Productivity with Electrical Assembly tools
Introduction
Regardless of the size of the business, continuous improvement of productivity is vital to augment gross profits and to remain competitive in the market. Productivity on the Assembly shop floor mainly depends on the combination of efficient employees, equipment, and processes. Therefore, in developing industry, an employee can only be as productive as their tools.
The use of electrical assembly tools for fastening and assembly delivers faster, accurate, and easy output while reducing the cost of labour, risks of injury, thus increasing productivity.
1. Manually operated vs Power Operated Assembly Tools
Assembly tools are used in assembling machinery and equipment components may be either manual or power-driven. Manual tools include standard or special tools for assembling threaded connections, including wrenches and screwdrivers, standard and soft hammers for pressing the parts, dies, and punches for riveting work, Pliers, and various tools for installing piston rings and washers.
Power-driven tools include hand-held electric machines for fastening threaded connections, such as screwdrivers and nut and bolt drivers, electric hammers, portable clamps for pressing and riveting, power-driven rollers for installing elastic parts, such as piston rings, split locking rings, and springs.
The use of power-driven assembly tools increases the efficiency of assemblers by a factor of 20% to 25% as compared with the efficiency obtained with manual tools. Electrical assembly tools are widely used in large and mass production operations. An important requirement for the use of power-driven tools is the training in specialized lines of work and the standardization of fastening components.
2. Electrically Operated Assembly Tools
As discussed in previous sections, electric screwdrivers are the smart choice for high-volume manufacturers who want to increase productivity. The main Electrical assembly tools are Electrical Screwdrivers and Electrical Nutrunners-.
Electric Screwdrivers –
An electric screwdriver is a portable device that allows different types of screw heads to screw and unscrew effortlessly. The screwdriver head is equipped with a bit holder for a quick release system often a magnetic type, allows for quick insertion of the screw bit corresponds to the screw heads. These screwdrivers can be seen at assembly lines and stations for safety and quality critical applications.
- Electrical screwdriver - The standard models use brush motors and over a period of time wear and tear occur on expandable parts like carbon brushes, commutators, switches, and other contact points. The heat generated by the motor may shorten the operating life of the screwdriver. Wear on the expendable parts can affect its performance, causing the screwdriver sometimes to stop operating. Hence, these standard screwdrivers require periodic maintenance and parts replacement depending on the amount of usage time and the environment it is used in.
- Brushless Electric Screwdriver - Screwdrivers with brushless motors have an enormously long usage life with no need for periodic maintenance and replacement of expendable parts. As the heat generated by the motor is relatively less in this type, performance is always at its maximum level and resulting in reliable product quality. The brushless screwdriver ensures product safety, reduction in maintenance cost, and an overall reduction in failures.
Electric Nut runners –
Nutrunners and Nut drivers are tools used for tightening nuts. By the name itself, nut drivers are purely mechanical hand tools, while Nutrunners are pneumatic, electric, or hydraulic power tools. Electric Nut runners utilize angle-controlled tightening with very high precision with an integrated gyroscope using the True Angle function. These compact Nut runners are packed with many other innovative features that make the job easier and safer for the operator. Electric nut runners use a DC controller as a power supply. Types of Electrical Nut runners are -
- Straight Nutrunners
- Angle Nutrunners
- Pistol Grip Nutrunners
3. Selecting Nut Runners
Selecting nut runners requires a bit of study on available features. For example, integral transducers are often used to provide feedback to the monitor and control system. Torque levels and the number of tightening cycles are displayed on the digital display panel. Handheld nut runners often include a reaction bar or stabilizer to facilitate ease of use.
4. Monitoring & Control
Software-based control systems provide in-built monitoring and control systems for tightening operations performed using the electric assembly tools. Thus, process control and quality assurance are made simple by these advanced control systems. These systems guide the operator through the in-built functionalities to avoid mistakes, otherwise, these can result in costly quality issues.
5. Applications of Electrical Assembly Tools
Its application can be found in every industry and not limited particular type. Even one can use these portable and noiseless assembly tools for domestic purposes too.
