For the deficiencies in the prior art, the utility model provides a kind of drive unit of industrial sewing machine.
A kind of drive unit, is applied to industrial sewing machine, wherein, comprises
Drive unit body, described drive unit body is provided with an axle stretch end;
First housing, is dismountablely connected to the side that described drive unit body is provided with described axle stretch end, forms a cavity between described drive unit body and described first housing; Described cavity inside arranges an encoder, and described encoder connects described drive unit body by described axle stretch end.
Preferably, described axle stretch end is provided with the groove mating described encoder.
Preferably, described encoder comprises encoder lenticular lenses assembly, motor encoder assembly, described encoder lenticular lenses assembly is provided with the projection with described matching grooves, and described encoder lenticular lenses assembly is set in described axle stretch end and is fixedly installed on described motor encoder component internal.
Preferably, described encoder lenticular lenses assembly comprises the first jump ring, the first jump ring pad, lenticular lenses, lenticular lenses fixture, second jump ring, the second jump ring pad, described first jump ring, the first jump ring pad, lenticular lenses, lenticular lenses fixture, the second jump ring, the second jump ring pad are set with successively and connect described axle stretch end.
Preferably, described lenticular lenses is provided with projection, and described projection engaging is installed in described groove.
Compared with prior art, the utility model has the following advantages: using the shaft extension of drive unit body as the central shaft of encoder, encoder is fixedly connected on drive unit body, and fixed by the first housing, this kind of connected mode, receive simple, encoder directly can obtain the running status of drive unit body, decrease the generation of driving error, improve the degree of accuracy of encoder Information Monitoring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as restriction of the present utility model.
As shown in Figure 1, a kind of drive unit, is applied to industrial sewing machine, wherein, comprises
Drive unit body 1, described drive unit body 1 is provided with an axle stretch end 10;
First housing 11, is dismountablely connected to the side that described drive unit body 1 is provided with described axle stretch end 10, forms a cavity between described drive unit body 1 and described first housing 11; Described cavity inside arranges an encoder 2, and described encoder 2 is set in described shaft extension and connects described drive unit body 1.
In the utility model, central shaft using the shaft extension of drive unit body 1 as encoder 2, encoder 2 is fixedly connected on drive unit body 1, and fixed by the first housing 11, this kind of connected mode, receive simple, encoder 2 directly can obtain the running status of drive unit body 1, decrease the generation of driving error, improve the degree of accuracy of encoder 2 Information Monitoring.
As further preferred version, described axle stretch end 10 is provided with the groove mating an encoder 2.Can regular coding device 2 further by groove, make the work that encoder 2 can be stable.
As further preferred version, described encoder 2 comprises encoder 2 lenticular lenses assembly, motor encoder 2 assembly 21, described encoder 2 lenticular lenses assembly is provided with the projection with described matching grooves, and described encoder 2 lenticular lenses assembly is set in described axle stretch end 10 and is fixedly installed on described motor encoder 2 assembly 21 inside.Further, described encoder 2 lenticular lenses assembly comprises the first jump ring 22, packing ring 23, first jump ring pad 24, lenticular lenses fixture 25, lenticular lenses 26, second jump ring 28, second jump ring pad 27, described first jump ring 22, packing ring 23, first jump ring pad 24, lenticular lenses 26, lenticular lenses fixture 25, second jump ring 28, second jump ring 28 pad 27 are set with successively and connect described axle stretch end 10.First jump ring 22, first jump ring pad 24, second jump ring 28, second jump ring pad 27 is set, can lenticular lenses and lenticular lenses fixture be fixedly mounted in the shaft extension of drive unit body 1, prevent lenticular lenses under the state of drive motors body high-speed cruising, shift phenomenon occurring simultaneously, the operating state signal avoiding encoder 2 to get mistake transfers to control system, and what provide industrial sewing machine makes the degree of accuracy.
As further preferred version, described lenticular lenses 26 is provided with projection, and described projection engaging is installed in described groove.Prevent lenticular lenses under the state of drive motors body high-speed cruising, shift phenomenon occurring further.
The foregoing is only the utility model preferred embodiment; not thereby embodiment of the present utility model and protection domain is limited; to those skilled in the art; should recognize and all should be included in the scheme that equivalent replacement done by all utilization the utility model descriptions and diagramatic content and apparent change obtain in protection domain of the present utility model.
