Abstract

The invention discloses an elastic clamping device for sheet electrodes. The elastic clamping device comprises a fixing mechanism, an extrusion mechanism arranged on the fixing mechanism and an elastic positioning mechanism arranged on the fixing mechanism; the elastic positioning mechanism is provided with two positioning grooves used for inserting two sheet electrodes and an extrusion groove located between the two positioning grooves and used for extrusion of the extrusion mechanism; the groove wall surface, close to the extrusion groove, of each positioning groove is an elastic moving surface; the groove wall surface, away from the extrusion groove, of each positioning groove is a fixing positioning surface; the widths of the positioning grooves in a free state are larger than those ofthe sheet electrodes. The extrusion mechanism is extruded into the extrusion groove, so that extrusion force is applied to the two sides at the same time; the elastic moving surfaces of the positioning grooves on the two sides move towards the fixing positioning surfaces, so that the two sheet electrodes are clamped; and the extrusion mechanism extends out of the extrusion groove, and the positioning grooves are restored to the free state, so that the two sheet electrodes are taken out from the positioning grooves.

Description

technical field [0001] The invention relates to the technical field of electric discharge machining, and in particular, relates to an elastic clamping device for thin-sheet electrodes. Background technique [0002] The EDM process of the sealing groove of the blade is a key process, and its processing quality directly affects whether the blade can be delivered qualified. Because the sealing groove of the blade is thin, narrow and deep, the thickness of the electrode is generally only about 0.6mm, so the electrode for the EDM of the sealing groove of the blade is a thin sheet electrode with a thickness of about 0.5mm. In order to control the deformation, the flake electrodes are made of graphite, but graphite electrodes are hard and brittle, and are more prone to wear and tear than copper electrodes. On average, new electrodes need to be replaced every time a blade is processed, and the upper and lower edge plates of the blade Both need to process the sealing groove of the b...
