oleodinamica pump

[Aranciameccanica]

Hello
I am a student of mechanical ing.
for the technical drawing exam I have to model with catia an overall.
I chose an oleodynamic pump, of which I attached two images (image 024 and 021).
I would need help from you who have so much to teach. . .

I am modeling the base of the pump...the first problem arises with the realization of the four threaded holes.
My idea was to create an auxiliary reference system at the center of the circumference on which the four holes lie, create a threaded hole and then make a circular matrix..How do I create the auxiliary system? Do you have an alternative idea to create the four holes?

Hi.
I remind you that the four holes of the melt fall on a circumference by coincidence. the reference system I would put it in correspondence of the conductive shaft and lying on the level of support with the body.
Obviously this is from the educational point of view.

in reality those who command are the thorns

I believe it refers to the 4 threaded holes around the "mouths" of suction and sent.

in case,
I do not know catia, but I cannot understand the difficulty (unless it is the first time a cad 3d opens).

Sorry, I thought he was referring to the backbone.

However the base is called "body". I assume that an alternative reference system can serve him in the future for the assembly of all components.

Hi.

Marco, I'm at first with a program like a cat, so the realization of the four threaded holes is also a "problem".
excuse also for non-exact terminology and thanks to corrections.

Ultimately, how do I make the four threaded holes? suggest more procedures, please

 

[PierArg]

I would do the circular series

 

[PierArg]

However, for solid modeling you must always reason:

- How would I do that in reality?

in this case the cnc machine would go to drill with a tip following just a circumference

 

[User1]

According to the published image, you should project the first circumference on the plane (with the project geometry function), so you could create a circle with center and create only a circular matrix with four holes and then delete the two that will not fall on the right coordinates, then you create a specular copy and the game is done!

the cnc machine must first drill the two circular sections, and after with a lamare mill it must create the central section!:finger:

 

[User1]

I would do the circular series

but you can't take full advantage of this command! if there are two circular sections you will have to run the command twice!

 

[Aranciameccanica]

so I have to make one of the four threaded holes and then make the circular series. . .
How do I define the center of the hole during the hole command?

.... create a threaded hole and then make a circular matrix. . ♪

I would do the circular series

to this had already arrived and planned the same orange. .

but his problem seems to me to be up: how do you make a hole (flected in the case)?
and then the "vien da se" series. .

According to the published image, you should project the first circumference on the plane (with the project geometry function), so you could create a circle with center and create only a circular matrix with four holes and then delete the two that will not fall on the right coordinates, then you create a specular copy and the game is done!

but really catia is so "complicated" (I repeat that I do not know it)? there is no specific command to create holes by squirting points on a plane (in swx also in 3d sketch on round faces) a little like all cad?
I sketch the flanging face, put a point in axis with the central "forone" (x or y is equal in this case), the quoti at the distance from the center and is done. do the circular set of the hole just made by repeating it 4 times "equipted" on the circumference with center in the "foron".
mirrors everything on the other side and finished. .

He doesn't know how to make a hole in the cat.
reality has nothing to do with it.

How do I define the center of the hole during the hole command?

but do you use quotas and constraints in the sketch?

Still?
we are talking about the 4 threaded holes on the suction and sending faces. the pump body apparently already did.

but then Orangemechanical, the drill holes for assembly bolts like you did?
the system is the same.

greetings
Marco:smile:

 

[Aranciameccanica]

the holes for assembly bolts I made them with the hole command, first select some references (holding the ctrl key pressed) and then the plan on which to execute them. then I defined the center of the hole, with the positioning command of the sketch, which is in the dialog box "hole definition".

I also do the threaded hole the same way and then do the series?

Marco, I can sketch out the points on the floor and then take them as the center of the hole, but I was wondering if there were "cleaner" procedures.

Marco:smile:

but actually catia v5 works with the same philosophy as all cad 3d!:finger: you can create a circular or rectangular matrix, but it only works in the context of features! create a hole sketch, create a pocket, and then you can create a circular matrix of that feature!:wink:

What does "cleaner" mean?
the command hole should give you all the correct elements to perform it.
This is one of the ways I do it with swx:or you can also not put that vertical axis, just give a relationship/wine of vertical with the center of the central hole.
or draw the circumference of the hole center and quoti the diameter of that (the point will be coincident with that circumference).
made that hole you can repeat it (in the part, but also first in the sketch without then making the circular series) with the circular series with axis in the center of the "foron". I don't see her so hard.

Okay done: ...thank you all
forward with the next component! :smile:

Bye to all,
I'm drawing one of the two trees in the pump (technical name? )

I almost completed the design, it is missing only to realize the threaded tang at one of the ends

How can I do that?

I had thought of creating a propeller (in the wireframe and surface design section) and using it as director for extrusion of the thread profile(in the part design section). Can it work? Is there a simpler way?

how do I combine the various pieces that make up this tree? were all created in the same catpart
