Abstract
The utility model relates to an interior concealed electricity main shaft, including the main shaft main part, and locate the main shaft tailstock of main shaft main part one end, the main shaft main part includes main shaft and motor and as an organic wholeization structure. The utility model has the advantages of electric main shaft with the same power of tradition machinery main shaft can carry out high -speed machining, main shaft and motor formula structure as an organic whole, the noise descends 23% under the equal rotational speed condition, owing to left out mechanical structure, when the dynamic balance is corrected, only need to correct electric main shaft body, correct the flow and simplify, correct the degree of difficulty and reduce, the action of main shaft location is simplified, only needs the positioner of motor side just can realize the location.
Description
Technical field
This utility model relates to a kind of electro spindle, particularly relates to a kind of concealed electric main shaft.
Background technology
The main shaft of traditional machine tool adopts the structure such as belt pulley, gear to be connected with spindle motor, owing to adopting gearing structure, all creates certain restriction for the noise of main shaft, dynamic balancing adjustment and high rotating speed control aspect, and common problem is as follows:
1) belt pulley owing to adopting, gear box structure, the noise of main shaft is relatively larger；
2) owing to have employed mechanical transmission structure, lathe is when adjusting dynamic balancing, it is necessary to adjust the frame for movements such as motor, spindle machine body, belt pulley, adjusts complexity；
3) owing to adopting belt transmission, the maximum speed 10000rpm of conventional master spindle, due to the restriction of frame for movement, it is impossible to improve rotating speed again, it is impossible to adapt to High-speed machining requirement.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of concealed electric main shaft, to solve deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions:
A kind of concealed electric main shaft, wherein, including spindle main body, and is located at the main shaft tailstock of described spindle main body one end, and described spindle main body includes main shaft and motor and is integrated.
Above-mentioned concealed electric main shaft, wherein, the described spindle main body other end is provided with positioning key, is provided with mounting seat bottom described spindle main body.
Above-mentioned concealed electric main shaft, wherein, one end of described main shaft is provided with coolant joint, sealing gland joint, drifting dust joint, folder cutter joint, unloads cutter joint, power cord connector, signal wire joint and encoder joint.
Compared with the prior art, the beneficial effects of the utility model are in that:
--with the electro spindle of traditional mechanical main shaft equal-wattage, maximum speed, up to 25000rpm, can carry out High-speed machining；
--main shaft and motor are integral type structure, eliminate mechanical transmission structure, and under equal speed conditions, noise declines 23%；
--owing to eliminating frame for movement, when dynamic balancing is corrected, it is only necessary to correct electro spindle body, correct process simplification, correct difficulty and reduce；
--main shaft and motor are integral type structure, eliminate mechanical transmission structure, and main shaft orientation action simplifies, it is only necessary to the positioner of motor side just can realize location.
Accompanying drawing explanation
The accompanying drawing constituting a part of the present utility model is further appreciated by of the present utility model for providing, and schematic description and description of the present utility model is used for explaining this utility model, is not intended that improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the structural representation of this utility model concealed electric main shaft；
Fig. 2 is the cross-sectional view of this utility model concealed electric main shaft.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
It should be noted that when not conflicting, the embodiment in this utility model and the feature in embodiment can be mutually combined.
With reference to shown in Fig. 1, Fig. 2, this utility model concealed electric main shaft includes spindle main body 1, and is located at the main shaft tailstock 2 of spindle main body 1 one end, and spindle main body 1 includes main shaft and motor and is integrated.
In preferred embodiment of the present utility model, spindle main body 1 other end is provided with positioning key 3, is provided with mounting seat 4 bottom spindle main body 1.
With continued reference to diagram, one end of main shaft is provided with coolant joint 5, sealing gland joint 6, drifting dust joint 7, folder cutter joint 8, unload cutter joint 9, power cord connector 10, signal wire joint 11 and encoder joint 12, coolant joint 5 passes in and out joint for main shaft coolant, sealing gland joint 6 and drifting dust joint 7 are dust-proof pneumatic fitting, folder cutter joint 8 need to pass into 0.6MPa when working and compress air, reset for cylinder, main shaft to pass in the running always, need to temporarily disconnect when unloading cutter, unload cutter joint 9 and need to pass into 0.6MPa compression air, for unloading cutter, signal wire joint 11 connects tool changing ATC sensor, stator temperature transducer, power cord connector 10, the power line that signal wire joint 11 and encoder joint 12 each connect, holding wire and encoder wiring all bands shield.
From the above it can be seen that advantage of the present utility model is in that:
--with the electro spindle of traditional mechanical main shaft equal-wattage, maximum speed, up to 25000rpm, can carry out High-speed machining；
--main shaft and motor are integral type structure, eliminate mechanical transmission structure, and under equal speed conditions, noise declines 23%；
--owing to eliminating frame for movement, when dynamic balancing is corrected, it is only necessary to correct electro spindle body, correct process simplification, correct difficulty and reduce；
--main shaft and motor are integral type structure, eliminate mechanical transmission structure, and main shaft orientation action simplifies, it is only necessary to the positioner of motor side just can realize location.
Above specific embodiment of the utility model being described in detail, but this utility model is not restricted to particular embodiments described above, it is intended only as example.To those skilled in the art, any equivalent modifications and replacement are also all among category of the present utility model.Therefore, impartial conversion done under without departing from spirit and scope of the present utility model and amendment, all should be encompassed in scope of the present utility model.
