Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on 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. 4 is please referred to, Fig. 1 illustrates for a kind of overall structure of the provided sewing machine of specific embodiment of the present invention Figure;Fig. 2 is the overall structure diagram of head connection component and upper head in Fig. 1;Fig. 3 is the vertical of head connection component in Fig. 1 Body schematic diagram;Fig. 4 is the schematic cross-sectional view of Fig. 1 bottom bracket axle mounting means.
In a specific embodiment, sewing machine provided by the present invention includes frame base mechanism 01 on the whole, And table top 02, fuselage 03 and the feeding mechanism being supported by it, the feeding mechanism specifically include X to feeding mechanism 05 and Y-direction Feeding mechanism 06, the lower section of table top 02 are equipped with lower head 07 and drive the lower rotating mechanism 08 of lower head 07, on fuselage 03 also Rotating mechanism 09 and upper head 2 are installed, upper head 2 is specifically the head connection component 1 for being connected to rotating mechanism 09.
Upper head 2 is mounted by head connection component 1.Head connection component 1 is directly realized by by installation mainboard 33 and casing Mounting, can also be realized by installation mainboard 33 and fuselage mounting plate 41 with the mounting of casing, if do not set individually certainly Adjusted while the being adapted to property of structure of mainboard 33 is installed if setting fuselage mounting plate 41.Anyway, with the mounting of casing The key point of mode 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 with gear-box 17.
Upper head 2 is carried by installation mainboard 33, and can be rotated relative to installation mainboard 33;The periphery of upper head 2 It is further set with the gear wheel 24 of synchronous rotation, gear wheel 24 is engaged with pinion gear 16.
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.
For example, pinion gear 16 instead a small pulley can be no longer arranged in the output shaft of motor 11;Meanwhile Gear wheel 24 is no longer arranged in the periphery of upper head 2, and a big band being connected by synchronous belt with the small pulley is separately arranged Wheel.In this way, realizing power transmission by transmission belt, caused by this manufacture and assembly for being conducive to eliminate associated components accidentally Difference, and then be conducive to the stable operation of equipment.
For another example, the output shaft of rotating electric machine or other motors 11 can directly be connect with pinion gear 16, can also be passed through Retarder 12 is connect with pinion gear 16.
The mounting means of retarder 12 can also be designed further, be slowed down for example, can install at the top of gear-box 17 Retarder 12 is set to the top of retarder mounting base 14 by device 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.
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 may be replaced by 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 upper head 2 realizes the connection with rotation set 23 by flange 193.
The setting of the above rotation set 23 and its related accessory, can make rotating through for upper head 2 by simple structure Cheng Gengwei is 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.
