CNC Plasma floating Z torch mount for machine or handheld torch

Last crawled date: 4 years, 2 months ago

Floating Z torch mount for CNC plasma cutter.
This is intended to fit on a linear actuator with M5 holes on a 60x20mm and/or 40x40mm spacing.
I used it to mount a 'CNC Plasma Cutting Torch P80' from eBay - I cut down the tail tube a bit as it got close to the Z motor. See my other designs for the Z motor mount I used.
It's designed for a 35mm diameter machine torch OR a 32.3mm handheld torch.
I designed it to suit an 'Ergo Cut S45' torch, and so the mounting collar is either flush with or 30mm below the backplate to allow the torch to protrude below the Z actuator sufficiently - see images.
Needs:
4x LMF6 linear bush bearings
8x small self-tapper screws to mount bushes
2x 100mm x 6mm linear chrome rods
2x springs (around 9mm x 20mm seemed to work OK)
4x or 8x M5 10mm tapered head screws
1x Micro-switch with roller. I used a V-156-1C25
2x Tapered M3 x 20mm screws + washers & nuts to mount switch
4x M4 screws/washers/nuts to mount torch (2 for hand-held torch mount)
