009 Spring Modeling

In this tutorial, a spring is modeled using two modules in Catia: Generative Shape Design and Part Design.

The spring is modeled using four steps in the following video:

1. The helix is modeled in the GS module.
2. Sketch plane is defined at the starting point of the helix in the Part Design Module.
3. A circle is sketched at the starting point of the helix.
4. The "Rib" tool is used where the curve is the helix and the profile is the circle to finalize the spring.

008 Canonic Hopper Modeling

In this tutorial a hopper is modelled using Generative sheet metal design in Catia. It is modelled using the hopper tool.

This hopper is modelled using four simple steps:

1. The parameters of the sheet metal module are defined.
2. The first profile is sketched on a plane.
3. The second profile is sketched on a parallel plane.
4. The "Canonic hopper" tool is used to make the final hopper

Here is the video that shows how to make the hopper in full details:

007 Toggle Clamp Modeling & Assembly - Part #6

In this tutorial, the toggle clamp will be assembled using all the parts that have been created throughout the previous sessions starting by tutorial No. #1 in which the procedure and the concept are described. You shall find all these tutorials in the blog Archive at the left bar of this page.

In The above images shown are the real images of the toggle clamp and the image of the reverse-modeled clamp. Here is the video that shows the simulation of the toggle clamp mechanism:

The assembly was done using the following steps:

1. The handle support and the handle support mirror part are inserted and assembled using two coincidence constraints and one contact constraint.
2. The handle and the handle mirror parts are inserted and assembled using two coincidence constraints and one contact constraint.
3. The L-Plate and the L-Plate mirror part are inserted and assembled using two coincidence constraints with the handle support and the handle itself and one contact with the handle support.
4. The L-Plate mirror is assembled also using two coincidence constraints with the handle support mirror and the handle mirror part and one contact with the handle support mirror part.
5. The connection plate is inserted and assembled using two coincidence constraints with the handle support and the handle itself and one contact with the handle support.
6. Another connection plate (SAME PART) is inserted and assembled using two coincidence constraints with the handle support mirror and the handle mirror part and one contact with the handle support mirror part.
7. The four pins (SAME PART) are inserted and assembled one by one. They have two constraints for each, Coincidence constraint with the connection plate or the handle and contact constriant with the connection plate or with the L-Plate part.

Here is the video that shows the detailed assembly of the Toggle Clamp:
