Abstract
The utility model discloses a combined multiple electric spindle unit, which comprises a shell. A plurality of sets of electric spindle units are arranged in the shell. Each electric spindle unit comprises a rotating shaft, a supporting bearing, an internal motor rotor and a stator, wherein both ends of the rotating shaft are fixed in the shell through the supporting bearing; and the middle part of the rotating shaft is connected with the internal motor rotor and the stator. The combined multiple electric spindle unit has the beneficial effects that the characteristic of single independent structure of the current electric spindle is changed; two or more sets of electric spindles with same or different structures, parameters and the like are integrated into the combined multiple electric spindle unit of which the electric spindle units share one shell; the combined multiple electric spindle unit has a compact structure, a high space utilization rate and few required materials; and the parallel or ordering linkage actions can be realized, so that one or one group of actions of a machine tool can carry out simultaneous processing on a plurality of positions or a plurality of workpieces, and thus, the aims of improving the utilization rate and the processing efficiency of the machine tool, shortening the processing period, saving the production cost and improving the economic benefits are fulfilled.
Description
Technical field
The utility model relates to knockdown how electric main axle unit in a kind of mechanical engineering field of field.
Background technology
The electricity main shaft is a kind of typical dynamo-electric functional part, it is combined as a whole spindle drive motor and main shaft, realize motor---the function of integrated spindle axisization, make and be " zero transmission " between motor and the main shaft, be easy to reach high speed, high-precision, efficient and modular characteristics, wide model is applied to various modern Digit Control Machine Tools.In some production and processing occasion, a machine tool exists some repeatability, similitude and regular work.The form that employed electric main shaft all is single rotating shaft in the middle of the present production and processing also has bigger limitation aspect process-cycle and production efficiency, above-mentioned limitation is improved.
Because therefore the defective that above-mentioned existing electric main shaft exists needs a kind of novel electric main axle unit of exploitation, the form that adopts a plurality of electric main shafts to make up is applied to Digit Control Machine Tool.
The utility model content
Main purpose of the present utility model is, overcome the defective that existing electric main shaft exists, and provide a kind of knockdown how electric main axle unit of new structure, technical problem to be solved is to make it in the processing work of some repeatability, similitude and regularity, realize parallel or the order interlock, processing when one of lathe or set can be carried out multi-section position or multiplex's part, therefore the process-cycle can have been shortened, significantly improve working (machining) efficiency, reach and save production cost the purpose of increasing economic efficiency.
The purpose of this utility model and solve its technical problem and realize by the following technical solutions.A kind of knockdown how electric main axle unit according to the utility model proposes comprises shell, is provided with the electric main axle unit of many covers in the described shell.
The purpose of this utility model and solve its technical problem and also can be applied to the following technical measures to achieve further.
Aforesaid knockdown how electric main axle unit, wherein said described electric main axle unit comprises rotating shaft, block bearing, inner electric machine rotor and stator, the two ends of described rotating shaft are fixed in the described shell by described block bearing, and the middle part of described rotating shaft is connected with described inner electric machine rotor and stator.
By technique scheme, the knockdown how electric main axle unit of the utility model has following advantage at least:
1. change the characteristics of the single absolute construction of present electric main shaft, the utility model is gathered two covers or identical or different electric main shafts such as many nested structures, parameter, become the how electric main axle unit of combined type of a shared shell, compact conformation, space availability ratio height, material requested are few.
2. can realize parallel or order interlock action, processing when making one of lathe or set can carry out multi-section position or multiplex's part, the purpose that reach the utilization rate that improves lathe and working (machining) efficiency, shortening process-cycle, saves production cost, increases economic efficiency.
In sum, the knockdown how electric main axle unit of the utility model special construction, it has above-mentioned many advantages and practical value, thereby is suitable for practicality more.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
Description of drawings
Fig. 1 is the schematic diagram of the knockdown how electric main axle unit of the utility model.
The specific embodiment
For further setting forth the utility model is to reach technological means and the effect that predetermined utility model purpose is taked, below in conjunction with accompanying drawing and preferred embodiment, to the specific embodiment of the present utility model describe in detail as after.
As shown in Figure 1, a kind of knockdown how electric main axle unit comprises shell 5, and shell 5 comprises drive end bearing bracket 7 and rear end cap, is provided with the electric main axle unit of three covers in the shell 5, is respectively first electric main axle unit 1, second electric main axle unit 1.1 and the 3rd electric main axle unit 1.2.The electric main axle unit of every cover comprises rotating shaft 3, block bearing, inner electric machine rotor 9 and inner electric machine stator 4, the front end of rotating shaft 3 and end are fixed in the enclosure by first block bearing 8 and second block bearing 2 respectively, and the middle part of rotating shaft 3 is connected with inner electric machine rotor 9 and inner electric machine stator 4.Be provided with cooling duct 6 in the shell 5, can realize cooling to electric main axle unit, three electric main axle units can be simultaneously or respectively separately control use, realize parallel or order interlock action, processing when making one of lathe or set can carry out multi-section position or multiplex's part, the purpose that reach the utilization rate that improves lathe and working (machining) efficiency, shortening process-cycle, saves production cost, increases economic efficiency.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
