How It Works

Nucleo Fixture creates an interlocked grid of X and Y  fixture blades connected to a mating base plate from an imported solid CAD model. The top profile of each X or Y blade matches the underside of the component at the blade’s insertion position, creating a “cradle” into which the component is located. Nucleo Fixture includes a range of standard CAD translators and optional translators for most popular CAD systems. These include IGES, Solidworks, SolidEdge, IronCAD, Inventor DWG and DXF, CATIA, Pro Engineer, STEP and Unigraphics.

Nucleo Fixture allows the importation of standard clamp solids files (available from most major clamp manufacturers via the Internet and with a Carr-Lane library already built in). When included in the model for fixturing, these can be inserted into the fixture assembly.

Nucleo Fixture enables component offsetting of the profile on each blade to be offset by a user-definable amount. “Gripper Points” can be included also; these are small semi-circles at set intervals along the blade profile. As needed, these can be filed or ground down if the actual component does not adequately match the computer model.

For large fixtures, Nucleo Fixture includes an option to create internal cut-out features inside each blade to reduce the weight of the overall fixture assembly. This also aids in keeping the fixture cool during the day-run and with welder torch access.

Unlike traditional fixtures, when using the base tab clip mechanism included in Nucleo Fixture - it enables the fixture assembly to be dismantled when not needed and laid flat - significantly reducing storage requirements and therefore precious square footage.

These fixtures are still used in production in a robotic welding cell, where over 40,000 repetitions have been executed. However, should they wear out, replacement ones are cheap.

Nucleo can provide cut-through or etched marking for assembly assistance along with base plate text for part-number and company logo etc. Duplicate fixture parts can also be identified and the quantity changed from one to the necessary amount in the exported report created at DXF output.

Return On Investment

Compared to traditional fixture costs, Nucelo Fixture results in enough overall savings to pay for itself within a small number of fixture runs. Example ROI:

Total savings first quarter after purchase: $6740.44

"We have made about 8 new fixtures last quarter. We estimated each fixture saved on average $500 in material, labor, and programming time. Most of these were simple fixtures for welding applications, but we have had some success in making very large fixtures.

This one is about 66 x 125” and we estimated it saved over $3000 in material and labor compared to making a formed sheet metal fixture. I even made a trunnion so we could rotate the part for better weld angles and reaching the welds.

There is something that we are not measuring directly, but know - of which is lead-time. We can have a jig cut out overnight with the lasers, put it together in the morning, and have it in production later that day. That process saves at least 2 days compared to our old method for simple jigs. Also, on 2 jobs so far we have decided to cut a copy of the same fixture and have 2 workers welding at the same time. This has been a huge benefit.
