Abstract
The utility model relates to a structure of a novel hand-held electric drill, comprising a drilling machine, a main shaft, a driven bevel gear, a driving shaft, a driving bevel gear, an electromagnetic clutch, a motor and a fly wheel. The hand-held electric drill is provided with the drilling machine on which the main shaft is installed; meanwhile, the driven bevel gear is installed at the right end of the main shaft, the motor is installed at the inner part of the drilling machine, the axis of the motor is vertical to that of the main shaft, the fly wheel is installed on a motor shaft at lower part of the motor, the electromagnetic clutch is installed on an output shaft at the upper part of the motor, and the upper part of the electromagnetic clutch is connected with the driving shaft on which the driving bevel gear is installed, so as to lead the driving bevel gear to be inosculated with the driven bevel gear.
Description
Technical field
The utility model relates to a kind of structure of electric drill, and particularly a kind of structure of novel 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 drive shaft of transmission system, drill bit.The electric hand drill of this kinds of structures 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; driving-chain between from the motor to the drill bit is a rigidity; the beginning of drill bit work is controlled by the start-stop of motor with stopping to finish; 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, especially under the situation that cutter blocks, must realize as early as possible shutting down; because the rotor of motor has stored certain energy; though motor is cut off the electricity supply; but, under the effect of inertia force, still have certain moment of torsion and be delivered to drill bit; so, still have certain danger.
The utility model content
The purpose of this utility model is: a kind of structure of novel 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 utility model realizes that the technical scheme that above-mentioned purpose adopted is: a kind of structure of novel hand held electric drill, and it is made up of drilling machine, main shaft, passive bevel gear, driving shaft, driving bevel gear, electromagnetic clutch, motor, flywheel; The structure of hand held electric drill has a drilling machine, main shaft is installed on drilling machine, simultaneously, passive bevel gear is installed in the right-hand member of main shaft, one motor is installed in the inside of drilling machine, the axis of motor and the axis of main shaft are perpendicular, one flywheel is installed on the motor shaft of motor lower portion, an electromagnetic clutch is installed on the output shaft on motor top, the top of electromagnetic clutch connects mutually with driving shaft, driving bevel gear is installed on the driving shaft, makes driving bevel gear and passive bevel gear form identical.
Beneficial effect: the utility model 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.
