本发明涉及电动工具领域,特别涉及一种无传统定、转子电机的多功能机。The invention relates to the field of electric tools, in particular to a multifunctional machine without traditional stator and rotor motors.
摆动机(也称之为多功能机),其输出端为摆动形式,带动的工作头主要有锯片、切割片、抛光盘等。所用到的工作头可以是不同形状、不同大小、不同材质,如三角形、长条形、圆形和扇形等。Oscillating machine (also known as multi-function machine), its output end is in the form of swing, and the driven work heads mainly include saw blades, cutting blades, polishing discs, etc. The working heads used can be of different shapes, sizes, and materials, such as triangles, strips, circles, and sectors.
现有技术中的多功能机,其输出端也就是工作端的运动为一定角度范围内的圆周摆动,而动力来源则是具有定子、转子的电机,转子同时具有回转轴。在回转轴的前、后端至少各有一个轴承作为支撑,并且在电机上安装有用于冷却的风扇。多功能机通过偏心轴及安装在其上的轴承驱动摆杆绕输出轴做圆周摆动,摆杆与输出轴固定,从而使得输出轴随着摆杆做往复圆周转动,工作头与输出轴固定,当输出轴做往复圆周转动时,工作头在输出轴的带动下做往复摆动。In the multi-function machine in the prior art, the output end, that is, the working end, moves in a circular swing within a certain angle range, and the power source is a motor with a stator and a rotor, and the rotor also has a rotating shaft. There is at least one bearing at the front and rear of the rotary shaft as support, and a fan for cooling is installed on the motor. The multi-function machine drives the pendulum rod to swing around the output shaft through the eccentric shaft and the bearing installed on it, and the pendulum rod and the output shaft are fixed, so that the output shaft rotates in a reciprocating circle with the pendulum rod, and the working head is fixed to the output shaft. When the output shaft rotates in a reciprocating circle, the working head swings back and forth under the drive of the output shaft.
由上可知,现有技术中的多功能机,采用电机作为动力源来实现输出轴的往复摆动。但是采用电机驱动会增加整机的长度,当在狭小空间进行使用时由于机身尺寸影响,导致使用受限。而且,多功能机的电机的直径决定了握持部截面的最小周向,握持部尺寸过大,带着影响握持舒适性。多功能机的电机的重量占了整机重量的近一半,导致整机重量大,长时间使用导致操作者受累。电机在运转过程中的发热、噪音(主要是电机冷却风扇)、振动(转子不平衡量、风扇晃动、偏心结构的不平衡力等导致),影响操作者的使用舒适性。采用电机就需要通过偏心轴轴承实现输出轴的往复圆周摆动, 但是在摆动过程中偏心轴轴承受冲击力大,容易失效。As can be seen from the above, in the multifunctional machine in the prior art, the motor is used as the power source to realize the reciprocating swing of the output shaft. However, the use of motor drive will increase the length of the whole machine, and when it is used in a small space, the use is limited due to the influence of the size of the body. Moreover, the diameter of the motor of the multifunctional machine determines the minimum circumferential direction of the cross-section of the grip portion, and the size of the grip portion is too large, which affects the comfort of grip. The weight of the motor of the multi-function machine accounts for nearly half of the weight of the whole machine, which leads to the heavy weight of the whole machine, and the long-term use will cause the operator to suffer. During the operation of the motor, the heat, noise (mainly the motor cooling fan), and vibration (caused by the unbalance of the rotor, the shaking of the fan, the unbalanced force of the eccentric structure, etc.) affect the comfort of the operator. When the motor is used, the reciprocating circular swing of the output shaft needs to be realized through the eccentric shaft bearing, but the eccentric shaft bearing is subject to a large impact force during the swinging process and is prone to failure.
发明内容SUMMARY OF THE INVENTION
本发明要解决的技术问题是为了克服现有技术中的多功能机采用电机驱动导致的使用空间受限、影响操作舒适性等的缺陷,提供一种无传统定、转子电机的多功能机。The technical problem to be solved by the present invention is to provide a multi-function machine without traditional stator and rotor motors in order to overcome the defects of limited use space and influence on operation comfort caused by the motor-driven multi-function machine in the prior art.
