Scissor Jack Assembly Design 3

Hello Everyone

 

I am working on a design at the moment using Inventor 2012.

It is a Scissor Jack. It has been designed to specific dimensions.

Although I am making up the majority of them as I go along.

Dim's spec's of which I must design to are as follows,



Max Height @ Open position = 250mm. (must be kept)

Min Height @ Closed position = 70mm. (must be kept)

Max width = 75mm. (must be kept)



The rest I have been taking from other designs of which I saw during my investigation.

I am having some difficulties though. As my Inventor time is still fairly new.

I have been modelling in such a way trying to adapt the open & closed position limitations with the use of constraints as my maximum & minimum limits. In doing so I have set a Drive Constraint so I can show the jack in its mechanical motion. I don't mind making any changes that will help me achieve completing it to act as it should. I believe there is still some tweaking to be done to it, but I feel the actual engineering design to be almost sound. There is an issue with the base via support arms. I cannot have the support arms moving past the floor level.

I will need to place location pins through the saddle & base connecting the arms. Finally If possible alter the gear teeth so that they interlink & coincide with each other. My screw rod also needs to work properly & turn also the nut needs to be localised in the correct position fixed on the screw rod at the end of the Side sleeve.

I have attached the assembly that  I'm now working on.



If you can offer any advice or changes to my model/assembly I would be very grateful.
 
Kind regards
 
Laurence Masson.
 

I'll try to post the drawings for this design over the next couple of days.

Here you go, let's start with this one.  (If I missed any dimensions - you can use the Measure tool.)
Let me know when you are ready for the next part.
