In a specific embodiment, sewing machine provided by the utility model includes head connection component on the whole
1 and head 2, the other structures of certain sewing machine are since, without direct correlation, the utility model no longer refers to the utility model.
Head 2 is main equipment, it is mounted by head connection component 1.
Head connection component 1 realizes the mounting with casing by fuselage mounting plate 61, therefore fuselage mounting plate 61 carries
All multi-parts.
Motor 11 is installed on fuselage mounting plate 61, motor 11 can be rotating electric machine, can also with hydraulic motor etc. its
His power part.Motor 11 is vertically arranged, i.e., its output shaft is vertically arranged.Certainly, it is so-called it is vertically arranged be and laterally set
Opposite concept is set, some special value should be utterly defined in by being not meant as its vertical angle.
The output shaft of motor 11 is also equipped with pinion gear 14, so as to drive pinion gear 14 to rotate.Pinion gear 14 and branch
Pinion shaft 16 can be set between seat 41.
Support 41 is also equipped on fuselage mounting plate 61, support 41 can be relative to fuselage mounting plate 61 in vertical direction
Upper opposite sliding.
The basic function of support 41 be support dependency structure, though therefore need not be strict with, it generally answers level to set
It sets, and therefore the substantially vertical setting of fuselage mounting plate 61 considers for reasonable integral structure, can be arranged therebetween
The side of left side bracket 42 and right side bracket 44, left side bracket 42 and right side bracket 44 respectively with the left and right two of fuselage mounting plate 61
Side slides vertically connection, and the bottom edge of left side bracket 42 and right side bracket 44 is respectively fixedly connected with the left and right sides of support 41.
In addition, above-mentioned be slidably connected itself belongs to mature technology, therefore both above-mentioned mode being slidably connected can join
Examine the prior art；But it can also be realized according to following more preferably mode:
For example, linear guide 51, two linear guides can vertically be fixedly mounted in the left and right sides of fuselage mounting plate 61
51 match with corresponding sliding block 52, and two sliding blocks 52 further fix connection bracket mounting base 53, the installation of two brackets
Seat 53 is connect with the side of the side of left side bracket 42 and right side bracket 44 respectively in turn.
Head 2 is carried by support 41, and can be rotated relative to support 41；The periphery of head 2 is further set with
The gear wheel 33 of synchronous rotation, gear wheel 33 are engaged with pinion gear 14.
Lifting drive component, the bottom of the elevating lever 24 of the lifting drive component are also equipped on fuselage mounting plate 61
It is connected with support 41.The lifting drive component is equally vertically arranged namely elevating lever 24 is general vertical setting, Neng Gougai
Become vertical position of the support 41 relative to fuselage mounting plate 61.
Pinion gear 14 in the utility model is particularly configured to long tooth face gear, it is rationally arranged in conjunction with specifically used occasion
Length and position range, so that gear wheel 33 with pinion gear 14 is always maintained at the state being meshed in lifting travel.
Sewing machine provided by the utility model, head can be rotated relative to support driven by a moto,
Therefore can when sewing backstitches direction rotating head component, make the mutual alignment of eedle and suture be always held at along seam when
State improves the quality of sewing so as to avoid backward stitch is generated.
At the same time, when encountering sewing is bulge-structure, lifting drive component can be passed through at the end of every section of sewing
Head is promoted, to realize the evacuation to sewing.
More importantly pinion gear is long tooth face gear, gear wheel engages shape with pinion gear holding in lifting travel
State；As such, it is desirable to which the relatively simple for structure of lifting drive component raising, number of components are less, the weight of lifting were both alleviated, had subtracted
The specification and cost of small lifting driving, meanwhile, motor and lifting drive component design side by side also can make the structure of equipment more
Step up to gather, carries out rational deployment on the whole convenient for each component.
Furthermore, it is possible to do some other improvement to sewing machine provided by the utility model.
For example, the lifting drive component can be cylinder 21, cylinder rod is vertically arranged.Certain lifting drive component
It can also be other common lifting parts such as oil cylinder, screw rod.
Cylinder 21 can be fixedly connected by cylinder mounting plate 22 with fuselage mounting plate 61；Certainly the two can also directly connect
It connects.
The extension end of cylinder 21 can directly be connect with elevating lever 24, but can also pass through floating junction 23 and elevating lever 24
Connection, advantageously reduces installation error in this way.
The output shaft of rotating electric machine can directly be connect with pinion gear 14, can also pass through retarder 12 and shaft coupling 13
It is connect with pinion gear 14.Retarder 12 may be mounted on retarder support 15.
Arrangement above can advanced optimize the structure of equipment, realize stable work shape in simple structure
State.
Referring to FIG. 4, Fig. 4 is the schematic cross-sectional view of Fig. 1 bottom bracket axle mounting means.
As previously mentioned, head 2 is carried by support 41, and can be rotated relative to support 41.It can be by with lower section
The connection of formula realization head 2 and support 41.
The rotation set 34 being rotatablely connected with support 41 is set, and head 2 is mounted on rotation set 34 by the setting of 34 general vertical of rotation set
Gear wheel 33 is fixedly mounted on the top peripheral of rotation set 34 by bottom.
Support flange 45 can also be fixedly mounted in support 41, so that rotation set 34 be made to rotate by bearing 46 and support flange 45
Connection, and then realize rotation connection of the rotation set 34 relative to support 41.
Head connecting flange 35 can be set in the bottom of rotation set 34, and head 2 can pass through head connecting flange 35 and rotation set
34 are fixedly connected.
The top of rotation set 34 can also install slip ring 31, specifically, rotation set 34 can be fixedly connected with slip-ring rotor 311,
Slip-ring rotor 311 and rotation set 34 are coaxially disposed；The top of slip-ring rotor 311 is further rotatably connected to same coaxially setting
Slip ring stator 312.
Slip ring stator 312 is fixedly connected by slip ring check plate 43 with left side bracket 42 or right side bracket 44, certainly
Can be with both and meanwhile be fixedly connected；So as to improve the operation stability of equipment.
The setting of the above rotation set 34 and its related accessory, the rotary course of head 2 can be made by simple structure
It is more reliable and stable.
Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other
The difference of embodiment, the same or similar parts in each embodiment may refer to each other.
Sewing machine provided by the utility model is described in detail above.Specific case used herein is to this
The principle and embodiment of utility model is expounded, the above embodiments are only used to help understand the utility model
Method and its core concept.It should be pointed out that for those skilled in the art, it is practical new not departing from this
