Abstract
The utility model discloses a rotating speed controller for a gun drill, comprising a gun drill driving motor (M). The gun drill driving motor (M) is powered by a silicon controlled rectifier voltage regulating circuit, and the silicon controlled rectifier voltage regulating circuit is composed of a silicon controlled rectifier (AGK), a first resistor (R1), a variable resistor (R2), a resistance divider (R3), a capacitor (C1) and a bidirectional diode (D). A voltage is applied over the first resistor (R1), adjusted for output by the variable resistor (R2) and the resistance divider (R3), and supplied to the gun drill driving motor (M) by the silicon controlled rectifier (AGK) via the bidirectional diode (D). The rotating speed controller enables the operator to freely adjust the rotating speed of the gun drill according to the requirements of customers, such that the gun drill can adapt to various working environments. The rotating speed controller can also control the start and stop of the gun drill, and can be conveniently fixed on the gun drill.
Description
Technical field:
The utility model relates to the used rotational speed governor of a kind of power drill.
Background technology:
Existing power drill generally only opens or closes two kinds of states, when power drill is opened, can hole, and when power drill was closed, power drill just quit work.Its weak point is: because the operational environment of power drill is different with occasion, need to control the rotating speed of power drill sometimes, and general power drill is uncontrollable.
The utility model content:
The purpose of this utility model is exactly the deficiency at prior art, and a kind of power drill rotational speed governor is provided, and it can by user's free adjustment power drill rotating speed, adapt to various working environments to satisfy power drill by customer demand.
Technology solution of the present utility model is as follows:
The power drill rotational speed governor, comprise the power drill drive motors, the silicon-controlled voltage regulation circuit is given the power supply of power drill drive motors, the silicon-controlled voltage regulation circuit is made up of controllable silicon, first resistance, variable resistor, divider resistance, electric capacity and bidirectional diode, voltage is behind first resistance, regulate the voltage of exporting through variable resistor and divider resistance again, behind bidirectional diode, give the power supply of power drill drive motors by controllable silicon again.
Described controllable silicon, first resistance, variable resistor, divider resistance, electric capacity and bidirectional diode printing are in the circuit board.
The beneficial effects of the utility model are:
It can by user's free adjustment power drill rotating speed, adapt to various working environments to satisfy power drill by customer demand, can also allow the pistol electric drill open or close.It can also allow people very easily the utility model is fixed on the power drill.
Description of drawings:
Fig. 1 is structural representation of the present utility model
Embodiment:
Embodiment: see shown in Figure 1, the power drill rotational speed governor, comprise power drill drive motors M, the silicon-controlled voltage regulation circuit is given power drill drive motors M power supply, the silicon-controlled voltage regulation circuit is made up of controllable silicon AGK, first resistance R 1, variable resistor R3, divider resistance R3, capacitor C 1 and bidirectional diode D, voltage is regulated the voltage of exporting through variable resistor R2 and divider resistance R3 again after first resistance R 1, give power drill drive motors M power supply by controllable silicon AGK again behind bidirectional diode D.
Described controllable silicon AGK, first resistance R 1, variable resistor R3, divider resistance R3, capacitor C 1 and bidirectional diode D are printed on the wiring board 1.
Operation principle: voltage is regulated the voltage of exporting through variable resistor R2 and divider resistance R3 again after first resistance R 1, give power drill drive motors M power supply by controllable silicon AGK again behind bidirectional diode D.The voltage that flows to power drill drive motors M can change from small to big, also can also can become null value from large to small, thereby realize by user's free adjustment power drill rotating speed, adapt to various working environments to satisfy power drill, can also allow the pistol electric drill open or close.
Its controllable silicon AGK, first resistance R 1, variable resistor R3, divider resistance R3, capacitor C 1 and bidirectional diode D are printed on the wiring board 1.Make controller form an integrated package, be convenient for people to the utility model is installed on the power drill very easily.
