Drilling/clamping device
View Patent ↗The invention relates to a drilling/clamping device including a base body which can be extracted from the shaft or rod, provided at one end with a drilling head actuated by means of an electric motor housed inside the base body. The base body also includes means for coupling to the shaft or rod, provided with means for actuating an electrical contactor element in order to actuate the electric motor. In addition, a rising/falling pivoted connection is provided between the coupling means and the base body, such that, when pressure is applied to the rod or shank the coupling means move axially and abut against the contactor element associated with the electric motor, thereby starting the electric motor.
1. A drilling-clamping device, comprising:
a. a base body;
b. an electric motor housed within the base body;
c. a drilling head;
d. an axle, wherein the electric motor and the drilling head are connected by the axle;
e. an electrical contactor element on a top surface of the electric motor;
f. a hollow tubular body configured to engage with the base body, wherein the hollow tubular body has a protrusion at a lower end, the protrusion being configured to engage with the electrical contactor element, and wherein an upper end of the hollow tubular body is configured to receive a shaft;
g. a battery; and
h. an electrical connection from the battery to the electric motor,
wherein the shaft, the hollow tubular body, the electric motor, the base body, and the drilling head are axially aligned, wherein application of axial pressure on the shaft is configured to connect the protrusion of the tubular body with the electrical contactor element, wherein said connection is configured to activate the electric motor and turn the axle.
2. The drilling-clamping device of claim 1 , wherein the hollow tubular body further comprises a releasable tensioning device configured to securingly engage the shaft and prevent axial or rotational movement of the shaft.
3. The drilling-clamping device of claim 1 , wherein the base body is pivotably connected to the hollow tubular element.
