In order to make technical problem to be solved by this invention, technical scheme and beneficial effect clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
The invention provides the electrical micro-machine transmission mechanism, comprise: motor-driven mechanism and follower, described motor-driven mechanism comprises motor and the driving-disc that connects together with motor, described follower comprises clutch plate, described driving-disc and described clutch plate are oppositely arranged, and described driving-disc one end end face evenly is fixed with some the first magnet; Described clutch plate one end end face evenly is fixed with some the second magnet; Described some the first magnet and some the second magnet are oppositely arranged; Described some the first magnet attracts each other; Described some the second magnet is attracted each other each other; Described some the first magnet and described some the second magnet are attracted each other in pole orientation.This structural design is saved the connector of knowing clearly between driving-disc and the clutch plate, by being arranged on the magnet of attracting each other on driving-disc and the clutch plate, the transmission of power of driving-disc to clutch plate, is realized the effect of connector, saved design cost and manufacturing cost.
Below in conjunction with specific embodiment and accompanying drawing in detail the present invention is described in detail.
With reference to figure 1 and Fig. 2, the present invention mainly comprises motor-driven mechanism 1 and follower 2.Please refer to Fig. 2.Among Fig. 2, motor-driven mechanism 1 comprises: motor 18, shaft coupling 16 and driving-disc 11.Driving-disc 11 1 ends are discoid, and the other end is that the round bar shape that stretches out from discoid centre, shaft coupling 16 1 ends be connected connections, the round bar shape end connection that the other end is connected with driving-disc with motor, junction at shaft coupling 16 and driving-disc 11 is arranged with nut 14, to prevent driving-disc 11 axial endplays.Motor 18 drives driving-disc 11 rotations by shaft coupling 16.Nut 14 upper surfaces, driving-disc 11 round bar shapes one end are arranged with clutch shaft bearing 13-1, the second bearing 13-2, with support drive dish 11.Clutch shaft bearing 13-1, the second bearing 13-2 arranged outside have their public driving-disc fixed covers 12.Motor 18 upper end end faces are fixedly installed a discoid motor joint pin holder 17; The some motor joint pins 15 that connect driving-disc fixed cover 12 and 17 effects of motor joint pin holder evenly have been provided with between motor joint pin holder 17 upper surfaces and driving-disc fixed cover 12 lower surfaces.Driving-disc 11 discoid end end faces are processed with first ring connected in star 111, and first ring connected in star 111 is interior to be distributed with some the first magnet 19 along even circumferential, and every adjacent two first magnet, 19 magnetic poles are opposite and all the first magnet 19 size specifications are identical.Whole motor-driven mechanism 1 is fixed on the mount pad (mount pad is not shown in the drawings).
Please continue with reference to figure 2, follower 2 comprises: clutch plate 22 and collet assembly 21.Clutch plate 22 is discoid, is provided with straight-through internal thread 222 along the medium position of its disk upper and lower end face.Collet assembly 21 comprises: collet 210, collet holder 211, spring 212 and collet locking nut 213.Collet 210 is used for the parts that clamping need to be processed.Collet holder 211 is cylindric, axially is processed with inner via hole 2111 along it, is processed with the external screw thread 2110 that mates with internal thread 221 at its end excircle.One end of collet holder 211 and clutch plate 22 are threaded by external screw thread 2110 and internal thread 222.Collet 210 inserts the inner via hole 2111 of collet holder 211.Spring 212 is arranged in the madial wall and the space between collet 210 excircles of inner via hole 2111.Collet locking nut 213 is screwed into internal thread 222 from clutch plate 22 lower ends, holddown spring 212.Collet assembly 21 is fixed on the clutch plate, and the part that needs are processed is clamped on the collet 210, thereby makes processed part along with clutch plate rotates together, under the machining equipment effect, finishes part processing.
In Fig. 2, driving-disc 11 and clutch plate 22 both ends of the surface are oppositely arranged, and its relative distance is in the magnetic field range of some the first magnet 19 that are arranged on their inside and 24 generations of some the second magnet.Only in this way, could be with the transmission of power of driving-disc 11 to clutch plate 22.
Please refer to Fig. 3 and Fig. 4.By can finding out among Fig. 3, no matter be some the first magnet 19 the first ring connected in star 111 of driving-disc 11 in, or some second magnet 24 of interior the second annular groove 221 of clutch plate 22, they are attracted each other as magnetic pole is opposite each other between the individuality.Among Fig. 4, axially attract each other between some the first magnet 19 as a whole and the second magnet 24, radially mutually exclusive.
Whole follower 2 is installed on the movable platform (not shown), so the second magnet 24 of clutch plate 22 end faces can be near the first magnet 19 of driving-disc 11 but do not allow them inhale together each other.Behind the relative position of adjusting clutch plate 22 and driving-disc 11, fixedly follower 2.At this moment, starter motor 18, driving-disc 21 rotate thereupon, because the first magnet 19 and the second magnet 24 magnetic fields are radially repelled and axially attracted each other, clutch plate 22 has also kept and driving-disc 11 same rotating speeds, equidirectional rotation.Thereby reach the effect that the moment of driving-disc 11 is passed to clutch plate 22.Here it is why do not have between driving mechanism 1 and the follower 2 among the present invention jockey connect also can carry-over moment reason.
The collet 210 of follower 2 only need use mechanism that collet locking nut 113 tops are got final product when needs discharge processing component as shown in Figure 1 and Figure 2.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
