Embodiment
The present invention mainly provides a kind of motor that allows same size form, the modular type axle that corresponding plurality of sewing machines quick mounting is used connects structure, as the modular type axle of Fig. 2 first embodiment of the invention connects structural texture exploded view, Fig. 3 modular type axle of the present invention connects as shown in the STRUCTURE DECOMPOSITION figure that constructs the first usage mode, modular type axle of the present invention connects structure, consist essentially of: one first be coupling piece 30, one second be coupling piece 40, a contiguous block 50 and at least one axle sleeve 60; Wherein:
This first piece 30 that is coupling is located at the axle head of a motor shaft 21, convexes with a plurality of the first dogs 31 with predetermined spacing configuration on its end face; In the present embodiment, this first piece 30 that is coupling utilizes screw 91 to be locked in the axle head of this motor shaft 21.
This second is coupling piece 40 for being installed on the headstock axle 11A of a sewing device, the center is provided with first axis hole 41 penetrating for headstock axle 11A, its periphery convexes with a plurality of the second dogs 42 with predetermined spacing configuration, on each second dog 42, is respectively equipped with first screw hole 43 communicating with this first axis hole 41.
This contiguous block 50 is coupling between piece 40 for being installed on this first piece 30 and this second that be coupling, its for this first side that piece 30 is connected that is coupling, be provided with a plurality of the first grooves 51 of filling in for each the first dog 31 correspondences respectively, its for this second side that piece 40 is connected that is coupling, be provided with the second grooves 52 that a plurality of each the second dog 42 correspondences of confession are respectively filled in.
This at least one axle sleeve 60 second is coupling in the first axis hole 41 of piece 40 for being inserted in this, the outside dimension of each axle sleeve 60 just can with the firm fit of this first axis hole 41, each axle sleeve 60 and be provided with the second axis hole 61 of a tool preliminary dimension respectively at its one end, each axle sleeve 60 peripheral and be provided with a plurality of first pilot holes 62 of configuring and with this second axis hole 61 communicating corresponding to each first screw hole 43 respectively.
In principle, when modular type axle of the present invention connects structure use, can be as shown in Figure 3, directly second piece 40 that is coupling is sheathed on the headstock axle 11C of a sewing device, because second the be coupling aperture size of the first axis hole 41 of piece 40 is just identical with the outside dimension of headstock axle 11C in figure, therefore do not need to install additional axle sleeve, can allow second firm being sheathed on headstock axle 11C of piece 40 that be coupling, recycle a plurality of screws 92 screw in respectively second be coupling piece 40 the first screw hole 43 and prop up the mode of headstock axle 11C, second piece 40 that is coupling is locked on headstock axle 11C really.
In addition contiguous block 50 plug sleeves are coupling between piece 40 in first piece 30 and second that is coupling, the headstock axle 11C that can form fast sewing device is connected with motor shaft 21, and make the headstock axle 11C of sewing device can be with the object of motor shaft 21 rotation, integral module formula axle connection structure can form fast motor shaft and be connected with the headstock axle of sewing device, not only contribute to promote the assembling production capacity of sewing device, more can obtain comparatively solid and reliable axle and connect effect, contribute to promote the running quality of sewing device.
As Fig. 2, shown in Fig. 4 and Fig. 5, the external diameter of the original headstock axle of another sewing device 10A 11A installing when 20 wishs of motor, relatively be less than second while being coupling the first axis hole 41 aperture of piece 40, the axle sleeve 60 that can select the aperture of the second axis hole 61 to conform to the external diameter of headstock axle 10A in figure is installed on headstock axle 11A and second and is coupling between the first axis hole 41 of piece 40, utilize equally a plurality of screws 92 to screw in respectively the second the first screw hole 43 that is coupling piece 40, and through the first pilot hole 62 of axle sleeve 60, prop up the mode of headstock axle 11A, second piece 40 that is coupling is locked on headstock axle 11A really.
Same, only need be again contiguous block 50 plug sleeves be coupling between piece 40 in first piece 30 and second that is coupling, as shown in FIG. 6 and 7, can form the headstock axle 11A that external diameter is relatively little is connected with motor shaft 21, reach and can allow the motor of same size form, the object that corresponding plurality of sewing machines quick mounting is used; Comparatively speaking, more contribute to promote assembling production capacity and the quality of sewing device.
Moreover, as shown in Figure 8, modular type axle of the present invention connects structure, can further comprise at least one cushion block 70 and at least one grommet 80, each cushion block 70 and each grommet 80 have respectively predetermined thickness, each cushion block 70 is provided with respectively at its one end the trepanning 71 that an internal diameter conforms to the aperture of this first axis hole 41, and each cushion block is provided with second pilot hole 72 communicating with this trepanning 71 in the other end of this trepanning 71; The inner ring aperture of each grommet 80 conforms to the aperture of this first axis hole 41.
As shown in Fig. 8, Fig. 9 and Figure 10, the headstock axle 11B of another sewing device 10B that wants to install and use when motor 20 relatively in short-term, can select the grommet 80 of suitable thickness to be sheathed on headstock axle 11B, again the second be coupling piece 40 and cushion block 70 is locked on headstock axle 11B, finally utilize screw 93 through the second pilot hole 72 of cushion block 70 and screw in the screw hole 12 of headstock axle 11B axle head, can be really second piece 40 that is coupling being fixed on the headstock axle 11B of sewing device 10B with the state near sewing device 10B.
Same, as shown in FIG. 11 and 12, only need be again contiguous block 50 plug sleeves be coupling between piece 40 in first piece 30 and second that is coupling, can form the relatively short headstock axle 11B of length and be connected with motor shaft 21, make the motor 20 of same size be able to the shorter sewing device 10B of corresponding headstock axle 11B and install and use.
It is worth mentioning that, modular type axle of the present invention connects structure, no matter whether have cushion block 70 and grommet 80, integral module formula axle connects structure can further include a motor shaft; And, integral module formula axle connect structure also can be further in this second sheathed heat radiation wheel blade 23 on piece 40 that is coupling, further integrate modular motor 20 assemblies, contribute to control quantity and the cost of relevant spare part.
