Abstract
The utility model discloses an electric cutting tool which comprises the following components: a brushless motor, a chassis mechanism, a frame and a cutting mechanism. The motor is provided with the brushless motor. The chassis mechanism is provided below the frame. The electric cutting tool comprises a cutting disc and a lower cutter, wherein the lower cutter is provided on the chassis mechanism. The electric cutting tool is characterized in that: the frame is provided with a shaft hole and a motor mounting hole; the brushless motor is fixed on the frame through the motor mounting hole; a rotor shaft of the brushless motor projects from a disc of the frame; and the cutting disc in the cutting mechanism is directly equipped on the rotor shaft of the brushless motor. The electric cutting tool greatly simplifies mechanism structure of the electric cutting tool and furthermore utilizes electronic control technology of the brushless motor for facilitating the use of the electric cutting tool. Furthermore the electric cutting tool has the following advantages: low noise, small vibration, no easy abrasion, no requirement for frequent adding of lubricating oil, and improved market competitiveness of the product.
Description
Technical field
The utility model relates to a kind of electronic shearing knife, refers more particularly to a kind of portable miniature electric shearing knife.
Technical background
The electronic shearing knife of using in the market is to utilize the high speed brush motor to rotate the cutting cloth through worm screw, the direct driving blade of worm gear, and this electronic shearing knife has following defective: motor speed is high, and noise is big; Vibration is big; Easy abrasion, necessary often apply oil, and worm and gear is a core part; Assembly technology is complicated, and is pretty troublesome during replacing.For this problem; Chinese invention patent 200910095605.2 discloses a kind of technical scheme of electronic shearing knife; Its content is: " a kind of electronic shearing knife, it comprises motor frame, body chassis, frame, electronic shearing knife structure, and brushless electric machine and drive pulley gear are housed on the said motor frame; said drive pulley gear comprises one group of drive and driving belt at least, driving belt transmission drive drives the blade rotation.Said drive is synchronizing wheel or belt pulley or articulated gear.Said driving belt is to be with synchronously or belt or chain.Said drive pulley gear is through drive number of teeth speed change or through diameter pulley size speed change.Said motor frame and the space that the cutting fabric thickness is arranged after the height that the blade rotation is arranged after frame is connected and the blade shaft other end are installed drive.Yet ", obviously also there is following defective in the enforcement of this technical scheme: one of which, motor are installed on the frame, through the belt pulley transferring power, make whole mechanical structure seem very heavy; Its two, the rotating speed of blade relies on drive number of teeth speed change or adjusts through the diameter pulley size, makes its very inconvenience in the use.
The utility model content
The purpose of the utility model provides and a kind of cutting disc directly is installed on the motor, and utilizes electromechanical integration technology, realizes the cutting machine of brushless electric machine low speed, the output of high torque power, is able to solve the defective of existing electric (al) cutter.
The purpose of the utility model realizes through following technical scheme: a kind of electronic shearing knife; It comprises brushless electric machine, body chassis, frame, cutting mechanism, on the described frame brushless electric machine is housed, the bottom installation chassis mechanism of frame; Described cutting mechanism comprises cutting disc and following cutter; Wherein descend cutter to be installed on the body chassis, it is characterized in that described frame is provided with axis hole and motor installing hole, brushless electric machine is fixed on the frame through the motor installing hole; Its rotor roller protrudes in the frame disc, and the cutting disc in the cutting mechanism directly is installed on the armature spindle of brushless electric machine.
Described frame upper end is provided with control box, and the circuit board and the gauge tap of brushless electric machine is installed in it, and circuit board and gauge tap are connected with brushless electric machine through power control line.
The beneficial effect of the utility model is: cutting disc directly is installed on the armature spindle of brushless electric machine; Its rotating speed can like this, not only have been simplified the mechanism structure of electric (al) cutter greatly through the electronics adjustment; And utilize the electron controls technology of brushless electric machine; Make the use of electronic shearing knife also become very convenient, and noise of equipment equipment is low, the vibration is little, not easy to wear, also frequent apply oil, has strengthened product market competitiveness.
