Detailed description of the invention
Please refer to Fig. 1, an embodiment provides a kind of sander 100.This sander 100 comprises shell 110, the motor be arranged in shell 110, to be connected and to be driven the emery disc 130 rotating and carry out polishing operation by motor with motor.The fan 140 sander 100 being cooled and siphoned away the dust that sander 100 work produces also is provided with in the shell 110 of this sander 100.The shell 110 of this sander 100 is provided with power line 114 and switch 112, and power line 114 and external power source are connected to this sander 100 and provide electric power needed for work, and switch 112 is used for controlling opening and cut out of this sander 100.The emery disc 130 of this sander 100 comprises interior emery disc 131 and outer emery disc 132, and motor output shaft 125 drives interior emery disc 131 to rotate by interior emery disc eccentric shaft 133, and drives outer emery disc 132 to rotate by outer emery disc eccentric shaft 134.Interior emery disc eccentric shaft 133 and outer emery disc eccentric shaft 134 are fixed on motor output shaft 125 and by the position-limiting action of bearing 150 and drive interior emery disc 131 and outer emery disc 132 to rotate.The shell 110 of sander 100 is also provided with the dust catcher interface 160 be connected with outside dust catcher.Outside dust catcher can be siphoned away by this dust catcher interface 160 dust produced that to be worked by this sander 100, like this relative to adopting the fan 140 of sander 100 self to carry out dust suction, can reach better pick-up performance.
The motor of this sander 100 is motor in axial magnetic field.Motor in axial magnetic field is also disc motor.Its main field is along motor output shaft 125 direction.Motor in axial magnetic field has flat outer shape, and like this, the appearance profile of this sander 100 can be reduced, thus makes the palm of operator more close to working face, namely close to emery disc 130.Handled easily person the polishing position of emery disc 130 can be accurately controlled when the palm distance emery disc 130 of operator is nearer.
In addition, the design that motor in axial magnetic field is general does not have stator core, but adopts magnet steel to replace stator core.Motor in axial magnetic field does not have silicon steel sheet yet, and the size and Orientation in magnetic field is fixed.When motor in axial magnetic field adopts brushless electric machine, motor in axial magnetic field does not have commutation spark and iron loss, and product energy efficiency improves.And the characteristic of motor in axial magnetic field is hard, still keeps the performance of high energy conversion rate, do not need speed stabilizing just can reach the effect of speed stabilizing under high moment of torsion, this will be conducive to the work of the sander 100 adopting motor in axial magnetic field.
The motor in axial magnetic field that the motor of this sander 100 adopts also can be able to be brushless electric machine for brush motor.Below by introduce respectively motor in axial magnetic field that this sander 100 adopts be brush motor and brushless electric machine time structure.
The concrete structure of motor in axial magnetic field when being brush motor by the motor in axial magnetic field of introducing this sander 100 in detail below.Please refer to Fig. 2 and Fig. 3, herein, the motor in axial magnetic field that this sander 100 adopts is brush motor.This motor in axial magnetic field comprises motor casing 121, the magnet steel 122 be arranged in motor casing 121, the carbon brush 123 be arranged in motor casing 121, the commutator 124 be arranged in motor casing 121, be arranged at coil 126 in motor casing 121 and rotate the motor output shaft 125 be fixed on motor casing 121.Motor output shaft 125 is rotated by the bearing 150 be fixed on motor casing 121 and is fixed on motor casing 121.The coil 126 of this motor in axial magnetic field to be fixed on motor output shaft 125 and to rotate together with motor output shaft 125.Magnet steel 122 is fixed on motor casing 121, and carbon brush 123 is by current lead-ins circle 126, and commutator 124 controls the direction of rotation of motor output shaft 125.Further, the wire that coil 126 uses herein is enamel-covered wire, is also provided with every electroplax 127 in motor casing 121, and the security of this motor in axial magnetic field is improved like this.When being installed on this sander 100 by this motor in axial magnetic field, the motor output shaft 125 of this motor in axial magnetic field just can drive interior emery disc 131 to rotate by interior emery disc eccentric shaft 133, and drives outer emery disc 132 to rotate by outer emery disc eccentric shaft 134.
Because the appearance profile of this motor in axial magnetic field is flat shape relative to radial magnetic field motor, therefore the appearance profile of sander 100 can be reduced when this motor in axial magnetic field is installed on this sander 100, namely reduce the height of sander 100, make the palm of operator more close to emery disc 130.Like this, operator more accurately can control the polishing position of emery disc 130.
Certainly, this sander 100 also can adopt brushless electric machine.Institute's employing brushless electric machine is also motor in axial magnetic field.The concrete structure of motor in axial magnetic field when being brushless electric machine by the motor in axial magnetic field of introducing this sander 100 in detail below.Please refer to Fig. 4, herein, the motor in axial magnetic field that this sander 100 adopts is brushless electric machine.This motor in axial magnetic field comprises motor casing 121, the magnet steel 122 be arranged in motor casing 121, be arranged at coil 126 in motor casing 121 and rotate the motor output shaft 125 be fixed on motor casing 121.Motor output shaft 125 is rotated by the bearing 150 be fixed on motor casing 121 and is fixed on motor casing 121.Magnet steel 122 to be fixed on motor output shaft 125 and to rotate together with motor output shaft 125, and coil 126 is fixed on motor casing 121.Herein, the wire that coil 126 uses is enamel-covered wire.In addition, the motor casing 121 of this motor in axial magnetic field can be metal chassis also can be cabinet, and the rotor be made up of coil 126 grade can be Full-plastics sealed rotor.When being installed on this sander 100 by this motor in axial magnetic field, the motor output shaft 125 of this motor in axial magnetic field just can drive interior emery disc 131 to rotate by interior emery disc eccentric shaft 133, and drives outer emery disc 132 to rotate by outer emery disc eccentric shaft 134.
Identical with brush motor, also can reduce the appearance profile of sander 100 when this motor in axial magnetic field is installed on this sander 100, make the palm of operator more close to emery disc 130.Like this, operator more accurately can control the polishing position of emery disc 130.
The motor of this sander adopts motor in axial magnetic field.Because motor in axial magnetic field has flat outer shape, the appearance profile of this sander can be reduced, thus makes the palm of operator more close to working face, namely close to emery disc.Like this, the palm distance emery disc of operator is comparatively near, thus handled easily person accurately controls the polishing position of emery disc, makes more convenient operation.
The above embodiment only have expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
