Power tools electric, power tool

A mechanical tool powered by an electric motor or electromagnet and driven by a drive mechanism.

Electric tool

Operated by hand, a small power motor or electromagnet is used as the power to drive the work head by means of a drive mechanism. Power tools are mainly divided into metal cutting, power tools, grinding power tools, assembly of power tools and railway power tools. Common electric tools electric drill, electric grinder, electric wrench and electric screwdriver and hammer, impact drill, concrete vibrator, planer.

Electric drill: the main specifications are 4, 6, 8, 10, 13, 19, 16, 23, 32, 38, 49mm and so on. Figures refer to the maximum diameter of the drill drilled on the steel whose tensile strength is 390N/mm. For non-ferrous metals, plastics and other materials, the maximum drilling diameter is comparable to the original specifications of 30 to 50%.

Electric grinding machine: a tool for grinding with a grinding wheel or millstone. A vertical electric wheel and electric angle grinder.

Electric wrench and electric screwdriver: used for loading and unloading threaded fittings. The driving mechanism of the electric wrench is composed of a planetary gear and a ball screw groove impact mechanism. Specifications are M8, M12, M16, M20, M24, M30 and so on. The electric screwdriver adopts the embedded clutch, transmission mechanism or gear drive mechanism. The specifications include M1, M2, M3, M4, M6 and so on.

The hammer and drill: used for concrete, brick and building components on drilling, slotting, dehairing. With the use of expansion bolts, the installation speed and quality of various pipelines and machine tools can be improved.

Concrete vibrator: used for pouring concrete foundation and reinforced concrete members, tamping concrete to eliminate air holes and increase strength. The high-frequency disturbing power of the electric direct acting vibrator is driven by an electric motor to rotate the eccentric block, and the motor is powered by an 150Hz or 200Hz intermediate frequency power supply.

The wood planer: used for planing wood or wood structure, mounted on the bench can be used as a small bench plane. The planer cutter shaft by the motor shaft through the belt drive.
