SOLIDWORKS Design & Help

Hello,

I'm interested in your project. Let me know if you want my service.

Regards,

Joe

Hi i would sure be habby if you could help me figure out a way.

I will need more information about the project

I will need more information about the project

I will be happy to provide you a detail design with the information you provide. I can send you the files once you provide more information about the load and travel requirements.

I have made some assumptions and created a line diagram.

Lock out a link at 45 degrees inclination. When the hydraulic cylinder starts out at 60 mm, the variable dimension =>60 mm will start decreasing equally to the stroke of the hydraulic cylinder. The 45-degree link will have a slot to let the Y (shown as 60.00 mm vertical) to move only in the vertical direction.

Hope this helps!

Travel will be 500mm of the Hydraulic cylinder, the load is about 50kg-350kg on Y-Axis.

what kind of information do you still need?

If you just need the concept, I probably don't need any, but if you need the whole design in details, I am going to need dimensions.

Regards

I can give dimensions but I only need a well thought concept

There are a few ways of doing it. You can decide which one you prefer.

For that load case, there's won't be direct translation. On assumption that your current Y-motion is hydraulic driven , I have a conceptual not detailed) design solution that may work for your case. No gear. Visit my profile.

what model do you mean I can’t find a useful solution on your profile

Looks interesting but to achieve a travel of 500mm it will need a huge crank

It was a lead to my profile if you'll like to get started. As I said, you cannot achieve direct translation with that load differential. The solution shown by others, so far, are close but won't be practical. What you need is an engineered solution. Can you provide information on how the vertical load is placed or driven?

The force is pushing down on y-axis

I guess a scissor lift mechanism with a CAM atop would work.

Install the hydraulic cylinder horizontally at the bottom left corner. The scissor mechanism tend to product the quadratic variation on the vertical measurement. Install a CAM with the vertical dimensions compensating for the quadratic arc variation of the vertical measurement. The cam would slide left to right as the scissor lift moves vertically.

A spring-loaded plunger is pushed up on a linear guide by the cam. This can make up the 1:1 movement.

I am guessing it is doable and there would be a relatively lesser pressure loss.

I have sent you an explanation on two illustrated approaches. Here is the promised solution file.

You only need triangular frame, it doesn't need to be full circle

but for that distance the simplest would be a form of drive chain inside of a guiding rail , look up "Leaf chain"

Wow looks very promising but how did you plan on connecting the two chains it’s not clear for me.

just use a bell crank
