Can a Lift and Rotate Mechanism Handle Heavy Duty Machining Needs?

Click For Summary
SUMMARY

The discussion centers on designing a CNC machining fixture that incorporates a lift and rotate mechanism capable of handling heavy-duty machining needs, specifically with a lifting capacity of 15 to 20 tons. The user seeks inspiration for a fixture that raises to clear guide pins, rotates 120 degrees, and then lowers back over the guide pins. Suggestions include exploring rotary CNC tables and cylindrical cam mechanisms, as well as examining plug valves that utilize linear and rotary motion.

PREREQUISITES
  • CNC machining principles
  • Understanding of rotary CNC tables
  • Familiarity with cylindrical cam mechanisms
  • Knowledge of heavy-duty machining requirements
NEXT STEPS
  • Research designs for rotary CNC tables with lifting capabilities
  • Explore patents related to cylindrical cam mechanisms
  • Investigate plug valve designs that incorporate linear and rotary motion
  • Examine case studies of heavy-duty CNC machining fixtures
USEFUL FOR

Mechanical engineers, CNC machinists, and product designers involved in creating heavy-duty machining fixtures and seeking innovative lifting and rotating solutions.

Hi all

I need a bit of inspiration for a new CNC machining Fixture design. First the top of the fixture must be raised to get free of the guide pins, and then the top must rotate 120 degrees before it must be lowered over the guide pin again.
I was looking for something like a rotary CNC table, but which is raised before rotation.

Can anybody help me?

Examples of where this principle is used, some drawings, or even some manufactures of a similar product.

Thanks for your help

You need to tell what is the size of the fixture you are designing.You might be interested in Plug valves where the plug has a linear motion followed by rotary motion.I suggest you to search for some patents which use a cylindrical cam mechanism.
 
Hi again

The fixture must have a lifting capacity of 15 - 20 ton.

It's for heavy duty machining.
