Angle Bracket We will design this small bracket to practice the various ways of using both the Sketcher and Part Design workbenches for designing parts. One of the tools we will use in many different cases is the Sketching of a Profile and extruding Pads. Rua Cotoxó, 411. Sala 44. CEP 05121-000. São Paulo. SP, Tel: XX-11-3675-2799.

to sketch then constrain

the new contour to the boundaries of the existing Pad and apply the appropriate dimensions .

5. Extrude this second Pad to a height of 4 mm.

Defining the Pilot Holes and the Angular Pads for the Bracket Next we would like to create the two angle flanges (clevis).

To create this geometry, we will require an angular Plane at 24 Degrees with respect to the YZ plane in order to sketch our profile. Since our drawing calls out the position of these flanges from the position of the pilot hole located between the flanges, we will make our plane pass through the center of this hole so that we will readily have available the values of the extrusion limits. Since our 24 Degrees Plane will pass through the center of one of the pilot holes, we will need to locate this hole in the model. Consequently, we might as well create all the pilot holes first. and finally 1. Position the first hole by first selecting the reference edges, the Hole feature icon, the top of the pad into which the holes are drilled. Put in the appropriate locating dimensions and the hole diameter per the part drawing at the beginning of this exercise. Use the Up to Next option.

and 2. Position the second hole by first selecting the reference edges, the Hole feature icon, finally the top of the pad into which the holes are drilled. Put in the appropriate locating dimensions

, and finally the 3. Create the third hole by first selecting the rounded edge the Hole feature icon top of the pad into which the holes are drilled. Put the appropriate hole diameter (3), the hole is automatically centered on the rounded edge. Use the Up to Next option.

We will now create the 24 Degrees plane through the center of one of the pilot holes. To do it, display the Plane icon by selecting the View + Toolbars + Reference Elements (Extended)

4. Select the Plane icon and create the required plane using the Plane Type of “Angle/Normal to Plane”. Select the vertical pad wall as reference and the pilot hole as the rotation axis for the plane. Put in –24 Degrees to get the desired orientation.

5. To redefine the PartBody as the In Work Object place the cursor on the PartBody in the tree then select the Define In Work Object command from the contextual menu.

and apply the appropriate dimensions.

7. Create a pad from this sketch with a thickness of 4 mm. (use the 2 limits option).

We will now create the other Clevis by using the Rectangular Pattern tool (you can find this tool under Insert/Transformation Features) , select the existing Clevis, select the red edge below 8. Click on the Rectangular Pattern Icon for the reference direction, and put in 2 instances spaced at 16 mm.

Building the Hinge In this exercise, you will build the hinge part using the following tools: sketcher, constraints, pad, pocket, hole, draft, fillet, mirror and pattern. First we describe and discuss the methodology used to build the hinge; you don’t have to read it - you can go ahead and build the hinge your way with the information given on this page.

We will duplicate it with a user pattern – and not a simple copy & paste - to ensure that later if a modification is needed on the bearings, we will be able to do it only on one of them – the others will follow automatically. Enter again the sketcher on the bottom surface of the main pad 14. Draw 2 points
