Device for setting the tool electrode for spark STRENGTHENING crankshaft journals

摘要

The invention relates to electrochemical and electrophysical methods of treatment and can be used for electroprocessing metals. The inventive device comprises a housing 1 that is attached directly to the machine frame, a special fastening bolt 2, which provides a fixed position of the body and fixing it to the frame krugoshlifovalnogo machine (Model 3A 423) and precise feeding of the electrode to the machined crankshaft journal, the two dielectric plates 3, on hold the processing electrode and prevents the breakdown of the electric current to the body and the two bolts for fixing to the plates of the electrode 4, thereby to achieve a fixed electrode tnositelno position of the workpiece, namely the crankshaft journal. The technical effect aimed at optimizing through electric hardening of the workpiece, increasing the productivity of electric-hardening device, simplicity and ease of manufacture. The technical result is achieved in that the device comprising a support base attached thereto two dielectric plates (strips), a guide in the form of an I-beam, a base (housing), a pair of rollers, cantilever hinges, wherein the apparatus is further provided with a fastening to the machine frame bolt providing stiffness, the horizontal and vertical position, and two bolts electrode in its stationary position.
