While the standard connection for t-slot extrusions is the most cost effective and commonly used joint there are situations where a different solution is required.
A good example of this is the fixing, or clamping, plate joint used to make a perpendicular joint between two pieces of t-slot profile.
The main difference between a fixing plate joint and a standard joint is that the fixing plate is easily relocated along the t-slot side of the joint. This feature alone makes this joint a smart choice for prototyping applications.
A fixing plate is an accessory that attaches to the end of one piece and into the t-slot of the other piece. A fixing plate joint requires only a hex key to assemble or dismantle.
This also suits applications where the equipment, such as exhibit displays, often need to be dismantled for transportation or storage. Another application would be machine framework, or components, that need to be adjusted, from time to time.
We stock fixing plates to suit both the 40 and the 45 series t-slot aluminium extruded profiles. We also stock a comprehensive range of alternative connector type and joint components. For more information use our contact page or telephone 07 3823 1079.
So, in summary, fixing plates are useful where:
- Components need semi regular removal or relocation
- An existing component obstructs or prevents a standard joint
- Additions need to be made to an existing structure
- The framework needs to be adjustable (eg: prototyping)
Constructing a fixing plate joint.
For this example we will use a 40×80 clamping plate (084.308.004) to join a 40×80 profile (084.102.002) piece to a 40×40 profile (084.102.001) piece. The first step is to bolt the clamping plate to the end of the 40×80 profile via M8 tapped core holes.
Having bolted on the clamping plate, bolts with slot nuts are fitted to the clamping plate ready to slide into the 40×40 slot. In this case we are using the standard 13mm square M6 nut (084.302.003) as the slot nut.
When the 40×80 piece is slid into place, a hex key is used to tighten the bolts on the slot nuts. This completes the joint.
Once a clamping plate joint is completed that’s not the end of the story. Relocating the joint is as simple as loosening the slot nut bolts, sliding to the new position and re-tightening.
