Abstract
A torch height control apparatus with a synchronous belt drive, altering wheelbase of the wheel axis and solid body, attached to the gear belt on various mechanized shape cutting machines is provided for positioning the tip of a torch with respect to a workpiece to a predetermined height at the beginning of the cutting process, commonly known as pierce height. The system is also responsive to the torch tip collisions with the workpiece during the cutting process commonly known as vertical collision control. The system also fills the role of the upper and lower limit switch.
Claims4
A torch height control apparatus for positioning the tip of a cutting torch with respect to a workpiece, said apparatus, comprising:
- a linear positioning mechanism, said as torch lifter including vertical torch transport mechanism with synchronous belt drive, altering wheelbase of the wheel axis and the solid body, attached to the synchronous belt, operable to move the torch between upper and lower limit;
- and
- control circuit means responsive to the switch signal for operating the torch lifter to move the torch to the predetermined non-contact position.
