Description of drawings
Fig. 1 is the structural representation of the utility model based on the single axle table single pendulum milling head;
Fig. 2 is the enlarged drawing of locating cone among Fig. 1;
Fig. 3 is the cutaway view by the single axle table (vertical) of AC permanent-magnet synchronous external rotor torque motor driving.
The specific embodiment
One, the single axle table that drives by AC permanent-magnet synchronous external rotor torque motor
For the utility model is described, earlier with reference to the single axle table of figure 3 explanations by the AC permanent-magnet synchronous external rotor torque motor driving, the difference of single axle table and the used turntable of the utility model is among the figure, the vertical setting of the turntable of Fig. 3, and the used turntable of the utility model needs horizontal setting, and principle is in full accord.By the explanation of Fig. 3 electric machine structure, help understanding single pendulum milling head of the present utility model.Among Fig. 3, the rotor 5 ' of motor directly links to each other with turntable table top 2 ', and table top 2 ' utilizes the end of bolting in rotor 5 ' usually.Simultaneously, the fixing housing 9 ' of the stator 6 ' that is positioned at rotor 5 ' inner ring and turntable is connected by bolt.The anglec of rotation of turntable is 360 ° * n (n represents revolution).
Be placed with permanent magnet on the inwall of rotor 5 ', be provided with braking mechanism 4 ' in rotor exterior.In addition,, designed the interior cold cover 8 ' of outer rotor torque motor, be positioned at the inside of the stator 6 ' that constitutes by silicon steel sheet and coil windings for source stator coil winding cools off to the motor feels hot effectively.Cooling circuit can adopt spiral cooling bath, also can adopt the dioptric type cooling bath.In order to make the height of turntable reduce, selected the axial/radial bearing 1 ' of turntable special use for use, the YRT series axis that this bearing is selected INA company for use is to/journal bearing, and this bearing can bear axially and radial load and heeling moment simultaneously, and bearing width is very little.For the position of detection rotor, bearing is provided with encoder 7 '; Also can on the axle that rotor drives, encoder 7 ' be set, sensing element perhaps otherwise be set, as long as can monitor the angle of rotation.Among Fig. 3,, need not on axle, to adorn in addition again encoder, therefore can utilize the space of bearing inner ring to carry out the distribution of threading and water route oil circuit owing to carry encoder on the bearing.In order to guarantee sealing property, between turntable and torque motor housing, be provided with lip seal circle 3 '.
Under the optimal way, the utility model is based on the single pendulum milling head of single axle table, and its single axle table is driven by above-mentioned AC permanent-magnet synchronous external rotor torque motor.
Two, the utility model is based on the single pendulum milling head of single axle table
As shown in Figure 1, the single axle table 4 of horizontal setting, therefore the card of its floral disc 5 is mainly used in the fixedly electric main spindle box 2 of milling head 1, all has relatively high expectations for form and position tolerance such as the machining accuracy of card, Circular Run-out Tolerance and surface smoothness.Only in this way, the card of floral disc 5 is just reliable as the rotating shaft locating surface.
At single axle table 4 centers through hole is arranged all generally, the afterbody of locating cone 3 is installed in the centre bore of single axle table 4 and with the coaxial setting of turntable, its connected mode relies on screw to be fixed on the floral disc 5 or by linkage unit and directly is connected with rotor.One end of locating cone 3 is provided with the short conical surface of protrusion, when assembling, the electric main spindle box 2 that electric main shaft 1 has been installed is sling, electricity main spindle box one side is provided with locating hole, fully cooperate (the short conical surface and planar section shown in A among Fig. 3 on the locating cone have guaranteed the electric main spindle box centre of gyration and the coaxial setting of the single axle table centre of gyration) with the short conical surface of 7:24 on the locating cone 3.After adjusting, T shape piece 6 is inserted in the T type groove of floral disc 5, then screw is passed the through hole of electric main shaft casing 2, be fixed into T shape piece 6, thereby electric main shaft casing 2 be locked on the floral disc 5 of single axle table 4.
Because T shape piece 6 inserted in the electric main spindle box 2, so T shape piece 6 can transmit moment of torsion, but can not guarantee backlass fully.For this reason, utilize the wedge shape briquetting to insert the both sides of T shape piece 6, the through hole from electric main spindle box 2 passes screw, locks the wedge shape briquetting simultaneously, utilizes the wedge shape briquetting that T shape piece 6 is clamped, and has thoroughly eliminated backlass.In addition, utilize the through hole at single axle table 4 centers, main shaft cable and water oil pipeline can be set.
Above-mentioned is the embodiment of the utility model the best, also can suitably change as required certainly, for example establishes mode of key and keyway etc. in addition in order to transmit moment of torsion.Therefore; the above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
