Fixture for flexivity testing of MCCB Knobs Polarity Testing Setup Working Principle Component is fixed from one side (as in case of breaker) & allowed to bend from another side so that load is applied vertically at extended part of Knob. Here, the contact occurs between tool & component is line contact. Hence, we have designed the fixture in such a way that, as the load is increasing, the plastic Knob tends to bend downwards proportionally & we can get the accurate values for Load Vs Displacement.
Fixture for flexivity testing of MCCB Knobs Design of fixture:- Guiding System Vice Pin (Moving) Bush Pin Rod (Fixed) Vice Moving Part Knurled at Lower Surface Vice Main Body (Moving) Base (Fixed on Ram)
Fixture for flexivity testing of MCCB Knobs Advantages of the Fixture:-
Flexivity i. e. load Vs Displacement values of the Knob can be accurately found out.
Used for all the types of MCCB i. e. Multi purpose.
