Abstract
The utility model relates to the centre shuttle joining structure of a sewing machine. An upper shell body and a bottom shell body which are separated are punched into forming; a through hole and a hook tip are arranged on the upper shell body; a through hole and a wheel hub are arranged on the bottom shell body. The utility model is characterized in that a clamp convex part is arranged on the wheel hub of the bottom shell body; a corresponding gap is arranged at the position of the junction edge of the upper shell body and the bottom shell body; thereafter, the clamp convex part of the bottom shell body and the gap of the upper shell body are fastened to joint.
Description
The utility model relates to shuttle in a kind of Sewing machines, is shuttle joint construction in a kind of combined type Sewing machines specifically.
As everyone knows, phenomenon such as the rib device system part of an important indispensability is very made accidentally if having slightly on the quality in the general Sewing machines, will cause user's normal off line, and the seam clothing has some setbacks, the car pin is easily broken therefore require quality higher on making, and manufacturing cost is also very high.Thereby the manufacturing industry of manufacturing dealer of Sewing machines now and countries in the world is suitable competition.Figure 3 shows that shuttle stereo appearance figure among the Sewing machines of prior art, its similar half clam shell hollow shape include upper casing, lower casing, wheel hub and axle center, and whole forming processes is finished by the lathe grinding mode.Therefore lathe cuts and removes material, must cost many mental and physical efforts, operation and waste material.And formality is more miscellaneous during its operation, by a ball material cut out the after-baking shaping, more in addition lathe grinding remove institute need shape, after again with the punch press punching, miscellaneous tens of operation procedures such as polishing are handled.For a manufacturer, manpower, material, the cost that process velocity spent are difficult to calculate.Even if this upper shell 1 and drain pan 2 are separated making, high-temperature soldering in addition again, the precision (some deviation promptly can not be used) that also must careful attention just meets.Therefore, though rib is a slight part in this, really because of disturbing manufacturer and consumption user.
The purpose of this utility model be to provide a kind of easily manufactured, reduce cost, enhance productivity and combined type Sewing machines that precision is high in the shuttle joint construction.
To achieve these goals, the utility model adopts following technical scheme: rib joint construction in a kind of Sewing machines, upper shell separates punch forming with bottom shell body, and this upper shell is provided with perforation and bill, this bottom shell body is provided with perforation and wheel hub, and it is characterized in that: the wheel hub of this bottom shell body is provided with the clip protuberance, and this upper shell meets the edge place with this bottom shell body and is provided with relative breach, in view of the above, urgent and engage with the breach two-phase of the clip protuberance of this bottom shell body and upper shell.
Compared with the prior art the utility model has conspicuous advantage: it is fastening that the utility model adopts the clip protuberance with the breach of upper shell and bottom shell body accurately to engage, and can not produce the mistake that walks, and processing is got up, and is very convenient, and the product precision is also high; The punch forming respectively of upper shell and bottom shell body as long as in addition punching press is promptly plastic for the plate body of a preliminary dimension, is saved material, manpower and time, can produce in a large number, improves the competitiveness; Save in the past with welding manner and be difficult to shortcoming, make among the integral body shuttle surface and inner face smooth the splice grafting edge.
Below in conjunction with drawings and Examples the utility model is elaborated.
Fig. 1 is the three-dimensional exploded view of the utility model preferred embodiment;
Fig. 2 makes up schematic diagram for Fig. 1;
Fig. 3 is a shuttle schematic perspective view in the Sewing machines of prior art.
As depicted in figs. 1 and 2, in the utility model Sewing machines the shuttle joint construction its be shuttle body 40 in.This carina body is made up mutually by two housings, and this two housing is a upper shell 10 and a bottom shell body 20, and upper and lower casing is punch forming respectively.The shape of this upper casing complete 10 is identical with prior art, is a semicircle shape and has the radian face, and this radian face is provided with perforation 11 and outer circular edge is provided with flange 14, and this flange 14 is provided with the breach 13 of predetermined number, and is provided with a bill 12 in upper shell 10.This bottom shell body 20 still is a semicircular body and tool radian face in addition, this radian face is provided with than large perforation 21, in its outer rim is a wheel hub 24, this wheel hub is provided with the clip protuberance 23 of predetermined number protrusion, and this clip protuberance 23 and this breach 13 are relative and the size that matches arranged, with this upper shell of the urgent location of two-phase and drain pan, in these bottom shell body 20 affixed axle center, a chamber 30 of establishing.
