Multi-position rotary actuator
Initial situation
When carrying out further processing on tanks, it is essential to move the workpiece reliably into different machining and assembly positions. In particular, when fitting components to the tank lid, flexible alignment of the workpiece is required to ensure optimum access to the assembly areas. Due to the size and weight of the tanks, the workpiece must be held securely in the positions it is moved into. Even when forces are exerted during machining, the tank must not move from its defined position.
Objective
The aim was to develop a bespoke multi-position rotary actuator capable of rotating the tank or the assembly aid precisely to three defined positions at 0°, 45° and 90°. In addition to reliable and repeatable positioning, it was particularly important to ensure that the large and heavy tank was securely held in place in every working position. This was intended to make assembly and further processing more ergonomic, safer and more efficient.
Our solution
For this application, we developed a bespoke multi-position rotary actuator as part of an assembly aid. The actuator enables the tank to be rotated and positioned precisely into the defined working positions of 0°, 45° and 90°. Once the respective position has been reached, it is held securely in place, ensuring a stable and controlled working position even whilst components are being machined and fitted to the tank lid.
The robust and application-specific design takes into account the size and weight of the tanks, as well as the loads encountered during assembly. This enables the individual working positions to be reliably moved into and securely held. This improves accessibility, supports ergonomic workflows and, at the same time, increases process reliability during tank assembly.
