Definitions

  • the present disclosure relates to an adaptive and modular fixture and clamping arrangement. Particularly, but not exclusively, the disclosure relates to an adaptive and modular fixing device. Aspects of the invention relate to an adaptive and modular fixing device and to an adaptive and modular system for holding a workpiece.
  • a workpiece should be fixed securely to a work bed or table to allow the machining or other process to be undertaken on it. If a workpiece is not secured properly then any movement of the workpiece could result in misalignment of the machining equipment causing a miscut for example. Misalignment of the workpiece and machining equipment may result in the workpiece to be wasted as scrap.
  • a workpiece holding device is therefore required that overcomes the limitations of known workpiece holders.
  • an adaptive and modular fixing device comprising: a housing; at least one stationary pin and a plurality of moveable pins suitable for mounting a workpiece upon; at least one retention or clamping feature; at least one mounting element suitable for removably fixing the adaptive and modular fixing device to a surface; and a lock; wherein the at least one stationary pin plurality of moveable pins, the at least one retention or clamping feature, the at least one mounting element and the lock are connected to the housing; wherein the lock is adapted to lock the plurality of moveable pins in a fixed position; wherein the plurality of moveable pins are moveable in a longitudinal axis relative to the housing; and wherein the at least one stationary pin, the plurality of moveable pins and the at least one retention or clamping feature are adapted to fix a workpiece to the adaptive and modular fixing device.
  • the adaptive and modular fixing device is able to hold a workpiece preventing the workpiece from moving whilst the workpiece is inspected or assembled or machined or worked upon.
  • the adaptive and modular fixing device is able to retain a workpiece securely via the combination of moveable pins, stationary pins and the at least one retention or clamping feature.
  • the moveable pins are actuatable such that they move around and cradle the workpiece placed on the adaptive and modular fixing device.
  • the ability for the moveable pins to adapt in position and form a complementary surface to the workpiece produces a stronger hold than holding the component in a conventional clamping arrangement.
  • a further advantage of the moveable pins forming a cradle around the workpiece is that any clamping pressure is more uniformly distributed onto the workpiece.
  • Conventional clamps may distribute clamping force onto a single point on a workpiece this may damage the component (deforming metal surfaces or cracking composite structures for example).
  • the present invention reduces this issue by distributing forces more evenly.
  • the lock allows the moveable pins to fixed in a fixed position.
  • the fixed position may be the cradle type surface obtained when the part is placed in the adaptive and modular
  • the lock prevents the moveable pins from moving. Doing so negates the need to re-setup the adaptive and modular fixing device when one workpiece is taken out of the assembly and replaced with another similar/identical workpiece in the same orientation.
  • the lock reduces down time between each machining operation for example when the first workpiece is removed, and a second similar workpiece is fixed to the adaptive and modular fixing device for the same machining operation to occur.
  • the arrangement is a universal fixing arrangement suitable for holding workpieces of many different shapes and in many different orientations.
  • the ability for a universal fixing arrangement of the adaptive and modular fixing device means that said device can be used for many different workpieces and many different orientations of workpieces.
  • the ability to reuse the adaptive and modular fixing device for different workpieces and orientations means that the same adaptive and modular fixing device can be used many times over multiple production runs for different components. A single use workpiece holder by comparison would no longer useable after a production run for a specific workpiece has finished.
  • the present adaptive and modular fixing device is therefore a greener, more environmentally friendly product due to the reduction in scrapped single use workpiece holders.
  • the adaptive and modular fixing device is adapted to hold workpieces of up to 1500 mm in size, up to 1000 mm in size, or up to 500 mm in size.

  • the advantage of this set up means that the adaptive and modular fixing device does not require being fixed permanently to a machine bed or worktable.
  • the moveable pins are biased to an extended position. Biasing the pins to an extended position means that they will return to their unactuated shape when the lock is released and/or when a workpiece is removed.
