Introduction to Power Tools:
Power tools refer to tools that are held and operated by hand, use low-power motors or electromagnets as power, and drive the working head through the transmission mechanism.
Merit:
Power tools have the advantages of easy to carry, simple operation, diverse functions, etc., can greatly reduce labor intensity, improve work efficiency, realize manual operation mechanization, so they are widely used in construction, housing decoration, automobiles, machinery, electricity, bridges, gardening and other fields, and a large number of into the family.
Peculiarity:
Power tools are characterized by light structure, small size, light weight, low vibration, low noise, flexible operation, easy to control and operate, easy to carry and use, strong and durable. Compared with hand tools, labor productivity can be increased several times to tens of times; It is more efficient than pneumatic tools, low cost and easy to control.
What are the power tool accessories:
Rotor, stator, gear, bearing, switch, carbon brush, carbon brush holder, carbon brush cover.
What power tools include:
1. Electric drill: tools for drilling metal materials, plastics and other holes. When equipped with forward and reverse switch and electronic speed control device, it can be used as an electric screwdriver. Some models are equipped with rechargeable batteries.
2. Electric hammer: used for masonry, concrete, artificial or natural stone and other drilling, and the function of electric drill is interchangeable. Light drills widely use SDS-PLUS drill chucks and drill bits, medium and heavy hammer drills are replaced with SDS-MAX chucks and drill bits and can clamp chisels.
3. Impact drilling: mainly used for power tools for drilling hard materials such as masonry and concrete. When the impact mechanism is closed, it can also be used as a normal electric drill. 4. Grinder: a tool for grinding with a grinding wheel or grinding disc for grinding wood. There are straight electric grinders and electric angular grinders. Sandpaper is required. 5. Jig saw: mainly used for cutting steel, wood, plastic and other materials, saw blade up and down reciprocating or swinging, most suitable for cutting accurate straight lines or curves. 6. Angle grinder: also known as grinding machine or disc grinder, mainly used for grinding steel, metal and stone. Commonly used grinding blade diameters are 100mm, 125mm, 180mm, 230mm.
7. Cutting machine: mainly used to cut different angles of aluminum, wood, etc., divided into metal material cutting machine and non-metal material cutting machine, pay attention to the tight saw blade when using, wear goggles.
8. Electric wrench and electric screwdriver: Electric wrench and electric screwdriver are used to load and unload threaded connectors. The transmission mechanism of the electric wrench is composed of a planetary gear and a ball screw groove impact mechanism. The electric screwdriver adopts a tooth-embedded clutch transmission mechanism or a gear transmission mechanism.
9. Concrete vibrator: used to pound concrete when pouring concrete foundation and reinforced concrete components. Among them, the high-frequency disturbance power of the electric direct vibrator is formed by the motor driving the eccentric block to rotate, and the motor is powered by a 150Hz or 200Hz intermediate frequency power supply.
10. Electric planer: used for planing wood or wood structure parts, installed on the bench can also be used as a small planer. The knife shaft of the electric planer is driven by a belt by the motor shaft.
11. Marble machine: generally cutting stone, you can choose dry or wet cutting, commonly used saw blades are: dry saw blade, wet saw blade, dry and wet saw blade. Home improvement is used to cut wall and floor tiles.
