Description

The moon delineation bit architecture of sewing-machine rotating shuttle shuttle race

Technical field

The utility model is related to a kind of rotating shuttle structure, more particularly to a kind of quick and easy for installation, positions reliable and uniformity Well, the moon delineation bit architecture of sewing-machine rotating shuttle shuttle race.

Background technology

Rotating shuttle is the important composition part of sewing machine, the lock-type chain stitch suture most generally used in the industries such as clothing shoemaking On formula sewing machine, mostly using rotating shuttle, wire loop is caught on the spur of rotating shuttle during work, while expanding wire loop, and wire loop ring is guided Bypass shuttle frame and constitute lock-type chain stitch.General combined by shuttle race, shuttle frame and bobbin case and the moon circle being fixed on outside shuttle race of rotating shuttle and Into moon circle therein is to constitute one of critical component of rotating shuttle, and assembly precision requires higher, but existing moon circle typically passes through Left and right two screws are fixed on shuttle race outer ring surface, need to be confirmed repeatedly during installation after position of positioning hole, and dismounting moon circle, again When installing moon circle, often the moon, circle position data was inconsistent, and deviation occurs for front-month circle position, directly affects using effect and performance.

The content of the invention

The utility model mainly there is provided a kind of quick and easy for installation, position reliably and uniformity is good, so as to ensure that The moon delineation bit architecture of the sewing-machine rotating shuttle shuttle race of rotating shuttle performance, is needed when solving moon circle installation present in prior art When confirming to reinstall moon circle repeatedly after position of positioning hole, dismounting, deviation can occur for Yue Quan positions, directly affect rotating shuttle and use effect The technical problem of fruit and performance etc..

Above-mentioned technical problem of the present utility model is mainly what is be addressed by following technical proposals：A kind of sewing machine rotation The moon delineation bit architecture of sacsaoul bed, including shuttle frame and the bobbin case that is fixed on the shuttle frame fuse of shuttle frame one end, in the other end of shuttle frame Interworking is covered with the shuttle race that can be rotated relative to shuttle frame fuse, moon circle is provided with the outer ring surface of shuttle race, at the two ends of the moon circle Be respectively equipped with a moon circle hole, the moon circle hole extend to form conical surface positioning boss towards shuttle race, it is corresponding with moon circle hole Shuttle race is provided with taper positioning hole, and conical surface positioning boss interworking is plugged in taper positioning hole and fixed by screw.By The moon encloses the conical surface positioning boss and taper positioning hole setting interworking between shuttle race, the cone that shuttle race passes through interworking with the moon circle during assembling Face positioning boss and taper positioning hole are automatically positioned, not only quick and easy for installation, and positioning is reliable, are repeated several times after dismounting, position Put that uniformity is good, so as to be effectively guaranteed the performance and using effect of rotating shuttle.

Preferably, being folded with wool felt between the outer ring surface of the moon circle and shuttle race.The moon circle and shuttle race between sheep is set Felt, you can pass through the certain lubricating oil of wool felt adsorption storage, it is ensured that rotating shuttle lubrication is abundant.

As it is further preferred that shuttle race outer ring surface corresponding with the wool felt is provided with wool felt locating slot, wool felt setting-in In wool felt locating slot.Wool felt is inlaid in wool felt locating slot, it is ensured that corresponding blowdown gap position is accurate on wool felt Really, positioning method is simple and reliable.

Preferably, track platform is provided with the inner ring surface of the shuttle race, provided with annular shuttle frame on the outer ring surface of shuttle frame Guide rail, shuttle frame is slidably connected by being kept on the annular in-orbit platform where rites are performed of shuttle frame guide supporting and with the inner ring surface of shuttle race, with annular The corresponding track platform surface of shuttle frame guide rail be provided with several Sediment traps, Sediment trap corresponding with moon circle stretch out to be formed blowdown lack Mouthful, blowdown breach stretches out and connected on the outer ring surface of moon circle again.Multiple Sediment traps are set by the surface of in-orbit platform where rites are performed, The dirt produced in sewing process can be sent in Sediment trap at any time by the rotation of shuttle race, then is directly arranged by blowdown breach Go out outside rotating shuttle, thus avoid outlet from having some setbacks, the generation of the failure such as wire jumper, broken string；Sediment trap also reduces annular shuttle frame and led simultaneously The area of sliding friction surface between rail and track platform, reduces friction, accelerates radiating, extends the service life of rotating shuttle.

Therefore, the moon delineation bit architecture tool of sewing-machine rotating shuttle shuttle race of the present utility model has the advantage that：Shuttle race and Yue Quan It is automatically positioned by the conical surface positioning boss and taper positioning hole of interworking, it is not only quick and easy for installation, and positioning is reliable, repeatedly Repeat after dismounting, location consistency is good, so as to ensure that the performance and using effect of rotating shuttle；The moon circle and shuttle race between set Wool felt, you can pass through the certain lubricating oil of wool felt adsorption storage, it is ensured that rotating shuttle lubrication is abundant；Pass through the surface of in-orbit platform where rites are performed Set the dirt produced in multiple Sediment traps, sewing process to be sent at any time in Sediment trap by the rotation of shuttle race, then lead to Blowdown breach is crossed to be expelled directly out outside rotating shuttle, thus avoid outlet from having some setbacks, the generation of the failure such as wire jumper, broken string.
