Abstract
A portable disintegrator to disintegrate a hole in a metal workpiece is disclosed. Disintegrator current and coolant are supplied to the working end of an electrode which is vibrated in advance and retract axial movements. Guide means either actually engages the workpiece immediately surrounding the hole to be formed or engages a part of the workpiece closely adjacent where the hole is to be formed in the workpiece. The main frame of the metal disintegrator may be counterbalanced for weight but is guided by hand with freedom of limited movement in two dimensions during operation of the disintegrator.
Claims18
A metal disintegrator having a frame supporting a guide means with an aperture in the guide means to receive and axially guide an electrode relative to a workpiece, means to supply disintegrator current and coolant to at least a working end of the electrode, vibrator means to vibrate the electrode in advance and retract axial movements, and insulator means between the workpiece and electrode, the improvement comprising,
- said guide means having a first portion for guiding the working end of the electrode and adapted to engage a first part of a workpiece closely adjacent the location of the workpiece contacted by axial movement of the electrode,
- said frame being portable and having freedom of limited movement in two dimensions during operation of the disintegrator,
- and annular coolant seal means in said guide means carried on said frame to have limited movement therewith, said coolant seal means having a curved surface cooperable with the workpiece and conformable thereto to inhibit coolant leakage therebetween despite slight movements in two dimensions of the disintegrator.
