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:

006 Toggle Clamp Modeling & Assembly - Part #5

This tutorial shows how to model the Handle using the Part Design module. The plate has the following dimensions:

To model the Handle , four steps will be done:

1. Two Bodies will be created, the first one will be drawn and then extruded.
2. Then, we insert a body for which we create a profile projected on the surface of the first body.
3. The profile of the second body is then extruded.
4. Boolean operation "Intersection" is done to create the final part.

Here are the videos that demonstrate the modeling of the Handle:

005 Toggle Clamp Modeling & Assembly - Part #4

This tutorial shows how to model the Handle Support or the main clamping part using the part design module. The clamping part has the following dimensions:

To model the Handle Support or the Clamping Part, four steps will be done:

1. Two Bodies will be created, the first one will be drawn and then extruded.
2. Then, we insert a body for which we create a profile projected on the surface of the first body.
3. The profile of the second body is then extruded.
4. Boolean operation "Intersection" is done to create the final part.

Here are the videos that demonstrate the modeling of the Clamping part:

004 Toggle Clamp Modeling & Assembly - Part #3

This tutorial shows how to model the L-shape plate using the Generative sheet metal module. The plate has the following dimensions:

To model the L-Plate, four steps will be done:

1. The down-side of the L is created and extruded using wall button.
2. The up-side of the L is created and extruded using build wall on edge.
3. The part to be removed is drawn on the upper side and removed using the cut-out button.
4. The holes are created using the "create hole" button.

Here is the video that demonstrates the modeling of the L-Plate:

Here is another video that shows how to simply create the mirror part of the first L-Plate which will be used in the Toggle Clamp Assembly:

003 Toggle Clamp Modeling & Assembly - Part #2

This tutorial shows the modeling of the Connection Plate which is the second part of the toggle clamp. Its drawing and dimensions are shown in the image below:

To model the the Connection Plate, two steps will be done:

1. The main cross section including the holes will be drawn.
2. The whole section will be extruded using the "pad" tool.

Here is the video that demonstrates the modeling of the Connection-Plate:

002 Toggle Clamp Modelling & Assembly - Part #1

In this video tutorial, a Toggle Clamp is modeled and assembled using CATIA. It is mainly composed of sheet metal having a thickness of 2 mm. It has a mechanism moving forward and backwards. Actually, this tutorial is a kind of reverse engineering tutorial because I got this Clamp and modeled it. In this tutorial, several Generative sheet metal techniques and Part Modeling techniques are introduced. So I hope this could be of benefit for those who are interested in sheet metal modeling. Shown below are the pictures of the assembled Toggle Clamp.

In the above image, The open-position of the clamp is shown where the grip part is 100% vertical and the handle (the red one) is brought downwards. In this position, the workpiece is let free. By then, the operator can replace the workpiece by another one.

In the above image, The close-position of the clamp is shown where the grip part is 100% horizontal and the handle (the red one) is brought upwards. In this position, the workpiece is fully clamped. By then, the operator can apply whatever production applications he needs to add.

This modeling is long and is, thus, divided into several parts. Today, we will start with part #1 which is the Pin. The rest of the parts shall be found at these links:

• Second Tutorial
• Third Tutorial
• Fourth Tutorial
• Fifth Tutorial
• Sixth Tutorial

To model the the pin, two steps will be done:

1. The main cross section will be drawn and revolved around the axis.
2. A chamfer will be applied to the top of the Pin.

Here is the video that demonstrates the modeling of the Pin:

001 Let's learn Catia

This blog is intended to be a learning community for Catia for both amateurs and professionals. This blog is a tutorial oriented blog where learning will be through both videos and explanatory snap shots. Your participations are highly appreciated through asking questions and providing feedback about the tutorials in the comment box.

Some of the tutorials in this blog are based on tutorials explained in books and on the web but handled in a more detailed manner while some others are created uniquely by us. The level of difficulty of these tutorials varies from a beginner level up to a professional level.

I hope that all readers and followers of this blog get the most benefit possible.
