It is connected with three connecting rods 103 and drive link 108, drive link 108 is parallel with needle bar frame 105 and needle bar frame can be driven living about 105
Dynamic, needle bar frame 105 is provided with upper limit position block 106 and lower position block 107, and both drive blocks 109 on drive link 108 drive,
The bottom of needle bar frame 105 is provided with carving hole knife 110 and some embroidery needles；Cam pack 102 is driven to revolve when rotary shaft 101 is rotated and reverse
Turn, and then carving hole knife 110 and the up and down carry out embroidering work of embroidery needle are driven by small rod 104 and drive link 108.It is existing
The installation method of embroidery machine cam pack is：Sleeve pipe cam pack crank close to presser foot driving cam side is lengthened, and allows pressure
Pin driving cam is fastened on above sleeve pipe, and defect is to install inconvenience, and stability is bad.
Utility model content
The purpose of this utility model is to provide a kind of embroidery machine cam pack mounting structure, to improve its install convenient
Property and job stability.
In order to solve the above technical problems, the utility model provides a kind of embroidery machine cam pack mounting structure, the cam set
Part include cam pack base, cam pack swing rod, cam pack bearing and cam pack crank, the cam pack swing rod and
The cam pack crank is connected as a single entity and by the cam pack bearings in the cam pack base, the cam set
The presser foot driving cam of part crank and embroidery machine is fixed independently to the upper axle of embroidery machine.
More preferably, the cam pack crank is fixed on the upper axle by cam fastening lasso.
More preferably, the presser foot driving cam is fixed on the upper axle by presser foot driving cam seat.
More preferably, the tail end of the upper axle sets presser foot driving cam seat adapter sleeve, and the presser foot driving cam fixes peace
After presser foot driving cam seat, it is one that presser foot driving cam seat and the presser foot driving cam adapter sleeve, which are fastened,
Body so that the presser foot driving cam is fixedly mounted on the upper axle.
More preferably, the upper axle is supported in embroidery machine spindle drum by upper axle bearing and positioned with shaft-cup and snap ring.
Compared with prior art, cam pack crank and presser foot driving cam are independently fastened directly to by the utility model
Upper axle, thus install convenient and job stability can be improved, specifically：Both (1) fasten one by one, it is easy for installation；(2)
Presser foot driving cam is independently fastened, and is reduced and is fastened the pressure of lasso to the vibration influence and cam pack of cam pack during dynamic turn
The possibility that axle walks in power, reduction, makes whole embroidery process more stablize；(3) contact of presser foot driving cam fastening is increased
Face so that presser foot driving cam stability during running at high speed is substantially improved.
Brief description of the drawings
Fig. 1 is existing embroidery machine cam pack mounting structure.
Fig. 2 is the utility model embroidery machine cam pack mounting structure.
Embodiment
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and tool
Body embodiment is described in detail.
It is the utility model embroidery machine cam pack mounting structure referring to Fig. 2, it shows machine head of embroidery machine component cam group
The relative position relation of part (being commonly called as cam family of four, detailed construction refers to known prior art) and presser foot driving cam.
The cam pack includes cam pack base 3.1, cam pack swing rod 3.2, cam pack bearing 3.3 and cam pack crank
3.4, cam pack swing rod 3.2 and cam pack crank 3.4 are connected as a single entity and are supported in cam pack by cam pack bearing 3.3
On base 3.1, cam family of four is thus constituted.The mounting structure of the cam pack is：Cam pack crank 3.4 is fastened by cam
Lasso 8 is fixed on axle (embroidery machine main shaft) 9, on this axle 9 embroidery machine spindle drum 7 is supported in by upper axle bearing 5 and by shaft-cup 5 and
Snap ring 6 is positioned, and presser foot driving cam 1 is fixed on the tail end of upper axle 9 by presser foot driving cam seat 1.2.Specifically, upper axle
9 tail end sets presser foot driving cam seat adapter sleeve 3, and presser foot driving cam 1, which is fixed, to be loaded on after presser foot driving cam seat 1.2, will
Presser foot driving cam seat 1.2 is fastened with presser foot driving cam adapter sleeve 2 with screw, so that presser foot driving cam 1 fixes peace
It is attached on axle 9.
In the embodiment, cam pack crank 3.4 is fastened into lasso 8 by cam and is anchored on upper axle 9, presser foot driving cam
1 is also individually fastened on axle 9；Presser feet driven because both are individually directly fastened on upper axle 9, rather than as prior art
Moving cam 1 is installed on cam pack crank 3.4 on the sleeve pipe of the side of presser foot driving cam 1, thus can drive presser feet convex
The external diameter of wheel seat adapter sleeve 3 does small, and take-up swing rod 10 is will not interfere with when it is towards right side.Advantage of this is that：(1) each part by
Individual fastening, it is easy for installation；(2) the independent fastening of presser foot driving cam 1, reduces the vibrations shadow to cam pack during dynamic turn
Ring, and decrease the pressure that cam pack fastens lasso 8, the possibility that axle 9 walks greatly reduces, make whole thorn
Embroidery process is more stablized；(3) contact surface of the fastening of presser foot driving cam 1 is increased so that presser foot driving cam 1 is running at high speed
During stability be substantially improved.
Although the utility model is disclosed as above with preferred embodiment, its be not for limiting the utility model, it is any
Those skilled in the art are not being departed from spirit and scope of the present utility model, can make possible variation and modification, because
The scope that this protection domain of the present utility model should be defined by the utility model claim is defined.
