Hepcomotion has developed a range of actuators for linear motions systems so that each axis operates optimally and contributes to the overall efficiency and longevity of the system. The Hepcomotion light- and medium-duty X-Y-Z systems are suitable for industrial and scientific applications such as pick and place, automated assembly, inspection and product labelling.The X-axis foundation of the system is the PDU2 linear actuator, which features Hepcomotion's Herculane wheel technology in a compact belt-driven unit. The Y-axis requires a particularly high load capacity and stiffness against twisting loads. The PDU2M shares the same technology and format as the PDU2 but with moment load capacity improved by 200 per cent and stiffness by 1,000 per cent. The needs of the Z-axis are different again, with enhanced linear force and higher gearing required.
The PSD80 linear actuator is suitable for this duty, with drive from a super-smooth stainless-steel lead screw operating with a bearing polymer nut. It also uses Herculane wheel technology in a unit that is suitably matched to the other axes in terms of performance, size and cost. All units fit together using standard components to create multi-axis systems that are claimed to perform better than similar units where 'general-purpose' actuators are used for all axes. Lightweight aluminium T-slotted profiles allow the axes to be incorporated into frames, such as the Hepcomotion MCS aluminium frame and Machine Construction System, or more complex machines.
Hepcomotion supplies its X-Y-Z systems as individual parts, in kit form, or fully assembled multi-axis units. This type of X-Y-Z configuration will perform for systems with a working envelope of just a few centimetres right up to those with dimensions of several metres. Motors, drives, cables, electrical connectors and a turnkey service can be provided on application.
