Distance of the outer edge of the locking piece from the outer edge of the U-beam: 12.5.
Add the conveyor roller
Right-click function: Add > Model or add model with -browser (VX_AS5-A1)
Rotate it around the blue Z axis 90° with auxiliary function: Rotate around the Z axis.
Click the location of the series from space.
Place the conveyor roller
Add a concentricity constraint between the roller shaft and the locking piece.
Add a distance constraint between the end of the roller sleeve and the inner edge of the (upper) locking piece: 2.
Create a pattern from a conveyor roller
Select a roll from the assembly feature tree.
Right-click function: Pattern.
Lenght-direction, Number value: 11 and Formula: R_PCS, Delta value: 400 and Formula: R_GAP.
Width-direction, Number value: 1
OK.
Click to the position of the pattern auxiliary geometry line at the end point of the axis.
Choice of assembly from geometry
If you selected a roll by clicking to the roll geometry, only a part (eg roll shell) should be selected by default.
A mini-toolbar opens next to the cursor, allowing you to expand, collapse, or return to the original part selection.
The Plusbutton selects the next higher level assembly, etc.
The Minusbutton clears the selections one assembly level at a time.
The Part button returns to the selection of the original part.
If the number of rollers or locking pieces does not change, check that the patterns dealing with them have the above-mentioned variables in the Formula fields.
Try machining the screw holes in the U-beams
In the support piece (VX_AS5-P1) has a machining feature (red cylinder), whose length you can control using a dimension table.
If some part of the assembly includes a machining feature, or the entire part has the Tool properties, then you can find the right-click function: Machining features > Execute.
Try the above function.
Hide the locking pieces at once.
Click a pattern of locking pieces from the feature tree.
Hide selected parts with or right-click function: Hiding > Hide.
If no holes were created in the U-beam, then the properties of the U-beams should be changed.
Visibility of the Machining feature
In the part model, the machining feature is always displayed.
In the assembly model, the visibility of the machining feature is controlled by the
key.
Saving the machined part
You can save the part machined in the assembly as a new part:
Click the part (which has been machined).
Right-click function: Machining features > Save Machined as New.
Enter the Label for the part.
If you want to change or add the archive information of part, first open the part in a browser and then change the information. (that is, it is not possible to edit them during saving.)
No machining is done for the original link model.
Note that machining is not done on the original link model, but only on the geometry that appears in the assembly.
This is because the same (link) part may be involved in many assemblies, and it is not appropriate to apply machining to all assemblies.
If you should also work on the original link part, use the right-click function: Boolean and use the operation:Subtract with the tool.
Allow U-beam machining (if required)
In the main assembly, select the frame assembly VX_AS5-A2.
Right-click function: Edit.
Click the U-bar. (both in turn).
Right-click function: Properties.
Under Machining with feature in assembly: Select Allowed and Allowed also as link.
OK.
Return to the assembly:OK.
Right-click function: Machining features > Save Machined as New.
Execute the Machining again after editing the model
If you adjust the number of conveyor rollers using the dimension table or the conveyor frame is updated to the assembly, execute the machining features again.
Save the model and save it also to new model
File > Save or click or press
File > Save as New
Enter the label.
Enter the archive information by clickingArc.Data.
Accept the same project.
OK.
Replace the locking pieces with a bearing bracket
Select the first locking pieces of the pattern (VX_AS5-A3).
Right-click function: Change.
Select bearing bracket VX_AS5_UCP205B as a replacement part.
There is a valid selection in the Change Part dialog: Change this because the part being replaced is in series.
You will see that the bearing comes in the wrong position and the constraints associated with the locking pieces go red and no pair can be found for them.
The constraints will turn red if they are not come true.
The constraints are followed by the symbol ->, which means that there is no other party to the constraint (surface, line or point).
An other way to change parts (when the issue is difficult)
An alternative way to handle the replacement of the locking pieces into bearing brackets and the bearing roller into a fixed roller could be to remove both the existing rollers and locking pieces and first add the bearing bracket as a pattern and then a new conveyor roller as a pattern.
Turn the bearing to the correct position
Open the model VX_AS5_UCP204.
Right-click function: Edit Model > Move the whole geometry of part.
The Dialog Move Geometry opens.
In field BlueZ rotation enter: 90.
OK.
Save the model and remove it from the desktop.
The history stepMoveis created in the feature tree of part, which can be modified to change the position of the part again.
Return to assembly
Update the model with the key.
The program marks the changed parts on a red background in a feature tree.
Update changed parts with right-click function: Update All.
The bearings turn to the correct position, but most constraints are in red.
Edit the constraint, that is, reconnect it to the new face
Click the red coincident constraint (which affects the surface of the U-bar) from the list of constraints.
Right-click function: Edit.
Click the red element (Face).
Right-click function: Change.
Click to the part you were going to click to the face, in the figure 1).
Click on a face of the part, in the figure 2).
In the same style, you can edit other bad constraints.
At least modify the Concentricconstraint by placing the concentricity on the bearing bracket.
Replace the previous Distanceconstraint12.5 from the outer surface of the U-beam to the outer surface of the bearing bracket8.
Another option is to delete the constraints and re-add them.
Replace the bearing roller with a fixed roller
Select the first the conveyor roller assembly on the pattern (VX_AS5-A1).
Right-click function: Change.
Select the conveyor roller VX_AS5-A4 as the replacement part.
OK.
In this case, theConcentric constraint does not turn red. It is solely due to the fact that both conveyor rollers use the same shaft (VX_AS5-P3), so the counterparts (faces) are known.
Remove the previous distance constraint, 2, associated with the sleeve (both faces of constraint have been removed) and add distance constraint to the new conveyor roller sleeve and bearing.
Edit the pattern of bearing brackets
In the feature tree, click the pattern that has the bearing brackets.
Right-click function: Edit.
Enter a new value for the Delta of Width-direction: 661
Smart eyes detect the problem
The bearing bracket is not symmetrical, so now the bearing bracket on the other side is in the wrong direction.
For this reason, replacing the locking pieces with bearing bearings was not the best solution.
A better solution would have been to bring the bearing bracket twice and turn the other into a mirror image and then make a series of both.
As of the main version 27.0.00 (Vertex 2021), parts in the series can be mirrored.
In this case, the bearing bracket could first be made in pattern on top of the first U-beam and then mirrored on the other side with respect to the Vertical (XZ) plane of the assembly.
