Abstract
The utility model relates to a feed driven device, which comprises a fixing unit, a driving unit arranged on the fixing unit, a leading screw screwed in the driving unit, and a moving member fixed on the leading screw. The driving unit is provided with a stator and a rotor arranged inside the stator; and the leading screw is screwed in the stator and displaces along the rotor axially by the driving of the rotor. Therefore, the feed driven device can utilize the rotor of the driving unit screwed on the leading screw, eliminate transmission medium, reduce the length of a driving element, and then can solve the problems of vibration deflection in the rotation due to deflection of centrifugal force caused by the drooping of the deadweight of the leading screw, and the like.
Description
[technical field]
The utility model relates to a kind of drive mechanism, particularly relates to a kind of feed drive unit that is applicable to processing machine.
[background technology]
As shown in Figure 1, the feed drive unit of existing a kind of comprehensive process machinery includes a board 1, a fulcrum and is located at driving screw 2 on this board 1, one and is screwed on this driving screw 2 and is subjected to this driving screw 2 to drive moving member 3 and the motors 4 in order to drive this driving screw 2 that axially produce displacements along this driving screw 2.And this motor 4 is to be installed on this board 1, and has an output shaft 401 with these driving screw 2 coaxial lines, and this output shaft 401 is mated condition and utilizes a shaft coupling 5 to be linked with this driving screw 2.Above-mentioned structure is to utilize shaft coupling 5 as medium, and to driving screw 2, driving screw 2 becomes power conversion this moving member 3 to do linear movement again, to reach feeding transmission purpose with the transmission of power of motor 4 output.
Though, this feed drive gearing has been widely used on the comprehensive process machinery, but following disappearance is arranged still in practical application: because motor 4 output shafts 401 must see through shaft coupling 5 with transmission of power to driving screw 2, so that the length of whole power transmission shaft more greatly, relatively take up room, so be easy to generate noise and vibration during running, and more stability is not fixed to cause rotating ratio.
[utility model content]
The purpose of this utility model is to be to provide a kind of to shorten drive link length and avoid drive link because the centrifugal force deflection causes the feed drive unit of the vibrations amount of deflection that is produced when rotating.
Feed drive unit of the present utility model comprises a fixture, one and is installed in the driver element of this fixture, a driving screw and a moving member that is installed in this driving screw that is screwed in this driver element.This driver element has a stator and a rotor that is installed in this stator interior, and this driving screw is to be screwed in this rotor, and is subjected to this rotor driving to produce displacement along this rotor axial.
The beneficial effects of the utility model are: utilize this driving screw to be screwed together in this rotor, and this moving member is fixedly arranged on this driving screw, then medium is transmitted in cancellation, not only shorten the length of whole power transmission shaft, and solve because the caused centrifugal force deflection of driving screw dead weight sagging causes the problems such as vibrations amount of deflection that produced when rotating.
[description of drawings]
Fig. 1 is the combination section of existing a kind of feed drive unit;
Fig. 2 is the combination section of a preferred embodiment of the utility model;
Fig. 3 is the three-dimensional exploded view of the above-mentioned preferred embodiment of the utility model.
[specific embodiment]
Below in conjunction with drawings and Examples the utility model is elaborated:
As shown in Figures 2 and 3, the preferred embodiment of the utility model feed drive unit comprises a fixture 10, one and is installed in the driver element 20 on this fixture 10, a driving screw 30 and a moving member 40 that is installed in this driving screw 30 that is screwed in this driver element 20.
The fixture 10 of present embodiment is the saddle (or base) that is installed on the comprehensive process machinery board, and has a positioning seat 11 that protrudes setting, and this positioning seat 11 is to be hollow form, and has an endoporus 111.
The driver element 20 of present embodiment is a motor, and has one and be installed in stator 21 in this endoporus 111, rotor 22 that is installed in these stator 21 inside and nut element that is installed in these rotor 22 inside 23, two bearing 24 and two cappings 25 that are arranged on described bearing 24 outsides that are set in 21 of this nut element 23 and this stators.This rotor 22 is hollow form, and the both sides that only are positioned at this positioning seat 11 are just supported in described capping 25.
This driving screw 30 is to be screwed in this nut element 23, and has a first end 31 and a second end 32 in these positioning seat 11 both sides respectively.
The moving member 40 of present embodiment is a workbench, and have a pedestal 41 and be installed in one first supporting seat 42 and one second supporting seat 43 of these pedestal 41 bottoms, this first and second supporting seat 42,43 is installed in respectively on first and second end 31,32 of this driving screw 30.
Whereby, again as shown in Figures 2 and 3, when power supply passes through stator 21 or rotor 22, produce magnetic interaction and rotor 22 is rotated, utilize this rotor 22 to drive this nut element 23 and rotate, and make this nut element 23 when rotating, drive the axial generation shift reciprocately of this driving screw 30 along this nut element 23 with respect to this fixture 10, and this moving member 40 also can produce shift reciprocately along with this driving screw 30, to reach the feeding driving purposes.
Therefore, the utility model omits the setting of shaft coupling, medium is transmitted in cancellation, and utilize this driver element 20 to be installed in the positioning seat 11 of this fixture 10, this driving screw 30 is screwed together in this nut element 23, and make the power output shaft of this nut element 23 as this rotor 22, then can shorten the length of whole power transmission shaft, can not take up room, and the utility model is applicable to the feed arrangement of long stroke, because reduce the length of drive link axle, and driving screw 30 does not rotate, can solve because the caused centrifugal force deflection of driving screw 30 dead weight sagging causes the problems such as vibrations amount of deflection that produced when rotating.Can not produce problems such as vibration, noise during these nut element 23 runnings, and rotating speed is more stable, and extensively applies to various linear drives.
