Metrology fixtures for vision systems

Renishaw's vision fixtures and acrylic base plates allow for back lighting and a clear, clean look at the part from your vision system and multi-sensor machines.
Renishaw vision fixtures provide repeatability and secure work-holding for any size, shape or type of part for measurement on your vision system. Hold even the smallest of parts in a wide variety of ways while maintaining a clear view of the part.

Hold small and delicate workpieces

Renishaw has a wide selection of modular metrology fixturing components, designed to hold even the smallest of parts, allowing for maximum visibility and probe access without obscuring any critical features.

Cut inspection time

Minimise down time waiting for fixturing to be set up by keeping your parts set up on multiple plates, switching them on and off the machine in seconds. Plates can be loaded and unloaded rapidly using quick release magnets.

Our acrylic plates allow components to be backlit, with our multi-window plates providing an unobstructed view of components. Mirrors can be used to view features on the side of components, reducing the need for reorientation.

Reproducible set-ups

Identical fixturing set-ups are important to ensure the repeatability of inspection by removing variation from the process. Set-ups can be accurately documented and reproduced using our alpha-numerically labelled base plates and labelled fixturing components.

Build a vision fixturing kit

To fixture a component on a vision machine, a Quickload corner, base plate and a fixture kit will be needed. The type of parts you are going to fixture, your machine and application, will determine the kit you choose. Additional components may also be required, depending on the nature of the workpiece being fixtured.

Step 1: Choose a QuickLoad corner

Quickload corners come in multiple form factors, each designed to fit specific models of vision machine. It is designed to fit the lower left hand conrer of your vision stage and the location of its mounting holes. Mounting holes are provided for most major brands of vision systems, to ensure the correct size and proper fit.

The edges of the QuickLoad corner are serrated so that parts can also be mounted directly against them and fixed with Renishaw M4, M6 or 1/4-20 fixturing components, for quick and easy inspection.

Step 2: Choose a base plate

Renishaw acrylic base plates contain recessed steel pins that locate precisely onto magnets within the QuickLoad corner. this enables quick, easy and repeatable loading and unloading of plates on to the machine. There are two base plate options to choose from:

  • Multi-hole: which offers greater flexibility to set up and check as many parts as possible at one time with a clear area in the centre of the plate
  • Multi-window: with more windows for the clearest view of small parts.

Step 3: Choose a component set

Renishaw vision fixtures can be purchased in preconfigured kits. A kit consists of a set of components designed to hold small intricate parts, ferrous or non-ferrous.

Vision component sets are available in an M4 thread size.

Step 4: Choose additional components

Additional vision components can be purchased separately and used alongside the preconfigured component set. Fixturing components are easily adjustable and designed to hold components firmly with the minimum necessary force to avoid damage or distortion. The wide range of parts available offers flexibility when setting up a fixture to ensure a clear probe path for inspection.
