Positioning system for electrode in spark machine

The invention discloses a positioning system for an electrode in a spark machine, and relates to the technical field of spark machines. The positioning system comprises a workpiece reference point setting module, a standard ball setting module and an electrode setting module. The standard ball setting module can locate a workpiece reference point and an electrode reference point by utilizing a standard ball point striking mode, is connected with the workpiece reference point setting module, and is also connected with the electrode setting module. The electrode setting module is connected withthe workpiece reference point setting module through the standard ball setting module. The workpiece reference point setting module is used for controlling a workpiece according to positioning data ofthe standard ball setting module. The electrode setting module is used for controlling an electrode according to positioning data of the standard ball setting module. An electrode moving position corresponds to the position,
