In most assemblies that are joined with threaded fasteners, the cost of the fasteners is not as important as the cost of installing them. That makes choosing the right fastening tool of paramount importance. Pneumatic tools are inexpensive, but DC electric tools offer more control and precision. Cordless tools enable assemblers to access fasteners in confined spaces, but they’ll need a steady supply of fully charged batteries.

Do you need torque control, angle control or both? Is it a hard joint or a soft joint? Is it an ordinary rundown or a "safety-critical" joint? Could the materials crack or strip if the fastening parameters are insufficiently controlled? Do the fasteners need to be installed in a particular sequence? Is data collection and analysis important? Is ergonomics a concern? If production volumes are high enough, you might be able to justify an automatic screwfeeding system or even a screwdriving robot.

Here's a look at the latest equipment for installing threaded fasteners. All the products here will be on display at The ASSEMBLY Show South, which will take place April 4-6 at the Music City Center in Nashville, TN. Besides fastening tools, you’ll find some 150 suppliers of automation, robotics, motion control technology, parts feeders, manufacturing software and other assembly technologies.

Pulse Tool Offers Continuous, Discontinuous Modes

The AcraDrive pulse tool offers three tightening strategies that are programmable with the AcraDyne Gen IV controller: continuous mode, discontinuous mode, or continuous and discontinuous mode. This means that one tool can cover more applications. Engineers do not have to make trade-offs between ergonomics and low cost of ownership or between high speed operation and data collection.

In continuous mode, the tool can be programmed to run like traditional DC electric nutrunners with ergonomically acceptable limits. In discontinuous mode, the tool provides virtually reaction-free performance with great accuracy, high speeds, and controllability. In combined mode, the tool has the unique ability to deliver torque in both continuous and discontinuous modes.

The torque is measured by an industry-standard strain gauge transducer, providing high accuracy and minimizing errors in the assembly process. Sealed brushless optimized motors ensure reliable operation with zero maintenance requirements.

The lightweight, low handling force and smooth movement make the tool suitable for fast one-handed tightening. In addition, AcraDyne developed a proprietary motor control algorithm to regulate speed, torque and various performance characteristics for precision positioning and tool balance.

The tool connects to the controller using the same durable cable that connects to all AcraDyne tools. No software add-ons are required, and no-cost updates are available through AIMCO's website.

Experience clear and concise data connectivity when integrating the AcraDrive with an AcraDyne Gen IV iEC Controller. With an intuitive user interface, the iEC Controller connects to all major protocols, buses and line control systems in use today. Data storage and transfer to QMS systems enables robust process management in today's data-driven world.

Digital Torque Wrench

The OPEXplus digital torque wrench can measure both torque and angle of rotation. Accurate and ergonomic, the tool covers a range of torques from 3 to 800 newton-meters, and it transfers tightening results to any IT system without the need for additional control.

OPEXplus torque tools are recognized in in shop-floor networks via an embedded WiFi module. When a tool in an assembly line is changed, the module can simply be plugged into the new screwdriver. The software allows parameterization via a hotspot, the factory network or a serial interface.

The wrench transmits tightening results with a tightening curve, as well as maximum torque and angle of rotation. It supports popular protocols such as OpenProtocol, IPM or XML. A standard 21700 lithium-ion rechargeable battery supplies the power.

The wrench has a scanner to read bar codes and QR codes and transfer them to higher-level systems quickly and correctly.

An LED display ring on the handle is visible from all directions and shows the tightening process and result. An optional vibration module is also available to provide tactile feedback. The color display allows wrench to be operated intuitively. The housing is made of a robust titanium-aluminum alloy with an anti-slip handle cover.