本发明是通过下述技术方案来解决上述技术问题:The present invention solves the above-mentioned technical problems through the following technical solutions:
一种无传统定、转子电机的多功能机,其特点在于,其包括:A multifunctional machine without traditional stator and rotor motors is characterized in that it includes:
摆动机构;swing mechanism;
永磁体,所述永磁体固定于所述摆动机构的一端;a permanent magnet, which is fixed to one end of the swing mechanism;
电磁驱动机构,所述电磁驱动机构上的磁极与所述永磁体的至少一个磁极相对设置,通过改变所述电磁驱动机构的磁极的极性,驱动所述永磁体沿着远离或者靠近所述电磁驱动机构的磁极的方向移动,以实现所述摆动机构的另一端的摆动。Electromagnetic drive mechanism, the magnetic pole on the electromagnetic drive mechanism is arranged opposite at least one magnetic pole of the permanent magnet, and by changing the polarity of the magnetic pole of the electromagnetic drive mechanism, the permanent magnet is driven to move away from or close to the electromagnetic The direction of the magnetic pole of the driving mechanism is moved to realize the swing of the other end of the swing mechanism.
在本方案中,通过改变电磁驱动机构的磁极的极性,使得电磁驱动机构的磁极的极性在与永磁体的极性相同或者相异之间切换,进而使得当电磁驱动机构的磁极的极性与永磁体的极性相同时,电磁驱动机构对永磁体产生斥力,使得永磁体向远离电磁驱动机构的方向移动;当电磁驱动机构的磁极的极性与永磁体的极性相异时,电磁驱动机构对永磁体产生吸力,使得永磁体向靠近电磁驱动机构的方向移动。永磁体与摆动机构固定,永磁体在移动过程中会带动摆动机构的端部一起向靠近或者远离电磁驱动机构的方向移动,摆动机构的另一端在摆动机构朝向永磁体的一端的驱动下进行摆动。In this solution, by changing the polarity of the magnetic pole of the electromagnetic drive mechanism, the polarity of the magnetic pole of the electromagnetic drive mechanism is switched between the same or different from that of the permanent magnet, so that when the polarity of the magnetic pole of the electromagnetic drive mechanism is changed When the polarity is the same as the polarity of the permanent magnet, the electromagnetic drive mechanism repulses the permanent magnet, so that the permanent magnet moves away from the electromagnetic drive mechanism; when the polarity of the magnetic pole of the electromagnetic drive mechanism is different from that of the permanent magnet, The electromagnetic drive mechanism generates a suction force on the permanent magnet, so that the permanent magnet moves in a direction close to the electromagnetic drive mechanism. The permanent magnet is fixed with the swinging mechanism. During the movement, the permanent magnet will drive the end of the swinging mechanism to move toward or away from the electromagnetic drive mechanism. The other end of the swinging mechanism swings under the drive of the swinging mechanism toward the end of the permanent magnet. .
通过以上的结构及原理,使得多功能机中不需要设置传统的带转子和定子的电机对摆动机构进行驱动,进而实现多功能机在无传统电机的情况进行运转。在多功能机中取消传统电机以后,其机身的尺寸不再受限于电机的尺寸大小的影响,进而可减小整机长度,从而使得多功能机能适用于更为狭小 的操作空间,并且减小了握持部位的最小外周长同时也能减轻整机的重量,从而提高了操作者握持及操作的舒适性。不使用传统电机驱动就不需要设置冷却风扇对电机进行冷却,不仅没有风扇转动引起的噪音,而且也不会有风扇、转子等转动引起的振动及不平衡等现象发生,从而提高了使用者使用的舒适性。而且相对于传统的电机驱动来说,采用电磁驱动机构对多功能机进行驱动,将电能转换为机械能,减少了常规多功能机中的中间传动(偏心轴轴承驱动)、以电机自身发热等引起的损耗,使得能好更小,节省能源。Through the above structure and principle, it is unnecessary to install a traditional motor with a rotor and a stator to drive the swing mechanism in the multifunctional machine, so that the multifunctional machine can be operated without a traditional motor. After the traditional motor is cancelled in the multi-function machine, the size of the body is no longer limited by the size of the motor, and the length of the whole machine can be reduced, so that the multi-function function is suitable for a narrower operating space, and The minimum outer circumference of the holding part is reduced, and the weight of the whole machine can also be reduced, thereby improving the comfort of the operator to hold and operate. There is no need to set up a cooling fan to cool the motor without using the traditional motor drive, not only there is no noise caused by the rotation of the fan, but also there will be no vibration and imbalance caused by the rotation of the fan and rotor, thus improving the user's use. of comfort. Moreover, compared with the traditional motor drive, the electromagnetic drive mechanism is used to drive the multi-function machine, converting electrical energy into mechanical energy, reducing the intermediate transmission (eccentric shaft bearing drive) in the conventional multi-function machine, caused by the self-heating of the motor, etc. The loss makes the energy better and smaller and saves energy.
