Abstract
The invention relates to a hand-held electric drill. A main shaft is fixedly installed on a drill body, a flywheel and a driven bevel gear are fixedly installed on the main shaft respectively, a motor is fixedly installed in the drill body, the axis of the motor is vertical to the axis of the main shaft, an electromagnetic clutch is installed on a motor shaft of the motor, the upper portion of the electromagnetic clutch is fixedly connected with a drive shaft, a drive bevel gear is fixedly installed on the drive shaft and the driven bevel gear and the drive bevel gear are connected in a fit mode. Under the condition that the drilling starts or the load increases suddenly, the drilling is conducted normally, the motor is not damaged, the working state of the drill can stop immediately under the critical condition, and the construction safety is greatly improved.
Description
Technical field
The present invention relates to the electric tool technical field, is a kind of hand held electric drill specifically.
Background technology
At present, although 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, in 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, easy motor damage also; In addition; in the hand held electric drill of this class formation; driving-chain between from the motor to the drill bit is 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 in the situation of High Rotation Speed; in case meet at work critical situation; especially in the situation that cutter blocks; must realize as early as possible shutting down, because the rotor of motor has stored certain energy; although motor is cut off the electricity supply; 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 invention provides a kind of hand held electric drill, 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 thus scarce limit of the easy motor damage of initiation; Simultaneously, also in order to overcome existing all existence of hand held electric drill: in critical situation, can't stop immediately the duty of electric hand drill, and the danger that causes therefrom.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: this invention comprises the brill body, main shaft, passive bevel gear, driving shaft, driving bevel gear, electromagnetic clutch, motor, flywheel, be installed with main shaft with it at brill, on main shaft, be installed with respectively flywheel and passive bevel gear, be installed with motor in the inside of boring body, the axis of motor and the axis of main shaft are perpendicular, on the motor shaft of motor, electromagnetic clutch is installed, top and the driving shaft of electromagnetic clutch are connected to a fixed, driving bevel gear be fixedly installed in driving shaft above, and driving bevel gear is connected with passive bevel gear joint match.
Beneficial effect of the present invention: though the present invention drilling begin or the unexpected increase situation of loading under, also normally drilling, and can not cause burn-down of electric motor, and in critical situation, can stop immediately the duty of electric hand drill has greatly improved construction safety.
Description of drawings
Accompanying drawing 1 is structure principle chart of the present invention.
Shown in the figure: 1, bore body; 2, main shaft; 3, passive bevel gear; 4, driving shaft; 5, driving bevel gear; 6, electromagnetic clutch; 7, motor; 8, flywheel.
The specific embodiment
In the drawings, this invention comprises bores body 1, main shaft 2, passive bevel gear 3, driving shaft 4, driving bevel gear 5, electromagnetic clutch 6, motor 7, flywheel 8, be installed with main shaft 2 at brill body 1, on main shaft 2, be installed with respectively flywheel 8 and passive bevel gear 3, be installed with motor 7 in the inside of boring body 1, the axis of the axis of motor 7 and main shaft 2 is perpendicular, electromagnetic clutch 6 is installed on the motor shaft of motor 7, the top of electromagnetic clutch 6 and driving shaft 4 are connected to a fixed, driving bevel gear 5 be fixedly installed in driving shaft 4 above, and driving bevel gear 5 is connected with passive bevel gear 3 joint matchs.Even the present invention drilling begin or the unexpected increase situation of loading under, also normally drilling, and can not cause burn-down of electric motor, and in critical situation, can stop immediately the duty of electric hand drill has greatly improved construction safety.
