Abstract
The invention discloses a structure of a hand-held type electric drill, wherein a main shaft is installed on a drilling machine; simultaneously, a driven bevel gear is installed at the right end of the main shaft, a motor is installed in the drilling machine, the axis of the motor is vertical to the axis of the main shaft, a flywheel is installed on a motor shaft at the lower part of the motor, an electromagnetic clutch is installed on an output shaft at the upper part of the motor, the upper part of the electromagnetic clutch is connected with a drive shaft, and a drive bevel gear is installed on the drive shaft, so that the drive bevel gear forms is matched with the driven bevel gear.
Description
Technical field
The present invention relates to a kind of structure of electric drill, particularly a kind of structure of hand held electric drill belongs to the electric tool technical field.
Background technology
At present, although the hand held electric drill structurally is not quite similar,, basic structure all is to rotate the purpose that realizes drilling by motor through the direct driving main shaft of transmission system, drill bit.Such electric hand drill is directly provided by motor owing to energy; Under the situation that drilling begins or load increases suddenly in drilling, the instantaneous load of motor is increased, drilling can't normally be gone on; Simultaneously, also burn motor easily; In addition, in the hand held electric drill of this class formation, the driving-chain between from the motor to the drill bit is a rigidity; The beginning of drill bit work is controlled with stopping to accomplish by the start-stop of motor, because the rotor of motor has stored certain energy under the situation of rotation at a high speed, so; In case meet critical situation at work, under the situation that especially cutter blocks, must realize as early as possible shutting down; Though cut off the electricity supply because the rotor of motor has stored the certain energy motor,, under the effect of inertia force; Still have certain moment of torsion and be delivered to drill bit, so, still there is certain danger.
Summary of the invention
The objective of the invention is to: a kind of structure of hand held electric drill is provided, and it is existing to overcome existing hand held electric drill, drilling begin or the situation about increasing suddenly of load under, normally drilling and the scarce limit of burning motor easily of initiation thus; Simultaneously, also in order to overcome existing all existence of hand held electric drill: under critical situation, can't stop the duty of electric hand drill immediately, and the danger that causes therefrom.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: a kind of structure of hand held electric drill, and it is that main shaft is installed on drilling machine, simultaneously; Passive bevel gear is installed in the right-hand member of main shaft; In the inside of drilling machine one motor is installed, the axis of motor and the axis of main shaft are perpendicular, and a flywheel is installed on the motor shaft of motor lower portion; One electromagnetic clutch is installed on the output shaft on motor top; The top of electromagnetic clutch connects with driving shaft mutually, and driving bevel gear is installed on the driving shaft, makes driving bevel gear and passive bevel gear form identical.
Beneficial effect: the present invention is owing to adopt technique scheme, so it is existing to overcome existing hand held electric drill, drilling begin or the situation about increasing suddenly of load under, normally drilling and the scarce limit of burning motor easily of initiation thus; Simultaneously, also overcome all existence of existing hand held electric drill: under critical situation, can't stop the duty of electric hand drill immediately, and the defective of initiation potential therefrom.
Description of drawings
Below in conjunction with accompanying drawing structure of the present invention is described further;
Fig. 1 is a structure principle chart of the present invention;
Shown in the figure: 1, drilling machine; 2, main shaft; 3, passive bevel gear; 4, driving shaft; 5, driving bevel gear; 6, electromagnetic clutch; 7, motor; 8, flywheel; 9, electric drill body.
The specific embodiment
The structure of hand held electric drill has a drilling machine 1, main shaft 2 is installed, simultaneously on drilling machine 1; Passive bevel gear 3 is installed in the right-hand member of main shaft 2; In the inside of drilling machine 1 motor 7 is installed, the axis of the axis of motor 7 and main shaft 2 is perpendicular, and a flywheel 8 is installed on the motor shaft of motor 7 bottoms; One electromagnetic clutch 6 is installed on the output shaft on motor top; The top of electromagnetic clutch 6 connects with driving shaft 4 mutually, and driving bevel gear 3 is installed on the driving shaft 4, driving bevel gear 5 is formed with passive bevel gear 3 coincide.
