MCC Description

MCC stands for (M)ounting Module, (C)lamp (C)ollar kit.  

The MCC directory in the public area can take you to specific MCC datasheets.

A clamp collar kit is required to connect any two RISTEC modules together or to connect a RISTEC module to an Adept robot.

There are two models available, one being the standard clamp kit and the other having slots for use with customer designed tool racks.

Clamp collar kits are comprised of two identical clamp halves, a pilot ring, a locating pin and a key. The truly unique design of the kit allows it to be used to connect to any old or new Adept robot simply by selecting either the pin or the key and flipping the pilot ring one way or the other. This concept is shown on the ADM page.

When connecting two RISTEC modules together you can use either the pin or the key and insert the pilot ring in either orientation.

The design of the clamp collars allows easy access to the interface of modules for maintenance and repair. The clamps can be unscrewed and removed with an Allen wrench. All competing lines of products require that they be screwed together using expensive, custom adaptor plates. As they add products to the stack, they bury the hardware connecting the units. Maintenance requires the complete dismantling of the end effector for even the simplest repairs.

The collar creates a very rigid connection of the modules because the clamping happens at the periphery of the modules. Putting the material at the furthest most point from the center has a very high moment of inertia and thus makes the connection very stiff with the use of a very small amount of material. It might seem that the screws holding the two collar halves together are small for the types of payloads the modules can handle. However, the screws actually see very little load. The wedge profile of the collars generates a very large coupling force holding the modules together. This is easily demonstrated by connecting any two modules using the pilot ring and dowel pin and then tightening the screws to seat the collars. Remove the screws and try to separate the modules from another. As you’ll see the modules stay clamped together with no separation and no disengagement of the collars.
