  • 2020-10-29 What is an electric screwdriver? The electric screwdriver is suitable for screw connection firm or disassembly in mechanical assembly, construction and other industries. The single-phase series-excited screwdriver is composed of a single-phase series-excited motor, gear reducer, clutch device, screwdriver head and protective cover, forward and reverse power switch and power connection device. The electric screwdriver clutch device is composed of a jaw clutch, a pressure spring, an adjusting nut, and a main shaft with a screwdriver bit. The rotary motion of the screwdriver bit is decelerated by the motor through the secondary gear, and then drives the hollow shaft to rotate. The front end of the hollow shaft is the active part of the jaw clutch. After the motor is started, the hollow shaft rotates without load and the screwdriver bit is stationary. When the screwdriver bit is axially compressed, the hollow shaft spring compresses, so that the teeth on the end face of the clutch follower engage with the teeth of the clutch driver at the front end of the hollow shaft, so that the steel ball of the jaw clutch is integrated with the screwdriver bit. The screwdriver bit Also rotate together, you can tighten or remove the screws. After the jaw clutch is engaged, the torque is transmitted by the three steel balls in the middle. When working, if the required torque is reached or the torque is too large, the jaw clutch follower compresses the spring, and slips away from the driver and follower of the jaw clutch to prevent thread damage and motor overload. The adjusting nut is used to adjust the output torque of the screwdriver bit. Through the working spring, the pressing force of the follower of the jaw clutch is adjusted to ensure the smooth separation of the jaw clutch under a certain torque. The torque can be achieved by turning the adjusting nut. If the adjusting nut rotates in the direction of the jaw clutch, the spring is compressed and the transmission torque is lar

  • 2020-08-04 What does the electric screwdriver torque 3NM mean? People often ask what does the electric screwdriver torque 3NM mean? The electric screwdriver torque 3N.M means that the torque applied by the screwdriver to the tightened screw is 3 N.m. Once this torque is exceeded, the twisting head will automatically slip. This tool is generally used for precise screw fixation. Torque in physics is the magnitude of moment, equal to the product of force and moment arm, the international unit is Newton meter N*m. In physics, the tendency of a force to rotate an object around a rotation axis or fulcrum is called a torque. Torque is also called torque. Moment can cause an object to change its rotational movement. Pushing or pulling involves force, while torsion involves moment. Torque is equal to the cross product of radial vector and force. In short, a torque is a torsional force applied to objects such as bolts or flywheels. For example, tighten the bolt or nut with the opening of the wrench, and then turn the wrench. This action will generate torque to turn the bolt or nut. According to the International System of Units, the unit of torque is Newton meters. The connection quality of torque screwdriver fasteners directly affects the use quality of various instruments, electromechanical equipment, household appliances and other products to the reliability of these products. Therefore, torque tools such as torque screwdrivers are gradually being used more and more in industrial production. Functional principle of torque screwdriver: ‍The preset torque screwdriver can set the torque value in advance. When the screwed fastener reaches the predetermined torque value, the clutch inside the screwdriver will automatically disengage and send out "click, click, click... ", and you can feel this movement with your hands. At this time, even if you continue the afterburner operation, it will not exceed the preset limit.
