft, on the other end and is provided with arc chute, one end of connecting pin is arranged in arc chute, the other end is connected with differential connecting rod, the other end of differential connecting rod is connected with differential retainer, regulates the position of connecting pin in arc chute to realize the adjustment of differential ratio.
In technique scheme, one end of described connecting pin is embedded in arc chute also with screw and washer locking.
In technique scheme, be provided with lining in another stomidium of described differential connecting rod, differential connecting rod and lining are connected on differential crank by screw.
In technique scheme, the other end of described differential connecting rod is connected with differential crank, and differential crank is fixed on differential retainer.
The advantage that the utility model is given prominence to compared to existing technology is:
1, the utility model realizes the adjustment of differential ratio by toggle, toggle is arranged on casing internal, only need have gentle hands gently to break head left cover screwdriver into two with one's hands to turn on screw and move up and down the differential ratio that just can regulate machine easily, decrease a large amount of number of parts, structure simplifies, both facilitate the assembly difficulty that casing processing again reduces machine, improve operating efficiency;
2, design of part of the present utility model is fairly simple, can enhance productivity to a great extent and reduce production cost, improves the stability of structure.
Accompanying drawing illustrates:
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is the structural representation of the utility model crank connecting link;
Fig. 3 is mechanism kinematic of the present utility model.
Detailed description of the invention:
With specific embodiment, the utility model is further described below, see Fig. 1-3:
The differential of a kind of Sewing machines compares governor motion, comprise differential swing connecting bar 1, one end of differential swing connecting bar 1 is installed on cloth pushing shaft 3, on the other end by screw 2 and is provided with arc chute 4, one end of connecting pin 5 to be arranged in arc chute 4 and locked by screw 6 and packing ring 7, the other end is sleeved on outside differential connecting rod 8, differential connecting rod 8 can rotate around connecting pin 5.The other end of differential connecting rod 8 is connected with differential crank 9, and differential crank 9 is fixed by screws on differential retainer 10, and differential retainer 10 is provided with differential tooth 11.The position of connecting pin 5 in arc chute 4 is regulated to realize the adjustment of differential ratio.
Be provided with lining in another stomidium of described differential connecting rod 8, differential connecting rod 8 and lining are connected on differential crank 9 by screw 12.
The adjustment of differential ratio of the present utility model is realized by toggle, formed, and differential linkage is arranged on casing internal by parts such as differential goods of furniture for display rather than for use connecting rod 1, differential connecting rods 8.During adjustment, gently break with have gentle hands the screw 6 that locking connecting pin 5 turned on by head left cover screwdriver into two with one's hands, increase differential ratio by up mobile for connecting pin 5, move down and reduce differential ratio, simple to operation.
Principles of Regulation are:
Up move in the arc chute 4 of connecting pin 5 in differential swing connecting bar 1, when cloth pushing shaft 3 pendulum angle is constant, the distance increased between connecting pin 5 and cloth pushing shaft 3 just can increase the amplitude of oscillation of connecting pin 5, because the other end of differential connecting rod 8 is connected with differential crank 9, therefore the movement travel of differential crank 9 becomes large, within the identical time, the stroke of differential tooth 11 is greater than work feed tooth 13, differential than increasing;
Otherwise then the distance reduced between connecting pin 5 and cloth pushing shaft 3 just reduces the amplitude of oscillation of connecting pin 5, and the movement travel of differential crank 9 diminishes, and within the identical time, the stroke of differential tooth 11 is less than work feed tooth 13, differential than reducing.
Above-described embodiment is only one of preferred embodiment of the present utility model; not limit practical range of the present utility model with this; therefore: all equivalence changes done according to shape of the present utility model, structure, principle, all should be covered by within protection domain of the present utility model.
