In recent years, China's industry has been continuously developing, and intelligent electric vehicles have played a significant role in it. Ordinary electric and pneumatic screwdrivers are widely promoted by most manufacturers due to their light weight and low cost, while the screw locking work of general industrial products uses electric or pneumatic screwdrivers, which can already meet production requirements and therefore have a high level of awareness.
Intelligent electric batch requires the execution of tasks through servo motors, PLCs, and drivers, and can run complex algorithms. Its torque control is more accurate, can provide real-time torque values, and execute actions according to torque reference values, completing high standard and difficult locking work.
Briefly introduce the difference between smart electric batch and regular electric batch:
1. Speed: The servo motor has high output, fast response, high speed, small inertia, smooth rotation, and stable torque.
2. Accuracy: The servo motor can achieve high-speed real-time detection and high-precision control of tightening torque values; Torque can be controlled in both directions;
The software interface displays the main data of the tightening process in real-time, including the actual torque value, angle value, process time, and whether it is qualified; Displayed and set by touch screen; Ordinary electric screwdrivers can only adjust torque based on the electric screwdrivers and cannot display real-time torque data.
3. Service life: Servo motors typically have a service life of 1 million times, which is 3-5 times that of ordinary electric and pneumatic screwdrivers.
4. Cost: The cost of servo motors is usually more than twice that of ordinary electric motors.
The above advantages of intelligent electric screwdrivers are obvious. In addition to high cost, cost issues are also the main reason why servo tightening systems cannot be popularized. In the production design of screw machines, electric and pneumatic screwdrivers are usually used as locking forces, which have low investment, fast effectiveness, high efficiency, and can meet locking requirements. Servo tightening machines are used for high-precision products (in the field of automotive engines), and currently, servo tightening machines only perform tightening actions (such as tightening screws on automotive tires), without conveying screws and nuts. The application of fully automatic servo tightening machines (with functions such as automatic screw feeding and automatic screw tightening, capable of unmanned operation) is relatively limited.
