Assembly technology

Prefabricated parts will be built together to more complexe and bigger assemblies in the course of the assembly process. Therefore components need to be moved, put together and connected amongst themselves in the correct position. According to this requirement there are components that allow moving and handling the parts to put them on the correct position and to connect them.

The submenus show devices and techinical aids for this.

Screw and bolt technology

Modern industrial screw and bolt technology is much more than „just screwing“. In the course of screwing with electrically driven power screwdrivers information about the screwed or bolted joint is collected and stored. The stud torques are recorded, as a measure how strong the respective screw or bolt has been tightened. Additionally, the number of revolutions of each screw or bolt is counted and documented in order to be informed, if the screw or bolt has been screwed in as deep as planned. If, for instance, the number of revolutions is smaller than expected, it could be possible that the screw fits askew, or that the threaded hole is blocked, or the screw or bolt is too short…

The following pages are about industrial screw or bolt technology. There you can see and learn basics about screwing and bolting processes. Please find further details of industrial screw or bolt technology in the submenus.

Nut runner Rexroth ESV146

Schrauber Rexroth ESV146klein

This electrically driven hand nut runner by  Bosch-Rexroth is the biggest nut runner of the ErgoSpin VarioLine with the short name ESV146, which you can find on the model plate.

This encompasses the information that the nut runner’s maximal torque is 146 Nm. One of the manufacturer manuals contains the information that the minimum torque is 29 Nm. So, the the so-called operation spectrum extends from 29 Nm to 146 Nm.

Technically assisted hand assembly sites

Also in modern industrial production, manual hand assembly sites are useful for certain assembly tasks, where people manually put together the parts. For example, hand assembly sites are useful when mounting soft components or when the number of parts to be assembled is not very large. Technological tools are often used to facilitate the work of the assemblers and to ensure that the parts are assembled efficiently and correctly.

The work is facilitated for example by the humane positioning of storage containers, which as intelligent containers when necessary also can automatically order new components.

In order to install the parts correctly, control systems are installed at many assembly sites, which display the correct containers via light signals, from which the next part to be mounted has to be removed.
