Electric screwdriver solution
An electric screwdriver, also known as an electric batch or an electric screwdriver, is an electric tool for tightening and loosening screws. Equipped with a mechanism for adjusting and limiting torque, this electric tool is mainly used in assembly lines and is one of the necessary tools for most production companies.
Electric screwdriver solution principle
As a mechanical component, the electric screwdriver cannot work without the electric batch power supply, which provides energy and related control functions for the electric screwdriver. Drive the rotation of the motor. Due to the different parameters of the electric screwdriver motor, the speed will be different when the electric batch power output is the same. Electric screwdrivers are divided into three categories: straight rod type, hand-held type, and installation type.
Features of electric screwdriver solution
The electric screwdriver is completely designed according to ergonomics, and its product quality must meet the national standard of the People's Republic of China for electric screwdrivers GBT 22679-2008.
1. Light weight and small size.
2. Power supply mode: safe low-voltage power supply, the batch head is grounded to prevent static electricity.
3. Torque accuracy ±3%, speed control (high speed and low speed).
4. There are a variety of switch methods available: push/slide/press switch, lever start.
5. There are carbon brushes and no carbon brushes, and there are automatic alarm signals.
The difference between electric screwdriver and electric drill
1. The electric drill is a hole, and the electric screwdriver is a self-tapping screwdriver. The electric drill is a drilling tool that uses electricity as power.
2. The main specifications of the electric drill are 4, 6, 8, 10, 13, 16, 19, 23, 32, 38, 49mm, etc. The number refers to the maximum diameter of the drill bit for drilling on steel with a tensile strength of 390Nmm2. For non-ferrous metals, plastics and other materials, the maximum drilling diameter can be 30-50% larger than the original specification.
How to use an electric screwdriver
1. Preparation work before using electric batch
Check whether the voltage is normal, then equip a screwdriver head according to the shape of the locked screw, and then adjust the torque of the locked product.
2. Operation steps of electric screwdriver
(1) When connecting or removing the screwdriver bit, push the screwdriver cap up with your fingertips.
(2) Plug in the power supply and set the switch to the "F" position, install the screwdriver head, and pre-adjust the position of the torque section required for locking the screw.
(3) Press the switch by hand to start the machine, press the trigger to pull it in its own direction, then the switch will be turned "ON" to start the motor, and start to operate the lock screw. When the screw lock exceeds the set torque, the clutch will slip automatically, the screwdriver head stops rotating, and the operation is completed.
(4) When the hand presses the switch plate and releases it, the power of the screwdriver will be turned off, and the motor will stop working. Repeated operations can continue to be used. If the screw is to be loosened, the switch should be placed in the "R" position, and the operation can be completed according to the above operations. .
(5) The adjustment torque is adjusted by the torque adjustment ring at the bottom. The number of segments of the fuselage itself does not represent the output torque value, which is indicated by the torque table.
(6) The screwdriver head adjusts the relationship between the number of torque segments and its own output torque.
