Abstract
A plasma cutting system comprising a frame, a work support on said frame and a tubular torch support. Gantry apparatus for moving the tubular torch support laterally and longitudinally relative to work on the work support. The torch support is moved a fixed distance from the work and has a ski cup on the lower end of the tubular work support to move over the work. The tube is urged downward by a spring so that as the ski cup runs over the work, the tube is lifted and held at a constant distance from the work. A torch support bearing in the lower end of the torch tube freely receives the torch in the tube.
Claims11
A support for a plasma cutting torch comprising an upper bracket bearing and a torch tube,
- said torch tube having a bearing fixed in its lower end,
- a torch slidably receivable in said torch tube resting on said bearing,
- said upper bracket bearing adapted to be attached to a plasma cutting system and to support said torch tube,
- said torch having a tip,
- a ski cup on the lower end of said torch tube adapted to be moved over work supported on said plasma cutting system whereby said tip of said torch is maintained in a predetermined relation to work supported on said system.
In combination, a plasma cutting system and a plasma cutting torch support,
- said system having a rolling table for supporting sheets of material to be cut,
- means to support said torch support for movement longitudinally and laterally of said system,
- said torch support comprising a first bracket bearing and a torch tube,
- said torch tube having a bearing fixed in its lower end,
- a torch telescopically received in said torch tube resting on said bearing,
- said first bracket bearing means attached to said plasma cutting system,
- a shoulder supported on said first bracket bearing supporting said torch tube,
- said torch having a top,
- a ski cup on the lower end of said torch tube adapted to be moved over work supported on said plasma cutting system whereby said tip of said torch is maintained in spaced relation to work supported on said system.
