The difference between smart electric screwdrivers and ordinary electric screwdrivers

Ordinary electric screwdrivers and pneumatic screwdrivers are promoted by most manufacturers due to their light weight and low cost. The screw locking work of general industrial products uses electric screwdrivers or pneumatic screwdrivers, which can meet production requirements, so they are highly recognized.

The smart electric screwdriver needs to perform tasks through servo motors, PLCs, and drivers, and can run complex algorithms. Its torque control is more precise, can give torque values in real time, and perform actions according to torque reference values to complete high-standard and difficult locking work.

Briefly introduce the difference between smart electric screwdrivers and electric screwdrivers:

1. Speed: The servo motor has large output, fast response, high speed, small inertia, smooth rotation, and stable torque.

2. Precision: The servo motor can realize high-speed real-time detection and high-precision control of tightening torque value; the torque can be controlled in both positive and negative directions;

The controller interface displays the main data of the tightening process in real time: actual torque value, angle value, process time, whether it is qualified, etc.; it is displayed and set by the touch screen; ordinary electric screwdrivers can only adjust the torque according to the electric screwdriver, and cannot display real-time torque data.

3. Life: The servo motor usually has a life of 1 million times, which is 3-5 times that of ordinary electric screwdrivers and pneumatic screwdrivers.

4. Cost: The cost of servo motors is usually more than 2 times that of ordinary electric screwdrivers.

The above points have obvious advantages of intelligent electric screwdrivers. In addition to the high cost, the cost issue is also the main reason why the servo tightening system cannot be popularized. In the production design of automatic screw locking machines, electric screwdrivers and pneumatic screwdrivers are usually used as locking power, which has small investment, quick effect, high efficiency and can meet the locking requirements. Servo tightening machines are used for products with high precision requirements (automotive engines, aviation and other fields), and currently servo tightening machines only perform tightening actions (such as screwing car tires) without delivering screws and nuts. Fully automatic servo tightening machines (with functions such as automatic screw feeding and automatic screw tightening, and can operate without human intervention) are still relatively rare.
