Referring to fig. 1, an embodiment of the present invention includes:
a rack-driven large-opening electric shears comprising: the cutting device comprises a shell 1, wherein a connecting seat 2 connected with a power supply and a motor 3 electrically connected with the connecting seat 2 are arranged on the right side of the shell, a transmission mechanism connected with the motor 3 is arranged inside the shell 1, a cutting mechanism connected with the transmission mechanism is arranged on the left side of the shell 1, and the cutting mechanism is formed by hinging a movable blade 10 and a fixed blade 11 and is characterized in that the transmission mechanism and the cutting mechanism are connected through a driving arm 9;
the transmission mechanism includes: the gear rack assembly comprises a driving shaft 4, a gear 5 and a gear rack assembly, wherein the gear rack assembly is positioned at the bottom of the shell 1 and consists of a guide rail 7 and a gear rack 6, the gear rack 6 is slidably embedded in the guide rail 7 through a guide wheel 8, the upper surface of the gear rack 6 is meshed with the gear 6, and the gear 6 is connected with the motor 3 through the driving shaft 4;
the upper end of the driving arm 9 is fixed at the hinged position of the movable blade 10 and the fixed blade 11, the lower end of the driving arm 9 is connected with the rack 7 through the movable pin 15, and finally, the shearing between the movable blade 10 and the fixed blade 11 is realized in a gear-rack transmission mode.
Further, a hall switch 12 and a hall control panel 13 are further arranged inside the housing 1, the hall switch 12 is electrically connected with the hall control panel 13, the hall control panel 13 is electrically connected with the motor 3, when an operator presses the hall switch 12, the hall control panel 13 receives a starting signal, the motor 3 is started to operate, the cutting of the movable blade 10 is driven, when the operator releases the hall switch 12, the hall control panel 13 receives a closing signal, the motor 3 is closed, and the movable blade 10 is released and reset.
Further, the lower end of the driving arm 9 is provided with a sliding groove 14, and the movable pin 15 is slidably embedded in the sliding groove 14, so that the driving arm 9 is driven by the rack 6 to reciprocate, and the phenomenon that the driving arm 9 is damaged or broken due to the distance between the driving arm and the rack can be avoided.
Further, the left side of the driving shaft 4 is connected with the gear 5 through the conical teeth 16, and the transmission ratio between the gear 5 and the driving shaft 4 can be reduced through the conical teeth 16, so that the speed is reduced; the right side of the driving shaft 4 is connected with the motor 3 through the planetary gear carrier 17, the transmission ratio between the motor 3 and the driving shaft 4 can be reduced through the planetary gear carrier 17, the speed reduction effect is further achieved, finally, the use safety of operators is guaranteed, and meanwhile the service life of the shearing mechanism can be prolonged.
Explaining still further, the utility model discloses a rack drive formula large-opening type electric scissors, its specific theory of operation is as follows:
the operating personnel passes through connecting seat 2 switch on, and press hall switch 12, hall control panel 13 receives the opening signal that hall switch 12 sent afterwards, order about motor 3 corotation, under the effect of drive shaft 4, make gear 5 begin the forward rotation, because gear 5 meshes with rack 6 mutually, consequently can drive rack 6 and move left along guide rail 7 in the rotatory while of gear 5, again because rack 6 links to each other through removable pin 15 with actuating arm 9, consequently can drive actuating arm 9 and carry out the forward rotation when rack 6 removes, finally drive blade 10 is rotatory to stationary blade 11 under the effect of actuating arm 9, realize the cutting.
An operator loosens the hall switch 12, then the hall control panel 13 receives a closing signal sent by the hall switch 12 to drive the motor 3 to rotate reversely, under the action of the driving shaft 4, the gear 5 starts to rotate reversely, and the gear 5 is meshed with the rack 6, so that the rack 6 can be driven to move rightwards along the guide rail 7 while the gear 5 rotates, and the rack 6 is connected with the driving arm 9 through the movable pin 15, so that the driving arm 9 can be driven to rotate reversely while the rack 6 moves, and finally the movable blade 10 is driven to rotate far away from the fixed blade 11 under the action of the driving arm 9, so that resetting is realized.
Different from the prior art, the rack-driven large-opening electric scissors of the utility model can realize the left and right reciprocating motion of the rack 6 in the guide rail 7 on one hand by adopting the transmission mode of meshing the gear and the rack, the driving arm 9 is driven to move under the action of the connecting mechanism of the movable pin 15 and the sliding groove 14, and finally the movable blade 10 is driven to cut, on the other hand, compared with the traditional gear transmission mechanism, such a rack and pinion gear mechanism enables the reciprocating motion of the rack 6 to overlap with the transmission among the pinion 5, the drive shaft 4, and the motor 3 in terms of the inner space, therefore, the overall length is greatly shortened, the hand-held comfort level is improved, the driving arm 9 is matched with the movable blade 10 to be connected, the opening between the movable blade 10 and the fixed blade 11 can be enlarged as much as possible, and finally the cutting capacity is greatly improved.
It is supplementary to need, the utility model relates to a big open-type electric scissors of rack-driven formula, when outdoor nothing can external power supply, also can accomplish the cutting of shearing mechanism through the mode of built-in group battery, consequently adopt built-in group battery to realize the technical scheme of this technological effect also belongs to the utility model discloses the scope of protecting.
