According to the utility model, the mechanism is simple in structure, large in driving force, precise in positioning, sensitive in reaction, convenient for debugging, and high in working efficiency.

Description

The presser feet of Sewing machines lifts driving mechanism
Technical field
The utility model relates to a kind of Sewing machines, and the presser feet that is specifically related to a kind of Sewing machines lifts driving mechanism.
Background technology
Existing Sewing machines, its presser feet lifts driving mechanism and generally adopts solenoid actuated mode.Sensitive not due to electromagnet reaction, cause presser feet to lift circulation timei long, thereby make operating efficiency low.
Also there is the impulse motor of employing directly to drive, but due to impulse motor limited torque output, cause lifting of presser feet lifting mechanism unstable.In addition, if adopt impulse motor, location need be regulated by inductor, is again open cycle system, can cause motor location inaccurate, causes the phenomenon of positioning to occur.
Summary of the invention
The presser feet that technical problem to be solved in the utility model is to provide a kind of Sewing machines lifts driving mechanism, and it can realize the accurate location to presser feet frame.
For solving the problems of the technologies described above, the technical solution that the presser feet of the utility model Sewing machines lifts driving mechanism is:
Comprise that presser feet lifts servo motor, the output shaft that presser feet lifts servo motor connects presser feet and lifts the driving wheel of change gear pair, and the driven pulley that presser feet lifts change gear pair is fixedly connected with presser feet and lifts cam; Presser feet lifts cam and presser feet lifts roller composition cam mechanism, presser feet lifts one end that roller is fixedly connected with presser feet and lifts crank, the other end that presser feet lifts crank connects one end that presser feet lifts connecting rod, presser feet lifts one end of the other end connection presser bar linking arm of connecting rod, and the other end of presser bar linking arm connects presser feet frame.
Described presser feet lifts servo motor and lifts change gear subband dynamic pressure pin through presser feet and lift cam rotation, presser feet lift cam by presser feet lift roller drive presser feet lift crank-motion, realizing to rotatablely move is converted into rectilinear motion, presser feet lifts crank and lifts the motion of connecting rod drive presser bar linking arm by presser feet, presser bar linking arm drives presser feet frame to move up and down, thereby drives presser feet frame to rise or decline.
It is forward motor, reverse motor or rotating motor that described presser feet lifts servo motor.
It is symmetrical structure that described presser feet lifts cam.
The technique effect that the utility model can reach is:
The utility model is simple in structure, and driving force is large, and registration is quick on the draw, and debugging is convenient, and operating efficiency is high.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the schematic diagram that the presser feet of the utility model Sewing machines lifts driving mechanism;
Fig. 2 is partial exploded view of the present utility model.
Description of reference numerals in figure:
1 for presser feet lifts servo motor, and 2 for presser feet lifts cam,
3 for presser feet lifts change gear pair, and 4 for presser feet lifts crank,
5 for presser feet lifts connecting rod, and 6 for presser feet lifts roller,
15 is presser feet frame.
Detailed description of the invention
As shown in Figure 1 and Figure 2, the presser feet of the utility model Sewing machines lifts driving mechanism, comprise that presser feet lifts servo motor 1, the output shaft that presser feet lifts servo motor 1 connects presser feet and lifts the driving wheel of change gear pair 3, and the driven pulley that presser feet lifts change gear pair 3 is fixedly connected with presser feet and lifts cam 2; Presser feet lifts cam 2 and lifts roller 6 with presser feet and form cam mechanism, presser feet lifts one end that roller 6 is fixedly connected with presser feet and lifts crank 4, the other end that presser feet lifts crank 4 connects one end that presser feet lifts connecting rod 5, presser feet lifts one end of the other end connection presser bar linking arm of connecting rod 5, and the other end of presser bar linking arm connects presser feet frame 15;
Presser feet lifts servo motor 1 and lifts change gear secondary 3 through presser feet and drive presser feets to lift cam 2 to rotate, presser feet lifts cam 2 and lifts roller 6 by presser feet and drive presser feet to lift crank 4 to move, realizing to rotatablely move is converted into rectilinear motion, presser feet lifts crank 4 and lifts connecting rod 5 by presser feet and drive presser bar linking arm motion, presser bar linking arm drives presser feet frame 15 to move up and down, and drives presser feet frame 15 to rise or decline thereby realize before and after making.
It can be forward motor, reverse motor or rotating motor that presser feet lifts servo motor 1.
Presser feet lifts cam 2 for symmetrical structure, so that revolving force size and its irrelevant to rotation direction that cam rotation is transmitted.
Driving principle of the present utility model is as follows:
The conversion that the rotary driving force that presser feet lifts servo motor 1 lifts change gear pair 3 by presser feet strengthens, and changes the driving force to presser feet lifting mechanism into; Presser feet lifts the cam surface that roller 6 lifts cam 2 along presser feet and slides, and driving force is passed to presser feet and lift connecting rod 5, and presser feet lifts connecting rod 5 and drives presser feet frame 15 upwards to lift, thereby the presser feet completing before and after making lifts action.
