Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Core of the present invention is to provide a kind of sewing machine, and quality of not only sewing is obviously improved, and the structure letter of equipment
List, specification is small, use cost is low, runs relatively reliable.
Fig. 1-Fig. 3 is please referred to, Fig. 1 is whole for a kind of upper head system of the provided sewing machine of specific embodiment of the present invention
Body structural schematic diagram；Fig. 2 is the stereoscopic schematic diagram of head connection component in Fig. 1；Fig. 3 is the section view of Fig. 1 bottom bracket axle mounting means
Schematic diagram.
In a specific embodiment, sewing machine provided by the present invention includes 1 He of head connection component on the whole
Head 2, the other structures of certain sewing machine are since, without direct correlation, the present invention no longer refers to the present invention.
Head 2 is main equipment, it is mounted by head connection component 1.Head connection component 1 passes through installation mainboard 33
It is directly realized by the mounting with casing, the mounting with casing can also be realized by installation mainboard 33 and fuselage mounting plate 41, when
Adjusted while the being adapted to property of structure of mainboard 33 is so installed if fuselage mounting plate 41 is not separately provided.No matter such as
What, the key point with the mounting mode of casing itself and non-present invention can refer to the prior art if necessary.
It is fixedly installed with gear-box 17 on installation mainboard 33, and is provided with motor 11, motor 11 can be rotating electric machine,
It can also be with other power parts such as hydraulic motor.Motor 11 can be arranged directly on installation mainboard 33, also may be mounted at tooth
To be fixedly mounted on installation mainboard 33 indirectly on roller box 17.
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 setting phase
Pair concept, some special value should be utterly defined in by being not meant as its vertical angle.
The output axis connection of motor 11 simultaneously drives pinion shaft 15, so as to drive pinion gear 16 to rotate.Pinion shaft
15 bottom end can be connect by pinion flange 18 with gear-box 17.
Support panel seat 35 is also equipped on installation mainboard 33, the basic function of support panel seat 35 is support dependency structure,
Though therefore need not be strict with, it should be generally horizontally disposed with, and install the substantially vertical setting of mainboard 33.
Head 2 is carried by installation mainboard 33, and can be rotated relative to installation mainboard 33；The periphery of head 2 is into one
Step is set with the gear wheel 24 of synchronous rotation, and gear wheel 24 is engaged with pinion gear 16, is both set in gear-box 17.
Sewing machine provided by the present invention, head can be rotated relative to support panel seat 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.
Gear wheel and pinion gear are arranged in gear-box, and lubrication and dust-proof effect are more preferable, run relatively reliable.
Furthermore, it is possible to do some other improvement to sewing machine provided by the present invention.
The output shaft of rotating electric machine or other motors 11 can directly be connect with pinion gear 16, can also pass through retarder
12 connect with pinion gear 16.
The mounting means of retarder 12 can be designed further, for example, can install retarder at the top of gear-box 17
Retarder 12 is set to the top of retarder mounting base 13 by mounting base 13.
Retarder mounting base 13 can be designed as frame structure, at the top and bottom of frame space in can be used to be arranged
Shaft coupling 14.
The component relevant to lifting such as cylinder 31, cylinder mounting plate 32, buffer 34 can be set in figure, can also take
Disappear.
Arrangement above can advanced optimize the structure of equipment, realize stable work shape in simple structure
State.
Rotation set 23 can be set to across gear-box 17, and can pacify between the top of rotation set 23 and the roof of gear-box 17
Axle sleeve 191 is loaded onto, Lower shaft sleeve 192 can be installed between the lower part of rotation set 23 and the bottom wall of gear-box 17.Upper shaft sleeve 191 is under
Axle sleeve 192 also could alternatively be linear bearing.
In addition, positioning retainer ring 25 can also be arranged in the periphery of rotation set 23.
In this way, about 23 two position of rotation set is by 17 located lateral of gear-box, it is convenient to omit the correlations such as line slide rail
Component has advanced optimized product structure.
The top of rotation set 23 can install slip ring 21；Specifically, rotation set 23 can be fixedly connected and coaxially be arranged
Slip-ring rotor 212, the top of slip-ring rotor 212 can further be rotatablely connected coaxially setting slip ring stator 211；Slip ring is fixed
Son 211 is fixedly connected by slip ring check plate 22 with support panel seat 35.
Flange 193 can be set in the bottom of rotation set 23, and head 2 realizes the connection with rotation set 23 by flange 193.
The setting of the above rotation set 23 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 present invention is described in detail above.Specific case used herein is to the present invention
Principle and embodiment be expounded, method and its core of the invention that the above embodiments are only used to help understand
Thought is thought.It should be pointed out that for those skilled in the art, without departing from the principle of the present invention,
Can be with several improvements and modifications are made to the present invention, these improvement and modification also fall into the protection scope of the claims in the present invention
It is interior.
