Description
Technical field
The utility model is related to a kind of embroidery machine presser foot transmission system, specifically a kind of presser feet with a word connecting rod
Transmission device.
Background technology
At present for the device for coordinating the embroidering pin on shank to be embroidered in machine head of embroidery machine, foot device is generally comprised,
Its drive mechanism of existing foot device is generally to synchronize driving by separating a connecting rod on shank transmission device, this
Its advantage of kind type of drive is simple in construction, is had the disadvantage because a set of transmission system needs to drive two devices of shank and presser feet,
Its heavier loads causes equipment noise larger, and another aspect shank and presser feet share a set of transmission system its stability for being oriented to
It is relatively poor.Certainly the technology for separately driving shank and presser feet also considers, that is, presser feet is separately through presser feet power train
System drives but machine head of embroidery machine inner space is very limited amount of in reality, it is impossible to reserved a large amount of to those skilled in the art
Space.Thereby how realize and set presser foot driving device to be those skilled in the art's research in head this small space
Object.On the other hand as an important technical background presser feet be usually be socketed shank can be as shank be pressed downwardly together
Foot press cloth, but presser feet compress its close to speed during cloth cover be can not too fast perfect condition be close to zero, too soon will be by
In the huge impulsive force of presser feet pressure surface generation and noise, and the embroidering pin of shank connection must penetrate cloth cover at a high speed, also
It is that the part that shank and presser feet two are mutually socketed must produce two kinds of speed, is exactly to be driven by above-mentioned foot device at present
Two drive systems are driven to complete two kinds of actuating speeds with shank, and the speed of presser feet is the speed and presser feet driven by shank
Device drives what the difference between reverse speed was determined, and this difference is the smaller the better in real time, in the prior art for this
It is typically difficult to control to difference, and how to control this difference is one of the problem of present invention needs solution.
Utility model content
The utility model provides a kind of relatively low presser feet with a word connecting rod of accurate, driving stabilization, noise that is oriented to and passed
Dynamic device.
A kind of presser foot driving device with a word connecting rod includes the presser feet of main shaft drives, presser feet connection shank, shank peace
Loaded on presser foot driving device on needle bar frame, is provided between main shaft and presser feet, described presser foot driving device includes connection main shaft
Cam, one word connecting rod of actuated by cams, a word connecting rod is connected with the V-arrangement connecting rod of an opening upwards, and the V-arrangement of opening upwards connects
Bar coordinates feet motion.This kind of presser foot driving device coordinates the V-arrangement bar linkage structure of opening upwards to realize presser feet by a word connecting rod
Independent transmission system, not only increases the stability of driving, and V-arrangement connecting rod be belong to delta link its in actuated by cams
Under, the amplitude that swings up and down is highly stable can to realize that differential coordinates relative to presser feet, reduce compress noise.Here differential is matched somebody with somebody
Close it and be totally different from conventional art, the existing foot-powered connecting rod of pressure is to be fixedly connected with presser feet by differential mechanism, also
It is that shank drive that presser feet is subject to and connecting rod are offset up and down by the power on differential drive to presser feet, it is this to offset
The differential of generation is curvilinear motion due to the movement velocity of shank, and the driving force that presser feet drive device is brought can not be good
This curvilinear motion of matching speed.The present invention coordinates feet motion, that is, V due to the V-arrangement connecting rod using opening upwards
Shape connecting rod and presser feet are (tradition can not be separated) that can be separated, and the V-arrangement connecting rod of opening upwards and the connection end of presser feet are in driving
During presser feet be in circular arc Track fusion, that is, the present invention presser feet driving force be also curvilinear motion can be with shank
The matching of the velocity interpolation of drive well reaches the muting function of compress with this.Here circular arc Track fusion its arc track
Determined by cam face.
In order to further improve the stability and accuracy of transmission, flank of cam is provided with track groove, track groove provided with rolling

Mounting hole on casing, the other end coordinates the mounting hole of one end in the middle of the V-arrangement connecting rod of opening upwards.This kind of mounting structure is by one
The V-arrangement connecting rod of word connecting rod and opening upwards carries out arranged in dislocation there is provided two different Support Positions, improve mounting stability and
Muting function, this mounting means solves the technology drawback of single support in conventional drive system.
Described presser feet be divided into up-down structure upper piece and bottom sheet, upper piece connection sheet for being structure as a whole between bottom sheet,
Needle bar hole of the connection sheet provided with socket shank, upper piece top is connected with presser feet sliding sleeve, presser feet sliding sleeve socket shank, presser feet sliding sleeve
With two coaxial guide functions of needle bar hole formation up-down structure, the stability run above and below presser feet is improved.Further technology
Scheme is, upper piece and bottom sheet be located at the front and rear sides of shank respectively, further improve the stability run above and below presser feet.
Connected between the V-arrangement connecting rod and presser feet of described opening upwards by presser feet sliding sleeve, presser feet sliding sleeve includes sleeve base,
Sleeve base one end connects presser feet upper piece, and the other end coordinates in the middle of the V-arrangement connecting rod of opening upwards, sleeve base provided with leading for raising up
To set, guide sleeve coordinates the stability run above and below shank, increase presser feet.
In order to improve muting function, V-arrangement connecting rod and the presser feet sliding sleeve connection end of opening upwards are provided with shock absorbing ring.
Because presser feet is driven separately through transmission system, there is annexation in the V-arrangement connecting rod of presser feet and opening upwards, thus
The V-arrangement connecting rod of opening upwards exists on horizontal space interference, needle bar frame close to shank one end relative to the needle bar frame for installing shank
The shank guide plate for avoiding above-mentioned horizontal space is installed, shank guide plate is provided with guide groove, and guide groove, which coordinates, is arranged on pin
Guide pad on bar.Interfere for horizontal space and refer to if the V-arrangement that the extension of needle bar frame transverse horizontal can encounter opening upwards connects
Bar, this is also to cause that the technical problem that presser feet is operated alone can not be realized at present.The utility model on needle bar frame by being provided with
The shank guide plate of above-mentioned horizontal space is avoided, the guiding for shank is realized by guide pad, above-mentioned technical problem is solved.Institute
The shank guide plate stated is separated from each other with presser feet sliding sleeve, and shank guide plate, which is placed in above presser feet sliding sleeve, forms two sets of independent guiding systems
System, the respectively guiding of shank and the guiding of presser feet, improve guiding accuracy.In order to increase the stability and convenient reset pin of motion
Bar periphery is cased with spring, and spring is located between presser feet and guide pad.
The utility model coordinates V-arrangement bar linkage structure to realize the transmission system of presser feet independence by a word connecting rod, not only improves
The stability of driving, and it is good to coordinate the separable driving for carrying out arc track formula to realize between V-arrangement connecting rod and presser feet
Differential coordinates, and reduces presser feet compress noise.
